Indicator of Thunderstorm
Studený, Pavel ; Sekora, Jiří (referee) ; Chmelař, Milan (advisor)
The aim of this Bachelor thesis is a theoretical analysis of thunderstorms, lightning and their detection. The theoretical description then gradually moving towards designing their own detector. The detector will operate so that when a lightning activity captures pulses which generate lightning. Lightning will register using the attached counter. After the storm could be due to information from the counters to evaluate how strong the storm was.

Doppler blood flow detector
Klügl, Jan ; Čech, Petr (referee) ; Rozman, Jiří (advisor)
This bachelor's thesis is engage in suggestion of nondirection doppler blood flow detector with unmodulated carrying wave. At first the thesis describes indicator's principle of working and mention the systemic proposal for working frequency and intensity of ultrasound. Later in detail describes individual blocks, which are the detector consist of. At every block of system is mentioned the diagram of connection and values of components, which are ascertained from calculation, simulation and recommendation of producer.

Smart food polymer layers
Valíková, Michaela ; Kovalčík, Adriána (referee) ; Veselá, Mária (advisor)
Smart packaging represents a group of packaging with great potential when used in the food industry. Active packaging can have a positive effect on the condition of stored food and smart packaging can inform consumers about the condition of stored food. In the theoretical part, a search was made on the topic of packaging in the food industry, with emphasis on active and intelligent packaging, including the legislative framework. The substances from which smart packaging is made have been described. In the experimental part, partially water¬insoluble polymer layers were prepared from gelatin, glycerol, crosslinking agent and anthocyanin extract. Glutaraldehyde or tannic acid was used as a crosslinking agent. Anthocyanins were obtained by extraction from red cabbage. The total concentration of anthocyanins in the extract was determined by the difference method. For prepared layers, their water solubility was measured and the colour response to the pH environment was evaluated spectrophotometrically. The stability of the layers over time was also monitored. It was found that the prepared layers are able respond to changes in pH.

BSC Method and Possibilities of Its Application in IT Domain
Navrátilová, Kateřina ; Zámečníková, Eva (referee) ; Květoňová, Šárka (advisor)
Bachelor's Thesis deals with utilization of Balanced Scorecard method. The method measures a performance of an organization using financial and nonfinancial measures, which are substantial for increasing performance and efficiency. The thesis contains summary of methods used for evaluation of efficiency of information systems. A description of Balanced Scorecard is included in association with specification and description of application's implementation. The application is used for creating and administrating the strategies of Balanced Scorecard method.

Industrial state indicator
Růžička, Zdenek ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
Diploma work deals with industrial display systems, indicators and their proposal. These systems are used everywhere that is necessary to mediate transmission of information. Own proposal of indicator is very specific and depends on given application and used display. In practice there is possible to use a few types of displays but in this diploma work there are used only sedmisegmental and matrix. Common component of proposal is microcontroller. No less significat and important part of the proposal is a choice of interface and communication protocol. The correct choice of hardware that is completed with software we will obtain complete status indicator.

Thunder detector (lightning indicator)
Trávníček, Tomáš ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
The aim of this Bachelor’s thesis is to gain knowledge from the storm, it’s manifestations, detection through these speeches and then using this knowledge gained to design a simple indicator of thunderstorm’s (lightning), which will operate on the principle of counting flashes. The drafting of the principles and use of simple electronic component’s. The result of all this work is making a functional indicator of the sample.

Automatic Trading System for CFD Markets
Novák, Milan ; Novotná, Veronika (referee) ; Budík, Jan (advisor)
This thesis deals with design, optimization and testing of an automated trading system intended for trading CFD contracts. The strategy is based on a combination of a moving average and a custom indicator, which gives signals based on convergence of signals of other monitored indicators. The designed automated trading system also contains a simple, but efficient money management. It is responsible for risking a constant portion of current account balance on each trade. The thesis continues with comparison of three ways to optimize chosen input parameters and comparison of performance of the strategy for ten tested market symbols.

Indikator position behind the wall
Pecha, Václav ; Marcoň, Petr (referee) ; Szabó, Zoltán (advisor)
The work sums up the basic measurement principles for different kinds of searching devises. It deals with measurement using resonance. The feature of resonance and measurement techniques are described to set the location of the radiating circuite. The work contains the design of a locator of position behind a wall itself as well as the concrete switch connection, schema and description of receiver and emitter in the circuit.

Proposal of Software Improvement Support for a Trading Strategy in Commodity Markets
Levek, Petr ; Kotlík,, Josef (referee) ; Škapa, Stanislav (advisor)
The Bachelor work is focused on proposals to improve software support and the efficiency of investment in commodity exchanges worldwide. The aim is to propose software improvements for selected software used for trading. Improvements will be made on the basis of analysis and comparison, the currently commonly used traders software for trading on world stock exchanges, with a focus on finding and proposing modules that improve the strategies used during trading. Based on the introduction and the use of these improved modules, that are currently not available, will increase efficiency of work for traders and reduce potential risks of investments used.

Photocatalytic sensor of oxygen
Filipi, Denisa ; Kubáč,, Lubomír (referee) ; Veselý, Michal (advisor)
This bachelor thesis deals with the optimization of inks for the preparation of photocatalytic oxygen indicator.The aim was to prepare a photocatalytic oxygen indicator with sufficient colour change after photoreduction and after reverse photooxidation.The indicator is based on semiconductor particles (TiO2), a sacrificial electron donor, a redox dye and a polymer which serves as a binder. The effect of the polymer used on the appearance of the prepared layers deposited on the PET film was investigated. The effect of the concentration of sacrificial electron donor on the rate of photoreduction (transition to the colourless leuco form) and reverse photooxidation of the indicator (transition of the leuco form to the coloured form) was also studied. Based on the study of the indicators, the rate constants for photoreduction and photooxidation of the prepared indicators were determined.
