ADVANCED REGRESSION MODELS
Rosecký, Martin ; Popela, Pavel (referee) ; Bednář, Josef (advisor)
This thesis summarizes latest findings about municipal solid waste (MSW) modelling. These are used to solve multivariable version of inverse prediction problem. It is not possible to solve such problem analytically, so heuristic framework using regression models and data reconciliation was developed. As a side product, models for MSW modelling using PCA (Principal Component Analysis) and LM (Linear Model) were created. These were compared with heuristic model called RF (Random Forest). Both of these models were also used for per capita MSW modelling. Theoretical parts about generalized linear models, data reconciliation and nonlinear programming are also included.

Model of the metropolitan optical network
Prudík, Jiří ; Hudcová, Lucie (referee) ; Křivák, Petr (advisor)
The purpose of this master’s thesis is foremost to provide a simple guide how to build elements of optical metropolitan area network. The basic model consists to sequence of construction, network topology, passive and active parts. The collection contains examples of alternative technology such as Wireless LAN with different frequency. The optical network construction based on optical cable, fibres, splices, trays, adapters, connectors and active parts for example a lot of media convertor models. After that there are demonstrating type of wavelength division multiplexer used in metropolitan area network – passive planar PCL splitter. One of the passive planar splitter are used to increase optical fibre channel. At the end of the collection a simplified examples of used measurements – optical time domain reflectometry and optical fibre transmission. Contains standard protocols or reflectogram. The conclusion of this thesis summarizes costs of FTTb (Fibre To The Building) model of optical metropolitan area network in Czech republic and future contribution for society.

Certifikation of Metrology Laboratory
Krbušková, Julie ; Fiedler, Petr (referee) ; Havlíková, Marie (advisor)
This bachelor’s thesis considers certification problems of Metrologic laboratory. Individual ISO standards (9000, 9001, 9004, 19011) needed for certification of companies are analysed in it. Also in this thesis there is elaborated manual of quality for Metrological laboratory of company Alfa. Further on I elaborate here schedule for calibration of devices in Excel with automatic monitoring of state and at last I check up management of Metrologic laboratory from the view of external auditor.

3D shape from camera pair
Bastl, Jiří ; Horák, Karel (referee) ; Richter, Miloslav (advisor)
The aim of this bachelor thesis is to create methods for obtaining 3D data from 2D images. This data will be used as an input data for algorithms which will process them into data formats creating 3D perception. In this work problem of rectification when we compare one image according to the other is solved as well as the problem of calculation of the model of a scene scanned with two cameras.

The Precise Measurement of Magnetic Azimuth
Junasová, Veronika ; Levek, Vladimír ; Šteffan, Pavel
This article deals with measuring magnetic azimuthusing inertial sensors. It introduces the steps in this process andobstacles that need to be solved in order to achieve more preciseresults. The magnetic azimuth can be determined using onemagnetometer; however, the precision in such measurement islimited. Therefore, this article also introduces measurement ofrelative azimuth acquired by the gyroscope. The essential part ofprecise measurement is the calibration of the mentioned inertialsensors, which is described in detail. The process of calibration issupported with equations, graphs, and tables. The measurementitself consists of an output from the magnetometer. The relativeazimuth acquired from the gyroscope is then combined using acomplementary digital filter with magnetic azimuth from moreaccurate magnetometer. The final results show the improvementobtained with the presented method. The article also containsinformation on a compact device designed for simple calibrationand measurement with the mentioned sensors.

Calibration and evaluation of data from strain gauges
Dubina, Jozef ; Jaššo, Kamil (referee) ; Vyroubal, Petr (advisor)
This bachelor's thesis describes calibration and evalution of data measured from tensometric sensors. The labour describes tensometers in general, their functions, aplications and principle of operation. Loading data from tensometric sensors is next part of this labour, where are informations how to convert analog signal to digital signal output, which is ready for processing and shows real values. After the signal is converted to digital, it is needed to calibrate tensometers to reach high precission values of weight according to reference load. Bachelor's thesis describes choices of electronic and mechanical components used for developing of digital scale. Software developing for this electronic device is described in next part of this thesis.

Mobile Signal Generator for ECU Calibration
Pauliuchenka, Aliaksandr ; Kučera, Pavel (referee) ; Svída, David (advisor)
The subject of this thesis is a mobile electrical signal generator for the calibration of an Electronic Control Unit (ECU). The thesis primarily offers an analysis of the electrical signals that enter the control unit. It then describes the process of developing the Printed Circuit Board (PCB) used in the generator, the C++ programs for the microcontrollers used, and the software for controlling and programming the test scenarios. Finally, the thesis concludes by measuring the output signals of the generator with an oscilloscope and testing the connection to an open ECU. Based on these tests, the functionality of the generator was evaluated.

Assessment of pressure conditions in the water supply network of the municipality of Ústí
Kuchař, Jakub ; Rajnochová, Markéta (referee) ; Ručka, Jan (advisor)
The bachelor's thesis is devoted to the hydraulic analysis of the water supply network of the municipalities of Ústí, Skalička and the settlement of Kamenec. The village is located in the Přerov district. The first chapter describes the theory of mathematical modeling and the basic relationships for calculation in pressure pipe systems. A quasi-dynamic hydraulic model of the entire area was created from the measured pressure values of the water supply network. The assessed values were displayed in the EPANET 2.2 simulation program. With regard to the character of the development in the municipalities, the pressure conditions in the area were assessed using the result. The last part of the work is dedicated to proposing measures to optimize pressure conditions and the resulting impact on the territory.

Býčí skála cave documentation - part Mořské oko
Ulčík, Vojtěch ; Machotka, Radovan (referee) ; Kratochvíl, Radim (advisor)
The bachelor thesis deals with documentation of the part of cave system Býčí skála, namely of the passages Kaňony and Mořské oko in the form of a ground plan, extended longitudinal section and cross sections in the scale of 1:250. The work contains a description of the location where the work took place. It also deals with the process of creating, specifically reconnaissance, measuring the creating a surveying network, detailed mapping and producing the resulting map in the JTSK coordinate system and the Bpv vertical system. A speleological measurement method using the Disto X2 instrument and producing a measurement sketch on a tablet in the Topodroid program were used for the measurement.

Camera testing
Frigyik, Tomáš ; Kratochvíla, Lukáš (referee) ; Richter, Miloslav (advisor)
This bachelor's thesis deals with the issue of capturing raster images using cameras and the current state of this issue, the appropriate setting of camera parameters that include external and internal parameters, the design of a measuring set for testing these parameters, while using the designed patterns generated on the monitor. This work also deals with the design of suitable models for setting parameters, the method of their generation and processing. The next part of this work shows a set of images and their processing, evaluation of the properties of the proposed processing procedure and determination of applicability of patterns.
