The mathematical model of the operating mechanism for turbochargers
Jakubec, Ján ; Porteš, Petr (referee) ; Zháňal, Lubor (advisor)
The Diploma Thesis is focused to create the mathematical model of operating kinematic model for turbocharger DAVNT (Double Axle Variable Nozzle Turbine) for setting the position of vanes. The work contains a brief overview of supercharge and types of turbochargers. The main part contains a mathematical model which examines the behavior of the mechanism with considering of wear among the parts. It also includes assessment of changing in various parts of the nodes caused by mechanism wear and their influence on the mechanism due to important parameters which characterizes the mechanism. The evaluation is completed by optimizing the parameters. The final section contains the static calculation of internal forces and assessment of actuator position relative to mechanism load.

Rationalization of a manufacturing system at Prodia company
Jakubec, Jan ; Navrátil, Petr (referee) ; Kubík, Roman (advisor)
The work deals with the optimization of the production system in the engineering company Prodia s.r.o. There is a review of technological design in the introduction, the methods of analysis, design methods and capacity calculations are introduced. Subsequently, using these methods, the current state of material flows are analysed, the critical points in the production defined and design of new solution options to eliminate the main weaknesses identified during the analysis. Finally, an evaluation of the best variant and its economic profitability is introduced.

Pressure measurement
Jakubec, Jan ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
The project elaborated in a scope of engineer studies in branch 2301R016 submits summary of various methods of pressure measurement. Literary study draws up possibilities and variants of pin-pointing the absolute, relative and barometric pressure, suction, excess pressure and vacuum with analysis of its significance for engineering procedures. Main area is pressure of fluid, piston and bell-shaped gauges, deformation and electrical with examples of their practical use in engineering.

Legal regulation of employment and welfare during unemployment
Jakubec, Jan ; Vysokajová, Margerita (advisor) ; Štangová, Věra (referee)
Legal regulation of employment and security against unemployment At the present time of economical recession many countries battle against high unemployment, which can contribute to many economical and social problems. The purpose of my thesis is to describe legal regulation of employment and security against unemployment in the Czech Republic. I focused on main parts of legal regulation and also thought over some institutes. When I came to the conclusion, that the legal regulation has some drawbacks, I suggested that an amendment should be passed. The thesis is composed of eight chapters. Chapter one defines unemployment and its kinds and elucidates, what full employment means, because it is the aim of legal regulation of employment in many countries. At the end of this chapter I sumarize developement of unemployment in Czech Republic from 1990 to present. Chapter two deals with right to work. I enumerate most important international documents, where right to work is regulated. Full employment was also soon mentioned as the basic aim of countries. Similar developement in Community law is described in part four. At the end of chapter is comparison between the right to work under Charter of Fundamental Rights and Freedoms and right to work under Employment Act. Chapter three deals with employment policy in...
