ASCENT: Adaptive self-configuring sensor networks topologies

by Alberto Cerpa, Deborah Estrin , 2004
"... Advances in microsensor and radio technology will enable small but smart sensors to be deployed for a wide range of environmental monitoring applications. The low per-node cost will allow these wireless networks of sensors and actuators to be densely distributed. The nodes in these dense networks w ..."

Therefore, nodes will have to self-configure to establish a topology that provides communication under stringent energy constraints. ASCENT builds on the notion that, as density increases, only a subset of the nodes

Power provisioning for a warehousesized computer,”

by Xiaobo Fan , Wolf-Dietrich Weber Luiz , André Barroso - ACM SIGARCH Computer Architecture News, , 2007
"... ABSTRACT Large-scale Internet services require a computing infrastructure that can be appropriately described as a warehouse-sized computing system. The cost of building datacenter facilities capable of delivering a given power capacity to such a computer can rival the recurring energy consumption ..."

budget with minimal risk of exceeding it. We use our modeling framework to estimate the potential of power management schemes to reduce peak power and energy usage. We find that the opportunities for power and energy savings are significant, but greater at the cluster-level (thousands of servers) than

Measuring and Reducing Energy Consumption of Network Interfaces in Hand-Held Devices

by Mark Stemm, Randy H. Katz , 1997
"... Next generation hand-held devices must provide seamless connectivity while obeying stringent power and size constrains. In this paper we examine this issue from the point of view of the Network Interface (NI). We measure the power usage of two PDAs, the Apple Newton Messagepad and Sony Magic Link, a ..."

Earth’s annual global mean energy budget

by J. T. Kiehl, Kevin E. Trenberth - Bull. Amer. Meteor. Soc , 1997
"... The purpose of this paper is to put forward a new estimate, in the context of previous assessments, of the annual global mean energy budget. A description is provided of the source of each component to this budget. The top-ofatmosphere shortwave and longwave flux of energy is constrained by satellit ..."

DRPM: Dynamic Speed Control for Power Management in Server Class Disks

by Sudhanva Gurumurthi, Anand Sivasubramaniam, Mahmut Kandemir, Hubertus Franke - In Proceedings of the International Symposium on Computer Architecture (ISCA , 2003
"... A large portion of the power budget in server environments goes into the I/O subsystem- the disk array in particular. Traditional approaches to disk power management involve completely stopping the disk rotation, which can take a considerable amount of time, making them less useful in cases where id ..."

Cess, James A. Coakley, Dominique A. H. Crommelynck, Leo Donner, Robert K, Michael D. King, Alvin J. Miller, Veerabhadran Ramanathan, David A. R, Larry L. Stowe, Ronald M. Welch
"... CERES objectives include the following. 1) For climate change analysis, provide a continuation of the Earth Radiation Budget Experiment (ERBE) record of radiative fluxes at the top-of-the-atmosphere (TOA), analyzed using the same techniques as the existing ERBE data. 2) Double the accuracy of estima ..."

Behavioral theories and the neurophysiology of reward,

by Wolfram Schultz - Annu. Rev. Psychol. , 2006
"... ■ Abstract The functions of rewards are based primarily on their effects on behavior and are less directly governed by the physics and chemistry of input events as in sensory systems. Therefore, the investigation of neural mechanisms underlying reward functions requires behavioral theories that can ..."

receptors that translate environmental energy and information into neural language. Thus, the functions of primary sensory systems are governed by the laws of mechanics, optics, acoustics, and receptor binding. By contrast, there are no dedicated receptors for reward, and the information enters the brain
