Usage of 3D scanning in precise injection moulding
Chylík, Michal ; Čudek, Vladimír (referee) ; Zatočilová, Aneta (advisor)
The aim of this bachelor thesis is creating a complex study on the topic of 3D scanning and reverse engineering regarding technical praxis. Part of this bachelor thesis are three examples of usage. Using 3D scanner for reconstruction of plastic parts in marketing praxis, specifically for recovering of missing data and subsequent valuation. Using 3D scanner as an inspectional tool - a support for measurement of quality of plastic moulding. And last but not least an option of creating an identical part to fit requirements of tool shop. The drawing documentation including protocol for inspect and 3D models are included in the thesis.
Methodology of digitizing, 3D documentation and 3D visualization of the various types of monuments
Brůna, Vladimír ; Větrovská, Barbora ; Marek, Zdeněk ; Brejcha, Marcel ; Frouz, Martin ; Frouzová, Martina
The objective of the methodology was to cover the field of spatial digitization only partially, and for this reason it was narrowed to the leading method of 3D laser terrestrial scanning, broadly used for large objects such as castles, churches, villas, constructions, stone sculptural objects such as statues, coat of arms, cornice. It is aimed at the researchers and institutions in the field of the cultural heritage protection, the prominent of which is the Ministry of Culture of the Czech Republic, the National Heritage Institute, bodies of the national heritage care, universities and high schools with accredited subjects in documentation of monuments and museums and art galleries.

Digitalizace historických map a jejich využití pro sledování změn v katastrálním území Sedlec
Smutná, Ivona
My thesis is focused on mapping the changes in the landscape today and also from a historical perspective. Specifically, it focuses on the cadastral area. Sedlec near by Náměšť nad Oslavou. The work deals with two periods. From a historical perspective in the year 1953 and at present, the year 2014. The first step was to map the contemporary landscape and plot that on paper maps of the cadastral area. Followed by entering data into the electronic map for this step, I used the program ArcGIS and freely available map data from internet servers. I plot cadastral area, arable land, permanent grasslands, gardens, forests, built-up area, water areas and streams on the map. In conclusion, my task was to compare today's condition of the landscape with the historical map and evaluate decrease, increase or change of using these areas.
A multi-source power station switch- and control-boards digitization project
Fiala, Martin ; Bátora, Branislav (referee) ; Drápela, Jiří (advisor)
This bachelor´s thesis deals with comprehensive proposal and reconstruction of switchgears for source power station on Department of Electrical Power Engineering with controlled rotating and static power sources, that can be managed remotely using a programmable logic controller via the communication link. Part work also description of the control system and all the necessary parts for reconstruction. At last this thesis deals with the problem, which is linked to the deployment of automation in general, including the negative aspects, describes the problem of industrial communication systems along with the most used fieldbus that is used in the implementation of automated solutions.
Measurement of the rain rate instantaneous value using acoustic method
Kresta, Daniel ; Poliak, Juraj (referee) ; Wilfert, Otakar (advisor)
This thesis deals with implementation of the rainfall rate measurement using an acoustic method. It is divided into four parts. In the first part of the thesis a necessary theoretical knowledge is analysed. The second part contains a design of a workplace used for the measurement. The third part presents and analyses important experimental recordings acquired in the workplace. Then all measured values are processed and applied in the measuring program. The last part summarizes results of the thesis, advantages and disadvantages of using the acoustic rainfall rate meter.
Current sensor with digitized output signal
Hanuš, Ivan ; Vágner, Martin (referee) ; Havránek, Zdeněk (advisor)
The objective of this thesis is to describe principles of measuring of alternating current in low voltage power supply network with Rogowski coil and to study details of requirements for electronic current sensor with digital output. Furthermore to study the current solution of digitalization of output signal from Rogowski coil and to determine metrological characteristics of the digitalization module for processing the signal from the Rogowski coil as current sensor and to design a concept of an electronic current sensor unit with Rogowski coil and the digitalization module with the expected optical output. The theoretical part deals with the measurement of current using Rogowski coil, its characteristics and advantages compared to conventional current transformers. Further in the thesis there are specified the requirements for current sensor. The practical part deals with the design of digitalization module consisting of a pair of AD converters, a microcontroller and output circuits. Furthermore, the thesis deals with digital signal processing of signal from Rogowski coil. Furthermore, the thesis describes firmware for microcontroller and PC application. The result of thesis is functional circuit of electronic current sensor that processes signal from Rogowski coil and converts it to digital form.
Design of Portable 3D Scanner
Štigler, Jaroslav ; Rubínová, Dana (referee) ; Sovják, Richard (advisor)
The topic of this bachelor‘s thesis is design of handheld 3D scanner. This scanner belongs in the higher price category. This thesis deals with problems like long working time, watching monitor during scanning, versatility and safety measures from mechanical damage. Ergonomic solution is also very important. This design is based on a simple and functional shaping. Shaping and color solution corresponds with its use in industry. This scanner also can be used in other fields (for example: medical sector, design, archeology, etc.).
Ancient Maps Digitizing
Pospíšil, Josef ; Šilhavá, Jana (referee) ; Španěl, Michal (advisor)
This work is about processing of historical maps, especially their digitizing and vectorization. The main focuses of this project are maps from the second historical military mapping and finding methods useful for removing texts from these maps.
Determination of efficiency of hydraulic drive with recuperation
Kobza, Michal ; Robenek, Dětřich (referee) ; Nevrlý, Josef (advisor)
In the first part of the thesis is determined efficacy criterion for the individual operating modes of the experimental stand with energy recovery and subsequently are evaluated the records of individual measurements. Energy savings are calculated with using energy recovery. The second part describes the process of digitizing relative fuel consumption map of the engine. Results are confronted with a real application engine in the road roller Ammann AP 240 H. In addition, the master thesis describes the creation of hydrostatic converter block in the program MATLAB/Simulink 2012b. Creating block can be used in the development of simulation models.
