<![CDATA[Fatigue strength of composite plates with internal damage]]> Mon, 15 Oct 2018 13:22:30 +0200 Romanowicz, Paweł Janusz; Składanowska, Katarzyna
rodzaj: materiały konferencyjne w książce
Abstrakt: The composite materials are exposed for different forms of damages such as: delamination, debonding, fiber or matrix cracking, interference failure, etc. Very often such damage mechanisms may occur inside the composite structure. In some cases it may lead to the reduction of the mechanical properties, fatigue strength or load-carrying capacity. Composite materials are widely used in different applications (i.e. aerospace or automotive structures). In such constructions they are exposed for different loading conditions, including the most important, such as fatigue or impact loadings [1]. The Authors investigations are focused on the numerical and experimental studies of the fatigue life assessments of multilayered composite plates with internal damage. The experimental tests are performed for cyclic tension and tension-compression regime on the samples made of glass/epoxy composite materials. The width of the tested samples is 200 ÷ 250 mm. The special attention is focused on the influence of the internal delamination and shape of the open hole on the fatigue life of the damaged multilayered composite structure. Such problems can be investigated using different theories. The most popular methods are based on the stiffness or strength degradation models, progressive damage model, fuzzy set methodology [2] or the fracture mechanics. In the Authors investigation the problem of the delamination growth is studied using the fracture mechanics, whereas the fatigue life of the plate with hole is estimated using the stiffness degradation model and fuzzy logic analysis [2].]]>

rodzaj: materiały konferencyjne w książce
Abstrakt: Post-war investments, rapid development of industry and demographic changes contributed to the strong urbanization of medium and small European cities. Migrations broke inhabitants ties with their places of residence. Over the years, stories and legends about former residents and many local traditions have been forgotten. There are few traces left in the street names, urban systems and architectural details. Currently, they are readable only for trained eyes. Proper exposure of intangible heritage can contribute to change of the image of the city and support economical development. Selected cultural trails projects prepared by students of Landscape Architecture at the University of Rzeszów present various opportunities of discovering and feeling the city - its climate and characteristics, that are hidden in its intangible dimension. Cultural trail as a specific travel offer, allows to uncover the character and mysteries of seemingly ordinary places. This is important for the development of tourism, as well as strengthening of local awareness.]]>
<![CDATA[The Influence of the Velocit Dispersion on the Velocity–Density Relation in the Disk Model of the Galaxy]]> Mon, 15 Oct 2018 11:30:51 +0200 Sikora, Szymon; Bratek, Łukasz; Jałocha, Joanna; Kutschera, Marek
rodzaj: artykuł
Abstrakt: Taking the velocity dispersion term into account in the Jeans equation describing the disk model, counterintuitively allows to reduce the local mass-to-light ratio at the outskirts of flattened galaxies, and stop the unbound growth of mass function. This is possible thanks to a more intertwined relation between the gravitational potential and the rotation curve than for spheroidal systems. This effect is illustrated on the example of galaxy UGC 6446 by finding iteratively the column mass density from the rotation curve supplemented with an isotropic velocity dispersion profile in the disk plane. Along with galactic magnetic fields, this effect would allow to reduce the local mass-to-light ratio at the galactic outskirts.]]>

Abstrakt: Electrical generators for today’s Small Hydropower Plants (SHP) are designed for a constant rotation speed. Changes of energy provided by water depend on water flow, which is very unreliable for small rivers. Therefore, full efficiency can be achieved for power technology with generators working at a variable speed. This paper presents a concept of a energy conversion system optimization for application in a SHP which is based on a permanent magnet (PM) generators with a pr opeller turbine integrated with the generator rotors. These PM generators can work at a variable speed and therefore energy produced by the PM generators have to be converted by means of a power electronic unit to fit to the three-phase power grid parameters. The elements of such SHP are described. Due to non-linear turbin e characteristics it is necessary to formulate a suitable control algorithm for the whole system of energy conversion theref ore the control system principles for optimal power dividing on two exemplary hydro-sets are discussed.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Designing houses seem to be a trivial issue only if the environment does not set any requirements, and when geotechnical conditions are ideal. Leaving aside the complex problems of the relationship between the designer and the client and between the designer and the architectural administration, there are significant issues concerning architectural form, function and structure. Complications arise in cases of difficult spatial conditions, arising under existing local spatial development plans, as well as in the case of locations that feature complex geotechnical conditions. Designing a singlefamily home for very a demanding client in the middle of a big city, in the immediate vicinity of other structures and greenery protected due to architectural conservation and - in addition - located almost exactly on the outcrop of a mine, is already a kind of challenge for all the parties involved in the whole process of design and, subsequently, construction. The paper presents the manner in which these complex problems have been solved, illustrating important issues using fragments of the structural and architectural technical design, as well as photographs of the construction process.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: The cobalt, manganese, and iron salts of tungstophosphoric or molybdophosphoric acid with growing content of metals were applied for the first time as catalysts in the Baeyer-Villiger (BV) oxidation of cyclohexanone to ε-caprolactone with molecular oxygen. The catalysts were characterized with Fourier transform infrared spectroscopy (FTIR), X-ray fluorescence (XRF), and ethanol decomposition reaction. Introduction of transition metals into the heteropoly structure increases the activity of resulting heteropoly salts in comparison with parent heteropolyacids. It was shown that the most active catalysts are salts of the heteropoly salts with one metal atom introduced and one proton left (HMPX) type, (where M = Co, Fe, Mn, and X = W, Mo) with the metal to proton ratio equal one. Among all of the studied catalysts, the highest catalytic activity was observed for HCoPW. The effect indicates that both the acidic and redox properties are required to achieve the best performance. The Baeyer-Villiger (BV) oxidation mechanism proposed identifies the participation of heteropoly compounds in three steps of the investigated reaction: oxidation of aldehyde to peracid (redox function), activation of carbonyl group (Lewis acidity), and decomposition of the Criegee adduct to ε-caprolactone (Brønsted acidity)]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: The paper investigates a significant influence of transients on steady states in a matrix converter with the one-periodic control strategy. Proposed controller can be used as an interconnection device within a power system for a power flow control. However, the presence of inductances in external systems has the significant influence on steady state of a matrix converter operation. The special current injection method has been developed to ensure a proper operation of a matrix converter. Presented analysis of steady states is carried out in a frequency domain using the harmonic balance method. Obtained numerical results, which are confirmed by a time domain analysis, prove the effectiveness of the proposed method.]]>
<![CDATA[Temperature distribution in a steel beam-to-column joint when exposed to fire. Part 1: End-plate joint]]> Mon, 15 Oct 2018 08:21:07 +0200 Maślak, Mariusz; Suchodoła, Maciej; Woźniczka, Piotr
rodzaj: artykuł w czasopiśmie
Abstrakt: Temperature distribution usually observed in steel beam-to-column end-plate joint after 15 minutes of its standard fire exposure is presented and discussed in detail. Two types of joints are analysed for comparative purposes. The first one is a pure steel connection while the other is covered by a reinforced concrete slab. Numerical simulation of the considered joint heating scenario was performed using the 3D model in the ANSYS environment. Some results were additionally verified by simpler calculations carried out on 2D models using the SAFIR computer program. It is emphasized that due to the local accumulation of many massive steel plates the representative temperature values identified in particular joint components are significantly lower than those which at the same time are measured in beam and column outside the connection. This means that the classic assumption of even temperature over the entire length of all the structural elements of a frame load-bearing structure exposed to fire at any time during such fire, without distinguishing in the formal model any cooler nodal elements, is always safe but very conservative. In addition, as the fire develops the differentiation between the temperature values relating to the beam web and to the beam flanges becomes more visible. This effect is particularly significant in the presence of a massive floor slab adjacent the upper flange of a frame I-beam which effectively cools it.]]>

Abstrakt: The Electrochemical M achining process (ECM) can be applied for shaping advanced conductive materials which are difficult or impossible for machining using conventional methods. In electrochemical machining the workpiece is ananode and material is removed as a result of electrochemical reactions . This mechanism of material removal makes it possible to obtain high metal removal rate and good surface layer quality when machining parts made of super alloys , alloys , steels and some composite materials on metallic base . The very important but difficult problem is ECM process mathematical modeling because the phenomena occurring into intere lectrode gap are very complicated. In order to simplify the mathematical modeling it is necessary to introduce some modification of the ECM sinking process by : application of pulse voltage (Pulse ECM) often correlated with electrodes vibration , ECM ma chining with universal electrodes. The other important directions of ECM process development are: manufacturing processes by electrochemical deposition and some hybrid processes as electrochemical electrodischare or electrochemical grinding machining.]]>

