Energy for all in Africa — to be or not to be?!
Current Opinion in Environmental Sustainability, 2009Access to modern forms of energy continues to elude the majority of households in sub-Saharan Africa (SSA) and only about 30% of the population has access to electricity while 90% relies on traditional fuels for cooking and heating. The central question addressed in this review is whether or not SSA can provide access to modern energy services for its ...

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 ...

Catalysis: energy is the measure of all things
Chemical Communications, 2019Is there any place in the extremely well-established field of catalytic kinetics for new interpretations or novel models that can change the basic doctrines and viewpoints of catalytic cycles?

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

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.

Solar DC Homes: Energy for All
TENCON 2019 - 2019 IEEE Region 10 Conference (TENCON), 2019Energy is an essential resource for mankind. AC was the source of power distribution for the past two centuries, due to the ease of distributing it over a long distance employing transformers for stepping up and stepping down. Majority of the electronic home appliances uses DC source, which is obtained by converting the AC power from the grid. DC Power
