Laboratory exercises in OPNET environmentfor Communication technolgies course
Kasper, Robin ; Hošek, Jiří (referee) ; Jeřábek, Jan (advisor)
This master’s thesis deals with the design of laboratory exercises for the Communication Technologies course that is included in the second year of bachelor’s degree in Teleinformatics. This course represents first introduction of students with network protocols and technologies, therefore, the thesis deals with just the basic physical technologies, routing protocols and transport layer protocols. The introductory part of the thesis is devoted to theoretical knowledge to particular tasks. For the design of laboratory exercises is used OPNET environment, concretely its unpaid version IT Guru Academic Edition 9.1. The first task is focused on the differences in two basic transport protocols Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). The second task is orientated on the differences in the transmission network parameters using wireless networks and Ethernet technologies. In the third task the routing protocols Routing Information Protocol (RIP) a Open Shortest Path First (OSPF) are compared. These are protocols of a group Interior Gateway Protocol (IGP) that are characterized by the usage within a single autonomous system. The last exercise is aimed at Asynchronous Transfer Mode (ATM) and Frame Relay technologies, which are technologies used mainly in networks Wide Area Network (WAN). All devised exercises are accompanied by detailed instructions for students including supplementary questions and tasks leading to individual work and reflection. The thesis includes model solutions to these four exercises and CD where are inserted all programs source codes.

Measurement of passive frequency crossovers for loudspeaker systems
Holínský, Jan ; Hanák, Pavel (referee) ; Balík, Miroslav (advisor)
The content of the master´s thesis is to approach the issue of measuring the characteristics of passive frequency crossover. The work describes individual types of measured characteristics and their possibility of measurement. Then the work describes design of modules for measurement characteristics of passive frequency crossover (shunt, resistive load and amplifier). These modules were made and tested for its functions. For the amplifier is then made a second design for fulfilment requirements. The second version isn’t made in this work. At the end of the work was prepared the theoretical part of the laboratory task: Measurement of characteristics of passive frequency crossover, including protocol.

Laboratory exercises in Riverbed Modeler simulation environment
Lojek, Stanislav ; Bečková, Zuzana (referee) ; Langhammer, Lukáš (advisor)
This semestral thesis deals with the creation of a laboratory exercise for the course of Communication Technology. This course is designed for Teleinformatics in bachelor's degree program and should provide students with basic knowledge of network protocols and technologies. For this reason, the thesis deals with basic transport protocols, protocols for transmission via backbone networks and network layer protocols. The introductory part introduces the OPNET design environment, more precisely its free version of Riverbed Modeler Academic Edition 17.5, where the design of the laboratory exercises is done. The second part is a necessary theory to the exercises. The lab exercise is focused on differences in TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) protocols. The second laboratory exercises is focused on technologies for transmission mainly on WAN (Wide Area Network) namely ATM (Asynchronous Transfer Mode) and Frame Relay. The last proposed exercises deals with the two most prominent Internet protocols that are used for communications IPv4 (Internet Protocol version 4) and IPv6 (Internet Protocol version 6) protocols. Guides for students have been created for this task, and at the end of each part, the complementary tasks and questions are given to students in oder to test the gained knowledge of the discussed issues.

Advanced Utilization of Network Analyzers
Novák, Přemek ; Polívka, Michal (referee) ; Škorpil, Vladislav (advisor)
This bachelor´s thesis consists of description of the laboratory network Cisco and any of its components. Furthermore, the possibility of network analysis according to the standards RFC 2544 and EtherSAM and description of the measurement using analyzer Vepal TX300, Fluke NTS II and Sunlite E1 used in lab reports. In the first task, the characteristics of network elements are analyzing. In the second task, parameters of Cisco network are examined and the third task is focused on the E1 frame.

Gloves with motion sensors
Findejsová, Anna ; Cicková, Pavlína (referee) ; Janoušek, Oto (advisor)
Bachelors thesis deals with design and realization of a glove with flex sensors. This thesis summarizes problematics of resistive sensors, describes their principles and using. Then deals with brief upper limb anatomy and degrees of freedom. Theoretical base is stated in chapter one and then used in chapters two, three and four, that describe the design and realization of hardware and software. The principle is based on capturing the flection of the fingers by using flex sensors connected to the Arduino development board and their visualization. The output of this thesis is a laboratory task for teaching senzorics, which is designed for using one flex sensor.

Use of a programmable logic controller in teaching process
Malý, Jan ; Knobloch, Jan (referee) ; Červinka, Dalibor (advisor)
Bachelor thesis is divided into four parts. First part concentrates on programming languages used for programming a PLC. These are divided into graphical and text languages. Graphical languages consist of ladder diagram and function block diagram. Text languages are Structured text and instruction list. Each of these languages are described in subchapters. Second part deals with description of three laboratory tasks. The last part contains pictures a information about laboratory task’s made equipment.

Side channel attacks on chip cards
Matějka, Jiří ; Morský, Ondřej (referee) ; Martinásek, Zdeněk (advisor)
This master thesis deals about the issues of chip cards’ side channels. Side channels are new method in cryptanalysis. Unlike classical cryptanalysis, which looks for weaknesses of mathematical structure of algorithms, side channel’s analysis use weaknesses of physical implementation of these algorithms. First part describes chip cards, their usage a security. There is mentioned the issue of cryptographic algorithms and their implementation on smart cards. There are described well-known side channels and examples of their abuse. Practical part of this thesis is focused on a proposal of a laboratory task, which demonstrates power-based side channel attack on smart card. There is designed laboratory workplace for this task, software for measurement and analysis is implemented in development tool LabVIEW. In the last part is this attack realized, the target of this attack is a standard SIM card.

Vaněk, Jiří ; Kubánková, Anna (referee) ; Novotný, Vít (advisor)
The main objective of this thesis is to get acquainted with the field of designing professional data networks and with typical network service required at these networks. A basic description of network hierarchy and of network elements is part of this thesis. At the same time, individual network services and their usage are defined. At the latter part of the thesis there is a suggestion of design creation steps and of service implementation. Further on, the thesis describes a real design of a laboratory task and it’s practical implementation. Detailed guidelines how to complete a laboratory task are part of this thesis.
