Imaginary Points in Cartesian Coordinate System
Geometry & Graphics, 2019Geometric models are considered that allow symbolic representation of imaginary points on a real Cartesian coordinate plane XY. The models are based on the fact that through every pair of imaginary conjugate points A~B with complex coordinates x = a ± jb, y = c ± jd one unique real line m passes. For the image of imaginary points, it is proposed to use

PSO Based on Cartesian Coordinate System
International Conference on Intelligent Computing, 2014In order to deal with the problems of the slow convergence and easily converging to local optima, a classification learning PSO is proposed based on hyperspherical coordinates. The method of determination of poor performance particle is presented, and the swarm is divided into three parts where three learning strategies are introduced to improve the ...

A Cartesian Coordinate Algorithm for Power System State Estimation
IEEE Transactions on Power Apparatus and Systems, 1983This paper presents a new steady-state estimator based on the Cartesian coordinate formulation of nodal and line flow equations and minimization of weighted least squares (WLS) of the residuals. The fact that the rectangular coordinate version of network Performance equations is completely expressible in a Taylor series and contains terms up to the ...

Spatial triangulation in a local, astronomical oriented cartesian coordinate system [PDF]
Bulletin géodésique, 1969 For the determination of spatial coordinates of the points of a net-work a local Cartesian coordinate system is introduced, whoze z-axis coincides with the true vertical of an arbitrarily selected central point in the net-work, and whose x-axis is oriented to astronomical north. The observed horizontal directions and vertical angles, which refer to the

The Application of the Mega-Dimensional Cartesian Coordinate System in the Economic Policy Modeling
SSRN Electronic Journal, 2008This paper is interested to study the different types and dimensions of graphs applied on the graphical visualization of economic policy modeling. Finally, this paper proposes the uses of multi-dimensional graphs under the application of the Mega-Space Cartesian Coordinate System in the economic policy modeling.

Self-Tuning Manipulator Control in Cartesian Base Coordinate System
Journal of Dynamic Systems, Measurement, and Control, 1985A discrete-time stochastic model for the motion of a robotic manipulator system is introduced. The input vector consists of the voltages to the joint motors, and the output vector has the velocities (positions) of the gripper expressed in the world (xyz) coordinate system as the components.

Origamic Architecture in the Cartesian Coordinate System
, 2009 The study of mathematics in origamic architecture (OA) has not been widely practised. In this present study, we attempt to reveal the spatial geometrical elements in OA.
