Stabilizační a autopilotní systém pro RC model letadla / Stability and autopilot system for airplane RC model

Čamaj, Peter January 2014 (has links)
The master thesis deals with design and realization of stabilizing and autopilot system, which is used in radio controlled model planes. The thesis contains a proposal of hardware platform, which is able to control the plane model based on data measured from a sensor system. Moreover, this thesis describes a software implementation of individual modules, which is measured the onboard values. The basic principles of stabilization and autonomous flight control are also summarized. In conclusion, the system is subjected to flight tests.

Vibrodiagnostika asynchronního motoru / Vibrodiagnostics of induction motor

Mašin, Dominik January 2015 (has links)
This thesis is dealing with measuring and evaluation of vibration signal. Vibration measurement is one of the most important operation for correct and fluent machinery service, not only from economical point of view but also because of security. Status monitoring of electric machine is a key to detect damaged parts and it is giving us an opportunity to avoid unexpected outages and failures in production. My work describes basic concepts and principals of vibration measurement. Asynchronous motor measurement and its evaluation is performed in practical part.

Štúdie zarovnania Belle II vrcholového detektoru a rýchla sin 2 phi analýza / The Belle II vertex detector alignment studies and prompt sin 2 phi analysis

Kandra, Jakub January 2021 (has links)
This thesis is focused on the alignment studies of the vertex detector during first years of the Belle II detector operation and the first prompt sin 2ϕ1 analysis using the first rel- evant data collected by the detector. Firstly, the Belle II detector and the SuperKEKB accelerator is introduced. Secondly, the software framework and tools operation is ex- plained, then the alignment procedure and developed validation procedures are described in detail. Fourth section reports about the first years of the detector operation. Next three sections are related to different alignment studies during thee different periods of the vertex detector operation: the Phase 2, VXD Commissioning and beginning of the Phase 3 early. The last section covers the time-dependent CP Violation and mixing measurements performed using the data collected prior to the 11en of May 2020. 1

Systém sběru dat z bezdrátových snímačů / Wireless data acquisition system

Kováč, Jakub January 2015 (has links)
The aim of this work is design of system for wireless data collection from energy meters. The work shows issues of smart metering and explains meters communication. There is designed and described concept of the system composed of RF modules connected to data concentrator. Designed RF module uses SoC radio CC430F5137 and it is connected to a data concentrator via RS485 bus. For the purposes of communication as well as firmware update, the communication protocol is designed. In the next part the work focuses on design and creation of RF module frmware, bootloader for RF module and software application for energy meter data processing.

Měření nerovností povrchů vozovek geodetickými metodami / Pavement Roughness Measurement with Use Geodetic Methods

Gašparík, Michal January 2016 (has links)
The issue of this diploma thesis is measurement of pavement roughness with an alternative means of data acquisition and evaluation by geodetic methods. In the beginning there is an overview of current state of actual roughness measurement methods. The main work is concerned with data acquisition with passive reflection of the laser rangefinder and laser scanner and standard deviations that arise in measuring on asphalt and concrete road surfaces. The aim of the work is to formulate the process of data acquisition, specification of standard deviations in the process of measuring, evaluation of pavement roughness according to ČSN 73 6175 standard, and their applicable graphic interpretation. Based on the analysis of accuracy of the methods applied, their usefulness is evaluated in comparison with the straightedge test.

Souběžné měření povrchového potenciálu a transportní odezvy grafenových Hallových struktur / Simultaneous measurement of surface pontetial and transport response of graphene Hall bars

Štrba, Lukáš January 2020 (has links)
Graphene is a semimetal with zero band gap. Position of Fermi level can be changed by applied gate voltage, which results in a change of free carier concentration. This work focuses on a simultaneous measurement of surface potential by Kelvin probe force microscopy (KPFM) and transport response of graphene Hall bars in different relative humidities and with applying gate voltage. The transport response was also observed in case of graphene Hall bar structure modified by local anodic oxidation (LAO).
