2024-10-10 15:33:23
Alaska geologist Mark Myers hopes that underground reserves of hydrogen could fuel a new state energy industry.
Engineers develop a way to streamline solar cell testing, accelerating a process that can be slow and costly
2024-10-10 15:33:23
The process of testing new solar cell technologies has traditionally been slow and costly, requiring multiple steps. Led by a fifth-year Ph.D. student, a Johns Hopkins team has developed a machine learning method that promises to dramatically speed up this process, paving the way for more efficient and affordable renewable energy solutions.
New composite material uses ultra-thin rubber-like layers to combine stiffness with high damping capacity
2024-10-10 15:33:23
A compressor hums, an air conditioning system rattles, a railway carriage chassis clatters, sending reverberations through its passengers. Vibrations are not only annoying but can also be harmful. Over the long term, they can destroy materials and machines and shorten their service lives. What's more, the noise generated by vibrations is harmful to human health and well-being.
New technology converts wastewater to sustainable aviation fuel with potential 70% reduction in emissions
2024-10-10 15:33:23
Made from renewable materials like biomass and agricultural waste, sustainable aviation fuel has enormous potential to decarbonize the aviation industry. But widespread adoption has yet to take off.
A severe solar storm is headed toward Earth this week, forecasters say
2024-10-10 09:36:26
Space weather forecasters say a severe solar storm heading to Earth could stress power grids even more as the U.S. deals with major back-to-back hurricanes.
The status and trend of audible sound-based tool wear monitoring
2024-10-10 09:35:59
In general, tool failure contributes about 7% to the down time of machine centers. And more severely, tool failure will reduce the machining quality of parts, and even damage the machine. Therefore, Tool wear condition monitoring (TWCM) is an important part of intelligent manufacturing, and has been a research hotspot since 1968.

Overcoming 'catastrophic forgetting': Algorithm inspired by brain allows neural networks to retain knowledge
2024-10-10 05:53:56
Neural networks have a remarkable ability to learn specific tasks, such as identifying handwritten digits. However, these models often experience "catastrophic forgetting" when taught additional tasks: They can successfully learn the new assignments, but "forget" how to complete the original. For many artificial neural networks, like those that guide self-driving cars, learning additional tasks thus requires being fully reprogrammed.
An electronic tongue that detects subtle differences in liquids also provides a view into how AI makes decisions
