Electronics & Software

The Soil Moisture Active-Passive (SMAP) Project Spacecraft Flight Software controls all aspects of command and data handling (CDH) in the SMAP spacecraft. Required capabilities include uplink and command, telemetry and downlink, vehicle attitude control, science instrument control,...

This software partitions a dataset into clusters of data using the Deterministic Annealing algorithm, a more sophisticated clustering technique than usually available in scientific and commercial software. The results provided are deterministic, i.e. unique (within the machine precision tolerance), whereas results...

Eddy is a fundamental research code for advancing spectral methods for complex geometry. The software is intended to enable researchers to collaborate through a common framework that supports three-dimensional simulations on practical problems. Areas of interest include advanced numerical...

Historically, there have been various approaches to problems relating to the detection of small, weak, or hidden objects, substances, or patterns embedded in complex backgrounds. One approach has been to use low-dimensional sensor systems that attempt to detect a clean signature...

This technology provides means of estimating numerical errors in user-specified output functionals, such as lift or drag, for fluid flow simulations. The new method computes an improved estimate of the output (relative to the baseline simulation), an estimate of the...

Minimally invasive and non-invasive therapeutic ultrasound treatments can be used to ablate, necrotize, and/or otherwise damage tissue. High-intensity focused ultrasound (HIFU), for example, is used to thermally or mechanically damage tissue. HIFU thermal...

APPS provides a multi-mission instrument data and metadata (i.e. label) transformation service that interfaces local or remote Mission Data provider’s data processing pipeline/end-products and the PDS (Planetary Data System) data archive to ensure compliance to standards in a schedule/cost-efficient manner (i.e....

There are several different types of wireless radio frequency identification (RFID) tags that are truly zero-power radios. Currently, most unpowered wireless RFID tags only have a range of a few meters. There are longrange, low-powered tags that draw energy either from a battery or some other form of localized power. A...

Sources of wireless power — such as wireless cellphone charging pads — require near-physical contact with the pad, limiting the usefulness of a truly wireless power source. Recent work has extended wireless power to mid-range, which can supply power at inches to feet of separation....

The purpose of the Desktop Status application is to collect processor, memory, and storage usages of a computer running the Microsoft Windows 7 operating system, and record these data with time stamps to files at a user-defined time interval. A graphical user interface (GUI) captures users' inputs and displays them on a plot for...
