Security design for system of remote quality measurement of electric power
Jakubíček, Michal ; Koutný, Martin (referee) ; Mlýnek, Petr (advisor)
Bachelor thesis in the first chapter deals with the concept of quality of electric power and its parameters. The next chapter is focused on systems that used remote data collection and the current direction of evolution of these systems. The third of the thesis discusses the symmetric and asymmetric cryptographic systéme and their main representatives. The asymmetric system is described by the principle of calculating RSA and Diffie–Hellman. The next part deals with selected libraries that can count large numbers. Through the establishment of key using the Diffie–Hellman with these libraries. The evaluation of the used library in terms of speed, number of elementary cycles and memory consumption is inculded in the chapter 5. The last chapter explains the optimization focused on Ultra-Low Power MCU and shown Montgomery multiplication and squaring. It describes in detail the procedure of calculation and described why is his calculation faster than conventional modular multiplication and exponentiation. The appendix include installation instructions for the libraries BigDigits, GMP and OpenSSL in Visual Studio 2010.

Automatic people counting
Szalbot, Michal ; Mišurec, Jiří (referee) ; Koutný, Martin (advisor)
The main subject of this bachelor thesis is utilization of optical sensors for people vehicle counting. This types of sensors were selected - optical barrier, passive infrared sensor, active reflective sensor and ultrasonic sensor for people vehicle counting. The tasks and used sensors are described in introduction. The selected applications available on the market and description of their function are described there too. The solution describes individual type of sensors, their function, used involvement in tests and tests results. The conclusion contains summary of knowledge of sensors, their possibilities and other possible solutions.

Analysis and design of extinguisher fastening in passanger vehicles
Koutný, Martin ; Zdražil, Květoslav (referee) ; Hrubý, Jaroslav (advisor)
This thesis looks into current requirements of having fire extinguisher in a car in both the Czech Republic and other countries. At first, there is an evaluation of current ways of mounting fire extinguishers in cars, as well as evaluation of various requirements concering safety and ergonomy of mounting fire extinguisher in a car and also what are the hazards of having unattached fire extihnguisher in the passenger compartment. The objective of this thesis is to desing and test a fire extinguisher holder which would fullfil these requirements and which will not require changes in the body of the vehicle. The final part of this thesis deals with evaluating of possibilities of mounting this holder into several types of vehicles.

Web Application for Monitoring of Elecric Energy Consumption
Režný, Jan ; Koutný, Martin (referee) ; Šimek, Milan (advisor)
Bachelor thesis called „Web Application for Monitoring of Elecric Energy Consumption“ focuses on receiving, processing and visualization of measured values from wireless sensor network, which is measuring the consumption of electrical devices. The aim is to create a applications for data receiving and proccessing and application which can manage connected power meters, user-defined devices and its association, export measured data and display reports, graphs and statistics obtained from these measured values.

Monitoring of GSM network
Trávníček, Tomáš ; Krajsa, Ondřej (referee) ; Koutný, Martin (advisor)
This master’s thesis is focused on problems of monitoring GSM network using a mobile phone. Problems are analyzed on a theoretic basis with a description of available network parameters. Then the thesis offers a description of existing application environments providing a user with given data about the network. The main part of this work describes a development of application compiling queue data from mobile network and GPS, and creates output data illustrating signal strength in selected areas. The work also includes extensive measuring in select areas together with an evaluation of the processed data.

Analysis of GSM network, using open source SW radio
Kilian, Petr ; Koutný, Martin (referee) ; Šilhavý, Pavel (advisor)
This master thesis is focused on analysis and creation of GSM network, using open-source projects. For such creation is used software defined radio – in this thesis kit USRP1 which uses OpenBTS with GNURadio. As a switchboard is used PBX Asterisk and for testing GSM network was used OsmocomBB (on Motorola C123) and Airprobe (on Nokia 3310) projects. Installation and implementation are part of this thesis. In thesis have been also created two scripts for simplify of the work with projects and one laboratory task.

Network load generators
Kubík, Pavel ; Koutný, Martin (referee) ; Pelka, Tomáš (advisor)
The aim is to create, test and describe the network load generator for server-client connection type. It´s used language C++ under Linux. It was also used socket and multithreading programming. Load on the server is done by sending HTTP requests. The load generator have different adjustable parameters and displays the test statistics. In this work is described mechanisms wich are used, by the application, to load. Testing was done on one server with a different size of the target file.

Communication unit for intelligent home appliances
Čičmanský, Tomáš ; Koutný, Martin (referee) ; Mišurec, Jiří (advisor)
Bachelor’s thesis is devoted to clarify the issue of PLC. The main task is to gather the necessary theoretical knowledge about PLC, which will be then used to design functional narrowband modem. It will interact with and manage devices connected to the network and use appliances, sensors and other devices in the so called smart house. This project is made particularly with regard to price, availability and final device parameters.
