rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: The article presents the results of thermal and flow analysis of the working conditions of neighbouring waterwall tubes, loaded with heat streams of different values. The numerical model used for the analysis, allowing to calculate the temperature distribution of the tubes and the fluid flowing through them at each time step depending on the thermophysical parameters of the fluid and the material from which the tubes were made. By using the algorithm it is possible to precisely determine the temperature distribution for tubes, allowing to determine the places where the most divergent temperatures occur and in which thermal stresses of the highest value may occur. Analysis for several adjacent tubes will allow for the effect of temperature differences in the tubes to the temperature of the fin which is connecting them and to collect data that may be used for the determination of stress distribution in the tubes and fins.]]>
<![CDATA[Competitions with local partnerships as a teaching mode to develop students’ learning]]> Wed, 20 Nov 2019 09:13:28 +0100 Wdowiarz-Bilska, Matylda
rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: A flexible approach to teaching is discussed in this article. The method of teaching outlined is one in which competition becomes a means of measurement. This departure from the norm in teaching was implemented as a part of urban design module classes, taught during the sixth semester of the first tier of studies. The classes were taught in the form of an international student competition with representatives of the business sector, as well as the local government of the city of Bochnia, in southern Poland. Students who participated in it developed their teamwork skills and the ability to dynamically react to change. Awareness of the utility and usefulness of their work is important for the development of students, as is preparing them for their professional lives. Exposure to the teaching methods described here was found to stimulate the development of students’ creativity in design.]]>
<![CDATA[Innovative teaching of spatial planning at Cracow University of Technology]]> Wed, 20 Nov 2019 09:11:15 +0100 Węcławowicz-Bilska, Elżbieta
rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: At Cracow University of Technology (CUT) spatial planning is taught in the Faculty of Architecture (FA) and in the Inter-faculty Spatial Management Study Course (IFSMSC), as well as in postgraduate studies. The innovative teaching system involves integrated module assignments, a specified order of teaching and group work. The teaching of spatial planning is in line with the holistic view of the city, with particular emphasis on environmental conditions. These issues are taught at the FA as specialist classes and lectures, such as ecology and environmental protection and regional planning. Environmental planning, regional policy, urban development and environmental protection, as well as specialist issues concerning transport and municipal economy are taught in the IFSMSC. The possibility of continuing education is an important element of the teaching.]]>
<![CDATA[New educational programmes as a factor in forming students’ innovative competencies]]> Wed, 20 Nov 2019 09:08:51 +0100 Semenyuk, Olga; Kuc, Sabina; Sadykova, Sara; Arynov, Kaldybay; Beloussova, Ella; Niyazbekova, Shakizada; Suleimenova, Buldyryk

Abstrakt: The main reason for creating new educational programmes is to produce highly qualified graduates from university-level institutions to meet demand in the workplace. These experimental programmes enable students to be trained in professional skills, while exposing them to the latest technologies, and the practice of that knowledge through universal standards and reality. The graduates also develop an outlook, which contributes to their gaining professional experience within design organisations and public institutions. In today’s rapidly changing labour market, graduates must be provided with innovative knowledge that enables adaptation to new technologies. Labour market studies indicate a deficiency in highly qualified specialists in areas where interdisciplinary competencies and a broader range of knowledge is required. The fostering of competencies, such as creative thinking, an active stance in life and a creative and analytical approach are significant in enabling students to solve problems in the professional sphere. Educational programmes must adapt to the demand of the global market.]]>
<![CDATA[Development of eco-architecture in Kazakhstan is gaining ground]]> Wed, 20 Nov 2019 08:40:49 +0100 Semeniuk, Olga; Kuc, Sabina
rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: People are a part of nature. Therefore, in creating a comfortable and surrounding space, balance and harmony with nature must be maintained. Eco-architecture is directed toward the organisation of social processes in the urban environment, so as to improve the environment; to a dialogue with nature and with the local cultural and historical heritage. Eco-architecture requires as much application as possible of renewables and, at a minimum, the adoption of traditional energy resources. Architectural projects in which there is use of natural solar and wind energy are becoming ever more popular. Eco-architecture is an indicator not only of the spiritual, but also the economic condition of society. It develops together with the economy. A shortage of traditional power sources requires the development of new tendencies in modern architecture. This means the use of alternative power sources, economic heat-insulating materials, and new lighting systems. In this article, the authors examine the green building trend gaining ground in Kazakhstan.]]>
