Electrical Circuit Simulator
Dušek, Dominik ; Ježek, Pavel (advisor) ; Holan, Tomáš (referee)
The goals of this work were to create an extendable library for electrical circuit simulation and a simple editor for interactive electrical circuit forming.The library was written in C++ language. It uses following methods. Trapezoidal method for solving ordinary differential equations for simulation time-dependable electrical elements.Newton method for solving nonlinear equations for simulation of electrical elements with nonlinear Volt-Ampere characteristics. Modified nodal analysis is used for circuit equation formulation, and modified Gaussian elimination for solving linear equations ergo for solution of modified nodal analysis.Editor was written in C# language. The editor is graphic interface which allows to user forming electrical circuits in diagram representation. The editor also allows simulating electrical circuits via mentioned above library and generating time-vol tage graphs of circuit, from data gained by simulation. In the editor and in the library are implemented these electrical elements: independent voltage sources, independent current sources, ideal resistors, ideal capacitors and ideal inductors.

Segmentation and classification of LIDAR data
Dušek, Dominik ; Šorel, Michal (advisor) ; Obdržálek, David (referee)
The goal of this work was to design fast and simple methods for processing point-cloud-data of urban areas for virtual reality applications. For the visualization of methods, we developed a simple renderer written in C++ and HLSL. The renderer is based on DirectX 11. For point-cloud processing, we designed a method based on height-histograms for filtering ground points out of point cloud. We also proposed a parallel method for point cloud segmentation based on the region growing algorithm. The individual segments are then tested by simple rules to check if it is or it is not corresponding to a predefined object.