Abstrakt: The article presents the results of the Double Punch Test (DPT) conducted on cement-lime mortar. The tested specimens have dimensions of 5 cm × 5 cm with a thickness of 12 mm and were obtained from bed joints of clay brick prisms prepared in the laboratory. For DPT purposes, 20 mm diameter steel punches were used. The reference mortar compressive strength was measured on standard specimens (4 cm × 4 cm × 16 cm), and the stress–strain relation was measured on cylinders (5 cm × 10 cm). Based on the reference compressive strength and DPT results, the correlation factor was established. The effect of the capping on the DPT strength was also measured and analyzed. Moreover, an individual FEM model was built and calibrated to simulate the DPT specimen failure mode and load-displacement behaviour. The results of the numerical simulations were compared to laboratory tests.]]>

Abstrakt: Organizacja wystawy światowej to dla miasta-gospodarza szansa wykorzystania tego wydarzenia o globalnej skali dla własnego rozwoju poprzez m.in. poprawę jakości przestrzeni publicznych, transportu, bazy turystycznej, powstanie nowych obiektów kultury, ale też budowy wizerunku i wyższego pozycjonowania na arenie międzynarodowej. Wykorzystywane do budowy miasteczek Expo rozległe, często zaniedbane czy zniszczone przez przemysł tereny są odzyskiwane dla miasta, przyczyniając się do jego rozwoju. Po zakończeniu wystawy miasto otrzymuje tereny wyposażone w infrastrukturę architektoniczną, techniczną i zieleń oraz obiekty, które nadal funkcjonują i benefitują dla miasta. W wyniku tego procesu często udaje się zrealizować założenia synergii, rozumianej jako synteza energii, wyrażone umownie równaniem „2+2=5”. Spoiwem synergicznie wiążącym struktury post-Expo z miastem są jednoczące je ciągi czy strefy przestrzeni publicznych (np. Paryż 1889, Barcelona 1929, Seattle 1962), a także włączanie terenów post-Expo w systemy zieleni miejskiej (np. Barcelona 1888, Chicago 1893, 1933, Sewilla 1929, Nowy Jork 1939, 1964, Szanghaj 2010). Nie zawsze jednak potencjał terenów post-Expo jest efektywnie wykorzystywany. Czasami pozostają one izolowanymi wyspami, które wprawdzie dają atrakcyjną ofertę funkcjonalną (np. Sewilla 1992, Mediolan 2015), ale poprzez brak urbanistycznej synergii z miastem, nie generują takich korzyści, jak w przypadku struktur synergicznie powiązanych.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: The study is concerned with the Baldwin effect and Lamarckian evolution in a memetic algorithm for Euclidean Steiner tree problem (ESTP). The main aim is to examine the importance of the proposed local search procedures for the ability of the algorithm to find solutions to ESTP. Two local search procedures are proposed as a part of an evolutionary algorithm for ESTP, and the effect of their use is carefully analyzed. The correction procedure modifies the given chromosome so that it satisfies the degree and angle conditions in ESTP. The improvement procedure actively adds new Steiner points to the evaluated solution. The modified solutions are accepted with varying probability, leading to a spectrum of algorithms with a Baldwin effect on one end and Lamarckian evolution on the other. The results are carefully analyzed using proper statistical procedures (Friedman test and post-hoc procedures). To further check the ability of the proposed algorithm to find the optimal or near optimal solutions, results for problems from OR-Lib are provided.]]>

Abstrakt: The paper presents a method and algorithm for determining input signals which maximise the dynamic error expressed by means of its absolute value. Being maximum, the values of these errors are valid for any dynamic signal which might occur at the input of a real system. In this way all the possible signals are taken into consideration at the same time. It should be stressed that these can be non-determined signals whose form cannot be predicted a priori. Two types of signals are taken into consid-eration: signals with a magnitude constraint and signals constrained in magnitude and rate of change. Solutions derived in the paper enable calculation of the absolute value of error by means of analytical formulae which give precise results and can be realised in a very short time.]]>

Abstrakt: Human perception of vibration could be the basic parameter in designing a new buildings located close to public transport. It is also one of parameter that is considered in diagnosis of building vibration. People perceived vibrations through the floor. The problem of floor vibration appear especially in old historical buildings with wooden floor when source of transport vibration change because of infrastructure development. During years road, tramway or railway infrastructure is more expanded that it was when the old buildings were built. That is why new solutions of protection against noise and vibration are needed. One of that kind solution could be vibro-acoustic floor which can reduce impact sounds and vibrations. A flooring system that insulates both acoustically and vibrantly is a common solution to reduce noise coming from impact sounds or to propagate from lower levels to higher ones and to limit the influence of vibration on people receiving vibration in buildings passively. The flooring system should therefore be capable to damp vibrations up to 100 Hz and have sound insulation of min. 25 dB. The composition of vibration insulation materials and their material parameters will be selected to optimize the acoustic and vibration protection. At the same time, the acoustic and vibration-insulating flooring system should have all the functional features that are common to the floor: ease of installation and adequate rigidity. In paper three types of vibro-acoustic floors will be considered: with full vibro-insulation, with insulation strips and with point insulation. Advantages and disadvantages of these three considered solutions will be presented. The paper is pilot study to in-situ measurement which will be held under the project of EU commission support.]]>

rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: This paper presents a selection of vibration measurement results and analyses performed with regard to their harmfulness to residential buildings. The first part of the paper refers to the analysis of railway vibrations measured in situ at the foundation level of residential building. These vibration records were then used to assess the harmfulness of vibrations relating to each train speed. Assessment of the vibration harmfulness of the building was performed with an indicator of the perceptibility of vibration through a structure (WODB), according to the Polish standard. The second part of the study refers to the creation of dynamic models of buildings with the use of the ‘Diana’ software program and analysis of their responses to railway vibrations. The thresholds specified by the standard in any of the train speeds of up to 250 km/h were not exceeded. Nevertheless, propagation of vibrations induced by train passages and their effect on the structural response of buildings is a complex phenomenon. Without in situ measurements, it is hard to assess the impact of induced vibrations on buildings. As proven in the paper, a train moving on a track at various speeds does not uniformly make the vibration greater in each frequency band.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Based on the numerical simulation performed within the Abaqus computational environment for a typical end-plate beam-to-column joint the influence of the endplate thickness on the effective joint rigidity has been verified. The initial joint rigidity at first determined for 20 mm thick end-plate has been compared with rigidity of the joint constructed with substantially more flexible end-plates 10, 8 and 6 mm thick. In all the considered cases the column was equipped with horizontal ribs stiffening the web at the height of beam top and bottom flange. No diagonal ribs were applied. In addition the column flange at the zone directly adjacent to the beam end-plate in all the analyzed cases has been set to 30 mm. This way it did not affect the computationally determined rigidity of considered joints. Juxtaposition of M-j curves characterizing the considered joints and depicting the relationship between the applied bending moment and relative change of the initial angle between undeformed axes of beam and column in the analyzed frame indicates qualitatively different modes of destruction of the considered joints, and thus different computational models determining their bearing capacity. In the first case obtained parameters seem to indicate that the joint is nominally rigid but in all the remaining cases the bearing capacity seems to be exhausted by the increasing deformation of the more and more flexible end-plate.]]>
<![CDATA[Critical temperature evaluation for a steel frame with joint stiffness decreasing in fire]]> Fri, 12 Oct 2018 09:20:57 +0200 Maślak, Mariusz; Pazdanowski, Michał; Snela, Małgorzata
rodzaj: artykuł w czasopiśmie
Abstrakt: A procedure to determine the critical temperature of a selected steel frame bearing structure is presented and discussed. This temperature, in case of fully developed fire, when the temperature of the exhaust gasses enveloping the structural members is equalized within the whole fire zone, may be considered as an impartial measure of safety. The obtained result does not depend on the heating progress but only on the static scheme and the load level in the considered structure. The quantitative and qualitative evaluation of the influence the joint stiffness decreasing in fire exerts on the resultant critical temperature constitutes the basic objective of the authors. It has been shown, that proceeding according to the recommended computational procedure does not necessarily result in an estimate fully unambiguous in interpretation. The critical temperature specified in a global mode, for the whole considered frame, is usually associated with a specific component of such frame, interpreted as the so called “weakest link”. Thus local loss of bearing capacity in such element is in this approach equivalent to the total destruction of the whole bearing structure. Indication, which of the components present in the considered frame should be treated as the critical one, because of its behaviour under fire conditions, seems to be a key to the forecast safety level warranted to the users of the structure. The authors show, that this association changes depending on the selected computational method, and this in turn substantially limits the reliability of the obtained estimate.]]>