<![CDATA[Transition from n50 to actual air exchange dependent on climatic conditions]]> Thu, 14 Nov 2019 14:12:48 +0100 Kisilewicz, Tomasz; Nowak-Dzieszko, Katarzyna; Rojewska-Warchał, Małgorzata
rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: The knowledge of the air flow and air exchange in the building is critical both on the design and operation stage of the building. Infiltration of air interferes with the mechanical ventilation and determines the proper functioning of the natural ventilation system, still commonly used in the standard buildings. The building airtightness can be described by n50 parameter, however it does not specify the real air exchange in natural conditions. According to the simple procedure of the standard EN ISO 13789, factor n50 may be easily converted to the monthly averaged air change rate. However, it is difficult to accept the same value of air change rate in any month of a year, as it is often done in the certification procedures. More precise, climate dependent conversion procedures have been elaborated in USA, but they were developed for the specific local building technology and local climate conditions. This paper presents the results of the preliminary measurements conducted in a single family house in Poland, built in a heavy-weight technology. The real air exchange rate was measured in various climatic conditions by means of gas tracing method, with CO2 as the tracer gas, in order to prove a relationship between the enhanced procedure and the external conditions. Acceptable agreement between the results of the measurement and model calculations was obtained. Based on the preliminary results, the authors determined the more realistic influence of the enhanced algorithm on the ventilation energy demand. The use of the simplified model resulted in case of the analyzed object in 15% overestimation of the ventilation thermal losses.]]>
<![CDATA[Influence of building airtightness on the internal thermal comfort and air quality in the single family house]]> Thu, 14 Nov 2019 14:05:35 +0100 Kisilewicz, T.; Nowak-Dzieszko, K.; Rojewska-Warchał, M.

Abstrakt: The knowledge of the air exchange and building air-tightness is an indispensable source of information, both on the design and operation stage of the building use. Properly functioning ventilation system affects significantly internal thermal comfort and internal air quality. Infiltration of air determines the proper functioning of the gravitational ventilation, still the most commonly used system in Polish single-family housing. However, the most popular and easy to measure parameter: building airtightness (n50), does not specify the real air exchange in the actual climatic conditions. The real air flow rate may be determined with much more troublesome gas tracing method. Air flow rate, n, is in this method obtained from the decaying curve of gas concentration after injection of tracer gas into the building. This paper presents the results of the airtightness measurements conducted in a single family house with natural ventilation. Both, n50 parameter and building air flow rate n have been measured. The results of the measurements were used as a model calibration tool in the annual computational simulations carried out in the Design Builder program for the Polish climatic conditions. Based on these simulations the authors determined the influence of building airtightness on the internal thermal comfort and the potential scenario of its control.]]>
<![CDATA[Details of Krakow’s modernist townhouses]]> Thu, 14 Nov 2019 12:39:35 +0100 Makowska, Beata
rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: The aim of this paper is to present the key features of façade details typical for townhouses erected in Krakow in the period 1918-1939. It emphasizes the importance of the townhouse details for Krakow's cultural heritage and the pressing need to document them. Since the funds of the Social Committee for the Renovation of Krakow's Monuments are allocated in the first priority to overhauls of public utility buildings and registered monuments, the modernist buildings have little, if any, chances for renovation. Meanwhile, they continue to fall into disrepair, which makes the documentation efforts even more urgent. Only a few most precious buildings from the interwar period are listed in the register of monuments. The remaining ones are not awarded by appropriate legal protection. Based on the analysis of the influences of a variety of trends on the development of Krakow's townhouse façades and their details in the period 1918-1939, three basic groups of façades were identified. The first one relied on the historic style, the second, and most numerous one, combined historic and functionalist forms, while the third one emerged under explicit influence of functionalism. Key elements of the historic stylistics include: symmetry and division of the façade into three parts (bossage on the wall base, vertically articulated main part, finial), strong emphasis on the entrance portal, conspicuous cornices and decorations. In townhouses combining historic and functional forms, the prevailing stylistic elements include simple poles, lesenes (often worked in the plaster texture), enhanced with decorations (coats of arms, friezes, etc.). The ornamental-stylistic current typical of the 'Krakow school' comes in several different iterations. Few townhouses were explicitly influenced by the European functionalism. Designers aimed at simplifying the detail forms and their geometrization, producing an effect that revealed more deeply the functional content of the mass. The functionalist current in Krakow differed artistically from the avant-garde European projects. Nonetheless, it shared similar rationalist objectives – usability, economy and simplicity. Façade details often served as a link between contemporaneity and previous periods; they took account of features typical of the Krakow's historic architecture.]]>
