The purpose of this diploma thesis is comparing the quantity of porosity in die-cast aluminium casting with using simulation. The cast engine blocks were made by high pressure die-casting and a local squeeze casting (LSC) technology. There was also examined the relationship between porosity and mechanical properties of castings. There were evaluated and compared the results of my own measurements with data from previous students theses at the Faculty of Mechanical Engineering BUT. All data were tested by statistical tests. The comparison of simulation results and experimentally measured values was found a good programme-ability to simulate and estimate porosity.

The aim of this Master’s thesis Vibration Propagation Analysis of Coupled Structure Acoustic Space is to analyze vibration propagation in combustion engine, from combustion space through solid structure to fluid surroundings. Then analyze the noise increase as pressure changing in fluid space around the solid structure. There was made a analyze of single piston engine in different frequency and piston location. A simulation of distribution of a pressure waves was made in an ANSYS application.

The goal of this master´s thesis is designing power plant with gas turbine of 50 MWe power output for the site. It includes appropriete choose of gas turbine and its simplified termodynamic calculation, designing the thermal diagram and its calculation, for the parameters complying with nominal temperature of outside air, layout design, annual energy and mass flow results, savings of combined heat and power, intended at this application and economic evaluation of investment.

Size and distribution of mount deformation are the main topics discussed in this thesis, using different static loading. The thesis’ primary focus is to show how deformation and stress of the engine block with cylinder liner are affected in the assembly order of the cylinder head. The calculation and evaluation of the solution are calculated by using method finite element, software Ansys. In addition other methods are discussed which can also measure the deformation of the engine block.

The Master`s Thesis deals with design and construction of a valve block for a hydrostatic recuperative module of a vehicle with a direct application on pneu tyred roller AP 240H produced by the AMMANN company. The thesis aims to analyze recovery functions of the valve block in several operating modes of the roller, followed by a selection of the right hydraulic components from the perspective of predefined parameters and pressure differences. Design specifications are based on measurements and mathematical simulations on the experimental stand. The experimental stand for this application has been developed at 1:4 scale as compared to a real vehicle. The thesis includes also design of the supporting console for the module on the frame of the vehicle. The Master`s Thesis is a part of project EUREKA with cooperation Bosch Rexroth.

V systému s kódy zbytkových tříd je základem skupina navzájem nezávislých bází. Číslo ve formátu integer je reprezentováno kratšími čísly integer, které získáme jako zbytky všech bází, a aritmetické operace probíhají samostatně na každé bázi. Při aritmetických operacích nedochází k přenosu do vyšších řádů při sčítání, odečítání a násobení, které obvykle potřebují více strojového času. Srovnávání, dělení a operace se zlomky jsou komplikované a chybí efektivní algoritmy. Kódy zbytkových tříd se proto nepoužívají k numerickým výpočtům, ale jsou velmi užitečné pro digitální zpracování signálu. Disertační práce se týká návrhu, simulace a mikropočítačové implementace funkčních bloků pro digitální zpracování signálu. Funkční bloky, které byly studovány jsou nově navržené konvertory z binarní do reziduální reprezentace a naopak, reziduální sčítačka a násobička. Nově byly také navržené obslužné algoritmy.

Master's thesis treats of implementation of big block file system for FreeBSD operating system. The introduction of this document is dedicated to theoretically analysis, which is oriented on history, sense and usage of file systems. Next chapter describes the architecture of UFS/FFS file system. Implementation part starts with introducing design of new file system, which was isnpired by MSDOSFS file system. Last part of this thesis presents implementation of file system with great emphasis on problems, which can happen during programming.

The topic of this thesis is a new school facility of Leisure time center Kostka. The Leisure time center is a deteched two-sotrey building on mildly sloping land. The building is basementless. The Leisure time center is located next to the kindergarten and elementary school.The layout includes a building of 11 classrooms and is designed for 163 children. Perimeter, internal bearing and non-bearing walls are designed from brick blocks. Ceilings are made by using prestressed ceiling panels. The building is roofed by a single-flat roof and walkable intensive green roof.

The theme of this diploma thesis is a project of the polyfunctional building with offices and sportbar for business activities. The projected building should be located in the village Jemnice in the street ,, Budějovická“ It is a four-storey house with partial basement, which is situated on midly sloping land. The house is built of brick blocks POROTHERM. The ceilings of the house are made out of fundamentals roofs Miako. The partitions are combination of brick systems POROTHERM and Knauf plasterboard partitions. The roof is slant double-coating covering of systém Fatrafol – S810.

Foreign policy of Czechoslovakia in 70's and 80's depended completely on the policy of the Soviet union and its promoted ideology. The Czechoslovak socialist republic preserved the narrowest relationship with the Soviet union and its sattelite states in Eastern Europe, while the relationship with the western countries oriented to co-operation with the United states, was very cold and was beeing restored very slowly and gradually. The developing countries, especially those heading to a socialist establishment, had a special position in Czechoslovak foreign policy. Especially these countries benefited from Czechoslovak aid such as financial, military or material support. Another way Czechoslovakia implemented its development aid was offering scholarships for university students. The purpose of this form of aid was to contribute to the progress of developing countries, most of whom gained independence recently. Simultaneously the policy pursued another aim - to spread the socialist ideology and the influlence of the Soviet union around the world. Hundreds of foreign students studied in Czechoslovak universities every year during 70's and 80's. Most of them came from so called developing countries. Foreign students came from various countries of the world, various cultures and therefore they perceived...
