The Life and the Work of the Prague Carpenter Michael Ranek
Bláha, Jiří
The designs of the low-cost roof trusses created at the end of 1820s by Prague carpenter of Hungarian origin Michael Ranek (1770-1842) form a sort of link between traditional trusses with collars and modern purlin constructions. The swift adoption of Ranek’s truss among carpenters was helped by the relationship of trusses to traditional collar systems, easier handling of beams with smaller profiles and last but, not least, its simplicity during fabrication and erection. During the course of the second half of the 19th century Ranek’s trusses, together with traditional trusses with collar beams, were forced out by new, progressive constructions, especially by the generally widespread purlin trusses.

Timber Roofs in the Southern Part of Bohemian-Moravian Uplands
Bláha, Jiří ; Kyncl, T.
The vast majority of historic roofs in the region belong to the common rafter and collar typological group. The large diversity and variability of technical solutions, especially noticeable in the lengthwise frame construction allows us to trace the evolution of traditional carpentry as well as to map its local differences. The Bohemian-Moravian Uplands region is one of the relatively homogenous areas, where the timber transport distance from the place of felling the trees to the site was very short. There are no large rivers, and the altitude is 500-840 meters (about 1500-2500 ft.)above sea level.

Advanced detection methods used for on-site inspections of historic timber structures
Bláha, Jiří ; Drdácký, Miloš ; Kloiber, Michal
Research and evaluation of timber structures used within historic buildings should have consideration for an authentic substance bearing the most of specific heritage values. Modern technologies have brought new tools for a detection of the subsurface biogradation. Among the non-invasive techniques the ultrasonic testing, portable X-ray scanning and thermo-vision belong to most promising ones. There are also sophisticated semidestructive methods like microdrilling or video scope available.

Interkulturní management
Jetmarová, Denisa Bc. ; Kovář, František (advisor) ; Bláha, Jiří (referee)
Práce se zabývá shrnutím základních teoretických poznatků o interkulturním managementu dle Hostedea, Schwarze, Hampden-Turnera, Trompenaarse, Bourdieu a Scheina; dále jsou řešeny rozdíly české, slovenské, polské, ukrajinské a mongolské kultury zjištěné na základě výzkumu VSM 08 provedeného ve společnosti Isolit-Bravo, spol. s r.o. a jejich uplatnění v managementu firmy.
