This book presents a comprehensive description of phonons and their interactions in systems with different dimensions and length scales. Internationally-recognized leaders describe theories and measurements of phonon interactions in relation to the design of materials with exotic properties such as metamaterials, nano-mechanical systems, next-generation electronic, photonic, and acoustic devices, energy harvesting, optical information storage, and applications of phonon lasers in a variety of fields. The emergence of techniques for control of semiconductor properties and geometry has enabled engineers to design structures in which functionality is derived from controlling electron behavior. As manufacturing techniques have greatly expanded the list of available materials and the range of attainable length scales, similar opportunities now exist for designing devices whose functionality is derived from controlling phonon behavior. However, progress in this area is hampered by gaps in our knowledge of phonon transport across and along arbitrary interfaces, the scattering of phonons with crystal defects, interface roughness and mass-mixing, delocalized electrons/collective electronic excitations, and solid acoustic vibrations when these occur in structures with small physical dimensions. This book providesa comprehensive description of phonons and their interactions in systems with different dimensions and length scales. Theories and measurements of phonon interactions are described in relation to the design of materials with exotic properties such as metamaterials, nano-mechanical systems, next-generation electronic, photonic, and acoustic devices, energy harvesting, optical information storage, and applications of phonon lasers in a variety of fields."
The aim of this volume is to make available to a large audience recent material in nonlinear functional analysis that has not been covered in book format before. Here, several topics of current and growing interest are systematically presented, such as fixed point theory, best approximation, the KKM-map principle, and results related to optimization theory, variational inequalities and complementarity problems. Illustrations of suitable applications are given, the links between results in various fields of research are highlighted, and an up-to-date bibliography is included to assist readers in further studies. Audience: This book will be of interest to graduate students, researchers and applied mathematicians working in nonlinear functional analysis, operator theory, approximations and expansions, convex sets and related geometric topics and game theory.
The book focuses on applications of belief functions to business decisions. Section I introduces the intuitive, conceptual and historical development of belief functions. Three different interpretations (the marginally correct approximation, the qualitative model, and the quantitative model) of belief functions are investigated, and rough set theory and structured query language (SQL) are used to express belief function semantics. Section II presents applications of belief functions in information systems and auditing. Included are discussions on how a belief-function framework provides a more efficient and effective audit methodology and also the appropriateness of belief functions to represent uncertainties in audit evidence. The third section deals with applications of belief functions to mergers and acquisitions; financial analysis of engineering enterprises; forecast demand for mobile satellite services; modeling financial portfolios; and economics.

Our national security increasingly depends on access to the most sophisticated and advanced technology. Yet, the next time we set out to capture a terrorist leader we may fail. Why? The answer lies in a conflict between two "worlds." One is the dynamic, global, commercial world with its thriving innovation landscape. The other is the world of national security, in which innovation is a matter of life or death. The conflict is about secrecy. Innovating in a Secret World is a detailed examination of the U.S. government and innovation landscapes and the current trends in national security-related research and development (R&D), so often secret. Author and researcher Srivastava evaluates whether the execution of technology innovation strategy in that world is unintentionally leaving certain innovations behind or is unintentionally precluding certain classes of innovators from participating. She identifies the unintended consequences and emergent behaviors that result. This unfolds in a complex, dynamic system that includes the legal framework in which technology innovation must exist. Srivastava suggests an emerging class of R&D strategy called open innovation-a strategy that pertains to broadening participation in innovation beyond an individual organization or division traditionally assigned to perform R&D activities. Through compelling stories of commercial and early government applications, Srivastava shows how open technology innovation strategies are promising and potentially advantageous in enabling, accelerating, and enhancing technology innovation. If open innovation could be successfully applied to closed U.S. government R&D, the benefits to national security and global leadership would be profound.
Agriculture is one of the most climate-sensitive of all economic sectors. In many countries, such as the four examined in Looking Beyond the Horizon, the risks of climate change are an immediate and fundamental problem because the majority of the rural population depends either directly or indirectly on agriculture for its livelihood. The risks of climate change to agriculture cannot be effectively dealt with-hand the opportunities cannot be effectively exploited-without a clear plan for aligning agricultural policies with climate change, developing the capabilities of key agricultural institutions, and investing in infrastructure, support services, and on-farm improvements. Developing such a plan ideally involves a combination of high-quality quantitative analysis; consultation with key stakeholders, particularly farmers and local agricultural experts; and investments in both human and physical capital. The diverse experiences of Albania, the former Yugoslav Republic of Macedonia, Moldova, and Uzbekistan, highlighted in this book, show that it is possible to develop a plan to meet these objectives-one that is comprehensive and empirically driven as well as consultative and quick to develop. The approach of this volume is predicated on strong country ownership and participation, and is defined by its emphasis on 'win-win' or 'no regrets' solutions to the multiple challenges posed by climate change for the farmers of Eastern Europe and Central Asia. The solutions are measures that increase resilience to future climate change, boost current productivity despite the greater climate variability already occurring, and limit greenhouse gas emissions-also known as 'climate-smart agriculture'. Looking Beyond the Horizon draws on the experiences of applying this approach to these four nations in Eastern Europe and Central Asia with the goal of helping each country mainstream climate change adaptation into its agricultural policies, programmes, and investments. The book also highlights the projected impacts of climate change on agriculture in these countries through forecast variations in temperature and rainfall patterns, which are crucial to farming, and offers a map for navigating the risks and realising the opportunities. Finally, a detailed explanation of the approach, as well as lessons learned from its implementation, is provided for those who would like to implement similar programmes in other countries of Europe, Central Asia, or anywhere else in the world.
This book illustrates the World Bank s commitment to assist countries to respond to the opportunities and challenges posed by climate change. Undertaken in collaborative partnership with policy makers, farmers, civil society, and other stakeholders in Armenia, Azerbaijan and Georgia, it provides a much needed response to the call for action by quantifying the impact and identifying key priorities for policies, programs, and investments to reduce the vulnerability of agricultural systems to climate change in the South Caucasus. The study responds to the urgent need for climate adaptation, as highlighted in the World Bank s Turn Down the Heat report. Notably, the South Caucasus is already contending with increasing aridity and more frequent extreme weather events (e.g. severe droughts, floods and hailstorms). It presents practical solutions for a more climate smart agriculture, at the regional, national and agro-ecological zone level in each country. The recommendations offered in this book are a compilation of the results of the three national studies, and highlight the need and potential for regional collaborative action to increase benefits, while also continuing to emphasize the need for an effective response at the national level. The national level results are supported by country reports, which provide more details. This work is but an important beginning. To achieve the goals of climate resilience in the agriculture sector, more work is needed to translate the proposals into reality. The analysis demonstrates that investments in irrigation infrastructure and on-farm technologies have great potential to raise agricultural productivity and improve the climate resilience of the sector. Demand-side agricultural water management will have high short-term payoffs, and these short-term payoffs are complementary to the success of long- term irrigation, drainage and other infrastructure investments. Strengthening the disaster risk management strategies (beyond agricultural measures) are also needed to help mitigate household risks from extreme events, especially for the poorest, who are the most vulnerable."
