Lubricant film formation in compliant contact
Jaroš, Tomáš ; Čermák, Jan (referee) ; Nečas, David (advisor)
This diploma thesis deals with the study of film formation in compliant contact. Primary attention is dedicated to the influence of the entrainment speed and slide-to-roll ratio (SRR) on the central film thickness. Based on a research study of the available experimental methods, the fluorescence microscopy was used to achieve the aim of the work. Experiments were realized in ball-on-disk configuration. Firstly, a validation of the method was performed where the solid contact of the ceramic ball and the glass disk was analyzed. Since the measured values were in a good agreement with the theoretical prediction, a ball of NBR rubber material, which is commonly used for production of lip seals and o-rings, was subsequently used. The experimental measurements were performed under pure rolling and rolling/sliding conditions when the entrainment speeds varied in the range from 10 to 400 mm / s. A constant load of 0.2 N was applied. The measured data were then compared to the theoretical predictions for compliant contacts. The results showed that the thickness of the lubricating film gradually increases with increasing entrainment speed, which corresponds to theoretical assumption. Against expectations, evident influence of SRR on the film formation has been observed. In the last part of the thesis the measured data are confronted with previously published studies. Finally, some limitations of this study are discussed and recommendations for further improvement of the used experimental method are suggested.

Control of power LEDs
Jaroš, Tomáš ; Florián, Tomáš (referee) ; Kopečný, Lukáš (advisor)
The work deals with controlof high power LED modules. The introductory part shows theory of LED diodes. Next part is dealing with source supplies, their kinds and attributes. Then we deal with possibilities of current limiting. Next chapter shows switching power supplies. Aim of this work is to design wiring for power control LEDs and the resulting implementation by designing a suitable controller.

Design of hillside elevator
Jaroš, Tomáš ; Smejkal, David (referee) ; Dvořáček, Jiří (advisor)
This Bachelor´s Thesis presents a structural proposal of a hillside elevator to a house on the slope used to carry goods and people. The elevator is designed in a total length of 40 meters with a capacity of 400 kilograms and slope of 25 degrees. The main focus aims at the drive of the machine and its safety. The elevator fulfills prescribed safety terms according to the 127/2004 directive. A 3D model of the elevator, a design drawing and drawings of its individual components are included.

Univerzita Karlova Filozofická fakulta Ústav světových dějin Historické vědy - Obecné dějiny Tomáš Jaroš Konflikt na Blízkém východě a mezinárodně politická role Německa v mírovém procesu na počátku třetího tisíciletí The conflict in the Middle east and internationally, the political role of Germany in the peace process at the beginning of the third millennium Abstrakt dizertační práce 2017 Prof. PhDr. Václav Horčička, Ph.D. Title: The conflict in the Middle east and internationally, the political role of Germany in the peace process at the beginning of the third millennium Abstract: The theme of the presented work is the conflict between the two parties for the entry into of the problem and his suggestion how to solve the resulting dispute and the subsequent review of the German policy in the Middle east from a German perspective to the war outbreak. The first part of the work focuses on the content and the nature of the conflict between Israel and Palestine. The second part will be an analysis of the actual German middle east policy, as shaped, change and implement the federal government since the early fifties.The second half of the second section will provide interpretation of the German middle east policy at the turn of the second and third millennium. This section will outline and explain the three...
