VBS macros for TIA portal V12 applicable to panels COMFORT respectively RT
Benešl, Tomáš ; Arm, Jakub (referee) ; Pásek, Jan (advisor)
The aim is to create a VBS macros for working with databases, which will be managed phonebook and SMS messages and using a GSM module to send and receive messages. Create scripts for operations with alarms - seting and automatically sending. VBS macros for working with data CSV files and also create a way to control the barcode reader. Create a test application with the macros and test it in practice.

Voice Activity Detection
Břenek, Roman ; Grézl, František (referee) ; Matějka, Pavel (advisor)
This thesis describes techniques for voice activity detection in audio recordings. It is necessary to correctly classify all non-speech segments and recognize speech with noisy background. The whole process of voice activity detection (VAD) is described in this thesis, i.e. digitizing audio signal, feature extraction, training of the system, post-processing and final evaluation. There are three different systems compared within the thesis . The first one is based on phoneme recognition using neural network, the other two are variations of Gaussian Mixture Models (GMM). Each system was tested on three data sets - Tactical Speaker Identification Speech Corpus (TSID), Ham Radio (HR) and Rich Transcription Evaluation (RT05-RT07). The best results of each system are compared with the results of the third side.

Sample projects for operator panels
Urbánek, Matouš ; Šír, Michal (referee) ; Zezulka, František (advisor)
In this bachelor’s thesis will learn about the development of exemplary projects that are designed with fixed functionality for operator panels SIEMENS (BASIC, COMFORT, RT). For this task, I have a development environment TIA portal that brings together many software tools and programs. With which allowed me to create code for specific hardware, and communication with him, or in simulation mode to test the behavior of the application in a real environment. Code, on the PLC is required for the platform (PLC) S7-1200. It is modern and provides flexibility in making out our needs in automatik. The task is engaged, firstly synchronization solution PLC and HMI operator panel. Secondly resipes in these panels.

Media image of the crimean crisis on Russia Today, CNN and ČT24 news
Štěpán, Petr ; Lokšík, Martin (advisor) ; Nečas, Vlastimil (referee)
This thesis analyses how three television stations - Czech ČT24, Russian RT and American CNN - informed about the Crimean crisis which took place in Ukraine in 2014. The first part of the thesis presents theoretical approach and mentions previous similar studies, which focused on examining of medial coverage and framing of war conflicts. Next chapter describes the history of Ukraine briefly and underlines events which could have caused the Crimean crisis. Thereafter the thesis introduces the timeline of the Crimean crisis. In the next part the thesis analyses sources, topics and keywords which appeared in the news of ČT24, RT and CNN. It also describes how particular people and events were visually covered. In the final chapter the approach of the three examined television channels is compared.
