audio codec, includes LPC,The code was tested on male and female speech files recorded using a microphone on my pc and also tested on the wavefiles of the TIMIT database. The results are found to be good enough. I have attatched 5 sample wavefiles, on which I have tested my code.

NUMERICAL OPTIMIZATION: This is steepest descent method with constant step length to find the minima of f(x, y) = xy exp(− 2x^2 − y^2 + 0.3y) Graphical represxentation in 5 ways of solution, simple and clear explained.

Distributed generation of electricity currently has a very important development. Several renewable and free energy sources like the wind (windmills), solar (photovoltaic or thermal) are increasingly used to produce electricity locally on remote sites. Because of the fickleness of the wind and light, energy management is one of the major challenges in wind power systems from the grid, as well as PV-diesel systems. We present in this paper, the design and implementation of an electronic load control module and optimal management of production for hybrid energy systems while ensuring the efficient.
