The present article undertakes a trial of assessing the losses suffered by a fishery establishment in connection with the fact that it realizes its production on a terrain where water birds are present, these birds being protected by the law. Research has been carried on by three methods: 1) in a systemic approach with calculating the profitableness of the property being at the disposal of the economic...
The aim of the presented program for computer-based assisting the preliminary (preparatory) phase of the architectural process is to intensify and facilitate architectural design activity. This program is a specialized tool, which - in the preliminary phase of the architectural process -facilitates methodically creating variants of forms of the architectural project. It is the first computer-based...
When badly informed, even a genius draws false conclusions and then makes a wrong decision. The very simple phrase of the motto above includes an immensity of problems and questions, to which many science domains are trying to answer - from systems theory, sociology, praxiology, cybernetics, through methodologies of particular domains, to design and exploitation in technology. All these areas, and...
In the contribution, new ways of facilitating architectural design and enlarging its creative and technical possibilities are discussed, with applying elements of the existing knowledge of design methodology and systems knowledge. A description of selected methodological design operations in architectural design is presented, as well as of the architectural process from the point of view of design...
In the contribution, the process-based orientation of an enterprise has been defined and four main dimensions of the process-based orientation have been proposed and characterized: the processes, the education of the workers, the culture of the organization and the customer. The starting point of the considerations was a review of definitions of the concept of process-based orientation.
The topics presented in this article are based upon an exact analysis of the concept of social exclusion as well as of the struggle against such exclusion. In the analysis of the problem the systems-based approach has been applied. This approach has permitted to see the phenomenon in a quite other light. During the realization of the work attention was paid to a lack of harmony in realizing activity...
When taking into consideration the rich resources of hard and brown coal in Poland and the necessity of exploring deeper and deeper deposits, the functioning of machinery working in pit shafts is of great importance, also machinery for removing dangerous and harmful contaminations from the excavation area. The ways of installation of a fan are discussed, as well as characteristics of axial and centrifugal...
Writer Warren Ellis coined the term burst culture to reflect a culture receiving its entertainment and information in bursts; gaining as much information and experiencing as many narratives within as short a period of time as possible. In order to achieve this, burst culture is forced to make severe choices which jeopardize established business models (when the audience chooses to bypass commercial...
On the basis of drawings left by Le Corbusier, concerning his architectural process of designing the Carpenter Center, a methodological and systems-oriented interpretation was performed of elements of the creative process. The being analyzed elements of the preliminary (preparatory) phase of the architectural designing process of the object of the Carpenter Center of Le Corbusier constitute, indeed,...
The paper presents quantitative characteristics of a bottleneck in an inventory system composed of the following subsystems: production, transport, storage, and receiver. The characteristics are derived by solving an appropriate system of differential equations. The author points out certain possibilities of improving the efficiency of the functioning of the investigated system. Methodological considerations...
The paper proposes concepts for measuring knowledge and artificial intelligence based on the notion of natural intelligence as defined and developed throughout ages. It discusses also prerequisites for the origin of artificial intelligence and virtual knowledge and points out difficulties encountered when attempts to introduce scales and measures in this area are undertaken. In view of a tremendous...
The paper shows a study of modernization of municipal heating plant to heat and power generating plant combined heat and power) integrated with biomass gasification. Two variants of modernization are considered in the paper. The first case bases on the gas turbine integrated with thermal biomass gasification unit (gasifier) and the heat exchanger located behind the gas turbine. In the second case...
The results of testing the effect of concentration of water mixture of slag and ash on the propagation rate of sediment have been presented in this paper. Experiments have been conducted, which consisted in pouring simples with different mass concentrations onto a flat surface, and the time of propagation of the samples in the trough has been tested. The effect of concentration of the mixture on the...
In the article some issues have been presented regarding a tube probe for collecting deposits from the vicinity of the boiler superheater, fuelled by solid fuels. The probe is cooled by the inside flow of compressed air which later goes into combustion chamber. An algorithm of heat-related calculations has been proposed taking into account the exchange of heat between the flue gas and the external...
The announcement of the European Commission concerning the European strategy in frame of power industry was published in 2007[1]. The document contains the main priorities of energetic politics of EU even to 2050. They are: - joint energy market - counteraction of the climate warming - European strategy for the security of energy supply in the case of the sharp energetic crisis. All priorities are...
A loss-of-coolant accident (LOCA) is one of the most serious accident which may happen in the nuclear factor cooled and moderated by water under a high pressure. A threat of the core uncover during such accident causes that LOCA became a design basis accident (DBA) and have to be simulated to prove that engineered safety systems are able to manage the potential consequences of such accident. It is...
In this paper the authors has presented methodology of determination of control stage wheel thrust force basing on 0D and 3D models. One has determined portion of particular thrust force components acting on shroud, airfoil and rotor disc. The authors has also presented radial distribution of static pressure acting on the rotor disc (with usage of 3D tools). One must emphasize that 0D model (checked...
In this paper, simplyfied analysis of different conditions of wind power expansion in Poland is shown. This analysis is made on basis simplyfied computational example of 18 MW wind farm in Poland from the point of view of different group of parameters. Four groups of conditions: wind, geographical, technical and economical are taken into consideration. Introduction is contained short analysis of wind...
The impellers of multistage pumps has lower suction performance. To improve pumps suction performance was designed helical inducer. The flow field behind inducer was changed and it was different from normal inlet flow to impeller. This paper described a numerical investigations the influence of changeable flow field behind inducer on suction performance centrifugal impeller. In the results changeable...
Adapting power stations to combined heat and power generation will enablea substantial reduction of primary fuels consumption and emission of their noxious combustion products to the natural environment. Complex thermodynamic and economic analysis of adaptation methods is necessary. The paper presents thermodynamic analysis a 380 MW power block adapted to combined heat and power generation.
