rodzaj: materiały konferencyjne w książce
Abstrakt: The original placemaking philosophy was based on the recognition that place is intrinsically tied to cultural values, ones tested by generations of human interaction. Its practices have created a growing body of knowledge of the design strategies and physical elements that make vital public spaces and successful development projects. However, without proper consideration of local history and heritage, such practices might not leave room for character and distinctive beauty. The result can be places that are again more a manifestation of planning principles and generalised design strategies than integrating urban cultures and communities. Without the inclusion of the attributes that people want to preserve, adapt, rehabilitate, or even reconstruct, public space may present a missed opportunity to produce specific, beautiful places. Careful approaches to existing structures provide a sense of continuity, comprehensibility, meaningfulness, and coherence – the values of importance beyond aesthetic satisfaction. Placemaking practices might be expanded again, to advocate for more sustaining, organised complexity, and reconciling new urban communities with adaptive places full of character.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Problems with parking individual cars, particularly in urban areas, were already experienced by the inhabitants of developed countries in the interwar period. These problems continue to appear, as the number of cars increases and there are fewer and fewer parking spaces. Therefore, solutions are sought after to ensure the largest possible number of parking spaces with the smallest occupied area, especially in large agglomerations of highly developed countries. The article presents one of the possible solutions – rotary car parks (The Rotary Automated Car Parking System; RACPS). The research results reffered to in the article are the effect of works conducted at the Faculty of Mechanical Engineering of the Cracow University of Technology in the field of modelling and optimisation of a rotary car park [5, 6, 8].]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Kolektory słoneczne są głównymi elementami solarnych systemów grzewczych. Praca tych urządzeń polega na konwersji energii promieniowania słonecznego na ciepło czynnika roboczego. Czynnikiem tym może być zarówno ciecz (glikol lub woda), jak i gaz (powietrze). Ze względu na konstrukcję wyróżnia się kolektory płaskie, próżniowe, próżniowo-rurowe i skupiające. Kolektory płaskie są stosowane przede wszystkim w budynkach, w których potrzeby cieplne są niskie lub średnie, czyli na przykład w gospodarstwach domowych. Rozwój kolektorów został ukierunkowany na zwiększenia wydajności oraz poprawy efektywności ekonomicznej inwestycji. W artykule oceniono wpływ zmiany powierzchni płaskich kolektorów słonecznych na opłacalność ekonomiczną inwestycji. Do analizy wytypowano dom jednorodzinny, zlokalizowany w województwie małopolskim, w którym instalacja przygotowania ciepłej wody użytkowej została rozbudowana o system solarny. System ten składa się z płaskich kolektorów, o łącznej powierzchni absorberów 5,61 m2. Jako czynnik roboczy w instalacji stosowany jest glikol. W celu poprawy efektu ekonomicznego zaproponowano zwiększenie powierzchni absorberów. Na podstawie trzyletnich pomiarów nasłonecznienia oraz efektów cieplnych instalacji, stworzono model ekonomiczny służący do oceny opłacalności zwiększenia powierzchni kolektorów słonecznych. Obliczenia z użyciem modelu promieniowania HDKR wykonano w środowisku Matlab dla lokalizacji Tarnów (najbliższej instalacji). Ponadto na podstawie rzeczywistych pomiarów z tej instalacji, odzwierciedlających wpływ wielu niemierzalnych czynników na efektywność przetwarzania energii słonecznej, wykonano symulacje efektu ekonomicznego dla różnych wielkości zapotrzebowania na ciepło. Otrzymane wyniki uogólniono, co daje możliwość ich wykorzystania w procesie doboru wielkości powierzchni kolektorów w przypadku podobnych instalacji]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: The problems discussed in the present paper are well-known both from the theoretical (numerical) and experimental point of view. The novelty of our approach depends on the application of hybrid experimental methods and a comparison of their effectiveness in the description of complicated fatigue problems arising in the analysis of the behavior of laminated panels with open holes and subjected to tensile loading. Three experimental methods were used: infrared thermography (passive), structural health monitoring (active), and digital image correlation. The experimental investigations were supplemented by the finite element description of the problem dealing mainly with the static behavior, monitoring the development and final fracture of composites. The considerations concern laminated panels oriented at ±45° with different types of holes, i.e., vertical elliptical, horizontal elliptical, and circular.