polluted its once primary water source, the Buriganga River. In the current scenario, waste management has become an essential factor. Both quantitative and qualitative disposal is absolutely crucial. In this study a new model of a waste power plant has been proposed which will require less manpower

Whether squeezing the last millijoule from your battery or operating a cooler CPU board, the goal is to burn less power. For many loads the power dissipation varies as the square of the applied voltage, so one approach is simply to minimize the supply voltage. Power dissipation equals V/R in a

Data center power consumption is growing to unprece-dented levels: the EPA estimates U.S. data centers will con-sume 100 billion kilowatt hours annually by 2011. Much of this energy is wasted in idle systems: in typical deployments, server utilization is below 30%, but idle servers still con

the knowledge of the sampling schedule of one's direct neighbors to use a wake-up preamble of minimized size. This scheme allows not only to reduce the transmit and the receive power consumption, but also brings a drastic reduction of the energy wasted due to overhearing. WiseMAC requires no set

...... Our computer systems need to do better at balancing useful performance with energy consumption. In a recent paper, Barroso and Hölzle 1 pointed out that most servers operate most of the time at relatively modest utilizations—seldom entirely idle, and seldom fully utilized. However, typical servers consume almost as much energy when idle as they do when fully loaded, so their energy efficiency (useful work per joule) suffers in their normal operating region. Barroso and Hölzle argued that designers should ‘‘develop machines that consume energy in proportion to the amount of work performed.’’

Abstract—Maximum power point tracking (MPPT) techniques are used in photovoltaic (PV) systems to maximize the PV array output power by tracking continuously the maximum power point (MPP) which depends on panels temperature and on irradiance conditions. The issue of MPPT has been addressed

Criticality concerns, decay heat management and radioactive waste handling are perceived as the primary, unsatisfactorily resolved technological problems of nuclear reactors. They all originate from very specific features of a fission phenomenon: self-sustained chain reaction in fissile materials

This paper explores the limits of microprocessor power savings available via certain classes of architecture-level optimization. It classifies architectural power optimizations into three categories, three sources of waste that consume energy. The first is the execution of instructions

demonstrated at the gate and system levels that large power savings are possible merely by cutting down on wasted power -- commonly referred to as power management. At the system level, this involves shutting down blocks of hardware that are not being used ([3], Chapter 10). Detection and shut down of unused

source of wasted power is speculation waste – waste due to speculative execution of instructions that do not commit their results. The third source is architectural waste. This comes from suboptimal sizing of processor structures. This study shows that when these sources of waste are eliminated
