Common Workflow Service: A Standards-Based Process Management System

As mission operations grow in scale and complexity, there is a prevailing need for automating operational processes to increase efficiency, mitigate risks, and reduce operational costs. The need for automating operational processes has produced a few disparate automation systems within the Advanced Multi Mission Operations System (AMMOS). Without a common solution for process management and automation, each AMMOS subsystem that requires a workflow capability will need to develop its own expertise in the workflow domain as independent systems are developed. This can lead to many incompatible implementations that functionally do similar things. The Common Workflow Service (CWS) attempts to address this issue to avoid independent ad hoc workflow implementations.

NEQAIR v14.x Non-Equilibrium Radiative Transport and Spectra Program

There is a need to calculate the radiative heating rate at the surface of a vehicle entering any atmosphere, (e.g., Earth, Saturn, Titan, Mars, Venus etc). NEQAIR simulates the actual chemical and physical actions and reactions of the gaseous species in high-temperature shock layers. NEQAIR has been NASA’s main radiation code for the past 30 years. It is a line-by-line radiation code that computes spontaneous emission, absorption, and stimulated emission due to transitions between various energy states of chemical species along a line of sight. There have recently been substantial updates to the physics in the code and the computational efficiency in NEQAIR; v14.0 is the first parallelized version that has resulted in calculations speeding up by a factor of approximately 30×.

Systems Engineering Education and Development (SEED) Web Application

This application serves as Web-based management of the Systems Engi - neering Education and Development (SEED) program, and enables the SEED Program Manager to track and manage the applications and assignments. In the past, the handling of the applications and assignments was cumbersome due to a manual process with paper copies of competencies and applicant data. The new system enables the automation of the entire process to streamline determination of both the viability of the applicants and the effectiveness of the program on the participants through the course of their time in the program.

Hammer 1.0

Many software applications have scripting needs including those based on the Goddard Mission Services Evolution Center (GMSEC) framework. In GMSEC, a user may want to automate the actions to take when a sequence of events occurs. Ideally, the scripting solution should allow the use of a familiar programming language and avoid unnecessary constraints. The existing GMSEC Criteria Action Table (CAT) is limited in these respects.

Extended Testability Analysis (ETA) Tool V8.0

This tool provides fast, efficient, and effective diagnostic assessment reports.An assessment of a system’s safety requirements is required early in the design process when cost and time impacts are minimal. These requirements include fault detection, failure isolation, and failure recovery. Systems engineering groups at NASA have been exploring model-based products to better support verification of these safety requirements. One such product involves qualitative failure propagation modeling as a means to achieve early assessment of the system prior to the availability of higher fidelity information. These early development products lack the advanced reporting and analysis capabilities required to address the needs of system designers and domain experts. Therefore, post-processing tools need to be developed to support the interrogation of the model, and the structured reporting required by system engineers.

Will artificial intelligence do more good than bad for humanity?

This week's Question: World-famous physicist Stephen Hawking recently warned that the creation of powerful artificial intelligence will be “either the best, or the worst thing, ever to happen to humanity.” Hawking noted the risks of creating superintelligence with a will of its own, while also mentioning AI's ability to "undo some of the damage done to the natural world" and eradicate disease and poverty. What do you think? Will artificial intelligence do more good than bad for humanity?

Quality Driven: Automotive Display Testing

Instrumentation, information, navigation and entertainment systems have moved to fully graphical, touch-enhanced displays, and customers expect the quality of these displays to be on par with that of their consumer electronics. Makers of in-vehicle displays must keep pace with improvements in display quality, increasing screen sizes, and higher resolutions. Quality inspection of these displays faces a unique set of challenges. They will be viewed in widely varied lighting and must withstand harsh environmental conditions. Detection of subtle flaws that could worsen as a result of these circumstances is critical to ensuring a high quality display throughout the lifespan of the vehicle.
