Měření přetvoření mostní konstrukce a železničního svršku / Deformation Surveying of Bridge Construction and Railway Track

Staněk, Boleslav January 2014 (has links)
This diploma thesis deals with the phases measuring deformation of the bridge construction and railway superstructure on the bridge over the river Dyje in Breclav and its surroundings. The main goal was to determine the longitudinal displacements of the rail web and the bridge structure. The object of this thesis was also transverse displacements which have been caused mainly due to temperature changes. The introduction describes the location. The following section discusses the methodology terrestrial deformation measurements and calibrations selected surveying devices. Furthermore, there is stated the processing of measurements and the calculations. In conclusion, the thesis evaluates the longitudinal and transverse displacements, which are shown in the annexes.

Plánování a analýza pohybu zařízení pro absolutní kalibraci GNSS antén / Movement planning and analysis of device for absolute GNSS antenna calibration

Hynčicová, Tereza January 2014 (has links)
The thesis is aimed at movement analysis and planning of a robotic device for absolute GNSS antenna calibration, which is developed at Brno University of Technology, Faculty of Civil Engineering, Institute of Geodesy. The first section is devoted to independent verification of the temporal synchronization of the robotic device’s movement, which is a prerequisite for the successful antenna calibration. The following section is focused on analysis of moveable characteristics since their knowledge is crucial for the following movement planning. Method of the device’s movement shooting by camera and evaluation its position based on gained photographs is used for both testing measurements. The final part is dedicated to movement planning, especially to calibrated antenna weighting influence on device’s movement characteristics, test results implementation into the observation program and arm movement planning considering the homogeneous calibration measurement layout.

Optimalizace spotřeb energie v administrativní budově / Optimization of energy consumption in an office building

Horká, Lucie January 2015 (has links)
The main aim of this thesis is optimization of energy demands in a new administrative high-rise building Vienna Point II located in Brno. Experimental part of the thesis deals with determination of real energy consumption during winter season and preparation of a set of climate data for theoretical simulations. Theoretical part is based on data obtained by experimental methods and is aimed on optimization of energy demands. The effect of suggested solution is analysed by software solutions which simulate building operation. Resulting energy demands obtained by simulations are compared with real energy consumption.

Optimalizace štěrbinové vztlakové klapky letounu / Optimization of single slotted flap

Dvořák, Petr January 2009 (has links)
The main objective of this diploma thesis is to optimize the high lift device on the wing of the Phoenix Air U-15 ultralight aircraft, so that it complies with the UL-2 regulation regarding the stalling speed – 65 KPH. This is fulfilled by optimization of the slotted flap position. Methods used include the Response Surface Method and the Computational Fluid Dynamics approach – namely Ansys Fluent v6 software package. Furthermore, the paper deals with take-off flap optimization and construction of the flap deflection mechanism.

Kalibrační postupy etalonu Datron 4920 / Calibration rutines of the standard Datron 4920

Schinneck, Jakub January 2016 (has links)
This master’s deals with the calibration routines of the alternating voltage measurement standard Datron 4920. The first part introduces the basic terminology of metrology, its history and organizations specializing in metrology. The thesis describes the alternating voltage at the highest metrological level through AC/DC difference. The theoretical part also describes the alternating voltage measurement standard Datron 4920 and its measurement functions together with the calibration routines. The main aim of thesis is to create the calibration procedures AVMS Datron 4920. Based on the created calibration procedures, a flowchart of application for calibration routines is designed. The practical part then continues with programming application for calibrating AVMS Datron 4920 based on the created flowchart. In conclusion, the application is tested at selected points of measurement and an analysis of measurement uncertainties is carried out.

Automatická regulace velikosti písma podle vzdálenosti čtenáře / Font size adjustment based on distance detection

Brunclík, Robert January 2016 (has links)
The thesis deals with automatic control the font size by the distance from the reader. It includes theoretical acquaintance with the face detection and subsequent tracking of the detected area during the scene. Furthermore, there is a comparison of the tracking algorithms. Then the calculation of distance is decribed. It is based on the user’s calibration and based on the outcome occurs the font size is automatically corrected. There is also a description of a separate application Automatical controller of the text size, with the recommended settings of the program.
