Book Description
Accurate fluid level measurement in dynamic environments can be assessed using a Support Vector Machine (SVM) approach. SVM is a supervised learning model that analyzes and recognizes patterns. It is a signal classification technique which has far greater accuracy than conventional signal averaging methods. Ultrasonic Fluid Quantity Measurement in Dynamic Vehicular Applications: A Support Vector Machine Approach describes the research and development of a fluid level measurement system for dynamic environments. The measurement system is based on a single ultrasonic sensor. A Support Vector Machines (SVM) based signal characterization and processing system has been developed to compensate for the effects of slosh and temperature variation in fluid level measurement systems used in dynamic environments including automotive applications. It has been demonstrated that a simple ν-SVM model with Radial Basis Function (RBF) Kernel with the inclusion of a Moving Median filter could be used to achieve the high levels of accuracy required for fluid level measurement in dynamic environments. Aimed toward graduate and postgraduate students, researchers, and engineers studying applications of artificial intelligence, readers will learn about a measurement system that is based on a single ultrasonic sensor which can achieve the high levels of accuracy required for fluid level measurement in dynamic environments.

Book Description
This book is a translation of 'Physik und Technik des Ultraschalls', originally published in 1988 by S. Hirzel Verlag, Stuttgart. As in the German edition, it is based on lectures on ultrasound which the author has given over the past fifteen years to students of electrical engineer ing and physics at the Rheinisch-Westfiilische Technische Hochschule Aachen, Germany. Its purpose is to explain and describe the peculiarities of high frequency sound with general acoustics as a foundation. It is these peculiarities which have led to the development of specific methods of sound generation and sound detection on the one hand and are relevant to the way ultrasound propagates in various materials, and which are the origin of a wide range of technical applications on the other. The first part of the book is devoted to the fundamentals of ultrasonics. Since the reader is not expected to have a knowledge of general acoustics, introductory chapters survey the basic ideas and laws of acoustics without systematically deriving the formulae pre sented. Likewise, the third chapter, which deals with the radiation and diffraction of sound, is still fairly general, although it is somewhat more adapted to the specific requirements of ultrasound. In the three subsequent chapters, the generation and detection or measurement of ultrasound is dealt with. The seventh chapter is a digression on the peculiarities of the hypersonic range.

Book Description
A digital twin is a digital representation of a real-world counterpart, which can receive and provide data to create value within a use case. Digital twins create value for users by enabling new and enhanced smart services. However, ambiguous definitions and terminology coupled with a lack of shared conceptual reference frameworks complicate cross-functional discussions and hinder the widespread implementation of digital twins. This thesis proposes a new definition and presents two conceptual reference frameworks to systematically depict value creation with digital twins. A design science research approach with mixed methods was used to iteratively design and evaluate these artifacts while ensuring scientific rigor, practical relevance, and usefulness. The applied methods within the five research phases include systematic literature research, interviews, workshops with academic experts, qualitative and quantitative questionnaires, workshops with practice experts, and an in-depth case study in smart waste management. The major findings of this research are (i) the proposal of a new definition of digital twins that reflects a practical understanding by focusing on value creation; (ii) a scientific conceptual reference framework focusing on completeness by distinguishing 81 elements involved in value creation with digital twins; (iii) a second, more application-oriented conceptual reference framework focusing on the interrelations of the elements essential for the value creation in practice; and (iv) an instantiation of the application-oriented framework for the use case of the in-depth case study. All artifacts are consistent in content and include the following main dimensions, which are to be considered when creating value with digital twins: data resources, internal value creation, and external value creation. These artifacts contribute to a common understanding of value creation with digital twins in research and practice. Furthermore, they enable researchers and practitioners to structure their digital twin activities and communicate them to internal and external stakeholders.
