Dávkový automatický korektor pravopisu slov rozsáhlých textových souborů

Péchal, Martin January 2014 (has links)
This thesis is about spell checking. The main goal is to design an automatic spell checker which can find misspellings in text and correct them without any additional user input. The spell checker must be also able to correct huge amount of text data because it will be used for pre-processing of text before some data mining methods will be applied.

Detekcia a korekcia typografických jevov v značkovanom texte

Makeš, Dominik January 2015 (has links)
In this thesis, I am dealing with an design and implementation of finite deterministic automaton. Its role is to process the ConTeXt input file and make a decision about its typography correctness. In next step, it will offer the recommendation how to correct the mistake and will be able to make simple automatic correction. Thesis is also including the comparision with existing programs and the tests on real documents. Thesis is also including theoretical subscription of formal languages and finite automaton.

Statistická korekce denních srážkových úhrnů z klimatických modelů / Statistical correction of daily precipitation sums from climate models

Hnilica, Jan January 2016 (has links)
Climate change prediction and evaluation of its impact currently represent one of the key challenges for the science community. Regional climate models (RCM) have been recently established as a main source of the data for climate change assessment studies. Nevertheless, RCM outputs suffer from systematic errors caused primarily by their low spatial resolution and cannot be used directly without any form of bias correction. The bias correction is an actual topic in climatology and several correction methods were developed, ranging from the simple additive method to more advanced approaches (e.g. quantile mapping). However, despite this progress, the bias correction methods suffer from several difficulties, which bring another source of uncertainty into the climate change impact assessment studies. This thesis is focused on two problematic points connected with the bias correction of daily precipitation data. The first one is a non-stationarity between calibration and application periods. New correction methods are developed, showing an increased resistance to non-stationary conditions. The second problem is related to the correction of a dependence (i.e. correlation and covariance) structure of multivariate precipitation data. A new procedure is proposed, correcting the complete dependence structure of the model data. All newly introduced methods are validated using measured and RCM-simulated data; the validation demonstrates their suitable applicability.

Korekce a kompenzace při měření teplot / Correction and Compensation in Temperature Measurement

Zábranský, Jaroslav January 2009 (has links)
The temperature belongs to the one of the basic values for a commercial measuring processes. The exact measuring of the temperature is the essential for a multitude manufacturing procedures and their regulations. This study is mainly focused to determine what influences can take the negative effect to exact temperature measurement. Content: List of of possible mistakes and their compensation wit the special focus on a notorious and frequent dynamic errors. Characteristic of those dynamic properties are important to analyze all the possibilities to correct different measuring systems. In this study we also present the simple model to deal with some error corrections

Factors affecting economic growth in Serbia

Papić, Danijela January 2019 (has links)
This diploma thesis evaluates the impact of selected factors on economic growth in Serbia. The existence of the relationship between economic growth and chosen macroeconomic indicators is tested with the use of cointegration test, Vector Error Correction model (VECM) and Granger causality test during the period 2007-2017. When it comes to long-run dynamics, results show positive impact of inflation, while the exports have negative influence. In the short-run, positive effect is observed by inflation and exports and negative by FDI. No effect of government expenditures is revealed in both short-run and long-run.

Rozvoj tenisové techniky / Development of tennis technique

Velebil, Matěj January 2021 (has links)
Title: Development of tennis technique Objectives: The main object of this thesis is to analyse the fundamental factors that affect the development of tennis technique. Furthermore, this thesis presents the most common deviations from the optimal tennis technique, including their possible causes, and consequently suggests possible corrections that would help optimise the technique. Methods: Based on the analysis of documents, are present the fundamental factors that influence tennis technique. Specific selected deviations are develop from the optimal tennis technique on the parts of the basic strokes, in which the specific deviations, its description and the causes are stated. Furthermore, methods of correction to eliminate the mentioned technical deviations are proposed. This methods are based on the analysis of documents and observations from our own past experience. Results: The result is a detailed analysis of factors that affect the development of tennis technique. Furthermore, a list of deviations from the optimal technique with possible causes and proposed methods of their possible correction. The theoretical basis of the work deals with tennis technique as a fundamental factor influencing sports performance in tennis. Keywords: Biomechanics, exercises, correction, deviation, stroke

Hodnocení časových řad družicových snímků k pozorování disturbancí v oblasti Nízkých Tater / Evalution of Time Series of Satellite Images to Observe Disturbancec in the Low Tatras

Laštovička, Josef January 2016 (has links)
The work is aimed at finding appropriate methods for observing changes in the status of forest vegetation and its evaluation in the years 1992-2015. The satellite images of the Low Tatras are analyzed by using Time Series technology. Specifically, the images Landsat 4, 5, 7 and 8, for which it is necessary to perform a calibration and an adjustment of input data values to realize the individual vegetation indices, due to the fact that the images are captured by different sensors with different radiometric resolution. From this perspective, the work deals with the possibilities of normalized relative radiometric corrections and search for a particular type of appropriate compensation for Landsat CDR images. Calibrated data sets are evaluated by Time Series of different vegetation indices. The resulting values are evaluated in relation with the occurrence of forest disturbances, eg. wind storms, biological and other pests. The final part is discussion of the results, evaluating the test methods of calibration and suitability of vegetation indices for observing the state of calamity. The App is created for generating the Time Series of Landsat images CDR and for preparing RRN datasets. Key words: Time Series, radiometric correction, atmospheric correction, Landsat CDR, vegetation indices,...

Aerodynamika axiálních větrných turbín / Aerodynamics of axial wind turbines

Just, Jan January 2013 (has links)
This master thesis concerns about problematics of wind turbines. The document summarizes basic theory based on the law of momentum conservation which is essential tool for the design and calculation of wind turbines. The theory is complemented by number of correction factors and then used in the design of wind turbine for specific parameters. The calculation is performed iteratively using Matlab software and the actual code is given in appendix. Graphs summarizing the progress of various units along the blades are presented in the document. The final section briefly describes advanced topics of aerodynamics concerning other important factors that the field of wind energy deal with in recent time.

Polarizace vakua v Coulombickém poli / Polarizace vakua v Coulombickém poli

Šimsa, Daniel January 2013 (has links)
In the present work the vacuum polarization and the circular dichroism of hydrogen-like atoms are studied. We derive equations for the Fourier transforma- tion of the vacuum expectation value of the charge density. We use it to derive Uehling potential and calculate energy shifts caused by it. Then we discuss effects of vacuum polarization in higher orders of α. In second part we define circular dichroism and we express it in terms of reduced matrix elements. Then we derive the formula for parity vilating potential which is generated by weak interaction and together with other results we use it to find the expression for circular dichro- ism in terms of hydrogen radial functions. 1
