Project of wiring system with intelligent elements for family house
Lengyel, Ladislav ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
The goal of this bachelor work was first of all the theoretical introducing to the project documentation and to the question of intelligent electrical installation. The first part of the bachelor work consists of terms and definitions of principles for creating the project documentation of electrical installation. With the view of the pages’ limitedness, it is not possible to describe in detail all the terms principles and standards used in creating of electrical installation. Because of that, the work focuses on the heavy current part of the technical documentation only. The next part of the work is focused on the question of intelligent electrical installation, its division and applicable possibilities in family houses. The advantages of the system installation in comparison to classical. In this part are further analyzed and described the different systems of different manufacturers of intelligent electrical installations. The closing part focuses on the blueprint of the project documentation of heavy current distributions. The distributions of the electrical installation for the family houses are realized with the help of intelligent elements from ABB company of the KNX system. This part furthermore focuses on the proper selection of system installation, placing of the distributions and elements of installations, inclusive of components of intelligent installation and a blueprint of subsidiary apartment distributer. Then it deals with the calculation of heat loss of the object and the selection of proper head pump related to it. With the help of determined power take-off the main breaker used in the apartment distributing board is appointed and the conjunction of the main residence wiring related to it.

Singular Initial Value Problem for Ordinary Differential and Integrodifferential Equations
Archalousová, Olga ; Beránek, Jaroslav (referee) ; Růžičková,, Miroslava (referee) ; Šmarda, Zdeněk (advisor)
The thesis deals with qualitative properties of solutions of singular initial value problems for ordinary differential and integrodifferential equations which occur in the theory of linear and nonlinear electrical circuits and the theory of therminionic currents. The research is concentrated especially on questions of existence and uniqueness of solutions, asymptotic estimates of solutions and modications of Adomian decomposition method for singular initial problems. Solution algoritms are derived for scalar differential equations of Lane-Emden type using Taylor series and modication of the Adomian decomposition method. For certain classes of nonlinear of integrodifferential equations asymptotic expansions of solutions are constructed in a neighbourhood of a singular point. By means of the combination of Wazewski's topological method and Schauder xed-point theorem there are proved asymptotic estimates of solutions in a region which is homeomorphic to a cone having vertex coinciding with the initial point. Using Banach xed-point theorem the uniqueness of a solution of the singular initial value problem is proved for systems of integrodifferential equations of Volterra and Fredholm type including implicit systems. Moreover, conditions of continuous dependence of a solution on a parameter are determined. Obtained results are presented in illustrative examples.

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.

Electric Circuits Simulations
Šulc, Jiří ; Šátek, Václav (referee) ; Kunovský, Jiří (advisor)
The aim of this bachelor's thesis was the design of elementary graphic computational editor in which quality schema designs of electrical circuits can be created easily and fast. The application is further able to automatically generate the system of equations describing the designed circuit which can be used in the TKSL simulation system for displaying of the solutions. The application is designed for student's use in order to support the teaching of the Circuit Theory. The bachelor's thesis further deals with the problem solving of differential equations by the way of numerical integration methods with direct use of the Taylor series. The complexity of the analytical and numerical algorithm of the differential equations in solving electrical circuits is analyzed on the examples.
