The purpose of this work has been to describe some techniques which are normally used for cluster data analysis process of unsupervised learning. The thesis consists of two parts. The first part of thesis has been focused on some algorithms theory describing advantages and disadvantages of each discussed method and validation of clusters quality. There are many ways how to estimate and compute clustering quality based on internal and external knowledge which is mentioned in this part. A good technique of clustering quality validation is one of the most important parts in cluster analysis. The second part of thesis deals with implementation of different clustering techniques and programs on real datasets and their comparison with true dataset partitioning and published related work.

This piece of work deals with a philosophy of design adaptive controller, which is based on knowledge of mathematical model controlled plant. This master thesis is focused on closed-loop on-line parametric identification methods. An estimation of model´s parametres is solved by two main concepts: recursive leastsquare algorithms and neural estimators. In case of least-squares algorithm the strategy of preventing the typical problems are solved here. For instance numerical stability, accurecy and restricted forgetting. Back Propagation and Marquardt- Levenberg algorithm were choosen to represent artificial inteligence. There is still a little supermacy on the side of methods based on least-squares algorithm. To compare individual algorithms the grafical interface in MATLAB/Simulink was created.

Work is focused on wireless sensor networks.The main theme is the mobility and localization in these networks. This work describes different methods and capabilities of mobile and localization schemes. This work describes a new localization protocol for wireless sensor networks. Finally, there is included a new protocol in the simulation at Network Simulator 2 and evaluate the results obtained.

The presented master's thesis deals with the issue of storing and sharing data from medical imaging systems. This thesis, inter alia, consists of organizational and informatics aspects of medical imaging systems data in multicentric studies containing MRI brain images. This thesis also includes technical design of a web-based application for image data sharing including a web interface suitable for manipulation with the image data stored in a database.

The aim of this master‘s thesis is design and construction of home meteo weather station, the choice of applicable temperature, humidity and pressure sensors and characterization of workable device of station. The core of the station is microcontroller ATmega8 used for process data from sensors. Evaluative criteria for choice of sensors will be comunicate interface, accuracy, operating range, current drain and other aspects. Outer transmittin unit measure air temperature and relative humidity. These data are trasmitted by wireless radio module to interior receiving unit, that measure interior temperature and atmospherical pressure and represent measured data to LCD display including dew point. The data are transmitting to the internet and storing in the database. Measured values are available on the web page where you can display the graphs of last measured values.

This work focuses on issues relating to the perfusion analysis. The aim of this work is to perform experimental measurements of the phantom and then evaluate the perfusion curves. This curves are used to himation of perfusion hemodynamic parameters, which indicates important informatik about monitoring area. All processes associated with the designation and evaluation are performed in a program named Matlab. The output of work is a system that provides the reader into the problem of perfusion analysis and allows him to understand and know what is the meaning od analysis, what demands are placed on the evaluation and what is the result of this perfusion analysis.

This work deals with setting of dependability of static electricity meters. The first two chapters deal about electricity meters and dependability in general than there are introduced three possible ways for getting dependability parameters. The first methode is data collection from the field. The second methode is reliability prediction from component's reliability. The third methode is aging life tests. Conclusion contains evaluation of results and highligting of importance for practical usage.

This master’s thesis deals with design and implementation of electric energy meter with support of automatic remote data collection. For the collecting of measured data is used narrowband PLC technology. The theoretical part describes the basic properties and standards of narrowband PLC technology, such as types of coupling circuits, modulations, frequency bands and interference problems. In the practical part, there is description of selected parts, such as control circuit power meter, modem, microcontroller and UART to USB converter. There are further described basic properties of narrowband PLC modem ST7570 by STMicroelectronics. The final chapter, implementation of the device, deals with designs of circuit PLC modem ST7570, power meter ADE7753 and converter USB to UART CP2102.

The thesis is focused on the description of LTE system in terms of signaling on interfaces of LTE and EPC subsystems, such as UE initial network connection. The next section describes the types of diagnostic methods for mobile networks using OSS, drive testing and flow analysis. The thesis also aims at description of key performance indicators (RSRP, RSSI, etc.) and the proposal for measuring of the LTE network physical layer and the data transmission speed.