Abstrakt: The paper presents the results of analyzes concerning the variation in daily traffic volumes of buses during the year. Based on them, typical groups of seasonal and weekly variation of buses were identified, along with the way in which they were assigned to a particular section of A-class or S-class roads. For the homogeneous traffic groups obtained in this way, representative traffic volume variation profiles were determined enabling direct calculation of volumes from daily measurements into AADT buses, which is a departure from the present approach (profiles determined for all vehicles). Additionally, the most favorable period for conducting measurements at random, that allows for a reliable estimation of AADT (the smallest AADT estimation error and lowest traffic variation), was determined. The results obtained can help to better estimate the traffic volume of buses and thus better design the road infrastructure.]]>

rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: The operation of steam boilers with high efciency requires control of thermo-hydraulic and strength parameters in the on-line mode. During operation under transient conditions, there are signifcant temperature differences over the circumference of the horizontal pressure vessels. This occurrence is caused by the different values of heat transfer coefcients on the inner surface of the boiler drum in the water and steam region. Large thermal stresses can occur in partially flled horizontal vessels. This takes place in large steam generator drums, superheater headers, and steam pipelines. The paper presents a method for determination of thermo-flow parameters for steam boilers. This method allows performing the calculations of the boiler furnace chamber and heating flow rates absorbed by superheater stages. These parameters are important for monitoring the performance of the power unit and determining the degree of the furnace chamber slagging. Knowledge of these parameters allows determining the degree of the furnace chamber slagging. The calculation can be performed in online mode and use to monitoring of steam boiler. The presented method allows to the operation of steam boiler with high efciency.]]>

rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: Architectural designs are based on spatial, functional and technological ideas. We can often see buildings and technical solutions used in them that emulate other constructed examples in a single or multiple aspects. An obvious affinity of both structures is usually the result of inspiration by architects in their creative thinking. Sometimes, it is some artefacts or natural objects, which are at the origin of architectural ideas. Seemingly, such inspirations might look as an easy take. But the task of successful implementation of such inspired ideas in the case of complicated structures like buildings involve many potential pitfalls. A cautious approach to such a procedure seems to be rational. In order to avoid unexpected problems and disillusions, being the result of direct borrowing from the sources of inspiration, some preventive measures should be taken. This concerns both practising architects and students in architecture. Therefore a special teaching method should be devised and implemented.]]>

rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: The paper is devoted to test results of air flow through natural ventilation supply-exhaust ducts in the rooms located on the upper floor of the building that were conducted in ANSYS Fluent software. Three types of solutions were selected for the tests: air inflow into the room through the air intake located at the basement level, air inflow through the window ventilator (although no longer used, this solution can be found in many existing residential buildings) and the natural ventilation system supported with the so-called “solar chimney” that is usually a glass superstructure, located on the roof of the building above the ventilation ducts. All simulations were conducted with an outdoor temperature of +3 degrees C. The indoor temperature is + 20 degrees C, considered to be the minimum thermal comfort level. The simulations concerned such issues as: pressure system inside the room and in the exhaust duct, distribution of air temperatures in the room, vector direction of air flow through supply and exhaust ducts and in the room. Tests conducted using a computer method of air flow analysis in ducts and in the analysed room indicate that the developed natural balanced ventilation system is a good solution, especially when building sealing is so common. In all cases presented, it meets the normative regulations and requirements for the ventilation air stream and the air exchange rate in the room. The paper (second part) describes test results concerning the room located on the upper floor of the building, i.e. with a long 9-meter long supply duct and a short 3-meter long exhaust duct.]]>

Searching for the currents spectrum components was conducted basing on the form of magnetic field energy function. The nonlinear function approximating main field energy versus magnetising flux linkage consist of all windings main flux linkages. The leakage fluxes of winding were omitted because the research has been limited to the motor free running only. The specified current frequency components were sought in the measurement current spectra of tested double-cage motor. The positive and negative symmetrical components of frequency components being multiplication of supplied frequency are produced by the stator core anisotropy. The frequency components dependent on rotor slip are generated by the rotor core anisotropy. Presented results may be useful in the diagnostic of induction motors.]]>

Abstrakt: In this paper the circuit-oriented model of the 3-phase induction machine with a double stator winding was developed. The double winding (dual winding) is created by two 3-phase windings mutually displaced by 30 electrical degrees. The machine model is presented as the circuit composed of resistances, inductances and controlled electrical sources. It results from the transformed voltage equations. Such a model is not offered by the Simulink library, however it can be directly introduced using Sim-Power-Systems and additionally into other circuit simulators as the Spice family programs. The whole model can be masked and connected with other models of power electronics, electrical sources or various electrical and mechanical devices. Operation of the frequency controlled drive, where the both stator windings were supplied with two current source inverters, illustrates application of this circuit oriented machine model. Further applications have been left for the users invention.]]>

Abstrakt: A key element of the system IACS is the verification of the parcel area covered by direct subsidies. Control measurements are made by FOTO method, and in a small part by the direct inspection. Statistical methods are used in estimating the significance of differences. The results of such analysis are correct only when the empirical distributions are consistent with the theoretical ones. The problem of distribution adequacy is presented in the paper on the examples of three objects. The hypotheses about the possibility of using the commonly used distributions, and the appropriateness of the modification of the density curves were verified. By questioning the effectiveness of current methods of analysis, the authors point to the advantages of robust statistics. The cognitive effect of the analysis is to indicate the Laplace distribution as a statistical model of the analyzed differences. Research is concluded by proposal of post-control report that sums up relevant properties of the survey results.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Na początku lutego 2017 roku doszło do awarii płyt bystrotoku na przelewie stokowym zapory Oroville w Kalifornii w Stanach Zjednoczonych. Po raz pierwszy w 50-letniej historii zapory pracował przelew awaryjny, co skutkowało ewakuacją 180 000 osób mieszkających poniżej zapory. Niespełna rok po tym zdarzeniu wydany został niezależny raport śledczy dotyczący przyczyn. Raport zawiera kompleksowe informacje dotyczące okresu projektowania i wykonawstwa, eksploatacji i remontów, a także ocen stanu technicznego i analiz bezpieczeństwa. Poniższy artykuł przedstawia kluczowe wnioski z przeprowadzonej ekspertyzy. W przypadku incydentu na zaporze Oroville doszło do serii zdarzeń oraz problemów eksploatacyjnych dla dwóch obiektów towarzyszących: przelewu stokowego oraz przelewu awaryjnego. Główną przyczyną inicjacji zniszczenia przelewu stokowego była siła wyporu pod płytami bystrza, spowodowana przez pęknięcia betonu oraz nieprawidłową pracę drenaży. W wyniku tego nastąpiło odsłonięcie i degradacja podłoża skalnego o niskiej wytrzymałości oraz rozmycie znacznej części bystrotoku. Konsekwencją tych zdarzeń była praca przelewu awaryjnego, którego stateczność była zagrożona w wyniku postępującej erozji w kierunku stopy przelewu. Przedstawiono nieprawidłowości na etapie projektowania i wykonawstwa, nieprawidłowości na etapie eksploatacji, nieprawidłowości w ocenie stanu technicznego oraz standardach bezpieczeństwa zapór.]]>

