Abstract

Large linguistic corpora are becoming increasingly important for linguistic work. For several years now, research endeavors have been dedicated to the construction of large corpora, the theory of data and corpora, as well as the development of methods in corpus analysis. The current volume focuses on theoretical and methodological questions about the compilation and use of large corpora and deals with these questions from the perspective of various linguistic subdisciplines, such as grammar, lexicon/lexicography, pragmatics/sociolinguistics and computer linguistics/informatics.

Abstract

Sowohl bei der Fertigung industrieller Zwischenprodukte als auch bei der Produktion von Konsumgütern treten vielerlei glänzende bzw. spiegelnde Oberflächen auf. Während bei technischen spiegelnden Oberflächen, wie z.B. Press- bzw. Gusswerkzeugen oder optischen Bauelementen, die Funktionalität des Werkstücks durch Oberflächendefekte gefährdet ist, stehen bei Produkten für den Endkunden, wie z.B. Armaturen, Musikinstrumenten oder lackierten Autokarosserien, ästhetische Aspekte im Vordergrund. Gerade im Bereich der Automobilindustrie sind die Qualitätsansprüche der Endkunden in den letzten Jahren enorm gestiegen, so dass marktübliche Verfahren zur Qualitätssicherung allmählich an ihre Grenzen stoßen.Ein Messverfahren, das den gestiegenen Anforderungen an Genauigkeit und Geschwindigkeit weitgehend gerecht wird, ist die Deflektometrie. Sie ist dem menschlichen Verhalten beim Prüfen spiegelnder Oberflächen nachempfunden. Aufbauend auf dem deflektometrischen Messprinzip wurden im Rahmen dieser Arbeit Algorithmen entwickelt, welche die Planung eines deflektometrischen Messaufbaus automatisieren. Für eine präzise Messung geringer Krümmungsänderungen wurden darüber hinaus Methoden vorgestellt, welche die Phase der optischen Abbildungsfunktion analysieren. Weiterhin wurden Verfahren entwickelt, welche die punktweise Fokusänderung messen. Diese zeichnen sich durch eine hohe Geschwindigkeit aus und ermöglichen eine empfindliche Erkennung von Defekten mit geringer lateraler Ausdehnung (Blasen, Einschlüsse) in Echtzeit. Die Leistungsfähigkeit der entwickelten Verfahren wurde dabei nicht nur in Simulationen demonstriert, sondern auch an Hand von realen, industrierelevanten Oberflächen, wie Karosserieteilen, Linsen und Spiegeln.

Abstract

Structural health monitoring (SHM) has attracted more attention during the last few decades in many engineering fields with the main aim of avoiding structural disastrous events. This aim is achieved by using advanced sensing techniques and further data processing. SHM has experienced booming advancements during recent years due to the developments in sensing techniques. The reliable operation of current, sophisticated, man-made structures drives the development of incipient reliable damage diagnosis and assessment. This book aims to illustrate the background and applications of SHM from both sensing and processing approaches. Its main objective is to summarize the advantages and disadvantages of SHM methodologies and their applications, which may provide a new perspective in understanding SHM for readers from diverse engineering fields.

Abstract

Sensor data fusion is the process of combining error-prone, heterogeneous, incomplete, and ambiguous data to gather a higher level of situational awareness. In principle, all living creatures are fusing information from their complementary senses to coordinate their actions and to detect and localize danger. In sensor data fusion, this process is transferred to electronic systems, which rely on some ""awareness"" of what is happening in certain areas of interest. By means of probability theory and statistics, it is possible to model the relationship between the state space and the sensor data. The number of ingredients of the resulting Kalman filter is limited, but its applications are not.

Abstract

The use of the wavelet transform to analyze the behaviour of the complex systems from various fields started to be widely recognized and applied successfully during the last few decades. In this book some advances in wavelet theory and their applications in engineering, physics and technology are presented. The applications were carefully selected and grouped in five main sections - Signal Processing, Electrical Systems, Fault Diagnosis and Monitoring, Image Processing and Applications in Engineering. One of the key features of this book is that the wavelet concepts have been described from a point of view that is familiar to researchers from various branches of science and engineering. The content of the book is accessible to a large number of readers.
