Acceleration of Data Compression with Parallel Architectures
Juránek, Luboš ; Tříska, Vít (referee) ; Šimek, Václav (advisor)
This bachelor thesis deals with the use of parallel architectures, in particular the GPU, for acceleration of selected lossless compression algorithms, based on a statistical method, and transformations, which change the entropy of the input data to achieve better compression ratio. In this work there are in theory summarized general information about parallel architectures and programming options for them, mainly using NVIDIA CUDA and OpenCL.

Theremin: Touchless Musical Instrument
Baštýř, Lukáš ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
This bachelor thesis deals with the design and implementation of a digital touchless musical instrument theremin. In the first part, the theremin, its features and existing solutions are first documented. The second part focuses on the documentation and testing of the software and hardware that can be used to solve this thesis. The penultimate part focuses on the actual implementation of the instrument and the creation of a working prototype. The final section tests functionality of the final prototype instrument.

Design and Analysis of Systems for Advanced Guarding and Securing Objects and Areas
Komínek, Petr ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
This diploma thesis deals with design, realization and analysis of security and surveillance systems for buildings and spaces containing advanced components. One of the main design's parts is dedicated to intruder alarm system, access system, attendance and CCTV systems with the possibility of automatic motion tracking. Controlling and monitoring of particular subsystems is possible both locally and remotely from a computer via a web interface or by means of a software. The access to camera system from a mobile phone is also possible. IAS/ACS systems also enable controlling and transferring information about their state via SMS. The designed system was realized completely and its operating was demonstrated. The realization is described in detail including illustration of configuration of particular components. A security analysis and a possible future development of the project is summarized in the conclusion.

Embedded System for Water Level Monitoring
Hanák, Jiří ; Kašpárek, Tomáš (referee) ; Šimek, Václav (advisor)
This work is dealing with the design and implementation of an embedded water level monitoring system. The purpose of the system is to control the filling of a tank based on the water level. First of all, the attention is given to the survey of existing measurement techniques and selection of the appropriate sensing elements for a given scenario. In fact, the embedded system is using TFmini and JSN-SR04T-2.0 contactless sensors. The system is controlled by STM32F0 microcontroller from STMicroelectronics programmed in C using HAL abstraction layer. The measured results are sent via Wi-Fi SoC ESP8266EX to the Python server that is used for processing and demonstratiton purposes.

HAM Station Log Book for Linux
Kaluža, Jan ; Růžička, Richard (referee) ; Šimek, Václav (advisor)
The goal of this bachelor's thesis is to design and implement an amateur radio logbook software for a GNU/Linux operating system. After the short introduction there are described existent logbook applications together with analysis of their advantages and disadvantages. Based on this analysis the logbook application is designed and implemented. Finally, there is a summary and discussion of possibilities for further improvements.

USB HID Monitor
Budai, Ondřej ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
The goal of this thesis is to design and implement application for in-depth analysis of USB HID devices’ structure and communication. The resulting application is capable of visualization various information retrieved from device. It can handle bidirectional communication between computer and HID device and it’s available for operating systems Windows and GNU/Linux under libre software license. Application with this set of features currently does not exist. Thus, its creation is really beneficial for all USB HID developers.

System for Recording and Reporting Fault States of Cooling Devices
Jašek, Filip ; Vašíček, Zdeněk (referee) ; Šimek, Václav (advisor)
The thesis deals with the design and creation of a system for recording and reporting error states of cooling devices on the principle of a compressor heat pump. An important element of the concept of the entire monitoring system is a built-in platform based on the ESP32 microcontroller for evaluating data measured by sensors. Another key element is the communication module, which sends measured data via GPRS in the form of MQTT messages to the service web application. The application receives, evaluates and records measured data. Subsequently are measured data and evaluated error states presented to the user in the form of tables and interactive graphs.

Acceleration of Data Compression Algorithms on Sony PS3 Platform
Breitenbacher, Dominik ; Jaroš, Jiří (referee) ; Šimek, Václav (advisor)
This paper presents the use of PlayStation 3 device for accelerating compression algorithms and tries to show the potencial of PlayStation 3 for use on these tasks. For a demonstration was selected compression method based on the Burrows-Wheeler transformation. The output of the transformation is further transformed by using the Move-To-Front transformation and subsequently encoded by the static Huffman encoding. The compression algorithm has been called PS3BWT. It performs compression by using each of tasks and tries to always use the maximum number of avaible processor units, so the compression is carried out as quickly as possible.
