The influence of alcaline accumulators loading on their parameters
Čech, Ondřej ; Vrbický, Jiří (referee) ; Sedlaříková, Marie (advisor)
This master's thesis deals with alkaline battery characteristics and it has special consideration of nickel-cadmium cells. There are three main experimental parts in this paper. First one is concerned with positive electrode materials properties and is aimed to investigate impact of magnesium ions formed into nickel hydroxide electrode structure. Second part deals with battery charging/discharging and response measurement tool design. National Instruments hardware PXI modules for data acquisition was used and program in LabView environment was made. Last one is concerned with nickel-cadmium cell properties changes during increased temperature stressing. Investigation of cell self-charge changes during lithium hydroxide addition into electrolyte was made.

Audiovisual stimulator
Bartoš, Michal ; Čech, Petr (referee) ; Hrozek, Jan (advisor)
The main objective of this study is to learn about the audiovisual stimulator and to create hardware resolution of stimulation LED glasses and in environment of the program LabView application, which operate this stimulation LED glasses and in the same time create sound of stimulation. Use environment of the program LabView. Application, which is create in environment of the program LabView, enable operate stimulation LED glasses and arrange sound from three source with two different method, which use modern AVS. Application contains a lot of security, informative and agreement components.

Possibility of using LabView for simulation and calculation of the energy balance of a hydrogen-oxygen fuel cell
Fryda, Daniel ; Macháček, Jan (referee) ; Šlezingr, Jan (advisor)
This bachelor thesis deals with the calculation of the characteristics of hydrogen-oxygen fuel cell and their simulation in LabVIEW. It is divided into several parts. At the beginning thesis clarifies the issues of fuel cell and contributes to a better understanding of its activities. It explains what a fuel cell actually is, what is the principle of its work, describes its components, access to its history and its development to the present. Further on the thesis divides fuel cells into the different types and deals with deeper hydrogen-oxygen fuel cell. The fourth chapter is devoted to its use in practice and in laboratory education . Another part is focused on the LabVIEW program where is described the principle, use and basic parts of the program. In the practical part is implemented the model of the laboratory task in LabVIEW program. In chapter no. 6 are developed the operating instructions of the program and described in detail the creation of the model. The aim of this bachelor thesis is creation of an overview of fuel cells, their properties and possibilities of using for practice and laboratory education and then simulation of the laboratory task in LabVIEW program which is based on measured data and the characteristics of the hydrogen-oxygen fuel cell. This laboratory task can be used as teaching material for students in the Department of Electrical Power Engineering.

Machine tools safety
Smetana, Štěpán ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
This Master’s thesis concerns about the safety of machinery, in the literary research part you can find information about the law system and requirements of European Union and Czech Republic. There is a description of the legal enactments, which the manufacturers of machinery needs to follow. Second part of this thesis is about the safety of a milling center. The milling center is analyzed here, you can find here the description of its components. The milling center was then described with the help of block diagrams. For each component from the block diagram you can find here a list of dangerous situations which can occur and also a list of safety precautions for each situation. Based on these information the list of requirements for the milling center was made.

DSP56800 microprocessor line usage for asynchronous motor control
Kukuczka, Adam ; Huták, Petr (referee) ; Klíma, Bohumil (advisor)
Tato diplomová práce pojednává o možnostech simulace a modelování elektrických pohonů na základě Bondových grafů. Je zde uvedena základní teorie k problematice. V práci jsou představeny modely stejnosměrného a synchronního stroje sestavené touto technikou. Dále je zde seznámení s Freeware knihovnou Bondových grafů BG V2.1 k programu MATLABSimulink. Za pomocí této knihovny byly sestaveny oba modely strojů. V poslední kapitole je uvedeno srovnání modelování na základě teorie Bondových grafů s modelováním v blokových diagramech.

Creation of LabView application for automatic measurement of switchgear temperature rise
Kopunec, Vít ; Huzlík, Rostislav (referee) ; Valenta, Jiří (advisor)
The aim of this work is to create an automated measurement of the temperature increase of electrical devices using the graphical programming environment of LabVIEW. To measure the temperature increase, up to four thermocouples are used of any type. The final .vi file must meet the requirements for the particular option settings; before running a measurement. On the front panel .vi file, is displayed the following configuration elements: time measurement, number of measurements, thermocouple type and amplification. The programme measures the voltage of the thermocouples, recalculates the value of voltage to the temperature, measures the values to write to a file with a txt extension, and writes values into the tables, constructing useful graphical information of physical measurements.