<![CDATA[CitAgra: the compact city with integrated agriculture and ecology]]> Thu, 14 Nov 2019 12:36:44 +0100 Jelenski, Tomasz
rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: The growing problem of urban sprawl – low-density, fragmented, car-dependent development on greenfields – is increasingly serious for both Europe and the rest of the world. It brings with it a number of negative consequences for human health, well-being, social and economic performance, and negative ecological impacts, including emissions, which contribute to climate change. Therefore, in order to improve urban quality of life and address the “20-20-20 strategy” of global objectives, we propose a series of pilot projects that introduce significant planning, managerial and technology initiatives combined to enhance cooperation between European citizens and experts. To increase the extent and health of urban cultivation and maximize the benefits of an urban canopy, cities need an integrated approach and innovations from city planners, engineers, and landscape architects, as well as citizen advocacy and participation along the lines of public-private partnerships. We presume that even if various actors share a common vision, it needs more knowledge for maximum benefits to develop. Our thesis is that urban cultivation can play a significant role as a catalyst for socio-economic sustainability. Comparing benefits from urban forest and agrarian functions, which in many places would compete for the same space, would be necessary. There is now an increasing body of knowledge that several measures of high urban density – including residential, retail, and service density, street-intersection density, and land-use diversity – might have important public health consequences. With more evidence, one can plan neighbourhoods that are more compact and more attractive (thanks to activity-influencing factors such as local services, public transport, leisure, agrarian activities and more), halt invasive sprawl, promote physical activity and social interaction, and shield from environmental and social negatives, such as pollution and feeling unsafe. In this project, the Nature-Based Solutions concept will be applied to improve the impact on quality of life. In this sense, CitAgra would leverage the EU agenda by making the project a form of pilot implementation.]]>
<![CDATA[Detection of Cosmic-Ray Ensembles with CREDO]]> Thu, 14 Nov 2019 12:32:47 +0100 Woźniak, Krzysztof W.; Niedźwiecki, M.; Smelcerz, K.
rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: One of the main objectives of cosmic-ray studies are precise measurements of the energy and chemical composition of particles with extreme energies. Large and sophisticated detectors are used to find events seen as showers starting in the Earth's atmosphere with recorded energies larger than 100 EeV. However, a Cosmic-Ray Ensemble (CRE) developing before reaching the Earth as a bunch of correlated particles may spread over larger areas and requires an extended set of detectors to be discovered. The Cosmic-Ray Extremely Distributed Observatory (CREDO) is a solution to find such phenomena. Even simple detectors measuring the particle arrival time only are useful in this approach, as they are sufficient both to provide candidate CRE events and to determine the direction from which they are arriving.]]>
<![CDATA[Optimization of kinematic errors model used in virtual CMM systems]]> Wed, 13 Nov 2019 13:23:16 +0100 Gąska, A.; Harmatys, W.; Gąska, P.; Gruza, M.; Ostrowska, K.; Sładek, J.

Abstrakt: The kinematic errors are one of the main contributors of coordinate measurement total error and should be taken into consideration during preparation of virtual CMM (VCMM) models. Modules responsible for simulation of kinematic errors that were used so far required long lasting experiments to be performed before implementation of VCMM. It was one of the biggest limitations regarding its usage. The optimization method for kinematic error model was proposed in this paper. Its usage resulted in reduction of duration of implementation experiments more than 4 times.]]>
<![CDATA[Reliability and availability assessment of a transport system using Dynamic Fault Tree and Monte Carlo simulation]]> Wed, 13 Nov 2019 12:54:55 +0100 Szkoda, Maciej; Kaczor, Grzegorz; Satora, Magdalena
rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: Ensuring a high level of reliability of the transport system is one of the most important issues related to the proper functioning of this system. It is concerned with the delivery of the transported goods on time and in accordance with recipient's order specification. The means of transport used in the delivery process are exposed to many external factors that may affect the reliability and safety of supply. Therefore, modelling and assessing the reliability of these systems requires the use of appropriate calculation methods that take into account complex scenarios reflecting the conditions of actual operation and maintenance. The presented paper concerns the application of Dynamic Fault Tree (DFT) together with Monte Carlo simulation to assess the selected reliability and availability indicators for the given transport system. The assessment of reliability was done based on the typical probabilistic models for analysis of the time to failure and the time to repair assigned to the selected components. The proposed approach allows detecting the weakest components of the transport system and is the basis for the development of preventive maintenance tasks. The presented model of the transport system can be further developed and adapted to needs of the specific system.]]>
<![CDATA[Comparison of different interpolation methods, used for modelling of probe heads errors]]> Tue, 12 Nov 2019 12:44:21 +0100 Gąska, P.; Gruza, M.; Gąska, A.; Harmatys, W.; Sładek, J.

