This book was released on 2007-04-06 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The security of the U.S. commercial aviation system has been a growing concern since the 1970's when the hijacking of aircraft became a serious problem. Over that period, federal aviation officials have been searching for more effective ways for non-invasive screening of passengers, luggage, and cargo to detect concealed explosives and weapons. To assist in this effort, the Transportation Security Administration (TSA) asked the NRC for a study of emerging screening technologies. This report-the third of four-focuses on currently maturing millimeter-wavelength/terahertz imaging and spectroscopy technologies that offer promise in meeting aviation security requirements. The report provides a description of the basic operation of these imaging systems, an assessment of their component technologies, an analysis of various system concepts, and an implementation strategy for deployment of millimeter-wavelength/terahertz technology screening systems.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers the latest advances in the techniques employed to manage the THz radiation and its potential uses. It has been subdivided in three sections: THz Detectors, THz Sources, Systems and Applications. These three sections will allow the reader to be introduced in a logical way to the physics problems of sensing and generation of the terahertz radiation, the implementation of these devices into systems including other components and finally the exploitation of the equipment for real applications in some different field. All of the sections and chapters can be individually addressed in order to deepen the understanding of a single topic without the need to read the whole book. The THz Detectors section will address the latest developments in detection devices based on three different physical principles: photodetection, thermal power detection, rectification. The THz Sources section will describe three completely different generation methods, operating in three separate scales: quantum cascade lasers, free electron lasers and non-linear optical generation. The Systems and Applications section will take care of introducing many of the aspects needed to move from a device to an equipment perspective: control of terahertz radiation, its use in imaging or in spectroscopy, potential uses in security, and will address also safety issues. The text book is at a level appropriate to graduate level courses up to researchers in the field who require a reference book covering all aspects of terahertz technology.

Download or read book Introduction to THz Wave Photonics written by Xi-Cheng Zhang and published by Springer Science & Business Media. This book was released on 2009-12-01 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Terahertz (THz) radiation, which is electromagnetic radiation in a frequency int- val from 0.3 to 10 THz (1 mm–30 ?m wavelength), is the next frontier in science and technology. This band occupies a large portion of the electromagnetic sp- trum between the infrared and microwave bands. Basic research, new initiatives, and developments in advanced sensing and imaging technology with regard to the THz band remain unexplored compared to the relatively well-developed science and technology in the microwave and optical frequencies. Historically, THz technologies were used mainly within the astronomy c- munity for studying the background of cosmic far-infrared radiation, and by the laser-fusion community for the diagnostics of plasmas. Since the ?rst demonstration of THz wave time-domain spectroscopy in the late 1980s, there has been a series of signi?cant advances (particularly in recent years) as more intense THz sources and higher sensitivity detectors provide new opportunities for understanding the basic science in the THz frequency range.

Download or read book Strategies and Priorities for Information Technology at the Centers for Medicare and Medicaid Services written by National Research Council and published by National Academies Press. This book was released on 2012-02-23 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Centers for Medicare and Medicaid Services (CMS) is the agency in the Department of Health and Human Services responsible for providing health coverage for seniors and people with disabilities, for limited-income individuals and families, and for children-totaling almost 100 million beneficiaries. The agency's core mission was established more than four decades ago with a mandate to focus on the prompt payment of claims, which now total more than 1.2 billion annually. With CMS's mission expanding from its original focus on prompt claims payment come new requirements for the agency's information technology (IT) systems. Strategies and Priorities for Information Technology at the Centers for Medicare and Medicaid Services reviews CMS plans for its IT capabilities in light of these challenges and to make recommendations to CMS on how its business processes, practices, and information systems can best be developed to meet today's and tomorrow's demands. The report's recommendations and conclusions offered cluster around the following themes: (1) the need for a comprehensive strategic technology plan; (2) the application of an appropriate metamethodology to guide an iterative, incremental, and phased transition of business and information systems; (3) the criticality of IT to high-level strategic planning and its implications for CMS's internal organization and culture; and (4) the increasing importance of data and analytical efforts to stakeholders inside and outside CMS. Given the complexity of CMS's IT systems, there will be no simple solution. Although external contractors and advisory organizations will play important roles, CMS needs to assert well-informed technical and strategic leadership. The report argues that the only way for CMS to succeed in these efforts is for the agency, with its stakeholders and Congress, to recognize resolutely that action must be taken, to begin the needed cultural and organizational transformations, and to develop the appropriate internal expertise to lead the initiative with a comprehensive, incremental, iterative, and integrated approach that effectively and strategically integrates business requirements and IT capabilities.
Download or read book Security and Privacy written by John Kleinig and published by ANU E Press. This book was released on 2011-12-01 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study is principally concerned with the ethical dimensions of identity management technology - electronic surveillance, the mining of personal data, and profiling - in the context of transnational crime and global terrorism. The ethical challenge at the heart of this study is to establish an acceptable and sustainable equilibrium between two central moral values in contemporary liberal democracies, namely, security and privacy. Both values are essential to individual liberty, but they come into conflict in times when civil order is threatened, as has been the case from late in the twentieth century, with the advent of global terrorism and trans-national crime. We seek to articulate legally sustainable, politically possible, and technologically feasible, global ethical standards for identity management technology and policies in liberal democracies in the contemporary global security context. Although the standards in question are to be understood as global ethical standards potentially to be adopted not only by the United States, but also by the European Union, India, Australasia, and other contemporary liberal democratic states, we take as our primary focus the tensions that have arisen between the United States and the European Union.

