Recycling technologies for end-of-life lithium ion batteries (LIBs) are not keeping pace with the rapid rise of electric vehicles, storing up a potentially huge waste management problem for the future, according to a new study.
To better understand and predict the outcomes of the steering wheel control dilemma, contrary to many previous studies, in a paper published in IEEE/CAA Journal of Automatica Sinica, Dr. Xiaoxiang Na and Dr. David J. Cole from University of Cambridge argued that using the cooperative game theory to model this type of interaction problems may be more suitable.
Rutgers engineers have embedded high performance electrical circuits inside 3D-printed plastics, which could lead to smaller and versatile drones and better-performing small satellites, biomedical implants and smart structures. They used pulses of high-energy light to fuse tiny silver wires, resulting in circuits that conduct 10 times more electricity than the state of the art, according to a study in the journal Additive Manufacturing.
MIT and Toyota researchers have designed a new model to help autonomous vehicles determine when it's safe to merge into traffic at intersections with obstructed views.
MIT engineers have developed a navigation method that doesn't require mapping an area in advance. Instead, their approach enables a robot to use clues in its environment to plan out a route to its destination, which can be described in general semantic terms, such as 'front door' or 'garage,' rather than as coordinates on a map.
In a study published in the International Journal of Heat and Mass Transfer, Ahmad Najafi, Ph.D., a professor in Drexel's College of Engineering, and his faculty collaborator, Jason Patrick, Ph.D., from North Carolina State University, report on how a computational technique they developed can quickly produce designs for 3D printing carbon-fiber composite materials with an internal vasculature optimized for active-cooling.
Electric vehicle owners may soon be able to pull into a fueling station, plug their car in, go to the restroom, get a cup of coffee and in 10 minutes, drive out with a fully charged battery, according to a team of engineers.
Scientist have developed a lithium ion battery that charges at an elevated temperature but keeps the cell cool during discharge, showing the potential to add 200 miles of driving range to an electric car in 10 minutes. The design is one potential strategy to alleviate concerns that all-electric vehicles lack sufficient cruise range to safely reach a destination without stalling mid-journey. The Pennsylvania State University researchers present the work Oct. 30 in the journal Joule.
To improve the safety of autonomous systems, MIT engineers have developed a system that can sense tiny changes in shadows on the ground to determine if there's a moving object coming around the corner.
The public are more likely to blame accidents involving semi-autonomous cars on driver -- rather than machine -- error, a new study has found.
