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.

Adaptive Refinement Tools for Tetrahedral Unstructured Grids

This software can potentially be used in aerospace, aviation, and automotive applications. NASA’s Langley Research Center engineers have developed a new software package for more facile computational fluid dynamics. The software’s fast user run time, robustness, and efficiency have enabled its extensive use in space shuttle modeling. Adaptive Refinement Tool (ART) permits the computational modeling of flow, including jet or rocket plumes, wakes, and shocks via unstructured tetrahedral grids. Commercially available software packages often struggle to sufficiently and quickly model such complex examples of flow. ART also allows cells to be divided into two, four, or eight cells as compared to traditional software, which allows cell division only in units of eight. This is advantageous as it allows the user to control cell division more succinctly. ART executes commands via colloquial English, and has built-in internal statistical programming that increases its ease of use. ART allows the user the choice of alternate variables such as temperature or pressure at will, which facilitates modeling unusual or unlikely occurrences.

Self-Stabilizing, Byzantine-Fault-Tolerant Clock Synchronization System and Method

Initially developed for wired applications, the technology could also be applied to wireless systems. NASA’s Langley Research Center has developed a portfolio of technologies regarding clock synchronization in distributed systems. Distributed synchronous systems that need to provide globally coordinated operations require each component (node) in the system to be precisely synchronized. Such systems could include electronic components within an aircraft or automobile, or large-scale networks of components that communicate with each other (e.g. multiple aircraft or automobiles). NASA’s technologies provide for very quick synchronization while tolerating various faults. These protocols provide distributed autonomous synchronization (i.e. no master clock signal required) and do not rely on any assumptions regarding the initial state of the system or internal status of the nodes.
