Determination of Blood Pressure
Plch, Miroslav ; Smital, Lukáš (referee) ; Čmiel, Vratislav (advisor)
The thesis includes a general introduction to monitoring and measurement of blood pressure of horses, the design of algorithms for pressure curve detection and the calculation of respiratory variabilities in mechanical ventilation under anaesthesia. The first two chapters focus on anatomy, on characteristics of blood flow and on vascular system. Then it deals with the measurement of blood pressure, monitoring of a horse under anaesthesia and it describes particular thermodynamic parameters. In the following part of the thesis, the methods of pressure curve detection are described. The last part contains the description of an algorithm designed for detection of pressure curve of horses in the environment of the program LabVIEW. The program calculates, displays and saves variabilities of systolic pressure, pulse volume, pressure amplitude, pulse frequency, peripheral resistance and vascular expansion from the detected values.

Program for calculation of ventilation and heating in synchronous machine
Kolář, Pavel ; Ondrůšek, Čestmír (referee) ; Huzlík, Rostislav (advisor)
This master´s thesis deals with ventilation of synchronous generators with a cylindrical rotor. For the design of ventilation we apply basic physical laws in the field of hydromechanics and thermomechanics. Therefore the first chapters are devoted to these subjects. They are followed by the description of ventilation systems and a thermal net is created and solved for one of them consisting of the thermal resistance and sources. The final part deals with a program, which I developed in Visual Basic 2008 Express Edition. This program enables to calculate the ventilation and heating of individual parts of the machine after entering basic machine dimensions and losses.

Energy consumption food-factory
Hrubý, Vojtěch ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
Venting, ventilation, air-conditioning and heating serving to maintain given conditions, e.g. temperature, humidness and hygiene standards for the clean air of production and other areas bring various difficult processes provided by different complicated equipments and systems. Goal of this graduation theses is to describe these proceses and actual situation in heat energy supply in food factory conditions of Cutisin in Slavkov u Brna. The main benefit of this graduation these is the description of actual central heating solution, state evaluation and innovative suggestion for the lay-out solution of central boiler-room.

Measurement of thermal field in electric machines
Dostálek, Martin ; Vítek, Ondřej (referee) ; Janda, Marcel (advisor)
Diagnosis temperature is one of the most important disciplines. We meet it in everyday life, but it is very important for all sectors of industry. This is a measurement providing an immediate state of the measured object. Contact measurement of different temperature sensors and contactless measurement using thermal imagers. The important part is the measurement of temperature rise of induction motor. Part of the work deals with losses in the electric motor. These losses are converted into heat, which affects from various parts of the machine. Correct identification of the temperature field is important in helping to design the cooling system of the instrument. Virtually the data obtained are compared with theoretical data. We will capture part of the device and realize thermal simulations in a suitable simulation program. We propose modifying the cooling machine and the resulting data from the simulation compares.

Design of fan for electric machines
Švec, Dalibor ; Appel, Martin (referee) ; Vlach, Radek (advisor)
Aim of this bachelor thesis is to program a design calculator for different types of ventilators. Calculator should be able to display design of ventilator, draw characteristics to a graph and show characteristic numbers of ventilator. Calculation is based on characteristic numbers and theory developed especially for ventilators.

Automatic control of the gate
Harman, Ján ; Šebesta, Jiří (referee) ; Frýza, Tomáš (advisor)
The aim of my bachelor’s thesis is a automatic control of the ventilation gate. It is electronic equipment which opens and closes gate depending on input signal. The gate is driven by electromotor. Thi equipment can serve as stand alone or as a component in the bigger system controlled by computer.

Development of ventilating turbines
Křupka, Jiří ; Malach, František (referee) ; Malášek, Jiří (advisor)
This Master thesis solves a construction development of alternative modular mechanical systems for ventilation turbines. A research part of the thesis deals with the issues of transported medium (air) and ventilation, as well as functions, designs of ventilation turbines, and finally it provides an overview of ventilation turbines produced by manufacturers worldwide; these are used for ventilation of residential, commercial, industrial or agricultural structures using the natural or hybrid ventilation. A construction - design part is focused on creating 3D models of selected alternative modular adjustable ventilation turbines according to the data provided by the thesis supervisor and then on establishing a system for calculating the shapes of blades relative to the airflow for additional axial fan of ventilation turbines. For this purpose, a customized software application VENTILATOR (GUI) was developed to allow a flexible change of input calculation parameters and thus a fast modification of the curve shape in the 3D model of the axial fan blade.

Determination of Blood Pressure Parameters for Ventilation Control during Anaestesia in Horses
Horský, Martin ; Provazník, Ivo (referee) ; Čmiel, Vratislav (advisor)
The present work deals with the issue of hemodynamic monitoring of blood pressure in horses during mechanical ventilation in anesthetized horses. Result of this work is an extension to the application Datex-Ohmeda S/5 Collect, which from the pressure curve provides values needed for optimal ventilation. Initial chapter provides a general physiologic introduction. It describes the definition of blood pressure, cardiac cycle and description of the pressure curve. It also deals with the hemodynamic parameters such as pulse pressure, stroke volume and their variabilities. In the second chapter is described methodology of measuring blood pressure in horses. Both, noninvasive and invasive methods are included. The third chapter analyzes fluctuations in blood pressure during ventilation. The last fourth chapter describes the implemented extension module which is designed to monitor hemodynamic parameters of the pressure curve.
