Apparatus for making curved reflectors Patent
Forming mold for polishing and machining curved solar magnesium reflector with reinforcing rib
Process sequence produces strong, lightweight reflectors of excellent quality
Large compound curved surfaces for collecting and concentrating radiation are fabricated by the use of several common machining and forming processes. Lightweight sectors are assembled into large reflectors. With this concept of fabrication, integrally stiffened reflective sectors up to 25 square feet in area have been produced

Charged branes interactions via Kalb-Ramond field
Because of its versatility, the 2-form field has been employed to describe a
multitude of scenarios that range from high energy to condensed matter physics.
Pushing forward in this endeavor we study the interaction energy, intermediated
by this kind of field, between branes in a variety of configurations. Also, the
so-called Cremmer-Scherk-Kalb-Ramond model, which consists of the
electromagnetic field coupled to the Kalb-Ramond gauge potential, is
considered. It turns out that these models exhibit a much richer class of
sources than usually thought, able to intermediate novel forms of interactions
in different scenarios.Comment: 12 latex pages, more general result
Distribution of Eigenvalues of Ensembles of Asymmetrically Diluted Hopfield Matrices
Using Grassmann variables and an analogy with two dimensional electrostatics,
we obtain the average eigenvalue distribution of ensembles of asymmetrically diluted Hopfield matrices in the limit . We found that in the limit of strong dilution the distribution is
uniform in a circle in the complex plane.Comment: 9 pages, latex, 4 figure
