The key science and technology challenges which will facilitate the transition from a "make do and mend" philosophy inevitably restricting the degree of intelligence which can be engineered and the "designer materials systems" philosophy which is the ultimate goal are considered. The longer term vision will need to accord much more closely with nature's design paradigms, with control at the molecular, nano, micro and macro level of synthesis and assembly, of active self repair materials systems in function shapes.
This classic and authoritative student textbook contains information that is not over simplified and can be used to solve the real world problems encountered by noise and vibration consultants as well as the more straightforward ones handled by engineers and occupational hygienists in industry. The book covers the fundamentals of acoustics, theoretical concepts and practical application of current noise control technology. It aims to be as comprehensive as possible while still covering important concepts in sufficient detail to engender a deep understanding of the foundations upon which noise control technology is built. Topics which are extensively developed or overhauled from the fourth edition include sound propagation outdoors, amplitude modulation, hearing protection, frequency analysis, muffling devices (including 4-pole analysis and self noise), sound transmission through partitions, finite element analysis, statistical energy analysis and transportation noise. For those who are already well versed in the art and science of noise control, the book will provide an extremely useful reference. A wide range of example problems that are linked to noise control practice are available on www.causalsystems.com for free download.
Loudness is the primary psychological correlate of intensity. When the intensity of a sound increases, loudness increases. However, there exists no simple one-to-one correspondence between loudness and intensity; loudness can be changed by modifying the frequency or the duration of the sound, or by adding background sounds. Loudness also changes with the listener’s cognitive state. Loudness provides a basic reference for graduate students, consultants, clinicians, and researchers with a focus on recent discoveries. The book begins with an overview of the conceptual thinking related to the study of loudness, addresses issues related to its measurement, and later discusses the physiological effects of loud sounds, reaction times and electrophysiological measures that correlate with loudness. Loudness in the laboratory, loudness of steady-state sounds and the loudness of time-varying sounds are also covered, as are hearing loss and models.
Smart mobile systems such as microsystems, smart textiles, smart implants, sensor-controlled medical devices and innovative sensor techniques have become important enablers for telemedicine and next-generation health services, with social media and gamification adding further to personalized health (pHealth) as an eco-system. This book presents the proceedings of pHealth 2017, the 14th in a series of international conferences for personalized health held in Eindhoven, the Netherlands, in May 2017. The conference series, which began in 2003 as a dissemination activity in the framework of a European project on wearable micro and nano technologies for personalized health, presents advances in wearable or implantable micro-, nano- and bio-technologies for healthcare and wellness, and brings together expertise from medical, technological, political, administrative, and social domains, and even from philosophy and linguistics. The book contains keynotes and invited papers, as well as 16 oral presentations and 8 poster presentations. Encompassing diverse fields such as medical services, public health, prevention, social and elderly care, wellness and personal fitness, the book will be of interest to practitioners from various medical and health disciplines, as well as developers and administrators, provider institutions, and patient and citizens representatives.
