Both collective publications (Prefab houses 1: Fifty prefab housing schemes in the Czech Lands. A critical catalogue of the “Prefab house story” series of exhibitions and Prefab houses 2: History of housing schemes in the Czech Lands 1945–1989. A critical catalogue of the “Residence – prefab housing scheme: Planning, realization, housing 1945–1989” exhibition) are products of a broadly conceived interdisciplinary research project the deliverables of which included, inter alia, exhibitions in Prague and all regional capitals of the Czech Republic and which were awarded the prestigious Magnesia Litera prize in 2018 as an extraordinary feat in the fi eld of professional and educational literature. In the reviewer’s opinion, they bring the fi rstever systematic attempt to periodize the prefab-based building projects in the Czech part of the former Czechoslovakia between the mid-1940s and the end of the 1980s, at the same time providing a multifaceted characterization based on a representative sample of fifty prefab housing schemes in Bohemia and Moravia. and Each of them was subjected to a thorough artistic-historical analysis outlining the development of the housing scheme’s concept, providing brief information about its authors, describes its urbanistic concept, prefab technology used, and artefacts and decorations. Added to the above is a set of interdepartmental studies analyzing different aspects of the historical development of prefab housing schemes. The compact collective of authoresses and authors has succeeded in presenting the prefab housing schemes, no matter how similar they may seem, as a varied and dynamically developing phenomenon, which fact is underlined by excellent work with archival photographs and the generally outstanding graphic layout of the publications. The only critical comment the reviewer has is that the authors were so absorbed by the architectural aspect of the matter that they tended to overlook substantial changes of the socialist urbanism in Czechoslovakia.
This text is directed to the summarized description and physical interpretation of the basic structure of a radar from the standpoint of the theory of signal processing. after introductional and functional classification of radars, this text contains the treatise of a representative radar block model and of the characteristic signal properties of partial radar subsystems, containing the radar transmitter with signal waveform generator, radar antenna and radar receiver with the signal and data processor and display. For better orientation in the problems, the english synonyma are added to some established Czech expressions., Tento text je zaměřen k shrnujícímu popisu a fyzikální interpretaci základní struktury radaru z hlediska teorie zpracování signálů. Po vymezení a funkční klasifikaci radarů obsahuje pojednání o reprezentačním blokovém modelu radaru a o charakteristických signálových vlastnostech jeho dílčích subsystémů, k nimž hlavně patří radarový vysílač s tvarovacím signálovým generátorem, radarová anténa a radarový přijímač se signálovým a datovým procesorem a obrazovkou., and Pokračování článku z minulého čísla.
