Divide any circle’s circumference by its diameter and you get pi. But what, exactly, are its digits? Measuring physical ...

Abstract: Coupled linear delay time-varying differential-difference equations are considered. Explicit criteria for exponential stability of such equations are presented. The obtained results are used ...

Numbers, blocks, puzzles, rulers. Math is all around us every day. However, recent research by Suzanne Varnell, a graduate student in the Purdue University Department of Human Development and Family ...

ABSTRACT: Fractional-order time-delay differential equations can describe many complex physical phenomena with memory or delay effects, which are widely used in the fields of cell biology, control ...

This contribution proposes two third-order numerical schemes for solving time-dependent linear and non-linear partial differential equations (PDEs). For spatial discretization, a compact fourth-order ...
