The overall goal of the proposed project is to develop an integrated and intelligent framework for multi-fidelity data-driven modeling, statistical model validation, and adaptive model refinement. The salient aspects of the proposed solution are: (1) use of multi-fidelity modeling to infuse partial or prior knowledge of the systems (e.g., low-fidelity data or simplified physics models) into the da ...

Miniaturized base metal electrodes (BME) multilayer ceramic capacitors (MLCC) are of great interest for future missile applications as designers are striving to achieve smaller, lighter, cheaper, faster and better electronic assemblies without sacrificing long-term performance. Unfortunately, screening, reliability and qualifications criteria are either not available or not standardized. In the ...

Attollo proposes to develop an integrated sensor/classifier Focal Plane Array (FPA) where the neural network is implemented in a floating gate memory crossbar network. This device can be trained to identify low signal threats in high clutter environments, and hand that low-bandwidth information to the system for tracking.

Gold contamination in Circuit Card Assembly (CCA) solder joints leads to brittle intermetallic compounds (IMCs), which is one of the major factors in solder joint failure. The conventional rule of thumb considers 3 wt% of gold (Au) as a safety threshold, which is not always reliable due to varieties of package platforms, solder types, reflux settings, operational and environmental conditions, etc. ...

There is a growing need to study the effects of radiation in space and during high-altitude flights on electronic systems. The ever increasing need for ground based testing has outstripped the supply of available accelerator facilities at which to perform this testing. In response to this problem, RadiaBeam, Michigan State University, and Particle Accelerator Corporation are developing a compact, ...

Our proposed second order uncertainty (SOU) product is a decision making software solution that addresses the problem of providing accurate and precisely defined decision courses of action (COAs) of complex, time-constrained problems in a fraction of the time required by alternative methods striving to achieve the same level of precision. Complex decision situations can deal with large volume of ...

The DoD has identified a need to develop radiation hardened electronic components capable of surviving and operating through exposure to radiation environments encountered in space. To protect these electronic components, systems typically employ a combination of methods for radiation protection. International FemtoScience (FemtoSci) proposes a practical solution to produce Inherently Radiation Ha ...

The ISSAC Team propose a novel method to encapsulate legacy models and simulations that allows these components to take advantage of modern, multi-core, multi-processor hardware suites. Encapsulating these legacy codes provides 3 primary advantages to deal with complex systems and systems of systems (Air Force, Navy, Department of Homeland Security (DHS), Federal Emergency Management Agency (FEMA) ...

Space Micro will develop the core of the decision support system, assemble the models and material properties and demonstrate the utility of the program in materials selection on a subset of failures related to a specific test-bed, which will be the attachment of quad-flat no-leads (QFN) and ball grid array (BGA) devices to printed wiring boards using different solders, underfills, QFN or BGA geom ...

Circuit card assembly (CCA) reliability is dependent on solder joints, which join components to printed circuit boards (PCBs). Board users strive to mitigate risks associated with gold-embrittled solder joints. Enig Associates, Inc. (ENIG), in collaboration with Sandia National Laboratories, proposes to develop a risk-forecasting tool for quantifying the risks associated with gold-embrittled sold ...
