The Automated Evaluation Software Web application was created using Java Enterprise technologies, which provided capabilities for dynamic report generation and Microsoft output. The Tomcat Application server makes the application robust, fast, and reliable. HTML 4.0 was used to create the user...

A proposed solid-state technology possesses photosensitivity that enables volume hologram recording and a high efficiency of luminescence, enabling stimulated emission. These features were used to record volume Bragg gratings and to demonstrate...

The accuracy of spaceborne sensors measuring reflected solar radiance can be affected by multiple factors. First, instruments with complex optics are sensitive to polarization. The response of such instruments is characterized before launch; however, sensitivity to polarization can change on orbit...

Amethod was developed to model polymorphic heterogeneous multicore processors at a high level of abstraction, and formally verify them. The Bahurupi polymorphic heterogeneous multi-core architecture allows the combination of multiple simple processor cores — which...

The configuration of the reprogrammable field-programmable gate array (FPGA) currently on the market is very susceptible to single event upset when it operates in radiation environments. The current state-of-the-art approach is to refresh the configuration...

To enable NASA’s next-generation missions, there is a critical need for a reconfigurable field programmable gate array (FPGA) that can withstand the wide temperature ranges and radiation of the space environment while consuming minimal power without...

At the time of this reporting, there have been no effective methods of monitoring current in conductors in space without breaking the circuit or making contact with the conductor. In space, reliability rules all designs, and breaking a circuit to insert a sensor to monitor current would reduce...

The Arduino platform was used to develop an interface between two otherwise incompatible commercial devices in order to drive the ATHLETE (All-Terrain Hex-Limbed Extra-Terrestrial Explorer) rover over long distances. The Portable Operations Terminal consists of three distinct parts: a robot-mounted...

Low-density parity-check (LDPC) codes often suffer from an “error floor” in which increasing signal-to-noise ratios do not lead to substantially better error rate performance. Error floors of LDPC codes are often not an inherent problem of the code design, but rather, a...

Based on previously reported procedures for permeabilizing vegetative bacterial cells, and numerous trial-and-error attempts with bacterial endospores, a protocol was developed for effectively permeabilizing bacterial spores, which facilitated the...

Retrieval algorithms like that used by the Orbiting Carbon Observatory (OCO)-2 mission generate massive quantities of data of varying quality and reliability. A computationally efficient, simple method of labeling problematic data points or predicting...

A high-speed data recorder and replay equipment has been developed for reliable high-data-rate recording to disk media. It solves problems with slow or faulty disks, multiple disk insertions, high-altitude operation, reliable performance using COTS hardware,...

In a high-speed signal transmission system that uses transformer coupling, there is a need to provide increased transmitted signal strength without adding active components. This invention uses additional transformers to achieve the needed gain. The prior art uses stronger drivers...
