Compression: From Cochlea to Cochlear Implants (Springer Handbook of Auditory Research)

Book Description

The mechanical response of the basilar membrane in the cochlea plays a fundamental role in human hearing. This volume discusses the main aspects of cochlear compression, including anatomy and physiology; the perceptual consequences of compression in normal hearing; the effects of hearing loss on compression; and its function in hearing aids and cochlear implants. The role of compression has increasing practical significance as it is incorporated into hearing aids and cochlear implants to compensate for inadequate compression in people with cochlear hearing loss.

Book Description

Volume 42 of the Solubility Data Series contains evaluated data for the solubility of hydrogen fluoride, hydrogen chloride, hydrogen bromide and hydrogen iodide in non-aqueous solvents. Information on about four hundred systems is included. Hydrogen halides take part, either as reactants or products, in many reactions of organic compounds. Evaluated solubility data for these gases are required for the prediction of the course and mechanism of such reactions. The volume will therefore be of especial interest to organic chemists and to chemical engineers concerned with syntheses involving halogen compounds in non-aqueous media.

Book Description

This book gives a self-contained and up-to-date account of mathematical results in the linear theory of water waves. The study of waves has many applications, including the prediction of behavior of floating bodies (ships, submarines, tension-leg platforms etc.), the calculation of wave-making resistance in naval architecture, and the description of wave patterns over bottom topography in geophysical hydrodynamics. The first section deals with time-harmonic waves. Three linear boundary value problems serve as the approximate mathematical models for these types of water waves. The next section uses a plethora of mathematical techniques in the investigation of these three problems. The techniques used in the book include integral equations based on Green's functions, various inequalities between the kinetic and potential energy and integral identities which are indispensable for proving the uniqueness theorems. The so-called inverse procedure is applied to constructing examples of non-uniqueness, usually referred to as 'trapped nodes.'

Recovery of Unknown Constraint Length and Encoder Polynomials for Rate 1/2 Linear Convolutional Encoders

Manufacturer: Storming Media
ProductGroup: Book
Binding: Spiral-bound
ASIN: 1423539346

Product Description

This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A539573. The abstract provided by the Pentagon follows: It is sometimes useful to recover convolutionally encoded data without knowing the encoder parameters. The necessary first step is to recover these parameters so that a suitable decoder can be selected. In this study an attempt is made to recover the unknown constraint length K and the convolutional code polynomials for a feedback-free rate 1/2 encoder from a received data stream. It will be shown that the output of such an encoder uniquely characterizes it and permits unambiguous identification of both K and the polynomials if the input data stream is sufficiently exciting and if the received encoded stream is both abundant and is free of transmission error. The encoder output can be collected and collated in a manner that permits synthesis of an impulse response. Even though such an impulse input has not occurred, from the synthesized sequence one may derive the encoder parameters. The application of this synthetic impulse response algorithm with noisy data is then explored, and directions for further research are identified.

Book Description

The way in which wind blows over water and causes waves to be generated is still a very active area of research for applied mathematicians, as well as for oceanographers and engineers. The basic mechanisms are still a matter of controversy, although the use of modern techniques of asymptotic and non-linear analysis and large-scale computation, as well as experimental structures, have begun to demonstrate which are the dominant mechanisms in different types of wind-wave regimes. These studies result in practical methods of forecasting waves and their effects on sediment, pollution, offshore structures, etc., and even lead to methods of controlling them. These are the themes covered by the papers in this book, written by many of the leading authorities in the field.

Description:
Electroanalytical techniques have been used to determine methylmercury at low levels in environmental matrices. The electrochemical behaviour of methylmercury at carbon microelectrodes in a hydrochloric acid medium using cyclic, square wave and fast-scan linear-sweep voltammetric techniques has been investigated. The analytical utility of the methylmercury reoxidation peak has been explored, but the recorded peak currents were found to be poorly reproducible. This is ascribed to two factors: the adsorption of insoluble chloromercury compounds on the electrode surface, which appears to be an important contribution to hinder the voltammetric signal of methylmercury; and the competition between the reoxidation of the methylmercury radical and its dimerization reaction, which limits the reproducibility of the methylmercury peak. These problems were successfully overcome by adopting the appropriate experimental conditions. Fast-scan rates were employed and an efficient electrochemical regeneration procedure of the electrode surface was achieved, under potentiostatic conditions in a mercury-free solution containing potassium thiocyanate-a strong complexing agent. The influence of chloride ion concentration was analysed. Interference by metals, such as lead and cadmium, was considered. Calibration plots were obtained in the micromolar and submicromolar concentration ranges, allowing the electrochemical determination of methylmercury in trace amounts. An estuarine water sample was analysed using the new method with a glassy carbon microelectrode.

