Energy efficient all-to-all broadcast in all-wireless networks
Information Sciences, 2010All-to-all broadcast is a communication pattern in which every node initiates a broadcast. In this paper, we investigate the problem of building a unique cast tree of minimum total energy, which we call Minimum Unique Cast (MUC) tree, to be used for all-to-all broadcast. The MUC tree is unoriented and unrooted.

All polymeric transducers for energy harvesting
2010 IEEE Sensors, 2010The power harvesting properties of a new class of all polymeric ionic electroactive materials, named Ionic Polymer-Polymer composites (IP2Cs) from vibrating sources are introduced and experimentally investigated. Obtained results show that the proposed technology gives better results with respect to other ionic polymeric transducers and allow to ...

All Digital Energy Sensing for Minimum Energy Tracking
IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2015Minimizing energy consumption is of utmost importance in an energy starved system with relaxed performance requirements. This brief presents a digital energy sensing method that requires neither a constant voltage reference nor a time reference. An energy minimizing loop uses this to find the minimum energy point and sets the supply voltage between 0.2

Almost All Functions Require Exponential Energy
2015One potential method to attain more energy-efficient circuits with the current technology is Near-Threshold Computing, which means using less energy per gate by designing the supply voltages to be closer to the threshold voltage of transistors. However, this energy savings comes at a cost of a greater probability of gate failure, which necessitates ...

Financing sustainable energy for all
UN Chronicle, 2013For the global community, universal sustainable energy must be a top priority. We owe it to the 1.1 billion people still living without electricity and the 2.9 billion people still using polluting biomass fuels for cooking and heating. Energy is fundamental to ending poverty as it underpins economic growth and progress in all areas of development–from ...

Chemical Physics Letters, 2012
Abstract In addition to the (ordinary) graph energy, which is directly related to the total π-electron energy, scores of other graph energies have been introduced in the last few years. We derive lower and upper bounds, applicable to any of these graph energies.

A High‐Energy Aqueous All‐Sulfur Battery
Angewandte ChemieAbstractRechargeable aqueous batteries are promising energy storage devices because of their high safety and low cost. However, their energy densities are generally unsatisfactory due to the limited capacities of ion‐inserted electrode materials, prohibiting their widespread applications. Herein, a high‐energy aqueous all‐sulfur battery was constructed

Per-call Energy Saving Strategies in All-to-All Communications
2011With the increase in the peak performance of modern computing platforms, their energy consumption grows as well, which may lead to overwhelming operating costs and failure rates. Techniques, such as Dynamic Voltage and Frequency Scaling (called DVFS) and CPU Clock Modulation (called throttling) are often used to reduce the power consumption of the ...
