This paper has demonstrated that the Newton-Raphsin (NR) load flow technique can be stretched out to produce optimal (OPF) arrangement is achievable as for all significant disparity imperatives. These arrangements are frequently desired arranging and activity. We were examined how ought shared among different plants, when line misfortunes represented limit absolute activity cost with power comp...

this study was conducted during two years (2007-2009) in shawoor agricultural research station on a silty-clay soil. experiment conducted in split plots in a randomized complete blocks design in three replications. main plots were planting methods including centrifugal broadcaster (p1), centrifugal broadcaster + furrower (p2), seed drill (p3), seed drill + furrower (p4), three lines bed drillin...

This study is designed to consider the two important yet often neglected factors, which are factory recommendation and bit features, in optimum bit selection. Image processing techniques have been used to consider the bit features. A mathematical equation, which is derived from a neural network model, is used for drill bit selection to obtain the bit’s maximum penetration rate that corresponds ...
