The aim of this paper is to acquaint the readers with basic classification of wind turbine configuration by used electric generator, with speed and power control used in power plants and with mathematical model of wind and parts of power plant. Procedure of making model in applications Mathematica and MathModelica is described in the other part of this paper. There were made models of power plants with squirrel cage asynchronous generator, one with pitch control, the other with stall control. In the last part of the thesis comparison of model behavior of both models with the same input conditions was made.

This Master’s Thesis focuses on development and realization of analog system software simulator for simulation of various kinds and orders systems and for function verification of microcontrollers’ control systems. The development and realization of PSD controller is part of this thesis as well. The simulator is written in C++/CLI programming language which combines fast execution of native code and provides an advantage of managed code which has its execution managed by the .NET Framework. The data acquisition is performed via National Instrument’s USB multifunctional DAQ. The PSD regulator is realized by using modern ARM processor architecture.

The background research in this Master’s thesis is focused on swarm intelligence. Further, there are two experiments described. They are based on released publications and they study behaviour of a group of robots during a puck gathering and during a target search. The actual thesis follows a repetition of these experiments in Microsoft Robotics Developer Studio (RDS), a free robotics simulation environment. The realization of both experiments in RDS is documented in detail and the achieved results are evaluated and compared with the results described in the publications. In conclusion, the thesis summarizes basic features, advantages and disadvantages of developing in RDS, based on a personal experience.

This master thesis is focused on the sensitivity analysis of selected kinds of state reconstructors. They are realized in a general form, via direct and parallel programing. Quantity that determines the quality of sensitivity is output signal difference of the reconstructor with the general form of the system. Testing will be based on different initial state conditions and on the parameters change of the feedback A matrix due to the rested reconstructors.

The aim of this thesis is to create a power line transfer function generator in Matlab. Work on introduction explains the concept of power line and describes the different types of topologies and types of cables that power line are the most widely used today. It is also discussed PLC technology, its structure, characteristics of the transmission channel and interferences. The following are approach the types of the modeling of power line. More details are described generally modeling in the frequency (two-port network model), which is used in the created generator. The next section provides a power line model, whose principle is used in the generator. The following is a description of created the generator and comparison with FTW PLC Simulator. In conclusion, the thesis presents the results of simulations the transfer function, which show the magnitude and phase frequency characteristics of different topologies and parameters.

This master’s thesis is focused on the problems of designing telephone lines which are 7 km long with a step of 1 km. The thesis contains a detailed description of the basic parameters of metallic transmission lines. There is also briefly mentioned the issue of interfering the transmission lines. The main part is devoted to a system design of artificial lines connection, including printed circuit board design. The next section deals with a design of prototype controlling. The last part verifies the activity of implemented artificial lines.

This work deals with a theoretical analysis of contacting semiconductor chips using wire-bonding method. There are mentioned basic types of chips packages and their contacts. In the thesis is also described software Ansys. The number of the mechanical stress and deformation simulation within micro-wire during thermocompress process were made.

The main task of this master’s thesis is to simulate the routing protocol AODV (Adhoc On-Demand Distance Vector Routing) to the Network Simulator ns-3 environment, and to realize a model of MANET (Mobile Ad-hoc Network) network with the support of Quality Of Service (QoS). Further implement the protocol AODV in real devices and the involvement of such nodes in the simulation process using the simulator ns-3. This work provides the theoretical basics: it deals with the primary characteristics of MANET, describes in detail the routing protocols MANET with support of QoS, provides information about the Network Simulator ns-3 simulation environment, describes in detail the existing implementation solutions of the protocol AODV in to real devices and provides information about the methods of involvement real devices to the simulation.

The main topic of this master´s thesis is a practical simulation of wireless mobile networks. For this purpose, the model simulating urban enviroment in which mobile nodes move according to desgined trajectories was created. The parameters of transmitted signal and impact of obstacles in the way of propagation were examined by the simulation. Number of obstacles and type of material of given obstacle was taken into consideration.

The aim of this thesis was to ascertain with the measurement methods of passive optical networks and the creation of a simulation model that corresponds to the measured network and comparison of results. The first chapter deals with Triple Play services, which are focused on different services (transmission of television signals, voice and data transmission). Each service consists of a subchapter and presents a detailed description of the parameters associated with the transmission. The second chapter of the theoretical part consists of an analysis of passive optical networks according to termination method of FTTx optical fiber. Partial part of this chapter consists of description of standard passive optical networks APON, BPON, GPON and EPON. The EPON standard is explained in detail. The theoretical part of the thesis is concluded with a description of active elements that will form the laboratory measured network. Testing of designed passive optical network is performed in the practical part of the thesis. The measurement is divided into two chapters. The first chapter consist of measuring of the „inanimate network“, as there are missing active elements in the nominated net. Network measurements were done by a direct measuring method and reflectometric method. The second chapter of the practical part consists of measuring the parameters of quality of service (QoS). This chapter is divided into subchapters, such as: the measurement using RFC 2544 standard, the measurement using ITU-T standard Y.156 (EtherSam) and bit error rate testing (BERT). The practical part ends with a designed simulation network model, which was proposed in OptSim 5.2. The aim of the simulation model was to maximally resemble a real network, due to result comparison.
