Goal of this master´s thesis is to experimentally analyse air jet from ventilation outlet of a passenger car dashboard using smoke visualization and to describe this air jet. Air flow was set at 30 m3/h according to requirements from Škoda Auto s.r.o. from previous experiments on a similar ventilation outlet. First type of measuring rig which was developed for previous experiments was disassembled and replaced with a new modern measuring rig which is supposed to be used for next visualizations and experiments. Visualization was performed using smoke method and laser light plane. Air jet was photographed for five defined ventilation outlet adjustments and that for a jet to free space and for a jet flowing along a wall. The wall represented a front left door of a car. Results were processed by computer and presented as pictures and tables. Resulting angles were transformed to the main coordinate system of a car. Ventilation outlet functionality with respect to the air distribution in a car was evaluated afterwards.

Within modern frequency structures, the filter frequency region of up to 10 MHz constitutes a promising research topic that currently attracts intensive attention of specialists interested in the problem. The main reason of this fact consists in that the rapid development of modern technology allows the production of innovated structures of the analog frequency filters required in the defined band. In this context, however, it is also necessary to refine the methods applied in the synthesis and optimization of these structures; such improvement should be carried out with respect to fundamental properties and usability of today's active elements (operational amplifiers with voltage feedback whose Gain Bandwidth Product ranges within units of GHz, operational amplifiers with current feedback, conveyors, transimpedance operational amplifiers). In this thesis, active blocks of synthesis inductors (SIs) and frequency dependent negative resistors (FDNRs) are examined in detail, and the author provides novel formulas to define the basic parameters of the dual circuits. Due emphasis was placed on optimizing the basic building blocks of the second order and defining the variation of their properties caused by the addition of modern active elements. The blocks were analyzed and modified in view of their possible use in higher-order circuits. For active filters of a higher order, simulations were performed to indicate the actual sensitivity of the cascade and non-cascade ARC structures. The following phase of the research comprised mainly the designing of several filters, and this activity was further completed with the verification of the methodology for the synthesis and optimization of higher-order loss ladder filters with modern active blocks. Special attention was paid also to the methods enabling the optimization of such filters, which are invariably based on RLC prototypes. In order to verify the theoretical conclusions, the author materialized a large number of sample optimized filters and measured their parameters. The closing section of the thesis describes the use of the filters in specific applications.

This thesis is focused on behavioral modelling of active elements with independent multi-parameter electronic control using comercially available components. In a first part of the thesis, CVDIBA, CVDOBA, CVCC and OC elements are discussed. The functionality is verified by simulations using OrCAD PSpice. Used components are diamond transistor OPA860, variable gain amplifier LMH6505, differencing amplifier AD830, low distortion differential driver AD8138, current conveyor EL2082 and current mode four quadrant multiplier EL4083. Four active elements are further built on PCB and measured. Some applications like low pass filter, high pass filter, all pass filter and reconfigurable filter.

This thesis deals with fully differential and pseudo-differential frequency filters. Significant emphasis is placed on the characteristics of common-mode signal. Further, the text deals with the design issue of fully-differential structure and transformation of non-differential to pseudo-differential structures. In the thesis one non-differential structure, one fully-differential and three pseudo-differential structures are proposed, one of them working in current mode. The thesis also describes the analysis from the perspective of non-ideal properties of the active element of two circuit solutions, which is trying to find the optimal solution. In each case, functionality of new solutions is verified by simulations and in several cases also by experimental measurement.

The thesis follows the development of the methodology of left-handers's writing, teacher's usage of the knowledge of methodology in a practice, researching the materials aimed in left- handness dedicated to teachers and parents, describing statements and opinions of the concrete primary teachers on left-hander's methodology. The thesis consists of the theoretical part and the empiric part. In the therotical part there are defined terms laterality and dominance, the development of the methodology of left-hander's writing since the year 1967 when this type of writing was legalised in the Czech Republic. The possibilities of getting information about the problematic of left-handness are summed, including books and trainings for primary school teachers. Finally, available equipment for left-handers is introduced. The research combines two methods - questionnaire and interview. The quantitative research is supposed to come up with the concrete percentage of left-handed pupils and with the general knowledge of teachers connected with methodology of left-hander's writing. The qualitative research was made by the form of interiewing teachers and Ivo Vodička. The aim of the thesis is to find out the way how to train teachers effectively based on researched information.

The goal of this thesis is to show the life and functioning of the Senate of the National Assembly of Czechoslovakia. The upper house of the Czechoslovak Parliament functioned between 1920 and 1939 after which it was officially dissolved during the Protectorate of Bohemia and Moravia. In the concerned period, the chamber was gradually saw 444 lawmakers of seven different nationalities. The biggest number consisted of Czechs and Germans. The functioning of the Senate is analyzed from multiple angles. First the debate accompanying the establishment of a second chamber before the adoption of the new Constitution in 1920 is analyzed. Attention is also paid to the period debates and unrealized proposals for a Senate reform at the end the 1920's, linked to the proposed creation of the Economic Parliament. Also shown is the proportional representation electoral system used for elections to the Senate. The results were reflected in a large number of political parties with low electoral gains, which in turn hindered the creation of a stable political environment. The thesis considers the party, ethnic, social, intellectual and oratory activities of individual senators. The lives of some of the lawmakers who held seats in the upper chamber in the First Republic and were negatively affected by the German...

The diploma thesis deals with the use of recycled asphalt with aggregate in a hydraulically bound mixtures. The mixture is determined in the base or sub-base course of the pavement. The theoretical part of the diploma thesis describes the base course of the pavement, the production of recyclates from construction demolition waste, the acquisition and processing of recycled asphalt, the road reuse and recycling. The thesis is enriched by a contribution from the implementation of recycled asphalt laying into the base course of the communication company SKANSKA a.s. and ČNES a.s. The next chapter describes detailed experiences with recycling abroad. The thesis also contains a description of laboratory tests, which are important for evaluating the properties of mixtures with recycled asphalt. The practical part verifies the suitability of the mixture of recycled asphalt and aggregate for the road surface by testing the transverse tensile strength, compressive strength and frost and water resistance.
