Engine Air-Brakes

Airplanes, one of humanity's greatest inventions, evoke feelings of awe and amazement for most people, unless you live uncomfortably close to a major airport, in which case the feeling may become annoyance and irritation. Constant aircraft noise causes sleepless nights, stress and other health issues, reducing quality of life.

Rugged Server and Display System

General Micro Systems
Rancho Cucamonga, CA
(800) 307-4863

General Micro Systems Inc. (GMS) recently announced that the U.S. Army will exclusively deploy powerful rugged server and display systems from GMS to run the multifunction video display (MVD) software within Type II medium mine protection vehicles (MMPV). The GMS system comprises four components – two chassis and two displays. It also includes an enterprise-class, ultra-rugged, secure server with an intelligent 12-port 1/10 Gigabit Ethernet switch, a router, mass-media storage, CITV/DVR, video-over-IP, and two ultra-thin, rugged smart-panel PCs. When coupled with a video encoder, the system is a complete full motion video and control system with storage.

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.

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.
