Electrodynamic forces acting on moving contact of electrical apparatus
Šic, Pavel ; Valenta, Jiří (referee) ; Bušov, Bohuslav (advisor)
This master’s thesis is focused on calculation, simulation and experimental verification of electrodynamic forces acting upon movable contact piece of MCCB and experimental current carrying path. A short description of low voltage circuit breakers is briefly discussed in first chapter. Second chapter is focused upon contact system analysis of particular MCCB with thermomagnetic trigger. A hardness of contact materials is briefly described. A detailed analytical calculations were used to determine electrodynamic forces in MCCB. A FEM simulation in ANSYS Maxwell was carried out for comparison with analytical results. An experimental apparatus was designed and built for verification of constriction repulsion force, so called Holm’s force. A series of measurements is subsequently performed on proposed apparatus and results are compared with results from previous chapters.

Mobile Application for New Students at the FIT BUT
Muráň, Michal ; Zachariáš, Michal (referee) ; Kajan, Rudolf (advisor)
The study deals with the creation of mobile application for Windows Mobile 7 operating system, which serves to simplify the study to new students at the faculty of the FIT BUT. The theoretical section deals with the acquirement of feedback from students suggesting particular elements of application. On grounds of obtained information, proposal of content and boundaries has been made. The practical section deals with the implementation of the application´s functionality.

Advanced Synchronization of Contacts and Calendar with Google Services
Dohnal, Matěj ; Zelený, Jan (referee) ; Očenášek, Pavel (advisor)
The purpose of this barchelor’s thesis is to sum up the knowledge of personal data synchronization between a desktop application and the Google services. The main goal is to design and implement own application which would perform advanced synchronization of personal data. The design should be based on knowledge from the first step and also on deep analysis of existing solutions. Last part of the thesis describes testing of the implemented application and discussion of aproached goals and following development of the application.

Transfer and Backup of Text Messages (SMS)
Černý, František ; Křivka, Zbyněk (referee) ; Kolář, Dušan (advisor)
The subject of this bachelor thesis are two cooperating applications to backup, restore and to view SMS messages. The first of the implemented applications, designed for the Android operating system can backup and restore SMS messages using XML file. The application also enables synchronization of the imported file with existing short text messages. The second application is used as an extension for Thunderbird email client. This extension lets you view imported text messages, synchronize your saved short text messages with contacts in SMS threads, search in saved file and synchronize existing SMS information with newly imported file. The extension also allows exporting a file with SMS messages and uses this exported file in application for Android operating system.

Static analysis of one joint of timber structure
Sedlák, Petr ; Gratza, Roman (referee) ; Kytýr, Jiří (advisor)
This diploma thesis deals with the numerical modeling of the nail joint of the timber roof structure and it is based on the already realized physical experiment. Totally twelve various solutions, where the isotropic and ortotropic characteristics of the spruce timber and steel components change, have been created. The final values of the joint shift obtained by using of the numerical modeling are compared with results of physical experiment. Program system ANSYS is used.

Analysis of project OHK Brno for business subject in region
Majer, Petr ; MBA, Libor Kejda, (referee) ; Mandelík, Petr (advisor)
This thesis seeks to analyze the impact of a range of projects of Chamber of Commerce Brno on the entrepreneurs from the respective region. The thesis describes the structure and the overall operation of the Chamber of Commerce Brno as well as its several projects. In order to evaluate, there are three marketing researches that need to be taken into a consideration. Those marketing researches had been realised during the period of 2005 – 2007. Baring the results risen from the abovementioned marketing researchs in mind, the created situation has been assessed, and based on the personal experience the recommendations dedicated to the management have been created.

Trees Have the Power
Mikušková, Nina ; Fajnor, Richard (referee) ; Kovářová, Marta (advisor)
The project "Trees Have The Power" is being developed since 2013 and revolves around the strength of interpersonal connections experienced throughout our lives. It points out the reality, that we all create our own micro-cosmos around us, shaped and expanded by every new person we meet. First phase of the project involved exhibition of a tree within a gallery, which served as a metaphor of an ever expanding organism. For the second phase an online social platform was developed, to map out and connect my personal contacts. The third outcome offers space to present the "tree". By involving people from my own personal tree of connections, we are creating lectures, interactive events, concerts, film screenings, and discussions focused on multiple aspects of life. The aim is both to test the skills and initiative of a specific community as a driving force in sharing and accumulating knowledge and experience; and at the same time to demonstrate the magnitude of impact of such activity. This unorthodox framework of encounter offers opportunity to generate new perspectives within the community, and enrich the audience.
