Preklinické magneticko-rezonanční (MR) zobrazování na malých zvířatech je velmi aktuální a vyžaduje, vzhledem k rozměrům těchto zvířat, vyšší citlivost. Vyšší citlivosti lze dosáhnout použitím MR systému s vysokým základním magnetickým polem (např. 4,7 T a výše). Vyšší citlivost přináší výhody v podobě možnosti vyššího rozlišení, lepší poměr signál-šum, větší chemický posuv, prodloužení longitudinální relaxace (T1), atd. Na druhou stranu vyšší magnetické pole znamená větší deformace základního magnetického pole na rozhraních tkání s rozdílnou susceptibilitou a zkrácení transverzální relaxace (T2). Tuková tkáň je významně zastoupena v lidském těle a primárně sloužící pro uchovávání energie ve formě tuků. Tukovou tkáň lze rozdělit na hnědou a bílou tukovou tkáň. Hnědá tuková tkáň se vyskytuje hlavně u novorozenců, ale může být ve velmi malém množství také u dospělých jedinců. Bílá tuková tkáň je určena pro ukládání tuků, které slouží jako zdroj energie. Kromě toho bílá tuková tkáň produkuje adipokiny, hormony a mnoho dalších látek důležitých pro náš metabolizmus. Tuk lze obecně považovat jako biomarker při určitých nemocech (obezita, steatóza jater, a další). Z tohoto důvodu je kvantifikace tuku velmi důležitá pro správnou diagnózu. V MR zobrazování je speciální skupina metod pro separaci vody a tuku. Tyto metody se nazývají Dixonovy metody a jejich princip je založen na chemickém posuvu. V této práci je popsána nová T2-váhovaná sekvence pro Dixonovu akvizici (Kapitola 5.3). Navržená sekvence je z hlediska akviziční doby velmi efektivní a řadí se mezi tříbodové Dixonovy (3PD) techniky. Nově navržená sekvence fast triple spin echo Dixon (FTSED) vychází z původní sekvence rychlého spinového echa (FSE). Modifikací původní sekvence FSE vedla ke vzniku nové sekvence FTSED, která umožňuje získat tři obrazy během jediné akvizice, bez toho aniž bychom prodloužili celkovou dobu měření. Sekvence byla úspěšně implementována na 9,4 T MRI systém na Ústavu přístrojové techniky v Brně. Získaná data byla pak zpracována iterativně pomocí algoritmu IDEAL (iterative decomposition of water and fat with echo asymmetry and least-squares estimation). Výsledkem jsou separátní obrazy vody a tuků, z kterých lze vypočítat mapy frakce tuku (FF-mapy). Sekvence byla ověřena na fantomech a poté byla odzkoušena potkanovi. Úspěšná implementace této metody na 9,4 T MRI systému znamená, že může být použita také na MR zobrazovacích systémech s nižšími magnetickými poli.

This Thesis is focused on study of augmented reality and creation of algorithm for a uniform marker field detector. The marker field is modified to be tolerant to a high degree of deformation. Existing marker types are studied. Important part of the paper is a description of uniform marker field technique, from which a modified assignment is derived. It also describes CUDA architecture on which the first part of the detection algorithm is implemented. Deformation tolerance, detection rate and speed tests are performed on the resulting detector algorithm.

This master thesis deals with the realization of a simulator based on asynchronous cellular automata simulating delay insensitive circuits. In connection with nanotechnology, cellular automata have several interesting properties, such as self-replication, regular structure and high parallelism that make them very useful as models for some types of nanocomputers. This text describes the relationship between cellular automata and nanotechnology. Emphasis is given to the possibility of using asynchronous timing mode. Asynchronous cellular arrays based on asynchronous cellular automata could prove to be a suitable architecture for future nanocomputer, which was the reason for implementation of this simulator. The simulator's functionality was verified by experiments.

Sprinkled tube bundles with a thin liquid film flowing over them are used in various technology processes where it is necessary to separate the vapour and liquid phases quickly and efficiently. The process occurs predominantly at low temperatures with a corresponding decrease of pressure around the tube bundle. Such a technology is represented for instance by an evaporator at absorption units or an evaporator for sea water desalination. In ideal conditions water boils at the whole surface of an exchanger, but in practice it must be considered that in original spots of contact between water and the exchanger wall the water will not boil at the tubes' surface but the cooling liquid will merely be heated-up. The presented dissertation thesis focuses on this issue. The objective of the thesis was to determine the heat transfer coefficient at the surface of sprinkled tube bundles of various geometries at atmospheric pressure as well as low pressure. For this purpose experiments have been carried out at tube bundles consisting of copper tubes of 12,0 mm diameter placed horizontally one above another that were heated by water. Three types of tubes (smooth, sandblasted and grooved) of four various pitches (15,0 to 30,0 mm by 5,0 mm increments) have been tested. Simultaneously individual bundles' geometries consisted of 4, 6, 8 and 10 tubes with identical surface finish. Based on the conducted experiments the mathematical model of heat transfer that involves mainly analogy criteria has been made more accurate. A temperature field at the sprinkled tube bundle surface has been scanned by a thermographic camera during the performed experiments. Influence of geometry and tube surface finish on flow mode and consequently also on heat transfer has been assessed in accordance with the compiled methodology.

The aim of this thesis is to simulate the action of electrodynamic forces on current carrying path and a movable contact of the circuit breaker OEZ Modeion BH 630NE. For the calculation there is used the simulation program Ansys Maxwell. The first part is devoted to theoretical analysis of electromagnetic forces on a conductor in a magnetic field. Further I discuss the constructional design of the circuit breaker itself, especially the current path and the contact mechanism. In the next part there is (with using program Autodesk Inventor) created a simplified 3D model of the current path including an arc chamber. With program Ansys Maxwell then there is performed simulation of the acting of forces in each mode. This is magnetostatic and transient analysis for symmetrical and asymmetrical flow of the fault current. In conclusion the results obtained are evaluated and processed in the tabular way.

This master thesis deals with determination of boundaries of the flow from a benchmark automotive vent (right-front situated – in front of a front passenger) using the smoke visualization. In this thesis is tested a pack of eight different constructional variants which differ among them by the type of deflection grille. The angles of the flow borders are compared to specific directional requirements (defined by ŠKODA AUTO a.s.) and there is evaluated a directability of each of the constructional variant on the bases of these results. The results of experiments show that better directability in vertical plane achieve deflection grilles with horizontal vanes situated closer to orifice of the vent or deflection grilles with higher number of horizontal vanes and lower number of vertical vanes (independently of their location). Directability of the deflection grilles in horizontal plane is analogically better with vertical vanes situated closer to orifice of the vent or with deflection grilles with higher number of vertical vanes and lower number of horizontal vanes (independently of their location).
