Energy harvesting has received growing attention over the last decade. The research motivation in this field is due to the reduced power requirement of small electronic components, such as the wireless sensor networks used in structural health monitoring applications. The ultimate goal in this research field is to power such small electronic devices by using the vibration energy available in th...

In practical optimization, a priority requirement for different objectives of multiple objective optimization problems should be considered. In this paper, the distributed power management of a Virtual Power Plant (VPP) with priority requirement is optimized by the compromised method. The operation optimization model of VPP is formulated as a fuzzy multiple objective optimization problem consid...

The trade-offs discussed in the lecture are clear: increasing the inversion level improves speed and area requirement at the expense of increased power consumption. Working in weak inversion helps lower the power consumption but requires larger area and has poor performance in terms of speed. The moderate inversion region exhibits a compromise between speed and area consumption with very little...

Spectrum sharing with quality of service (QoS) requirement and power constraint on cognitive users is studied. The objective is to maximize the system throughput. This problem is modeled as a mixed integer nonlinear programming problem and then transformed to a continuous nonlinear programming problem through eliminating integer variables. We propose the joint power control and spectrum allocat...

A Smart Grid (SG) facilitates bidirectional demand-response communication between individual users and power providers with high computation and communication performance but also brings about the risk of leaking users' private information. Therefore, improving the individual power requirement and distribution efficiency to ensure communication reliability while preserving user privacy is a new...

A renewable energy source plays an important role in electricity generation. Various renewable energy sources like wind, solar, geothermal, ocean thermal, and biomass can be used for generation of electricity and for meeting our daily energy needs. Energy from the sun is the best option for electricity generation as it is available everywhere and is free to harness. On an average the sunshine h...

this paper surveys parallel scheduling problems and metrics correlated to and then applys metrics to make decision in comparison to other policy schedulers. parallel processing is new trend in computer science especially in embedded and multicore systems whereas needs more power consumption to reach speed up. the qos requirement for users is to have good responsiveness and for service providers...

Nano technology has vast applications such as microscopic robots or travel inside the body to deliver drug or do micro surgery. One major requirement to carry out such activity is power. Here in my paper, I have studied the possible sources of power supply from within the body and supply from outside the body, their merits and demerits. I have studied the various factors and different situation...

The use of doubly fed induction generator in wind power plants has result in new necessities to maintain a reliable operation of the network. The tendency of the grid codes is to require the ability from the wind power plant to keep connected during and after grid disturbance, similarly to the synchronous generators requirements. This paper analyse the behaviour of a wind power plant equipped w...

Colette’s essay was one of the most original of those submitted, taking the form of a law and literature review of one of the series of the infamous children’s books based around the young wizard Harry Potter. Colette’s essay appraises the detrimental effect a disregard for the doctrine of the separation of powers has in the wizarding community; the only negative remark from the judging panel w...
