USC researchers find sea stars' shape plays an important role in their ability to withstand dynamic water forces and remain attached to surfaces. Understanding such shape shifting could help design underwater robots that can similarly adapt to extreme hydrodynamic environments.
A new study by computer scientists found that when individuals in an experiment about autonomous vehicles were informed that their peers were more likely to sacrifice their own safety to program their to vehicle hit a wall rather than hit pedestrians who were at risk, the percentage of individuals willing to sacrifice their own safety increased by approximately two-thirds.
Programmed magnetic nanobeads paired with an off-the-shelf cellphone and plug-in diagnostic tool can diagnose COVID-19 in 55 minutes or less.
The University of Toronto Engineering research team used city and survey data to map Toronto's entire cycling network - including the new routes - and found that additional bike infrastructure increased low-stress road access to jobs and food stores by between 10 and 20 per cent, while boosting access to parks by an average of 6.3 per cent.
All high-level AVs rely heavily on sensors, and in the paper, 'Realistic LiDAR with Noise Model for Real-Tim Testing of Automated Vehicles in a Virtual Environment', published in the IEEE Sensors Journal, researchers from the Intelligent Vehicles Group at WMG, University of Warwick have specifically simulated and evaluated the performance of LiDAR sensors in rain.
Responding to artificial intelligence's exploding demands on computer networks, Princeton University researchers in recent years have radically increased the speed and slashed the energy use of specialized AI systems. Now, the researchers have moved their innovation closer to widespread use by creating co-designed hardware and software that will allow designers to blend these new types of systems into their applications.
Experts analysing crime and car accident data in Mexico City found a surprisingly high level of synchronicity between the two on a weekly cycle, suggesting that applying more resources to prevent road accidents would improve crime rates by enabling more efficient policing.
Boreyko's team is working toward removing large sheets of ice by increasing the amount of charge that comes near the frost.
Autonomous underwater vehicles have become versatile tools for exploring the seas. But they can be disruptive to the environment or have trouble traveling through confined spaces. Purdue University researchers are studying an alternative: highly maneuverable, low-cost underwater gliders that operate silently.
In civil engineering, flexural beams are used to control the effect of vibrations that can cause cracks to appear in surfaces (concrete slabs) and beams. This is particularly important in buildings that require high tensile strength and where the use of machinery can cause a lot of vibrations that can disturb structural integrity.
