Retrospective Space Game for Two Players
Kimer, Tomáš ; Kaštil, Jan (referee) ; Pospíchal, Petr (advisor)
This bachelor's thesis describes the development of a computer game inspired by one of the first computer games ever - Spacewar!. The first part describes computer games and associated history, current status, their genres and retrospective games. The second part deals with hardware-accelerated computer graphics, focused on its history and discusses the graphics libraries, especially OpenGL. Next part is devoted to design of the developed game, addressing the movement of objects, collisions between them, effects using particle systems, controls for two players on one computer and a basic graphics user interface. Next chapter covers implementation in C++ language using OpenGL and SDL libraries and object oriented design. The final section is devoted to testing the resulting application, including analysis of user ratings.

Application for Demonstration of Hash Algorithms SHA-1 and SHA-2
Siska, Josef ; Petrlík, Jiří (referee) ; Novotňák, Jiří (advisor)
In this thesis, the theory related to the hash algorithms SHA-1 and SHA-2 is presented, along with a description of possible implementation of an application that demonstrates how these algorithms work. The first part of this thesis describes the principles of construction of hash functions, their use and history of selected hash functions. The two following chapters present conventions and algorithms of the SHA-1 and SHA-2. The next chapter describes the general concepts related to the attacks on the hash functions and selected attacks are presented in more detail. The last two chapters outline the design and implementation of an application that was created as part of this work. In the end the evaluation of results of this thesis and proposals for its possible continuation are presented.

Anti-Collision System Based on GPS
Varga, Marek ; Drahanský, Martin (referee) ; Orság, Filip (advisor)
Aircraft industry is constantly facing the need to increase security not only in the case of large machines, but also in the small aircraft. Many systems were established in order to inform the pilot of the impending hazard, where appropriate, about the location of the other aircraft. The main objective is to establish a facility which uses global position system for determining the position and imparts coordinates using wireless networks for subsequent determination of collision. The functions of satellites and GPS receivers, sending wireless data and collision calculation and synchronization of individual modules is described in detail.

Better Chaperone Bounds Using 3D Sensors
Tinka, Jan ; Beran, Vítězslav (referee) ; Najman, Pavel (advisor)
Room-scale tracking encourages users to move more freely and even walk. Even though there has been much research on making the limited physical workspace feel larger in the VR, these approaches have their limitations and require certain conditions to be met. This thesis proposes an alternative approach to the conventional play-area boundaries of high-end VR products such as the HTC Vive and Oculus Rift which are set by the user in a 2-D fashion as a means of enhance workspace utilization. A 3-D scanner is used to make a 3-D point-cloud model of the play area's surroundings. This model is then used to detect collisions and provide feedback to the user. Evaluation based on user tests showed that this approach can be useful, is well accepted by users and might be worth further research.

Predictive software for Earth collision with Near Eartch Objects
Stopka, Jiří ; Daněk, Vladimír (referee) ; Bartoněk, Jaroslav (advisor)
Aim of this bachelor’s thesis is to research and discuss the basics of orbital mechanics and their application on a real problem. The application of orbital mechanics is made by creating a software for predicting Earth’s collision with Near-Earth Objects in Borland Delphi 7 development enviroment. The created software should be able to predict close approaches of Earth and Near-Earth Objects in a time scale selected by user and issue a warning in case of a dangerous close approach.

Hash functions - characteristics, implementation and collisions
Karásek, Jan ; Sobotka, Jiří (referee) ; Lambertová, Petra (advisor)
Hash functions belong to elements of modern cryptography. Their task is to transfer the data expected on the entry into a unique bite sequence. Hash functions are used in many application areas, such as message integrity verification, information authentication, and are used in cryptographic protocols, to compare data and other applications. The goal of the master’s thesis is to characterize hash functions to describe their basic characteristics and use. Next task was to focus on one hash function, in particular MD5, and describe it properly. That means, to describe its construction, safety and possible attacks on this function. The last task was to implement this function and collisions. The introductory chapters describe the basic definition of hash function, the properties of the function. The chapters mention the methods preventing collisions and the areas were the hash functions are used. Further chapters are focused on the characteristics of various types of hash functions. These types include basic hash functions built on basic bit operations, perfect hash functions and cryptographic hash functions. After concluding the characteristics of hash functions, I devoted to practical matters. The thesis describes the basic appearance and control of the program and its individual functions which are explained theoretically. The following text describes the function MD5, its construction, safety risks and implementation. The last chapter refers to attacks on hash functions and describes the hash function tunneling method, brute force attack and dictionary attack.

Vliv aktivních bezpečnostních prvků na dopravu
Chmelíček, Patrik
The bachelor’s thesis deals with influence of active safety features on traffic. It describes their current condition and specifies technological possibilities of the features given the current trends in this branch and presents their use in agricultural machinery. Emphasis is placed mainly on modern assistive systems such as blind spot monitoring, emergency braking etc, lane keeping assistence etc. Second part of the thesis pursues sorting and analysis of the accident rate in Czech republic, European union and giving comparison to a countries from a different parts of the world, such as United states or Kazachstan. This research is followed by potential capability of active safety systems to reduce those accidents. Based on theese data, effectivity of active car safety features given economical aspects in traffic is judged.

Species-specific and individual predictors of birds' collisions with glass obstacles in the Czech Republic
Semeráková, Anna ; Sedláček, Ondřej (advisor) ; Viktora, Lukáš (referee)
Recent landscape transformation is associated with the emergence of various artificial obstacles that change the natural form of habitats and biocorridors of free-ranging animals. Glass obstacles represent a particular problem due to their transparency and reflectivity. Collisions with glass represent one of the most significant causes of bird mortality worldwide, accounting for over hundreds of millions bird deaths annually. Many authors consider this source of mortality to be completely non-selective. In that case, total collisions mortality would represent a function of population size. However, here I assume that the relationship between collision mortality and population size is more complex and that certain avian ecological groups may be differently susceptible to glass collisions based on their specific ecological characteristics. Long-term records of bird-glass collisions in the Czech Republic were provided by the Czech faunistic databases. These records were compared with the population size of analysed species and with selected ecological and morphological species characteristics. Consistently with the premise, I found out that the greatest amount of collision mortality is explained by the species' population size. However, other species characteristics, such as higher body weight,...
