Message Encryption over Text Messengers for Android
Balvín, David ; Burget, Radek (referee) ; Kolář, Dušan (advisor)
The main purpose of this thesis is to design and implement an application that would handle encrypted communication using several protocols or existing applications. The application is able to handle automatic encryption using a symetric-key algorithm for sending messages and decryption on demand for receiving/reading messages. It also supports asymetric exchange of keys for symetric encryption. A simple user interface is also created for this application, taking ideas from default SMS application for Android and popular Messenger a Whatsapp.

Communication devices over GSM/GPRS
Prečan, David ; Růčka, Lukáš (referee) ; Herman, Ivo (advisor)
This master thesis deals with a data remote transmission by means of SMS and GPRS technology. The overview of current solutions is presented and then a remote temperature measurement and a data transmission employing a communication module GSM/GPRS TM1 through GSM network using GPRS technology is described. As a response to an impulse, the communication module sends SMS. The technical solution is described in details including HW and SW design of the data transfer and processing equipment using a ATmega 162 microprocessor. This equipment communicates with a server (PC), which displays the measured temperature. A prototype which was used for a validation of the design is also described.

Intelligent monitoring device
Nosek, Zdeněk ; Šteffan, Pavel (referee) ; Kadlec, Jaroslav (advisor)
This master thesis discusses design and realization of a security device for vehicles. This device can determine its actual location, discover unauthorized trespass and send information about this to a distant master system too. This distant master system can show the exact position of the security device on a map. The hardware and software for this security device and the software for the master system are described in this paper.

The use of information technology to support safety management in aviation
Poloch, Gabriel ; Hammer, Jaromír (referee) ; Šplíchal, Miroslav (advisor)
The purpose of the Thesis is to acquaint reader with Safety management system in the aviation. In the beggining Thesis describes the begining of safety management, why was the system created and how it developed in the past. The main part of the Thesis is focused on identification of software tools for easier implementation of Safety management system in the training organizations. Another part of the Thesis is focused on aplication of selected software tools on small training organization (ATO) with complex disposition.

Automatic Template Pattern Recognition
Kovařík, David ; Lengál, Ondřej (referee) ; Šimková, Hana (advisor)
Spam se typicky nevyskytuje ve formě samostatných zpráv, ale často bývá sdružován do takzvaných kampaní. Ty bývají automaticky generovány pomocí šablon. Díky tomu jsou jednotlivé zprávy sémanticky, ale ne syntakticky, ekvivalentní. Cílem práce je navrhnout algoritmus schopný z množiny zpráv jedné kampaně zpětně extrahovat šablonu, ze které tyto zprávy byly generovány. Práce se zaměřuje na spam v SMS komunikaci, ale navržené postupy jsou dostatečně obecné pro širší použití. Algoritmus je postaven na metodě zarovnávání dvou sekvencí, používané v bioinformatice pro nalezení podobných oblastí proteinových řetězců. Výstupem je regulární výraz popisující šablonu dané kampaně. Součástí řešení je také nástroj pro vizualizaci šablony pomocí HTML.Řešení bylo ověřeno na přibližně třech stovkách skutečných kampaní z celého světa. V naprosté většině případů je poskytnutý výsledek postačující pro identifikaci kampaně.

Design of measurement robotized workcell
Tvardek, Michal ; Sláma, Josef (referee) ; Knoflíček, Radek (advisor)
This master's thesis focuses on the use of the Renishaw's Equator gauging system in cooperation with the industrial robot. The target is to design the robotized workcell which contains these two products. Robot acts as a manipulator for inserting and sorting out the workpieces into the "good" and "bad" pallets according to measured results from the Equator. Equator uses a parallel kinematics and probing system which is normally used on coordinate measuring machines. Therefore there is the introduction to the parallel and serial kinematic structures, to the problems of the coordinate measuring machines in the first part of this thesis. It was made a separation of the probing systems into a few basic categories, description of the typical representatives of these categories and of the other important accessories of the coordinate measuring machines, too. The second part of the thesis contains a description of the Equator gauging system, the industrial robot which I used and their accessories. In this part is mentioned a few examples of measurement automation in industry practice, too. The third part devotes to the design of the robotized workcell and contains all the important requirements for the realization.

Automatic detector of vehicle road accicents
Žurek, Jan ; Morský, Ondřej (referee) ; Dostál, Otto (advisor)
This master‘s thesis treat of car safety. It includes an introduction into already existing active and passive safety systems and briefly describes their basic principles. It also includes a description of basic principles of car electronic systems. It will acquaint us also with elementary calculations in the area of car crashing into a solid obstacle. On base of this information was developed and consequently realized development module of an automatic car accident alarm that transfers information using SMS messages to a cell phone. The message contains date, time and GPS coordinates of the accident and acceleration sensor readings in three axes.

SMS Application for JavaME Platform
Růčka, Lukáš ; Burget, Radim (referee) ; Kovář, Petr (advisor)
The aim of this diploma thesis is to study the potential of Java ME platform for receiving and sending of SMS and to utilize obtained information subsequently in implementation of an application for this platform. The first part of the diploma thesis aims at explaining general terms of the Java language and its basic features. The next part deals with specific properties of the Java ME platform and properties of devices that support this platform. A design of the Java ME application based on theoretical knowledge is created then. This application has to be able to receive, process, store and send SMS and communicate with the server application based on the Java SE platform. The created Java ME application serves as an automated SMS voting server, which can be used in mobile devices that support the Java ME platform and can be remote-controlled via Internet from the Java SE platform application. The final chapter presents the results and conclusions of testing of the created application on real mobile devices.

Notification Filter for Android
Vlkovič, Vladimír ; Zachariáš, Michal (referee) ; Szentandrási, István (advisor)
The goal of this thesis is to develop an application which can block incoming calls, text messages and notifications on Android based mobile devices. The thesis contains a description of common theory, three designs of user interface from which two of them were implemented as applications. These two applications use different approaches to the filtering. The first uses the black list approach, the other the white list approach. The applications were successfully tested by twenty users. The average score in the questionaires was six out of seven which is considered a great success.
