<strong>NASA</strong> Langley Research Center (LaRC) began using the World Wide Web (WWW) in the summer of 1993, becoming<br />
the first <strong>NASA</strong> installation to provide a Center-wide home page. This coincided with a reorganization of LaRC to provide a<br />
more concentrated focus on technology transfer to both aerospace <strong>and</strong> non-aerospace industry. Use of WWW <strong>and</strong> NCSA<br />
Mosaic not only provides automated information dissemination, but also allows for the implementation, evolution <strong>and</strong><br />
integration of many technology transfer <strong>and</strong> technology awareness applications. This paper describes several of these<br />
innovative applications, including the on-line presentation of the entire Technology OPportunities Showcase (TOPS), an<br />
industrial partnering showcase that exists on the Web long after the actual 3-day event ended. The <strong>NASA</strong> <strong>Technical</strong> Report<br />
Server (NTRS) provides uniform access to many logically similar, yet physically distributed <strong>NASA</strong> report servers. WWW is<br />
also the foundation of the Langley Software Server (LSS), an experimental software distribution system which will distribute<br />
LaRC-developed software. In addition to the more formal technology distribution projects, WWW has been successful in<br />
connecting people with technologies <strong>and</strong> people with other people.<br />

Nondestructive Evaluation (NDE) Technology Initiatives Program (NTIP) delivery Order 0029: Advanced Thermosonic<br />
Methods (SONIC IR)<br />

The overall objective of this program was to demonstrate that the Sonic Infrared (IR) inspection technique can be used<br />
reliably to detect a fatigue crack located at the anti-rotation feature on the F100 first stage turbine disk. As the physics of the<br />
mechanical energy to thermal energy conversion for this technique is not well understood at this time, an empirical approach<br />
was used to develop the system parameters that will enable a reproducible inspection technique to be developed. This Delivery<br />
Order covered a literature <strong>and</strong> subject matter expert search, development of a Design of Experiments (DoE) test plan,<br />
production of a test fixture, <strong>and</strong> preliminary interface <strong>and</strong> fixturing materials testing. Fixturing <strong>and</strong> coupling were identified<br />
as key parameters for reliability. Testing was continued on a follow- on program.<br />

A Multidisciplinary Evaluation of Mild Traumatic Brain Injury: Early Predictors of Outcome<br />
Dischinger, Patricia; Apr. 2004; 10 pp.; In English<br />
Contract(s)/Grant(s): DAMD17-03-1-0204<br />
Report No.(s): AD-A425756; No Copyright; Avail: CASI; A02, Hardcopy<br />
The purpose of this study is to identify a cohort of patients with mild Traumatic Brain Injury <strong>and</strong> follow them for 1 year<br />
post-injury to determine injury outcomes <strong>and</strong> identify factors that best predict long-term sequelae. The first year has been<br />
dedicated to finalization of study design <strong>and</strong> testing instruments, <strong>and</strong> logistical planning for this multi-disciplinary effort. Staff<br />
were hired <strong>and</strong> trained, <strong>and</strong> a manual of operations developed to st<strong>and</strong>ardize the protocols for evaluation components. A<br />
