Design of unit for Power HIL simulation of DC motor
Chalupa, Jan ; Maršík, Jiří (referee) ; Grepl, Robert (advisor)
This thesis deals with analysis and implementation of Power-HIL system that is designed to simulate real DC motor with comutator and permanent magnets. For problem analysis were used simulations of real components in Matlab / Simulink. The electronic parts of system were simulated with using the SimElectronic library. Idividual hardware components were designed according to simulation results. The outcome of this thesis is a power electronic simulator of real DC motor, which is implemented on dSPACE platform. The system allows software to setup parameters and behavior of simulated motor. The final system can be used for testing DC motor ECU (electronic control units).

Rychlý a trénovatelný tokenizér pro přirozené jazyky
Maršík, Jiří ; Bojar, Ondřej (advisor) ; Spousta, Miroslav (referee)
In this thesis, we present a data-driven system for disambiguating token and sentence boundaries. The implemented system is highly configurable and versatile to the point its tokenization abilities allow to segment unbroken Chinese text. The tokenizer relies on maximum entropy classifiers and requires a sample of tokenized and segmented text as training data. The program is accompanied by a tool for reporting the performance of the tokenization which helps to rapidly develop and tune the tokenization process. The system was built with multi-platform libraries only and with emphasis on speed and correctness. After a necessary survey of other tools for text tokenization and segmentation and a short introduction to maximum entropy modelling, a large part of the thesis focuses on the particular implementation we developed and its evaluation.