Abstrakt: Electrical generators for today’s Small Hydropower Plants (SHP) are designed for a constant rotation speed. Changes of energy provided by water dep end on water flow, which is very unreliable for sma ll rivers. Therefore, full efficiency can be achieved for power technology with generators working at a vari able speed. This paper presents a concept of a energy co nversion system optimization for application in a S HP which is based on a permanent magnet (PM) generator s with a propeller turbine integrated with the gene rator rotors. These PM generators can work at a variable speed and therefore energy produced by the PM gener ators have to be converted by means of a power electronic unit to fit to the three-phase power grid paramete rs. The elements of such SHP are described. Due to non-line ar turbine characteristics it is necessary to formu late a suitable control algorithm for the whole system o f energy conversion therefore the control system pr inciples for optimal power production and hydro-set operatio n in stable way are discussed.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Na potoku Trzebuńka w miejscowości Stróża podjęto i zrealizowano projekt polegający na obniżeniu o 4.0 m i rewitalizacji istniejącej zapory przeciwrumowiskowej, przebudowując jej konstrukcję poniżej tworząc bystrza z głazów osadzonych w konstrukcji betonowej (tzw. „grouted rock”). Całość konstrukcji tworząca 12 małych zbiorniczków na wodę stanowi obecnie rodzaj przepławki dla ryb. W artykule przedstawiono wstępne wyniki analizy przebiegu procesów korytowych na potoku Trzebuńka powyżej przebudowanej zapory. W literaturze światowej opisane są lokalne przypadki zlikwidowanych lub obniżonych i przebudowanych wielu zapór różnej wielkości. Wciąż brakuje jednak odpowiedzi na wiele pytań dotyczących reakcji koryta na taką interwencję. Dyskutowany jest problem tempa przemieszczenia materiału zdeponowanego w zbiorniku i konsekwencji obniżenia bazy erozyjnej dla odcinka koryta powyżej zapory. Po dwóch latach od przebudowy zapory i uwolnieniu rumowiska z czaszy zbiornika, przeobrażenia nowo ukształtowanego koryta powyżej nowej konstrukcji mają przebieg dynamiczny. Wyniki pomiarów koryta Trzebuńki na odcinku o długości 180.0 m powyżej nowej zapory wskazują na zdecydowane migracje boczne koryta (erozja boczna). Dopiero powyżej 200.0 m od korony nowej konstrukcji koryto wykazuje stabilność.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: The ground temperature changes with depth and time. Time variability is considered as a harmonic function. The equation describing changes of the ground temperature contains four parameters: the average annual temperature of the surface of the ground, the annual amplitude of the temperature of the ground surface as well as the phase angle of the temperature and thermal diffusivity of the ground. Based on the results of the measurements presented in the literature, the parameters of the equation using the combined method on the basis of linear regression, described in the literature, were determined. This method, however, leads to an ambiguous value of the thermal diffusivity. It was found that the nonlinear regression method gives much better results, leading to obtaining precise and unambiguous values of all parameters of the equation.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: The goal of this article was to review the literature which discusses the problem of oily wastewater purifi cation by membrane fi ltration. The authors focused on membranes containing zirconium compounds, mainly ZrO2, used in pressure driven membrane processes. The effi ciency of the oil removal processes for various membranes (ceramic and composite), usually above 95% for the oil contaminated sewage, was compared. The infl uence of zirconium compounds on the properties of ceramic membranes was also discussed. The methods of producing ceramic membranes have been briefl y characterized as well. Ceramic membranes are usually obtained by sol-gel technique but also by isostatic compression, reverse phase technique, or hydrothermal crystallization. Ceramic membranes are formed with zirconia, which cause an increase in fi ltration effi ciency by improvement of hydrophilic properties of the membrane. Moreover, the addition of ZrO2 results in increased chemical and hydrothermal membrane stability. The effi ciency of the fi ltration processes using the presented membranes was high, suggesting that membrane fi ltration processes are highly effective purifi cation methods.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Skin aging is a complex process which involves all the layers of the epidermis and dermis. In order to slow skin aging, methods are researched which would strengthen and protect skin stem cells. Science is in search of the right method to stimulate the proliferation of epidermal stem cells. Plant stem cells show outstanding anti-aging properties, as they can, among other activities, stimulate fibroblasts to synthesise collagen, which, in turn, stimulates skin regeneration. One of the most important agents which give anti-aging properties to plant stem cell extracts is kinetin (6-furfuryladenine). This compound belongs to a cytokine group and is considered to be a strong antioxidant which protects protein and nucleic acids from oxidation and glycoxidation processes. It enables cells to remove the excess of free radicals to protect them from oxidative stress.]]>

Abstrakt: Nanostructured lipid carriers (NLC) composed of the substances generally recognized as safe (GRAS) were obtained by using a hot high-pressure homogenization technique (HPH). The influence of the number of homog enization cycles and concentration of a decyl glucoside surfactant on the NLC properties were studied. The sys tem’s stability was assessed by macroscopic observa tion, light backscattering and zeta potential measure ments. NLC particle size was measured using dynamic light scattering (DLS). The kinetically stable formulations were loaded with forskolin and selected for in vitro drug permeation study using the Franz cell method. Concen tration of forskolin in the receptor solution (i.e. ethanol/ PBS mixture) was analyzed with high performance liquid chromatography (HPLC) with UV detection. The obtained results have shown that NLC formulations could be used as effective carriers for forskolin permeation through the skin.]]>
<![CDATA[The basement of residential buildings as part of radon preventive measures]]> Wed, 10 Oct 2018 10:05:02 +0200 Kusionowicz, Teresa
rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: he Directive 2013/59/Euratom was adopted by the Council of the European Union in 2013. It lays down basic safety standards for protection against the dangers from exposure to ionising radiation. The directive obliges our country to adopt the laws, regulations and administrative provisions necessary for its implementation. According to research conducted by the Institute of Nuclear Physics in Kraków, radon constitutes the largest source of ionising radiation a resident of our country is exposed to. Its share reaches almost 40% of the annual dose. Inhalation of radon and products of its decay in rooms constitutes a significant part of the dose of ionising radiation whose source is radon. Residential premises are the rooms in which we spend nearly 60% of our life in our climate zone. Environmental studies conducted in these rooms demonstrate that the concentration of radon in their interior is in many cases greater than its concentration outside the building. This issue is dealt with in Article 74 of the Directive 2013/59/Euratom. It recommends taking action to prevent long-term health risks resulting from exposure to radon in residential and public premises. Architectural and construction solutions applied in buildings play a significant role in the prevention of such dangers. One of the radon preventive measures in the indoor environment is the design of basements in residential buildings.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Users of machines and engineering devices force continuous improvement of their functionality and efficiency while reducing energy consumption. For this purpose, numerous sensors are installed in the machines in both drive systems and execution systems. Sensors are a source of information for control units and also allow reading parameters during diagnostic tests. The diagnostician should have the appropriate interface and knowledge of the operating principles of the tested machine. In order to facilitate the implementation of the diagnostic process even by less experienced service personnel, it is proposed to use a diagnostic interface based on the application developed in the Android system, which main element is a QR code scanner. The system uses Matlab-Simulink, data base and PHP script to work properly. This system allows performing a diagnostic test and identifying potential causes of device failure. The system has friendly interface where is implemented many useful things like graphs and visualization of device movement. The application reads the nominal operating parameters stored in the QR code of the machine and displays the next steps necessary to assess the technical condition of the object. On the basis of a comparison of registered and nominal machine parameters, the application indicates possible fault locations. The implementation of the database on an external server allows the application to run anywhere on android devices that have access to the internet. Through the registration process it is possible to create a database of employees who have access to the system. The diagnostic system for storing all information, such as employee data or current sensor measurement values uses the MySQL database. Preliminary tests of the application carried out during diagnostics of the hydraulic and mechanical system of the building manipulator confirmed the functionality of the developed system.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Constantly increasing technical and operational demands are set for modern manned and unmanned special vehicles, all − terrain vehicles, and mobile machines. Their producers must comply with very restrictive standards, strict legal regulations, and high customer requirements. They concern not only functionality and efficiency of described objects, but also resistance to the impact of environmental and climatic exposure. Vehicles and mobile machines must be adapted to work in different climatic conditions such as low and high temperature, variable humidity, wind, dustiness, rainfall, variable atmospheric pressure, solar radiation. Verification of the correctness of operation of all these systems installed in machines, vehicles and engineering units requires experimental research in specified and stable climatic conditions. These special conditions can only be implemented in a thermoclimatic chamber. Thanks to these researches, it is possible to confirm the effectiveness of solutions that allow machines to work in extreme climatic conditions, as well as to detect a number of defects and imperfections of the structure, unpredictable at the design stage. The article describes the research procedure certified by Polish Centre for Accreditation and discusses examples of technoclimatic research carried out recently in the thermoclimatic chamber of Laboratory of Technoclimatic Research and Heavy Duty Machines of Cracow University of Technology.]]>

rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: This paper explores the use of Jaya algorithm for the single-and multi-objective design optimization of plate-fin heat exchangers (PFHEs). Design of PFHEs involves a number of geometric and physical parameters with high complexity. The general design approaches are based on trial and error and become tedious and time consuming and do not guarantee the achievement of an optimal design. Therefore, advanced optimization algorithms are preferred. The Jaya algorithm is a newly developed simple algorithm and it does not have any algorithmmic-specific parameters to be tuned and this aspect reduces the designer’s effort in tuning the parameters to arrive at the optimum value of the objective function. The Jaya algorithm is proposed for the design optimization of PFHEs by minimizing the total surface area of heat transfer, total annual cost, and total pressure drop of the system and maximizing the effectiveness. Seven design parameters are considered which are imposed by constraints on the design. Single- as well as multi-objective design optimization is carried out using the proposed algorithm. The results obtained by Jaya algorithm are compared with the results of latest reported algorithms. These comparisons revealed that the Jaya algorithm can be successfully applied for the design optimization of PFHEs.]]>

rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: Every modern city in the 21st century should enable its residents to quickly and easily move to other cities within the country, Europe and the world. This is very often implemented through air transport. An inseparable element of this type of conveyance is the presence of facilities such as airports in the vicinity of cities. In 2015, a set of 17 Sustainable Development Goals [1] was established by the United Nations. Their task is, inter alia, environmental protection. These goals should also be taken into account in the management of passenger airports. The article presents a critical review of the feasibility of selected sustainable development goals through solutions in the field of environmental engineering. These include green walls and roofs, the use of renewable energy, and devices that effectively save water and energy. Then, an analysis of the possibilities of their application at passenger airports was carried out. The use of devices increasing the efficiency to achieve sustainable development goals for already implemented solutions was also taken into account. Sometimes a simple and inexpensive investment can significantly improve the quality of natural resources protection.]]>

rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: The progressing process of urbanization causes areas that were once previously green to turn into areas with a high rate of runoff. For this reason, all activities aimed at the alternative management of rainwater in the city are extremely important. The aim of the work is to compare the share of rainwater management in urban catchments to various alternative forms of management of these waters (including rain gardens and green roofs). The paper compares the outflows from the sample catchment with different runoff coefficients and after the implementation of various Low Impact Development (LID) practices to the catchment. The calculations were carried out using the Storm Water Management Model (SWMM) program version 5.1.012 with LID controls developed by the United States Environmental Protection Agency (US EPA). The rainfall data used to carry out the simulation was derived over the last three years from the meteorological station in Krakow.]]>
<![CDATA[Design value of a headed stud shear resistance in composite steel - concrete beams - probability-based approach to evaluation]]> Tue, 09 Oct 2018 10:16:28 +0200 Maslak, M.; Domanski, T.
rodzaj: materiały konferencyjne w książce
Abstrakt: Conventional standard procedure used to determine the design value of a headed stud shear resistance in composite steel-concrete beams is very simple but, in fact, mathematically incorrect, particularly in the case when such connector is automatically welded and when it is working in a solid slab. According to this approach the considered value is specified as a minimum of two separate design values. One of them is related to the resistance of the stud itself while the other is associated with the failure of the surrounding concrete. In the paper presented by the authors a new algorithm which allow to evaluate this value is recommended and discussed in detail. It seems to be more accurate because it is based on the fully probabilistic inference. In such approach a new random variable is introduced, being a minimum of two other, statistically independent, random variables. Analogously as it is in the concept previously mentioned, the first random variable quantifies now the steel stud shear resistance whereas the second one – the resistance of the adjacent concrete. Consequently, the sought design value is determined as a suitable quantile of this new random variable, characterized by log-normal probability distribution. It is shown that the design value of a headed stud shear resistance, calculated in this manner, strongly depends on the variability of strength parameters, relating both to the steel of which the connecting stud is made and to the concrete of the slab. In addition, it is found that in the case when the variability of concrete strength is too high, the safety factor recommended to use in European standards is not able to provide the required safety level, acceptable by the building users. The considerations presented in the article are illustrated by a detailed computational example.]]>

Przyczyną istotnych zmian w technologii wykonywania ścian stał się obecnie wymóg oszczędzania energii. Nie należy jednak zapominać, że podstawową funkcją tych konstrukcji powinno być dostosowywanie warunków środowiska geograficznego do potrzeb środowiskowych, klimatycznych i zdrowotnych, człowieka. Z uwagi na wymóg energooszczędności istniejące budynki mieszkalne poddawane są w ostatnich latach modernizacji termicznej poprzez docieplanie ich ścian zewnętrznych. Obserwacja modernizowanych obiektów ukazuje, że zastosowane w tym procesie technologie budowlane są bardziej podatne na rozwój korozji biologicznej niż miało to miejsce w tzw. tradycyjnym budownictwie. Celem pracy jest podniesienie problemu wyraźnie zwiększonego zakresu zagrożeń biologicznych w tych rozwiązaniach. Zjawisko to jest niezwykle niekorzystne i to nie tylko w zakresie trwałości materialnej struktury budowlanej i walorów estetycznych tej architektury. Szczególnie istotny jest zakres zagrożeń tego zjawiska w kontekście profilaktyki prozdrowotnej i postępu wiedzy medycznej na temat wpływu czynników mikrobiologicznych środowiska wewnętrznego pomieszczeń mieszkalnych na zdrowie człowieka. Pierwotnie technologie docieplania ścian zewnętrznych w systemie tzw. ścian dwuwarstwowych dopuszczone zostało jedynie w procesie modernizowania istniejących obiektów. Obecnie technologie tego typu są powszechnie stosowane także w nowoprojektowanych budynkach mieszkalnych. Rozwój zagrożeń biologicznych pojawiający się na modernizowanych obiektach już w krótkim czasie po dociepleniu skłania do analizy przyczyn tego zjawiska. Konieczne staje się określenie wymogów jakie powinny spełniać technologie budowlane stosowane w konstrukcji energooszczędnych ścian zewnętrznych w celu ochrony środowiska zbudowanego przed rozwojem zagrożeń biologicznych.]]>

Abstrakt: The electrochemical properties of 48 cationic, anionic and merocyanine polymethine dyes have been studied using cyclic voltammetry. The effect of structural parameters, viz. the chromophore charge, the donor-acceptor properties of the terminal groups, the polymethine chain length, and the molecular symmetry on the redox potentials are analyzed. The DFT calculations of all the studied dyes have been performed with three different exchange-correlation functionals (B3LYP, CAM-B3LYP, and B97D3) in both vacuum and acetonitrile using the PCM solvation model; additionally, for selected species the BP86, PBE0 and M06-2X functionals were employed. The HOMO and LUMO energies of the dyes obtained from voltammetry data are compared with those from the DFT calculations to select the best performing theoretical approach for evaluation of the frontier orbital energy levels and energy gap of these π-conjugated compounds. Linear correlation equations obtained from the data for 48 dyes may be employed for credible prediction of the HOMO and LUMO energies in the search for designed molecules with required redox properties. TD-DFT calculations have demonstrated that the pure (non-hybrid) BP86 and B97D3 functionals give a relatively low mean absolute error for excitation energies, proving to perform better than the hybrid functionals applied, especially CAM-B3LYP.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: The runoff coefficient is one of the basic hydrological characteristics of the catchment. It can be determined using multiannual, periodic, or annual data measurement sequences. The variability of the runoff coefficient can be influenced by the terrain, the land cover, and the land-use in the catchment, among other things. The present study is an attempt to analyse changes in the runoff coefficient over a period of 30 years (1984–2013) for 49 gauging sections located in the Carpathian part of the Upper Vistula catchment. An additional analysis was carried out to study the impact of changes in the land cover and land-use of the catchment on the value of the runoff coefficient. Rainfall and daily flows data was made available by IMGW-PIB, whereas land cover and land-use data of the catchment come from the CORINE Land Cover system (1990, 2000, 2000, and 2012).]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Regulations, definitions, and calculations related to emissions of Volatile Organic Compounds (VOC) from paints used for horizontal road markings (traffic paints) in North America and in European Union are different, which frequently makes simple comparisons impossible. To illustrate the dissimilarities, solvent packages of various exemplary paints that meet several normative requirements were compared for the nominal emissions according to different calculation procedures. For a unified assessment, volatile portions of the paints were evaluated based on Ozone Formation Potential (OFP). The analysis revealed that similar nominal VOC contents can lead to vastly different OFP, in an extreme case six times higher. Incongruously high OFP, which was calculated for emissions in Southern California despite strict limits can thus be explained. The provided calculations can be used by road administrators as a tool to demand materials with lowest environmental impact, by environmental researchers to pinpoint irregularities between declared and measured discharges, and can assist formulating chemists in selection of raw materials to prepare environmentally friendly road marking paints.]]>

