Acoustic sensors have been utilized commercially for more than 60 years. Acoustic sensing technologies have been studied extensively and the information, transmission, reception, transformation, processing, and application of acoustic signals have been developed, with acoustic sensors as the central focus. An acoustic sensor is a device that converts a sound wave signal into an electrical signa…
Thanks to the progress made in materials research and to the introduction of innovative manufacturing technologies, a wide range of sound-absorbing elements are currently available to adjust the acoustic features of an environment. Nowadays, performance is only one of the required specifications, together with environmental compatibility, longevity, and affordable cost. This book collects the m…
This book is intended for all those professionals with interest in developing a basic background in acoustic emission and its use as a non-destructive testing technique. The monitoring of high-power microwave radar tubes is an example of the use of such techniques. This book will also be of interest to those involved in the design, maintenance and procurement of high-power microwave radar tubes…

"In this fascinating collection of essays, an international group of scholars explores the sonic consequences of transcultural contact in the early modern period. They examine how cultural configurations of sound impacted communication, comprehension, and the categorisation of people. Addressing questions of identity, difference, sound, and subjectivity in global early modernity, these authors …

The "Introductory Review" chapter focuses on the terms "acne" and "acneiform," one of which is a multifactorial disease of pilosebaceous unit and the other refers to dermatoses, which res…
Digitale Technologien und Methoden haben in den vergangenen Jahren immer mehr Einfluss auf die geisteswissenschaftliche Forschung gewonnen. Dies gilt nicht minder fur das achtzehnte Jahrhundert: In allen einschlagigen Fachbereichen werden seit Jahren Texte, Bilder und Metadaten digital generiert, verarbeitet, analysiert und prasentiert. Ergebnis ist eine bisher nie dagewesene Konfrontation mit …
Achilles tendon has always attracted a great attention. Its disorders include various problems from pain and swelling with bumps to functional impairment or even ruptures. Debates concerning aetiology and optimal treatment are still going on. A lot of efforts and research have already been put on to find the answers to unsolved problems and this book is an attempt to share (some of) these findi…
This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researcher…
In the face of challenges posed by a shifting digital media landscape, an array of international bodies continue to endorse public service media (PSM) as an essential component of democratisation. Yet how can PSM achieve viability in settings where models of media independence and credibility are unfamiliar or rejected by political leaders? The answer lies in a holistic approach that is neither…
