This book provides an analysis of acoustic features of polysemous strings and an implementation of a speech disambiguation program based on the phonetic information. Throughout the book, the term 'polysemous string' refers to idioms with plausible literal interpretations, restrictive and non-restrictive relative clauses, and the same expressions used as quotations and appearing in a non-quotational context. The author explains how, typically, context is sufficient to determine the intended meaning. But there is enough evidence in psycholinguistic and phonetic literature to suspect that these superficially identical strings exhibit different acoustic features. In the experiment presented in the book, the participants were asked to read short excerpts containing corresponding elements of polysemous strings placed in the same intonational position. The acoustic analyses of ditropic pairs and subsequent statistical tests revealed that there is almost no difference in the duration, pitch, or intensity in literal and figurative interpretations. However, the analysis of relative clauses and quotations demonstrated that speakers are more likely to use acoustic cues to differentiate between the two possible readings. The book argues that the acoustic analysis of polysemous phrases could be successfully implemented in designing automatic speech recognition systems in order to improve their performance in disambiguating polysemous phrases.Analyzes acoustic features of polysemous strings and an implementation of a speech disambiguation programIncludes evidence that superficially identical strings exhibit different acoustic featuresArgues that acoustic analysis of polysemous phrases can be successfully implemented in automatic speech recognition

First, the Prime Power subsystem comprises the storage of energy to be radiated by the HPM Source and Antenna. The Power Conditioning subsystem takes the stored energy and makes it usable to the HPM Source, both by voltage conversion and pulse shaping. The HPM Source takes the transformed energy and creates the high-power microwave by either drastically oscillating or amplifying the voltage. Finally, the Antenna radiates the high-power microwaves at the desired frequency and gain to produce an effect in the target. Of the 4 HPM subsystems, this book specifically outlines the design and implementation of a Power Conditioning HPM subsystem developed for MTSDO at Radiance Technologies

This book explains how depth measurements from the Time-of-Flight (ToF) range imaging cameras are influenced by the electronic timing-jitter. The author presents jitter extraction and measurement techniques for any type of ToF range imaging cameras. The author mainly focuses on ToF cameras that are based on the amplitude modulated continuous wave (AMCW) lidar techniques that measure the phase difference between the emitted and reflected light signals. The book discusses timing-jitter in the emitted light signal, which is sensible since the light signal of the camera is relatively straightforward to access. The specific types of jitter that present on the light source signal are investigated throughout the book. The book is structured across three main sections: a brief literature review, jitter measurement, and jitter influence in AMCW ToF range imaging.

This contributed volume tells the story of the establishment of a cybersecurity awareness framework for organizations, and how it was piloted in two public sector municipal contexts. It presents a clear picture of cybersecurity issues in municipalities and proposes a socio-technical solution for creating cybersecurity awareness, how to build the solution and what the impact is on the municipal contexts. The 9 chapters for this book also provide information regarding the design, the deployment and the evaluation of the technology.This book builds on the success of the European Horizon 2020 research and innovation project CS-AWARE. The research proposes the first cybersecurity situational awareness solution for local public administrations based on an analysis of the context, provides automatic incident detection and visualization, and enables information exchange with relevant national and EU level authorities involved in legislation and network security.Cybersecurity is one of the most challenging security problems for commercial companies, NGOs, governmental institutions as well as individuals. Reaching beyond the technology focused boundaries of classical information technology (IT) security, cybersecurity includes organizational and behavioral aspects of IT systems and that needs to comply to legal and regulatory framework for cybersecurity. While large corporations might have the resources to follow those developments and bring their IT infrastructure and services in line with the requirements, the burden for smaller organizations like local public administrations will be substantial and the required resources might not be available. New and innovative solutions that would help local public administration to ease the burden of being in line with cybersecurity requirements are needed.This book targets researchers working in cybersecurity, computer scientists, social scientists and advanced level students studying computer science and other related disciplines. Cybersecurity professionals as well as professionals working in local government contexts, including policy makers, communication experts and system administrators will also benefit from this book.

This book presents experimental studies on emergent transport and magneto-optical properties in three-dimensional topological insulators with two-dimensional Dirac fermions on their surfaces. Designing magnetic heterostructures utilizing a cutting-edge growth technique (molecular beam epitaxy) stabilizes and manifests new quantization phenomena, as confirmed by low-temperature electrical transport and time-domain terahertz magneto-optical measurements. Starting with a review of the theoretical background and recent experimental advances in topological insulators in terms of a novel magneto-electric coupling, the author subsequently explores their magnetic quantum properties and reveals topological phase transitions between quantum anomalous Hall insulator and trivial insulator phases; a new topological phase (the axion insulator); and a half-integer quantum Hall state associated with the quantum parity anomaly. Furthermore, the author shows how these quantum phases can be significantly stabilized via magnetic modulation doping and proximity coupling with a normal ferromagnetic insulator. These findings provide a basis for future technologies such as ultra-low energy consumption electronic devices and fault-tolerant topological quantum computers.

Diese Meisterarbeit zum Thema "Topographischer Einfluss bei der Analyse der Erkennung von Veränderungen unter Verwendung von Satellitendaten" umfasste verschiedene Arten von Korrekturen wie geometrische, atmosphärische, radiometrische und topographische Korrekturen, um die unerwünschten Auswirkungen von multispektralen Satellitenbildern zu beseitigen. In jüngster Zeit ist die Nutzung von Multispektraldaten in verschiedenen Anwendungen wie der Überwachung der Schadensbeurteilung, der Überwachung der Landnutzung und -bedeckung (LULC), von Schneelawinen oder Sturzfluten sowie der Analyse von Veränderungen exponentiell gestiegen. Daher ist es notwendig, die vorbereitenden Schritte durchzuführen, bevor man zur weiteren Analyse übergeht. Dieses Buch ist in erster Linie als Lehrbuch für Forscher auf dem Gebiet der Satellitenbildverarbeitung, Fernerkundung, Analyse von Veränderungen und topografischen Korrekturen gedacht. Es wird erwartet, dass solche Korrekturen in den vorbereitenden Schritten eine effektive Rolle bei der operativen Überwachung oder Kartierung von LULC spielen könnten. Die verschiedenen topografischen Korrekturmethoden werden verglichen und dann wird eine geeignete topografische Korrekturmethode für die Schneebedeckung im Himalaya zur Analyse der Veränderungserkennung angewendet. Darüber hinaus wurde dieses Verfahren auf die Daten von zwei Sensorsatelliten (AWiFS und MODIS) angewendet.