This book was released on 2009-02-17 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new book from the National Research Council finds serious weaknesses in the government's plan for research on the potential health and environmental risks posed by nanomaterials, which are increasingly being used in consumer goods and industry. An effective national plan for identifying and managing potential risks is essential to the successful development and public acceptance of nanotechnology-enabled products. The book recommends a robust national strategic plan for addressing nanotechnology-related EHS risks, which will need to focus on promoting research that can assist all stakeholders, including federal agencies, in planning, controlling, and optimizing the use of engineered nanomaterials while minimizing EHS effects of concern to society. Such a plan will ensure the timely development of engineered nanoscale materials that will bring about great improvements in the nation's health, its environmental quality, its economy, and its security.

Download or read book Research Progress on Environmental Health and Safety Aspects of Engineered Nanomaterials written by National Research Council and published by National Academies Press. This book was released on 2013-12-25 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the increase in funding for research and the rising numbers of peer-reviewed publications over the past decade that address the environmental, health, and safety aspects of engineered nanomaterials (ENMs), uncertainty about the implications of potential exposures of consumers, workers, and ecosystems to these materials persists. Consumers and workers want to know which of these materials they are exposed to and whether the materials can harm them. Industry is concerned about being able to predict with sufficient certainty whether products that it makes and markets will pose any environmental, health or safety issues and what measures should be taken regarding manufacturing practices and worldwide distribution to minimize any potential risk. However, there remains a disconnect between the research that is being carried out and its relevance to and use by decision-makers and regulators to make informed public health and environmental policy and regulatory decisions. Research Progress on Environmental, Health, and Safety Aspects of Nanomaterials evaluates research progress and updates research priorities and resource estimates on the basis of results of studies and emerging trends in the nanotechnology industry. This report follows up the 2012 report A Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials, which presented a strategic approach for developing the science and research infrastructure needed to address uncertainties regarding the potential environmental, health, and safety risks posed by ENMs. This new report looks at the state of nanotechnology research, examines market and regulatory conditions and their affect on research priorities, and considers the criteria for evaluating research progress on the environmental, health, and safety aspects of nanotechnology.

This book was released on 2010-12-09 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasingly, the core mission of the Centers for Medicare and Medicaid Services (CMS), an agency of the Department of Health and Human Services, is expanding from one of focusing on prompt claims payment to one of becoming more broadly involved in improving health care quality and efficiency. The requirements for the information technology (IT) systems of CMS are changing as its mission changes, and the efforts to evolve its systems from those designed to support the agency's historical mission come in the midst of a push to modernize the nation's health care IT more broadly. These new challenges arise even as CMS must meet challenging day-to-day operational requirements and make frequent adjustments to its business processes, code, databases, and systems in response to changing statutory, regulatory, and policy requirements. In light of these and other emerging challenges, CMS asked the National Research Council to conduct a study that would lay out a forward-looking vision for the Centers for Medicare and Medicaid Services, taking account of CMS's mission, business processes, and information technology requirements. The study is being conducted in two phases. The first, resulting in the present volume, draws on a series of teleconferences, briefings, and an information-gathering workshop held in Washington, D.C., on September 27-28, 2010. The second phase, drawing on that workshop and on additional briefings, site visits, and committee deliberations, will result in a final report with recommendations, to be issued at the end of the project in 2011.
Download or read book A Research Strategy for Environmental Health and Safety Aspects of Engineered Nanomaterials written by National Research Council and published by National Academies Press. This book was released on 2012-06-09 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nanotechnology sector, which generated about $225 billion in product sales in 2009, is predicted to expand rapidly over the next decade with the development of new technologies that have new capabilities. The increasing production and use of engineered nanomaterials (ENMs) may lead to greater exposures of workers, consumers, and the environment, and the unique scale-specific and novel properties of the materials raise questions about their potential effects on human health and the environment. Over the last decade, government agencies, academic institutions, industry, and others have conducted many assessments of the environmental, health, and safety (EHS) aspects of nanotechnology. The results of those efforts have helped to direct research on the EHS aspects of ENMs. However, despite the progress in assessing research needs and despite the research that has been funded and conducted, developers, regulators, and consumers of nanotechnology-enabled products remain uncertain about the types and quantities of nanomaterials in commerce or in development, their possible applications, and their associated risks. A Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials presents a strategic approach for developing the science and research infrastructure needed to address uncertainties regarding the potential EHS risks of ENMs. The report summarizes the current state of the science and high-priority data gaps on the potential EHS risks posed by ENMs and describes the fundamental tools and approaches needed to pursue an EHS risk research strategy. The report also presents a proposed research agenda, short-term and long-term research priorities, and estimates of needed resources and concludes by focusing on implementation of the research strategy and evaluation of its progress, elements that the committee considered integral to its charge.
