USB Host with PIC Microcontrollers
Kučera, Pavel ; Janoušek, Vladimír (referee) ; Hanáček, Petr (advisor)
The aim of master thesis is implementation of USB host in a microcontroller PIC. The thesis contains description of ways of peripherals to computer connections with detailed description of USB bus. There are also discussed several approaches in implementations USB host for embedded systems. A concept of layered USB host system is designed on the basis of analysis of the state of the art. Finally, the designed system is implemented in microcontroller. Resulting firmware of development kit is tested on real USB device.

Quality Evaulation of Structured Documentations Using Methods of Artificial Intelligence
Svrbíková, Simona ; Janoušek, Vladimír (referee) ; Homoliak, Ivan (advisor)
The motivation of this work is to provide evaluation simplicity and speedup of an extensive number of documentations with the same subject. The tool for automate evaluation was created and tested on the set of structured documentations originated from student´s projects with the same assignment. The tool uses an existing methods of the artificial intelligence for the purpose of the supervised learning. The source of the first attributes group are string-kernel functions using the criterion of the text strings similarity. Another group of attributes makes provision for properties like the structure of documentations, the stylistic, the length of chapters etc., which are statistically evaluated. These groups of attributes are joined together to achieve higher diversity of classified objects. The experiments present results achieved by using of neural networks, naive Bayes and SVM methods. The analysis of the data has been performed by data mining studio RapidMiner. The contribution of this work is to find out the classification usage possibilities in the case when classified objects have very similar properties in the feature space.

Automated Document Categorization
Sváček, Radim ; Janoušek, Vladimír (referee) ; Peringer, Petr (advisor)
This thesis deals with design and implementation of automated document categorization application. Text contains analysis of existing systems and description of classification methods. Thesis includes object oriented design of application including plugins. Application is implemented in C++ with possibility of functionality extension through plugins. Application aims to simplify work with unsorted documents through their organization into directory structure based on informations extracted from files, including their metadata.

Simple 3D Printer Simulator
Čillo, Vladimír ; Janoušek, Vladimír (referee) ; Peringer, Petr (advisor)
This thesis deals with design and implementation of 3D printer simulator in C++ using Qt. The simulator assumes a printer based on widely used method of 3D print - Fused Deposition Modeling. An input of simulator is a 3D model in STL file format. For the 3D model simulator provides an estimate of the total print time. Simulation also includes visualization of 3D print. The result is a cross-plaform program tested under Linux and Windows. Functionality of simulator has been tested by several experiments.

Sport Assistant for iOS
Fišer, Jakub ; Janoušek, Vladimír (referee) ; Hrubý, Martin (advisor)
The aim of this thesis was to create a mobile phone application for iOS, that would be used for recording all sport activities of a person. The application can record activity using GPS or count the exercise manually, automatically at time intervals or by motion sensor. For recognition of moves while using motion sensor was developed a library called Motion Recognizer. The application uses HealthKit framework. The application also offers an opportunity of planning a sport activity by using Trainer objects. It uses Core Data framework while working with data and it backs up the data on iCloud.

Code Generation from Object Oriented Petri Nets
Hanák, Martin ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
This thesis describes opinions about generating code from PNtalk language into more standard object orinted languages, such as C++ or Java. Goal is to construct model of the formalism of Object Oriented Petri Nets (OOPN), represented in PNtalk languege in mentioned languages. This model should be simlpier and more effective than actual implementation in Smalltalk language. Thesis also contains ideas about abstactization the code generator to be able to generate code in various languages.

Cryptanalysis of Symmetric Encryption Algorithms Using Genetic Programming
Smetka, Tomáš ; Janoušek, Vladimír (referee) ; Homoliak, Ivan (advisor)
This diploma thesis deals with the cryptanalysis of symmetric encryption algorithms. The aim of this thesis is to show different point of view on this issues. The dissimilar way, compared to the recent methods, lies in the use of the power of evolutionary principles which are in the cryptanalytic system applied with help of genetic programming. In the theoretical part the cryptography, cryptanalysis of symmetric encryption algorithms and genetic programming are described. On the ground of the obtained information a project of cryptanalytic system which uses evolutionary principles is represented. Practical part deals with implementation of symmetric encrypting algorithm, linear cryptanalysis and simulation instrument of genetic programming. The end of the thesis represents experiments together with projected cryptanalytic system which uses genetic programming and evaluates reached results.
