The first theoretical models of the propagation of an electromagnetic field in a waveguide date back to the second half of the 19th century (Hertz, Debye, Rayleigh). The technological fallout for long ...

This application note presents space vector control or field-oriented control (FOC) using polar coordinates. It is used for controlling 3-phase alternating current induction motors (ACIM). The ...

Understanding polarization, polarization control and waveplates can be a daunting task. Emily Kubacki from CVI Laser describes the how, why and what of waveplates. Even after grasping the theory ...

A general approach to the k-sample problem for continuous random variables, based on a generalization of Pearson's classical φ 2 measure, is presented. Tests are developed by considering an analysis ...
