Instability of stellar structures intermediate between white dwarfs and neutron stars shown by stellar models, discussing pulsar signals periodicities
Power spectrum analysis of photometric observations of white dwarf stars for measuring variability of stellar luminosity
Error bounds for orthogonal signals in additive white Gaussian noise channels for class of generalized decision strategies permitting variable-size list decoding
Test program simulating solar wind outside magnetosphere to evaluate high melting point high density ceramic oxides as white thermal control coating pigments
Optimal deterministic inputs derived for estimating dynamic control system parameters from white observation noise
Pulsating very dense white dwarfs models noting general relativity
Cooling time estimation for white dwarf stars with ion component undergoing condensation, based on plasma thermodynamic properties
High luminosity white dwarfs possible evolution from planetary nebulae, discussing plasma neutrino processes
The well-known technique of detecting binary pulses in white noise and unknown dc drift by means of a high-pass filter followed by a bit-by-bit detector is not theoretically optimum. The optimum procedure is shown to require a rank-ordering operation on the received data.
