Drivers clothing thermal resistance database for iHVAC system
Hrubanová, Kristýna ; Pokorný, Jan (referee) ; Fišer, Jan (advisor)
This diploma thesis is focused on measurement of thermal properties of clothes by thermal manikin and on application of results for prediction of thermal comfort in system iHVAC. First part of thesis is dedicated to research with relation to this topic and to definitions of main computational equations necessary for experimental measurement. The choise of method for measurement based on available standards is an important part of this thesis. The main focus of thesis lies on measuring 5 combinations of clothes at different calibration temperatures and same temperature of manikin surface. Then data are examined and also the analysis of uncertaities and repeatability is maked. According to assupmtion , the independence of value of heat transfer coefficient to ambient temperature is comfirmed and calculated heat resistance of every single clothes is compared to existing wardrobe for system iHVAC. The outcome of this thesis is specificied and completed virtual wardrobe which serves to prediction of thermal comfort in car.

Development of the anchor expansion silicate based material with thermal resistance
Müller, Jiří ; Bydžovský, Jiří (referee) ; Drochytka, Rostislav (advisor)
The research conducted focused on studying the development of expansive, silicate based- anchor materials that were resistant to high temperatures. The results showed that shrinking is a critical property as volume can change (mainly cause shrinkage) the anchoring materials. This can ultimatly lead to a collapse of a loaded connection. The aim of the study was to summarizing products on the market, to develop the development of anchor matters alone and methodology for testing. Selected were directly related to expansion and thermal resistence.

Manufacturing, use and properties of nickel alloys
Kejha, Richard ; Blažík, Petr (referee) ; Záděra, Antonín (advisor)
This thesis presents a literary recherche of matters concerning on industrial use of nickel aluminates, especially on refractory and incandescent alloys. In this dissertation are witten basic market brands of constructional, refractory and incandescent alloys, and then their selected representatives. There are listed the basic properties of given materials and their approximate comparison. The basic constructional materials are monel alloys based on Ni-Cu, which achieves very good mechanicl properties and excellent corrosion resistence. Refractory and incandescent materials are mostly based on Ni-Cr or Ni-Cr-Fe. Their mechanical features are very different in normal conditions and even in high operating temperatures because there are used different kinds of addition elements and their concentration. These alloys are usually additioned by elements like W, Cu, V, Al, Nb, Ti, Ta, Mo, Co, Zr, B.
