AMMOS Common Access Manager (CAM)

The Common Access Manager (CAM) software was developed to control access to functions and data for mission control, telemetry, tracking, instrument data, and other ground data system capabilities. The CAM software is used by Advanced Multi-Mission Operations System (AMMOS) and Deep Space Network (DSN) subsystems, and is available for use in any NASA-funded mission.

Automating Optimization and Design Tasks Across Disciplines

A multidisciplinary design analysis and optimization (MDAO) solution leverages existing analysis codes to streamline optimization tasks early in the design process.

When tackling modern engineering projects, designers must consider not only engineering parameters, but also such key factors as cost, safety, and environmental impact. To exploit the interactions of these various elements, designers must consider them simultaneously. Unfortunately, doing so significantly increases project complexity.

Aviation Environmental Design Tool (AEDT)

The Federal Aviation Administration's Aviation Environmental Design Tool (AEDT) is a software system that dynamically models aircraft performance in space and time to estimate fuel consumption, emissions, noise, and air quality assessments. Full-flight gate-to-gate analyses are possible for study sizes ranging from a single flight at an airport, to scenarios at the regional, national, and global levels.

Intelligent Software Enables Design of Greener, More Efficient Construction Vehicles

University of Warwick (UK) engineers are optimizing the fuel economy of next-generation offhighway vehicles by introducing new intelligent power systems for improved engine operation. This could lead to significant fuel savings and fewer carbon emissions for the industry. The team is analyzing a current fleet of construction vehicles to better understand the opportunities for emissions reduction and intelligent control.

Shift: Self-Healing Independent File Transfer

Shift replaces traditional sequential transfers, which are highly vulnerable to failures at every point along the path between the client and remote file systems.

In high-end computing environments, remote file transfers of very large data sets to and from computational resources are commonplace, as users typically are widely distributed across different organizations and must transfer in data to be processed, and transfer out results for further analysis. Local transfers of this same data across file systems are frequently performed by administrators to optimize resource utilization when new file systems come online or storage becomes imbalanced between existing file systems. In both cases, files must traverse many components on their journey from source to destination, where there are numerous opportunities for performance optimization as well as failure. A number of tools exist for providing reliable and/or high-performance file transfer capabilities, but most do not support local transfers, require specific security models and/or transport applications, are difficult for individual users to deploy, and/or are not fully optimized for highest performance.

Designing Stronger Concrete

Plasticity at small scales boosts concrete's utility as the world's most-used material by letting it constantly adjust to stress, decades or centuries after hardening. To find out why, Rice University researchers performed an atom-level computer analysis of tobermorite, a naturally occurring crystalline analog to the calcium-silicate-hydrate (C-S-H) that makes up cement, which in turn holds concrete together. By understanding the internal structure of tobermorite, they hope to make concrete stronger, tougher, and better able to deform without cracking under stress.

Designing Materials with Reprogrammable Shape and Function

Researchers from Harvard University's John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Wyss Institute of Biologically Inspired Engineering have developed a general framework for designing reconfigurable metamaterials — materials whose function is determined by structure, not composition.

Software Improves Medication Adherence for Heart Stent Patients

MyIDEA (My Interventional Drug-Eluting Stent Education App) software was developed by researchers at the University of Illinois at Chicago (UIC) who study data-simplification to improve clinical outcomes. The tablet computer application helps heart patients with drug-eluting stents take their medications correctly.

Launch Trajectory Acquisition System (LTAS) Simulator

The objective of the LTAS Simulator application is to transmit one or more streams of simulated LTAS data frames in User Datagram Protocol (UDP) packets to the network. Each LTAS data frame is filled with simulated data values, with each data field determined using several methods: 1) constant value from the user’s input via a graphical user interface (GUI), 2) internal generated counter from a start value, 3) internally generated random value using uniform probability that is set by the user, and 4) internally generated modified value using uniform probability that is set by the user.
