“Playing games with architecture” – Per Kirkeby’s fake buildings
Get PDFThe text describes play with architecture in the work of the Danish artist Per Kirkeby. His spatial installations, bordering between sculpture and architecture, show the interaction between the obvious and elusive, real and fictional, abstract and archetype
The development of the real life model of the five node power system
Get PDFThis paper presents the process of the development of the real life laboratory model of the five node power system of closed loop structure. The model was built using ‘power’ scaling and taking into consideration the parameters of the 400 kV lines built in the Polish National Power system. After the three-year development of the model, the parameters of the elements of this model were gained or obtained using classic identification procedures. During this part of the research, some differences between the parameter values given by the manufacturers and those obtained through identification procedures were reported and analyzed. The Matlab/Simulink model of the laboratory setup was then built to emulate the system behavior during dynamic states. The comparison of the currents, voltages and generator speeds proved to be simple tasks since the shape of the short-circuit current waveforms, for example, depends not only on parameter values but also on the time of the fault occurrence with respect to system voltages. Thus, the time responses of the laboratory and Simulink models were compared to evaluate time constants of the post fault processes
From museum to centre of social life – the modern concept of botanical gardens
Get PDFBotanical gardens have functioned as museum facilities for generations, but this model is slowly being abandoned. Increasingly, they are becoming vibrant social centres (especially in the United States and Western European countries). Does the increase in the social role of botanical gardens present an opportunity or a threat to their development? Examples of gardens such as the Eden Project or San Francisco Botanical Garden show that the new concept of botanical gardens can bring many social and even economic benefits
Improvisation. Sketch. Synthesis. Short forms in architectural education
Get PDFThe game is a particular aspect of human activity, organized and limited by rules, with a result, though not a material outcome. In the process of creating architecture we undertake activities associated with the notions of fun and game. This also, or primarily, applies to architectural education, which, in short, free forms seeks experience and inspiration for further, serious design solutions
Synchronous motor prototype with an external rotor using permanent magnets
Get PDFThis paper presents the design, simulation and measurement of a synchronous motor prototype with an external rotor using permanent magnets. The motor was optimized for high-torque, in-wheel operation. Based on geometric dimensions, a 3D solid model was created. The electromagnetic design was calculated in ANSYS/RMxprt. A cross-section with graphical presentation of magnetic induction in particular parts of the electromagnetic circuits and the simulated and measured characteristics of the motor are shown
The game in space – the phenomenon of an urban game
Get PDFIn the paper, the phenomenon of the urban game is presented in the context of its applicability to architectural education. In the perception of the average inhabitant, the town is only a background for daily activities, and architecture is designed to secure his basic needs. The recent crisis in spatial interactions, analogous to the crisis in social interactions, can be overcome through skilful use of non-standard methods of activating inhabitants – fun and games
Numerical modelling of the optical demultiplexer photonic structures
Get PDFPhotonic structures and their application are one of the most intensively studied areas of modern optics. They are used in devices such as blue lasers, optical fibres or optical add-drop multiplexers. The paper describes the possibility of designing the photonic structure of the optical demultiplexer using the application written by the authors
Green cities
Get PDFThe changes in the system of urbanization, initiated by research and the resulting designs at the turn of the 19th and 20th centuries, consisted ‘consisted’ implies there were no either kinds of changes, if you don’t mean that, use ‘included’ and take out ‘of’ of increasing the share not sure what you mean by share in this context, might ‘proportion’ be better? of green areas in urban spaces. Actions aimed at improving the human urbanized living environment, induced by the U’Thant’s report and subsequent international documents, now seem to have been a permanent development trend. Simultaneously, other actions may be observed, relating to the introduction of smart technology solutions into the urban area aimed primarily at focusing on the maximized use of urban space and additionally at sustainable development. Sometimes, the need for contact with the natural environment is the reason for seeking the direct experience of large areas of attractive natural environment. Hence, more and more often, the latest urban creations boast high quality spaces featuring perfectly organized and developed green areas
Philosophy of exact sciences (logic and mathematics) in Poland in 1918–1939
Get PDFThis paper describes the philosophy of logic and mathematics in Poland in the years 1918‒1939. The special attention is attributed to the views developed in the Polish Mathematical School and the Warsaw School of Logic. The paper indicates various differences between mathematical circles in Warszawa, Lvov and Kraków
Urban recycling – design strategies fulfilling the needs of contemporary cities and their societies
Get PDFThe article presents the problems connected with the transformation of urban structures, which use the existing resources. A more in-depth analysis was conducted in terms of chosen methods of urban recycling that help to both preserve the deteriorating buildings and places in cities, and to use them temporarily while waiting for the final modernization
