Design of Army aerial vehicles and weapon systems relies on the ability to predict aerodynamic behavior, often aided by advanced computer simulations of the flow of air over the body. High-fidelity simulations assist engineers in maximizing how much load a rotorcraft can lift or how far a missile can fly, but these simulations aren't cheap. A new turbulence model could change that
Researchers from the Korea Maritime and Ocean University show that automation in the shipping industry will lead to an overall increase in shore-based jobs. However, they warn that this will have to be complemented with concerted policy measures to provide the necessary technical training to job seekers and veteran seafarers who will need to adapt to the new technological paradigm.
Although electric vehicles that reduce greenhouse gas emissions attract many drivers, the lack of confidence in charging services deters others. Building a reliable network of charging stations is difficult in part because it's challenging to aggregate data from independent station operators. But now, researchers reporting January 22 in the journal Patterns have developed an AI that can analyze user reviews of these stations, allowing it to accurately identify places where there are insufficient or out-of-service stations.
MIT researchers reveal the kinds of infrastructure improvements that would make the biggest difference in increasing the number of electric cars on the road, a key step toward reducing greenhouse gas emissions from transportation.
To help build aircraft that can better handle violent turbulence, Purdue University researchers developed a new model that allows engineers to incorporate the physics of an entire vortex collision into their design codes.
POSTECH research team led by Professor Junsuk Rho develops nanostructures capable of polarized optical encryption.
While autonomous drones can greatly assist with difficult rescue missions, they require a safe landing procedure. In a new study, scientists from Shibaura Institute of Technology (SIT), Japan, have demonstrated automated drone landing with a simple 2D camera guiding the drone to a symbolized landing pad. The guiding camera can be further improved to include depth-related information, paving the way for novel applications in indoor transportation and inspection.
MIT researchers have proposed a method for growing plant-based materials, like wood and fiber, in a lab. The technology is still in early development but might one day help reduce the environmental footprint of some types of agriculture.
Robots are widely used to build cars, paint airplanes and sew clothing in factories, but the assembly of microscopic components, such as those for biomedical applications, has not yet been automated. Lasers could be the solution. Now, researchers reporting in ACS Applied Materials & Interfaces have used lasers to create miniature robots from bubbles that lift, drop and manipulate small pieces into interconnected structures.
EPFL scientists have developed a metamaterial whose mechanical properties can be reprogrammed on demand and whose internal structure can be modified by applying a magnetic field.
