Shape control of large space structures

A survey has been conducted to determine the types of control strategies which have been proposed for controlling the vibrations in large space structures. From this survey several representative control strategies were singled out for detailed analyses. The application of these strategies to a simplified model of a large space structure has been simulated. These simulations demonstrate the implementation of the control algorithms and provide a basis for a preliminary comparison of their suitability for large space structure control

Compatibility Studies of Various Refractory Materials in Contact with Molten Silicon

The production of low cost, efficient solar cells for terrestrial electric power generation involves the manipulation of molten silicon with a present need for noncontaminating, high temperature refractories to be used as containment vessels, ribbon-production dies, and dip-coated substrates. Studies were conducted on the wetting behavior and chemical/physical interactions between molten silicon and various refractory materials

Lunar Phasing: Program Notes for Graduate Recital

This scholarly paper provides in-depth program notes to accompany the Graduate Recital of Eva Hagan from March 3, 2016. The program included Eric Mandat’s The Moon in My Window; Jonathan Russell’s Night Dance for clarinet and guitar; Meyer Kupferman’s Moonflowers, Baby!; Johannes Brahms’s Sonata Op. 120, No. 2 in E-flat Major for clarinet and piano; and Robert Muczynski’s Fantasy Trio for clarinet, cello, and piano
