In this paper, we describe a method for joint supply, threshold voltage and sizing optimization, in presence of uncertain transistor parameters, to obtain robust energy-delay optimal designs. We extend our previous work on robust transistor sizing, which accounted for the added delay caused by transistor variations by adding margins on each gate delay proportional to the estimated delay variabi...

An interconnect joining a source and a sink is divided into xed length uniform width wire segments and some adjacent segments have bu ers in between The problem we considered is to simultaneously size the bu ers and the segments so that the Elmore delay from the source to the sink is minimized Previously no polynomial time al gorithm for the problem has been reported in literature In this paper...

Power loss and voltage uncertainty are the major issues prevalently faced in design of distribution systems. But such can be resolved through effective usage networking reconfiguration that has a combination Distributed Generation (DG) units from networks. In this point view, optimal placement sizing DGs ways to boost performance power The optimum allocation resolves various problems namely, lo...

The reactive-power service will be or is already obligatory for new grid-connected photovoltaic systems. The paper investigates the impact of the reactive-power service on the energy yield of a photovoltaic system and its effect on the inverter sizing and economic yield. Based on simulations and analysis of an operating photovoltaic system we show that energy losses due to the reactive-power se...

The paper highlights on a new method to solve the network reconfiguration problem. The uncertainty of system loads vary from time to time and makes the distribution system operation and control more complex. Thus for a feeder system power loss is not at its minimum. In this context a methodology to reconfigure the microgrid and also to facilitate its operation in autonomous mode is being discus...

The aim of lot sizing problems is to determine the periods where production takes place and the quantities to be produced in order to satisfy the customer demand while minimizing the total cost. Due to its importance on the efficiency of the production and inventory systems, Lot sizing problems are one of the most challenging production planning problems and have been studied for many years wit...
