TIE: The Imagery Exchange for the NASA Global Imagery Browse Services (GIBS) Project

The NASA Earth Observing System Data and Information System (EOSDIS) is a data-centric system designed for processing and archiving from NASA’s Earth Observation missions and their distribution, as well as provision of specialized services to users. The major components of EOSDIS are 12 Distributed Active Archive Centers (DAACs), 14 Science Investigator-led Processing Systems (SIPSs), and the EOS Clearing House (ECHO). The Global Imagery Browse Services (GIBS) is the value-added image archive and access service for NASA Earth Science data products. It is the high-resolution global imagery solution for NASA. As the central imagery hub, GIBS is in need of an automated, scalable imagery capturing and generation solution.

Space Communications and Navigation (SCaN) Game Phase III

The Space Communications and Navigation (SCaN) program is responsible for providing communications and navigation services to spaceflight missions located throughout the solar system. Astronauts, mission controllers, and scientists depend upon the reliable transmission of information between Earth and spacecraft in low Earth orbit (LEO) or deep space.

Adverse Condition and Critical Event Prediction Toolbox (ACCEPT)

One of the main features is the relaxation of the technical conditions required for robust early detection of the onset of adverse events.Many natural or complex engineered systems rely upon critical functions or processes that can be measured with the aid of various sensors or other novel devices. As a result, sensor and measurement data can be used to learn a parametric or non-parametric model of the behavior for a given process or metric. For such processes or metrics, it may be critical to avoid or be forewarned of impending level crossings that may characterize entry into extreme or potentially catastrophic operating regimes. Under certain circumstances, the metric to be monitored may represent the residual, or difference between an actual value and a predicted value generated by an independent regression method, rather than a physical process having a physically interpretable meaning.

MATLAB Webification Science Client

The Matlab Webification Science Client consists of several functions that access remote w10n-sci repositories to retrieve data. It supports user sessions to authenticate and authorize access to restricted repositories. In command line mode, it can list the contents of a w10n-sci node, change to other nodes, and retrieve data in chunks or as entire files. Command line mode facilitates batch processing of w10n-sci data by embedding these functions in custom MATLAB scripts.

Lunar Thin Section Particle Identification and Analysis Algorithm

Particle shape is a very important property in many fields of research, and with many practical, diverse, and commercially important applications including pharmaceuticals, civil engineering, metallurgy, health, and food processing. Many of the methods used to evaluate the shapes of solid particles employ a plane section through the particles. This mode may be termed Plane of Section. Plane of Section abstracts three-dimensional (3D) objects to two dimensions (2D).

Libibvpp

Libibvpp provides a C++ wrapper API to the libibverbs library. Libibverbs is the OpenIB library that provides the Verbs API for programming Infiniband hardware. It is written in C and provides a C API. Because the API is in C, it is up to the library user to do explicit resource management for the objects created through the API.

Analytical Methodology to Predict the Radiometric Emissivity of a Parabolic Mesh Reflector

The demands for high-sensitivity and high-resolution radiometry have recently led the science community to examine the use of large deployable mesh reflectors, which have heretofore only been used in telecommunications applications.
