书籍 Wireless+Multi-Antenna+Channels+Modeling
The explosion in demand for wireless services experienced over the past 20 years
has put significant pressure on system designers to increase the capacity of the
systems being deployed. While the spectral resource is very scarce and practically
exhausted, the biggest possibilities are predicted to b ...
书籍 Wireless-Based+Software+Systems
The wide deployment of wireless networks and mobile technologies, along with the
significant increase in the number of mobile device users, have created a very strong
demand on various wireless-based, mobile-based software application systems and
enabling technologies. This not only provides many ne ...
书籍 Value+Driven+Product+Planning+and+Systems
The “bottom-line” metrics of cash flow, demand, price, and return on investment
are driven by a second set of financial metrics represented by value to the
customer, cost, and the pace of innovation. Get them right relative to competition
and impressive bottom-line results should follow. Because o ...

n its Framework and Roadmap for Smart Grid Interoperability Standards, the US
National Institute of Standards and Technology declares that a twenty-first-century
clean energy economy demands a twenty-first-century electric grid. 1 The start of the
twenty-first century marked the acceleration of the ...
书籍 Electric+Distribution+Network+Planning
Electric distribution networks are critical parts of power delivery systems. In recent
years, many new technologies and distributed energy resources have been inte-
grated into these networks. To provide electricity at the possible lowest cost and at
required quality, long-term planning is essential ...
书籍 Intelligent+Microgrid+Management
A modern power grid needs to become smarter in order to provide an affordable,
reliable, and sustainable supply of electricity. For these reasons, a smart grid is
necessary to manage and control the increasingly complex future grid. Certain