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: A two-dimensional Lennard-Jones system in a circular and rotating container has been studied by means of molecular dynamics technique. A nonequilibrium transition to the rotating stage has been detected in a delayed time since an instant switching of the frame rotation. This transition is attributed to the increase of the density at the wall because of the centrifugal force. At the same time the phase transition occurs, the inner system changes its configuration of the solid-state type into the liquid type. Impact of angular frequency and molecular roughness on the transport properties of the nonrotating and rotating systems is analyzed.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: We study algebraic properties of Poisson brackets on non-associative non-commutative algebras, compatible with their multiplicative structure. Special attention is paid to the Poisson brackets of the Lie-Poisson type, related with the special Lie-structures on the differential-topological torus and brane algebras, generalizing those studied before by Novikov-Balinsky and Gelfand-Dorfman. Illustrative examples of Lie and Balinsky-Novikov algebras are discussed in detail. The non-associative structures (induced by derivation and endomorphism) of commutative algebras related to Lie and Balinsky-Novikov algebras are described in depth.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: The quest for a sustainable built environment brought dramatic changes to architectural design because of the integrated design process. The integrated design process is the modern way to realize ‘‘performance architecture,’’ that is, design with a view to field performance. Integrated design process permits merging of concepts from passivehouse designs, solar engineering, and an integration of the building enclosure with mechanical services. In part 1 of this series, the emergence of many new multi-functional materials was discussed. Yet, current innovation is guided by lessons from history. Thermal mass in heavy masonry buildings allowed periodic heating. The authors postulate integration of a hydronic heating system with the walls and the use of smart temperature control of the heating system to modify and optimize the thermal mass contribution. To use the mass of a building, one must accept transient temperature conditions where the indoor temperature varies but is confined by comfort requirements for both summer and winter conditions. On the other side, resiliency requirements dictate that in the absence of electricity the air temperature does not fall below about 12C over a period of several hours. This requirement implies that summer cooling will likely be separated from the heating systems and that operation of a low-energy building is heavily dependent on the design of smart control systems. Analysis of control systems provided in this article for earth-to-air heat exchangers and cooling of houses with lightweight walls lead us to the requirements of separation between heating and ventilation and needs for different sources of fresh air. Finally, a new concept emerges.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: The objective of the research was to look into the role that bioretention systems play in a decentralized management of stormwater runoff from the impervious areas. The study took place at a catchment of a low permeability and equipped with a combined sewer system. Two rainfall options were selected: actual rainfall intensity q = 105.65 dm3∙s–1∙ha–1 and a hypothetic rainfall with a probability of exceedance p = 10% and q = 40.7 dm3∙s–1∙ha–1. All calculations were carried out using the SWMM EPA program (storm water management model; Environmental Protection Agency). They have shown that the bioretention system reduces the cumulative flow rates by over 55% and the flood wave volume by over 54%. Moreover, it was found that, a precipitation pattern significantly influences runoff from the urban catchment]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: The presented research shows the results of matrix-assisted laser desorption/ionization mass spectrometry, which was used as a means of monitoring the synthesis of novel high-molecular weight epoxy resins. The products were obtained by the reaction of epoxidized soybean oil (ESBO) and bisphenol A (BPA), using a modern and pro-ecological modification of the well-known method of the synthesis of epoxy resins, called “the epoxy fusion process”. On the basis of the obtained spectrograms, the manner in which substrates reacted with each other during the conducted synthesis was determined. Initially, after the reaction of the oxirane group of ESBO with the hydroxyl group of BPA, subsequent reactions occurred, involving other molecules of bisphenol and the remaining oxirane rings of epoxidized vegetable oil or the reaction of a free phenolic group with the following macromolecule of modified oil. It was found that the final product of the polyaddition (ESBO_BPA), obtained by the epoxy fusion process conducted in bulk, consists of macromolecules with various structure. First, smaller oligomers such as 1ESBO + 1BPA and ESBO + 2BPA were formed, and as the reaction proceeded, they rapidly reacted with each other forming larger macromolecules: 2ESBO + 2BPA, ESBO + 3BPA, 2ESBO + 3BPA, 3ESBO + 3BPA, and 3ESBO + 4BPA. On the basis of the course of the ESBO_BPA polyaddition process in the registered m/z range, it was found that 1ESBO + 1BPA tends to react with other substrates from the reacting mixture to create a linear product. Bisphenol A is a rigid element, which connects the elastic alkyl chains of epoxidized soybean oil in the obtained macromolecule.]]>
