A bstract We investigate the effect of superradiant scattering gravitational perturbations on stability rotating black strings, focusing six dimensional equal-spinning Myers-Perry string. find that rapidly strings are unstable to modes within a bounded range string lengths. The instability occurs because momentum along direction creates potential barrier allows for confinement modes. Yet, five ...

This paper presents a novel method for parametric worst-case execution time (WCET) estimation of loops. The method determines a parametric bound on the iteration space size of loops with both affine and nonaffine loop bounds in an efficient manner using a formulation based on Newton–Gregory interpolating polynomials. Parametric WCET formulae are used to support dynamic scheduling decisions at r...

A form of prime focus corrector for the Gregory system is proposed that provides the sub-arcsecond field of view up to 3 in diameter for the spectral range 0.35 − 0.90 microns. The corrector includes five lenses made of same glass (fused silica is preferable). The distinctive feature of the corrector consists in dissimilar use of the central and edge zones of a front lens disposed in the exit p...
