Abstract: The so-called non-linear vector fitting (NL-VF) technique was recently introduced as a new method for rational function approximation in the frequency domain (FD). While the classical vector ...

Two methods are discussed which result in near minimax rational approximations to the exponential function and at the same time retain the desirable property that the approximation for negative values ...

This research was sponsored (in part) by the United States Air Force, Office of Scientific Research of the Air Research and Development Command, under Contract No. AF 18(600)-998. Note: The article ...

Although both rational choice theory and emotion provide some explanatory power for individual voting behavior, few studies to date have simultaneously examined the effects of rationality (cognition) ...

The stable or robust transfer of matter, information, or energy, from one point in space to another is a crucial scientific and technological challenge. In 1983, Nobel laureate D. J. Thouless proposed ...

This note describes a rational approximation for the error function which has been found useful in a subroutine as an asymptotic expression of improved accuracy ...

A mathematician has solved a 200-year-old maths problem after figuring out a way to crack higher-degree polynomial equations without using radicals or irrational numbers. The method developed by ...

ABSTRACT: The exponential transform or modified Fourier transform is an integral transform where the Kernel function is K a ( ξ,t )= a −iξt , and a∈] 1,+∞ [ . This is a general case of the Fourier ...

ABSTRACT: Harvard University was an important overseas training base for mathematical talents in modern China. In the early 20th century, a group of Chinese students went to Harvard University to ...
