This diploma thesis deals with the tracking of the maximum power point for photovoltaic panels and the methods used to achieve it. On this basis, two methods were designed and programmed and subsequently tested on three types of photovoltaic panels. In conclusion methods were appraised.

This thesis deals with the examination of damper characteristics and influence of individual parameters on vehicle handling, primarily with the use of computer program Matlab Simulink.

The purpose of the diploma thesis is to establish on survey of swirl pump from previous years and his optimization via which is suggested the second degree of synchronous pump whereas they should work together like a total artificial heart. Hydraulic and constructional proposal is solved. Conception is realized experimentally also with help of CFD calculation, results are compared with each other.

This diploma thesis deals with the displaying process evaluation from the resolution capabilities of the ultra-sonic probe point of view. As a part of the thesis a method for measuring the response from point spread function (PSF) and method for measuring the response from linear spread function LSF were designed. Collected data were processed in the Matlab environment. Basic evaluation parameters of the space resolution capabilities were set and used – axial, lateral and traversal resolution.

This master’s thesis’s target is to introduce the basic findings about single-phase asynchronous motors, their derivation from three-phase motors and the basics of a computation process and a concept of a single-phase asynchronous squirrel cage motor. The inbeing of this concept and the computation is created by classical processes for three-phase motors with a low voltage, 50 Hz.

Subject of this thesis is introduction to questions of stepping motors control. The thesis characterizes basic principles some types of stepping motor, their features and control methods. These knowledges are consequently used for proposition of controlling circuit for driving stepping motor using microcontroller.

Tato práce se zabývá slunečním zářením, které je jedním z možných zdrojů obnovitelné energie. Hlavnímy body práce je seznámit se s problematikou fotovoltaiky. Sestrojení poloautomatizovaného měřícího pracoviště díky němuž obdržíme reálné I-U a P-U charakteristiky solárního panelu. Dalším bodem je sestrojení programu v programu Vee Pro 8.0, který tyto charakteristiky simuluje v programu. Cílem je zjistit charakteristické konstanty pro daný solární panel.

The goal of diploma these is ‘Calculation of frequency-admittance characteristics from measured patchlamps dates’. Calculation is made on the basis of study of mentioned problematic measure ion current cell membrane by patch-clamp method and its using for measure frequency-admittance characteristics. After it selected method of calculation was realized in software calculator Matlab.

This thesis deals with pulse charging lead acid batteries. The theoretical part provides the basic electrochemical reactions that take place in the lead pack, then this section discusses important parameters of lead-acid battery, its structure and distribution of the various types depending on the application. The next section describes the theory of charging lead-acid battery. The practical part deals with constructing experimental cells, which are then tested. The subject of the experimental execution and optimization of pulse charging modes in order to find a suitable pulse mode, which reduces the duration of charging, while significantly shorten the life of lead-acid battery.

The master's thesis deals with compressor turbochargers used for supercharging of combustion engines. The aim of the thesis is feasibility study of compressor surge limit simulation. First of all the principle and purpose of supercharged combustion engines is described and the compressors' types using for supercharging are mentioned as well. The main part of the thesis is focused on flow instabilities and their influence on compressor operating zone. There are mentioned some possibilities of operating zone extension. The practical part comprises the simplified computation of a one stage of centrifugal compressor and flow analysis by means of CFD simulation.
