Robotic Arm Position Computing Method in the 2D and 3D Spaces

Actuators, 2023
This paper presents a method on how to compute the position of a robotic arm in the 2D and 3D spaces. This method is slightly different from the well-known methods, such as forward or inverse kinematics.

Polar Coordinate for Damage Imaging of Adhesively Bonded Plates Using Ultrasonic Guided Waves and Laser Doppler Vibrometer Measurements

IEEE Transactions on Instrumentation and Measurement, 2023
Wavefield measurements by a scanning laser Doppler vibrometer (LDV) are generally carried out in a Cartesian coordinate. As a piezoelectric transducer generates Lamb waves following radial paths, the use of a polar coordinate can be a suitable ...

New infinite families of Nth-order superintegrable systems separating in Cartesian coordinates [PDF]

Journal of Physics A: Mathematical and Theoretical, 2020
Abstract A study is presented of superintegrable quantum systems in two-dimensional Euclidean space E 2 allowing the separation of variables in Cartesian coordinates. In addition to the Hamiltonian H and the second order integral of motion X, responsible for the separation of variables, they allow a third integral that ...
