Modular Power Supply for Formula Student
Ščípa, Samuel ; Bohrn, Marek (referee) ; Pavlík, Michal (advisor)
This bachelor thesis is focused on the theoretical analysis and design of switching power supply with galvanic isolation. The implementation of the design is in the form of the power and control part of the modular power supply. The device parameters are suited for the needs and requirements of the development department of the electric student formula. Design configuration achieves a maximum output voltage of 1000 V and a current of 100 mA, which are user-adjustable.

Asterisk VoIP private branch exchange and its distributions
Melichar, Ondřej ; Komosný, Dan (referee) ; Papež, Nikola (advisor)
This master’s thesis delves into the possibilities of the open-source Private Branch Exchange Asterisk, elaborates on its features and compares it with several other distros. The term SIP stack is explained here with the mention of two of its representatives. Further in the thesis, the security risks of the VoIP technology are explained, and specific attacks are described and then realized. As a part of the testing process, the possibilities of a custom module and its following implementation are explored, as well as the portability between the individual distros and its proper functioning.

Management and Monitoring System for Computer Lab
Kudláček, Marek ; Zeman, Kryštof (referee) ; Mašek, Pavel (advisor)
This master's thesis deals with a system for PC mass management and monitoring. There is a brief description of Puppet, Chef and Ansible, which are tools enabling this functionality. The overall system issues are solved by Ansible. This thesis also includes a script created for a classroom’s remote management according to a beforehand fixed assignment. The system enables remote installation and configuration of applications, creation of users, editing the files, update of the system and many more. A web application was created for this system. Through this application, the system can be controlled via web browser, both from local and public network. Practical examples of the issue dealt with is also part of the thesis.

Wireless 802.11 IP Networks and their models in the OMNeT++ simulation tool
Jakúbek, Peter ; Burda, Karel (referee) ; Růčka, Lukáš (advisor)
The bachelor work concentrates on familiarization with the standard IEEE 802.11. The work summarises the advantages, disadvantages, history and grouping of this standard according to norms. The great attention is paid to a user’s familiarization with the stimulating tool OMNeT++ and its extension Inet Framework. This extension helps to amplify the simulator for a supporting modelling of wireless nets. It supports models of a few protocols such as IP, UDP/TCP, Ethernet, PPP, IPV6, OSPF, RIP, and MPLS. It includes already programmed API modules from which is possible to create easily a wireless IP net.Programmes needed for a proper functioning of the OMNeT++ are described in corresponding paragraphs. A part of work deals with an installation and setting of programmes for accurate functioning of a compiler surrounding. Our work analyzes possibilities and manners of simulation of wireless IP nets which helps to create basic simulation model represented by standard 802.11. There are also included laboratory works in our bachelor work, which includes theoretical introduction to studied issues. Tasks are concentrated on ad-hoc and infrastructure mode. These tasks comprise of theory of problematic, detailed instructions for creating together with explanations, processed results and output of simulation
