Kvantitativní analýza predikce poptávky u vybrané společnosti / Quantitative analysis of demand forecastingUrbanec, Matěj January 2014 (has links)
This thesis deals with the prediction demand forecasting in a company, focusing especially on quantitative methods of prediction. The theoretical part presents the predictions of demand, its place and importance in a company. Secondly, it presents various methods of qualitative and quantitative demand forecasting and the methods for measuring prediction accuracy. The practical part applies several methods on a real data of the company. These are the methods of moving averages, exponential smoothing, Holt and Holt-Winters method and the simple linear regression. The accuracy of each method are compared with each other and most accurate method is then used to predict demand for the year 2015.

Odhad přesnosti řečových technologií na základě měření signálové kvality a obsahové bohatosti audia / Estimation of accuracy of speech technologies based on signal quality and audio content richnessNezval, Jiří January 2020 (has links)
This thesis discusses theoretical analysis of the origin of speech, introduces applications of speech technologies and explains the contemporary approach to phonetical transcription of speech recordings. Furthermore, it describes the metrics of audio recordings quality assessment, which is split into two discrete classes. The first one groups signal quality metrics, while the other one groups content richness metrics. The first goal of the practical section is to create a statistical model for accuracy prediction of machine transcription of speech recordings based on a measurement of their quality. The second goal is to evaluate which partial metrics are the most essential for accuracy prediction of machine transcription.

Testování přesnosti mobilního laserového skenování / Testing of an Accuracy of Mobile Laser ScanningHoffmannová, Lada January 2020 (has links)
Diploma thesis describes collecting of data by mobile mapping system Riegl VMX-450. Science centre AdMas was captured with mobile mapping system. For the purpose of testing the accuracy, a calibration field was constructed in AdMaS. Main part of the thesis deals with testing of the accuracy of point cloud. Calibration field's coordinates were obtained by adjustment of the geodetic network using the least squares adjustment. During the testing, the coordinates of the calibration field points determined by the adjustment of the geodetic network and the coordinates of the points determined from the point cloud were compared. Another part of the work deals with testing of the accuracy, when target's position is in different height levels.

3D model vybraného objektu / 3D model of the selected objectMrůzek, Tomáš January 2021 (has links)
This diploma thesis describes the implementation of a 3D model of two objects using laser scanning. This paper deals with the accuracy evaluation of several data interpretation. The first two methods are the outputs of the results from the FARO SCENE program and other interpretations are the outputs from the TRIMBLE REAL WORKS program. To assess accuracy and veracity, the exact test field of points previously built in the AdMas complex was used. The result of the project is a georeferenced 3D model of two objects with the surrounding environment.

Srovnání přístrojových transformátorů proudu a proudových senzorů s ohledem na funkci rozdílové ochrany / Comparison of Instrument Transformers and Current Sensors with Respect to the Function of Differential ProtectionRajchman, Zbyněk January 2012 (has links)
Current transformers and current sensors are devices which are mostly used for current measurement in high voltage systems. These devices transform measured currents to range which are workable for measurement and protection devices. Theoretical part includes from third to seventh chapter. These chapters contain construction analysis and characteristic points for both device and problems of protecting the transformer with differential protection. Practical part includes from eighth to tenth chapter. This chapter consists results from laboratory measurement. Results are used for verification with theoretical part of the thesis. Conclusion of this thesis comparing properties and summarises results from laboratory measurement.

Testování jednotek Merging Unit v sestavě s proudovými a napěťovými převodníky / Testing of Merging Unit comprising voltage and current transducers in the setZiegler, Jiří January 2016 (has links)
The diploma thesis is focused on testing and design of a test system of merging unit which provides digital output according to IEC 61850-9-2. The parameters and distinguishing features of the test system are based on functional principles of merging unit and standards dealing with the testing of transducers. The proposed test system is based on modular PXI Express system from National Instruments. The desing is performed with respect to the possibility of generating test signals and measurements for voltage up to 38.4 kV and current up to 2000 A. The proposed test system meets the criteria for testing transducers of accuracy class up to 0.5. Assuming of calibration designed test system as a whole, this test setup has the potential to meet the technical requirements for testing transducers of accuracy class up to 0.1.
