The present project has the objective to model and simulate a special linear motor known as a Berdut linear motor. The motor’s governing equations are derived from Maxwell's equation and Newton's law of motion. These equations are coupled through the Lorenz force. Appropriate boundary conditions and initial conditions are also determined. This system does not have an exact solution. The set of ...

Abstract: Acoustic methods used in fish abundance estimation constitute a key part of the analytic assessment that makes the basis for abundance estimation of marine resources. The methods rely on power-budget equations and calibrated systems. Different formulations of power-budget equations and calibration factors have been proposed for use in scientific echo sounder and sonar systems. There a...

The adequacy of the existing design provisions for concrete-filled steel pipes subjected to axial forces and flexure is reviewed by comparing the strengths predicted by the CAN/CSA-S16.1-M94, AISC LRFD 1994, and the Eurocode 4 1994 codes and standards against experimental data from a number of investigators. New proposed design equations are then developed, in a format compatible with North Ame...
