Ranque-Hilsh vortex tube
Obrlík, Jan ; Brázdil, Marian (referee) ; Šnajdárek, Ladislav (advisor)
Ranque-Hilsch vortex tube is thermally-fluid device in which there is a conversion of the pressure energy of the incoming fluid stream to heat energy of two exiting streams without any mechanical parts. The first part of this paper deal with the basic distribution, applications and principle of the vortex tube, which is not fully understood. In the second part there has been carried out a search about performed experimental measurements. Based on this research is designed optimized experiment. The last part of work is the evaluation of the measurement, which was carried out on an industrial vortex tube.

Peřina, Martin ; Feiler, Zdeněk (referee) ; Koláčný, Josef (advisor)
This thesis is focused on selected kinds of piezoengines and their ability to control and follows the separate semester project. It mainly deals with technnology called Piezo LEGS and Piezowaves. Attention is paid to their structure, principles, parameters, characteristics, but also to field of their application. Next section is laboratory measurement of those species of piezoengines (demo-kits). At the end thesis contains three laboratory task, each type of engine is dedicated toone task. The contents of the work is focused on innovation activities in the learning process.

Principles of private law
Andraško, Richard ; Dvořák, Jan (advisor) ; Elischer, David (referee)
Principles of private law The reason of choosing "Principles of private law" for my thesis is that private law is built on untouchable values. For example, basic values like freedom and equality, which are represented by these principles. Many of them are indispensable in the relation of functionality of the whole system of law. Most of them have Roman law origin. The purpose of my thesis is to describe and summarize the main principles of private law that mostly appear in Czech law, especially in civil law. It also examines the influence of re-codification of private law on these principles and relationship between them. The thesis is composed of two parts. Part one, named general part, is introductory and defines different meanings of principles of law in Czech jurisprudence. It deals with historical perspective (Roman law connections to principles of law) and philosophical context (represented by concepts of legal positivism, theory of natural rights and sociological concept of law) of principles of law. It also describes the theory of principles of law by Ronald Dworkin. Part two, named specific part, focuses on principles of private law and contains the overview of them. It deals with legal regulations of these principles and their definitions according to judicial decisions. It also examines...

Principles of taxes and fees
Kouba, Stanislav ; Vybíral, Roman (referee)
Added value of this thesis is to order principles of taxes and fees into a system, which allows its easier application in context of tax law and law of fees. This system then uncurtain joint relations among these principles and enable its further analysis. The result is a system (tree) of principles within which principles are divided according to different criteria. They can be sorted into three groups, namely the principle of regulatory intent (there are mostly the principles of the other disciplines; these principles determine intent, reason and purpose of the regulation), the principles of regulatory instrument (it is created by the principle of legal state; these principles represents legal dogmatic) and the principles of efficient regulation (here everything follows from the principle of economy). Thesis target on material side of problem which it differs from the other thesis on this topic. An essential partial step toward revealing the system of principles is also a definition of tax and definition of fee and also analysis what is the principle.
