Regional Hydrologic Extremes Assessment System (RHEAS) Software

Drought is Africa’s principal type of natural disaster and is at the core of serious threats to the livelihoods of millions of people and the natural resources on which they depend. The economies of many African countries are based on agricultural activities that are controlled...

Briefs: Software

The mechanical properties of sheet metal materials are directional. Their deformation behavior and their strength differ significantly depending on the viewing direction; for example, in the direction of rolling, or...

Briefs: Communications

Hundreds of small robots can work in a team to create biology-inspired shapes without an underlying master plan, purely based on local communication and movement. To achieve this, the biological...

Articles: Mechanical & Fluid Systems

With the computational power and software available today, numerical simulation is a real option to quickly get answers to complicated technical, scientific, and engineering questions. Not only has the hardware...

Application Briefs: Test & Measurement

Attitude detection is a crucial element in aircraft and spacecraft navigation. The motion of an aircraft consists of a translational component (motion of its center of mass with respect to...

Briefs: Transportation

Marine-grade stainless steel is valued for its performance under corrosive environments, and for its high ductility — the ability to bend without breaking under stress. But conventional...

Facility Focus: Information Technology

Established in 1943, Los Alamos National Laboratory (LANL) in New Mexico was site Y of the Manhattan Project for a single purpose: to design and build an atomic bomb, which took just 27 months. The Los Alamos...

Geodesolver for the Geodesic Equation

NASA has a need to determine the distribution of dark matter around planets like Earth. Doing so necessitates the ability to repeatedly solve the geodesic equation in simulations of weakly interacting particles streaming through bodies described by a Schwarzschild metric. Geodesolver numerically solves the...

Briefs: Aerospace

NASA has developed a novel method to render visible the density changes in air that cause a refractive index change by an airborne vehicle. These density changes include shock waves, vortices,...

Technique Measures Temperature of 2D Materials at the Atomic Level

Newly developed two-dimensional (2D) materials such as graphene — which consists of a single layer of carbon atoms — have the potential to replace traditional microprocessing chips based on silicon, which have reached the limit of how small they can get. But engineers have...

Briefs: Photonics/Optics

High-speed images of a common laser-based metal 3D printing process, coupled with newly updated computer models, have revealed the mechanisms behind material redistribution, a phenomenon that...

Sensor Detects Nuclear Weapon Solvent

A new sensor picks up signatures of tributyl phosphate, a solvent used to enrich uranium, including for use in a nuclear weapon. Enzymes can detect tributyl phosphate signatures, but the lifespan of the enzymes is too short to make them practical for sensors.

Briefs: Manufacturing & Prototyping

Using 3D printers, researchers have created a metamaterial from cubic building blocks that responds to compression forces by a rotation. Usually, this can only be...

Briefs: Aerospace

NASA’s Langley Research Center has developed aircraft flap tip modifications that reduce noise produced during approach and landing. The modifications are rigid open lattice (honeycomblike) and fin structures...
