Simulation of data transmission latency between nodes in IP networks
Balej, Jiří ; Molnár, Karol (referee) ; Komosný, Dan (advisor)
This master thesis is focused on the delays incurred in data transmitting over IP networks. The top of the paper is devoted to points, where delay is invoked and causes of the latency. For individual sources of delay are are described the parameters that affect the usual size of latency. The next section describes the types of networks and their typical delay. In the paper are also discussed tools for measuring delay and determining the number of intermediate devices. The thesis contains results of measurements delay time in the real network. For these results are listed conclusions about the delay for one intermediate device. There is also said general ratio of crow-fly distance and calculated distance. The last part deals the simulation of delay in the NS2 program. The results of thesis are scripts that shows the relation of delay and the number of switches, routers, and the length of the path.

Automatic measurement of the motor vehicles distance.
Juřica, Lukáš ; Chmelař, Milan (referee) ; Říčný, Václav (advisor)
This work deals with evaluation of equipment used for non-contact measurement of distance between vehicles. First are discussed various principles of measuring and after the selection of the most appropriate solution is proposed a detailed block diagram of modulation, demodulation and evaluation of the whole system and its mathematical description. Another part is devoted to describing the activities of the microprocessor controller, with which is controlled evaluation part and to the control program. It also analyzes the maximal attainable accuracy of measurement and the errors that affect it. The last part includes a circuit design and simulation of selected functional block, which is a coincidence /quadrature/ detector and construction documents for evaluation and demodulation part of the measurement instrument.

Localization system making use of GPS and GSM
Klozar, Lukáš ; Pust, Radim (referee) ; Šebela, Radek (advisor)
Aim of this master´s project is to analyse localization possibilities in GSM and GPS wireless networks. Choise of proper module and design location device for both GPS and GSM networks. Design and construction of system, which is able to designate it´s positron, using both GPS and GSM networks. The location informations, are send to Internet server, using GPRS system. Localization techniques in both wireless network are described. The system which is able to get position information was designed and constructed. The module´s driving software and the software, which process the localization informations and controls the database storing process, was designed.

FAMILY HOUSE WITH THE SURGERY GENERAL PRACTITIONER
Volf, Josef ; Vlach, František (referee) ; Štěpánek, Ladislav (advisor)
The theme of bachelor´s thesis is new-building family house with the surgery general practitioner. The residential area is divided for the two separate housing units. One of the apartments is duplex. The Surgery is wheelchair accessible. It has a separate entrance form the north side. The building is set in sloping terrain. It has three floors, it is partly basement and 3NP is solved in the attic. It is a brick building, which is the system POROTHERM with a combination of BTB fittings in the basement. Roofing is solved by a combination gabled and rack roof with a pitch 35° and 15°.

Geometric Measurement of 3D Models
Svoboda, Pavel ; Švub, Miroslav (referee) ; Šiler, Ondřej (advisor)
Work is discussing questions about measuring essential geometric property on model using OpenSceneGraph library. Program contains simple distance and angle measurement on model and distance and angle measurement on projection plane, which is defined by user. There is not missing usefull theory for measuring in Euclidean space, neither explanation of used methods and constructs for implementation by Open Scene Graph. For better understandig of work with OpenSceneGraph here is simply described use of OpenSceneGraph library. Manual and technical documentation is part of this work too.

Security application of mmWave sensors
Petržela, Lukáš ; Zamazal, Michal (referee) ; Valach, Soběslav (advisor)
This bachelor thesis is focused on possible use of Texas Instrument´s sensors in security systems, especially for perimeter securing. It includes the overview of radar technology principles and describe of Texas Instrument´s radars principle. Appropriate sensors location has been designed and implemented, and a communication protocol has been designed. The functionality and reliability of the proposed solution has been verified. The results are analyzed and evaluated.

Family house in Myjava
Mizerák, Maroš ; Kalužová, Alena (referee) ; Pěnčík, Jan (advisor)
The theme of bachelor´s thesis is new-building family house in Myjava. In the house is one living room on the first floor and four are in the second floor. The building is set in sloping terrain. It has two floors and one underground floor. Second floor is solved in the attic. It is a brick building, which is the system POROTHERM with a combination of BTB fittings in the basement. Roofing is solved by gabled roof with a pitch 32° and 37°.

Stereometric ultrasonic distance sensor
Nguyen, Thuc Tuyen ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
This bachelor thesis deals with designing and realizing a sensory system for detecting the presence of targets and its location. Target is located by two parameters: the distance and the view angle from sensory system. This system is set up by two ultrasonic distance sensors SRF02, driven by microcontroller Atmega128, using I2C communication protocol. The placement of the two ultrasonic distance sensors is optimized by using mathematical model, it enables the system to perform optimum accuracy and be able to observe the largest area possible. The measurement results then will be shown on LCD display module or they can be saved and used as input parameters for other tasks.