<![CDATA[Practices of built heritage post-disaster reconstruction for resilient cities]]> Thu, 19 Apr 2018 14:49:34 +0200 Jeleński, Tomasz
rodzaj: artykuł w czasopiśmie
Abstrakt: The concept of resilience has become increasingly important to our understanding of sustainable planning. Post-disaster urban and architectural reconstruction might be treated as a strategy for resilient cities, helping them to reinvent themselves after possible destruction. The purpose of this study is to analyse several cases of nearly total reconstruction of historical urban complexes. Specifically, it explores how urban heritage conservation and recreation could contribute to the resilience agenda, giving traumatised societies a sense of continuity and localness. It analyses the changes in the conservation doctrine, highlighting the growing acceptance of architectural reconstructions. Drawing on historical examples, mainly derived from the Polish School of Conservation practice, this paper argues that the methods and processes attempted to regain identity for the thoroughly rebuilt structures proved effective in recreating the identity of such cities as Kalisz, Warsaw, Gdańsk, and Wrocław. The article argues that while processes at the governmental level emphasised the strengthening of national identity, the experiences of the reconstructed townscapes eventually involved forms of more diverse municipal identities. The article highlights that the strategy of recreating traditional images of cities after their mutilation in disastrous events might be a key to becoming a more resilient city and the formation of the post-disaster citizenry.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Similarly to any other industry, the construction sector puts emphasis on innovativeness, unconventional thinking, and alternative ideas. At present, when sustainable development, ecology, and awareness of people’s impact on the environment grow in importance, low impact buildings can become an innovative alternative construction technology for the highly industrialized construction sector. ,e paper presents a comparative study of three walls made of available materials used locally, which can be classified as biosourced materials, in terms of construction time. ,e comparison of times necessary to make 1m2 of the wall allows us to decide which building technology is more advantageous in terms of the construction duration. A shorter construction time means lower labour costs and lower expenses for construction machines. In order to obtain answers to the questions posed, the authors made extensive searches of source data on the time-consuming building works which used locally sourced materials. Reference is made to “Temporary principles of erecting clay buildings” issued by the Institute of Housing Construction in Warsaw (Poland). ,ree types of walls made of locally sourced materials were studied: a wall made of clay blocks insulated with mineral wool boards, a wall made of clay compacted in formwork, and one insulated with mineral wool boards and wooden frame structure filled with straw bales and cladded with fibreboards. ,e layers have been chosen in such a manner that heat transfer coefficient values for the studied variants are as equal as possible (0.2W/m2 K), thus allowing a reliable comparative study.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Superheaters are high-temperature cross-flow heat exchangers. Steam flows inside the tubes, and the flue gas outside in a direction perpendicular to the axes of the tubes. However, they differ very substantially from the other heat exchangers operating at low temperatures because of the high dependence of steam heat capacity on temperature and radiation heat transfer on the flue gas side. Also, the flow tube arrangement is usually complicated. Due to the work of superheaters in a harsh environment, they are prone to damage. About 40% of the emergency shutdowns of boilers are caused by overheating of the tube material which in turn causes them to break. The paper presents the mathematical model of the superheater. The finite difference model with distributed parameters is based on the solution of energy conservation equations for steam, tube wall, and flue gas. TheCFDsuperheater modelwasalsodevelopedtoverifythe finite-differencemodel.Themodeldevelopedinthe paper can be used to assess the fouling degree of the superheater tubes by ash. ]]>

rodzaj: artykuł