Abstrakt: Evaporative CO2 has been selected as the main detector cooling technology for the Phase II upgrade of the LHC silicon detectors at CERN. In order to provide input to the ATLAS Pixel TDR about the minimum attainable cooling temperature by the end of 2017, ATLAS, with a contribution of CMS, has launched a dedicated detector cooling R&D study nick-named Baby-DEMO. The Baby-DEMO is the demonstration of a typical 2PACL CO2 cooling plant operating at the lowest temperature ever achieved. A real size ATLAS mock-up is used to hold realistic manifolding as its critical path might have strong impact on the cooling performance. Additionally, the “Baby-DEMO” program addresses the study of high power flexible vacuum insulated coaxial transfer lines and warm nose boiling enhancement as possible solutions for the Phase II upgrade. This paper describes the system design including CO2 plant, primary chiller and typical distribution. Challenges and solutions used to achieve the lowest possible evaporation temperatures are reported. The result of this study, even if at the preliminary stage, are of great interest for the design of the cooling systems that ATLAS and CMS will use in the Phase II era.]]>

Abstrakt: The purpose of this paper is to develop a procedure of the lower limbs volumetric modelling using the laser measurement arm and the evaluation of defects, which can cause disorders in the field of locomotion. The procedure is presented based on the analysis of two specimens: woman (age 22) and man (age 23), whose lower limbs are fully formed. The method includes the laser scanning and the lower limbs regularity evaluation based on the characteristic lines, which were identified during palpation examination of the skin and bones characteristic points or during the radiological examination. The valgus knee and the knee joint hyperextension were determined for the woman’s case and no deficiencies for the man’s case. Presented procedure has a screening application and can support the rehabilitation process. The advantage is that the developed method is noninvasive and the diagnostics can be performed while muscles are active in the natural standing position. The SL method was verified by the Laser Tracker system. On the group of 55 students with the average age of 10.4 years, the measurements were performed in order to define the influence of BMI on the correctness of the results, which were achieved while using the proposed method of the evaluation of the static deficiencies. No relevant influence of BMI on errors occurring in the determination of defects valgus and varus of the lower limbs.]]>

Abstrakt: Endoprosthesis stem fractures are among the rarest complications that occur after hip joint arthroplasty. The aim of this paper is to evaluate the causes of the fractures of the Aura II stem neck, which is an element of an endoprosthesis implanted in a patient. In order to achieve it, a radiogram was evaluated, the FEM analysis was carried out for the hip joint replaced using the Aura II prosthesis and scanning tests as well as a chemical analysis were performed for the focus of fatigue. The tests performed indicate that the most probable causes leading to the fatigue fracture of the Aura II stem under examination were material defects in the process of casting and forging (forging the material with delamination and the presence of brittle oxides and carbides) that resulted in a significant reduction of strength and resistance to corrosion. In the light of an unprecedented stem neck fracture, this information should be an indication for non-destructive tests of ready-made stems aiming to discover the material and technological defects that may arise in the process of casting and drop forging.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: This paper deals with the cost and energy efficiency for heat and electricity production. The operation of the medium size Combined Heat and Power plant, located in Poland, with diverse production units: steam boilers, water boilers and gas engines is studied. The analysis is performed for spring-autumn season, characterized by relatively low and variable heat power demand. Due to such mutable conditions production units are forced to operate out of the nominal efficiencies. The analysis is performed for heating and electric energy production on: steam boilers and turbo-generator, water boilers, steam boiler and gas engines; and water boiler and gas engines. To reflect the actual situation, a mathematical model for the complete installation is developed. The model calculates energy balance for a given heating power demand profile. The model is based on the actual parameters, including all technical aspects and equipment's limitations. The developed tool enables to select the mode of operation for each production unit separately or in combined mode. As a result, the energy balance in one hour operation period is calculated. Such approach allows to compare the energy production efficiency and cost in each system at every hour. Due to the fact, that nowadays heat and electricity production business, is strongly affected by legal regulations, the analysis of gas engines profitability with and without subsidy for natural gas based co-generation is performed. ]]>

Abstrakt: W procesie płukania filtrów pospiesznych wody można uzyskiwać oszczędności wody i redukować ryzyko utraty ziaren. Wyniki badań wskazują, że w przypadku prowadzenia płukania wodą powierzchniową konieczne jest zróżnicowanie intensywności płukania w zależności od temperatury wody, jeżeli oczekujemy tej samej wartości ekspansji latem i zimą. Brak takiego zróżnicowania może prowadzić do utraty ziaren, wody płucznej i energii zimą lub zbyt małej intensywności płukania latem, co skutkuje sklejaniem ziaren i w rezultacie ich częściową utratą.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: W dachach skośnych z izolacją termiczną układaną na krokwiach (np. z płyt poliuretanowych z okładzinami), warstwy termoizolacyjne i pokryciowe mocowane są bezpośrednio do konstrukcji dachu, dzięki czemu nie redukują przestrzeni poddasza, a także pozwalają wyeksponować konstrukcję więźby dachowej. W tym przypadku najczęściej wykonuje się szczelinowe dachy skośne wentylowane (rysunek 1), gdzie pokrycie dachowe mocuje się do podłoża konstrukcyjnego przez układ łat i kontrłat przykręconych do krokwi dachowych. Bezpośrednio pod pokryciem dachowym wykonywana jest szczelina wentylacyjna kształtowana przez kontrłaty. Górna powierzchnia izolacji termicznej w takimdachumoże stanowić dolną warstwę odwadniającą i wiatroizolację. Płyty termoizolacyjne układane są na powierzchni dachu na tzw. mijankę. Krawędzie płyt są fabrycznie frezowane dzięki czemu można je szczelnie łączyć. Takie rozwiązanie nie tylko zapewnia dobrą izolacyjność przegrody, ale również jej szczelność.Funkcje termoizolacji układanej na krokwiach Warstwa termoizolacji dachu powinnamieć taką grubość, aby zgodnie z [4] spełniała warunek Umax (od 2017 r. w przypadku budynków ogrzewanych Umax ≤ 0,18 [W/(m2K)]). Ze względów konstrukcyjnych dobrymrozwiązaniem jest stosowanie płyt o jak najmniejszej przewodności cieplnej (współczynnik λ płyt poliuretanowych wynosi 0,021 ÷ 0,024 [W/(mK)]).]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Water reservoirs play important role in human environment, especially as a part of ecological networks in urban areas. Due to such localization they are subjected to the effects of the anthropogenic activities, introducing broad range of contaminants (e.g. heavy metals) through various pathways. The main aim of this study was to estimate heavy metal (Cd, Cr, Cu, Pb, Zn) contamination level in sediments of eight reservoirs in the Cracow urban area (Bagry, Nowohucki, Plaszowski, Dabski, Przylasek Rusiecki, Tyniec, Zakrzowek, and Zeslawice Reservoirs), and assess its potential environmental risk with use of various criteria (Igeo - geo-accumulation index, CF - contamination factor, PLI - pollution load index, TEC/PEC - threshold effect concentration/probable effect concentration). Furthermore, the role of reservoir catchment for sediment contamination (agricultural, industrial, and urbanized) was studied. Also, levels of metal contamination were compared with other recreational reservoirs in Poland (Jeziorsko, Barycz Dzierzno Duze, Pogoria III, Rusalka, and Sloneczne Reservoirs). The study revealed considerable variation in the chemical composition of bottom sediments, evidently depended on their localization. Results showed that the sediments of the Cracow area reservoirs and from the other urbanized catchments were moderately contaminated. Reservoirs from industrial catchments had a considerably higher content level, while water bodies localized in agricultural areas displayed low content of heavy metals. According to Igeo and CF sediments of Cracow area reservoirs were mostly Cd contaminated. However, Cd contents were relatively high in urban (Sloneczne) and industrial areas (Dzierzno Duze). The same situation was found in PEC values exceedances. In other cases, investigated heavy metals were mostly between the TEC and PEC values, which indicate moderate contamination of the sediments and moderate impact on biota. Therefore, further research and monitoring of sediments quality should be maintained in future seasons due to the use of water reservoirs throughout the year for recreational purposes.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Fire safety is a major concern in the design of timber construction. Wood is combustible material. The thermal response of timber connections is usually the main fac tor in evaluating the overall load bearing capacity of wood structures exposed to fire . The analysis of timber joints under fire conditions is difficult and co mplex . Finite element model is developed to predict the thermal behav ior of bolted wood to wood joints exposed to fire. In fire, the material characteristic depend on the temperature. The thermal model is continuous, taking into account the thermal continu ity between the joint components. Also, the thermal model is used to predict the evolution of the temperature field inside the connection. The paper presents a summary of results from a numerical studies o f the fire behavior of wood to wo od timber connections with steel bolt. As a result of computer simulations the temperature distribution was obtained. During fire exposure, the timber section is reduced and steel bolt reduces strength. Load carrying capacity per shear plane in fire condit ions w as calculated using two methods : desi gn methods according to EN 1995-1-1 [5] and reduced l oad method according to EN 1995-1-2 [6] . In the first approach, the timber section loss and steel strength reduction during the fire were taken into account.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: The photophysical properties of donor-acceptor based benzoxazoles were investigated by means of steady-state and time-resolved fluorescence techniques. Additionally, laser stimulated second-order optical effects (preliminary second harmonic generation (SHG) were studied. The studies show that the nitro-benzoxazole derivatives decorated with different alkylo/arylo amino groups dissolved in medium polar aprotic solvents: tetrahydrofuran and butyl chloride, exhibit dual fluorescence from the locally excited state (1LE) and a highly polar charge transfer (CT) state. Ambient-temperature time-resolved fluorescence investigations prove the bimodal kinetics of the excited-state electron transfer reaction 1LE→1CT. The lack of any CT emissions in cyclohexane and highly polar acetonitrile is presumably due to an efficient inter-system crossing process or fast deactivation of a low-lying CT state. In addition, strong CT properties inspired us to check a possibility to vary the absorption of the first UV–Vis maxima under influence of the external bicolour coherent laser light and the related optical second harmonic generation (SHG). The two coherent beams of the infrared Er:glass laser at 1540 nm/770 nm formed gratings in the photopolymer solidified chromophore. The performed experiments are compared with the theoretically calculated electronic parameters within the B3LYP DFT approach. The presented data open novel type of materials, allowing to operate its transparency using external IR laser light in the near IR spectral range.]]>

