Synthetic immittance dipoles using active current elements
Mráka, Michal ; Jeřábek, Jan (referee) ; Koton, Jaroslav (advisor)
This master thesis discusses the design of Synthetic immittance dipoles using active current elements. The introduction presents aktive current elemetns MO-CF and DACA as buildings blocks for analog filters that are able to process signals with frequencies up to ten megahertz. Methods of synthetic elements using active current elements design is described in this thesis.Is resulted from full addmitances net which contains one active current element Subsequently there are designed various types of frequency filters working in current mode. The functionality of designed filters was verified by computer simulation. Selected designed filter were practically verified with commercially available elelments and active element MO-CF. Measurements in the frequency domain were carried on. On all of types of filters are made sensitivity analysis.

Communiacation software for terminal clients of a Linux server
Hanák, Karel ; Jeřábek, Jan (referee) ; Jelínek, Mojmír (advisor)
The thesis contains a proposal and implementation of an environment convenient for operation of network client applications which use common terminals. It also consists of implemented examples where the way of their usage is presented. The centralized way of communication is the basis. The approach is used also for the possibility of their joining with managing subsystems, i.e. unlimited ways of regulation of systems for real estate management, access to devices, user authority access to access data points to the devices. The environment is based on operation system Linux and database MySQL. Their realization is supposed on a server, in the network environment. This relates also to the overall security policy and this work also focused on social treatment of clients possibilities.

Security of wireless computer networks IEEE 802.11
Škodák, Jaroslav ; Jeřábek, Jan (referee) ; Koutný, Martin (advisor)
This work describes available and used standards, protocols and mechanisms used to secure IEEE 802.11 wireless networks. In the next section are listed vulnerabilities and possible attacks against different types of security. The principles of individual attacks on authentication, WEP security and WPA/WPA2 personal mode are described and realized using various software especially linux program aircrack-ng. Password for WEP security is obtained by passive eavesdropping data, using ARP replay injection and by creating own frames. The last two methods are used to generate traffic on the network, which is captured and then used to derive the WEP password. By injecting ARP frames, password was found in the number 60 000 captured frames and about 180 000 frames of data was needed for passive method. Decryption of WEP frame was done by fragment and KoreK chopchop attacks. This decrypted frame could be used to create fake frames and obtain WEP password. Brute force attack is realized for security WPA (WPA2) personal mode (often due to lack of strong password) by comparing password (passphrase) from password list. Speed of comparing is about 200 passwords/s.

Special knowledge and skills of rescue workers and its application in Integrated Rescue System
JEŘÁBEK, Jan
This thesis deals with the topic of rescue from free depth and from height. The aim of the thesis is to determine the level of special training of medical rescue workers who operate in the South Bohemian region in the field of rescue from free depth and from height. The first, theoretical part of the thesis covers the topic of rope techniques and rescue from free depth and from height. First, I defined basic material used in rope techniques and during rescue work from depth and from height, then also knot and knot techniques and finally I outline basic skills and methods used during rescue work from free depth and from height. The second, practical part of the thesis presents results of quantitative research. The hypothesis stated assumes that emergency service workers lack professional training in the field of rescue of individuals from free depth and from height. The research sample comprised randomly selected paramedics who work in Emergency Medical Service in South Bohemia in Tábor, České Budějovice, Český Krumlov, Prachatice, Strakonice and Písek. To obtain necessary data, the method of quantitative research, interview technique through a questionnaire was used. Collected data were evaluated and compared to stated hypothesis using contingency tables and graphs. The questionnaire consisted of 24 closed questions. The first half of the questionnaire covered identification questions. The second half of the questionnaire comprised questions to test special knowledge of material and work techniques in the field of rescue from free depth and from height and was designed to determine the level of expertise and preparedness to use rope techniques. The results of the research show that paramedics who work in Emergency medical services in South Bohemia have relatively sufficient professional training in the field of rescue from free depth and height. The hypothesis was not confirmed.
