Standard numerical analysis tools, combined with elementary calculus, are deployed to evaluate a densely and wildly oscillatory integral proposed as a computational problem in the...
Integration of the currently available computing systems and platforms is one of the most envisaged goals achieved by computer scientists, which starts to become a reality nowaday...

The integration of complicated oscillatory functions arises in computational electromagnetics when evaluating signals produced by the propagation of electromagnetic radiation thro...
We treat the evaluation of a fixed-amplitude variable-phase integral of the form b a exp[ikG(x)]dx, where G (x) 0 and has moderate differentiability in the integration interval. ...
Abstract. We discuss the numerical evaluation of a symmetric potential function which arises naturally in applications. We present a method designed to accurately and efficiently c...
