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.

Improve Encoder Performance With EtherNet/IP

As industrial automation networks go, EtherNet/IP has more than its share of advantages. It’s fast. It’s flexible. It’s easy to set up. It’s robust. Those advantages, however, come at a price. Users have to invest in infrastructure and devices certified to work with the EtherNet/IP standard.Today, EtherNet/IP is among the most popular industrial networks, and there’s no shortage of compliant devices. Consider motion control applications, for example. There are hundreds of EtherNet/IP actuators, drives, controllers and sensors on the market today.

Python Interface to T-Matrix Scattering Computations (PyTMatrix)

PyTMatrix is a Python interface to a T-matrix numerical scattering computation code originally developed at NASA GISS (Goddard Institute for Space Studies). It integrates into the NumPy/SciPy scientific framework. The software provides streamlined access to numerical T-matrix computations directly from the Python programming language. It retains the original numerical core written in Fortran 77, thus combining the flexibility of Python and the numerical performance of Fortran. It also provides tools for post-processing the output by integrating over various particle size and orientation distributions.

Learning the "Keys" of IoT Security

Network-connected devices provide many opportunities to improve and enrich people’s lives, but the “Internet of Things” has a range of definitions. A consumer’s experience with the “IoT” may be a wearable computer for fitness tracking. A physician may place a connected heartbeat monitor on a patient. An industrial engineer may see the Internet of Things as thousands of sensor points that provide measurements of temperatures, pressures, or valve states.

Tailor-made Computing Solutions Require Diverse I/O Functions

More than ever, users from industry and transportation expect the full system solution, but no longer want to have to worry about the cumbersome configuration and integration of individual hardware components and adapting the software. There is a very simple reason for this: the system supplier of their choice reduces the time to market and is also responsible for the entire system at the same time.
