Evaluation of gas flow in the scintillation detector at different profiles and sizes of holes in the screens that have shaped the network
Truhlář, Michal ; Špinka, Jiří (referee) ; Maxa, Jiří (advisor)
This work deals with the flow of gas in the scintillation detector. Thesis describes the function of an electron microscope, the composition, distribution and development of microscopes from the earliest to modern. The work also includes familiarization with SolidWorks 3D modeling in which is the electron microscope modeled and Cosmos FloWorks in which they are carried out simulations of gas flow. The paper is focused on the flow of gas in various shapes of the screen and various pressures in chamber of specimen. The results of the analysis of both apertures variants are compared with the request to minimize the pressures in the trajectory of the secondary electrons of well as in the chamber of specimen.
Biologically Inspired Methods of Object Recognition
Truhlář, Martin ; Hradiš, Michal (referee) ; Juránek, Roman (advisor)
This document describes a method for biologically inspired pattern recognition. Furthermore, it explains the process of image processing and various stages of information extraction for classification. Support Vector Machine method is used for classification, but there are other classification methods explained. It explains how to test and work with the method itself. Results for each model set of classifiers and their advantages and disadvantages are summarized in the conclusion.
Steam boiler for straw 10t/h, 320°C
Truhlář, Marek ; Kól, Přemysl (referee) ; Skála, Zdeněk (advisor)
The aim of this thesis is design a grate steam boiler for burning straw with an output of 10 tons of steam per hour. The produceds team has parameters 320 °C, 3,2 MPa. For a given fuel (fytomass) is calculated stoichiometric calculation. The following is the calculation of the heat balance of the boiler including the determinativ of thermal efficiency. The fuel used, the required parameters of steam and feed water temperature are designed individual convective surfaces and dimensions of the boiler. The boiler design includes drawings.
Modeling HF diode in Comsol Multiphysics
Truhlář, Michal ; Pokorný, Michal (referee) ; Raida, Zbyněk (advisor)
This work brings understanding effects in semiconductor diode by rise P-N junction. Attention devote to suggested high frequency semiconductor diode in program Comsol Multiphysics 3.3.Atention is concentrated to optimization model of diode so as volt-ampere characteristic resembles to real characteristics of diodes. Is tried to find a solution to entourage P-N devolution, where this program sensitive on changes geometry’s barriers of these is different types P-N. In work is summary of treatment and advancing by divining and by optimization of high frequency diode. First part describes semiconductor diode like component used in the electrotechnics, which explains rise, descriptions, using and types of used diodes. Second part includes progress of scaling concrete semiconductor high frequency silicon diode. In this work is braining to optimization model of diode to real and research parameters, which influence her descriptions. In last part of my bachelor’s work was created a simple program in Matlab for global optimization. This program by connected with model of diode and check up possibilities of optimizations their parameters
Renewable resources of energy in Czech republic
Truhlář, Marek ; Fortelný, Zdeněk (referee) ; Chroboczek, Libor (advisor)
The content of this bachelor study is a technical recherche of the renewable resources of energy in the Czech republic. In the first part of the study there are described individual kinds of renewable resources of energy. The principle, the usage potential in Czech republic, some advantages and disadvantages about every topic are mentioned. In the second part the study is focused on usage of solar energy in the Czech Republic. The present state of used barrierlayer photocells and solar collectors is decribed in this part. In the last section there is a description of a photovoltaic power station in Otrokovice.
