Mounting of leads by brazing on alumina substrate
Neradil, Petr ; Adámek, Martin (referee) ; Otáhal, Alexandr (advisor)
Bachelor´s thesis deals with the issue of implementation hybrid integrated circuit terminals for performance applications. It also states the advantages of each type of terminals and their technology. It discusses the materials used for brazing and describes problems of brazed in the electrical industry. The thesis also presents techniques for brazin of leads by brazers on the ceramic substrate. The conclusion contains the results of thermal and mechanical tests of the resulting connection.

Rheological properties analysis of heat transfer fluids
Neradil, Petr ; Hylský, Josef (referee) ; Frk, Martin (advisor)
This master thesis deals with the issue of heat transfer fluids for solar thermal system. It discusses the different types of solar systems and their use. It also describes the different types of heat-transfer fluids for solar thermal systems and analyzes the basic chemical composition of commercially available heat-transfer fluids. There are described the properties of these fluids and methods for measuring certain properties. The practical part deals with measuring the temperature dependence of density and dynamic viscosity of alternative and commercially available heat-transfer fluids, determining the freezing point and compares the results.