Abstrakt: Virtual CMMs allow user to estimate the uncertainty of measurement using multiple measurement simulations. Most often the Virtual CMMs consist of several modules responsible for main errors sources modelling. These modules utilizes different interpolation methods in order to model the error values in any point in machine's measuring volume. Thus the proper function ing of Virtual CMM depends on chosen interpolation method. Experiment described in this paper is aimed to assess which interpolation method would give the best results for newly developed probe head errors model for the articulated probe heads.]]>
<![CDATA[The ITER radial neutron camera in-port system: Nuclear analyses in support of its design development]]> Fri, 08 Nov 2019 12:25:48 +0100 Moro, Fabio; Esposito, Basilio; Marocco, Daniele; Podda, Salvatore; Pompili, Fulvio; Riva, Marco; Flammini, Davide; Colangeli, Andrea; Kantor, Ryszard
rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: The ITER Radial Neutron Camera (RNC) is a multichannel detection system hosted in the Equatorial Port Plug 1 (EPP 1). It is designed to measure the uncollided neutron flux from the plasma, providing information on the neutron emissivity profile and total strength. The RNC structure consists of two sub-systems based on fan-shaped arrays of cylindrical collimators: the ex-port system, covering the plasma core with 2 sets of lines of sight lying on different toroidal planes, and the in-port system, enclosed in a dedicated cassette within the EPP1 diagnostic shielding module, for the measurement of neutrons generated in the plasma edge. Due to the harsh environment in which it has to operate, the design of the in-port RNC system is particularly critical both from the measurements point of view (low signal to noise ratio induced by the high level of scattered neutrons at the detector positions) and from the structural point of view. The paper presents the results of the neutronic analyses performed with the MCNP Monte Carlo code with the aim of optimizing the in-port RNC design in order to enhance the diagnostic measurement performance and evaluating the nuclear loads that have to be withstand by its structural elements, detectors and associated components.]]>
<![CDATA[Zrównoważona forma urbanistyczna: kształtowanie przestrzeni publicznej]]> Thu, 07 Nov 2019 14:00:51 +0100 Jeleński, Tomasz
rodzaj: materiały konferencyjne w czasopiśmie
Abstrakt: Jedną z najważniejszych idei współczesnej urbanistyki jest osiągnięcie równowagi pomiędzy środowiskami siedzib ludzkich a środowiskiem naturalnym. Wymaga to odnawiania zdegradowanej substancji miejskiej oraz konserwacji zasobów naturalnych z poszanowaniem czynników ekonomicznych. Dla ożywienia oraz praktycznego i emocjonalnego związania urbanistyki, architektury krajobrazu i planowania, potrzebujemy holistycznego ujęcia problemów ekologii i urbanizacji, oraz odrzucenia binarnych opozycji takich jak architektura i natura. Inicjatywy trwałego rozwoju i przedsięwzięcia planistyczne powinny równocześnie sprzyjać tworzeniu bardziej zwartych i przyjaznych pieszym miast, odtwarzaniu bogactwa miejskich ekosystemów i niwelowaniu różnic socjalnych. Powinniśmy przełamać nieuzasadnione podziały między nauką i sztuką, bo praca badawcza i intuicja mogą, i powinny w symbiozie służyć projektowaniu środowiska.To jest warunek naszej artystycznej i zawodowej integralności, ale także trwałości i piękna środowiska, które tworzymy. Wzajemne przenikanie dyscyplin, łączenie działań w różnych skalach, może umożliwić sprawne rozwijanie zrównoważonych socjalnie i kulturowo przestrzeni publicznych.]]>
