A solid median, wide shoulders, minimal hills -- and a high speed limit? Brigham Young University researchers explore freeway features that minimize crash risk.
In motors, generators and similar electric machines, the electrical current that powers them generates magnetic fields that magnetize some of the metallic components. Choosing the right magnetic material is crucial for designing efficient machines, so researchers analyzed the existing system for characterizing soft magnetic materials. To identify a better system, they looked at several factors that can affect the uncertainty inherent in the measurement of magnetic properties. Their results are in this week's AIP Advances.
Soft magnetic core engineering plays a key role in high-efficiency electric motors, but for higher-frequency applications, soft magnetic composites are also promising. Each stage of motor construction affects the material's microstructure, and understanding the details of the microstructure is paramount to reaching higher efficiency for electrical motors. In this week's AIP Advances, researchers created an advanced characterization method to closely examine microscale structural characteristics and changes during manufacturing processes using electron backscatter diffraction.
Researchers from the Camborne School of Mines have identified methods to predict the environmental and social cost of resourcing new deposits of rare earth minerals used in the production of mobile phones, wind turbines and electric vehicles.
Autonomous vehicles should only have to be moderately better than human drivers before being widely used in the United States, an approach that could save thousands of lives annually even before the technology is perfected, according to a new RAND Corporation report.
A marriage between 3-D printer plastic and a versatile hybrid material for detecting and storing gases could lead to inexpensive sensors and fuel cell batteries alike.
Software developed at MIT could tell drivers when their cars need a tuneup, a new air filter, wheel balancing or a tire replacement, just by using a smartphone.
Researchers from Lehigh University and Columbia University shine a light into the black box of deep learning systems with DeepXplore, the first automated white-box testing of such systems. Evaluating DeepXplore on real-world datasets, the researchers were able to expose thousands of unique incorrect corner-case behaviors. They will present their findings at the 2017 biennial ACM Symposium on Operating Systems Principles (SOSP) conference in Shanghai, China, on Oct. 29 in Session I: Bug Hunting.
Researchers at Chalmers University of Technology and the Technical University of Denmark have developed a method that makes it possible to map the individual responses of nanoparticles in different situations and contexts. The results pave the way for better nanomaterials and safer nanotechnology and were recently published in the journal Nature Communications.
We have come a long way from leaky sulfur-acid automobile batteries, but modern lithium batteries still have some down sides. Now a team of Penn State engineers have a different type of lithium sulfur battery that could be more efficient, less expensive and safer.
