The Semantic Web is the vision of the future Web. Its aim is to enable machines to process Web documents in a way that makes it possible for the computer software to "understand" the meaning of the document contents. Each document on the Semantic Web is to be enriched with meta-data that express the semantics of its contents. Many infrastructures, technologies and standards have been developed and have proven their theoretical use for the Semantic Web, yet very few applications have been created. Most of the current Semantic Web applications were developed for research purposes. This project investigates the major factors restricting the wide spread of Semantic Web applications. We identify the two most important requirements for a successful implementation as the automatic production of the semantically annotated document, and the creation and maintenance of semantic based knowledge base. This research proposes a framework for Semantic Web implementation based on context-oriented controlled automatic Annotation; for short, we called the framework the Semantic Web Implementation Framework (SWIF) and the system that implements this framework the Semantic Web Implementation System (SWIS). The proposed architecture provides for a Semantic Web implementation of stand-alone websites that automatically annotates Web pages before being uploaded to the Intranet or Internet, and maintains persistent storage of Resource Description Framework (RDF) data for both the domain memory, denoted by Control Knowledge, and the meta-data of the Web site's pages. We believe that the presented implementation of the major parts of SWIS introduce a competitive system with current state of art Annotation tools and knowledge management systems; this is because it handles input documents in the ii context in which they are created in addition to the automatic learning and verification of knowledge using only the available computerized corporate databases. In this work, we introduce the concept of Control Knowledge (CK) that represents the application's domain memory and use it to verify the extracted knowledge. Learning is based on the number of occurrences of the same piece of information in different documents. We introduce the concept of Verifiability in the context of Annotation by comparing the extracted text's meaning with the information in the CK and the use of the proposed database table Verifiability_Tab. We use the linguistic concept Thematic Role in investigating and identifying the correct meaning of words in text documents, this helps correct relation extraction. The verb lexicon used contains the argument structure of each verb together with the thematic structure of the arguments. We also introduce a new method to chunk conjoined statements and identify the missing subject of the produced clauses. We use the semantic class of verbs that relates a list of verbs to a single property in the ontology, which helps in disambiguating the verb in the input text to enable better information extraction and Annotation. Consequently we propose the following definition for the annotated document or what is sometimes called the 'Intelligent Document' 'The Intelligent Document is the document that clearly expresses its syntax and semantics for human use and software automation'. This work introduces a promising improvement to the quality of the automatically generated annotated document and the quality of the automatically extracted information in the knowledge base. Our approach in the area of using Semantic Web iii technology opens new opportunities for diverse areas of applications. E-Learning applications can be greatly improved and become more effective.

Les travaux menés durant cette thèse s'intéressent principalement aux avantages que peut offrir la machine asynchrone à double alimentation (MADA) dans un système de propulsion navale. Ceci est obtenu à travers les degrés de libertés additionnels qu'elle apporte, d'une part, par l'exploitation de la redondance structurelle naturelle, et d'autre part , par les stratégies de contrôle qui lui sont appliquées. La première partie de ce mémoire, présente la modélisation du propulseur innovant. Ce dernier est conçu principalement autour de la MADA comme moteur de propulsion. Il est alimenté par deux onduleurs de tension à Modulation de Largeur d'Impulsion (MLI), et entrainant une hélice à trois pales fixes et symétriques. Plusieurs stratégies de commande ont été introduites pour piloter le système. En effet, des lois de contrôle de type linéaires et non linéaires, associées à des divers modulateurs MLI ont été validées et appliquées à cette structure de propulsion. L'innovation apportée dans le cadre de ces travaux consiste à associer à l'optimisation par conception (machine et convertisseurs d'alimentation), une optimisation par la commande et ce en évaluant l'influence de ces techniques pour deux critères de dimensionnement majeurs, à savoir, les pertes dans les convertisseurs de puissances, et les bruits acoustiques et vibratoires. La propulsion navale, comme tout système embarqué, possède des exigences en matière de qualité de service non seulement en termes de performances mais aussi de fiabilité et de disponibilité. En effet, les systèmes