Optimization of Run Configurations of k-Wave Jobs
Sasák, Tomáš ; Jaroš, Marta (referee) ; Jaroš, Jiří (advisor)
This thesis focuses on scheduling, i.e. correct approximation of configurations used to run k-Wave simulations on supercomputers from the IT4Innovations infrastructure. Especially, for clusters Salomon and Anselm. A single work is composed of a set which contains many simulations. Every simulation is executed by some code from the k-Wave toolbox. To calculate the simulation, it is necesarry to select a suitable configuration, which means the amount of supercomputer resources (number of nodes, i.e. cores), and the duration of the rental. Creation of an ideal configuration is complicated and is even harder for an inexperienced user. The approximation is made based on the empiric data, obtained from multiple executions of different sets of simulations on given clusters. This data is stored and used by a set of approximators, which performs the actual approximation by methods of interpolation and regression. The text describes the implementation of the final scheduler. By experimenting, the most efficient methods for this problem has found out to be Akima spline, PCHIP interpolation and cubic spline. The main contribution of this work is creation of a tool which can find suitable configuration for k-Wave simulation without knowing the code or having lots of experience with its usage.

Optimization of single-page application startup
Bartoň, Jan ; Švikruha, Patrik (referee) ; Ilgner, Petr (advisor)
This thesis concerns with optimalisation of launching the single page JavaScript application Kentico Kontent. It especially focuses on dividing JavaScript libraries and packages into independent files according to certain criteria. These adjustments to the application are divided into several scenarios. For every scenario, six types of measurements have been carried out, due to which the impact of the change on the speed of loading the application and the amount of transferred data from server to client was found. The result of this thesis is a proposal of adjustments which lead to a faster launch of the application, due to a smaller amount of data being transferred from the server, therefore the application can use the browser cache more effectively.

Coordination of operation of PST transformers in the interconnected region
Tesař, Jan ; Topolánek, David (referee) ; Bátora, Branislav (advisor)
This master’s thesis deals with phase-shifting transformers (PST) and coordination of electrically close devices in an interconnected region. Theoretical research is performed in the work, describing methods of power control, function and design of PST, as well as actual methods of PST coordination in the rest of the world. Based on the research there is an optimalisation algorithm designed in MATLAB, which computes recommended tap petting of PST based on the network configuration. In the second part of this thesis there are described components of this algorithm and also presented the results of three demonstrative scenarios. Algorithm is able to solve minor problems in the network; more complex problems are beyond its solving ability. For an improved functionality there is a necessity to further expand this algorithm by a network redispatch solving algorithm.

The Study of Economics of Tooling Technology
Ondrášek, Dušan ; Humár, Anton (referee) ; Jurová, Marie (advisor)
The aim of this diploma thesis addresses issues related to obtaining methodology for the production manager´s decision-making process in the field of technology selection, suitable tooling and cutting tools selection for a specific order or particular production plan. Evaluation of the manufacturing process while taking into consideration complexion of process controlling and contexture to the economy of this process. Analysis and evaluation of technological and economical aspects of a manufacturing process of the CNC chip machining in a real environment is targeted on the field of tooling, its selection, purchase, economy and consumption. The process controlling of technology is based on this analysis as well as the formulation of measuring by economic indicators such as economy, productivity, profitability etc. The analysis of important factors and parameters of this process demonstrated an influence on economy of the company. Several model cases have been created from the company records and from the provided research, the output of which became a basic methodology. The output of the analysis indicates possible directions of a management decision making. Thanks to a complex technical-economic view this thesis can serve as a methodological instrument for decision makers in the field of technology and cutting tool selections as well as an economy of production process improvement.

Power supply optimalization of FSI, Technicka 2
Fortelný, Zdeněk ; Borbély, Richard (referee) ; Pospíšil, Jiří (advisor)
The subject of this diploma thesis is the optimalization of energetic supply of FME- Technická 2, Brno. The supply optimalization is thematically connected to Ing. Jan Kučera´s diploma thesis. The project is divided into several parts. One part is focused on general clarification of the term cogeneration and possible pertinent technologies. The contemporary state and energetic needs of area are analyzed in the second practical part of the thesis. Remaining chapters are focused on comparison and economical analysis of the proposed modules. The conclusion is devoted to the overall effect of selected modules on energetic consumption in the object.

SHORTING DEVICE DRIVE OPTIMALIZATION
Michalík, Marek ; ABB, Drahomír Tůma, (referee) ; Dohnal, Petr (advisor)
Tato bakalářská práce se zabývá optimalizací pohonu zkratovače ve vysokonapěťovém rozváděči ve spolupráci s firmou ABB s.r.o, pro kterou je tato práce zpracovávána. V první části se zabývá teoretickým rozborem spínacích přístrojů se zaměřením na bezobloukové spínací přístroje, kam patří i zmiňovaný zkratovač. V dalším textu jsou aktuální informace o teorii elektrických pohonů, které jsou později využité v praktické části. Podrobněji se práce zabývá teorií stejnosměrných strojů zejména motorů s permanentními magnety, jelikož tento druh motoru je použit i v pohonu, který pohání použitý zkratovač. V další části je rozebrán celý pohon a všechny jeho části, několik odstravců je věnováno i výběru druhu optimalizace a zhodnocení současného stavu pohonu se zaměřením na jeho chyby a nedostatky. Jsou popsány parametry současného motoru a převodovek. V praktické části se dá nalézt protokol o zkoušce zkratovače, která proběhla v ABB s.r.o. V poslední části je k dispozici protokol z měření současného stavu nezatíženého pohonu. Jsou podrobně rozebrány a porovnány možnosti optimalizace pohonu. Všechna nabízená řešení byla důkladně konzultována se zástupci a techniky z průmyslových firem.

Virtualisation and Optimalisation of IT in a Production Company
Popelka, David ; Hégr, Robert (referee) ; Ondrák, Viktor (advisor)
The master‘s thesis deals with the implementation of server virtualization in the Entity production, s.r.o., which is a small company by it’s size, but needs modern IT technologies for the normal operations. The thesis shows how to reuse the server virtualization technologies from large corporations, that have been unavailable to small business companies in past. It also design show to optimize the current IT environment.

International Tax Planning and its Impact on Company's Economy
Vlk, Tomáš ; Koutný, Jiří (referee) ; Kopřiva, Jan (advisor)
Aim of my master’s thesis on the topic „International Tax Planning and its Impact on Company's Economy“ is to evaluate current business model of the firm Jelko which is using it for products selling to the Slovakia. Based on the currect model analysis I will introduce other models, which could cause higher efficiency of advantageousness. I will analyse advantages and disadvantages of each model and following this analysis I will choose the best model which I will recommend to the firm in order to consider it and eventually to implement it.
