USE OF AUTOMATIC COLLECTION OF GROUND CONTROL POINTS FOR ORIENTATION OF ARCHIVAL AERIAL IMAGERY USING EXISTING DATA SETS
Berka, Rostislav ; Potůčková, Markéta (advisor) ; Dušánek, Petr (referee)
USE OF AUTOMATIC COLLECTION OF GROUND CONTROL POINTS FOR ORIENTATION OF ARCHIVAL AERIAL IMAGERY USING EXISTING DATA SETS Abstract The diploma thesis is focused on the automated searching of ground control points (GCPs) for processing archival aerial images (AAIs) and creating orthomosaics. The study evaluates selected computer vision operators (SIFT, SURF, ORB and image correlation) and various approaches for identifying and subsequently matching identical points between the reference dataset (current orthophoto) and AAIs. Thanks to AAIs georeferences, the searching area in AAI is known for finding the corresponding point to the reference one (from current orthophoto). Unfortunately, the georeferencing of AAIs provided by the Czech Office for Surveying, Mapping, and Cadastre (ČÚZK) was methodologically incorrect (very bad accuracy) and it had to be corrected before automated GCPs searching. The topic was supported by ČÚZK and datasets (current orthophoto, AAIs, ZABAGED vector data) were provided for processing purposes free of charge (beyond the standard student license). Based on operator testing, a fully automated methodology was developed in Python, relying on image correlation. The input includes AAIs, current orthophoto and a road network, with road intersections as reliable and time invariant points....

Assessing Economic Situation of a Company and Proposals for Its Improvement
Hynek, Jan Jaroslav ; Franková, Tereza (referee) ; Doubravský, Karel (advisor)
The master’s thesis deals with the assessment of the financial situation of XZY s.r.o. using financial analysis and statistical methods. The theoretical part is divided into financial and statistical theory. In these parts, it presents the definition of selected financial ratios and statistical methods, which include time series regression and correlation analysis. The theoretical part is followed by an analytical part in which the financial situation of the selected company is evaluated along with the prediction of selected ratios. Furthermore, the selected ratios are subjected to correlation analysis where the interdependence between them is examined. The paper concludes with suggestions for improving the financial situation of the enterprise.

Assessing Economic Situation of a Company and Proposals for Its Improvement
Rýpal, Matěj ; Novotná, Veronika (referee) ; Doubravský, Karel (advisor)
This thesis focuses on the evaluation of the economic situation of the company GUMEX, spol. s.r.o. and the prediction of future development using statistical methods. The theoretical part of the thesis deals with the description of selected financial ratios and statistical methods such as time series analysis, regression and correlation analysis. In the practical part, the individual ratios are calculated to assess the financial condition of the analysed company and the selected ratios are then analysed using statistical methods to predict future developments. The final part of the thesis is devoted to the proposals based on the results of the analytical part of the thesis and aimed at improving the financial situation of the company.

Analysis of economic data using statistical methods
Pavlásek, Boris ; Doubravský, Karel (referee) ; Michalíková, Eva (advisor)
This bachelor thesis deals with the analysis of the economic data of a company and the subsequent evaluation of its financial situation. In doing so, it uses the tools of financial analysis and statistical methods, namely regression analysis and time series. The theoretical part presents the theory needed to perform the analysis and also explains different financial indicators, statistical methods and regression functions. In the analytical part, data from the company's financial statements are used for financial analysis and subsequent forecasting of their future progress. In the last parts of the thesis, a comprehensive assessment of the financial situation of the company and suggestions for solving the identified problems are presented.

Time Series Forecasting Using Maching Learning for Network Communication
Kašpárek, Aleš ; Burgetová, Ivana (referee) ; Matoušek, Petr (advisor)
Tato diplomová práce zkoumá komplexní svět síťových komunikačních systémů, které vyžadují pokročilé metody předpovědi, aby fungovaly efektivně, spolehlivě a bezpečně. Se sítěmi stále složitější, přesné předvídání podmínek sítě a jejího provozu je rozhodující pro plánování, řízení zdrojů, detekci anomálií a zlepšování systémů. Práce začíná představením konceptu časových řad dat, který pokládá základ pro pochopení dynamiky v síťových systémech. Pokračuje tím, že představuje řadu analytických nástrojů a technik pro rozbor tohoto druhu dat, se zvláštním zaměřením na tradiční statistické metody. Mezi nimi je modelům Moving Average (MA), Auto Regressive (AR) a Auto Regresive Integrated Moving Average (ARIMA) věnována zvláštní pozornost pro své schopnosti v předpovídání budoucích stavů. Posun od tradičního předpovídání k používání strojového učení (ML) je ústředním bodem této práce. Práce zkoumá několik přístupů strojového učení (ML), jako jsou sítě Long Short-Term Memory (LSTM), konvoluční neuronové sítě (CNN), aby ukázala, jak mohou tyto metody identifikovat složité vzorce v síťovém provozu.

This diploma thesis focuses on the assessment of the economic situation of XYZ Med s.r.o. for the period from 2013 to 2022. The economic situation of the company is evaluated on the basis of selected financial indicators, which are then subjected to statistical analysis in order to create a basis for the proposal of measures to improve the situation. The theoretical part describes the financial ratios, correlation analysis, regression analysis and time series. In the analytical part of the thesis, the calculation of financial ratios is performed and then a statistical analysis is carried out on the basis of which the future development of the company is predicted. The analysis also tests the dependence for selected ratios. The practical part contains suggestions for improving the economic situation of the company.
