Control of water supply for a house
Chvátal, Michal ; Richter, Miloslav (referee) ; Macho, Tomáš (advisor)
The diploma thesis deals with the design and implementation of the system that will control the water supply for the family house and its garden. The system aslo allows you to store a history that can be viewed via the web interface. The web interface also allows you to set system parameters and monitor the current status.

Numerical Integration .NET Graphical Editor
Kučera, Martin ; Kunovský, Jiří (referee) ; Šátek, Václav (advisor)
This thesis deals with the numerical solution of systems of first-order differential equations with initial conditions, using chosen one-step methods. It describes the design, implementation and testing of the application that is able to use these methods to solve the tasks entered in form of block schemes. The first part is devoted to an introduction of the topic, it provides an example of calculation of several steps using chosen methods and compares the results. A substantial part of the report deals with form and function of each block used in the block schemes editor and the transformation process of input data to data usable for creating simulation. The penultimate chapter demonstrates the accuracy of the final application. It shows solutions of a few simple examples of practical usage. This chapter also includes comparison with other simulation systems.

Measurements of the DVB-T Digital Television Receiver
Kobza, Jaromír ; Džubera, Jakub (referee) ; Kratochvíl, Tomáš (advisor)
This thesis is focused on a receiver for digital television broadcasting set-top box, mainly on its features, parameters and measurement. The important point of this work is the possibility to analyze and visualize the parallel transport stream in the same time and the solution of this problem. The principle of tuner and its measuring is deeply discussed. The text is supported with oscilloscope screenshots in particular parts of decoding stream. The set-top box is modified for laboratory measurement purpose and the transport stream output is added. An example laboratory exercise was created as a part of this work.

Optimization of manufacturing process in a selected company
Koníček, Jan ; Císařová, Michaela (referee) ; Štroner, Marek (advisor)
Bachelor thesis is dealing with optimalization of manufacturing process in engineering company Kovokon Popovice s.r.o. First part is fucused on streamlining of material flow by using circular method and triangulation method simple, from which there are three variants of workplace layouts and the most advantageous one is selected. In the next phase of optimalization, a block diagram is compiled for original prodiction and subsequently for the modified one by using machining center replacing previous machines. Capacity calculations are then calculated for the block diagrams, which express percentage use of workplace and numbers of workers needed to produce selected component. In the last part of optimalization, the requied size of the central material werehouse, number of cranes and forklifts are calculated.

MATLAB/Simulink Model Based Design Using C2000 Microcontrollers
Šoupal, Ondřej ; Ctibor, Jiří (referee) ; Pazdera, Ivo (advisor)
The aim of this thesis is to explore possibilities of rapid control prototyping, describe the concept of creating the software application in MATLAB/Simulink environment with use for development kit Texas instruments LaunchPad and create an application for DC and induction motor control in this environment. This work describes the application for unipolar/bipolar control H-Bridge of power converter for DC motor, measurement of output currents, speed and its displaying in real time using serial control interface. This thesis also desribes scalar and vector control of induction motor. All software applications with measurements are created in MATLAB/Simulink and attached to the thesis.

Electricity Meters Utilization for Advanced Monitoring and Control of the Power Distribution Systems
Bernát, Jan ; Pithart, Jan (referee) ; Drápela, Jiří (advisor)
This thesis deals with a research of static meters manufactured nowadays usable in systems of smart metering. Static meters and their functions are described in terms of their internal organization, metrology and wiring. Emphasis is given to the description of new functions (detailed measuring, calendar, disconnector, communications etc.) which could not be used with induction meters and to requirements for measuring, for expenditure control, for safety of meters and for the concept description of smart grids. In a practical part of the thesis particular systems of smart metering will be described – AMR, AMM, AMI and their advantages and benefits during their deployment. The thesis includes also a catalogue of meters usable for smart metering, which is based on available information from particular producers. The final part of this thesis gives information about a pilot project of ČEZ company and about another possible functions of smart meters which could be of use in the future.

Matrix headphone amplifier for studio monitoring
Štěrba, Václav ; Petržela, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This bachelor´s thesis describes the design of a matrix headphone amplifier for studio monitoring. The proposed amplifier is a purpose-built device to be used in studio sound recording for the mixing of multiple audio channels directed to the interpreters´or performers´ headsets. The device is basically composed of the following parts: An input section for the audio line, a mixing section which secures the setting of individual input levels for each output, an amplifier section allowing the setting of the output signal level for each output, and an output section enabling the connection of headphones. The equipment utilizes a connection to a multi-channel audio signal bus; this bus also provides for remote power supply to all the connected devices. The solution described in the thesis can be defined as alternative monitoring that facilitates quick and easy connection of a required number of monitoring points (in other cases, such monitoring is usually realized by means of individual small mixing consoles).
