Abstract:

Práca sa zaoberá objavujúcim sa nekonvenčným využitím moderných teodolitov, tiež známych ako Robotické Totálne Stanice (RTS), ako sledovací a navádzací systém, určením presnej pozície dynamicky sa pohybujúceho objektu. To sa týka najmä situácií, kde nie je možné využiť konvenčné polohovacie systémy akým je napríklad GNSS. Kinematicky určená poloha objektu kontinuálne sledujúcou RTS môže byť následne v reálnom čase využitá pre autonómnu navigáciu malých bezpilotných leteckých prostriedkov (UAV) poskytnutím referenčného súradnicového systému a okamžitej polohy v ňom. Podstatná časť práce je venovaná návrhu a realizácii vhodných experimentov, ktoré overia spoľahlivosť určovania presnej polohy objektu v presnom časovom okamžiku. Boli preverené stanice série S7 a S9 od spoločnosti Trimble a stanica S9 HP, ktorá disponuje frekvenciou kontinuálneho merania až do 10 Hz bola napokon využitá pre experimenty. Lokálny čas ovládacieho panelu TSC7, ktorý zabezpečuje komunikáciu so stanicou bol pomocou protokolu PTP synchronizovaný s lokálnym časom mini-počítača Raspberry Pi, ktorý následne poskytoval referenčné meranie skutočnej polohy objektu v čase. V závere sú zhrnuté výsledky experimentov.

Abstract:

Measurement of effect of L-carnitine by ergospirometry Summary The intention is to determine the effect of L-carnitine on fatty acid metabolism. Values like volume of utilized oxygen, performance and respiratory quotient were chosen for evaluation. The study is a randomized and placebo-controlled. The testing was performed on a treadmill with gas sensing device Cortex Metalyzer 3B and sporttester Polar RS 400. The measurement was adjusted compared to the pre-set test program. The reason was detecting a change in fatty acid metabolism, which takes place under aerobic conditions and starts later. Participants were recreational and performance athletes. Paired t-test and percentage change were used for evaluation. There was no change in the volume of utilized oxygen, performance and respiratory quotient. This study does not match with the majority of similar trials, which indicate the reduction of the respiratory quotient, reduced lactate levels, markers of increased oxidation of fatty acids and the other markers of aerobic metabolism.

Abstract:

This thesis describes application of image processing for precise distance measurement in self acting production of a tip for AFM microscopes. The main goal is to measure distances between assembly parts during fabrication process. The purpose is to acquire a data for self acting assembly line which have to substitute inaccurate and nonrecurring manual assembly process. The assembly process consists of three technological steps. In first two steps the tungsten wire is glued to the cantilever. Distance measurement is necessary in all axes for proper alignment of parts. In third step the sharp tip is etched by KOH solution. The right distance between liquid level and the cantilever must be kept. A camera with high resolution and macro objective is used to acquire an image. Camera image is then calibrated to suppress distortions and scene position with respect to camera position. Length conversion coefficient is also computed. Object recognition and distance measurement is based on standard computer vision methods, mainly: adaptive thresholding, moments, image statistics, canny edge detector, Hough transform… Proposed algorithms have been implemented in C++ using Intel OpenCV library. The final achieved distance resolution is about 10µm per pixel. Algorithm output was successfully used to assembly few test tips.

This thesis describes analysis and optimization of existing heating system aboveground fire sprinkler water tanks. The purpose is to design a heating system so as to achieve optimal operating and economic conditions for the operation of heating in winter. I will use available computer software and adhere to the applicable regulations and standards. Using experi-mental methods and computer simulations I will assess the current state of the heating system which in turn will provide an optimizing its use and operation.

Abstract:

Medical diagnostics using computed tomography or magnetic resonance is a common part of complex medical checkup for a long time. These devices produce vast volumes of data, which must be analyzed by an expert physician. There is a big space for utilising computers to aid medical diagnosis, or visualization. This work aims to measure volume of a specific organ in the human body, like kidneys or spleen. To measure volume of the organ it is necessary to reconstruct the object from three-dimensional data. Reconstruction is based on segmentation of the image data, which separates reconstructed organs from the background. The task of segmentation is specially adapted to this kind of data, which are, from specimen to specimen, characterized by big similarity in common shape, but also by big heterogeneity in tiny details. Deformable models were chosen as a primary tool for the segmentation of three-dimensional volumes. They are also the main topic of this work. Programs measuring volume in medical data exist, but thanks to increasing performance of modern computers it is possible to implement new algorithms, which are not present in today's software tools. The result of this work is a system which segments and measures volume in medical data. We also perform benchmarks, which expose an error of the measurement with...

Abstract:

The thesis deals with the detection of thermal bridges of the building envelope of SCHOTT s.r.o. and MANNTECO s.r.o. The aim of this diploma thesis is the experimental verification of thermal defects and anomalies of peripheral structures of buildings. The qualitative infrared thermography method is used to ensure the results. The results of the experimental measurement revealed thermal defects and anomalies on the peripheral shells of the measured objects. The acquired thermograms are evaluated. With regard to the measurement results, construction operations are proposed, which are suitable for the elimination of thermal defects and anomalies of the building envelope.

Abstract:

This thesis deals with gamma-ray field of size-limited uranium objects and with possibilities of their localization by a field radiometric measurement. The gamma-ray field attenuates progressively with distance from the ground source of radiation. The applied method of radiometric survey plays an important role in localization of a radioactive object. The gamma- ray field of uranium anomalous objects was studied for variable signatures of ground anomalous objects and different methods of gamma-ray survey by using mathematical modelling. The method of modelling was derived from fundamental theoretical laws describing the gamma-ray field of a point source. The verification of applied mathematical modelling was carried out by the comparison of calculated model of the gamma-ray field at three real uranium anomalous objects with experimental data of ground and mini-airborne measurement. Mini-airborne measurement was realized by the prototype of a gamma spectrometer Georadis D230A. This instrument is characterized by relatively high sensitivity compared to previously used similar devices. Airborne platform was a hexacopter Kingfischer. One of the aims of this thesis was to assess the applicability and technical capacity of D230A instrument. Calculated values of the gamma-ray field at different detection...

Abstract:

This thesis focuses on the problems with determining the dimensions of the timber during the processing with the harvesters. This study discusses all the possible variations in measurements, their origin and a resulting impact on the volume of the timber. Furthermore, this thesis describes other methods of measuring timber, such as manual measurement or measuring by sensing proportions of the timber with a saw measuring frames. The emphasis is on the variances in the calculation formulas, particularly focused on the differences in setting the reading bark. The research is supported by two measurements in the field, more specifically on the spruce vegetation. During these field measurements we performed the cuts with harvesters on the amount of 6 trees which were subsequently transported to the sawmill for the standard electronic checks. The log performed with the harvesters were afterwards measured twice for the purposes of precise volume measuring.

The thesis deals with the evaluation of the impact of the performance of three groups of business representatives in Coca-Cola HBC Czech Republic, Ltd. on corporate revenues, sales volumes. Compares the cost of three groups of dealers. Based on the outputs multi criteria analysis of the impact of the performance of groups of business representatives on criteria of internal solution is proposed the use of sales representatives in the future in order to increase the company's bottom.
