Adjustable source feeded and controlled by USB bus
Staněk, Miroslav ; Frýza, Tomáš (referee) ; Kolouch, Jaromír (advisor)
The aim of this bachelor’s thesis is concept and realization of voltage source which is controlled and feeded by Universal Serial Bus. There will be presented whole design, execution, development progress and finalization of this project in the following text. This source must boost and buck standard voltage from USB. So it will be necessary using two source lines. Microcontroller of AVR family will be used in the direct part of this adjustable source. Into this microcontroller will be embedded USB interface by the software solution. The microcontroller isn‘t used only for communication with PC by the computer programme, but it is also used for switching the source lines by the PWM modulation. According to the minimum output voltage scale (0 – 15 V) this source is useful for a wide spectrum of low- power devices. This equipment could be helpful together with laptop to charging devices (cell phone, camera, pocket osciloscope etc.), which are carried with notebook for doing outdoor activities and measurements.

Simple text-independent voice lock - speaker verification software system
Kotulek, Milan ; Dolenský,, Jan (referee) ; Staněk, Miroslav (advisor)
A brief introduction into biometrics is described in this thesis leading to description and to design a solution of verification system using speech analysis. The designed system provides firstly basic signal processing, then vowel recognition in fluent Czech speech. For each found vowel, observed speech features are calculated. The created GUI application was tested on created speaker database and its efficiency is approximately 54 % for short testing utterances, and approx. 88 % for long testing utterances respectively.

Statistical Processing of Speech Features
Svozil, Martin ; Dolenský,, Jan (referee) ; Staněk, Miroslav (advisor)
This diploma thesis deals with the speech signal processing and vowel analysis mainly to uncover differences in speech features depending on the emotional state of speaker. Created application ARePa for speech signal processing was developer in Matlab environment and contains Graphical User Interface (GUI) for better manipulation with ARePa and analysed records. The application includes a complete analysis of the speech signal and further comparison of current feature with feature values from database using histograms. Of course, the developer application allows the archivation of currently analysed records into database.

Software analysator and tuner of vocal records
Smatana, Tomáš ; Dolenský,, Jan (referee) ; Staněk, Miroslav (advisor)
This thesis deals with the analysis methods used to fundamental frequency detection and methods for changing the fundamental frequency of the audio signal containing vocals. It also explores general musical intonation theory. On the basis of this analysis, suitable methods are selected for the follow realization software fine-tuning vocal audio signal.

Multimedia signal processing
Staněk, Miroslav ; Pospíšil, Radek (referee) ; Sigmund, Milan (advisor)
The aim of this thesis is creation the appropriate multimedia support for signals and system with continuous time. The understanding of this issue is very important, because the obligatory subject Signals and systems, exactly BSIS, is taught at the EST bachelor degree. The understanding is also necessary prerequisite to successful understanding next topics in other related subjects. The next part of this thesis is focused on one dimension discrete signals. Concretely, the aim of this part is a realization of software system. Designed system has some basic operations (the signal energy, the number of signal zero crossing etc.) with sound files and also some advance functions e.g. vowel seeking and separating in fluent speech. The system is divided into two main parts. The first one analyzes sound files, creates the new sound file with wanted vowel and matrices with important parameters for other processing. The second program computes with given data, which statistically evaluates in other steps. The final system can be useful for speaker recognition, his emotional status etc.

Applications of Microcomputer-Based Laboratories in Inquiry-Based Science Education.
STANĚK, Miroslav
The main aim of the propounded work is based on the using of computer technology and experimental laboratory systems in science education. In this work there is a study of the role and function of the interactive teaching. We think about features of the school experiment in the thesis. School experiments are divided into simple typology in this work, according to the level of individualization pupil's activities into following types: demonstration activities (teacher based), student laboratory works and student research activities. The role of computer technology in each of the following experiments is to provide tools for measurement, visualization and analysis of experiment. In the case of student research activities IT also comes into the role of guide in experiment and it provides its theoretical and didactic background. Information Technologies are showed in the thesis as a key tool to the didactic transformation in science education.

Budgeting Process and Economy Analysis in a chosen Municipality
Staněk, Miroslav ; Stejskalová, Irena (advisor) ; Kubová, Olga (referee)
The subject of the thesis, the course of the budgetary process and economic analysis of Pelhřimov indebtedness of the town and the effect of this moment of crisis to profit center. On the basis of theoretical facts and practical findings was analyzed past financial management of the city in 2006 - 2009. The thesis concentrates especially on the most significant budget item, which means they come from and derive income. In the end was analysed financing of municipal budget, debt and built the financial outlook.

Analysis and design of the portal for the disabled
Staněk, Miroslav ; Molnár, Zdeněk (advisor) ; Trčka, Adam (referee)
The main goal of this diploma thesis is the creation of the bases for the project realization with the output in the form of the web portal for disabled fellow - citizens and people with special needs, e.g. elderly, foreigners etc. Mentioned bases form especially the analytic part of the project and description and realization of the most activities, which are in some way related to the work of the analyst. One of the most important contributions of this diploma thesis is the identification of the issue of disabled people, the identification of current available significant and germane information within the framework and especially the proposal and recommendation for developing the present situation. This diploma thesis forms finally the indispensable benefit for resolution of the whole project, because it contains its substantial part. The thesis is divided into several comprehensive and connected blocks. There are the main goals and reasons leading to choosing this subject described in the introduction, as well as the premises and limitations of realization of this diploma thesis. The author continues with identification of the information needs of possible portal users, whereas the emphasis is placed on the status and number of disabled citizens in the Czech Republic. Another important part of this thesis is the construction and description of the project plan, which includes the activities and occurrences needed for the realization of the overall solution. The remaining structure of the thesis is determined by a sequence of phases and activities described in the project plan. The evaluation of achieved goal's levels and detail identification of the contributions is made at the close of this diploma thesis.

Usage of the UCP Method (Use Case Point Analysis) in Estimation of Effort in SW Development
Staněk, Miroslav ; Stanovská, Iva (advisor) ; Zelenka, Ivo (referee)
This bachelor project takes up the subject of summarizing selected methods of analyzing effort of software development. The aim of the project is to explain the calculation progress of some of the methods, while the UCP method and other methods based on the model are emphasized. The UCP method mentioned is used on a practical example and its realization facilitates the comprehension of the essence how single weights of the factors are adjusted and demonstrates the influence of every factor on the final estimate of effort of development. All of the information about the methods are based on previous thorough study of available literature and information sources. Gathered knowledge is used in the realization of the example as well.
