Návrh parního generátoru pro modulární reaktor / Design of the steam generator for modular reactorČerný, Marian January 2012 (has links)
Subject of this thesis is design of the steam generator for modular reactor. The dissertation consist of the theoretical part, where are described heat-exchangers and steam generators used in nuclear power plants. Second part contains theoretical calculations in the first approach (thermal, hydraulic and strenght calculation). In the next part are particular variants of steam generator selected. For the final variant are necessary calculations (introduced above) and drawings of selected parts are done. In the final statement is technical solution evaluated, and the parameters of the steam generator are compared with actually used steam generators.

The Stixel WorldPfeiffer, David 31 August 2012 (has links)
Die Stixel-Welt ist eine neuartige und vielseitig einsetzbare Zwischenrepräsentation zur effizienten Beschreibung dreidimensionaler Szenen. Heutige stereobasierte Sehsysteme ermöglichen die Bestimmung einer Tiefenmessung für nahezu jeden Bildpunkt in Echtzeit. Das erlaubt zum einen die Anwendung neuer leistungsfähiger Algorithmen, doch gleichzeitig steigt die zu verarbeitende Datenmenge und der dadurch notwendig werdende Aufwand massiv an. Gerade im Hinblick auf die limitierte Rechenleistung jener Systeme, wie sie in der videobasierten Fahrerassistenz zum Einsatz kommen, ist dies eine große Herausforderung. Um dieses Problem zu lösen, bietet die Stixel-Welt eine generische Abstraktion der Rohdaten des Sensors. Jeder Stixel repräsentiert individuell einen Teil eines Objektes im Raum und segmentiert so die Umgebung in Freiraum und Objekte. Die Arbeit stellt die notwendigen Verfahren vor, um die Stixel-Welt mittels dynamischer Programmierung in einem einzigen globalen Optimierungsschritt in Echtzeit zu extrahieren. Dieser Prozess wird durch eine Vielzahl unterschiedlicher Annahmen über unsere von Menschenhand geschaffene Umgebung gestützt. Darauf aufbauend wird ein Kalmanfilter-basiertes Verfahren zur präzisen Bewegungsschätzung anderer Objekte vorgestellt. Die Arbeit stellt umfangreiche Bewertungen der zu erwartenden Leistungsfähigkeit aller vorgestellten Verfahren an. Dafür kommen sowohl vergleichende Ansätze als auch diverse Referenzsensoren, wie beispielsweise LIDAR, RADAR oder hochpräzise Inertialmesssysteme, zur Anwendung. Die Stixel-Welt ist eine extrem kompakte Abstraktion der dreidimensionalen Umgebung und bietet gleichzeitig einfachsten Zugriff auf alle essentiellen Informationen der Szene. Infolge dieser Arbeit war es möglich, die Effizienz vieler auf der Stixel-Welt aufbauender Algorithmen deutlich zu verbessern. / The Stixel World is a novel and versatile medium-level representation to efficiently bridge the gap between pixel-based processing and high-level vision. Modern stereo matching schemes allow to obtain a depth measurement for almost every pixel of an image in real-time, thus allowing the application of new and powerful algorithms. However, it also results in a large amount of measurement data that has to be processed and evaluated. With respect to vision-based driver assistance, these algorithms are executed on highly integrated low-power processing units that leave no room for algorithms with an intense calculation effort. At the same time, the growing number of independently executed vision tasks asks for new concepts to manage the resulting system complexity. These challenges are tackled by introducing a pre-processing step to extract all required information in advance. Each Stixel approximates a part of an object along with its distance and height. The Stixel World is computed in a single unified optimization scheme. Strong use is made of physically motivated a priori knowledge about our man-made three-dimensional environment. Relying on dynamic programming guarantees to extract the globally optimal segmentation for the entire scenario. Kalman filtering techniques are used to precisely estimate the motion state of all tracked objects. Particular emphasis is put on a thorough performance evaluation. Different comparative strategies are followed which include LIDAR, RADAR, and IMU reference sensors, manually created ground truth data, and real-world tests. Altogether, the Stixel World is ideally suited to serve as the basic building block for today''s increasingly complex vision systems. It is an extremely compact abstraction of the actual world giving access to the most essential information about the current scenario. Thanks to this thesis, the efficiency of subsequently executed vision algorithms and applications has improved significantly.

Modifikace materiálového toku zásobování výroby / Modification of material flow of the manufacturing suppliesHloušek, David January 2017 (has links)
The main content of this thesis is analysis and proposal of supplying between storages in company Hella Autotechnik Nova in Mohelnice. The main content of creation of this company is wide sort of front headlamps, rear and break lights, but also there is some sort of its washers for the most famous cars brands. Otherwise this thesis is about modification of basic layout, what can be seen there nowadays between external storage Meriva and logistic centre, what is located in main building of this company.
