Sound power describes the emission of sound from sound sources. Despite today's state-of-the art measurement techniques, the current sound power determination methods are restricted due to various limitations. To overcome these limitations, a new sound power determination method is proposed, aiming at the establishment of traceability in airborne sound. This will enable the characterization of …
Orbital debris is becoming an increasing problem for space flight missions. New satellite launches, explosions, collisions and other events cause a steady rise in the number of objects orbiting the Earth. It is therefore important to determine the future development of the object population, as well as the effectiveness of debris mitigation measures, in long-term simulations. Orbital propagatio…
While binaural technology applications gained in popularity in recent years, the majority of applications still use non-individual Head-Related Transfer Functions (HRTFs) from artificial heads. However, certain applications, for example research of spatial hearing or hearing attention, require an physically exact and realistic binaural signal. The limiting factor that prohibits the widespread u…
This volume assembles contributions from different academic perspectives (religious and Islamic studies, literary and theatre studies, theology, sociology and history) on modern manifestations of martyrdom in the diverse Middle Eastern religious traditions, including Islam, Christianity, Judaism and the Baha'i-faith. The latter is considered in more detail since it is often not included in comp…
The present 9th volume of the series Acarorum Catalogus contains lists of mites of 13 families, 225 genera and 1268 species of the superfamilies Schizoglyphoidea, Histiostomatoidea, Canestrinioidea and Hemisarcoptoidea. Most of these mites live on insects or other animals (as parasites, phoretic or commensals), some inhabit rotten plant material, dung or fungi. Mites of the families Chetochelac…
Autism spectrum conditions (ASC) are neurodevelopmental conditions, characterized by impairments in social interaction, communication (i.e., verbal and non-verbal language), and by restricted interests and repetitive behaviour. The application of robots as a therapy tool has, however, shown promising results, namely because of the robot’s ability to improve social engagement by eliciting appr…
This book explores the role of Catholic peacebuilding in addressing the global mining industry. Mining is intimately linked to issues of conflict, human rights, sustainable development, governance, and environmental justice. As an institution of significant scope and scale with a large network of actors at all levels and substantial theoretical and ethical resources, the Catholic Church is well…
The world has changed dramatically. We no longer live in a world relatively empty of humans and their artifacts. We now live in the “Anthropocene,” era in a full world where humans are dramatically altering our ecological life-support system. Our traditional economic concepts and models were developed in an empty world. If we are to create sustainable prosperity, if we seek “improved huma…
A world-famous singer and actor, a trained lawyer, an early star of American professional football and a polyglot who spoke over a dozen languages. These could be the crowning achievements of a life well-lived, yet for Paul Robeson the higher calling of social justice led him to abandon both the NFL and Hollywood and become one of the most important political activists of his generation— batt…
Declining access to fresh water is one of the twenty-first century’s most pressing environmental and human rights challenges, yet the struggle for water is not a new cause. The 8,800-kilometer border dividing Canada and the United States contains more than 20 percent of the world’s total freshwater resources, and Border Flows traces the century-long effort by Canada and the United States to…
