Engineering for sustainability is an emerging theme for the twenty-first century,
and the need for more environmentally benign electric power systems is a critical
part of this new thrust. Renewable energy systems that take advantage of
energy sources that won’t diminish over time and are independent of fluctuations
in price and availability are playing an ever-increasing role in modern power
systems. Wind farms in the United States and Europe have become the fastest
growing source of electric power; solar-powered photovoltaic systems are entering
the marketplace; fuel cells that will generate electricity without pollution are
on the horizon. Moreover, the newest fossil-fueled power plants approach twice
the efficiency of the old coal burners that they are replacing while emitting only
a tiny fraction of the pollution.
There are compelling reasons to believe that the traditional system of large,
central power stations connected to their customers by hundreds or thousands of
miles of transmission lines will likely be supplemented and eventually replaced
with cleaner, smaller plants located closer to their loads. Not only do such distributed
generation systems reduce transmission line losses and costs, but the
potential to capture and utilize waste heat on site greatly increases their overall
efficiency and economic advantages. Moreover, distributed generation systems
offer increased reliability and reduced threat of massive and widespread power
failures of the sort that blacked out much of the northeastern United States in the
summer of 2003.
Dynamical Vision: ICCV 2005 and ECCV 2006 Workshops, WDV 2005 and WDV 2006, Beijing, China, October 21, 2005, Graz, Austria, May 13, 2006 Classical multiple-view geometry studies the reconstruction of a static scene observed by a rigidly moving camera. However, in many real-world applications the scene may undergo much more complex dynamical changes. For instance, the scene may consist of multiple moving objects (e.g., a traffic scene) or articulated motions (e.g., a walking human)...

Practical Palm Pre WebOS Projects (Beginning)
The Palm Pre is the hottest new device on the block. It’s the cell phone—nay, personal digital everything—that all the cool kids want to get their hands on . . . but no one wants to use it more than developers!
The Palm Pre is more than just a way-cool device, though: it is built on Palm’s brand-spanking-new...
