"If you've been searching for a way to get up to speed on IEEE 802.11n and 802.11ac WLAN standards without having to wade through the entire specification, then look no further. This comprehensive overview describes the underlying principles, implementation details and key enhancing features of 802.11n and 802.11ac. For many of these features the authors outline the motivation and history behind their adoption into the standard. A detailed discussion of key throughput, robustness, and reliability enhancing features (such as MIMO, multi-user MIMO, 40/​80/​160 MHz channels, transmit beamforming and packet aggregation) is given, plus clear summaries of issues surrounding legacy interoperability and coexistence. Now updated and significantly revised, this 2nd edition contains new material on 802.11ac throughput, including revised chapters on MAC and interoperability, plus new chapters on 802.11ac PHY and multi-user MIMO. An ideal reference for designers of WLAN equipment, network managers, and researchers in the field of wireless communications""

"This book provides a broad introduction to Cognitive radio, which attempts to mimic human cognition and reasoning applied to software defined radio and reconfigurable radio over wireless networks. It provides readers with significant technical and practical insights into different aspects of Cognitive radio, starting from a basic background, the principle behind the technology, the inter-related technologies and application to cellular and vehicular networks, the technical challenges, implementation and future trends. The discussion balances theoretical concepts and practical implementation. Wherever feasible, the different concepts explained are linked to application of the corresponding scheme in a particular wireless standard."

"Today's young people are the next generation of workers, entrepreneurs, parents, active citizens and leaders. This report discusses the priorities for government action across five youth transitions that shape investments in young people's human capital: learning, working, staying healthy, forming families, and exercising citizenship."

"In the face of the recent financial crisis there is increased focus on long-term investment strategies. This is particularly true for institutional investors who manage our retirement savings. Simultaneously there is increased demand that financial assets be invested with an understanding of long-term environmental and social sustainability. Responsible investing provides a long-term sustainable investment strategy that values environmental, social and governance (ESG) factors in investment decision-making. Responsible Investing has always had a broad mandate. Put simply, it is a long-term sustainable investment strategy that seeks to reduce risk in investment portfolios through managing ESG issues in today’s corporations. The next generation of responsible investment explores this topic in an edited volume intended for those with an interest in finance and business."

"This book presents new concepts for a next generation of PV. Among these concepts are : multijunction solar cells, multiple excitation solar cells (or how to take benefit of high energy photons for the creation of more than one electron hole-pair), intermediate band solar cells (or how to take advantage of below band-gap energy photons) and related technologies (for quantum dots, nitrides, thin films), advanced light management approaches (plasmonics).

"This article examines the relationship between career system and ability developmentof candidates for next generation business managers. Two research questionsare set, and they are as follows; 1) Are there abilities unique to business managersthose are irrelevant to any specific function and those are not expected byIntellectual Skills Theory? If they are, then their contents and development processshould be identified. 2) Do the candidates pursue their specialists' careers with wideranging careers or develop their generalists' one through multi-functional jobs experiencesamong which there is no complementarity, or both of the two exist? An interviewresearch on the relationship between the learning contents through the 22candidates' careers in a large electronic component company and opportunities tolearn is conducted for the purpose of finding the answers to the two research questions.The results are as follows; The 129 learning contents are found and almost twothirds of the contents are abilities irrelevant to a specific function such as managerialone in spite of their wide range careers within one or two functions. Identified managerialabilities are for coordinating with other departments, understanding situationsof entirety of their firm, judging based on their firm's strength and weakness, andbearing trust from other employees and networks within their firm. The process ofmastering management abilities identified in this research is analogical learning basedon comparison that is triggered by difference recognition to their work triggered bya personnel move. And this process is not expected by Intellectual Skills Theory.Then the concurrent learning hypothesis is proposed that recognition of differencetriggers by a personnel move encourages two types of learning. One of those iscause-effect learning that develops uncertainty processing ability unique to a specificjob which is supposed by Intellectual Skills Theory, and the other is analogical learningbased on comparison between the two jobs that a personnel move brings in thatis not relevant to any specific function."
