Anodized aluminum on LDEF: A current status of measurements on chromic acid anodized aluminum [PDF]
Chromic acid anodize was used as the exterior coating for aluminum surfaces on LDEF to provide passive thermal control. Chromic acid anodized aluminum was also used as test specimens in thermal control coatings experiments. The following is a compilation

Analysis of a single-fold deployable truss beam preloaded by extension of selected face diagonal members [PDF]
A technique for preloading a deployable box truss beam by extension of one face diagonal per bay was studied to determine if it would result in uniform loading of truss joints without causing excessive truss deformations.

Optimization procedure to control the coupling of vibration modes in flexible space structures [PDF]
As spacecraft structural concepts increase in size and flexibility, the vibration frequencies become more closely-spaced. The identification and control of such closely-spaced frequencies present a significant challenge. To validate system identification

Experiences in applying optimization techniques to configurations for the Control of Flexible Structures (COFS) program [PDF]
Optimization procedures are developed to systematically provide closely-spaced vibration frequencies. A general purpose finite-element program for eigenvalue and sensitivity analyses is combined with formal mathematical programming techniques.
