Design of formula SAE rear axle
Tomášek, Pavel ; Blaťák, Ondřej (referee) ; Porteš, Petr (advisor)
This thesis is concerned with the design of Formula SAE rear axle suspension and spring suspension. First part of the thesis deals with the preliminary desing and is followed by the kinematic analysis and optimalization of the rear axle geometric ordering. Next part is related to the verification of the spring suspension characteristics. Both these parts were worked up with the aid of the software ADAMS. Last part of the thesis includes the engineering desing of rear axle components and stress and deformation analysis.

Speaker Diarization
Tomášek, Pavel ; Karafiát, Martin (referee) ; Matějka, Pavel (advisor)
This work aims at a task of speaker diarization. The goal is to implement a system which is able to decide "who spoke when". Particular components of implementation are described. The main parts are feature extraction, voice activity detection, speaker segmentation and clustering and finally also postprocessing. This work also contains results of implemented system on test data including a description of evaluation. The test data comes from the NIST RT Evaluation 2005 - 2007 and the lowest error rate for this dataset is 18.52% DER. Results are compared with diarization system implemented by Marijn Huijbregts from The Netherlands, who worked on the same data in 2009 and reached 12.91% DER.

Recognition and Search in SKype Calls
Tomášek, Pavel ; Plchot, Oldřich (referee) ; Černocký, Jan (advisor)
The project aims at a system for recognition of Skype calls. One of the necessary project focuses is finding out a high-quality Skype recorder. Signal preprocessing (segmentation of speech/silence) and speech recognition follows. Another project interest is in choosing a presentation software, which meets the project needs. Essential part of this work is also indexing and search implementation. This project is a proof-of-concept and shows one of the ways of speech recognition utilization.

Comparison of Project Management Tools
Tomášek, Pavel ; Blažek, Petr (referee) ; Juřica, Pavel (advisor)
Thesis deals with evaluation of possibilities and conditions for application of key project management methods. Particular parts involve description and delimitation of chosen project management. Traditional methods that are represented by CPM and PERT methods. Furthermore, the thesis is enriched on the basis facts of the Theory of Constraints, which led to the creation of a separate project management system based on the Critical Chain method. This part is followed by an analysis and comparison of these methods in the phase of planning, managing and controlling from a perspective of single project case. Thesis is followed by the using of selected method in real environment conditions, its implementation and evaluation of risks and economic differences.

Using The Principles of Lean Production
Tomášek, Pavel ; Ratičák, Milan (referee) ; Juřica, Pavel (advisor)
This bachelor thesis is focused on improvement of production processes in company ABB s. r. o. in Brno which produces instrument transformers. This thesis describes the basics concepts of lean production. The reader learns about the problems of manufacturing company. In the next part the bachelor thesis analyzes and evaluates the current situation of production. There is a proposal of improvement in conclusion which affects the company´s production system that should increase the effectivity of production processes.
