We present sharp bounds on the supremum norm of DjSh for j ≥ 2, where D is the differential operator and S the Stein operator for the standard normal distribution. The same method is used to give analogous bounds for the exponential, Poisson and geometric distributions, with D replaced by the forward difference operator in the discrete case. We also discuss(More)
The ascent of a hot spherical body through a fluid with a strongly temperature-dependent viscosity has been studied using an axisymmetric finite element method. Numerical solutions range over Peclet numbers of lo-'-lo3 from constant viscosity up to viscosity variations of 10'. Both rigid and stress-free boundary conditions were applied at the surface of the(More)
The Spectral and Photometric Imaging REceiver (SPIRE), is the Herschel Space Observatory‘s submillimetre camera and spectrometer. It contains a three-band imaging photometer operating at 250, 350 and 500 μm, and an imaging Fourier-transform spectrometer (FTS) which covers simultaneously its whole operating range of 194–671 μm (447–1550 GHz). The SPIRE(More)
Table 2: Relative errors (RE) for two initial conngu-rations using the stress (r = 1) criterion. The numerical results suggest that both X and t 1 ^ X improve on ^ X in practice. In particular, the relative errors of the easily computed optimal dilations of the classical solutions ranged from :2843 to :8317. The relative errors are somewhat larger for the(More)
