This is a unique book on the mathematics of signals written for hearing-science researchers. Designed to follow an introductory text on psychoacoustic, Signals, Sound, and Sensation takes the reader through the mathematics of signal processing from its beginnings in the Fourier transform to advanced topics in modulation, dispersion relations, minimum phase systems, sampled data, and nonlinear distortion. While the book is organized like an introductory engineering text on signals, the examples and exercises come from research on the perception of sound. A unique feature of the book is the consistent application of the Fourier transform, which unifies topics as diverse as cochlear filtering and digital recording. More than 250 exercises are included. Many of them are devoted to practical research in perception, while others explore surprising auditory illusions generated by special signals. A working knowledge of elementary calculus is the only prerequisite. Signals, Sound, and Sensation will help readers acquire the quantitative skills they need to solve signal problems that arise in their everyday work. Periodic signals, aperiodic signals, and noise - along with their linear and nonlinear transformations - are covered in detail. More advanced mathematical topics are treated in the appendices. In no other book are signal mathematics and psychoacoustics so neatly intertwined. Researchers and advanced students in the psychology of auditory perception will find this book indispensable.

Das Buch beinhaltet in praxisgerechter Form die Darstellung der aktuellen und gAngigen Methoden der phlebologischen Diagnostik und Therapie inklusive der bildgebenden Verfahren i. S. der immer wichtiger werdenden Duplexsonographie und Phlebographie. Es wird umfassend auf die konservative Therapie eingegangen, insbesondere die Kompressionstherapie, aber auch auf die Pharmakotherapie bei der chronisch-venAsen Insuffizienz. Aktuelle Aspekte der Thromboseprophylaxe und -therapie werden berA1/4cksichtigt. Das Buch enthAlt zahlreiche Tabellen und Abbildungen in Form von Zeichnungen und Fotodokumentationen. Der besondere Nutzen besteht in der AktualitAt der BeitrAge und der MAglichkeit, in vergleichsweise kurzer Zeit einen Aoeberblick A1/4ber phlebologische Fragestellungen zu bekommen.

Principles of Musical Acoustics focuses on the basic principles in the science and technology of music. Musical examples and specific musical instruments demonstrate the principles. The book begins with a study of vibrations and waves, in that order. These topics constitute the basic physical properties of sound, one of two pillars supporting the science of musical acoustics. The second pillar is the human element, the physiological and psychological aspects of acoustical science. The perceptual topics include loudness, pitch, tone color, and localization of sound. With these two pillars in place, it is possible to go in a variety of directions. The book treats in turn, the topics of room acoustics, audio both analog and digital, broadcasting, and speech. It ends with chapters on the traditional musical instruments, organized by family. The mathematical level of this book assumes that the reader is familiar with elementary algebra. Trigonometric functions, logarithms and powers also appear in the book, but computational techniques are included as these concepts are introduced, and there is further technical help in appendices.

Entzugserscheinungen nach jahrelangem Drogen-und Alkoholabusus entwickeln sich nach sehr ahnlichen pathophysiologischen Mustern und sind in ihrer Entste- hung oft schwierig zu deuten. Sie auBern sich vorwiegend in vegetativen Reaktionen, die meist den initialen Wirkungen entgegengesetzt sind. Ihre Intensitat ist je nach Substanz, Dosis, Darreichungsart und Dauer der Anwendung unterschiedlich. Toleranzbildung und die Entwicklung einer Abhangigkeit nach chronischem AlkoholmiBbrauch erschweren die Betreuung von Patienten vor allem in der postoperativen Phase. Angesichts der steigenden Anzahl alkoholabhangiger Patienten in unserer Gesellschaft kommt daher der Prophylaxe und Therapie des Alkoholentzugssyndroms bei gegebener Operationsindikation wachsende Bedeu- tung zu. Das standig zunehmende Interesse an praventiven MaBnahmen fiihrte im Februar 1990 Experten in Hannover zu einem Symposium zusammen, das der Diskussion gegenwartiger und neuer Aspekte der Delirtherapie und -prophylaxe gewidmet war. Die in dem vorliegenden Kompendium zusammengefaBten Beitrage geben einen Einblick in die Klinik und Pathophysiologie des Alkoholentzugsdelirs. Dartiber hinaus werden wichtige Fragen der Pharmakologie und Pharmakokinetik behan- delt und praktisch-therapeutische Konsequenzen aufgezeigt. Eine orale Alkoholmedikation ist wohl bei kleineren Eingriffen in speziellen Fallen erfolgreich, dartiber hinaus gilt es jedoch, dem Therapeuten ein angemes- senes medikamentoses Konzept zur Delirprophylaxe und -therapie an die Hand zu geben. 1m Mittelpunkt des Interesses steht derzeit die Beeinflussung der Entzugssym- ptome bei Alkoholabhangigen durch Gabe zentral wirkender urStimulanzien.

Dieser Buchtitel ist Teil des Digitalisierungsprojekts Springer Book Archives mit Publikationen, die seit den Anfangen des Verlags von 1842 erschienen sind. Der Verlag stellt mit diesem Archiv Quellen fur die historische wie auch die disziplingeschichtliche Forschung zur Verfugung, die jeweils im historischen Kontext betrachtet werden mussen. Dieser Titel erschien in der Zeit vor 1945 und wird daher in seiner zeittypischen politisch-ideologischen Ausrichtung vom Verlag nicht beworben.

This intriguing book enriches our understanding of the women's movement in the United States by showing how feminists captured a place for their goals on the agendas of four male-dominated liberal organizations in the 1960s and 1970s: the American Civil Liberties Union, the National Council of Churches, the Ford Foundation, and the International Union of Electrical Workers. Susan M. Hartmann examines the efforts of women and men who had few ties to the independent women's movement-and thus have been neglected in studies of second-wave feminism-but who nonetheless contributed substantially to the spread of feminist ideas and practices into the mainstream of American society. She identifies key resources that these establishment groups furnished the independent women's movement-money, legitimacy, and access to the critical arenas of public opinion and government. Revising the common view that the second wave of feminism was a white middle-class phenomenon, Hartmann discovers significant numbers of women of color and working-class women who pushed feminist agendas. In demonstrating how feminist change took place within establishment organizations, the book highlights the processes and the benefits that attended the incorporation of feminism into the frames of economic and racial justice, individual rights, and Christian values. It thus illuminates both the reach and the staying power of second-wave feminism.