conçus pour ce type d'application doivent assurer et garantir une continuité de service en cas d'apparition de défauts au sein des constituants du système. L'utilisation de la MADA dans les systèmes de propulsion offre une redondance structurelle naturelle et analytique, introduite par la commande, qui permet d'assurer une continuité de service du système en présence d'une défaillance dans la structure. Deux défauts sont ainsi considérés dans cette étude, un défaut de semi-conducteur de puissance dans le convertisseur de puissance et un défaut de capteur vitesse/position. Les stratégies de contrôle proposées, les modèles de propulseur établis ainsi que les reconfigurations adoptées suite aux défauts ont été validées expérimentalement sur les bancs développés au LAPLACE dans le cadre de ces travaux. / This study focuses on the benefits that can be induced by the use of the Double Fed Induction Machine (DFIM) operating in motor mode for marine propulsion systems. It can be achieved by the additional degree of freedom it provides, firstly, by exploiting the natural structural redundancy, and secondly, by the alytical redundancy introduced by applied control strategies. The first part of this thesis presents the modeling of a propeller architected mainly around the DFIM and its load such as a propeller with three fixed and symmetrical blades. Several control strategies have been introduced to control the system, in fact, linear and nonlinear control laws type associated with various modulators have been validated and applied to the propulsion structure. The objective was to evaluate the influence of these techniques for two major design criteria, namely, losses in power converters, and noise and vibration noise. Naval propulsion as any embedded system has requirements for the quality of service not only in performance but also reliability and availability. Indeed, the systems designed for these types of applications must ensure and guarantee continuity of service in response to the failures in system components. The use of MADA in propulsion systems provides a natural structural and analytical redundancies which ensure system service continuity in the presence of a fault in this structure. Two faults are considered in this study, a power semiconductor fault in the power converter and a speed sensor / position failure. Control strategies proposed, the propeller modeling established and reconfigurations adopted following settings have been validated by simulation and experimentally on the real laboratory or industrial benches developed in the context of this study.

Im Zuge strenger werdender Emissionsrichtlinien und steigender Kraftstoffpreise spielt die Energieeffizienz mobiler Arbeitsmaschinen eine zunehmend wichtigere Rolle. Die Firma Gottwald Port Technology GmbH hat in diesem Zusammenhang einen hybriden Antriebsstrang für einen Hafenmobilkran (HMK) in Zusammenarbeit mit der Technischen Universität Dresden erforscht und umgesetzt. Bei diesem Hybridsystem wird die kinetische und potentielle Energie aus dem elektrischen Hub- und Drehwerk des Krans, welche zuvor im Bremswiderstand in Wärme umgewandelt wurde, durch einen elektrischen Energiespeicher zurückgewonnen. Im Gegensatz dazu ist das hydraulisch betriebene Wippwerk noch nicht rückspeisefähig. Ziel dieser Arbeit ist die Identifikation einer technischen Lösung zur Energierückgewinnung aus der hydraulischen Anlage eines HMK und die Bewertung des erreichbaren Kraftstoffeinsparpotentials. Zunächst wird das bestehende hydraulische System untersucht, um die Anforderungen an das rückspeisefähige Konzept zu ermitteln. Dazu werden Modelle der Kinematik und Kinetik des Wippwerks abgeleitet. Anhand einer Entscheidungsanalyse wird ein hydraulisches Konzept aus einem Katalog verfügbarer Alternativen ausgewählt. Im Anschluss daran wird ein energieflussbasiertes Modell des Konzepts in Matlab/Simulink erstellt und in das bestehende Simulationsmodell integriert. Die Simulationsergebnisse zeigen ein großes Einsparpotential an Dieselkraftstoff durch den Einsatz des rückspeisefähigen Hydrauliksystems. / Due to stricter emission restrictions and rising fuel costs energy efficiency of mobile work machines is getting more important. In cooperation with Dresden University of Technology, Gottwald Port Technology GmbH has developed a mobile harbour crane with a hybrid drive train. This system can recuperate the kinetic and potential energy from the electrical slewing and hoisting gear, which was formerly dissipated to heat. This paper deals with the identification of a technical solution to recuperate energy form the hydraulic luffing gear to determine the potential reduction of fuel consumption. At first, the actual hydraulic system is analyzed to estimate the requirements of the new recuperation system. For that purpose, models of the kinematics and kinetics of the luffing gear are created. With the help of weighted criteria, a hydraulic concept is chosen of several alternatives. Afterwards, an energy flow based model in Simulink/Matlab is created and integrated in the existing simulation model of the crane. The simulation results confirm a considerable reduction of diesel fuel due to the application of hydraulic recuperation system.