Abstrakt: The production of chemicals from biomass is a very challenging process due to its diverse chemical composition. Lignin, cellulose and hemicellulose are the three main biopolymers of wood biomass, with cell walls of plant origin. Lignin has been chosen for the present studies due to its range of different linkages and structures. The present work involved a computational study of the most dominant lignin dimers and their vibrational structures, based on the Density Functional Theory method. Full geometry optimization of the compartments used the StoBe code with cluster model and non-local functional (RPBE) approach. The calculations of the vibrational frequencies were performed with harmonic approximations as well as an anharmonicity fit in the Morse potential function, as implemented in the StoBe code. In the case of lignin, the calculations included three different precursors based on: coumaryl alcohol, coniferyl alcohol and sinapyl alcohol. To represent the cellulose and hemicellulose derivatives, selected aldopentoses and aldohexoses (arabinose, xylose, glucose, galactose, and mannose) were considered. Presented here are the theoretical investigations for a variety of biomass derived compounds, to give the possibility of obtaining a theoretical VBD (Vibrations Basis Database) for experimental spectra interpretation. Such a database could be further used in the preliminary composition assessment of biomass derived substrates, which will be discussed here in more detail.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: The quest for a sustainable built environment has resulted in dramatic changes in the process of residential construction. The new concepts of an integrated design team, building information modeling, commissioning of the building enclosure, and passive house standards have reached maturity. Global work on development of new construction materials has not changed, but their evaluation is not the same as in the past when each material was considered on its own merits. Today, we look at the performance of a building as a system and on the material as a contributor to this system. The series of white papers—a research overview in building physics undertaken in European and North American researchers—is to provide understanding of the process of design and construction for sustainable built environment that involves harmony between different aspects of the environment, society, and economy. Yet, the building physics is changing. It merges with building science in the quest of predicting building performance, it merges concepts of passive houses with solar engineering and integrates building shell with mechanical services, but is still missing an overall vision. Physics does not tell us how to integrate people with their environment. The authors propose a new term buildings with environmental quality management because the vision of the building design must be re-directed toward people. In doing so, the building physics will automatically include durability of the shell, energy efficiency, and carbon emission and aspects such as individual ventilation and indoor climate control. This article, which is part 1 of a series, deals with materials, and other issues will be discussed in following papers.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Applicability of 15 trivalent samarium complexes as novel luminescent probes for monitoring progress of photopolymerization processes or thickness of polymer coatings by the Fluorescence Probe Technique (FPT) was studied. Three groups of samarium(III) complexes were evaluated in cationic photopolymerization of triethylene glycol divinyl ether monomer (TEGDVE) and free-radical photopolymerization of trimethylolpropane triacrylate (TMPTA). The complexeswere the derivatives of tris(4,4,4-trifluoro-1-(2-thienyl)-1,3-butanedionate) samarium(III), tris(4,4,4-trifluoro-1-phenyl-1,3-butanedionate)samarium(III) and tris(4,4,4-trifluoro-1-(2naphthyl)-1,3-butanedionate)samarium(III), which were further coordinated with auxiliary ligands, such as 1,10-phenanthroline, triphenylphosphine oxide, tributylphosphine oxide and trioctylphosphine oxide. It has been found that most of the complexes studied are sensitive enough to be used as luminescent probes for monitoring progress of cationic photopolymerization of vinyl ether monomers over entire range of monomer conversions. In the case of free-radical polymerization processes, the samarium(III) complexes are not sensitive enough to changes of microviscosity and/or micropolarity of the medium, so they cannot be used to monitor progress of the polymerization. However, high stability of luminescence intensity of some of these complexes under freeradical polymerization conditions makes them good candidates for application as thickness sensors for polymer coatings prepared by free-radical photopolymerization. A quantitative relationship between a coating thickness and the luminescence intensity of the samarium(III) probes has been derived and verified experimentallywithin a broad range of the thicknesses.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: In this paper an algorithm for accurate delineation of object boundaries is proposed. The method employs a superpixel algorithm to obtain an oversegmentation of the input image, used as a constraint in the task. A shape model is built by applying Principal Geodesic Analysis on angular representation of automatically placed uniformly distant landmark points. The shape model is used to detect the boundaries of an object on a given image by iterative elongation of a partial boundary along borders of superpixels. Contrary to many state-of-the-art methods, the proposed approach does not need an initial boundary. The algorithm was tested on two natural and two synthetic sets of images. Mean Dice coefficients between 0.91 and 0.97 were obtained. In almost all cases the object was found. In areas of relatively high gradient magnitude the borders are delineated very accurately, though further research is needed to improve the accuracy in areas of low gradient magnitude and automatically select the parameters of the proposed error function.