* Locate points in a plane by using polar coordinates. * Convert points between rectangular and polar coordinates. * Sketch polar curves from given equations. * Convert equations between rectangular ...

Provides functions to convert geocentric Cartesian coordinates, latitude and longitude, plane rectangular coordinates, and pixel coordinates. It also defines a structure to represent each coordinate ...

Abstract: This paper explores solutions to linearized power-flow equations with bus-voltage phasors represented in rectangular coordinates. The key idea is to solve for complex-valued perturbations ...

Abstract: This paper presents some improvements to the load flow solution in rectangular coordinates. First, in an attempt to use as linear a model as possible, both the nodal equations and the bus ...
