Moving object detection
Škuta, Pavel ; Petyovský, Petr (referee) ; Richter, Miloslav (advisor)
The aim of this these was devise a automatic system applications, monitoring entering of motors vechitles with in automaric collection of trafic data. Automatic system allows identify of mooving vechitlses in slow speed and searching of the area registration number. Theoretical analysis of possible kind solving problems detection moving vechitles and their localization. From possible solutions was selected solution by camera systems. Was take a pictures of vechitles, whitch is as true of the real scene. On the pictures was testing of algorithm for detecting of area registraction number of vechitles. Designed system is possible to use for automatic monitoring mooving entering vechitles.

Grab Dredger
Kubánek, Jan ; Smutek, Josef (referee) ; Škopán, Miroslav (advisor)
When soluting the contruction of a grab dredger we will deal with suitable solution with reference to its using and capacity, possibilites of its setting in low temperatures and incidental aplication of the exchangeable abrasion - resistant mouldings. There will be made a calculation of forces taking effect on a grab dredger and a check calculation of the chosen structural parts.

Universal Graphic Editor Library and Python Module
Košulič, Jaroslav ; Kočí, Radek (referee) ; Smrčka, Aleš (advisor)
The diagrams, schemes, and graphs in general are widely used in the field of easy-to-read information visualisation. We use them for example in the school lessons for an algorithm presentation, or in the technical jobs such as software and hardware development by modelling UML diagrams, database schemes, etc. The project Universal Graph Editor has been established two years ago to fill the gap with the software tool providing such a modelling engine. The previous work has been reasumed in semestral project by design of the dynamic graph drawing (or the drawing of a vector graphic in general) and the library for graph manipulation with C-language interface. This master thesis continues further by creating a Python module using the developed interface. The documentation and the testing phase is conluding the annual work.

Data transmission in mobile networks
Bílek, Petr ; Molnár, Karol (referee) ; Havelka, Dušan (advisor)
The Bachelor’s thesis deals with mapping and usage of mobile networks of data transfers. It describes every particular generation of networks and technologies that they can use. This thesis is divided into two main parts, theological and practical. In the first part, the technologies of the second and third generation currently used for data transfer in mobile networks are described there. This concerns especially GPRS, EDGE and UMTS services. The thesis focuses on modulations used for these technologies, together with the coding and bit rates possible. It compares their advantages and disadvantages and presents their utilization among national operators. It also tries to sketch out the way the data services of mobile networks will proceed. The second part of the thesis is also divided into two parts. The first one is the simulation of the UMTS network with the assistance of the OPNET Modeller 14.5 environment. In this case, the thesis aims at two important characteristics - such as the dependence on the bit rate and distance of the primary station, and dependence on the bit rate and total load of the whole network. Both characteristics are observed mainly because of the bit rate and power characteristics. It describes objects and funcions of the OPNET environment. The next part in the practical section is the factual measurement of the Internet 4G service, provided by T-Mobile operator. The thesis focuses here on the presentation of the outcomes which were accomplished by the practical measurement of that service. The end of this thesis is dedicated to the comparasion of simulated outcomes with the outcomes practically measured, and to the conclusion of the results emerged from them.

Quality and accessability measurement of GSM network
Vondra, Marek ; Wieser,, Vladimír (referee) ; Hanus, Stanislav (advisor)
The thesis is specialized on a possibility of measuring qualities and availability of a cellular radio system and also on evaluation qualities, fruitfulness interface, permeability etc. It includes short description of a basic mobile technology. Further analysis of the possibility of measuring the mobile network and how implement the measure. It also includes a draft program for measuring and evaluation of the GSM network with help several tests by a mobile phone connected through the Bluetooth.

Methods for Segmented Image Processing
Štěrba, Radek ; Číka, Petr (referee) ; Zukal, Martin (advisor)
This work deals with the representation of segmented images using graphs. Different segmentation methods used in processing visual information are described here. Today is mathematics increasingly needed. This fact is not omitted, basic information of graph theory are described in this paper. The second part of this work is practical. It contains a survey of libraries processing graphs. Further the data structures for describing the segmented image are described. Last but not least, there is also described the formation and properties of the operators designed for environment RapidMiner that fill these structures.

Data transmission in GPRS and EDGE networks
Slovák, Jiří ; Ries, Michal (referee) ; Hanus, Stanislav (advisor)
The thesis is conceived as a part of the laboratory task innovation in subject Radio and mobile communications. The main part of the project is to create a complex GUI application in MATLAB programming environment that mediates measuring of bitrate in GPRS and EDGE networks, communication with used modem via virtual serial port and consists of other related functions. The problematics is at first described in detail on theoretical basis with special focus on physical layer of mobile technologies mentioned above. In practical part, there are briefly outlined mechanisms that were used during development. The following part consists of a detailed description of the application itself, created using gained theoretical knowledge.

Polygonal Models Smoothing
Nečas, Ondřej ; Herout, Adam (referee) ; Kršek, Přemysl (advisor)
The result of digitalization 3d surface is affected by many factors. After digitalization can on the surface emerge some unwanted artefacts. The differences from original are caused by resolution of the device or its limited precision. For elimination of this artefact exists many smoothing algorithms, but we want to choose that which best suits this purpose. So it is useful to know their limits and characteristics.
