Delayed detonation in an exploding white dwarf, which propagates from an off-center transition point rather than from a spherical transition shell, is described and simulated. The differences between the results of two-dimensional simulations and the one-dimensional case are presented and discussed. The two-dimensional effects become significant in transition density below 3rho7, where the ener...

he development of a probe for sample tubes of 20-mm outside diameter has increased the sensitivity of natural abundance 3C Fourier transform nuclear magnetic resonance to the point that single-carbon resonances of proteins can be studied. Numerous narrow single-carbon resonances are observed in the aromatic region of the I3C spectrum of native hen egg-white lysozyme. Theoretical and experimenta...

A new method for obtaining digital Fourier holograms, under spatially incoherent white-light illumination and in a single camera shot, is presented. Multiple projections of the 3-D scene are created in the image plane of a microlens array, and a digital camera acquires the entire projections in a single shot. Then, each projection is computer processed to yield a single point in a Fourier holog...

A measurement, modelling and identification system is proposed to qualify a subscriber line with the constraint that only measurements can be conducted at the Central Office. The system uses the one-port scattering parameter as a base measurement of the loop. The time domain version of this scattering parameter will be pre-processed so that the features, which are the start, maximum and end pos...
