New NAG Fortran Library routines are described for the solution of systems of nonlinear, first-order, time-dependent partial differential equations in one space dimension, with scope for coupled ordinary differential or algebraic equations. The method-of-lines is used with spatial discretization by either the central-difference Keller box scheme or an(More)
Killer whale (Orcinus orca) audiograms were measured using behavioral responses and auditory evoked potentials (AEPs) from two trained adult females. The mean auditory brainstem response (ABR) audiogram to tones between 1 and 100 kHz was 12 dB (re 1 mu Pa) less sensitive than behavioral audiograms from the same individuals (+/- 8 dB). The ABR and behavioral(More)
SPRINT2D is a set of software tools for solving both steady an unsteady partial differential equations in two-space variables. The software consists of a set of coupled modules for mesh generation, spatial discretization, time integration, nonlinear equations, linear algebra, spatial adaptivity, and visualization. The software uses unstructured triangular(More)
Following the changes to API 671, there is a requirement to reduce temperature around guarded coupling designs. Existing features used in high performance (HP) couplings involve various methods of shrouding and covering prominent rotating parts to ensure a smooth, rounded profile. The extent of the features are raised in line with increased peripheral(More)
