as there is a rapid growth both in the number of power consumers and also the limitations energy resources, it is clearly accepted that the old version of power grid must change into smart grid from head to toe. one of the most important advantages of smart grid which makes it much more exclusive rather than other typical systems is the two-way connectivity between the utility and the costumers...

We consider forward-link power allocation in a wireless network with stochastically varying data requests. We assume a user’s service preferences are specified via a utility function that depends on the received data rate. The allocation of power across users is studied, where this allocation may depend on both a user’s channel and utility. The objective is to maximize the time-averaged utility...

Background: In acutely unwell patients with rapidly changing renal function, estimating glomerular filtration rate (GFR) and predicting adverse renal outcomes are challenging and often inaccurate. Kinetic GFR (kGFR) is an estimate of immediate biomarker clearance derived from two discreet measurements that may better represent acute function. Our objective is to assess the clinical utility of k...

There is currently tremendous interest in deploying energyharvesting wireless sensor networks. Engineering such systems requires striking a careful balance between sensing performance and energy management. Our work addresses this problem through the design and analysis of a harvestingaware utility-based sensing rate allocation algorithm. Based on a network utility formulation, we show that our...

Live kidney donation is considered safe; nevertheless, data supporting such claims are almost exclusively of white origin with very limited long-term outcomes in ethnic minority donors. This prospective observational study consisted of a total of 103 previous kidney donors (54 black and 49 white) with mean follow-up days of 743.5 +/- 603.9 for white and 845.1 +/- 668.5 for black donors. The bla...

Multimedia services such as streaming live soccer over mobile and wireless networks might require a great deal of network resources and could be expensive for the consumer. In order to allocate resources optimally from both the network and the consumer perspectives. Therefore, it is important to be able to determine the utility of the stream as the match evolves. We investigate experimentally h...

Abstract— In this paper, we consider the rate control problem with the objective of maximizing the total user utility. It takes into account the possible differences in user requirements, and also provides a framework for achieving a wide range of fairness objectives. We propose a simple algorithm for achieving the optimal rates for this problem. The algorithm can be implemented in a distribute...