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Super-time-stepping denotes a class of special strategies of choosing nonuniform time steps in finite-difference solutions of partial differential equations by conditionally stable explicit techniques, that allow one to effectively overcome limits of numerical stability. This is achieved by demanding the stability only at ends of certain sequences of time steps, called supersteps. The utility of one variant of the super-time-stepping is examined, for digital simulations of electroanalytical experiments described by reaction-diffusion partial differential equations in one-dimensional space geometry. The tests focus on example models of chronoamperometry and cyclic voltammetry. Reductions of computational times, and improvements of the efficiency of such simulations are observed. Implementation of the super-time-stepping requires only minor changes in computer programs for conventional explicit simulation methods. Super-time-stepping can be combined both with sequential and parallel computations, but it should be of particular interest in connection with the efforts towards parallelisation of electroanalytical simulations.]]>

rodzaj: materiały konferencyjne w książce
Abstrakt: In the 1950s, Alison and Peter Smithson, somewhat unfortunately used the term brutalism to name an emerging trend. In English, the element of brutality of this term turned out to be very strong, creating negative thinking about architecture made of raw concrete. However brutalism is not only the rawness of the material, it is also an expressive architectural form, and this rawness emphasizes this expressiveness. Brutalist architecture is often sculptural, but above all it is massive, dominating over its surroundings, consciously negating context, it can even be said that it is totalitarian, which in some sense justifies the popularity of this style in former communist countries, including Poland. In this fact we can see the reasons for the contemporary aversion to the use of the word "brutalism". The ideological layer is interesting as well. The Smithsons wrote that" "Brutalism tries to face up to a mass-production society, and drag a rough poetry out of the confused and powerful forces which are at work [1]." Brutalism is a favorite movement of artists and this is also the most hated one by so-called ordinary people. In the royal city of Cracow, a city known for its conservative approach to architecture, there were several interesting projects representing this movement during the communist era. They include the "Bunker of Art" or the Forum Hotel. Although it is believed that the time of brutalism has passed, works in its spirit are still being created in Cracow. Perhaps the semantic clumsiness of the Smithsons is the reason that nobody calls them brutalist today.]]>
<![CDATA[The impact of deepening the stilling basin on the characteristics of hydraulic jump]]> Tue, 17 Apr 2018 10:51:41 +0200 Siuta, Tomasz
rodzaj: artykuł w czasopiśmie
Abstrakt: In this article, the results of computational fluid dynamic (CFD) modelling of the hydraulic jump conditions occurring in the experimental prismatic rectangular stilling basin with sudden crosswise expansion are presented. The FLOW 3D software program was used to numerically solve Reynolds Navier-Stokes (RANS) equations with the application of the k-ε turbulence model. The influence of the depth magnitude of the stilling basin and the ending sill installation on the hydraulic jump turbulent characteristics and submergence condition changes was investigated. Based on the results of the numerical modelling, it was found that various spatial flow processes contribute to the submergence condition of the hydraulic jump. These processes include: crosswise flow expansion within the stilling basin; local tail water surface level increase and total head loss due to vertical flow contraction; installation of the additional terminal sill. This contribution to the submergence condition allows a reduction in the required depth of the stilling basin, calculated on the basis of a one-dimensional simplified approach without consideration to the spatial characteristic of the hydraulic jump.]]>
<![CDATA[Plants as natural anti-dust filters – preliminary research]]> Tue, 17 Apr 2018 10:47:13 +0200 Mazur, Justyna
rodzaj: artykuł w czasopiśmie
Abstrakt: In urban areas, particulate matter (PM) are the leading cause of air pollution. They can adversely affect human health. One of the solutions to reduce pollution and improve air quality is the use of plants as natural, biological filters which trap the particles on the leaves. Studies on the assimilation capacity of species (Hedera helix, Parthenocissus quinquefolia, Fagus sylvatica) were analyzed. In addition, based on two examples of structures in Krakow, the storage capacity of vines such as Hedera helix and Parthenocissus quinquefolia and Fagus sylvatica tree, for fraction of PM (0.2–2.5 μm; 2.5–10 μm; 10–100 μm) was estimated. Analyses have shown the particular efficacy of creeping vines in PM capture.]]>

