Drones Learn Autonomous Flying by Imitating Cars and Bikes

The algorithm DroNet allows drones to fly completely by themselves through the streets of a city and in indoor environments. It produces two outputs for each single input image: a steering angle to keep the drone navigating while avoiding obstacles, and a collision probability to let the drone recognize dangerous situations and promptly react to them.

Quality Control for Additive Manufacturing Parts Using Non-Destructive Testing

Additive Manufacturing (AM) is growing in importance as a fabrication process for the space industry, enabling weight and cost savings through optimized designs for components. The use of AM gives aerospace engineers an alternative to more traditional manufacturing processes, but also retains the challenge of producing parts without defects. These problems can be approached using nondestructive methods such as X-ray Computed Tomography (CT) and Finite Element Modelling (FEM) to inspect geometries and quantify the impact of defects on the mechanical properties of a part, taking into account factors such as internal stress from metal cooling during fabrication.

A Better Understanding of Space — Via Helicopter

An algorithm that helps engineers design better helicopters may help astronomers more precisely envision the formation of planets and galaxies. The new model understands how black holes, planets, and galaxies emerge from the vortex-rich environments of space. Researchers drew inspiration from a mechanical engineering algorithm that shows how air flows past a helicopter’s rotor blades.

Simulation Results Could Help Quiet Jet Noise

Argonne National Laboratory engineers are working to create high-fidelity computer simulations to determine how jet turbulence produces noise. Working on Argonne’s supercomputer Mira, the team is applying computational fluid dynamics to capture the physics of the turbulence that is making the noise.

Air Traffic Management Tool Wins NASA Software of the Year

When planes get caught in traffic, pilots have to keep flying until the backup clears and their runways become available for landing. This means that air traffic controllers must send them on less-direct paths to their final destination, using more fuel in the process.

Eye Tracking Technology Improves Imposter Detection Training

Customs and Border Protection (CBP) screens nearly one million people every day and secures and manages 328 ports of entry all over the country, including in remote areas. Verifying the identity of every single person entering the United States is a vital step in halting human trafficking, drug trafficking, and other smuggling attempts at the border. In addition, security screening prevents criminals and terrorists from entering the country. Imposter detection crosscuts the entire Homeland Security Enterprise, as well as state, local, and tribal law enforcement and even front-line soldiers in our military. All of these frontline operators execute this task as part of their respective missions and they must be able to accurately and efficiently verify identification of individuals to thwart imposters.
