Accident, infection, surgery, or stroke resulting in brain trauma can leave individuals with significant and pervasive cognitive disabilities. The need to increase fiinctional recovery for these individuals challenges the combined knowledge, skills, and vision across disciplines including neuropsychology, rehabilitation psychology, occupational therapy, speech pathology, and computer science. This paper reports such interdisciplinary research to develop an approach to computer-assisted retraining that can support and encourage patients' own efforts to take charge of their lives again and rebuild their cognitive skills and thereby enhance their vocational and social opportunities. The Adaptable Learning Environment for Rehabilitation Training (ALERT) will track user performance levels, interest, preferences, and progress within an environment that uses Virtual Reality for life-skill simulations and activities to functionally model cognitive task domains. A single standardized assessment method is being designed to collect information about cognitive variables in the context of mediating and support variables. The functional developmental model of recovery upon which ALERT is based will use the ongoing assessment as it updates the patient user model within the intelligent tutoring system to guide the suggestions for treatment at each successive stage.

The Institute for Astronomy has developed and recently installed a high-resolution cross-dispersed echelle spectrograph for use at one of the coude foci of the AEOS 3.7-meter telescope, operated by the Air Force Space Command atop Mt. Haleakala on the island of Maui. The spectrograph features an optical arm for the wavelength range 0.5-1.0 urn and an infrared arm for the range 1.0 - 2.5 microns We review the spectrograph design and present commissioning results obtained with both the visible and infrared arms. Both channels use a white- pupil collimator design to maximize grating efficiency and to limit the size of the camera optics. The visible arm of the spectrograph uses deep-depletion CCDs optimized for operation near 1.0 urn. The infrared detector is a 2048 x 2048 hgCdTe array (HAWAII-2) that has been developed by Rockwell Science Center for this project. Both channels are equipped with slit-viewing cameras for object acquisition and control of a fast guiding tip-tilt mirror located in a pupil image in the spectrograph fore optics., Presented at the 2002 AMOS Technical Conference, Maui, Hawaii 16-20 September 2002.
