Very Truly Yours, Nikola Tesla
by Nikola TeslaNikola Tesla was a man of letters. He wrote many letters to the editors of the magazines and newspapers of his day. These letters give a fascinating glimpse into the mind of an eccentric genius. Collected here for the first time are more than forty of Nikola Tesla's letters. The subject matter ranges widely, as Tesla was interested in almost everything. In these letters he responds to Marconi and Edison, gives his thoughts on the wars of his day, corrects inconsistencies in news reports, and much much more. Nikola Tesla has been called the most important man of the 20th Century. Without Tesla's ground-breaking work we'd all be sitting in the dark without even a radio to listen to.
Verzahnungsgeräusche
by Thomas GrünerDieses Fachbuch befasst sich mit der Mess- und Analysetechnik von Verzahnungsgeräuschen, die als „Industriekultur“ eher ein Randthema in der klassischen Lehr- und Fachliteratur darstellt und sich nur in Teilen z. B. in Werken zur Getriebetechnik und zur Zustandsüberwachung von Maschinen (Health-Monitoring) findet. Das Werk widmet sich u. a. Übertragungsfunktionen, der Ordnung und Ordnungsanalyse sowie Ordnungsmustern von Planetentrieben. Drehfehler, Modulation, die Parametererregung und das Windowing werden ebenso behandelt. In dem Buch finden sich keine Differentialgleichungen, obwohl sie die Modelle für z. B. „Resonanz“ oder „Übertragungsfunktion“ liefern würden. Diese Funktionen werden stattdessen aus Messungen geschätzt, um einen praxisnahen Einstieg in das Thema zu ermöglichen.
Vessel Based Imaging Techniques: Diagnosis, Treatment, and Prevention
by Chun Yuan Thomas S. Hatsukami Mahmud Mossa-BashaThis book provides comprehensive information on new and existing vessel imaging techniques, with the intention of improving diagnosis, treatment, and prevention of vascular and related diseases. In recent years, vessel wall imaging has expanded greatly into other beds (such as the intracranial and peripheral arteries) and many of the techniques available for evaluation and diagnosis have only previously been published in research papers. This book bridges that gap for clinicians, applying cutting edge research to their everyday practice. The first six sections of the book are centered around individual vessel beds. These chapters will teach clinicians the multi-modality imaging techniques available to image these vessels and related pathology with a focus on new imaging tools and techniques. The final two sections of the book will offer a more comprehensive technical background aimed at imaging scientists for the imaging techniques used and the relationship of blood flow and modeling to disease monitoring and prevention. This is an ideal guide for radiologists and imaging scientists looking to learn the latest techniques in vessel imaging.
The Vestigial Heart: A Novel of the Robot Age
by Carme TorrasA thirteen-year-old girl wakes up in a future where human emotions are extinct and people rely on personal-assistant robots to navigate daily life. Imagine a future in which many human emotions are extinct, and “emotional masseuses” try to help people recover those lost sensations. Individuals rely on personal-assistant robots to navigate daily life. Students are taught not to think but to employ search programs. Companies protect their intellectual property by erasing the memory of their employees. And then imagine what it would feel like to be a sweet, smart thirteen-year-old girl from the twenty-first century who wakes from a cryogenically induced sleep into this strange world. This is the compelling story told by Carme Torras in this prize-winning science fiction novel. We meet Celia, brought back to life when a cure is found for her formerly terminal disease, and Lu, Celia's adoptive mother, protective but mystified by her new daughter. There is Leo, a bioengineer, who is developing a “creativity prosthesis” to augment humans' atrophied capacities, and the eccentric robotics mogul Dr. Craft. And there is Silvana, an emotional masseuse who reads old books to research the power of emotion. Silvana sees Celia as a living, breathing example of the emotions and feelings that are now out of reach for most people. Torras, a prominent roboticist, weaves provocative ethical issues into her story. What kind of robots do we want when robot companions become as common as personal computers are now? Is it the responsibility of researchers to design robots that make the human mind evolve in a certain way? An appendix provides readers with a list of ethics questions raised by the book.
Veterans and Agent Orange: Update 2014
by National Academies of Sciences Engineering MedicineFrom 1962 to 1971, the US military sprayed herbicides over Vietnam to strip the thick jungle canopy that could conceal opposition forces, to destroy crops that those forces might depend on, and to clear tall grasses and bushes from the perimeters of US base camps and outlying fire-support bases. Mixtures of 2,4-dichlorophenoxyacetic acid (2,4-D), 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), picloram, and cacodylic acid made up the bulk of the herbicides sprayed. The main chemical mixture sprayed was Agent Orange, a 50:50 mixture of 2,4-D and 2,4,5-T. At the time of the spraying, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), the most toxic form of dioxin, was an unintended contaminant generated during the production of 2,4,5-T and so was present in Agent Orange and some other formulations sprayed in Vietnam. Because of complaints from returning Vietnam veterans about their own health and that of their children combined with emerging toxicologic evidence of adverse effects of phenoxy herbicides and TCDD, the National Academy of Sciences was asked to perform a comprehensive evaluation of scientific and medical information regarding the health effects of exposure to Agent Orange, other herbicides used in Vietnam, and the various components of those herbicides, including TCDD. Updated evaluations were conducted every two years to review newly available literature and draw conclusions from the overall evidence. Veterans and Agent Orange: Update 2014 is the final and cumulative report of the series.

Vibration Behavior in Ceramic-Matrix Composites (Advanced Ceramics and Composites #5)
by Longbiao LiThis book focuses on the vibration behavior of ceramic-matrix composites (CMCs), including (1) vibration natural frequency of intact and damaged CMCs; (2) vibration damping of CMCs considering fibers debonding and fracture; (3) temperature-dependent vibration damping of CMCs; (4) time-dependent vibration damping of CMCs; and (5) cyclic-dependent vibration damping of CMCs. Ceramic-matrix composites (CMCs) possess low material density (i.e., only 1/4 or 1/3 of high-temperature alloy) and high-temperature resistance, which can reduce cooling air and improve structure efficiency. Understanding the failure mechanisms and internal damage evolution represents an important step to ensure reliability and safety of CMCs. Relationships between microstructure, damage mechanisms, vibration natural frequency, and vibration damping of CMCs are established. This book helps the material scientists and engineering designers to understand and master the vibration behavior of CMCs at room and elevated temperatures.
