there area lot of mobile computer devices with a variety of applications and users tend to use them more. due to the limitations of mobile devices, running most of the procedures are impossible. to resolve this problem, mobile devices can be connected to the grid, to use the facilities of grid. on the other hand the communication mechanisms are different for each device and they cannot be conne...

Wind energy prediction has an important part to play in a smart energy grid for load balancing and capacity planning. In this paper we explore, if wind measurements based on the existing infrastructure of windmills in neighbored wind parks can be learned with a soft computing approach for wind energy prediction in the ten-minute to six-hour range. For this sake we employ Support Vector Regressi...

Grid applications need to be fault tolerant, malleable, and migratable. In previous work, we have presented orphan saving, an efficient mechanism addressing these issues for divide-and-conquer applications. In this paper, we present a mechanism for writing partial results to checkpoint files, adding the capability to also tolerate the total loss of all processors, and to allow suspending and la...

An increasing number of buildings are equipped with embedded sensing systems in order to capture what is happening within. These smart buildings process collected sensor data to increase user comfort and safety, cater for ambient assisted living, or help the residents save energy. However, saving energy is not always beneficial to the power grid, especially when renewable sources are present. M...

This work deals with the design of a Fuzzy Logic Control (FLC) based Energy Management System (EMS) for smoothing grid power profile grid-connected electro-thermal microgrid. The case study aims to an reduce impact on when renewable energy sources are incorporated pre-existing household appliances. scenario considers residential microgrid comprising photovoltaic and wind generators, flat-plate ...

Given a set of terminals in the plane, a rectilinear Steiner minimal tree is a shortest intercon-nection among these terminals using only horizontal and vertical edges. We present an algorithm that constructs a rectilinear Steiner minimal tree for any input terminal set. On a workstation, problems involving 20 input terminals can be solved in a few seconds, and problems involving 30 input termi...

The minute has given way to the second as an expression of radiographic exposure duration. It is predicted that the millisecond will be the term of the future. Arterial blood velocity exceeds 50 cm. per second. In cardiovascular radiography, especially angiocardiography, maximum detail cannot be achieved unless the x-ray exposure is short enough to "stop" rapid movement. Practical experience in...
