Set-off Defence
Vaněk, Martin ; Dvořák, Bohumil (advisor) ; Holčapek, Tomáš (referee)
63 Set-off Defence Abstract The thesis deals with set-off from the point of view of procedural law and using the method of functional interpretation of law, strives to provide answers to questions that appear in the court proceedings in connection with its use. It builds on theorists who dealt with the issue of inducing an effect of set-off in the proceedings in the late 20th century, but also takes into account the findings of current academic community and presents the judicial conclusions reached by (not only Czech) courts. The thesis is divided into 4 chapters. The first chapter briefly deals with the substantive legislation of set-off (especially the requirements laid down for the receivables that are to be set-off, and cases where set-off is prohibited by law). A declaration of set-off as a substantive act may be decisive in assessing the admissibility of set-off in proceedings. The second chapter describes the origin of set-off in ancient Rome and the different concepts of set-off in current legal codifications, which is the result of inconsistent interpretation and reception of this institute by medieval scholars. This is reflected by Czech legal science in existence of civilian and procedural theory of offsetting. In the third chapter, the thesis deals with purely procedural aspects of set-off. The...

Thesis describes machines and mechanical lines for the processing of wood waste - chippers. The teoretical part reports about chippers and their ulitization. Thesis introduces basic division of chippers with presentation of basic types of crushing devices. Czech and foreign producers are presented with their produced types of machines. At the end of the teoretical part are described individually machines and machinal lines with complete work process. This process is used for felling and following disposal of wood mass in wood lands and in cities. In the practical part thesis compares desinged machine sets in field laboratory mensuration. Measured values were compared. Costs and economical aspects of the compared machine lines are quantified in the end.

Vaněk, Martin
The diploma thesis deals with the definition and characteristics of decisive factors that influenced the production and economic context of the development of the individual phases of the commodity vertical sugar - sugar beet in the Czech Republic and within the EU common market. It defines in more detail the crucial changes affecting the business environment related to sugar beet and sugar production. It characterizes the impacts of specific measures on individual phases of commodity vertical. It examines the development of sowing areas, yield per hectare and sugar content of sugar beet for agricultural producers. Within the downstream industry, it describes the development of our sugar industry and compares current processing capacities with selected EU countries. In conclusion, the thesis deals with the balance of import and export of sugar and confectionery, as well as the analysis of the relationship between price and sugar consumption and the reaction to price movements in individual phases of commodity vertical.
Photopolymerization kinetics of dimethacrylate dental resin
Vaněk, Martin ; Bystřický, Zdeněk (referee) ; Poláček, Petr (advisor)
Aim of magister´s thesis was to study reaction kinetics of dental materials. Thesis was focused on dimethacrylate dental polymers, which are for example used for dental restoration, tooth repair and creating now teeth. First part of the thesis concentrates on influence of molar ratio on reation kinetics by addition of other monomer to polymer resin. Second part concentrates on influence of addition of additive silica on reaction kinetics of polymerization. Essential variables know as a polymerization ratio, conversion, gel point, glass transition temperature and storage modulus were studied. Firstly, polymerization ratio and conversion were observed by differential scanning calorimetry (DSC). Secondly rheology was observed by photoreometr. Finally, glass transition temperature and storage modulus were observed by dynamic mechanical analysis (DMA). Behaviour changes caused by addion of monomer or filler point out decrease of polymeration ratio and converstion. Same behaviour was observed by short exposure. In order to established network formation, values of gel point increased by higher concentration of monomer or filler. Glass transition temperature and storage modulus measured by DMA were evaluated. Those valuables had variable tendency due to monomer acting like filler at higher concentration. Also contradictory impact of different material conversion and filler concetration was discussed.
Porovnání zpracování půdy s využitím a bez použití GPS technologie
VANĚK, Martin
This bachelor thesis deals with the comparison of the operational and economic parameters of operation of a selected vehicle used for tillage. The bachelor thesis is divided into two main parts, theoretical and practical. The theoretical part provides an introduction to satellite navigation, describes the most important navigation systems, the structure of the GPS system and basic principles of its operation. The theoretical part also deals with the use of GPS navigation in current agricultural machinery and precision agriculture. The practical part compares the use of manual control and guidance by GPS navigation in soil processing.
Image compression simultaneously in spatial and frequency domains
Vaněk, Martin ; Šorel, Michal (referee) ; Rajmic, Pavel (advisor)
This thesis is concerned with image compression. Firstly, JPEG lossy compression and origin of typical artifacts is explained. Then, some basic concepts are introduced and sparse representation of signals are presented. Then presentation of proximal algorithms is folowed and formulation of two optimazation problems, wchich removes typical artifacts on edges, created by JPEG compression. These problems are then solved by proximal algorithms.

Study of carotenogenic yeasts doring growth by using advanced instrumental techniques
Vaněk, Martin ; Breierová, Emília (referee) ; Márová, Ivana (advisor)
This work is dealing with application of advanced fluorescence techniques for gaining knowledge about culture development during fermentation of red yeasts. Flow cytometry was used for auto-fluorescence measurement a carotenoids quantitation. It was resolved that while carotenoids are stored mainly in membranes the technique was feasible. If red yeast starts to accumulate carotenoids into lipid bodies mainly throughout the course of stationary phase, then the method starts to fail. Flow cytometric method using cell size measurement and light scatter for lipid quantitation was proved as applicable, too. However, it works only if cells are not starved. Individual calibration for each species is needed for elimination inter-species variations of intracellular structures. Fluorescence lifetime imaging microscopy was also used for studying of red yeast. Inherent ability to resolve different fluorescent species of the same molecule, which arise due to different molecular environment, helps with quantitation of cellular lipidic structures changes through the course of fermentation. Increase in the levels of carotenoids and/or rigidity of membranes was found as mechanism of protection during metabolic shifts, when intracellular content is vulnerable to damage.

Hlavním cílem této práce je charakterizace vzorků titanátů, jako materiálů pro sodíko-iontové (Na-ion) akumulátory. Syntéza některých vzorků je součástí této práce. Charakterizace je zaměřena na elektrochemické vlastnosti, složení a morfologii použitých materiálů. První část se zabývá lithium-iontovými (Li-ion) akumulátory. Byly vybrány, protože jsou ve vědeckých článcích dobře popsány a základní funkční princip je aplikovatelný také na Na-ion akumulátory. Materiály používáné pro katody, anody a elektrolyty následují po krátké části shrnující parametry a konstrukci Li-ion akumulátorů. Následující kapitola je zaměřena na sodíko-iontové akumulátory. Srovnání sodíku a lithia je následováno materiály používanými pro elektrody a elektrolyty (s důrazem na anodové materiály). Třetí část popisuje analytické metody použité pro charakterizaci elektrod a materiálů. Jedná se o elektrochemickou charakterizaci (cyklická voltametrie a galvanostatické cyklování s potenciálovým omezením), morfologii (rastrovací elektronová mikroskopie) a složení (X-ray difrakční spektroskopie). Poslední dvě kapitoly obsahují syntézu a charakterizaci sodného titanátu a charakterizaci dvou vzorků TiO2. Výsledky této práce jsou shrnuty v závěru.
