FuelOptimal Trajectories for Aeroassisted Coplanar Orbital Transfer Problem
(1990)
The optimal control problem arising in coplanar, orbital transfer employing aeroassist technology is addressed. The maneuver involves the transfer from high Earth orbit to low Earth orbit via the atmosphere with the object ...
Direct measurement of the anisotropy of the resistivity in the a-b plane of twin-free, single-crystal, superconducting YBa2Cu3O7-
(1990)
We have measured the resistivity tensor in one nearly twin-free crystal and one twin-free crystal of YBa2Cu3O7-. The first crystal was grown with a large twin-free region. We removed the twins in the second crystal by ...
Tensorial volume of turbulence revisited
(1990)
A corrected tensorial turbulent volume transport equation, which is exact for uniform density flows, is derived from the Navier-Stokes equations. For homogeneous turbulence, the new terms appearing in the correct equation ...
