that the energy savings increase with the number of levels in the hierarchy. Results in stochastic geometry are used to derive solutions for the values of parameters of our algorithm that minimize the total energy spent in the network when all sensors report data through the clusterheads to the processing center.

ABSTRACT Over the last 30 years, the U.S. Department of Energy (DOE) has successfully and safely transported shipments of spent nuclear fuel over America's highways and railroads. During that time, an exemplary safety record has been established with no identifiable fatalities, injuries

station, thus reducing the amount of energy spent per round. Simulation results show that PEGASIS performs better than LEACH by about 100 to 200 percent when 1 percent, 25 percent, 50 percent, and 100 percent of nodes die for different network sizes and topologies. For many applications, in addition

assured by a service-level agreement (SLA). Power consumption of these servers is becoming a serious concern in the design and operation of the hosting centers. The effects of high power consumption manifest not only in the costs spent in designing effective cooling systems to ward off the generated heat

with the distance of the link, the link cost is higher for longer hops; the energy-aware routing algorithms select a path with a large number of small-distance hops. In this paper, we argue that such a formulation based solely on the energy spent in a single transmission is misleading --- the proper metric should

A tomographic method, using algebraic reconstruction methods, has been examined for verification of the integrity of spent nuclear fuel. Computer simulations were performed where fuel rods have been removed, i.e. water filled, or replaced with fuel-like material. Various geometric patterns

Introduction High energy and large intensity of beams in the linear collider TESLA [1] require a careful study of how to dispose both electron and positron beams after collision. To minimize uncontrollable activation of the collider equipment the beams are transferred to a dump foreseen
