Titan Lake and Shore Sampler

The device is suitable for cryogenic dispensing of fluids, and for cryocoolers.

A lake and shore sampling and sample distribution system was developed for a Titan lake environment (93.7 K, in liquid hydrocarbons). The Titan Lake and Shore Sampler (TLASS) would enable the chemical analysis of hydrocarbon lake...

VLBI Antenna Calibration by GPS

This technique could be adapted to monitor deformations of any large outdoor structure including dams, bridges, and buildings.

The determination of local geodetic parameters for VLBI (very-long-baseline interferometry) antennas is traditionally done by conventional surveying techniques. These techniques...

Predicting Heart Age Using Electrocardiography

Knowledge of a patient’s cardiac age, or “heart age,” could prove useful to both patients and physicians for encouraging lifestyle changes that are potentially beneficial for cardiovascular health. This may be particularly true for patients who exhibit symptoms, but who test negative for...

Integrated Genomic and Proteomic Information Security Protocol

A security protocol requires a cryptanalysis infrastructure not available to most attackers.

The motivation for this research is the fact that, for a variety of reasons, networks and their existing authentication and confidentiality infrastructure are becoming more...

Flight Processor Virtualization for Size, Weight, and Power Reduction

A flight software system that was originally deployed on six separate physical processors is modeled using a single processor.

This work demonstrated the cost-saving and fault-tolerant benefits of virtualization technology by consolidating the flight software from...

Model Predictive Automatic Recovery System

This innovation is designed for aircraft on the verge of a loss-of-control situation.

In commercial aviation, there have been several recent cases of unstabilized approaches that have resulted in crash landings short of the runway. Some of the direst consequences of these incidents may be...

Ionospheric Slant TEC Analysis Using GNSS-Based Estimation (IonoSTAGE)

As signals emitted by global navigation satellite systems (GNSS) propagate toward users on or near the surface of the Earth, they experience delay due to the presence of charged particles in the ionosphere. Currently, ionospheric delay is the largest source of GNSS...