rodzaj: materiały konferencyjne w książce
Abstrakt: The Samaipata or, more specifically, the Fuerte de Samaipata is a pre-Spanish archaeological site in Bolivia (since 1998 on the UNESCO World Heritage List). The main feature of the site is a natural rock which served as wak’a (a sacred place). Despite the strong dominance of the Incaic character, the site is multicultural and its origins date back to around 300 AD. Its current appearance is the result of at least 1200 years of cultural developments. At the end of the 20th century, the site was extensively studied and documented by German scholars. Recently, due to the threat of progressing erosion, a new project has been launched by a Polish team, whose main objective is to document the entire site with 3D laser scanning. The most distinguishing feature of the site is a complex arrangement of figural and geometrical petroglyphs, canals, and water reservoirs, as well as niches or entire rooms. The elements that attract less scholarly attention are long rows of small circular holes drilled into the rock. They are commonly associated with the vertical posts of quincha walls. However, there are doubts about the ability of the quincha wall to resist the extremely strong winds that can act on the top of the rock. Computer simulation is the proposed measure to clarify these reservations. The 3D model is based on the 3D laser scanning results, while FEM is used for solving structural analysis problems. Meteorological data and strength parameters of local wood species will provide supplementary data.]]>

Abstrakt: Contemporary world requires ecological solutions in motorization area, low energy consumption, safety and easy exploitation. The role of engineers and scientists is the realization and managing of the designing and exploitation processes within that area. The growing exploitation and ecological demands set successive challenges for constructors and scientists in the area of automobiles, powertrains and exploitation. Particularly essential is finding solutions decreasing fuel consumption and emission of the exhaust gases harmful components as well as application of the alternative powertrains such as hybrid and electric. The cyclical motorization conference KONMOT since 1976 is a place of meeting of outstanding scientists and engineers from country and abroad, raising contemporary problems of motorization with the possibility of publishing results on the international area. In 2018 automotive conference KONMOT organized celebrated the 42nd anniversary. It was organized by the Institute of Automobiles and Internal Combustion Engines in Cracow University of Technology (CUT). The first conference was held in Kroscienko-Szczawnica on 20-23 September 1976. The motto, that guided the deliberations, was "Progress in Research of Motor Vehicle." The conference was a nationwide and attended by many representatives of technical universities, research and development centres and plants related to the automotive industry. In the years 2000, 2004 and 2008, a conference was called KONMOT-AUTOPROGRES, the main organizer was the Cracow University of Technology. In 2002 and 2006 the main organizer of the conference was Automotive Industry Institute in Warsaw and the conference was called AUTOPROGRES-KONMOT. Papers presented on every two years conference KONMOT were published in the journal issued by the Polish Academy of Sciences “Portfolio of Science and the Problem Committee on Motorization” or published by the Technical Journal issued by CUT, as well as in the form of monographs. Some of the conferences were dedicated to the jubilee of work of outstanding scientific specialists in automotive area. Apart from the official agenda for the conference the gala dinners were organized for all participants, often headline performances by famous artists were important point of such meetings. The penultimate conference KONMOT was held on 22-23 September 2016 in Cracow under the slogan "Development of vehicles - construction, operation, ecology and safety." The organized scientific conference KONMOT-2018 as in previous years, provided an excellent opportunity to showcase of achievements of researchers and scientists and exchange of experience for a wide range of activity in research and development centres, industrial areas and universities. With regards to the current conference we are delighted to come up with one hundred sixty three (163) contributed research papers selected from the proceedings, as an output of the Scientific Conference KONMOT 2018 on Automotive Progress held in Cracow (Poland) from September 13-14, 2018. All papers were reviewed by two scientific researchers according to the requirements of IOP. This conference marks as previous meetings in a highly successful series of conference devoted to this important technical field. Conference KONMOT gathers industrial and scientific communities in the field design, experimental research and modelling of all scientific and industrial sectors of automotive branch. Contributions cover a wide range of topics including design and modelling of suspension, traction and new driving systems in automobiles, method of vehicles exploitation or tribology. A wide part of the conference was devoted to the electromobility as a new trend in transportation. New driving systems require new design of engines for better efficiency and lower exhaust gas emission. Most of the papers describe research, experimental investigations and modelling of combustion processes in internal combustion engines. The papers shown during KONMOT 2018 from both the oral presentation and poster sessions are included in this conference volume. They are divided into the following three topic areas: Design and Research of Automobiles, Exploitation of Automobiles and Internal Combustion Engines and Emission. More than one third of the papers are directly concerned with mathematical modelling and numerical simulation in automobiles and internal combustion engines. However, most of papers include experimental and industrial activity. Some of the papers concern applying of special new materials and were included in the Exploitation topic. The conference co-chairmen are grateful to the Scientific Committee and all the reviewers of the papers for their efficient work done in a very short period of time. These proceedings would not have been possible without the tremendous help of Mr Dr Eng. Marcin Noga and Mrs MSc Magdalena Kalarus from the Cracow University of Technology. Thanks also to The CUT Publishing House for preparing of special issue of conference abstracts. Finally, we would like to thank our sponsors for their financial support, without that the conference would not be so attractive for participants, such as Development and Research Centre BOSMAL in Bielsko-Biala, FEV Poland, EC Engineering, Horus-Energia and Polish Scientific Society of Combustion Engines (PTNSS) and others. The logos of our main sponsors are shown below. We invite all participants from whole the world to the next conference KONMOT 2020. ]]>
<![CDATA[The strength of wooden (timber)-glass beams combined with the polyurethane adhesive – DIC and Finite Element Analysis]]> Mon, 08 Oct 2018 08:41:49 +0200 Rodacki, Konrad; Zając, Bogusław; Kwiecień, Arkadiusz; Tekieli, Marcin; Furtak, Kazimierz
rodzaj: materiały konferencyjne w książce
Abstrakt: Results of tests on timber-glass composite I-beams with flexible polyurethane adhesive joining glass web and timber flanges together are presented in the paper. The carried out tests on these elements, tested cyclically and statically, manifested that this kind of adhesive is able to withstand over 100,000 cycles in fatigue tests without degradation. The following ultimate static test up to failure, made on semi-scale cyclically tested specimen, manifested the same characteristic as the static test up to failure done on the similar specimen without applied cycles. The tested transparent timber-glass composite I-beams shows also a suitable protecting factor against sudden failure, making such systems safe in exploitation in heritage structures, where visitors are present.]]>
<![CDATA[Between early-Christian architectural form and postminimalism]]> Mon, 08 Oct 2018 08:35:29 +0200 Podhalański, Bogusław
rodzaj: materiały konferencyjne w książce
Abstrakt: We are currently observing a growing interest in the early Christian writings of hermits, the great eulogists of Christ. In modern religious architecture the manifestation of this interest is a return to the simple forms of early Christian temples. The problem, however, is the quality of this architecture and how it is received by the public. New temples, minimalist in form, so eagerly promoted in architectural professional journals, which are mainly to the liking of critics and architects, are rejected by the faithful. Could the reason for this be the fact that emptiness is excessively exhibited in their interiors? Emptiness is a certain type of synonym for nothingness, and nothingness remains in contradiction with the main message of Christianity. Contrary to the almost unchanged canon of the orthodox temple, the architecture of Catholic churches sees strong protestant influence. In extreme cases this leads to a sort of elimination of decorative forms which have traditionally been present in Catholic churches. The postminimalism that appears in religious architecture refrains from completely contesting interior decoration. We are currently seeing a return to decorative forms, techniques like the fresco or the mosaic, which are treated architecturally, analogously to how they were treated in the beginnings of Christianity. Simplicity, however, should not be mistaken for simple-mindedness, which is why the demand for good Christian architecture and religious art is ceaselessly rising. The art of religious architecture, however, is based on the appropriateness of the architectural form in relation to the content that it expresses. The form of a church that is mistaken with the form of a discotheque should raise an eyebrow, especially that of its author, even when said author is a star of architecture.]]>
<![CDATA[Concurrent, coherent design of hardware and software embedded systems with higher degree of reliability and fault tolerant]]> Mon, 08 Oct 2018 08:18:43 +0200 Drabowski, Mieczysław
rodzaj: materiały konferencyjne w książce
Abstrakt: The paper includes a proposal of a new model of synthesis multiprocessors systems with higher degree of reliability. Optimal task scheduling and optimal partition at resources are basic problems in high-level synthesis of computer systems. Concept of reliability is a system idea that integrates hardware and software. Reliability is a feature of the system, which reflects the degree of user’s dependency to the system and is reflected in the continuity of actions of the equipment and installed programs. Achieving a higher degree of reliability of the system is implemented during the system operation, which limits damage caused by failures. This implementation is manifested by introducing internal control into the system, diagnostic of damaged components and using redundant modules, which allows tolerance of damage, achievement of the ability to soft fall and survival of the system. Concurrent, coherent and computer aided synthesis may have a practical application in developing tools for rapid prototyping of such systems.]]>
<![CDATA[Ecological Wall Systems as an Element of Sustainable Development - Cost Issues]]> Mon, 08 Oct 2018 08:02:15 +0200 Wojciech Drozd; Leśniak, Agnieszka
rodzaj: artykuł
Abstrakt: Building construction based on ecological, locally available, and slightly processed materials have a positive effect on the environment and local economy. Due to its simplicity, and thus possibility to erect a building on one’s own and using inexpensive materials, it may potentially become a solution to satisfy the continuously growing demand for residential buildings. In the paper, three variants of ecological external walls were proposed: a wall made of clay blocks insulated with mineral wool boards; a wall made of clay compacted in formwork insulated with mineral wool boards; and a wooden frame structure filled with straw bales and cladded with fiberboards. The layers of the walls were chosen in such a manner that the heat transfer coefficient values for the studied variants are as equal as possible (0.2 W/m2K), thus allowing for a reliable comparative study. The cost calculation of each variant of walls construction was made. The obtained results allow selection of a more advantageous solution.]]>

