In this paper, genetic algorithm-based approach for transient analysis of single transmission line connected to arrester is proposed. In this approach, the lightning channel striking the overhead line is first represented by a current source and this source is truncated by a finite set of frequency harmonies in time domain. Norton equivalent circuit viewed across arrester is then computed by me...

FermiCloud is a private cloud developed in Fermi National Accelerator Laboratory to provide elastic and on-demand resources for different scientific research experiments. The design goal of the FermiCloud is to automatically allocate resources for different scientific applications so that the QoS required by these applications is met and the operational cost of the FermiCloud is minimized. Our ...

The principle is shown for lightning protection of power distribution lines taking the effects of surge arresters, overhead ground wires and their combined use into consideration. Moreover an outline of a rational design method targeting direct lightning hits, induced overvoltages and backflow currents from high structures.

If the loop iterations of a loop nest cannot be partitioned into independent sets, the data communication for data dependences are inevitable in order to execute them on parallel machines. This kind of loop nests are referred to as Doacross loop nests. This paper is concerned with compiler algorithms for parallelizing Doacross loop nests for distributed-memory multicomputers. We present a metho...

Fixed cost: Includes all costs that do not vary with activity for an accounting period. Fixed costs are, at any time, the inevitable costs that must be paid regardless of the level of output and of the resources used. A Fixed Cost is therefore not an Opportunity Cost. Overhead is considered a fixed cost, even though it may vary somewhat according to the amount of activity. Any cost that does no...

We propose a method called Fast and Realistic Attacker Modeling and Evaluation (FRAME) that can reduce pessimism in static noise analysis by exploiting temporal logical correlation of attackers and using novel techniques termed envelopes and σ functions. Unlike conventional pruningbased approaches, FRAME efficiently considers all relevant attackers, thereby producing more realistic results. FRA...
