Návrh gaussmetru s tříosou měřicí sondou / Gaussmeter design with three-axis measuring probe

Hejtmánek, Tomáš January 2018 (has links)
The purpose of this work is the design of a gaussmeter with a three-axis probe for magnetic field mapping and subsequent reconstruction of the image using magnetic impedance tomography. Commercially available gaussmeters have low bandwidth for these purposes, and signals cannot be measured in synchronous detection mode. The aim of the thesis is select the most suitable magnetic field sensors for the MIT purposes and to design the entire measuring device to meet the measurement requirements in the wider frequency band and synchronous detection. Attention will also be paid to designing a suitable mechanical design of the probe and the location of the sensors. The proposed device will be tested and evaluated for MIT purposes.

Detekce prostorových objektů v mračně bodů / Detection of spatial objects in a point cloud

Venený, Petr Unknown Date (has links)
The diploma thesis deals with processing of a point cloud that was collected via mobile mapping system. The first part sets a theoretical background, starting with mapping in general moving to mobile mapping systems and their particular parts. The practical part describes the whole process of data collecting, testing the automatic detection of spatial objects based on a point cloud and its visualisation. The results of the diploma thesis are GIS data layers and an evaluation of the process.

Návrh optimálního zásobovacího procesu pro nové zakázky / The Suggestion of Optimal Supply Process for New Orders

Adamík, Vít January 2019 (has links)
The topic of diploma thesis was implemented in selected mechanical engineering company producing precision parts in small series. The main aim of the thesis is to create the suggestion of optimal supply process for new orders. The first part of thesis describes the company, area of its business and the processes of the order. In second part, the production analysis is carried out: production order path, production analysis for two reference parts, comparison of all time delay over two last years, find bottlenecks in the supply process. Base on analysis, theoretical approaches was described. In the last chapter there are suggestions for improvement of supply processes and thus shortening of production time of new orders.

Metody temporálního tone-mappingu HDR videa / Temporal Tone-Mapping Methods for HDR Video

Staněk, Jiří January 2019 (has links)
The diploma thesis provides the theoretical background needed to understand the complex topic of high dynamic range, and deals with the implementation of an innovative method for temporal video tone-mapping. At first, high dynamic range image acquisition, storage and processing are described. Afterwards, a general introduction to tone-mapping, description of undesirable image artifacts and an overview of existing state-of-the-art algorithms are presented. The part which follows focuses on the implementation of the chosen method and proposes several additional enhancements of the initially selected algorithm. Based on the information provided, an application with an intuitive graphical interface, which can be used for temporal HDR video tone-mapping, has been created. Finally, the the achieved results are demonstrated and visually compared with existing methods for temporal video tone-mapping.

Mapování trajektorií pohybu chodců v záznamu pořízeným dronem / Mapping of the Pedestrian Movement Trajectory in a Video Recording Captured by a Drone

Šťastný, Filip January 2020 (has links)
This master's thesis deals with pedestrian detection using neural networks in a video record captured by drone. Pedestrians are tracked, and their GPS coordinates are calculated using digital elevation models and mapped based on their identity and an information provided by the drone.

Analýza zubů a kostí metodou spektroskopie laserem buzeného plazmatu / Analysis of teeth and bones by laser-induced breakdown spectroscopy

Šindelářová, Anna January 2021 (has links)
The presented diploma thesis deals with the elemental composition of hard tissues – human and murine jaws studied by laser-induced plasma spectroscopy (LIBS). Samples of human teeth contained a disease called ankylosis and the difference in elemental composition of healthy and diseased tissue was observed to localize ankylosis in the tooth. When evaluating the map of the spatial distribution of phosphorus and calcium, a decrease in the concentration of these elements in the ankylosis infected area was observed. Furthermore, murine jaws containing lead were analyzed. When assessing the spatial distribution of lead in tissue, it was found that lead was incorporated in murine teeth in the enamel at the tip of the incisor and molars. In conclusion, LIBS method achieved good results considering the detection of the elemental distribution of hard tissues. It enables to differentiate parts of the tooth in terms of elemental composition and tissue hardness and also to detect changes in the matrix caused by a disease or bioaccumulation of heavy metals.

Analýza výkonnosti procesu / Process performance analysis

Vintrlík, Jan January 2011 (has links)
Presented thesis entitled “Process performance analysis” deals with problems in identification of the causes of the increasing cost and declining quality of the products, their minimization or complete removal. Further analysis will address the cost of low quality, serving as a basis for possible recovery of the fleet. All material presented in this thesis were collected in the company of NEVOGA, s r.o. engaged in manufacturing parts for the construction industry.