Abstrakt: Introduction ACL injuries – next to damage to the collateral ligaments, menisci of the knee – are the most common injuries of the knee joint and very often require surgical treatment. The main aim of the treatment is to restore normal gait pattern. The objective of this study was to determine the influence of reconstructed ACL on selected gait parameters by using an accelerometer system. Material and methods The study involved 34 people aged 18-54 who were divided in two groups. The first group consisted of 20 people after ACL reconstruction, aged 19-54 years old (mean 29). The second group consisted of 14 healthy people between the age of 18-45 (mean 25.36). Gait analysis in normal and fast rate was performed using the CQMotion Electronik System, MEMS type. Results Differences in the results were observed in the first group. In 75% of people during normal walking and in 95% during fast walking, a 5% difference between the healthy limb and the limb after ACL reconstruction was observed. The gait rate had influence on acceleration value which was observed in RMS values in both of the groups. The RMS value was different, depending on the gait rate. Conclusions Accelerometric gait analysis shows that the differences in comparing rate values between limbs are not so great, however, the gait pace has influence on some gait parameters. parameters.]]>
<![CDATA[The Response Surface Methodology revisited - comparison of analytical and non-parametric approaches]]> Sat, 06 Oct 2018 12:09:42 +0200 Osocha, Przemysław; Podgórski, Jordan
rodzaj: artykuł w czasopiśmie
Abstrakt: Since G.E.P. Box introduced central composite designs in early fifties of 20th century, the classic design of experiments (DoE) utilizes response surface models (RSM), however usually limited to the simple form of low-degree polynomials. In the case of small size datasets, the conformity with the normal distribution has very weak reliability and it leads to very uncertain assessment of a parameter statistical significance. The bootstrap approach appears to be better solution than – theoretically proved but only asymptotically equal – t distribution based evaluation. The authors presents the comparison of the RSM model evaluated by a classic method and bootstrap approach. ]]>
<![CDATA[The outline of the expert system for the design of experiment]]> Sat, 06 Oct 2018 12:00:53 +0200 Dwornicka, Renata; Pietraszek, Jacek
rodzaj: artykuł w czasopiśmie
Abstrakt: The design of experiment (DoE) is a methodology originated from early 1920s when Fisher’s papers created the analysis of varian ce and first known experimental d esigns: latin squares. It is focused on a construction of empirical models based on measurements obtain ed from specifically structured and driven experiments. Its development resulted in the constitutio n of four distinctive branches recognized by the industry: factorials (full or fractional), Taguchi ’s robust design, Shainin’s Red-X ® and a response surface methodology (RSM). On one hand, the well-known success stories of this methodology implementations promise great benefits, while on other ha nd, the mathematical complexity of mathematical and statistical assumptions very often lead to imp roper use and wrong inferences. The possible solution to avoid such m istakes is the expert system s upporting the design of experiments and subsequently the a nalysis of obtained data. The authors pro pose the outline of such system and provides the general analysis of the ontology and related infer ence rules.]]>
<![CDATA[Natural frequencies of rectangular laminated plates - Introduction to optimal design in aeroelastic problems]]> Sat, 06 Oct 2018 10:51:11 +0200 Muc, Aleksander
rodzaj: artykuł w czasopiśmie
Abstrakt: Free vibration (or eigenvalue analysis) is a prerequisite for aeroelastic analysis. For divergence analysis, slope influence coefficients (rotation at point i due to unit load at point j) are calculated using free vibration mode shapes and corresponding frequencies. The lowest eigenvalue is of interest and gives the divergence speed. The present paper considers the maximization problem of eigenfrequencies for composite panels. The influence of boundary conditions and constant or variable stiffnesses on optimization results are investigated herein. A new convenient set of design variables is employed in the analysis. The computations are carried out with the use of the Rayleigh–Ritz method and Finite Element analysis (2D quadrilateral and 3D solid elements).]]>
<![CDATA[The analysis of applying CVT gear ratio rate control for scooter efficiency improvement]]> Sat, 06 Oct 2018 10:33:54 +0200 Grzegożek, W.; Szczepka, M.; Kot, Adam
rodzaj: artykuł w czasopiśmie
Abstrakt: Continuously variable transmissions (CVTs) potentially ensure the selection of such a gear ratio that scooter fuel consumption can reach a minimum value. Traditionally, scooter CVT gearboxes are mechanically controlled, causing a gear ratio to be an engine revs function. This solution does not ensure optimum gear ratio. In this paper, the solution for fuel optimal control problem is presented. The results, obtained during brake stand tests of scooter powertrains, show the significant values of brake specific fuel consumption for the velocity that is maximum for a scooter (as stated in The Highway Code). With the introduction of a CVT gearbox, in which the selection of gear ratio can be controlled according to the worked out strategy, the solution for fuel consumption problem is found. Electromechanical actuators ensure the selection of a gear ratio independently of engine revs. Such type of construction solution makes working out the suitable control strategy, which ensures decreasing of scooter fuel consumption, possible. Presented strategies do not use precise optimization techniques. The CVT efficiency has a strong influence on a transient operation. In the paper, the control strategy that results in fuel consumption decrease of over 15% is presented. The strategy was worked by fuel consumption map for a defined scooter exploitation model. The ways of realization of the worked out strategy were tested on the brake test stand. ]]>
