Electronic Compass
Špaňhel, Petr ; Slaný, Karel (referee) ; Šimek, Václav (advisor)
This bachelor's thesis deals with a design and construction of equipment that should offer an easy approach to measurement of temperature, air pressure and angular orientation to the Earth surface. Subsequently, this set of infromation will be shown in a concise way on a graphic LCD display. The introductory chapter provides a general outline to the hardware conception, which primarily involves reading of data from sensors and their graphical visualization. Details on control firmware aspects are included in the following two chpaters. Fourth chapter is aimed at device operation and its user interface. Finally, evaluation of the results and conclusion is provided.

Realization of fingerprint scanner
Kovář, Martin ; Sekora, Jiří (referee) ; Mézl, Martin (advisor)
This master’s thesis deals with the issue of scanning human fingerprints, which is currently very topical and represents the most widespread biometric technology. The theoretical part of the work acquaints the reader with basics of dactyloscopy and biometrics and concerns technologies used for fingerprinting, image preprocessing methods and commercially available contactless optical scanners. The practical part is a realisation of a contactless optical scanner based on a Raspberry Pi minicomputer, implementation of preprocessing algorithms in Python and testing of the device from the perspective of image quality.

Meaurement process automatization of Zener reference
Bábek, Tomáš ; Nováková Zachovalová, Věra (referee) ; Havlíková, Marie (advisor)
This thesis deals with metrology specialized to DC voltage. In the begining of thesis is explanation of technical terms from metrology, summarization of units from International System and explanation of the standards and its kinds in the context of metrology. Primary standards of DC voltage based on Zener diodes and Josephson effect are described as well. In cooperation with Czech metrology institute in Brno this work is focused on automatization of measuring Zener reference standards (ZRS). Goal of this project is to automatize the measuring of Zener reference standards and its relationship with Josephson voltage system using scanner. To do this, there is a need to find out offsets, that can develop on scanner's channels. There is a theoretical analysis of measuring made on the scanner and their uncertainties. Aim of the solution is computation of scanner channels offsets using everyday automatic measuring the system of Zener reference standards (ZRS). For measuring the LabView was used and for computing the data from measured values the Matlab was used. This thesis should short the time needed when measuring DC voltage references, measure values of DC voltage standards and set the scanner channels offsets. In the end there is a summarization of offsets measured on individual scanner channels.

Engine Motormanagement Software
Huška, Lukáš ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
This master thesis deals with ignition systems which are used in cars vehicles with gas engines and also with setting of the best moment of ignition of gasoline-air mixture in cylinders of engine. Ways of gas injection at diesel engines and their control systems are also described in this thesis. Next chapter deals with control unit and describes main actions which are necessary for today’s motor vehicles. As illustration is used example of succession of actions which are necessary for calculation and setting regular value of pre-ignition. At the end is shown animation, which can be used for practice lessons in a subject Automobile Electric and Electronic Systems as a example. It will simplify understanding of described activities which are all accomplished by central control unit. For purposes of laboratory lessons is in this thesis also discussed measuring of engine performance with changes of parameter of central control unit.

Scanning capillary column by color scanner and zones recognition
Wojnar, Petr ; Petyovský, Petr (referee) ; Štohl, Radek (advisor)
The master’s thesis focuses on creating an application for scanner control through WIA interface. This aplication is used for reading capillary during electrical separation methods in analytic chemistry. Scanned pictures of capillary are possible to process using online application for detection of significant zones within experiment. Offline detection of a set of scanned pictures is also possible. These applications have been created in LabVIEW environment made by National Instruments.

Approaches to the implementation of document imaging systems
Kapicová, Eva ; Šedivá, Zuzana (advisor) ; Vondrouš, Martin (referee)
This thesis is focused on document imaging and describes different approaches to the implementation of document imaging systems. In the first part there is the theoretical background of the document imaging that is supplemented by current statistics. In the first part there are also some remarks on the situation on the Czech market. The second part is based on examinations of different approaches to document imaging systems that were made by Czech companies. The main objective of this thesis is a practical example of selecting an appropriate solution of the document imaging. There are considered three types of approaches to the document imaging: complete outsourcing, in-house outsourcing or a solution of their own. To achieve this goal there is an adequate theoretical basis for the document imaging and an overview of hardware and software support for digitization in the first part of the thesis. TEI method by Forrester Research is used for comparison of the economic impact of the different approaches. The contribution of this thesis is primarily in the description of the state of document imaging in the Czech Republic and also examination of different solutions and approaches to the document imaging. There is also a completion of the theoretical part by a data from current surveys.

Documentation of some botanical objects by table scanners
Babůrek, Ivan
Table scanners may be used for documentation of biological, and especially flat botanical, objects in laboratory. In comparison with (digital) photography is picture from scanner mostly cheaper and quicker. In comparison with classical botany herbaria picture better catch the shape and colour of fresh biological object. Small 3D objects (seeds, fruits) may be also scanned without problems. Resolution 600 dpi is higher than that of human eye. Scanned picture may be used instead of using small magnifying glass.
