Simulation of Stock Exchange
Šejnoha, Jiří ; Karásek, Michal (referee) ; Bálek, Martin (advisor)
The topic of this work is simulation of stock market. Studying the dependence of Prague stock exchange index PX depending on the macroeconomic parameters. It uses the connection methods, neural networks and random walks, where the random walk forward trained neural network functions as decision-making unit, normally used instead of linear approximation. Specially concerning the relationship of dependence PX on exchange rate U.S. dollar and Czech crown, gross domestic product of the Czech Republic and 2W repo rate. Simulation is performed using neural networks and linear approximation to the historical dates against them is then validated.

Web information system for web reality brokers
Vávra, Štěpán ; Karásek, Michal (referee) ; Bílý, Tomáš (advisor)
Title: Estate agency internet information system Author: Štěpán Vávra Department: Department of Applied Mathematics Supervisor: Mgr. Tomáš Bílý Supervisor's email address: tomby@kam.mff.cuni.cz Abstract: The aim of this work is to explore the possibilities offered by the PHP language in combination with the Apache web server and MySQL database in order to implement a web application. This web should be able to compete with other similar applications on the internet, especially in the field of real estate, both by its functionality and graphic design. A significant part of the task should consist of the design of the application. Consequently, our objective was not to find and use the most suitable framework or other tools of support, such as content management system. The programming phase of the project was then done using the methods of Object oriented programming. Keywords: web application, PHP, XHTML, JavaScript

Mouse Gestures
Dzurenko, Miroslav ; Karásek, Michal (referee) ; Bílý, Tomáš (advisor)
Computer mouse was invented more than forty years ago, but its real potential is not even used at present. Application Just Gestures extends mouse possibility with "mouse gestures" - gestures which are created in combination with mouse clicks and movements. This trajectory is recognized and executes specific command for any application or operating system, what makes work easier and faster. The aim of this work is to create an application for Microsoft Windows system based on neural network recognition. In regards to our specification, it is necessary to divide problem in to three basic parts - retrieving and processing mouse actions, learning, recognition of gestures and executing the adequate command.

Delimitation and transformations of metropolitan areas in transformation period in the Czechia
Karásek, Michal ; Novák, Jakub (advisor) ; Mulíček, Ondřej (referee)
The diploma thesis is focused on two main aims. The first aim of the thesis is to define proper metodology for delimitation of the metropolitan areas. On the basis of this metodology the metropolitan area of Prague, Plzeň, Brno and Ostrava are defined. The second main aim of this thesis is answer the question, whether transformation period influences development of process of metropolization or not. With this purpose concrete development tendencies in the delimitation metropolitan areas are analyzed. At first the development of concentration of population and jobs is concerned, after follows the analysis dealing with spatial mobility of the population within areas. In this context is covered development of intensity of commute and migration flows among different units of metropolitan area. The growing in mutual intensity of mobility among units of metropolitan areas indicates the development of cooperative ties in territory and also development of process of metropolization.

Selected algorithms for colour control
Karásek, Michal ; Průša, Zdeněk (referee) ; Rajmic, Pavel (advisor)
The Bachelor's thesis work follows the selected algorithms of the colour management. In the first part it adverts to the basis of the colour perception itself and explains the top important notion - colour event. Further it follows the issue of colour utilization in the computers and individual colour models. It deals with colour management, in the concrete by a transfer of gamuts from one facility to another one. In the next part the implementation of ICC profiles is analyzed, as well as the comparison of single methods of the gamut transfer and practical utilization of these transfers in computer programme Matlab.

Parkinson disease diagnosis using speech signal analysis
Karásek, Michal ; Smékal, Zdeněk (referee) ; Mekyska, Jiří (advisor)
The thesis deals with the recognition of Parkinson's disease from the speech signal. The first part refers to the principles of speech signals and speech signals by patients suffering from Parkinson's disease. Further, it continues to describe the issues of speech signals processing, basic symptoms used for diagnosis of Parkinson's disease (e. g. VAI, VSA, FCR, VOT etc.) and reduction of these symptoms. The next part focuses on a block diagram of the program for the diagnosis of Parkinson's disease. The main objective of this thesis is comparison of two methods of feature selection (mRMR and SFFS). For classification have selected two different methods were used. The first method is classification kNN and second method of classification is Gaussian mixture model (GMM).

Principles of trading on betting exchanges
Karásek, Michal ; Málek, Jiří (advisor) ; Moravec, Lukáš (referee)
Unlike traditional stock exchanges, where bonds, shares and financial derivatives are traded, on the betting exchanges there are traded probabilistic estimates of the results of sporting or social events. The market price of bets, namely the market implied probability is influenced by estimate of the outcome. The specificity of betting exchanges is also a short period to maturity of contracts, and the possibility to trade with the estimated result of one real world event in several sub-markets simultaneously. In theoretical analysis, we have defined the bet, the underlying asset, and the binary betting contract, which is traded on betting exchanges. We have described some practical aspects of trading. Properties of the probabilistic contracts are demonstrated on several examples. Finally, we constructed the mathematical model of a tennis match, which is based on a binomial valuation model. This allows us to compare the market price of a contract with the price recommended by the model.
