METHODS A cross sectional study was conducted in two districts of N.W.F.P. namely Peshawar and Abbotabad from August 2007 up till January 2008. A total of 153 participants were(More)
The energy demand of residential end users has been so far largely uncontrollable and inelastic with respect to the power grid conditions. In this paper, we describe a scheme to solve multiple knapsack problems (MKP) using heuristic algorithms. Keeping total energy consumption of each household appliance under certain threshold with maximum benefit is(More)