The project contains an assumption of a steady concentration of the distillate. Thee range of change in the reflux from 1.7 to 13 required to obtain that concentration was calculated. With 50 litres of feed containing 9 mol % ethanol, about 10 litres of distillate was obtained, which has 70 mol % ethanol. Ceramic Raschig rings with a diameter of 15 mm, which, in a column, occupy a height of 0.5 m, were used. The height of the entire column was 0.67 m.]]>
<![CDATA[Characteristics of producing ethyl alcohol]]> Tue, 17 Apr 2018 09:52:53 +0200 Jamróz, Justyna; Jankowski, Dawid
rodzaj: artykuł w czasopiśmie
Abstrakt: The paper presents the introduction to problems related to the distilling industry in Poland and its current situation. The theoretical issues related to the production of ethyl alcohol are discussed. The raw materials used and their impact on production efficiency, process steps and their conditions and quality requirements for alcoholic beverages based on ethanol are characterised. The main causes of the problem of distillery in Poland are seen in the import of cheap rectified and dehydrated spirits from other EU countries, which results in a fall in market prices that do not provide for reimbursement of production costs and increase of excise duty in 2014, which significantly contributed to the closure of the distillery. At present, there are around 100 of them in the country, most of which are made of distillates for bio ethanol production.]]>

rodzaj: rozprawa doktorska
Abstrakt: The research contains an analysis of stiffness of Polymer Flexible Joint (PFJ). The basic aim of the research was to obtain the values of stiffness of flexible joints between precast concrete elements of rectangular cross-section. All the experiments in this research concern only primary load curve and speed of deformation of 100%/min. 239 laboratory experiments were held, concerning specimens under shear, bending, tension and compression load. All the experiments were modelled in Abaqus 6.12 FEM software. A comparison analysis of experimental and numerical results was performed. Due to noticed differences, an identification of the polymer hyperelastic material was done. The accuracy of obtained model was presented basing on plenty of examples. A large-size experiment of a real-scale specimen of 3.2 m length was also held. Basing on obtained results, the accuracy of the numerical model and the magnitude of possible strain in real construction is shown. Several analyzes were performed using the obtained experimental results, e.g. scale effect and stress distribution, as well as analysis of usefulness of PFJ in the real engineering constructions. For all the analyzes, conclusions were drawn and directions of further research connected to PFJ commercialization were identified. ]]>

Heidenhain’s scanning probe head was installed. Programs and software allowing the use of PC-DMIS measurement software were written.]]>
<![CDATA[3D vs. 2D modeling of concrete gravity dam subjected to mining tremor]]> Thu, 12 Apr 2018 09:07:36 +0200 Dulinska, Joanna
rodzaj: materiały konferencyjne w książce
Abstrakt: The paper indicates the role of 3D modeling of concrete gravity dams in evaluation of dynamic response of dams to mining tremors which occur in mining activity regions. 2D and 3D models of a concrete gravity dam were prepared in order to compare two-and three-dimensional analysis of the dynamic response of dam to mining shock. Firstly, values of natural frequencies obtained for 2D and 3D models occurred to be very similar, but only the 3D model allowed to predict the dam behaviour under longitudinal kinematic excitation. Secondly, the comparison of the maximal principal stresses obtained for 2D and 3D models indicates that the simplified 2D analysis underestimates the values of dynamic response on about 20 %. Three-dimensional dynamic analysis allows to assess internal stresses resulting from mining shock more precisely, since the amplitudes of ground vibrations during mining tremors are comparable in three directions. ]]>

rodzaj: rozdział/fragment książki
Abstrakt: An analysis of the problems of the reliability properties impact on the value of a company’s fixed capital is presented. The interdependence between reliability, costs and economic effects and the value of technical components of the fixed capital is obvious but difficult to identify, which is the basis for the problem synthesis. Good knowledge of them offers an opportunity to compare the effectiveness of fixed capital components of various reliabilities, and shape their values as the company’s capital. The comparability in the aforementioned scope is the starting point for the development of reliability optimisation calculation principles to ensure the maximum efficiency of business enterprises. The effect of the research behind the paper is the indication of the functional dependence between the fixed capital components value and reliability indicators dynamics. On the basis of this dependence the essential economic values that affect the correct functioning and shaping capital management of a business can be determined.]]>
