摘要:Abstract(#br)A method for reconstructing radially varying conductivity profiles in cylindrical conductors is described. Solenoidal driving and sensing coils surround the cylindrical sample and an AC magnetic field applied by the driving solenoid induces axisymmetric eddy currents...

摘要:Abstract(#br)By making multifrequency eddy current measurements on a layered conductor, it is possible to acquire information on the depth dependence of the conductivity. We consider an inversion problem in which coil impedance data are used to determine either the layer thicknes...

摘要:Abstract(#br)It has been argued that design and technology can be used as a vehicle for teaching science and vice versa. In this paper, we report an investigation into Grade 6 students’ understandings of concepts embodied in the Systems strand of a technology syllabus as the...

摘要:Abstract(#br)Teachers’ informed acceptance of challenges associated with teaching technology might ensure the successful implementation of a Technology syllabus in primary schools. They must be prepared to analyse their own understandings of technology concepts and processes...

摘要:In velocity and attenuation tomography, ray refraction leads to errors in time-of-arrival, as well as to errors in attenuationdue to phase cancellation and lateral beam displacement. Some authors have proposed iterative techniques based on numericalray tracing to correct for...
