GOALS Low-power systems often find the power cost of floating-point hardware prohibitively expensive. This research explores ways of reducing floating-point power consumption by minimizing the bitwidth representation of floating-point data. Analysis of several floating point programs that manipulate low-resolution human sensory data shows that these programs suffer no loss of accuracy even with...

single-phase squirrel cage and three-phase induction electromotors are the most popular electromotors used in industry from long ago. when an induction motor starts with direct connection method, it takes a lot of current from the power supply (several times the nominal current); so, several methods have been devised to start such electromotors. these methods either reduce the voltage of the st...

Abstract—The present work is an attempt to reduce the power loss and to improve the voltage profile on an existing 11 kV feeder by implementing different techniques. Simulations are performed using Mipower software on an existing 11 kV feeder (Aggarwal feeder) of industrial area Kapurthala. In this work effects of changing type of feeder are simulated to investigate the reduction in power loss ...

In this paper an EP and PSO based optimization algorithms have been proposed for solving optimal power flow problems with multiple objective functions. These algorithms take into consideration all the equality and inequality constraints. The improvement in system performance is based on reduction in cost of power generation and active power loss. The

In this paper, a combinational optimization algorithm is introduced to obtain the best size and location of Static Compensator (STATCOM) in power systems. Its main contribution is considering contingency analysis where lines outages may lead to infeasible solutions especially at peak loads and it commonly can be vanished by load-shedding. The objective of the proposed algorithm is firstly to pr...

This paper presents the comparative study of different crest factor reduction techniques such as Clipping, Block coding, Partial Transmit Sequences (PTS), Tone Reservation (TR) and Tone Injection, Selective Mapping, Interleaving, Active Constellation Extension (ACE) and Peak Windowing, clipping has been identified as the best technique for Peak-to-Average Power Ratio reduction as it does not re...

The attribute reduction algorithms based on neighborhood approximation usually use the distance as the approximate metric. Algorithms could result in the loss of information with the same distance threshold to construct the neighborhood families of different dimension spaces. Thereby, an attribute reduction algorithm based on hierarchical granulation is proposed. This algorithm can reduce redun...
