SHINE, which stands for Spacecraft Health Inference Engine, is a multi-mission reusable knowledge base software tool for the monitoring, analysis and diagnosis
of spacecraft and ground systems through forward and backward inference. SHINE advances the state-of-the art in artificial intelligence by enabling solutions to a broad class of problems. |

XML-Based SHINE Knowledge Base Interchange Language
new!

|
Date added: 10/01/2008 |

The problem with decision trees is that they can be expensive to execute because it involves evaluating each non-leaf node and based upon its truth, to either progress deeper into the structure or examine an alternative. This
requires many machine cycles. The solution was to develop a standard language to represent a decision tree and use the industry standard XML language as the universal exchange vehicle. Then implement a transformational compiler that maps the XML representation into a set of forward chaining inference rules. |

Date added: 09/02/2008 |
In this podcast John Dunec, Branch Manager of COMSOL, Inc., discusses how the breakthrough of multiphysics modeling techniques is making waves in the electronics industry. Applications cover everything from modeling p-n junctions in semiconductors and joule heating in circuits to forced convective cooling of circuit boards.
Based on the April 9, 2008 webcast sponsored by COMSOL, this free podcast introduces you to applying multiphysics modeling techniques to electronic analysis and guides you through several examples including electro-thermal stress analysis in a surface coil, simulating a high-frequency RF inductor, and thermal effects on cross-talk between bond wires. |

Parallel Computing for the Computed- Tomography Imaging Spectrometer
|
|
Date added: 09/01/2008 |
|
This software computes the tomographic reconstruction of spatial-spectral data from raw detector images of the Computed-Tomography Imaging Spectrometer (CTIS), which enables transient-level, multi-spectral imaging by capturing spatial and spectral information in a single snapshot. The CTIS can be used for surveying planetary landscapes through spectral imaging. |

Multichannel Networked Phasemeter Readout and Analysis
|
|
Date added: 09/01/2008 |
|
Netmeter software reads a data stream from up to 250 networked phasemeters, synchronizes the data, saves the reduced data to disk (after applying a low-pass filter), and provides a Web server interface for remote control. Unlike older phasemeter software that requires a special, real-time operating system, this program can run on any general-purpose computer. |
