Researchers at the University of Delaware have discovered that fragmented carbon nanotube films can serve as adhesive conductors in lithium-ion batteries.“The problem with the current technology is that the binders impair the electrochemical performance of the battery because of their...

Dr. Vadim Smelyanskiy is a principal scientist for physics-based methods in the Exploration Technology Directorate at NASA Ames Research Center. During his tenure at NASA, he has been the principal investigator on several projects funded by NASA and other government...

Porous silicon nanowires are fabricated by two-step, metal-assisted electroless chemical etching of p-type or n-type silicon wafers. This method, in combination with nanolithography or nanopatterning, can be applied to fabricate porous silicon nanostructures of different...

The Integrated Modular Avionics (IMA) architecture being developed for space applications requires that sensor data be autonomously sampled and transmitted to the system network. This transmission needs to occur on a predetermined, fixed...

A 4-channel digitizer was designed, built, and tested. The very large, complex board enables SweepSAR. The proposed Deformation, Eco-Systems, and Dynamics of Ice Radar (DESDynl-R) Lband SAR instrument employs multiple digital channels to optimize resolution...

NASA has an interest in utilizing the Ka-band frequency allocation. One of the main reasons for migrating to Kaband is the need for higher frequency bandwidth to enable higher data rates. A dual circular polarized wideband antenna for Ka-band communications applications was...

This software addresses the problem of an autonomous vehicle patrolling a region for objects of interest using multiple cameras. The system must identify and track the objects over time and localize their positions in the world. It implements an autonomous perception and...

Electric conduction in polymers is one of the key elements in avoiding catastrophic internal electrostatic discharge in dielectrics during space missions. This software package enables the simulation of carrier mobility for any given site concentration, which is a material design...

The current software has been developed to work on NASA instrument datasets, an upgrade over similar software that only worked on datasets from climate model output. NASA is attempting to reformat satellite data to fit the specific and highly detailed data format and metadata requirements for CMIP5...

A previously created direct numerical simulation (DNS) database of mixing of species under supercritical pressure has been examined and analyzed for the purpose of understanding the modeling requirements in the context of large eddy...

A Fault Detection, Isolation and Recovery (FDIR) system needs some internal concept of how the monitored system operates. This “operating concept” needs mathematical logic to represent the cause and effect relationship between constituent components of the system,...

Available guidance approaches for large numbers (i.e., swarms) of artificial agents are currently very limited. Swarms in nature (e.g., bees, birds, ants) typically contain hundreds to thousands of agents. The problem is how to mimic nature, and develop guidance laws for artificial (manmade)...

In the United States, as many as 7,000 commercial and private aircraft may be in the air simultaneously at any given time and date, and the total number of commercial flights in a given 24-hour period generally exceeds 50,000. To maintain the safety and efficiency of air travel, this innovation...

DAPS was designed to support the DAWN-AIR project participating in the Genesis and Rapid Intensification Processes (GRIP) hurricane campaign. It controls the data acquisition system consisting of a scanner that directs the lidar beam, an inertial navigation system/GPS (INS/GPS) unit for monitoring...

The Debris & ICE Mapping Analysis Tool (DIMAT) system is a Web-based system that supports communication, data integration, data sharing, and problem definition/resolution through use of an integrated presentation framework for ice and debris description and analysis. It provides an integrated...

This lidar data fusion approach is based on associating samples from sparse lidar data with groups of region objects determined by a unique image segmentation approach, HSeg (Hierar - chical Segmentation). This segmentation approach, which was previously developed by...

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) developed K-Glass, a wearable, hands-free head-mounted display (HMD).Unlike virtual reality which replaces the real world with a computer-simulated environment, augmented reality (AR) incorporates digital data...
