Redesign of Vibration Power Generator with Respect to Overall Volume and Weight
Vaněček, Michal ; Dušek, Daniel (referee) ; Hadaš, Zdeněk (advisor)
This work deals with improvement construction already of the vibration power generator design. The improvement his feature and search ideal construction with reference to material, proportions and power. Gain here mechanical properties, to come to what best tune up and development of new construction for improved check out characteristics as is achievement. Tuning up of correct parameters proceed by the simulation and modelling in ANSYS and MATLAB environment.

Infuence of eardrum position on sound transmission
Krbálek, Jaroslav ; Dušek, Daniel (referee) ; Pellant, Karel (advisor)
The human eardrum is inclined at an angle of 50 ° t o the axis of external auditory canal. The main objective of this thesis was to determine the impact of the inclination on sound transmission characteristics of external ear canal. It was observed influence of the various features of the eardrum and of the malleus weight on calculated transmission characteristics. Simple finite element model (FEM model) was created in the ANSYS program. The acoustic subsystem of the outer ear tube, elastic eardrum and solid malleus were created. The external ear canal model was modeled as one sided open cylinder which was terminated diagonally bedded with eardrum. In addition to the impact of the eardrum inclination, the influence of the eardrum elasticity and the weight of malleus on the sound transmission characteristics of external ear canal was also monitored. The eventual presence of the coincidence effect was also studied.

Foreigners in the labour market in the South Bohemian region
DUŠEK, Daniel
The aim of this work is a comprehensive overview of third-country nationals on the labour market in South Bohemian region. It is primarily focused on a comparison of the number of foreigners in the labour market in the period 2007 - 2011 according to various districts of the region. This work is also focused on identifying major employers of third-country nationals in South Bohemia and theirs experience with workers from third countries. Besides literature review dealing with the labour migration topic, the trend analysis of the third-country nationals number in the districts of South Bohemian region in the period 2007 ? 2011 was based on data from the Czech Statistical Office and the Regional Labour Office in České Budějovice. Then the set of five major South Bohemian region employers of third country workers was identified. It includes both manufacturing and services providing enterprises. The surveyed companies were selected based on the criteria of number of employed third country workers and the business sector too, so the research includes respondents from different areas of business (production of interiors for the automotive industry, metal finishing, processing industry, restaurants and transport). The structure of the interview with human resource managers or owners of these five companies about employment of third-country nationals was designed to detect reasons leading firms to employ third-country workers, the level of satisfaction with their performance, methods of recruitment foreign workers, as well as respondents' views on current legislative conditions associated with employment of third-country nationals.The obtained information was subsequently processed into five case studies, each of which deals with the description of the current situation in the employment of third-country nationals in a particular company. Based on the analysis of labor migration in South Bohemia, we can say that in the 2007 ? 2011 period, the number of third-country nationals in the labor market in South Bohemian region ranged from about 6 000 to 7 500 workers. The largest increase in the third-county workers quantity in the labour market was reported in 2008. In the following years there was a decline in the number of foreigners in the region, mainly due to rising unemployment, which was affected by the global economic crisis. In terms of ethnic composition of the of third-country workers group in the South Bohemian region, there prevail citizens of Ukraine. Other main nationalities in region are represented by Vietnamese, Russians and Moldovans. In most districts foreigners are most often represented by Ukrainians. The only exception are districts of Prachatice and Jindřichův Hradec where the Vietnamese are dominate. Five case studies with representatives of employers show that these companies where foreigners are employed mostly on blue-collar workers, are satisfied with this category of workers. Employers are especially pleased with third-country workers approach to work, willing and very satisfactory performance in their jobs. The admission of third-country nationals leading employers largely disregard Czech workers about the position, which are regarded as menial and poorly evaluated financially. The current legislative conditions associated with third country workers employment in a third country is evaluated as legitimate. However, respondents agree, that those provisions have negative impact on the continuity of the recruitment third-country nationals process.

Zajištění dostupnosti IT infrastruktury pro podporu firemních procesů
Zima, Radek ; Pavlíček, Luboš (advisor) ; Dušek, Daniel (referee)
Cílem práce je podat ucelený přehled o aktuálních technologiích sloužících k zajištění dostupnosti IT infrastruktury v podniku. Autor má zkušenosti nejen s konkrétními technologiemi a přístupy k zajištění vyšší odolnosti jednotlivých komponent serveru vůči výpadku (ukládání dat, napájení, řízení toku vzduchu, ochrana paměti, ?) , ale i se softwarovými produkty, které zajistí redundanci celého serveru. Tento přístup byl otestován i v případové studii, kde proběhla analýza stávající situace ve vybrané společnosti a nalezeny funkce poskytované jednotlivými komponentami infrastruktury. Kromě detailního zmapování situace byla nalezena i slabá místa a doporučeno řešení.
