One of the most remarkable basis of the gravity data inversion is the recognition of sharp boundaries between an ore body and its host rocks during the interpretation step. Therefore, in this work, it is attempted to develop an inversion approach to determine a 3D density distribution that produces a given gravity anomaly. The subsurface model consists of a 3D rectangular prisms of known sizes ...

David C. Shallcross, University of Melbourne, Melbourne, Victoria 3010, Australia [email protected] Abstract  This paper describes a series of activities for the senior secondary mathematics class room which have been developed to illustrate how mathematics is used by engineers. In one example students are presented with an innovative design for a single storey underground car park. The cl...

An inversion equation takes the Cartesian coordinates of a point on a parametric curve or surface and returns the parameter value(s) of that point. A 2-D curve inversion equation has the form t = f(x, y)/g(x, y). This paper shows that practical insight into inversion can be obtained by studying the geometry of the implicit curves f(x, y) = 0 and g(x, y) = 0. For example, the relationship betwee...
