A Mechanistic Analysis of Oxygen Vacancy Driven Conductive Filament Formation in Resistive Random Access Memory Metal/NiO/Metal Structures

Resistive Random Access Memory (RRAM) devices have drawn much interest in the last decade, particularly the concept of a memristor. In this case, the so-called memristance, which provides the relationship between the change in charge (time integral of the current) and flux (time integral of the voltage), is not a constant as in linear elements, but a function of the charge, resulting in a nonlinear circuit element. Applications of such two-terminal electrical devices that provide high densities and low-power operation include, for instance, neuromorphic-type computing elements.

Plain Bearings for Aerospace Applications

Plain bearings are used across a wide range of aerospace applications to help achieve better fuel efficiency, extend maintenance intervals, and lower carbon emissions. These applications include installation in aircraft wing systems (flaps, spoilers, and slats), flight controls, cockpit controls, auxiliary power units, landing gear, door systems, and aircraft interiors (seats, bins, latches, and hinge points). “Our plain bearings even have a footprint on Mars,” said Brett Ricci, GGB Aerospace Strategic Account Manager for North America. “Operating in temperatures between -200°C to +280°C, our plain bearings have served as the primary suspension components in the robotic drilling arm of NASA’s Curiosity Mars Rover since 2012.”

Multi-Domain Command and Control (MDC2)

We are at an inflection point in the evolution of warfare. While technology is rapidly increasing pace, it is also creating an expansion into multiple, parallel domains, and giving enemy forces more options for both disruption and defense. Technology advances are a key factor to successes spanning the spectrum from humanitarian efforts to complex anti-access/area-denial environments. However, technology is only an enabler, and mindsets must change to allow the technology to be a tool for success, and not ignored due to antiquated doctrine, policies, and guidance.

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.

Sandia Computer Modeling Aids Solder Reliability in Nuclear Weapons

Solder isn’t the first thing that comes to mind as essential to a nuclear weapon. But since weapons contain hundreds of thousands of solder joints, each potentially a point of failure, Sandia National Laboratories has developed and refined computer models to predict their performance and reliability.
