This diploma thesis analyzes the effects of various parameters of vane profile and position of VNT mechanism on the size of aerodynamic force which acts on the vanes and on the position of neutral axis of the vane. A CDF simulation was created to do this analysis, and the results of the simulation were evaluated. Thesis also deals with turbochargers in general and with other methods of their regulation.

The main objective of the thesis is to verify the hydraulic inducer designs and to determine its effect on the cavitation characteristics of the pump. To increase the suction capability and cavitation resistance, the inducer is placed in front of the impeller centrifugal pump. Its role is to protect the impeller against the cavitation. The literary part of the thesis analyzes the issue of cavitation, its origin, development and termination of the cavitation bubble with so-called implosion. Special attention is devoted to describtion of cavitation effect occuring at the hydrodynamic pumps. In the theoretical part, the author is then dealing with the general principles and so far used approaches to the inducer design. The practical part of the thesis describes the process and the derivation of own designs of cylindrical inducer. The aim of the used, unconventional approaches to the inducer design is to achieve a constant pressure field and specific energy of the inducer design output. Partial variants of inducer blades design geometry are tested by the controlled calculation with CFD.

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.

Title: Possibility of using Aqua Therapy for shoulder stabilization The aim of this thesis was to refer to possibility of using Aqua Therapy in Physiotherapy, especially to possibility of using Aqua Therapy for shoulder girdle stabilization. The thesis is supplemented by pilot study, witch compare activity of scapula stabilizing muscles dutiny movement on land with Thera-Band and in water with different equipment. Activity of selected muscles was documented and compared using surfaře electromyography. The results indicate flatter curve of selected muscles activation and their ko-contraction during movement in water condition. The results also refers to no significant differences in muscle activation in water and on dry land. Water exercise demonstrated in this study can by considered to be effective for improvement of scapular stabilization. Keywords: Aqua Therapy, water exercise, electromyografy, water EMG, scapular stabilization

A muscular co-operation change was observed at exercising intent on improvement of a scapula dynamic stability. In the study there were ten individuals participating in a specific resistance exercise for a period of seven to nine weeks. The cooperation of scapular muscles was evaluated in stand - by (tilt test) and investigation the stereotype of arm abduction, visually and by the help of a surface polyelectromyography. A distinct improvement of a scapula dynamic stability occurred at three observed objects. Powered by TCPDF (www.tcpdf.org)

The content of study is related to reducing the production times of milling of aluminum component of vacuum pump. The primary aim of the thesis is to experimentally verify the proposed cutting conditions when milling the rotor blades and then evaluate them according to predetermined parameters. The output is reducing machining time with respect to cost, tools and machine.

This master thesis deals with steam turbine blade attachment. Main goal is to perform strength analysis of the given geometry under static and cyclic loads by FEM and software ANSYS. Every particular model is described separately with mentioning of the problems which had to be solved. To create model of material, the tensile tests has been performed and results has been evaluate. There were planned and performed the low cycle fatigue tests to create a model of ultimate states which is used to evaluate the fatigue life of the attachment. Results of the nonlinear FEM analysis is discussed and some improvements of the geometry has been proposed to achieve better state of stress. Finally, the plan of future work has been proposed.

Name: The Effect of Facilitating Kinesio Taping of lower scapula fixators on pain threshold of trigger points in the m. trapezius pars descendens Objectives: This study is a pilot study. The goal of this study is to determine effects of Facilitating Kinesio Taping of lower scapula fixators on painfulness of trigger points in the m. trapezius pars descendens. Methods: The study took place in a private medical office with thirteen patients. All of these patients were physically examined using standard tests of physiotherapy. Patients were measured using a pressure algometer to assess trigger points as painful. They reported the intensity of pain on VAS. The places of measurement were trigger points one and two in the muscle according Travell and Simons. Data were analyzed using the statistical program SPSS 15.0 and Microsoft Office Excel. Results: This study had three hypotheses. In the case of the first hypothesis, I concluded that KT has an effect on the pain threshold and its application will reduce the pain threshold in m.trapezius pars descendens. Statistical significance was the value of p = 0.03 and p = 0.011, the value of material significance (101.31 kPa and 106.7 kPa) confirmed my theory that after KT will increase the pressure of 100 kPa in the TrP1 and TrP2. In the second hypothesis, it...

This master thesis deals with axial dendritic suspension of steam turbine rotor blade. The initial shape of the suspension was design on the basis of available data. There was performed stress-strain analysis of this shape and most dangerous spots were picked. There were made several geometrical changes of the shape of suspension. Their affection on stress-strain responding of the suspension was examined. The best shape was chosen which was used to perform analysis of infinite life according to ASME code and due to loading low cycle fatigue analysis. According to results of low cycle fatigue analysis the maximum loading was established. At the end of this work the further steps were suggested.

This thesis describes design of new circumferential blade attachment on last grade of steam turbine and following stress-strain analysis by FEM with static and cyclic loading. It was created two new design of geometry, which were created based on existing and operating constructional solution of oblique double T blade attachment. It was made stress-strain FEM analysis on original design of blades. Its results served to realize change of construction. Their target was increase load capacity and service life of new types of blade attachment.