Book Description

The hero of Darcy O'Brien's A Way of Life, Like Any Other is a child of Hollywood, and once his life was a glittery dream. His father starred in Westerns. His mother was a goddess of the silver screen. The family enjoyed the high life on their estate, Casa Fiesta. But his parents' careers have crashed since then, and their marriage has broken up too.

Lovesick and sex-crazed, the mother sets out on an intercontinental quest for the right—or wrong—man, while her mild-mannered but manipulative former husband clings to his memories in California. And their teenage son? How he struggles both to keep faith with his family and to get by himself, and what in the end he must do to break free, makes for a classic coming-of-age story—a novel that combines keen insight and devastating wit to hilarious and heartbreaking effect.

Livestyles of the formerly rich and famous.......2006-09-12

In his introduction to this reissue of a novel first published in 1977, Seamus Heaney dwells on Darcy O'Brien's Irishness (comparing him to Joyce and Flann O'Brien) and ponders how one might attempt to describe the book: "Autobiographical novel, fictionalized memoir: whether we regard the book as 'cri de coeur' or comic turn..."

O'Brien's Irish heritage seems beside the point (must every Irish American writer be placed against Joyce and Flann O'Brien?), but this is, indeed, a work that skirts the line between fact and fiction. Heaney's literary acumen aside, this is also a very American book--more specifically a highbrow model of that lowest of middlebrow fiction, the Hollywood novel. More germanely to the author, it is a raw, impassioned, and surprisingly tender ode to his parents--a pair of has-been, real-life film stars down on their luck and at odds with each other. Finding humor (both lighthearted and morbid) amid relative misery, "A Way of Life" is far more a precursor to the confessional works by the likes of David Sedaris, Augusten Burroughs, and Jeannette Walls than a successor to early-twentieth-century Irish fiction.

Hollywood has never been shy about laughing at itself; readers will recognize many of the central-casting players depicted here, along with the shallow pretensions of the jet set. But O'Brien's succinct, disarmingly blunt prose places his book a cut above the norm--even his caricatures are fully drawn with the briefest of scenes: the ego-driven producer with an out-of-control gambling addiction, his permissive wife whose major concern is that her own daily horse-racing allowance might suffer as a result, their unrestrained and oversexed adolescent son, a pompous salesman of trendy foodstuffs (in the 1950s, those would include, hilariously, avocadoes), a flighty car dealer who peddles John Birch Society tracts along with his automobiles. Adding to the book's authenticity are cameos by real people, including John Ford, who in life directed O'Brien's father in several movies and who in fiction is portrayed as a gentlemanly mentor who graciously meets with his hapless former leading man.

But the real "stars" of the novel are O'Brien's parents. The unnamed narrator's charmed, pampered early life is ripped apart when his parents split and their finances suffer. His mother flits from one abusive or inappropriate replacement to another; his father refuses to accept their estrangement: "Your Mother and I are still married in the eyes of the Church." Their son first lives with his mother, then with his father, and finds that they both have become uproariously and painfully impossible. Eventually, he moves into a friend's expansive and expensive home and discovers that all unhappy families are unhappy in their own way, but it's to O'Brien's credit that he is able to make this journey both comical and heartrending at the same time.

Amazing Feat of Compression and Eloquence.......2003-01-10

The writing here is so filled with generosity, compassion, and dark humor -- it's a most charming view of life. A coming-of-age novel about a boy who grows up in post-WW II Hollywood, shuffling between unforgettable, screwed-up parents. There's not a dead sentence here. It's short, but O'Brien captures it all. Completely re-readable. Keep it by your bedside to inspire and forgive your own life when you feel like it's trying to beat you down.

A Fantastic Novel.......2002-07-29

This is a MUST. Indeed it is Caulden Houlfield in Hollywood. If you like Catcher in the Rye, most likely you will love this book. It really is a great story with some great humor.

A Way of Life.......2001-12-11

Darcy O'Brien combines the surreal humor of Flann O'Brien and the limpid prose of the young James Joyce and somehow writes a coming of age book which transcends both mentors in some ways. Lean, cool, dry, witty, but in the end, mysteriously poignant. Anthony Powell always argued that seen at close range all human beings, driven as they are at different speeds by the same furies, are equally extraordinary. O'Brien proves Powell's point, in prose reminscent of that master's early comic novels.

A fine portrait of the artist as a young man.......2001-08-28

Darcey O'Brien's fine Bildungsroman is a very funny and lethal depiction of a golden Hollywood childhood which begins to tarnish as his parents' careers do. The narrator's parents--a histrionic former screen beauty obsessed with sex and a former Western star of amiable disposition but sometimes hidden motives--unconsciously (and even sometimes consciously) wreak all kinds of havoic in their son's life, but as he gets older the son begins to fight back in covert ways. This was exactly the kind of book that the NYRB series was created to revive: a funny and poignant novel of sterling quality that somehow slipped through the cracks of readers' attention years ago and deserves a new chance.
