Evolutionary Analogue Amplifier Optimisation
Bielik, Marek ; Zachariášová, Marcela (referee) ; Bidlo, Michal (advisor)
Táto práca demonštruje možnosti využitia evolučných algoritmov, konkrétne evolučných stratégií, v doméne dizajnu analógových zosilňovačov. Do implementácie je zahrnutý ngSPICE simulátor, ktorý je použitý na vyhodnotenie optimalizovaných riešení a v práci je navrhnutých niekoľko vyhodnocovacích metód. Práca tiež zahŕňa experimenty a ich výsledky, ktoré boli použité na určenie najvodnejších parametrov evolučných stratégií. Cieľom bolo optimalizovať hodnoty súčiastok jedno a dvoj stupňových zosilňovačov s bipolárnymi tranzistormi v zapojení so spoločným emitorom. Výsledkom je nástroj umožňujúci návrh zosilňovačov s ľubovoľným zosilnením v rámci možností daného obvodu bez použitia akéhokoľvek matematického aparátu.

High data rate image processing using CUDA/OpenCL
Sedláček, Filip ; Klečka, Jan (referee) ; Honec, Peter (advisor)
The main objective of this research is to propose optimization of the defect detection algorithm in the production of nonwoven textile. The algorithm was developed by CAMEA spol. s.r.o. As a consequence of upgrading the current camera system to a more powerful one, it will be necessary to optimize the current algorithm and choose the hardware with the appropriate architecture on which the calculations will be performed. This work will describe a usefull programming techniques of CUDA software architecture and OpenCL framework in details. Using these tools, we proposed to implement a parallel equivalent of the current algorithm, describe various optimization methods, and we designed a GUI to test these methods.

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.

Evaluation and Improvement of the Internet Marketing Strategy of an Existing E-commerce Business
Marcely, Peter ; Goga, Martin (referee) ; Chlebovský, Vít (advisor)
Úspech spoločnosti venujúcej sa elektronickému predaju je hlboko prepojený s nástrojmi internetového marketingu. Široká škála týchto produktov je zložitá na zoptimalizovanie a nastavenie celého procesu tak, aby pracoval efektívne. Efektívnosť v tomto prípade značí pozitívny návrat investície, ktorú do nástrojov vkladáme. Orientácia na zákazníka je dôležitý faktor pre všetky e-business spoločnosti. Zákazníci vyžadujú veľké množstvo doručovacích a platobných možností ako aj rýchlu zákaznícku podporu cez chat alebo telefón. Táto diplomová práca ukazuje všetky tieto aspekty a zároveň demonštruje praktické možnosti použitia internetového marketingu ako aj vylepšenú zákaznícku podporu.

Algorithms for advance production planning and scheduling
Kršák, Pavol ; Kaczmarczyk, Václav (referee) ; Pásek, Jan (advisor)
Bachelor‘s thesis analyzes solution of operational problems of production planning. Pur- pose of the thesis is presentation of operational problems of production planning and following proposal and implementation of planning algorithms in language C# on specific planning problem. By the presentation of the problematic is listed company „COMPAS automatizace s.r.o.”, which enabled implementation of the project. The thesis analyzes planning methods and process of their implementation. More specifically the thesis ana- lyzes evolutionary algorithms, expert systems in planning and deterministic planning via linear programming. In third chapter is described in more details planning program of production of coffee blends, which was provided by COMPAS company. Like a next, the thesis describes specifically proposal of solving based on evolutionary principle. The solving consists of the model of technology designed to production of coffee blends and ActionList. ActionList represents a set of rules that are governed by model. Then ru- les are defined undergone an evolutionary process in an effort to find better solution the existing. Applied features implemented in the system COMES to repurpose by the imple- mentation of module COMES Modeller are developed together with detailed description in the fourth chapter.

Mobile Cryptocurrency Wallet Based on zk-SNARKs and Smart Contracts
Slávka, Samuel ; Perešíni, Martin (referee) ; Homoliak, Ivan (advisor)
Cieľom tejto diplomovej práce je navrhnúť a implementovať prostredie pre kryptomenové peňaženky, ktoré je optimalizované pre požiadavky na úložisko a prenosovú rýchlosť v mobilných zariadeniach. S využitím zero-knowledge dôkazov navrhujeme mechanizmy side-chain výpočtu, ktoré overujú reťazce hlavičiek blokov a uchovávajú dôkazy o ich overeniach v blockchaine. Ľahkí mobilní klienti, využívajúci toto prostredie, už nebudú nútení sťahovať a neustále aktualizovať svoj reťazec hlavičiek, ale môžu používať záchytné body uložené v Smart kontrakte. Táto práca taktiež zahŕňa implementácie mobilnej peňaženky, ktorá používa implementované prostredie pre synchronizáciu s viacerými blockchainami.
