Application for Data Presentation and Modification in Mobile Devices
Kučera, Pavel ; Ryšavý, Ondřej (referee) ; Trchalík, Roman (advisor)
This thesis is aimed to study the possibility of usage of mobile devices in the sphere of automation. One automation company needed to have in hand some PDA-based tool for a remote control of the technological process. There is analysis of ability of contemporary portable devices to run a application software. According to the specified requirements there is designed and implemented the client-server system based on the VNC technology. The server is a Linux-based PC server implemented using Xinetd daemon and the Xvnc. The two standard VNC clients were made. A free software available under the GPL license was modified to implement them. One runs on Windows Mobile operating system and the other one is a Java MIDlet.

MySQL and MS SQL Database Synchronization
Šimanovský, Filip ; Grégr, Matěj (referee) ; Trchalík, Roman (advisor)
This thesis describes the synchronization of MySQL and MS SQL databases . It explores and describes differences between these two database servers and further designs and implements alghorithms for their safety and economicaly favourable synchronization . Designed methods are implemented in a console application afterwards . Two case studies are used as an illustrative of its work . The result of this thesis is a manual on how to successfully convert MySQL database to MS SQL database (and vice versa ) and the convert application itself .

AOS: Tool for Graph Analysis
Siebert, Martin ; Holkovič, Martin (referee) ; Trchalík, Roman (advisor)
This Bachelor's thesis is focused mainly on design and implementation of a tool, that analyses price graphs. One of the main requirements of the design is modifiability and maintainability of source code. This goal is achieved with the MVC architecture and by creating independent system components. The application takes care of collecting the data from the trading platform, performs the calculation based on the requirements and displays the information in the graph. For each module, the calculation is being done independently, whereas the modules can form multiple sequences of different lengths. In this Bachelor's thesis, there are five analytical modules implemented and two sample case studies created.

Analysis of Selected Security Protocols
Malecký, Marek ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
The subject of this thesis is to study available security protocols and tools for their verification. The first part is devoted to briefly describe the concepts related to the area of security protocols and verification logics. The second part directly lists various protocols, along with attacks and errors found in design. Next chapter describes the most important tools for automatic analysis of security protocols in more detail. The main part deals with verification of security protocols selected in the chosen tool called Scyther. In conclusion, examples of multiprotocol attacks along with a summary table are displayed.

Application for Payment Terminals Control and Remote Management
Gajdůšek, František ; Trchalík, Roman (referee) ; Kreslíková, Jitka (advisor)
The goal of this thesis is to create control software for stand-alone payment machines. The purpose of this software is minimize maintenance cost and usability as much as possible. Description of technologies and protocols used in implementation are in the text. Next, there is process of work beginning with analysis, continues with design, construction, testing and installation manual. Projekt status and product utilization at the end of project is in chapter about evaluation.

Specification Languages and Tools for Analysis and Verification of Security Protocols
Ptáček, Michal ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
This diploma thesis is focused on the analysis of security tools, which are commonly used for automatic verification of security protocols mainly. These security protocols are used for creation of private communication channells in insecured networks. Security will never be perfect, so finding of weaknesses in security protocols is always necessary and we need to improve these protocols. In this diploma thesis I have focused on looking for various verification tools on Internet. Subsequently, I have described each tool in this thesis, in way that each reader can easily find out, which tool is for him useful and which is not. I have summarized main benefits and drawbacks of each tool at the end of his description.

Application for Tracking Devices for Windows Phone OS
Pupák, Juraj ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
This application deals with recording of position about phone devices with help of system GPS. The application is implemented for platform Windows Phone 7.5. The Application allows to create profiles, which are evaluated with recorded positions. The evaluation is made through 2 points with Haversine formula. The theoretical part of thesis deals with technologies and GPS system, the practical part deals with design and implementation.

Linux OS Monitoring
Korček, Juraj ; Očenášek, Pavel (referee) ; Trchalík, Roman (advisor)
The aim of this bachelor's thesis is design and implementation of monitoring tool for GNU/Linux operating systems. This program monitors logs created by system, system load and computer resources. It notifies system administrator in case of high system load, abnormal behavior or when an error occurs. The resulting product is especially aimed for system administrators of GNU/Linux, whose work will be simplified due to this software utility, which sends notification of only important system changes. It is implemented in scripting language Python and divided into smaller independent scripts for easy implementation of new scripts in the future. This programming language was chosen to ensure operation among all GNU/Linux distributions.

Tasks Board Optical Recognition
Sznapka, Jakub ; Trchalík, Roman (referee) ; Kreslíková, Jitka (advisor)
The master's thesis deals with the optical recognition of the tasks board in the agile environment. Based on theoretical knowledge about the agile project management, the concept of the task board is introduced. Possible representations of this agile tool are discussed, as well as their advantages and disadvantages. In connection with the optical recognition of the objects, follows the theoretical part dealing with barcodes, their structure and methods of detection and decoding. Based on these facts, the application design is reflecting all the needs specified by the company Siemens CT DC which is the contracting authority of the project. Implemented solution used for synchronization between the physical and virtual task board is able to detect the task cards with reliability about 95 % and allows the full synchronization of the task board during the four cycles. Deployment in the software development team and using the fully automated mode brings approximately five times quicker synchronization than it was before. In a case of semi-automated mode, it is about three times faster than before.

Using Near-Field Communication (NFC) to Improve Messaging Privacy on Android OS
Karmazín, Jaromír ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
V této práci vytváříme jednoduchý systém pro rychlou textovou komunikaci (IM), který využívá technologii Near-Field Communication (NFC) ke zlepšení bezpečnosti a soukromí. V první části zkoumáme samotnou technologii NFC. Poté se věnujeme možnostem NFC v operačním systému Android pro chytrá mobilní zařízení a také existujícím aplikacím, které tyto možnosti využívají. Rovněž zkoumáme nejmodernější přístup k bezpečnému IM, zejména Signal Protocol a jeho open-source implementaci pro Android. Dále pak navrhujeme IM systém, který používá Signal Protocol pro šifrování zpráv a NFC pro výměnu kryptografického materiálu, aniž by vyžadoval použití telefonních čísel nebo důvěryhodnou třetí stranu. Nakonec předkládáme vzorovou implementaci klientské i serverové aplikace a zhodnocení vlastností tohoto systému z hlediska soukromí a bezpečí.
