New procedures for evaluating concrete in existing construction
Juřenová, Jana ; Kocáb, Dalibor (referee) ; Cikrle, Petr (advisor)
This bachelor thesis seeks to increase the awareness of the possibility of using the ultrasonic pulse method for the diagnosis of building structures. It emphasises the use of non-destructive methods, highlighting their ability to provide comparable results to traditional destructive methods of assessment, whilst minimising interference to the structure. The work includes reporting on the procedures for determining the characteristic compressive strength of concrete in existing structures as defined in EN 13791, updated in 2021. The work focuses primarily on calibrating results from non-destructive indirect measurements with those obtained destructively using core borings.

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
Červinek, František ; Bezeli, Miroslav (referee) ; Doubravský, Karel (advisor)
The master's thesis analyzes the economic situation of the company PARDOSA – technik, s.r.o. using selected financial indicators and statistical methods. The thesis is divided into three parts. The first part describes the theoretical background of financial analysis, economic indicators, time series, correlation and regression analysis. In the second part, the analyzed company is briefly introduced first, and then calculations of selected financial indicators are performed along with their verbal evaluation and graphical representation. Based on the results of the analytical part, I will present suggestions and recommendations that should lead to the improvement of the economic situation of the analyzed company.

Assessing Economic Situation of a Company and Proposals for Its Improvement
Rybár, Tomáš ; Novotná, Veronika (referee) ; Doubravský, Karel (advisor)
The diploma thesis focuses on the assessment of the economic situation of Prefa Brno a.s. and possible suggestions for improving its performance. The theoretical part of the thesis is devoted to the explanation of the concepts of financial and statistical analysis. These concepts are then applied in the analytical part. From the financial analysis, the difference and ratio indicators are evaluated, supplemented by a set of indicators. Regression analysis is performed on selected ratios with a forecast for the following period and correlation analysis is used to identify the interrelationships between them. Conclusions are drawn from the results, which are used to formulate possible measures to improve the current economic situation of the entity under study.

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.

Exploring correlation between vegetation indices and plant nitrogen uptake
Pavlačková, Alena ; Doležalová Weissmannová, Helena (referee) ; Kučerík, Jiří (advisor)
Nadměrné hnojení může způsobit znečištění životního prostředí, jako je kontaminace vody a emise skleníkových plynů, a také ekonomické ztráty. Ke zmírnění těchto problémů je důležité přizpůsobit míru hnojení specifickým potřebám plodin. Ve své práci se zabývám možností využití dálkově snímaných vegetačních indexů pro monitorování příjmu dusíku rostlinami a řízení aplikace hnojiv. Měření byla provedena v Oensingenu, Švýcarsku, během stáže na ETH Zürich. Hlavním cílem bylo vyvinout predikční model založený na vegetačních indexech k odhadu příjmu dusíku travní směsi a ozimé pšenice. Dále byla analyzována korelace mezi různými vegetačními indexy a charakteristikami plodin, především příjmu dusíku. Vegetační indexy (NDVI, NDRE, GNDVI, MCARI, EVI) byly získány ze snímků družice Sentinel-2 pomocí Google Earth Engine. Byly změřeny různé charakteristiky plodin, včetně indexu listové plochy (LAI) a výšky plodin, a vzorky ozimé pšenice byly analyzovány na příjem dusíku pomocí elementárního analyzátoru. Do analýzy byla také zahrnuta další data týkající se příjmu dusíku travin z předchozích let. Celkem byla v analýze použita data z let 2021–2023, která zahrnovala hodnoty pro travní směs i ozimou pšenici. Byly provedeny korelační a regresní analýzy k určení vztahů mezi vegetačními indexy a měřenými charakteristikami plodin. Index, který vykazoval nejsilnější vztah s příjmem dusíku plodin, byl poté využit k vytvoření predikčního modelu. Analýza ukázala, že Enhanced Vegetation Index (EVI) byl nejúčinnějším prediktorem příjmu dusíku. Vytvořený predikční model založený na hodnotách EVI dosáhl vysokého koeficientu determinace (R$^2$) 0,89, nízké směrodatné odchylky chyb (RMSE) 1,05 a průměrné absolutní odchylky (MAE) 0,89. Výsledky naznačují, že EVI je spolehlivým indexem pro predikci příjmu dusíku plodinami. Vyvinutý model založený na EVI by mohl být potenciálně použit k optimalizaci aplikace dusíkatých hnojiv na plodiny, což by pomohlo snížit negativní environmentální a ekonomické dopady nadměrného hnojení.

Human Hand Geometric Parameters Measurement Using Numerical Methods of Image Processing
Vanžurová, Anna ; Procházková, Jana (referee) ; Štarha, Pavel (advisor)
This thesis deals with a matematic model used for estimation of the surface of a human hand. By using the theory for digital image processing, analytic geometry and numerical methods a model for proccesing a photografy of a hand was created. This model further calculates the surface in the software Matlab. The model uses tools such as median filter, adaptive tresholding or conditional erosion. Interesting is the usage of the curvature of a curve, which can be used to find the peaks and bases on the border of the hand. Dependencies between the calculated results and the measured real surfaces can be found. Therefore a regression function could be found, which gives us a point estimation of the human hand surface.
