Auxiliary inverters for electric traction
Polášek, Petr ; Pazdera, Ivo (referee) ; Červinka, Dalibor (advisor)
This thesis concerns with specified problems of an electric traction. It deals with the concept of module controlling EC motor of the voltage 24V and the current 100A. There are described possibilities and principles of controlling EC motor in detail. For controlling, the single-purpose IO MC33035, which is directly specified for it, is used. The thesis describes implementation of both testing and final versions of converter for a circulating pump drive of a cooling circuit in locomotives. The convertor is partly universal and can be used in other applications. According to the implemented convertor, a laboratory test and a model protocol were made. In the second part, the concept is described as well as the implementation of DC/DC conventor of output voltage of 24V and which is supplied by 12V battery. The specified output current is 4A. It is used for supplying of the controlling traction vehicle unit and is installed as a boost convertor which contains a resonance conventor. The presentation of measured parameters of the complete convertor is either a part of this thesis.

Automatic Detection and Cartographic Generalization of Spot Heights from Digital Terrain Models
Polášek, Petr ; Lysák, Jakub (advisor) ; Tippner, Aleš (referee)
The aim of this work is to design automatic detection of spot heights from airborne laser scanning data and its generalization. The first part is about the idea of spot height: the importance of spot heights for altimetry representation on maps and suggestions concerning the scatter of spot heights on maps. In the following part, different approaches for terrain critical points extraction (peaks, depressions, passes) from digital terrain models are described as suitable places for spot heights location. Further, we introduce a description of geomorphological characteristics of these points by which is possible to identify its significance and generalize them. In accordance to analysis of Základní mapa ČR and recommendation for spot heights location described in literature we designed own method of automatic generation and generalization spot heights from digital terrain models. This method were implemented and there is a description of the test data and results on the real data DMR 5G of the algorithm in the end of the work. Powered by TCPDF (www.tcpdf.org)

Map server visualizing the Albertov campus
Polášek, Petr ; Štych, Přemysl (advisor) ; Brůha, Lukáš (referee)
Map server visualizing the Albertov campus Abstract The basic aim of this work is to create an interactive web application which enables to display several map layers of the Albertov campus and its surroundings. The application will be providing information about university buildings and it will be created with Open Source tools MapServer and OpenLayers. In the first part the work deals with digital internet maps, web map services and with architecture of map servers. In the practical part are described both MapServer and OpenLayers and also the methodology of the work. Keywords: MapServer, OpenLayers, map server

Service-oriented simulation architecture
Polášek, Petr ; Sklenář, Jaroslav (referee) ; Kavička,, Antonín (referee) ; Češka, Milan (advisor)
This thesis focuses on design, modeling and simulation of heterogeneous systems with emphasis on discrete-event systems. It proposes service-oriented simulation architecture where modeling and simulation is treated as a service and establishes a DEVS Meta Language that is intended for implementation of simulation models based on the DEVS formalism. Special M\&S techniques are described and integration of existing simulation tools is discussed as well.
