An introductory, graduate-level look at modern communications in general and radio communications in particular. This seminal presentation of the applications of communication theory to signal and receiver design brings you valuable insights into the fundamental concepts underlying today's communications systems, especially wireless communications. Coverage includes: AM, FM Phase Modulation, PCM, fading, and diversity receivers. This is a classic reissue of a book published by McGraw Hill in 1966.
This book is concerned with such questions as the following: What is the life of the past in the present? How might “the theatre of death” and “the uncanny in mimesis” allow us to conceive of the afterlife of a supposedly ephemeral art practice? How might a theatrical iconology engage with such fundamental social relations as those between the living and the dead? Distinct from the dominant expectation that actors should appear life-like onstage, why is it that some theatre artists – from Craig to Castellucci – have conceived of the actor in the image of the dead? Furthermore, how might an iconology of the actor allow us to imagine the afterlife of an apparently ephemeral art practice? This book explores such questions through the implications of the twofold analogy proposed in its very title: as theatre is to the uncanny, so death is to mimesis; and as theatre is to mimesis, so death is to the uncanny. Walter Benjamin once observed that: “The point at issue in the theatre today can be more accurately defined in relation to the stage than to the play. It concerns the filling-in of the orchestra pit. The abyss which separates the actors from the audience like the dead from the living...” If the relation between the living and the dead can be thought of in terms of an analogy with ancient theatre, how might avant-garde theatre be thought of in terms of this same relation “today”?
Mobile and wireless communications applications have a clear impact on improving the humanity wellbeing. From cell phones to wireless internet to home and office devices, most of the applications are converted from wired into wireless communication. Smart and advanced wireless communication environments represent the future technology and evolutionary development step in homes, hospitals, industrial, vehicular and transportation systems. A very appealing research area in these environments has been the wireless ad hoc, sensor and mesh networks. These networks rely on ultra low powered processing nodes that sense surrounding environment temperature, pressure, humidity, motion or chemical hazards, etc. Moreover, the radio frequency (RF) transceiver nodes of such networks require the design of transmitter and receiver equipped with high performance building blocks including antennas, power and low noise amplifiers, mixers and voltage controlled oscillators. Nowadays, the researchers are facing several challenges to design such building blocks while complying with ultra low power consumption, small area and high performance constraints. CMOS technology represents an excellent candidate to facilitate the integration of the whole transceiver on a single chip. However, several challenges have to be tackled while designing and using nanoscale CMOS technologies and require innovative idea from researchers and circuits designers. While major researchers and applications have been focusing on RF wireless communication, optical wireless communication based system has started to draw some attention from researchers for a terrestrial system as well as for aerial and satellite terminals. This renewed interested in optical wireless communications is driven by several advantages such as no licensing requirements policy, no RF radiation hazards, and no need to dig up roads besides its large bandwidth and low power consumption. This second part of the book, Mobile and Wireless Communications: Key Technologies and Future Applications, covers the recent development in ad hoc and sensor networks, the implementation of state of the art of wireless transceivers building blocks and recent development on optical wireless communication systems. We hope that this book will be useful for students, researchers and practitioners in their research studies.
Each year thousands of biomedical and behavioral researchers submit grant applications to the United States Public Health Service (USPHS) for support of their research or research training activities. The majority of these applications are submitted to the National Institutes of Health (NIH). By describing the inner workings of the NIH extramural programs and providing practical information about grant programs and processes, this authoritative work is designed to help investigators gain a more favorable edge in obtaining support for their research proposals. It offers practical insights into a broad spectrum of the basic and clinical research interests of the 21 NIH research granting components, and identifies the various mechanisms of support. Descriptions, guidance, and advice are also provided on specific areas such as how to prepare a grant application; the peer review system, the procedures leading to award decisions, the responsibilities of the NIH staff in managing the review and referral of applications, and managing grant programs. Other extramural policies and procedures are covered such as the appeals system, animal welfare, the privacy act, and research involving human subjects. Legislation, funding, and the NIH budget are also discussed. Written by two former senior-level managers at the National Institutes of Health and current consultants to several USPHS agencies, ^IA Guide to NIH Grant Programs^R is a valuable reference source for members of the biomedical and behavioral research community.

This dissertation focuses on the application of Tip-Enhanced Raman spectroscopy (TERS) to non-transparent and non-conductive samples, allowing for the optical characterization of nanoelectronic devices. As such, nano-crystals are analyzed as a model system for the investigation of chemical and structural properties. Furthermore, a novel method for mapping the refractive index of materials with nanometer resolution is presented. The technological progress of electronics through miniaturization has reached the nanoscale while new materials with high performance and functional properties gain importance. Quality control and the scientific understanding of size effects in electronic nanostructures are required more than ever to consolidate existing technologies and to determine scaling limits of new materials. Conventional techniques, including scanning electron and scanning probe microscopy, provide topographic information but only very limited chemical information to analyze the physical properties of nanomaterials. Chemical and structural sensitivity is available by Raman or infrared spectroscopy, but with a spatial resolution limited to the microscale by the diffraction limit of light. TERS combines the virtues of scanning probe microscopy with those of optical spectroscopy to overcome the diffraction limit through the excitation of surface plasmons on a scanning probe tip to confine light to nanometers. In this work, a TERS system was installed to operate on opaque samples by employing optical side access. TERS probes were fabricated by electrochemical etching and operated in scanning tunneling microscopy and atomic force microscopy with quartz tuning forks to enable scanning on various surfaces. TERS was then applied to ferroelectric lead titanate nano-crystals on a platinized silicon substrate as a model system for nanostructured, charge-based memory devices at the onset of finite size effects.
Since the birth of their nation, Americans have acted on the belief that theirs was a land of youth, a place destined to offer a fresh start to an aging world. No Country for Old Age tells this story from the founding period to our present moment, but not without exposing its darker side: rejuvenation has often bred grand expectations that end in division and despair. Mischa Honeck reveals how Americans of diverse backgrounds have sought not only to feel and look younger but also to breathe new life into their communities. Whether marching under the banners of science, public health, sexual liberation, physical fitness, nation-building, or world peace, these youth seekers have tended to paint their ventures in utopian colors. However, from the founders to today's Silicon Valley elites, anti-aging ventures have repeatedly magnified social inequalities, often projecting visions of society that have been unmistakably classist, racist, misogynist, and ageist. Today we are experiencing rejuvenation's Janus-faced legacy: As transhumanists rhapsodize about cyber-enhancing human bodies, ghastly pandemics, old-age poverty, and shrinking life expectancies are poised to become the new normal for many twenty-first-century Americans.
