Tool for Communication Support Extern Participants of Event
Kratochvíl, Jiří ; Rychlý, Marek (referee) ; Kreslíková, Jitka (advisor)
The purpose of this thesis was to create application to support communication and ensuring participation of extern participants (sponsors, supporters) of an event such as conference, festival and more. Application provides support for communication between organizers and participants and o ers management of all necessary data associated with organizing event. The thesis also describes methods of project management and standards applicable for this issues. The PMBOK standard was described in detail, which was used together with ARIS methodic for application design in terms of communication, procurement and stakeholders.

Tooth Detection on Jaw 3D Computer Polygonal Model
Hulík, Rostislav ; Španěl, Michal (referee) ; Kršek, Přemysl (advisor)
This document discusses a concept and implementation of algorithms for teeth detection on 3D polygonal jaw model. At first, I describe possible shape detection techniques on three dimensional computer model, including utilization just in my case. After it, I analyze filtration problems of obtained model segments in order to reliably separate regions of tooth-arch from the rest of jaw. I included all these pieces of knowledge into a final application. Here, it is possible to choose from two user interfaces, first, classic user interface which demonstrates possible utilization in real world and second, testing interface which demonstrates functions of each detection and filtration method used in program and their effect on detection. Application is written in C++ language in development environment of MS Visual Studio 2005 and compiled with MS VS internal compiler. Tested was under MS Windows XP and MS Windows Vista OS.

Identification of pauses in noisy speech signal
Kepák, Petr ; Míča, Ivan (referee) ; Smékal, Zdeněk (advisor)
The basic problem of speech is a complete separation of the natural noise which arise from correct articulation of voiced and unvoiced consonants from noise and disturbance environment. Objective of this master’s thesis is to find an effective method that could identify the pauses without speech activity, which can identify the properties of noise and disturbance. Once the noise is correctly identified, it is already possible to use different methods for its removal. The master’s thesis describes two methods of pauses identification. These methods are programmed in Matlab and tested on nine speech recordings. Methods analysis of the results was performed using the ROC (Receiver Operating Characteristic) curves. In the end are summarized results analysis of created methods.

Statistical analysis of interval data
Troshkov, Kirill ; Antoch, Jaromír (advisor) ; Branda, Martin (referee)
Traditional statistical analysis starts with computing the basic statisti- cal characteristics such as the population mean E, population variance V , cova- riance and correlation. In computing these characteristics, it is usually assumed that the corresponding data values are known exactly. In real life there are many situations in which a more complete information can be achieved by describing a set of statistical units in terms of interval data. For example, daily tempera- tures registered as minimum and maximum values offer a more realistic view on the weather conditions variations with respect to the simple average values. In environmental analysis, we observe a pollution level x(t) in a lake at different mo- ments of time t, and we would like to estimate standard statistical characteristics such as mean, variance and correlation with other measurements. Another exam- ple can be given by financial series. The minimum and the maximum transaction prices recorded daily for a set of stocks represent a more relevant information for experts in order to evaluate the stocks tendency and volatility in the same day. We must therefore modify the existing statistical algorithms to process such interval data. In this work we will analyze algorithms and their modifications for computing various statistics under...

Analysis of salaries and wages in the capital city of Prague
Jermář, Martin ; Löster, Tomáš (advisor) ; Šimpach, Ondřej (referee)
The aim of the bachelor thesis is to analyse the development of wages and salaries in Prague, the capital city of the Czech Republic by using statistical methods. The thesis includes a general description of terms of salary and wage sphere, time series and selected applied statistical methods. In practical part the analysis of development of wages and salaries in Prague will be performed using the rates of dynamics. Further, time series predictions will be created using adaptive methods. The analysis should familiarize the reader with wage and salary developments for the period from 2011 to 2016 and outline the predictions of possible values in 2017. The results of the thesis show a higher increase in average and median monthly earnings in a wage sphere, increasing disproportions in monthly earning between men and women and bigger disproportions in monthly earnings in the wage sphere. Based on predictions performed the growth of wages and salaries is expected in 2017.
