PSO Based on Cartesian Coordinate System
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 ...

Spherical Convolution Matched Layer in Cartesian Coordinate System for the FDTD Solver [PDF]
2020 IEEE 3rd International Conference on Electronic Information and Communication Technology (ICEICT), 2020 Spherical truncation boundary in non-spherical coordinate system for the finite-difference time-domain (FDTD) method is discussed in this paper. The convolutional perfectly matched layer has been optimized in non-physical division and enhanced weakly ability in absorbing evanescent wave.

Label System on Cartesian Coordinate by Using a Digital Camera
2010 International Conference on Internet Technology and Applications, 2010a novel image-based label system is proposed in this paper, we can convert the coordinate in image into Cartesian coordinate by using an image from a single CCD camera. This system could correspond arbitrary two points on the image convert to the actual distance no matter the digital camera is vertical to the measuring plane or not and the height of ...

Study on Gradation Fractal Cartesian Coordinate System of Asphalt Mixture
Advanced Materials Research, 2013In order to explore intrinsic relation of continuous, interlocked-dense and gap gradation, this paper studied them by fractal regression analysis, by which a gradation distribution Cartesian coordinate system was established and slope of the gradation was proposed at the same time.

Crossing rules in Cartesian and standard coordinate systems
Journal of Mathematical Physics, 1986A vectorial and a tensorial crossing rule are defined in Cartesian coordinate systems. Different applications are given. With a particular choice of the standardization coefficient of vectors the same expression of dot and vector products in the standard and Cartesian coordinate systems results.

An Intuitive Endoscope Operating System With an Interface Suitable for Cartesian Coordinate Input*
2023 45th Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2023Endoscopes are useful tools for inspecting and observing places that are inaccessible to humans and ordinary cameras. However, it is difficult to operate an endoscope intuitively because there is an embodiment difference between the endoscope and the human body.

Graphical model of an elastic medium in a cartesian coordinate system
Strength of Materials, 1993A discrete model of a deformable elastic body in the form of an oriented graph is examined. The graph can be used as a nontraditional means of deriving resolvent equations, involving the transformation of systems of generalized coordinates describing elements of the sectioned body to a coordinate system that describes the body as a whole.

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.

Discretization of Macroscopic Transport Equations on Non-Cartesian Coordinate Systems
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2007We discuss discretization schemes for the Poisson equation, the isothermal drift-diffusion equations, and higher order moment equations derived from the Boltzmann transport equation for general coordinate systems. We briefly summarize the method of dimension reduction when the problem does not depend on one coordinate.
