Distance and Speed Measurement Based on Ultrasonic Transmitters and Receivers
Šumbera, Adam ; Růžička, Richard (referee) ; Strnadel, Josef (advisor)
This thesis is engaged in measuring of distance and speed by ultrasound, based on microcontroller Freescale MC68HC08. Describes the function blocks of whole embedded system and its physical realization. Theoretically discuses about properties of ultrasound and deals with problems paired with transmitting and recieving.
"Dostihy a sázky" Board Game GUI
Očenáš, Marek ; Kubát, David (referee) ; Kněžík, Jan (advisor)
The aim of this bachelor's thesis is to create the interface (GUI) for board game Dostihy a sázky Horse-racing and the betting) which allows user (player) to control the game on virtual game plan and supervises following of all game rules. In the text of this thesis the game itself is described with its rules, design proposal of GUI and arrangement of game components in the main window, implementation proposal of game rules not to allow the player to play against game rules and proposal of securing network communication of several such interfaces. Further the final solution is described and its alternation towards proposal with examples of program appearance.
Automatic Estimation of Distance between Vehicles
Beran, Martin ; Špaňhel, Jakub (referee) ; Sochor, Jakub (advisor)
This thesis deals with the automatic estimation of distance between moving vehicles. The resulting files contain edited video showing the distance. The solution is implemented in C++.
Distance and Speed Measurement Based on Ultrasonic Transmitters and Receivers
Vláčil, Martin ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
Thesis deals with issues connected with using ultrasound to measure distance and speed od objects. In details analyses principle of such measurement, its limitations and difficulities. In thesis is presented way of possible solution and its testing in praxis, such as idea of its further improvement.
Objects outline and image matching
Kvasnička, Petr ; Richter, Miloslav (referee) ; Janáková, Ilona (advisor)
The aim of the diploma thesis is to get acquainted with problem of detecting the object with sketch, diagram or contour, which should represent the object to be compared. The thesis deals with how to solve this problem. Part of the thesis contains theoretical methods that manage to evaluate the degree of similarity between the unknown object and less accurate sketch. Each of these methods includes customized edits from the viewpoint of image pre-processing. The thesis deals with some methods in more detail. Selected methods are implemented and tested on the created database. In the last step of the thesis these realized methods are compared to each other.
Similarity/dissimilarity analysis of genomic data on the basis of graphical representation
Těthal, Jiří ; Provazník, Ivo (referee) ; Maděránková, Denisa (advisor)
The work deals with the identification of species of animal through the density of nucleotids of mitochondrial gene CO1. In the first part the theory summarized information about DNA barcoding and the mitochondria, cellular organel that with this method is closely related. The second part deals with virtually comparing different sequences using the density of nucleotides. For this it was created program, which uses two functions, the first of the specified nucleotide sequence calculates the density and one can compare the density by distance methods.
Data transmission in mobile networks
Bílek, Petr ; Molnár, Karol (referee) ; Havelka, Dušan (advisor)
The Bachelor’s thesis deals with mapping and usage of mobile networks of data transfers. It describes every particular generation of networks and technologies that they can use. This thesis is divided into two main parts, theological and practical. In the first part, the technologies of the second and third generation currently used for data transfer in mobile networks are described there. This concerns especially GPRS, EDGE and UMTS services. The thesis focuses on modulations used for these technologies, together with the coding and bit rates possible. It compares their advantages and disadvantages and presents their utilization among national operators. It also tries to sketch out the way the data services of mobile networks will proceed. The second part of the thesis is also divided into two parts. The first one is the simulation of the UMTS network with the assistance of the OPNET Modeller 14.5 environment. In this case, the thesis aims at two important characteristics - such as the dependence on the bit rate and distance of the primary station, and dependence on the bit rate and total load of the whole network. Both characteristics are observed mainly because of the bit rate and power characteristics. It describes objects and funcions of the OPNET environment. The next part in the practical section is the factual measurement of the Internet 4G service, provided by T-Mobile operator. The thesis focuses here on the presentation of the outcomes which were accomplished by the practical measurement of that service. The end of this thesis is dedicated to the comparasion of simulated outcomes with the outcomes practically measured, and to the conclusion of the results emerged from them.
Calibration of Surveillance Camera
Pištělák, Radek ; Hradiš, Michal (referee) ; Herout, Adam (advisor)
This work aims the issue of calibration of cameras, more precisely surveillance cameras, that monitor Ćat areas such as car parks. The calculation is based on several measurements of the same distance over the entire Ąeld of camera view. From the obtained set of measurements, the properties of the camera are calculated so that it is able to measure distances. With this approach, an error of 1.6 % was achieved, which was calculated by substituting back into annotated and unannotated images in the main experiment. The result of the work is a way to calibrate the camera with a view of large spaces, for which other methods of calibration could be difficult.
Face Identification
Částek, Petr ; Jaša, Petr (referee) ; Chmelař, Petr (advisor)
This document is trying to introduce the reader with issues of identifying the face connected with miscellaneous scanning technologies and enviroments. Inside this document there are mentioned some possibilities of creation unique print of a face so that there would be denied unwanted effects of enviroment and the identification of persons would be possible.
Emotional Cartography
Rygálová, Monika ; Pfeiffer, Jan (referee) ; Sterec, Pavel (advisor)
The work aims to artistically compile perception of maps as a fact, what let us think about The world - how we know it from the map. I work with data, which I gain by displaying technology – eye tracking, which helps me to record track of moving eyes during watching any kind of picture. The observations will be people from different places such a place of stay etc. Gained data I am going to use as a study, which I will componate to maps and different vizualizations of world, countries etc. "Where i have not ever been before, it does not exist" – is idea of percepting world, wich I also work with on that project. Study will contain all aspect of perceiving maps and systematicly shown world related to the person, his memories to that place, fyzical contact and his impact in his scale person versus a the world.
