We describe a fast incremental method for power flows computation tailored for electric power markets. Fast in the sense that it can be used for real time power flows computation, and incremental in the sense that it computes any additional increase/decrease in line congestion caused by a particular (n-lateral) contract. Incremental methods offer a powerful way of dealing with congestion contin...

We introduce an on-line protocol which routes any set of N packets along shortest paths with congestion C and dilation D through an arbitrary network in O(C +D+log N) steps, with high probability. This time bound is optimal up to the additive log N , and it has previously only been reached for bounded-degree leveled networks. Further, we show that the above bound holds also for random routing p...

The analysis of IRS 1A satellite imagery has indicated the existence of two NE SW trending sub parallel faults along which the coast is undergoing land subsidence as revealed by the concavity in the shore line, preferential migration of the river systems and the drainage congestion, absence of beach ridges, occurrence of off shore shoal etc. The study has further indicated chains of tectonicall...

In this paper, with reference to congested multimodal urban networks, within-day dynamic traffic assignment is formalized as a fixed-point problem in terms of arc flow and transit frequency temporal profiles. The main innovation is to represent transit supply using a frequency approach, instead of a run approach, thus not requiring a diachronic graph. By so doing, intra and inter modal congesti...

Volume overload can be both the cause and effect of chronic kidney disease (CKD). Overhydration often accompanies renal insufficiency. In cardiovascular (CVD), fluid also function impairment. Beside salt restriction, loop diuretics are first-line therapy. Frequently developed resistance overcome by switching to intravenous administration, adding albumin alone or in combination with other diuret...