Heutzutage gewinnt die Simulation von Gebäuden und Anlagen zunehmend an Bedeutung, um die Betriebsweise der Anlagen zu diagnostizieren bzw. zu bewerten und den Energiebedarf vorherzusagen. Dabei hängt die erzielte Genauigkeit von dem Kompliziertheitsgrad des angewendeten Simulationsprogramms ab. Deshalb ist Modellbildung und -validierung ein sehr wichtiger Bestandteil eines Softwareentwicklungsprozesses, um die Zuverlässigkeit zu sichern. Am Institut für Thermodynamik und Technische Gebäudeausrüstung liegen zahlreiche Simulationsmodelle vor. Im Rahmen dieser vorliegenden Arbeit wurden weitere benötigte Modelle (hygrisches Verhalten der Wände (vereinfachtes Verfahren), Rippenrohrwärmeüberträger, Wärmeregenerator et al.) entwickelt und in das Programm TRNSYS eingefügt sowie die vorhandenen Modelle an ihre Genauigkeit angepasst. Insbesondere sind dies die Modelle für Splitsysteme bei stetiger und nichtstetiger Regelung mit der detaillierten Betrachtung des Anlagenverhaltens sowohl beim Voll- als auch beim Teillastbetrieb. Damit ist es erstmals gelungen, das gesamte Anlagensystem der Splittechnik ausführlich zu beschreiben. Um die analytische Validierung durchführen zu können, wurden die analytischen Modelle für eine Splitanlage bei stetiger und nichtstetiger Regelung unter den vordefinierten Randbedingungen entwickelt. Zur analytischen Validierung finden auch die vorhandenen Simulationsmodelle Anwendung, so dass sich die meisten Komponenten und das Simulationsprogramm TRNSYS verifizieren ließen. Diese Validierung erfolgte im Rahmen des IEA-SHC/HVAC BESTEST TASK 22. Da an diesem TASK verschiedene Forschungsinstitutionen mit jeweils unterschiedlichen Simulationsprogrammen teilnahmen, ergab sich die beste Möglichkeit, vergleichende Tests durchzuführen. Wenn dabei ein Programm signifikante Unterschiede zu den anderen liefert, liegt dies nicht immer an Programmfehlern. Aber kollektive Erfahrungen aus diesem TASK zeigen, dass bei Abweichungen meistens Fehler bzw. fragwürdige Algorithmen gefunden wurden. Nachdem das Simulationsprogramm TRNSYS validiert war, erfolgte die Erstellung eines Konzeptes zur Fehlererkennung und Diagnose der Regelstrategien von RLTA. Das Verfahren erlaubt sowohl die Beseitigung der möglichen Fehler in der Planungsphase beim Entwurf der Regelstrategien als auch den Test der vorhandenen Regelstrategien. Dies erhöht die Zuverlässigkeit und damit die Sicherheit beim Anlagenbetrieb. Schließlich dient das Verfahren als Werkzeug zur Optimierung der Betriebsweise von RLTA. Das Regelverhalten wurde anhand typischer Fälle vorgestellt und diskutiert. Mit Hilfe des Verfahrens zur Fehlererkennung und Diagnose der Betriebsweise von RLTA ließen sich vorhandene Regelstrategien testen und verbessern.

In control technique there is evident highly expressive trend of shifting from efficient central managing systems towards smaller systems which are distributed on technology and which are connected by communication bus. There is no need to link all signals to central management system, operation is then distributed and realized directly in individual parts of technology. That’s why these systems are called distributive managing systems. Distributive managing systems are widely used not only in industrial applications but also in buildings, cars, etc..
