Basic measurement of bipolar and unipolar transistor
Kaňa, Leoš ; Šebesta, Jiří (referee) ; Dřínovský, Jiří (advisor)
In terms of the better effectiveness in the sphere of transistor characteristics measuring, no matter unipolar (FET) or bipolar (BJT), in laboratory conditions and their better understanding in terms of thrash out a subject matter is desirable have to available workplace let us say preparation enabling this kind of measuring with modifiability wiring and with possibility to change measured component. This thesis isn‘t focused only on development of this kind of universal component for measuring but simultaneously contains brief summary about the theory and parameters of transistors. Next aim is the development and realisation of static characteristic measuring program in VEE 8.0 Pro environment. Finally the complex laboratory exercise has to be done for measuring of bipolar and unipolar transistor’s static characteristics include programs for automatic measuring. For developing of DPS was used developing system named Eagle which gives us instrument with sufficiently accuracy. In thesis is contained theory needed for measuring and programming. Except possibility of measured component change we can change transistor connection in circuit on the board. This change is available for BJT (CE, CB, CC) and unipolar JFET (CS, CG, CD) transistor’s.

Automatic control of the gate
Harman, Ján ; Šebesta, Jiří (referee) ; Frýza, Tomáš (advisor)
The aim of my bachelor’s thesis is a automatic control of the ventilation gate. It is electronic equipment which opens and closes gate depending on input signal. The gate is driven by electromotor. Thi equipment can serve as stand alone or as a component in the bigger system controlled by computer.

Arithmetic Circuit Generator
Bolješik, Michal ; Mrázek, Vojtěch (referee) ; Vašíček, Zdeněk (advisor)
The goal of this thesis is to design and implement a tool that would be able to generate a description of various types of arithmetic circuits, such as adders and multipliers, that are involved in more complex systems (filters, transformations, etc.). The first part of the thesis deals with analysis of different types of adders and multipliers on either theoretical or practical level. In the second part there is a description of the design and implementation of the tool created in Python language. On base of parameters, the tool is able to generate hierarchical or flattened description of various circuits in formats aimed for visualization, simulation and validation. In the end, the tool is used to compare different designs of adders and multipliers.

Autonomous Management of Intelligent Home
Punčochářová, Pavlína ; Viktorin, Jan (referee) ; Korček, Pavol (advisor)
Currently, the topic of smart home is not new and there are many solutions for this problem on a market. Emphasis is placed on miniaturization of the individual elements of an intelligent system and control logic of the system as a whole. This is associated with requirement for ensuring management capabilities of the system in case of failure of the connection between some of the functional elements and the control member. This work deals with design and implementation of modifications in intelligent home gateway in an existing BeeeOn project to ensure its autonomy even in case of loss of internet connection. The problem of loss of ability to manage the household is solved by adding the possibility to establish direct communication with the gateway and the introduce automation ability into gates to control household without the participation of the controlling member. This extension brings autonomy into the system and allows user to have the household under control even in case of loss of internet connection. It leads to increase system security and quality of service in general.

The Alchemy like the Gate to Luck
Erös, Roman ; Čechura, Jaroslav (advisor) ; Zdichynec, Jan (referee)
Synopsis The aim of this Bachelor thesis is not rendered and reveal the alchymist procedures, but rather to know the thinking of the alchemists and their destinies, because not all of them were con artists who would like to share the fraudulent ways and so enrich at the expense of its surroundings. A few of them not only made money, but even borrowed, and eventually ended up in prison. Most of them really believe in their dreams of actinide transmutation and extending the life and the other on the contrary, have ceased to believe in the miracle of riches by using the transmutation and rather started to think about whether something like that is possible and then go back to the top. And it was actually the beginning of the inquiry and that of the beginning of a new scientific discipline and chemistry. Of course, that together with the effort of the alchemists of actinide transmutation of metals, and search for the stone is associated and the destinies of famous players of this science and it, from the founder of the Herma Trismegistose to the present, because the dream of the alchemists is not foreign or today's man.

Analysis of Trench Insulated Gate Bipolar Transistors
Karlovský, Juraj ; Polčák, Josef (referee) ; Bábor, Petr (advisor)
This thesis is focused on the selection and optimalization of suitable analytical methods for study of TIGBT (Trench Insulated Gate Bipolar Transistor) structures with a use of methods, that depict material composition of the studied sample. The theoretical part contain explana-tions of the analytical methods used for measurements and basic principle of operation of an TIGBT transistor. The practical part contain the methodic of measurements and the evaluation of the obtained data and design of optimal procedures in done experiments.
