Wave field synthesis (WFS) is an approach to the physical synthesis of sound fields over an extended receiver area by means of arrays of loudspeakers. The implementation of simple virtual source models like plane and spherical waves in WFS employs delays which are applied to the input signals. These delays can take values which are not equal to integer multiples of the sampling interval on a ti...

This paper proposes a novel technique for solving generation scheduling and ramp rate constrained unit commitment. A modified objective function associated with a new start-up cost term is introduced in this paper. The proposed method is used to solve generating scheduling problem satisfying SRR, minimum up and down time as well as ramp rate constraints. Two case studies are conducted to imp...
