Hardware-Based Acceleration of Image Filtration
Zelinka, Martin ; Slaný, Karel (referee) ; Vašíček, Zdeněk (advisor)
This bachelor's thesis deals with the hardware-based acceleration of image filtration using FIR filters. Define basic concept about digital image, describes the principle of filtration and briefly explains the techniques used to detect edges in an image and smoothing the image. The main aim of this work is the analysis of several acceleration methods of FIR filters, which are suitable for implementation in hardware, and the subsequent implementation of the selected method with the possibility of configuration changes at runtime with regard to the maximum throughput. In conclusion of this work it is described the evaluation of the method and made compared with the optimal software implementations.

Modeling the movement of people when organizing mass cultural events
Zelinka, Martin ; Apeltauer, Tomáš (referee) ; Okřinová, Petra (advisor)
The thesis deals with the movement of people in the event of mass events where a large number of people accumulate and thus the risks associated with problematic of so-called soft target. The study deals with the movement of people, taking into account the behavior of visitors, as well as the influence of individuals, couples or groups, as well as the possible movement of evacuated following a critical event. As the target of the analysis is the International Folklore Festival in Červený Kostelec. The aim of the work is to optimize the layout of the festival venue, adjacent areas and accompanying events in its surroundings so as to ensure maximum safety for the participants and eliminate crowd phenomena under different scenarios. The numerical model of the festival with the wider environment created by the Pathfinder software tool will serve as a basis for optimizing the solution.

Influence of Glottal Shape of Human Vocal Fold on its Modal Characteristics
Zelinka, Martin ; Švancara, Pavel (referee) ; Hájek, Petr (advisor)
The main goal of the bachelor thesis is to create a parametric model with a variable angle of the human vocal fold and to determine the first two frequencies of vocal fold oscillations for all angles from -40 ° to + 40 °. The result is supported by a review of the anatomy of the human vocal system, the creation and modification of the voice, and current models of the human vocal fold. The model used for this work is created in the 3D CAD Inventor model software. Modal analysis is solved in the computer program ANSYS Workbench, solved using finite element methods.

Fast Detection of Natural Objects
Zelinka, Martin ; Bartl, Vojtěch (referee) ; Šimon, Martin (advisor)
Thesis deals with the detection and localization of dogs in the image. It analyzes computer vision techniques suitable for solving this problem. It is designed and then implemented solution. Data set of images representing the object of the search and the data set of negative images are created. The resulting solution is finally subjected to training in order to determine the best parameters for used algorithms. The resulting program is included in the attached DVD.

A Fault Injection Bug Hunting Tool Based on Systemtap
Zelinka, Martin ; Smrčka, Aleš (referee) ; Vojnar, Tomáš (advisor)
This work describes different methods of fault injection, the principles of system calls in operating system Linux and the Systemtap tool. The main aim of thesis is design and implementation of the application that work on the principle of fault injection into the system calls using Systemtap tool. Implemented application automatically identifies the existing system calls with the error return values, which are then replaced the original system calls return value.

Analysis of a Voice Propagation around the Human Body
Zelinka, Martin ; Švancara, Pavel (referee) ; Hájek, Petr (advisor)
The main objective of this thesis is to create a suitable realistic 3D model of the human body using photogrammetry and then to perform harmonic acoustic analysis in order to determine the reflection surfaces on the human body and the values of acoustic pressure with its level in the production of the human voice. The result of this work is supported by a search of anatomy and physiology of the vocal tract including models describing the propagation of the human voice in the vocal tract and, last but not least, by comparing the obtained results with previous works.

Changing interpretation of the role of the communist resistence at the Prague uprising
Zelinka, Martin ; Koura, Petr (advisor) ; Parkan, František (referee)
The Prague uprising signified the end of the Second World War in Protectorate of Bohemia and Moravia. As the Soviet and American armies progressed through the country towards Prague and the war was apparently soon to come to an end, Czechoslovaks themselves wanted to take part in the resistance against the Nazi oppression. The uprising was also a turning point for the succesful liberation of Prague. After the Czechoslovak communist party seized power in February 1948, the way the public perceived the uprising had to be changed to fit the party's interpretation, purposely overlooking the contribution of any non-communist resistence. This ideologically suitable interpretation had to be accepted even by the main leader of the uprising. The aforementioned interpretation can still be seen in historiographic books, even those published after the Velvet Revolution. Interpretation of the same event with the targeted use of words and phrases allows for different sounds and thus influences the reader. Targeted use of historical events can achieve the long-term prevalence of rumors, the refutation of which is a necessity and the work of historians. On the example of key moments of the uprising, such as its spontaneous beginning, the involvement of The Russian Liberation Army or the surrender of German troops...
