Sensor devices emulator for industrial networks
Malček, Ladislav ; Fujdiak, Radek (referee) ; Blažek, Petr (advisor)
The task of bachelor thesis is design of sensor devices emulator for industrial networks. Subject of the first part is description, safety and control of electric network. Afterwards the current and voltage sensors and merging units for analysis of data are presented, followed by description of the used microcontroller, and all the individual components of simulator. In the next part the design of circuits for voltage, current and binary outputs is presented. The third part of thesis are designs of control terminal and web interface for setting of simulated values by user. After physical realization of emulator, it was tested on a control device. The last part of the thesis are results of testing.

A Tool for Testing of DPWS-Based Web-Services
Malášek, Vojtěch ; Očenášek, Pavel (referee) ; Rychlý, Marek (advisor)
The aim of this thesis is a design and implementation of tool for testing and monitoring of DPWS-based web-services. At first the thesis contains explanations of basic concepts related to Web Services, DPWS and used design patterns. Further the thesis contains the design and tool implementation description. The tool provides a client-side services implemented by Windows Communication Foundation, which communicates via the DPWS-based service. The service is implemented using .NET Micro Framework and can be run in the emulator in the integrated development environment. Obtained results and options for further extensions are mentioned in conclusion.

Configuration and diagnostics for Smart Grid
Hrbek, Martin ; Šťastný, Ladislav (referee) ; Franek, Lešek (advisor)
This thesis designs a solution for configuration and diagnostics for the Smart Grid. It creates use case diagram for configuration and diagnostics and designs individual software modules of the system. The thesis informs a developer about suitable devices for configuration and diagnostics for the Smart Grid, especially about rugged handhelds. The thesis chooses suitable software tools for development of designed modules and contains recommendations for developers, how to use this tools. The realization of one of the designed modules verifies the correctness of the designed solutions and approaches.

Java Byte Code Emulator Suitable for Malware Detection and Analysis
Kubernát, Tomáš ; Rogalewicz, Adam (referee) ; Drahanský, Martin (advisor)
The goal of this thesis is to create a virtual machine that emulates a running programs written in Java programing language, which would be suitable for malware analysis and detection. The emulator is able to detect arguments of exploitable methods from Java standard classes, the order of calling these exploitable methods and also execution the test application. Overall functionality was tested on appropriate examples in which held its own measurements. At the end of the paper we describe testing of the emulator, which also contains tables and graphs for better results visualization.

Modeling the Basic Principles of Communication Technologies
Ruiner, Michal ; Koláčková, Aneta (referee) ; Hošek, Jiří (advisor)
This bachelor thesis deals with the design of 5 laboratory tutorials where the basic principles of communication technologies are modelled. A reader is apprised with the available software first for the simulation of network technologies. The simulators and emulators are compared. Packet Tracer, a software developed by the Cisco company, is chosen for the lab exercises and Wireshark, a network protocol analyzer, for the traffic capturing on a local PC. Then the reference model ISO/OSI is described for the basic introduction to the principle of network communication. The Chapter 3 explains the basic problematics of network paths searching, the routing table contents and division according to the type of routing and routing protocols groups. In the next chapter, particular communication protocols used in the labs are analyzed in detail. Final part briefly describes the implementation of all laboratory exercises. Laboratory tutorials are provided in the appendices.

Hardware MISO Emulator for Fading Channels
Rez, Jan ; Pítra,, Kamil (referee) ; Šebesta, Jiří (advisor)
This thesis is devoted to study the possibility of solving a hardware MISO emulator for fading channels and design of experimental device. The theoretical part starts with the theory of propagation of electromagnetic waves in a different types of environment, follows the principles and phenomena describing the radiocommunication channels and gradually gets up to specific channel models used for planning radio links. The actual design study of emulator is based on theoretical knowledge mentioned in this thesis. The basic principle of each channel model and thus so the emulator for fading channels is Tapped Delay Line model. From the point of view of the peripheral emulator solutions are designed with two topology circuits, parallel and serial-parallel. Emulator control method, mechanical arrangement, selection of topology circuit, components selection, desing of the PCB and software design is also analyzed. The results of this thesis is prototype production of experimental device and final discussion about achieved requirements and tasks.
