书籍 New Horizons in Mobile and Wireless
European Research Framework Programs are a public policy instrument to
strengthen European competitiveness through cooperation. Although they have a
fixed timeframe, determined research themes, and specific expected impact, the
achievements in research and development (R&D) made by the funded projec ...
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 Thin Film Metal-Oxides
 This chapter surveys the high temperature and oxygen partial pressure
behavior of complex oxide heterostructures as determined by in situ synchrotron
X-ray methods. We consider both growth and post-growth behavior, emphasizing
the observation of structural and interfacial defects relevant to t ...
