Centering Relationships, Active Teaching, and Career Development in One STEM Teaching Practicum

New Directions for Community Colleges, EarlyView.
ABSTRACT Broadening participation in STEM fields, particularly among underrepresented minority (URM) groups, has long been a national priority (AIR 2013; The Education Trust 2024). Community colleges—by virtue of their open access, diverse student populations, and teaching‐focused missions—are uniquely positioned to contribute to this effort.

Characteristic of eddy current on the secondary of eddy current brake

1997 IEEE International Electric Machines and Drives Conference Record, 2002
An eddy current brake is a new assistance brake system of a large scale vehicle, and the eddy current plays an important role in the braking force of this brake. This paper presents a new calculating method based on the experiment, while the eddy current problem, generally, is calculated by using FEM.

Experiments with eddy currents: the eddy current brake

European Journal of Physics, 2004
A moderate-cost experimental setup is presented to help students to understand some qualitative and quantitative aspects of eddy currents. The setup operates like an eddy current brake, a device commonly used in heavy vehicles to dissipate kinetic energy by generating eddy currents. A set of simple experiments is proposed to measure eddy current losses

Computation of 2D and 3D Eddy Currents of Eddy Current Retarders

2010 International Conference on Electrical and Control Engineering, 2010
this paper deals with the A-_-A formulation applied to problems where motion is the source of eddy currents. The Lorenz gauge is used to ensure uniqueness of the solution and leads to a two-step computation procedure: A is computed first followed by _ on moving regions only.

Eddy current sensor simulation

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2017
Purpose This paper aims to present a simulation concept and an experimental verification of a novel sensor design for the shaft position measurement based on the eddy current principle and the phase-shift measurement. The simulation method for the sensor characteristic determination is presented.

Formulation of the eddy-current problem

IEE Proceedings A (Physical Science, Measurement and Instrumentation, Management and Education), 1990
A critical survey on some of the principal approaches to the solution of the general three-dimensional eddy-current problem is presented. The two main families of formulations, those magnetic and those electric, are discussed, with reference to both mathematical and computational aspects.
