Virtual Testing at the CAD Stage with Simulation Software

June 6, 2007, 2:00 PM
In order to successfully compete in the global marketplace, your product design process needs to be the best in its class, delivering innovative products of the highest quality, at the lowest cost, with the shortest possible design cycle time. Sponsored by Noran Engineering, Inc., NASA Tech Briefs presents a FREE Webinar that examines how progressive engineering departments are accomplishing this by using analysis software at the CAD design stage to virtually test parts and validate structural, thermal, and dynamic performance before they make the first article.

Benefits of PXI Express for Next-Generation Testing

June 20, 2007, 2:00 PM
Learn the capabilities, benefits, and features of PXI Express as a platform for next- generation test systems and instrumentation during this FREE NASA Tech Briefs Webinar sponsored by Geotest, Marvin Test Systems, Inc. Based on PCI Express and CompactPCI technology, PXI Express offers significant performance and bandwidth improvements when compared to current PXI systems, while preserving compatibility with over 1,200 existing PXI products. This flexibility means that PXI Express products will provide engineers with the bandwidth and performance required by tomorrow’s applications, while maintaining compatibility and interoperability with today’s PXI products and applications.

University of Rochester (Rochester, NY) researchers developed a technique, using a laser, white light, and a reflective tube, that in 60 seconds or less measures multiple chemicals in body fluids. The technique tests urine and blood serum for common chemicals important to monitoring and treatment of diabetes and cardio- vascular, kidney, urinary diseases, and lends itself to the development of fast batch testing in hospitals and other clinical settings.

The Rochester team measured 11 chemicals in blood serum, including total protein, cholesterol, LDL and HDL levels, glucose, triglyceride, albumin, bilirubin, blood urea nitrogen, globulin, and CO2. In urine, they identified urea nitrogen and creatinine.

Scientists at the Naval Research Laboratory-Stennis Space Center (NRL-SSC, Washington, DC) have directly derived the air-sea momentum exchange at the ocean interface using observed ocean currents under Hurricane Ivan and determined that it decreases when winds exceed 32 meters per second. Proper evaluation and measurement of the air-sea exchange under extreme winds is of great importance for modeling and forecasting used in hurricane studies, such as in forecasting of storm track and intensity, surges, waves, and currents.

Since coastal regions have become heavily populated, the results should be of widespread interest to the public, oceanographers, atmospheric scientists, numerical modelers, oil and gas concerns, commerce, and government agencies.
