Detection of eyes in facial images by means of Hough transform
Janovič, Tomáš ; Čmiel, Vratislav (referee) ; Walek, Petr (advisor)
The thesis discusses the detection of eyes in facial images by means of Hough transform. It is dedicated in the necessary preprocessing of the image, especially in edge detection. Further it discusses the Hough transform itself and describes the method for detection of simple shapes such as lines and circles. Subsequently, the thesis illustrates the implementation of Hough transform for detecting circles along with an algorithm evaluating Hough space. The last part contains the results and an assessment of detection algorithm along with a discussion of utilization the Hough transform for detection of eyes in facial images.

Project of Backup Power Source for the Heating Plant Červený mlýn
Nagy, Pavel ; Vrána, Michal (referee) ; Jára, Jaroslav (referee) ; Orságová, Jaroslava (advisor)
This thesis describes a design of backup power for heating plant Červený mlýn, Teplárny Brno, a.s. The backup power would be used in case of loss of power from the electricity grid, especially in the case of so-called "blackout". Backup power would supply only necessary systems of this heating plant, such as spinning turbines before stopping, control room power supply and lighting. Particularly designs of accumulator, flywheel and diesel generator are discussed. The main aim is to choose the optimum solution.

Cars Electric Drivetrain
Guráň, Radoslav ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This bachelor`s thesis is a specialized research, focused on electric drive units of personal vehicles. The thesis is divided into seven main parts. The first part deals with alternative fuels. The second part divides electric drive units into various sections and describes the history of an electric vehicle. The third section focuses on electric vehicles with a battery and analyzes electric motors and energetic power banks. The fourth and fifth part of the thesis focuses on electric vehicles with fuel cells and vehicles with a hybrid drive. The sixth chapter is devoted to the developing trends. The last section discusses the ecology of vehicles with an electric drive.

Elimination of Discontinuity Supply of Electric Energy from Renewable Energy Sources
Radil, Lukáš ; Goňo, Radomír (referee) ; Braciník, Peter (referee) ; Mastný, Petr (advisor)
Doctoral thesis deals with domain of electric energy storage. It seeks to define the methods of accumulation, which can be used in industrial applications and define the conditions for the use of storage systems in electric power systems with extended penetration of renewable energy sources. In the context of current developments in this field is analyzed detail one of the perspective storage systems - Vanadium Redox Battery (VRB). One of the outcomes of this work is economic and energy analysis of storage systems, which are conceived with a disproportion between production and consumption of energy. The work was supported by the Centre for Research and Utilization of Renewable Energy (CVVOZE) no. CZ.1.05/2.1.00/01.0014 and research project no. FEKT S-11-9.

Low-Voltage Traction Drive with a Fuel-Cell
Hejkrlík, Jan ; Singule, Vladislav (referee) ; Richter, Aleš (referee) ; Vorel, Pavel (advisor)
The main aim of this work is a development of electric car. This car has fuel cells as a primary source of electrical energy which will be performed with regard to the maximum roll-out and to maximize the efficiency of hydrogen conversion into electricity. The first part is dedicated to the concept of drive as a whole, the second part is dedicated to solving vehicle dynamics. The third part describes the design of mathematical models of drive components. Part four gives the results of simulations of traffic on the route at different ways of managing fuel cells and various vehicle speeds.

Charger for small accumulators
Dvořák, Pavel ; Zeman, Václav (referee) ; Kolka, Zdeněk (advisor)
Work will address the characteristics of small batteries. They are described types of charging process, charging time and charging currents, depending on their effectiveness. Great attention will be directed to draft Chargers, working in the area of continuous or discontinuous modes. Furthermore, the calculation of individual components and their influence on the running drive. The charger will be simulated by PSpice program and powered photovoltaic. Work will focus on the maximum efficiency when the incident light intensity. With related setting maximum efficiency and maximum power tracking using microprocessor-controlled detention. The charger will detect the input voltage, battery voltage and current. Depending on these values will be changed duty cycle PWM.
