Software support of education in cryptography area based on elliptic curves
Szturc, Jakub ; Sobotka, Jiří (referee) ; Burda, Karel (advisor)
The master‘s thesis is focusing on cryptography based on elliptical curves consists of four main parts. The first part provides an overview of the basic cryptographic and mathematical concepts. A key element of this work is the second part which are described in detail the mechanisms of counting two points on elliptic curve and counting point to themselves over the various fields. On this mechanism is based almost the entire issue. In the third section provides the best-known algorithms and protocols for key exchange, encryption and digital signature. The goal of this paper is to devise software to support teaching. This material is created as a web presentation, which described the theoretical foundations and the main characteristics of cryptosystems based on elliptical curves. The whole issue is supported by practical examples of calculations examples, there are also examples for independent work. Additionally, java applets are prepared that allow an interactive opportunity to try the basic parameters of curves, or verify the calculations.

Revitalization of Film studios in Zlín
Myšková, Hana ; Kabela, Miloš (referee) ; Sátora, Josef (advisor)
This final diploma thesis deals with revitalization of Film studios in Zlín and its surroundings. On the west from solved area is forest cemetery and residential complex Fabiánka. Areal of the Film studios is from residential complex Fabiánka separated by terrain depression. The Film studios in Kudlov which is situated near to Zlín was established in thirties of last centrury, their strong side is interesting history, the natural environment and good availability from Zlin. The theme of the Film survived in the area to the present days, there are film laboratories and film secondary school. Some objects are rentes as office space, there is Zlín radio and on the northeastern part of the area is situated pharmaceutical production. The main new function witch is design is housing in apartment buildings which are completed by offices and public services witch is situated around film pedestrian zone. There is designed a new sports complex and film park with forest amphitheater, therefore it can be used by general public. In areal are functions for all age category.

Deinterlacing in uncompressed digital video sequences
Meňhart, Pavel ; Kratochvíl, Tomáš (referee) ; Slanina, Martin (advisor)
Interlacing is the process of frame scanning and frame displaying being based on the even and uneven lines‘ interchanging. This framework originated along with the PAL and NTSC television standards‘ formation in the course of 1930s. The process mentioned above stopped frames displayed on older TV sets from flashing. Nevertheless, there is a disadvantage of the frame processed after this manner, consisting in its attribute to be displayed in a clean-cut way just on classical TV sets. However, plasma and LCD television appliances, projectors and computer monitors always display the entire frame all at once, therefore composing it of the both fields, yet not being acquired concurrently, differing in moving objects‘ positions, moreover their contours are doubled, frayed and unfocussed. This master´s thesis deals with fundamentals of the interlaced video signal‘s formation, problems coming about at featuring the interlaced video like this, followed by operating methods of deinterlacing itself. In conclusion, there are my own softwares presented, having been developed in MATLAB computer environment and software command language C, and implementing some of the operating methods designed for deinterlacing in uncompressed digital video sequences.

Alias Analysis in C Compiler
Bolvanský, Dávid ; Zachariášová, Marcela (referee) ; Hruška, Tomáš (advisor)
This thesis is dedicated to the problem of alias analysis and possibilities of its improvement in the LLVM framework. The goal of this thesis is to improve the accuracy, which was achieved by extending the existing implementation of Andresen algorithm to be field sensitive. The terms related to alias analysis and algorithms of the alias analysis available in LLVM are explained. These algorithms are compared according to their base idea, features, and limitations. The implementation of the field sensitivity has been tested using compiler test suites. Its impact on program compilation speed and performance has been analyzed. The measured results show an increase in the accuracy of alias analysis in the LLVM framework.

Universal BLDC motor controller
Pijáček, Ondřej ; Pohl, Lukáš (referee) ; Veselý, Libor (advisor)
This thesis describes the design of universal control unit for BLDC motor powered from airplane power distribution system of 28 V capable of driving motor up to 10 A. The maximal engine power is about 250 W. Important prerequisite is possibility of driving various motor size without needs of changing wiring board using only the configuration in the auxiliary memory unit. To control different motors is enough one unit with one program without any way to interfere to the unit itself.

Sport Centre Brno
Shmykov, Egor ; Vostrejž, Dušan (referee) ; Odvárka, Antonín (advisor)
This paper deals with the sport complex of Brno. This sport complex consist of buildings which are called to increase of sport popularity in the city. One of the largest objekt of them is footbal stadium. Footbal stadium is devided into three main parts of building: spectators area, administrative todether with commentators area, and footbal players area. There is secured parking on -1 level for employees, players and VIP spectators. Of course there are necessary medical, secure and sanitary placements. With the architectural part of view footbal stadium add a reqired part of masterplan composition. As Stadium exist on the cross roads of Pionyrska and Sportovni it supplement around area of its tactic form an closely interact with park "Luzanky" thanks to it's glass fasade. The building is designed to meet every safety regulations regarding evacuation routes and required medical care. It also carries a number of place improvements not only technical and functional, but a lot of with architectural part of view.

moving objects tracking
Bradáč, František ; Gogol, František (referee) ; Richter, Miloslav (advisor)
The thesis deals with founding and tracking of moving objects inside of visual field and prediction of their future position. The created methods combine few approaches for solution this problem. First, the most probable of the static part of the observed scene is created. Then this model is used to detect moving objects. The correspondence of objects between two consecutive pictures is performed by analyzing of motion of these objects. For analyzing of motion of the objects optical flow is used. Prediction of the future position is performed by Kalman filter. Providing suitable condition these methods are able to track the moving objects even if these objects are passing closely or colliding. The methods are implemented in language C++ and their functionality was verified by sample with scanned non static scene.
