NIST's seeks a high resolution DIC technology for qualification of complex AM parts. To meet this critical need, X-wave Innovations Inc. proposes to develop a 3-Dimentional Digital Image Correlation (3-D DIC) based NDT system. The proposed effort builds upon the success of XII in developing a variety of NDT technologies (including DIC system) for advanced materials evaluation. The success of the p ...

Historical methods of reliability assessment are less and less effective as device sizes shrink. Already researchers are unable to package the many advanced devices because the act of cutting the wafer and the packaging operation pre-stresses or destroys the devices resulting in unreliable test results. Additionally the increasing cost of fabricating a wafer with advanced integrated circuit techno ...

In response to the increasing demand for better understanding of the manufacturing processes and the machining systems, a new testing standard--ASME B5.54 and a family of new testing instruments have been developed for evaluating the performances of a variety of CNC machining centers. Because of the advancement and versatility of the new instruments, test data are being collected at a much higher ...

We propose to develop an innovative, compact ultrafast high brightness laser source, broadly tunable in the infrared for vibrationally-resolved infrared microscopy and other applications. By passive Kerr lens mode-locking of a novel diode-pumped tunable Cr:LiSAF laser, 100fs pulses will be generated at 100 MHZ repetition rate with an average power of 1W. An optical parametric oscillator (OPO) pump ...

The hydrodynamic characteristics of a vessel are affected in restricted waters by the proximity of nearby moving or moored vessels. Interactions can result in large motions, potential collisions and significant loads on nearby structures, banks, and sediments. In Phase 1, we developed and demonstrated feasibility of a PC-Based numerical code for the prediction of the hydrodynamics of multiple vess ...

THE OBJECTIVE OF THIS PROGRAM IS TO EVALUATE ALTERNATIVE TECHNIQUES FOR PERMANENT IDENTIFICATION OF FISHING GEARS. THE SELECTED TECHNIQUE FOR DURABLE MARKINGS AND LOCATION OF THE TRAWL AND THE LONG-LINE TYPES FOR FISHING GEARS WILL BE DEVELOPED AS A PROTOTYPE AND WILL BE TESTED IN TYPICAL FIELDCONDITIONS. TRAWL AND LONG-LINE FISHING GEARS REPRESENT A SIZABLE INVESTMENT BY THE FISHERMEN AND A RESPE ...

Currently, advanced tools for modeling injection modeling of thermoplastics and predicting formed part dimensional stability and residual stress content use the static bulk modulus of the polymer at the temperatures and pressures associated with the molding process. The short cycle times associated with injection molding, however, could be more accurately modeled if dynamic bulk modulus data were ...

The storage photostimulable phosphor (SPP) technique has been demonstrated to be sensitive to ionization radiation. It is especially suited for detecting alpha particles since the efficiency is practically 100%. In addition to being able to quantify total ionization deposited in a SPP sensor, it also captures the radiation source distribution information in a digital image which can be readily ana ...

Utilizing new hard, etch resistant photoresists derived from epoxy formulations such as SU-8 to serve as the mold for electroless metaldeposition for MEMS electroforming techniques, a fully micro-miniaturized cross capacitor can be realized. A Micro-Electroformed Cross Capacitor (MECC) is built by electroforming high aspect metals atop the substrate. A Phase 1 effort would model MECC performance, ...
