Properties of liquids based on organic esters
Toulová, Jana ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
This master's thesis deals with the electrical insulation fluids used in electronics industry. The analysis of the current state of research and innovations in modern, biodegradable fluids in terms of their use as diagnostics. It is described by the physical nature of polarization and conductivity mechanisms, which are applied in liquids. It was compiled automated workstation for monitoring components of the complex permittivity over a wide temperature range. In the experimental part we analyzed the behavior of liquids selected alternative based on natural esters when exposed to an alternating electric field at various temperatures. Evaluated results are compared with values for conventional mineral oil.

Electrical properties of modified oligobutadienes
Toulová, Jana ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
Bachelor thesis deals with the behavior of dielectric materials in an alternating electric field. To identify the properties of dielectric materials in the frequency domain method was employed dielectric relaxation spectroscopy. On several samples of modified oligobutadiénů were measured frequency dependent components of the complex permittivity in the temperature range of negative temperatures, the ambient temperature.

Economic Relations between Czech Republic and Canada
Toulová, Jana ; Jiránková, Martina (advisor) ; Kačírková, Eliška (referee)
The topic of my bachelor thesis is Economic Relations between Czech Republic and Canada. I set goal of my thesis to be to evaluate economic relations between Czech Republic and Canada and based on the evaluation characterize current their economic relation and assess future potential. The thesis is divided into three chapters. First chapter describes economy and international trade of both countries separately, and focuses on their basic characteristics. Second chapter devotes to mutual relations and mutual trade of both countries. The historical and current situation of mutual relations is considered when assessing this matter and regarding mutual trade balance of trade, commodity and territorial structure is taken into account. Third chapter looks into the planned Comprehensive Trade and Economic Agreement between EU and Canada and expected impact on relations between Czech Republic and Canada.
