Dimensional analysis for HD languages
Horváth, Martin ; Jirovský, Václav (referee) ; Bednárek, David (advisor)
The engineers today use special description languages for developing electronic circuits and these enable them to test their models prior to their industrial construction. However, none of these languages provides sufficiently complex means to define physical dimensions and units for quantities used in the models and to check their consistency in all equations and computations. The inconsistency in the usage of physical units can be caused by plain typing errors but sometimes represents deep conceptual flaws. The tracking of these errors can be very difficult as the models commonly consist of thousands of lines of code. This master's thesis sets itself two goals. The first is to analyze the problem of physical dimensions, formalize their properties and devise an algorithm for automatic checking of their usage in the models written in hardware description languages. The second is to design and implement the system for annotating models with dimensional information and to implement the algorithm of dimensional analysis as a module into commercial tool ModLyng which is the integrated environment for developing analog/mixed-signal integrated circuits. The usage of this automatic analysis will help engineers in writing correct models and will speed up their development.

Utilization of biomass energy
Horváth, Martin ; Bok, Jaromír (referee) ; Procházka, Zdeněk (advisor)
Restoring sources of a energy and their development brings questions how these can be these sources the best utilized. The main aim of my bachelor`s thesis is an acquainted with methods of biomass conversion to energetic potential and his advantage. Than is mentioned proper project of the biogas plant and calculation of produced electric energy quantity in select cogeneration unit base on data on specific excrements production bred pigs and biogas production from slurry. The result is a variant evaluation of economy of the biogas plant operation for agricultural enterprise according to number of bred pigs and possibility of electric energy utilization.

Grit-off photovoltaic system
Horváth, Martin ; Dolenský, Jan (referee) ; Vaněk, Jiří (advisor)
The restoring sources of energy and their development brings the question how these sources can be utilized in the best way. Master`s thesis deals with photovoltaic systems. It describes their history line, actual situation and also brings some expectations in the future. There are mentioned some materials and technologies which are used for its manufacture, conditions of using in practice, advantages and disadvantages and finally a real mobile application of photovoltaic which serves for a production of electricity that is saved in the battery.
