Parallelization and Optimization of Image Processing Applications
Šiška, Jakub ; Seeman, Michal (referee) ; Černocký, Jan (advisor)
This Bachelor's Thesis was performed during a study stay at the École Supérieure d'Ingénieurs en Électronique et Électrotechnique Paris, France. It proposes solution for speeding up image processing algorithm and its adoption for use with real-time video stream from the infra red camera. The first part discusses characteristics and basic principles of the IR technology, followed by specifications of used camera. Ongoing text also proposes solution of problems concerning network communication with the camera. In addition, it describes camera's output stream format characteristics and solution for output visualisation. Substantial part of this work covers issues concerning parallelization and optimization of video stream and image file data processing. Problem of the parallelisation for this case is explained together with implemented parallelization method. Entire theoretical part is supported with the real results, benchmarks, which are presented in the last chapter.

Marketing-Product Strategy at Mediahost Company within The Home Market
Šiška, Jakub ; Fronko, Marcel (referee) ; Chlebovský, Vít (advisor)
Tato diplomová práce navrhuje marketingovou strategii pro firmu Mediahost podnikající v oboru hostingových služeb. Strategie je zaměřená na slovenský, tedy pro společnost domácí trh. Strategie je podložená příslušnou analýzou. V tomhle případe byl použit “seven Cs” model, taktéž znám jako Compass model, a to spolu se SWOT analýzou. Strategie navrhuje komplexní marketingovou strategii odrážející současné prostředí hostingového trhu.

Acoustical room impulse response database with parametrization of subsequent reverberation
Šiška, Jakub ; Schimmel, Jiří (referee) ; Balík, Miroslav (advisor)
Theoretical part of this bachelor’s thesis discusses description of impulse response, echogram, various methods of impulse response measurement and their comparison. Next part includes describing objective acoustical parameters, remaining energy analysis and its frequency dependent visualization by energy decay relief. Furthermore, existing databases of impulse responses are documented. The practical part consists of realization of own database of impulse responses and various graphical visualizations computed from these impulse responses. In the next part, algorithm for energy decay relief parameterization and modeling of impulse responses is described and realized in Matlab software. In the last part, a listening test is performed to verify impulse response modeling.

The Strategy Proposal of ESET Company
Kyseľová, Barbora ; Siska, Jakub (referee) ; Chalupský, Vladimír (advisor)
Diplomová práce navrhuje strategické řešení pro firmu ESET podnikající v oboru zabezpečovacího softwaru pro různé platformy. Ke kritickému prozkoumání trhu byly použity Porterův model pěti sil a také SWOT analýza. Taktéž použitá metoda benchmarkingu objasňuje trendy na tomto specifickém trhu. S ohledem na současní situaci na trhu jsou navrhnuty strategické řešení pro budoucí růst společnosti.

Restoration of audio signals damaged by quantization
Šiška, Jakub ; Rajmic, Pavel (referee) ; Záviška, Pavel (advisor)
This master’s thesis deals with the restoration of audio signals damaged by quantization. The theoretical part starts with a description of quantization and dequantization in general, few existing methods of dequantization of audio signals and theory of sparse representations of signals are also presented. The next part introduces algorithms suitable for dequantization, specifically Douglas–Rachford, Chambolle–Pock, SPADEQ and implementation of these algorithms in MATLAB application in the next chapter. In the last part of this thesis, testing of reconstructed signals using the algorithms takes place and results are evaluated by objective measures SDR, PEMO-Q, PEAQ and subjective listening test MUSHRA.
