Software Helps Restore Fire-Ravaged Habitats

NASA system uses the cloud to give land managers and wildlife experts a post-fire plan.

The Department of the Interior’s Bureau of Land Management (BLM), in addition to coordinating firefighting efforts on federally held lands, is also responsible for the post-fire restoration process that’s meant to limit the harmful fallout.

Advanced Capabilities of PXI-Based Semiconductor Test Systems

The ongoing challenge for today’s semiconductor test engineers is to identify and create new test solutions that can offer significantly lower test costs as well as address the need for configurable, open-architecture, flexible test solutions that can provide comparable features to proprietary ATE platforms. In particular, for test requirements with low to moderate volumes — such as pilot production, verification, and focused production test applications — the need for flexible and cost-effective ATE solutions is particularly acute. For these applications, test engineers historically have relied upon legacy test systems that have a low acquisition cost, but high operating costs or in-house designed rack-and-stack solutions. However, semiconductor test system solutions based on the PXI platform have made significant advancements in functionality and performance over the past three or four years, offering test engineers a viable alternative for both current and future test needs.

Calibration Requirements for Testing Coupling-Decoupling Networks

Coupling-Decoupling Networks (CDNs) are the unglamorous workhorses that get “hitched up” to an impulse generator in order to perform impulse testing on powered equipment. As such, performance and calibration requirements for CDNs have not been specified to the same level of detail as the impulse generator. This is no longer the case with the Third Edition of IEC 61000-4-5, the international standard for surge immunity testing.

NASA Monitoring Technologies Shake Up Earthquake Prediction

The seconds to minutes of advance warning of an earthquake can allow people and systems to take actions to protect life and property from destructive shaking. Earthquake early warning systems use earthquake science and the technology of monitoring systems to alert devices and people when shaking waves generated by an earthquake are expected to arrive at their location. NASA has been one of the agencies at the forefront of earthquake early warning technology for many years, and new monitoring techniques developed by NASA are shaking up the way earthquakes are predicted.

Celebrate Pi Day with NASA Goddard and Discover Pi-Sat

The Innovative Technology Partnerships Office (ITPO) at NASA’s Goddard Space Flight Center (Goddard) in Greenbelt, MD, invites you to celebrate Pi Day on March 14 and discover Pi-Sat. Current technology trends indicate a shift in satellite architectures from large, single satellite missions, to small, distributed spacecraft missions. At the center of this shift is the smallSat/cubesat architecture.

Neural Network Chip Can Perform Powerful Artificial-Intelligence Tasks

In recent years, some of the most exciting advances in artificial intelligence have come courtesy of convolutional neural networks, large virtual networks of simple information-processing units, which are loosely modeled on the anatomy of the human brain. Neural networks are typically implemented using graphics processing units (GPUs), special-purpose graphics chips found in all computing devices with screens. A mobile GPU, of the type found in a cell phone, might have almost 200 cores, or processing units, making it well suited to simulating a network of distributed processors.

Iron Studded BNNTs Could Replace Semiconductors in Wearable Tech

The road to more versatile wearable technology is dotted with iron. Specifically, quantum dots of iron arranged on boron nitride nanotubes (BNNTs). The new material is the subject of a study conducted by Yoke Khin Yap, a professor of physics at Michigan Technological University. Yap says the iron-studded BNNTs are pushing the boundaries of electronics hardware. The transistors modulating electron flow need an upgrade.

Stable "Superoxide" Opens the Door to a New Class of Batteries

While lithium-ion batteries have transformed our everyday lives, researchers are currently trying to find new chemistries that could offer even better energy possibilities. One of these chemistries, lithium-air, could promise greater energy density but has certain drawbacks as well. Thanks to research at the U.S. Department of Energy's (DOE's) Argonne National Laboratory, however, one of those drawbacks may have been overcome.
