Near-field linear sampling method for an inverse problem in an electromagnetic waveguide

Linear Sampling and Reciprocity Gap Methods for an Inverse Acoustic Problem in a Waveguide

We consider the problem of detecting bounded inhomogeneous obstacles in an infinite tubular waveguide. We have in mind the application of acoustic techniques to inspect underground pipes such as sewers: In this application a loud-speaker and microphone are lowered into a man-hole. Sound pulses are created in the pipe, and the acoustic field reflected by obstructions in the pipe is measured. Fro...

The Linear Sampling Method for Solving the Electromagnetic Inverse Scattering Problem

An inverse electromagnetic scattering problem for cavity

We consider the inverse electromagnetic scattering problem of determining the shape of a perfectly conducting cavity from measurement of scattered electric field due to electric dipole sources on a surface inside the cavity. We prove a reciprocity relation for the scattered electric field and a uniqueness theorem for the inverse problem. Then the near field linear sampling method is employed to...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Solving an Inverse Heat Conduction Problem by Spline Method

In this paper, a numerical solution of an inverse non-dimensional heat conduction problem by spline method will be considered. The given heat conduction equation, the boundary condition, and the initial condition are presented in a dimensionless form. A set of temperature measurements at a single sensor location inside the heat conduction body is required. The result show that the proposed meth...
