according to this reality that iron bulks because of having ferromagnetic minerals, they have high magnetic intensity, in mining explorations most usual geophysical method  suggested to explore these resources is magnetic method. basically in order to process and interpretation of magnetic anomaly maps several methods be used of which most of these methods are based on try and error. one of usu...

In this paper, we present a new method to rigorously compute smooth branches of zeros of nonlinear operators f : R1 × B1 → R2 × B2, where B1 and B2 are Banach spaces. The method is first introduced for parameter continuation and then generalized to pseudo-arclength continuation. Examples in the context of ordinary, partial and delay differential equations are given.

OBJECTIVE To estimate 24-month continuation rates of all reversible contraceptive methods for women enrolled in the Contraceptive CHOICE Project. METHODS We analyzed 24-month data from the 9,256 participants enrolled in the Contraceptive CHOICE Project, a prospective observational cohort study that provides no-cost contraception to women in the St. Louis region. The project promoted the use o...

The correction equation in the Jacobi-Davidson method is effective in a subspace orthogonal to the current eigenvector approximation, while for the continuation of the process only vectors orthogonal to the search subspace are of importance. Such a vector is obtained by orthogonalizing the (approximate) solution of the correction equation against the search subspace. As an alternative, a varian...
