This diploma thesis deals with computer networks which play a key role in present society. More and more demands are placed on these networks (especially on quality of services and throughput) because of fast-growing developement of services such as voice and video real-time transmissions. All the packets in typical Ethernet networks are equal. Therefore it is sometimes impossible for the application to maintain required throughput speed of a network. For this case it is useful to take some mechanisms into the consideration. These mechanisms (sometimes called QoS) are able to distinguish different types of transmissions and traffic, analyze them and then prioritize them according to some pre-defined set of rules. The most famous mechanisms are Integrated Services and Differentiated Services. The implementation of Differentiated Services is the goal of this thesis.

Tomáš ŠTÁBL Design of Gear Timing Mechanism for SI Engine MT, IAE, 2009, 62 pp., 27 fig. This master thesis is concerning the valve train proposal of the spark ignition engine for sports purposes. Antecedent to the actual proposal is the division and retrieval of the modern valve trains, the valve train acting forces description, division and description of the individual valve-lift curve parts , valve springs and the dynamic models of the valve train. In the thesis there are designed the valve lift curves with the continuous course of acceleration, valve springs and valve springs natural oscillations damper for engine Honda CBR 929RR. The dynamic analysis of valve train approach is performed.

This Diploma Thesis is aimed at exploring the potential of offset crankshaft mechanism for four cylinder inline petrol engine in terms of reducing the frictional losses of the piston group. Thesis deals with the influence of eccentricity on kinematics, dynamics and balance of the crank train. Furthermore, specific crankshaft balancing is elaborated and applied on 3D CAD model of the crankshaft. Calculation of fatigue safety factor using the advanced LSA method that takes into consideration the effect of forced torsional vibration and utilizes outputs from the FEA software (ANSYS APDL) is performed as well. Thesis also includes design of two options of rubber torsion damper mounted on the engine belt pulley and the follow-up choosing of the more advisable one.

The purpose of this thesis is to evaluate the influence of eccentricity of crank mechanism to the force between the piston and the cylinder liner for appointed crank mechanism. Furthermore the influence of eccentricity to balancing crankshaft is verified and for selected value of eccentricity is realized balance. For the construction check was realized stress analysis of crank mechanism included torsion vibration.

This diploma thesis deals with the construction and technological project of the extension of the production hall Granitol a.s. in Moravian Beroun.

In addition, an extended accompanying and summary technical report, a technical report on transport relations and coordination of oversized transport, a time and financial plan for the construction, a budget for the prefabricated skeleton, a timetable and the balance of the workers, the design of the main construction machines and mechanisms, including their time commitment , organization of the construction of the building including drawings of the construction site equipment, technological regulation for the assembly of the prefabricated skeleton and the laying of the floor formation, inspection and testing plan for the prefabricated skeleton assembly, summary assessment of the lifting mechanism selection, schematic of the assembly procedure of the prefabricated skeleton elements, protection and health at work during construction.

The focus of this work is to determine the stress of the crank mechanism of the inverted piston aircraft engine Walter Mikron III C UL from the manufacturer PARMA - TECHNIK, s.r.o. The main method of calculation is the numerical finite elements method using the program ANSYS Workbench, the module Static structural and Transient structural. The approximate indicated cylinder pressure during the duty cycle was determined in the GT-SUITE software. The partial goals are to propose possible modifications in the construction of the crank mechanism and to state the possible power reserves of the engine. The diploma thesis also briefly summarizes the history and development of aircraft piston engines from the company Walter, which developed the engine, and the line of Walter Mikron engines.
