Activities of the SKPOS National Service Center
Ferianc, Martin ; Smolík, Karol
The National Service Center of the Slovak Real-time Positioning Service (SKPOS NSC) does not perform only operation of the national positioning service, management of the service users and handling of the control software. It ensures many other interesting activities, such as detailed testing of the real-time service, checking the data quality of the SKPOS reference stations, processing the SKPOS network using Bernese software, analyzing the geokinematics of Slovakia, modernization of the network by searching for suitable potential locations for new reference stations or building the so-called National Reflector Network connecting GNSS and InSAR technologies. To work with data SKPOS NSC uses commercial software, as well as its own developed applications and scripts. It also operates a website and a Facebook funpage. In addition, NSC SKPOS is an EPN operation center, which manages reference stations in Slovakia included in the permanent EUREF network (EPN), contributes with daily or weekly network coordinate solutions to the EPN Densification project. Within the E-GVAP and HUSKROUA projects, it contributes with hourly near-real-time station data to the weather forecast predictions. Besides that, it performs quality control of selected international real-time networks within the European Position Determination System (EUPOS) initiative. The post describes individual activities in detail.

Creation and processing of signal database
Glett, Jiří ; Šebesta, Vladimír (referee) ; Sigmund, Milan (advisor)
The work become acquainted with history and rise databases globally. Construes philosophy structuralization, sorting and purpose using. Work further deal with concrete databases softwares intended directly to processing audio signals. Further treat of programmes that the make possible generation personal database structures. Work deal about SUSAS database and analysing its content. It is created self database of music signals, which includes several musical groups always similar in certain aspect. Speech database contains records from the SUSAS database and records from television programs, reality-shows, sports broadcasts, reports and documents, when speakers are subjected to stress and emotions. The work is a database program that can effectively classify all records and processes. The database can be freely extended. The resulting program was realized into Czech and English version.

Electronic Circuits for Biomedical Applications
Pisarenko, Tatiana ; Langerová, Petra (referee) ; Zmrzlá, Petra (advisor)
Tato bakalářská práce obsahuje úvod do biomedicínských signálů a možnosti zpracování těchto signálů elektronickými obvody. Významná část práce se zaměřuje především na popis EMG signálu. Součástí práce jsou take schemata elektrických obvodů, které se používají především pro zpracování EMG signálů. Dále má práce praktickou část, v níž byly v simulátoru OrCAD Capture ověřovány funkce a parametry navrženého obvodu.

Design of a Solution for Effective Analysis of Security Data
Podlesný, Šimon ; Gardian, Ján (referee) ; Luhan, Jan (advisor)
The goal of this thesis is to design architecture capable of processing big data with focus on data leaks. For this purpose multiple data storage systems were described a and compared. The proposed architecture can load, process, store and access data for analytic purposes while taking into account authentication and authorisation of users and principles of modern agile infrastructure.

Training system for clibmers
Polach, Pavel ; Sekora, Jiří (referee) ; Bubník, Karel (advisor)
The purpose of this diploma thesis was design and realisation of measuring system, enabling measuring forces between climber´s feet and holds on the climbing wall and using this measu-red values during a training of sport climber. In this thesis there are discovered possibilities about constructing this system and determina-ted basic requirements of measuring. There are also stated principles of application the strain gauges for measuring the tension. Descriptions of developping specific sensors, hardware interface and PC application are also part of this thesis. Constructed system was used for mea-suring climbers and values were analysed by using the application.

Device for scanning the museum collection
Drapač, Lukáš ; Janáková, Ilona (referee) ; Honec, Peter (advisor)
This bachelor thesis deals with designing and construction of the device, which should improve the digitalization of the museum collection of Easter eggs in terms of effectiveness and data presentation. This thesis presents design of the device, which was printed on a 3D printer, and the hardware components of the device. Programs for controlling the device and rendering 3D models of Easter eggs were written in C++, C# and Java. When started, the device takes pictures around the perimeter of the Easter egg and processes them. The results are 3D models, which can be viewed from Gallery in the desktop application.

Implementation of voice activity detectors using open-source libraries in C language
Mach, Václav ; Špiřík, Jan (referee) ; Míča, Ivan (advisor)
This diploma thesis discusses the issue of Voice Activity Detection. There are two types of detectors described: energetic and statistics. Their funktionality is proved in the Matlab environment. Further, the implemetation of VADs is made through C language with standard libraries and GSL open-source libraries. The realized algorithms are compared in the scope of processing time of computation, memory management and a single mathematical operations stress. Also a comparism of the processing time according to segment length was made.

Methods of multiple access for terrestrial radio networks
Žák, Josef ; Novotný, Vít (referee) ; Havelka, Dušan (advisor)
The content of this work is focused on the methods of multiple access for terrestrial radio network. These methods are exploited by the systems second and third generation of mobile networks. Specification the basic characteristics these methods is responsible part for inquest the correspondent specificities. Reason is that, that the wireless mobile communication it is possible split by three generation. First is NMT, with analog frequency modulation, which dont make use already, because has considerable disavantages . Analysis second generation mobile systems GSM leads to determination to many advanta- ges hereof system, who be based on methods FDMA, TDMA, CDMA. Description these methods is specialized on their spreading properties. Third generation of mobile systems UMTS is characterized wideband technology WCDMA, making use two duplex methods (FDD, TDD). Both methods provide higher efficiency of recovery frequency spectrum . All the theoretical approaches are examined in the last part of this work.it´s then possible after complete analysis these methods, make a design and a realization. In this event was used the computer programme Matlab–Simulink for simula- tion of duplex method WCDMA-FDD. Evaluation of this technology provides confrontation with second generation GSM .

Monitoring equipment of degradation processes for material of animal origin
Chmelař, Vít ; Skácel, Josef (referee) ; Adámek, Martin (advisor)
The diploma thesis introduces the reader to the problems of chemical sensors and the basics of degradation processes in materials of animal origin. It describes some types of sensors and their principles. Atmel ATmega328 microprocessor, its parameters and programming are described. In the next part of the thesis there is a proposal and production of equipment for monitoring of degradation processes in materials of animal origin. Sample sof chicken and milk were mesuared. From these measurements, the gas concentration values were determined, where samples can be considered suitable for consumation.
