التباين المكاني و الزماني لتراكيز بعض العناصر الثقيلة في مياه الشرب في مدينة الحلة

Abstract EN

In our work, we have proposed a new transformation Biggs's self-scaling Quasi-Newton update which is based on the simple idea of approximation for the inverse Hessian matrix.

This transformation has implemented both theoretically and numerically and tested on some well-known test cases.

Numerical experiments indicate that this transformation is more effective than the standard BFGS-method.
