Photovoltaic, as an alternative source of electricity
Floková, Kateřina ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The aim of this work is to provide a description and an explanation of the process of obtaining elektrical energy from solar radiation. There is preliminary mentioned an importance of producing electrical energy from renewable sources and development of photovoltaic systems. The body of the thesis is divided into seven chapters. At first, there is described the principle of transformation solar radiation into electrical energy. Then, the description of types of barrier-layer photocells follows. The types are divided according to their structure and material, which are they produced from. The third chapture is focused on production and construction of photovoltaic modules. Ways, how can be production of electricity increased, are mentioned in the fourth chapture. Advantages and disadvantages of solar concentrators are given there. In the fifth chapture there are described two basic kinds of connection of photovoltaic system. Different ways of taking-off produced electricity are related with those kinds of connection. The last chapture is the fundamental chapture of the thesis. There is given a project of concrete photovoltaic system. For this system is calculated economic return of investment included supposed increase of prices of electricity. In conlusion the author noticed events that would be given and emphasized the outcome of concerete project of photovoltaic system.

Routing among autonomous systems in Internet
Daněk, Michal ; Komosný, Dan (referee) ; Novotný, Vít (advisor)
Bachelor thesis describes the architecture of the Internet, its division into autonomous system and methods of their interconnection. Furthermore extensively describes routing mechanisms among autonomous system but also inside. More space is dedicated to routing protocols OSPF and BGP. At the end of the work is designed laboratory task for subject Network Architecture where this protocols are used.

Development control programme for autonomous fotovoltaic system
Janáč, Stanislav ; Vaněk, Jiří (referee) ; Bača, Petr (advisor)
The project considers realization system, which allows us to test six different operation modes on lifetime of accumulators. The system will be connected to computer, that will perform measurement of current and voltage and switch betwen charge and discharge modes. The measured values will be recorded in certain time intervals to computer memory. After some time these measured data will be analised and the most optimal operational mode will be set.

Autonomous Race Car Control System
Knop, Petr ; Bidlo, Michal (referee) ; Šimek, Václav (advisor)
This master's thesis describes the hardware and software implementation of autonomous control system for RC toy car. This autonomous car had the task to follow a black line drawn on a white background. Car was enriched with wi-fi for data transfer to computers and the black line is detected by the camera. The main control module was implemented using a single board computer Raspberry Pi.

Intelligent Client for Music Player Daemon
Wagner, Tomáš ; Kočí, Radek (referee) ; Janoušek, Vladimír (advisor)
The content of this master thesis project is about design and implementation of intelligent client application for Music Player Daemon (MPD), which searches and presents the metadata related to played content. The actual design precedes the theoretical analysis, which includes analysis of agent systems, methods of data classification, web communication protocols and languages for describing HTML document. At the same time is analyzed the MPD server and communication protocol used by clients application. Furthermore, this work describes the current client applications that presents metadata. In the last chapters of the thesis describes the design and implementation of intelligent client. It describes the methods of solution the implementation and solution of problems. Lastest chapters describes the testing result.

Mathematical models in epidemiology
Skopalová, Kristýna ; Štoudková Růžičková, Viera (referee) ; Čermák, Jan (advisor)
This bachelor's thesis deals with the mathematical models which are used in epidemiology. The aim of this thesis is a description and a creation of basic Kermack-McKendrick model and its analysis. The thesis is also dedicated to modification of this model and illustration on the concrete data. Last but not least, the stability of the selected models is checked in the stationary points.

System of autonomous differential equations
Benáčková, Jana ; Tomášek, Petr (referee) ; Opluštil, Zdeněk (advisor)
In his work dealing with applications, systems theory of autonomous differential equations in biology to the analysis model of coexistence of two populations. Mathematical models are described in general non-linear autonomous system of differential equations. I introduced the classification of types of singular points that are important for the following solutions to specific models. In the last part is an overview of the most famous models of the two populations (predator × prey) and specific models for the communities of invertebrate animals and mammals.

Development of autonomous fotovoltaic system
Svoboda, Luboš ; Vaněk, Jiří (referee) ; Bača, Petr (advisor)
The project considers realization system, which will allow us to test six different operation modes on lifetime accumulators. The system will link to computer, which will execute measurement current and tension and switch betwencharging and discharging modes. The measured values will record in someone time intervals in to computer memory. After someone time will analise these measured valuer and will provide optional operation mode.

Autonomous systems of differential equations - classical vs fractional ones
Glozigová, Anna ; Zatočilová, Jitka (referee) ; Nechvátal, Luděk (advisor)
Hlavním zaměřením této práce je hlubší studium a porovnání dvou oblastí diferenciálních rovnic, kde důraz je kladen na neceločíselné řády, neboť během posledních desítek let se tato oblast nejenže stala populární, ale dokonce bylo zjištěno, že standardní přístupy řešení nenaplňují očekávání, tudíž jsou vyžadovány speciální postupy. Práce také obsahuje příklady, experimenty a simulaci pro ověření, případné vyvrácení teoretických výsledků.

Automated speaker for orienteering races
Šabata, Milan ; Lázna, Tomáš (referee) ; Chromý, Adam (advisor)
This work describes an automatic commentator application for a sport called orienteering. This is an autonomous commentary on the ongoing race. The reason is to increase the attractiveness for the average viewer.Communication with humans is guaranteed using the text to speech function. The application uses inputs directly from the plant premises with the help of RACOM, where it then decides and selects interesting moments using an algorithm and a mathematical formula.
