The thesis introduces thorough analysis of current approach towards margin squeeze practice, an abuse of dominant position by vertically integrated entity. For proper categorization, definition and understanding of the basic assumptions behind the strategy of margin squeeze and its application, the paper presents necessary conceptual apparatus. Further the paper deals also with regulatory framework of abuses of dominant position, national as well as international. In the practical section the paper introduces margin squeeze strategy within telecommunication industry and its regulatory framework in the Czech republic and brings recommendations for ex-ante margin squeeze testing in relation with current European regulators policy updates following the dynamic technological development of the industry.

The squeeze-out has been introduced into Czech law in June 2005. Until now, 780 squeeze-outs have been executed, during that almost 22 billion CZK have been distributed among minority shareholders. The rights of different shareholders groups are in conflict during squeeze-out which makes the whole process quite controversial. Minority shareholders' basic right to participate in the company, which is usually accompanied by the profit participation right is taken from them. On the other side, the major shareholder gets the chance of more effective company governance or the chance to sell the company in the merger for much higher sale price. The whole process is honest only if the minority shareholders receive an appropriate compensation for the termination of their participation in the company.

This master’s thesis is dealing with low-fatigue behavior of magnesium alloy AZ61, prepared via squeeze casting method. The main aim of this work was to obtain the basic mechanical properties as well as the low cycle fatigue data. Additional metallographical evaluation of microstructure and fractographical analysis after fatigue tests was made.

The purpose of this diploma thesis is an evaluation of die-castings porosity, eventually the evaluation of seats with local squeeze in connection with their mechanical and structural properties. The swatches of alloy AISi9Cu3 were taken from the engine block made by Škoda Auto Company, Mladá Boleslav. To the evaluation and the comparison of the results there were used value of porosity with own measure and other student´s thesis of Brno University of technology. Sets of mechanical and structural properties were selected, evaluated and tested by statistical programs.

The aim of this diploma thesis is to analyse the porosity of die - cast cast that were made of the alloy AISi9u3 in iron-foundry Skoda Car Mlada Boleslav. The analysis and the sample comparisons are based on my own measurements and are also connected with previous diploma thesis which deals with that issue and was drawn up at Technical University in Brno. All measurements were statistically tested.

In der vorliegenden Arbeit wird ein neuer mikromechanischer Drehratensensor nach dem Stimmgabelprinzip vorgestellt. Die mechanische Sensorstruktur wird mit Hilfe der Bulkmikromechanik hergestellt und arbeitet nach dem elektrostatischen Wirkprinzip. Um große Amplituden zu erreichen, werden mechanische Koppelschwingungen ausgenutzt. In der Arbeit wird allgemein auf Entwurfsprozeß, Modellierung und Simulation mikromechanischer Strukturen eingegangen. Es wird die gemeinsame Lösung gekoppelter Felder mit Hilfe der Netzwerkmethode (PSpice) und die partitionierte Lösung mittels Online-Simulatorkopplung (ANSYS–PSpice) vorgestellt. Ein wesentlicher Bestandteil der Arbeit ist die Untersuchung der viskosen Luftdämpfung mikromechanischer Elemente mit engen Bewegungsspalten. Es werden verschiedene Möglichkeiten der vereinfachten Berechnung gezeigt.

Investigation of material behaviour in a squeeze flow geometry provides an impor- tant technique in rheology and it is relevant also from the technological point of view (some types of dampers, compression moulding). To our best knowledge, the sque- eze flow has not been solved for fluids-like materials with pressure-dependent material moduli. In the main scope of the present thesis, an incompressible fluid whose visco- sity strongly depends on the pressure is studied in both the perfect-slip and the no-slip squeeze flow. It is shown that such a material model can provide interesting departures compared to the classical model for viscous (Navier-Stokes) fluid even on the level of analytical solutions, which are obtained using some physically relevant simplificati- ons. Numerical simulation of a free boundary problem for the no-slip squeeze flow is then developed in the thesis using body-fitted curvilinear coordinates and spectral collocation method. An interesting behaviour is expected especially in the corners of the computational domain where the stress singularities are normally located. Unfor- tunately, numerical results reveal some fundamental drawbacks related to the physical model and its possible improvement is discussed at the end of the thesis.
