distribution
Power flow calculation is very important to distribution system management, and more and more attention are paid to calculation speed and accuracy due to the booming smart grids which allow interconnection of distributed generation of different kinds.Because of different characteristic features of distribution networks, such as radial structure and high R/X ratio, distribution system load flow analysis differs significantly from transmission systems.

localequalisedwindowshift
This code applies local histogram equalization on an input image with a view to improve its contrast ratio. The image is read, converted to grayscale and resized with the inbuilt function of MATLAB. The window size may be changed, however, the window shift is as per size of the window. The output is definitely a better contrast image as compared to the input but checkerboard effect is evident.
