Audio processing - filters and editing
Keznikl, Jaroslav ; Poch, Tomáš (advisor) ; Kofroň, Jan (referee)
The subject of this work is to analyse and implement some of the methods used in programs for sound processing. The work consists of two parts. The theoretical part contains a description of methods, procedures and data structures used in this area. It describes the process of sound sampling, structure of the WAVE format and explains the principles of basic digital audio fi lters. The practical part is formed from the implementation of some mentioned methods in the visual audio editor. The program, entitled AEditor, allows projection of the track in the main window, its playing, editing and the application of digital fi lters, with the preview of the filter setting in real time.

Paintball 3D for Symbian
Míšek, Jakub ; Zavoral, Filip (advisor) ; Poch, Tomáš (referee)
In the present work I'm describing construction of the computer game which is featured by using real time rendering. The work is targeted for implementation on cell phones with Symbian® OS. The work describes techniques of software rendering of threedimensional scene, vector animation and managing and representation of used data. Realization of simple artificial intelligence or multiplayer support is described too. All these features are implemented in attached application.

Amarok Speech Control
Kerpl, Lukáš ; Semecký, Jiří (advisor) ; Poch, Tomáš (referee)
In the presented work we study voice control of Amarok music player. The problem of controlling computer using speech is divided into several parts. In the rst part, we need to recognize what user says. In the last one, we should be able to answer to the user or give him some information. In between of these parts, we need to control the program, in our case the Amarok media player. In this work we describe all of these parts, as well as theirs conjunction into working program. Description of the usage of this program and even description of used libraries including potential alternatives is included. The last chapter, Usage and future development, considers the contributions of this program and computer voice control in general at the current time and in the future.

Guitar effects with automatic parameter setting
Fábry, Branislav ; Poch, Tomáš (advisor) ; Kofroň, Jan (referee)
The subject of this work is to implement a set of guitar sound effects and an application able to suggest effect parameters to achieve particular sound. The application (called ReSounder) will analyze original signal (e.g. clear guitar) together with the signal user want to achieve. The goal is to develop appropriate algorithms and metrics for signal comparing. The effects are implemented with using VST software development kit by Steinberg, which is used by majority of music software on the PC platform. At the beginning of this work, the reader is introduced to the problematic of digital audio and digital sound recording/processing, the main part of thesis explains the design decisions and implementation details of ReSounder. The results of application on real samples are evaluated in the conclusion.

Investment Strategies Simulator
Helešic, Tomáš ; Šerý, Ondřej (advisor) ; Poch, Tomáš (referee)
Title: Investment Strategies Simulator Author: Tomáš Helešic Department: Department of Software Engineering Supervisor: RNDr. Ondřej Šerý Supervisor's e-mail address: ondrej.sery@d3s.mff.cuni.cz Abstract: The goal of this thesis is the creation of an investment strategies simulator. The resulting program allows users to download current and historical stock data, visualize it using charts and implement on it the tools of technical analysis. These components are designed and linked to create fully worthwhile environment for the creation, evaluation and representation of user strategies. Keywords: Investment strategies; Technical analysis, Scripting;

Using Java PathFinder for Construction of Abstractions of Java Programs
Yuldashev, Nodir ; Parízek, Pavel (advisor) ; Poch, Tomáš (referee)
The growing complexity of software systems makes the verification of the systems very difficult. Techniques of formal verification and analysis are used to find bugs in the code, or to prove that the code satisfies some properties. A popular automated verification technique is model checking, which uses state space traversal. However, model checking is prone to state explosion and therefore does not scale to complex multi-threaded software systems. Common solution to this problem (state explosion) is to create an abstraction of the target system, and then verify only the abstraction. We have designed and implemented a tool for construction of abstraction of Java components in behavior protocols, which is based on the Java PathFinder model checker. Results of experiments on several non-trivial components show that the tool can be used in practice.

Editor for project IVE - objects and areas
Vorba, Jiří ; Brom, Cyril (advisor) ; Poch, Tomáš (referee)
The main goal of this work is to implement an editor for IVE which is the simulator of virtual humans developed at MFF UK. Our editor should primarily open up IVE for teaching of algorithms for control of virtual humans. The part of the work is also the search from field of tools for prototyping control algorithms of virtual agents in computer games and teaching applications. There is also introduced the project IVE itself. Also our own demo world was made for testing purposes and there arised two tutorials which are part of the extensive user documentation.

Level of detail AI for a simulation of a large artificial environment
Zíta, Petr ; Brom, Cyril (advisor) ; Poch, Tomáš (referee)
Level Of Detail techniques (shortly LOD) are well known in computer graphics, but they are applied also in complex simulations and virtual worlds (aka LOD AI ). On the same principle we can simplify the simulation of behavior in less important places for user and signi cantly decrease simulation complexity and system resources. In this thesis different ways of LOD AI techniques functioning in particular applications will be studied and then the formal de nitions of LOD AI techniques usage in simulations will be introduced. We will also outline common problems that LOD AI techniques implementations usually face and propose abstract algorithms for solution. We will also introduce additional LOD AI techniques of LOD in uences and LOD expirations with its concrete implementation in framework IVE and include appropriate observations of result quality.
