Effect of HFS Based Feature Selection on Cluster Analysis
Malásek, Jan ; Klusáček, Jan (referee) ; Honzík, Petr (advisor)
Master´s thesis is focused on cluster analysis. Clustering has its roots in many areas, including data mining, statistics, biology and machine learning. The aim of this thesis is to elaborate a recherche of cluster analysis methods, methods for determining number of clusters and a short survey of feature selection methods for unsupervised learning. The very important part of this thesis is software realization for comparing different cluster analysis methods focused on finding optimal number of clusters and sorting data points into correct classes. The program also consists of feature selection HFS method implementation. Experimental methods validation was processed in Matlab environment. The end of master´s thesis compares success of clustering methods using data with known output classes and assesses contribution of feature selection HFS method for unsupervised learning for quality of cluster analysis.

Feature Selection Based on Dynamic Mutual Information
Manga, Marek ; Klusáček, Jan (referee) ; Honzík, Petr (advisor)
This work analyzes and discuss a issue of implementation feature selection method called Dynamic mutual information (DMIFS). Original description of the DMIFS contains several irregularities, therefore DMIFS can not be implemented exactly as original method. Results of implemented DMIFS is compared with results of original DMIFS. This results shows that implemented DMIFS is similar to the DMIFS. Next part of the work describes design of two new methods based on the DMIFS. The first method called DmRMR merges mRMR and DMIFS. Better performance but worse stability of DmRMR was proved by several tests. The second method called WDMIFS is weighted version of the DMIFS based on AdaBoost algorithm. The WDMIFS has worse performance than DMIFS. Finnaly, manual for implementing DMIFS to RapidMiner and Weka is provided.

Simple artifical life framework
Klusáček, J.
Artificial life (AL) is a field of study dealing with computer models simulating life and its evolution. This article describes a simple framework created to work with an artificial life. Created framework works with simulation of behavior of single cell organism. In addition, it also simulates basic physics. Results of simulations are accessible through a web interface which allows observing the environment and details of each organism. Simple demo of realised program is aviable at address: http://klusacek.tk/~honza/sim/view.php?sim=sim.

Artificial neural network RCE
Maceček, Aleš ; Klusáček, Jan (referee) ; Jirsík, Václav (advisor)
This paper is focused on an artificial neural network RCE, especially describing the topology, properties and learning algorithm of the network. This paper describes program uTeachRCE developed for learning the RCE network and program RCEin3D, which is created to visualize the RCE network in 3D space. The RCE network is compared with a multilayer neural network with a learning algorithm backpropagation in the practical application of recognition letters. For a descriptions of the letters were chosen moments invariant to rotation, translation and scaling image.

Ingelligent Import of OSM into the Traffic Simulator TRASI
Muzika, Dávid ; Klusáček, Jan (referee) ; Honzík, Petr (advisor)
The thesis deals with the design and implementation of algorithms for import maps into the simulator TRASI. These algorithms are capable of import map from map portal OpenStreetMaps to the simulation environment. The work deals with adjusting the internal structure of the imported intersections, so that their structure was correct according to the rules of traffic. The work deals with the design and implementation of differential evolution for the design of the structure of intersections.

Date acquire system for Micropel's PLC network
Klusáček, Jan ; Valach, Soběslav (referee) ; Macho, Tomáš (advisor)
This paper deals with desgin and implementation of hardware and software for data acquisition device. Device is based on single board computer FoxBoard G20 which is placed on custom board which provide RS485 interface and short-term UPS. Device is runing Linux with device driver which enabling communication with Micropel PLCs across RS485 bus. Data are read from PLCs are saved to database and afterwards presented to user via web interface.

Design and analysis of high-speed induction motor
Klusáček, Jiří ; Ondrůšek, Čestmír (referee) ; Vítek, Ondřej (advisor)
Classical series production induction motors are usually adequate to most of the industrial application by range of rpm. For application requiring higher speed is traditionally used gearbox which is between motor and driven equipment. Nowadays, where are settings demands on efficiency operations and the most easily maintainance, so aim is to join driven equipment narrow with motors. When operating motors over 3000 rpm there are some proper problems. Generally, there is higher losses due to supply voltage from frequency converters and mechanically strength of rotor. This thesis provides a view on existing solutions of high speed induction machines. In the text there are mentioned options of using laminated rotor and solid rotor. Due to regard to angular speed of rotor there are mentioned the most important equations and knowledge, which are related to a mechanical strength of used materials and dimensions of machines. Later on is there mentioned groundwork, which when we are respecting them, we may improve the efficiency of machine. In this thesis is mentioned design, analyses and manufacturing process of high speed induction motor with solid rotor and copper layer at the surface. After that there are simulation of electromagnetic field through the use of finite element method in program FEMM. In the last chapter there are presented measured data of manufactured high speed motor and they are compared with calculations.

Analýza nezaměstnanosti a jejích důsledků v okrese Frýdek-Místek
Sajdáková, Soňa ; Nezdařilová, Eva (advisor) ; Klusáček, Jan (referee)
V diplomové práci se zabývám analýzou nezaměstnanosti v okrese Frýdek-Místek. V první části analyzuji nezaměstnanost podle dosaženého vzdělání, pohlaví, věku a podle délky evidence na úřadu práce. Druhá část je věnována dotazníkovému šetření, které probíhalo v měsíci září 2006 na Úřadu práce ve Frýdku-Místku. Výsledkem mé práce jsou doporučení a návrhy ve formě čerpání prostředků z Evropského sociálního fondu, systému investičních pobídek, snížení prostředků v oblasti pasivní politiky zaměstnanosti a její navýšení v oblasti aktivní politiky zaměstnanosti, zrušení či zastavení růstu minimální mzdy a dále také ve formě podpory počítačové gramotnosti s cílem zefektivnit způsob vyhledávání práce prostřednictvím nových technologií, především internetu.
