An accurate comparison of the methods for passive IP Geolocation
Mrázová, Andrea ; Komosný, Dan (referee) ; Verner, Lukáš (advisor)
This thesis aims to evaluate the physical location of the stations connected to the Internet, focusing on passive methods of IP geolocation, specifically by using geolocation databases. The first part is generally described what it is IP geolocation, the second section describes the active and passive methods of IP geolocation and the third section describes the practical parts of assignment and the results that we found.

Measurement of transfer speeds and delays in computer networks
Bárdossy, Adrián ; Kubánková, Anna (referee) ; Jeřábek, Jan (advisor)
Bachelor thesis is interested in measurement of transfer rate and latency in computer networks. In the first part of thesis is defined, which motodics of measurement we know, various RFC and their specifications, also various parameters about measurement in computer networks like bit rate, capacity of channel, latency. In the second part are prepared users interfaces and softwares for applying the measurement of thesd parameters. In the last part is application of these softwares and creating and testing methodic of network measurement.

Process Calibrator M143 - Climatic Testing
Dojava, Václav ; Bartoň, Jan (referee) ; Havlíková, Marie (advisor)
Subject of the bachelor thesis are the climatic testing of the M143 calibrator. Theoretical section of the thesis is concerned with the analysis and description of the norms used during climatic tests of electronic devices. Thesis then continues by describing properties and functions of the M143 calibrator and the Caliber programme, which is performing automated measurement during the climatic tests, on the basis of the designed calibration procedure. Practical section of the thesis describes the designed testing points and climatic conditions, which are adjusted during the testing. In this section the testing points are implemented to the Caliber programme. Last section contains the analysis and evaluation of the measured data gained during the climatic testing. From these measured data, we are to determine, whether the M143 calibrator is within the specifications stated by the manufacturer in different climatic conditions.

Application of robotic total station for crane tracks measurement
Chomjak, Ján ; Foral, Jakub (referee) ; Machotka, Radovan (advisor)
This diploma thesis deals with application of robotic total station for crane tracks measuring. To determinate straight of rail tracks was used system of automatic target recognition. One crane track was measured by two methods. Horizontal deviation from straight direction was determinated directly by the method “line of sight” and indirectly using measuring angles and lengths. To determinate height continuance was used engineering and trigonometric leveling. The results of measuring proved, that reached deviations between methods are minimal, so we consider them as equal. System system of automatic target recognition reliably and with sufficient accuracy aims to the prism-centre.

Costing in the Selected Firm
Zelinková, Petra ; Vrtalová, Jana (referee) ; Hanušová, Helena (advisor)
The Master´s thesis deals with standard costing method and its implementation in service company which especially fixes and varnishes cars. This work is divided into three parts – theoretic, analytic and proposal. The theoretical part deals with the charactersics of costs and methods of calculation, especially standard costing. The analytical part describes the current status of the company in which the method should be implemented. In the design part the process of iplementation is analyzed.

Voltage References in Bipolar and CMOS Process
Kotrč, Václav ; Prokop, Roman (referee) ; Kadaňka, Petr (advisor)
This diploma thesis deals with precise design of Brokaw BandGap voltage reference comparing with MOS references. There is STEP BY STEP separation and analysis of proposed devices, using Monte Carlo analysis. There are also presented the methods for achieving a lower deviation of the output voltage for yielding device, which needs no trimming.
