One of the perennial challenges of building robots is minimizing the size and weight of drive systems while preserving power.

AC induction motors are everywhere, from ceiling fans to vehicles. They’re reliable, simple, and rugged — but there are some disadvantages. It’s difficult to control the speed ...

The information in this workshop is taken from my notes from a course at Tom Brown's Tracking School in New Jersey, in a course taught by John Stokes of the Tracking Project, and from my personal ...

Materials science is an interdisciplinary field concerned with the understanding and application of the properties of matter. Materials scientists study the connections between the underlying ...

Abstract: The effect of the field current and commutation angle parameters on average torque of doubly salient electromagnetic motor (DSEM) is highly mutual coupled at high-speed operation. Hence, it ...

Abstract: Migrated dip-angle gathers provide a visible domain for estimating Fresnel zones of migration. However, it remains a challenge to extract Fresnel zones from the dip-angle gathers with higher ...

Objective: To evaluate the effects of lumbosacral and lumbopelvic fixation and fusion on hip motor function using a three-dimensional gait analysis system. Methods: This single-center prospective ...
