Using Time Series Analysis to Evaluate Company Efficiency
Sedmera, Tomáš ; Málek, Miroslav (referee) ; Doubravský, Karel (advisor)
The thesis focuses on assessing economic health of Agro Zvole, a.s. company, operating in the agricultural sector, producing plant and animal production. For objective evaluation of economic performance financial analysis indicators are used, to also work with statistics, represented by timeline analysis technique. Both previous numerical procedures (methodology) are based on company financial statements for each fiscal period. To be specific, individual indicators of financial analysis from the financial statements (profit and loss account and balance sheet) are calculated for each fiscal period and these are then aligned using time lines and future trends prediction (development). The individual results are accompanied by commentaries. To create the right comments, resulting from arithmetic operations, it is useful to compare individual results with management of other corporate entities within a single sector of the economy and their respective area. That is why other agricultural companies from former Žďár nad Sázavou district are included in the research as they follow: Agria Ujčov, a.s., Bobrovská, a.s. and Bohuňov Company, a.s. Previous research conclusions based on results of comparing the management of Agro Zvole, a.s. with managements of other companies are used to discover gaps of Agro Zvole, a.s. management. Next section of the thesis is devoted to model my own proposals to eliminate or at least alleviate problematic conditions in the company's performance. It is important to find mistakes, but more importantly find a way to eliminate them. In conclusion, the thesis summarizes the results of each part of the work and its benefits are outlined for the referenced entity.

Sheepfarm
Lazarová, Táňa ; Kunc, Petr (referee) ; Myslín, Jiří (advisor) ; Skála, Jiří (advisor)
The thesis is dedicated to a complex of a sheep farm, pension and restaurant lying by the Pozďatín village. The concept is aimed on simplicity, functionality and sensible placement into countryside. The farm is directed to the road to the village, and pension and restaurant are oriented to the forest and Ostrovec lake. Both buildings have single floor, and have longitudinal shape, which cross-section resembles half-ellipsis. The objects are complemented by slightly unhung and rectangular passages, entrances, and windows. The facade is made from horizontal wooden siding, which contrasts with sheet metal paneling of entrances and windows.

Design of Light Agricultural Tractor
Oulehla, Jakub ; Chorý, Tomáš (referee) ; Křenek, Ladislav (advisor)
The subject of this diploma is the design of a versatile light agricultural tractor. The design of the tractor will focus on timeless design. The proposed tractor will also differ from the current competition in the field of light agricultural tractors. The resulting tractor will also be usable outside agriculture, in horticulture or communal services.

Jaroslavice – place in the landscape
Mrlinová, Lucie ; Veselá, Markéta (referee) ; Foretník, Jan (advisor)
South Moravia has a good quality soil. Changing climatic conditions and an unhealthy human approach result in drought and soil erosion. Soil, like our nutritionist, is very rare. Therefore, in my work I deal with the proposal of a research institute for soil protection, which I place on the site of a former manor court in Jaroslavice. The Institute consists of three buildings that define a common yard. The location of the complex complies with the direct connection to the adjacent experimental field. Jaroslavice, as a municipality in the warmest and driest area in the Czech Republic, is ideal for research.

Fusion of Radar and Visual Data for Remote Sensing
Strych, Tomáš ; Beran, Vítězslav (referee) ; Kolář, Martin (advisor)
Cieľom práce je vygenerovať satelitný optický snímok v prípade jeho nedostupnosti. Takýto snímok je vygenerovaný z aktuálneho radarového snímku a za pomoci radarových a optických snímkov z minulosti. Zameranie práce cieli na poľnohospodárstvo, kde sa na analýzu dát používajú rôzne vegetačné indexy. Pre zjednodušenie problematiky je práca zameraná len na optický snímok zobrazujúci NDVI. Boli vytvorené 4 dátové sady, pre prvé tri ročné obdobia a~štvrtý, ktorý ich spája. Pre riešenie problému preloženia obrázku z jedného na druhý bol použitý model Pix2Pix-cGAN. Výsledky práce zobrazujú rozdiely pri použití dátových sád, rozličného množstva a~typu použitých snímkov, tak ako aj intervalu medzi snímkami. Daným výskumom bolo zistené, že sieť je schopná vytvárať reálne uveriteľné obrázky s validnými numerickými hodnotami, avšak má problém správne využiť informáciu o radarovej zmene, ktorá je dôležitá pre ohodnotenie vývoja rastlín práve v prípade nedostupnosti optického snímku. Táto práca a~jej výsledky sú jedinečné vďaka naprieč Európou geograficky rozmanitej dátovej sade a vďaka zameraniu na agrikultúru, a to bez ohľadu na typ plodín.

Nitrate removal from agricultural runoff
Schrimpelová, Kateřina ; Šálek,, JAN (referee) ; Drtil,, Miloslav (referee) ; Malá, Jitka (advisor)
The increasing concentration of nitrates in surface water and groundwater is becoming a global problem. The dissertation thesis is focused on the denitrifying bioreactors with organic fill material designed for the reduction of nitrate input from agricultural areas in the Czech Republic. A set of laboratory experiments was performed – static leaching tests and column tests, including chemical analyses of outflow water and ecotoxicological bioassays. Seven materials common in the Czech Republic, various process parameters, types and lengths of bioreactor shutdown in dry periods and the use of outflow water for irrigation were tested. The thesis deals with both denitrification efficiency and ways of reducing negative effects. An evaluation of the overall effect bioreactors is included along with a prediction regarding leaching over the following years.

Simple agrocontroller
Pelikán, Michal ; Friedl, Martin (referee) ; Steinbauer, Miloslav (advisor)
Simple agrocontroller is a realization of control computer of spray machine in agriculture technique. Introduction describes the types of individual sprayers and their main differences. Hydraulic scheme displays the layout of regulators, ventils, hosepipes etc. Chapter Requirements defines needed functions and variables. Next chapter explains the structure of the layout of agrocontroller´s individual parts. Also defines required functions and features of these parts with real circuits and components and methods of gaining required values. Practical part show how printed circuits boards look like and what are features and properities of agrocontroller.
