IntroductionThe small hole mode swing laser welding has gained increasing recognition due to its ability to bridge gaps, refine microstructures, and enhance the mechanical properties of welds. However, the effects of amplitude, frequency, welding speed, laser beam power, and beam radius on heat flux distribution, melting mode, and three-dimensional temperature field have not been well understood. ...
A muffler is a key component of a car's exhaust system, designed to reduce noise levels and emissions. The vibration of a muffler can have a significant impact on its performance and life. In order to understand the performance and behavior of the muffler, it is necessary to make multi-point vibration measurement. First, it enables engineers to assess the structural integrity and durability of a m...
Schematic diagram of experimental setupNew research has revealed advances in light detection and ranging technology, providing unparalleled sensitivity and accuracy in measuring the distance of distant objects.This study was published in the Physical Review Letters and was the result of a collaboration between Professor Yoon Ho Kim's team at POSTECH in South Korea and the Center for Quantum Scienc...
At a distance of 325 meters, the human eye may only be able to distinguish between a person's head and body, making it difficult to discern any other differences. But a research team including Heriot Watt University in the UK and Massachusetts Institute of Technology in the US has developed a new type of LiDAR scanner that can perform detailed analysis of a person's face from such a distance and c...
Recently, the research team of Chang Lin from the School of Electronics of Peking University and the research team of Li Wangzhe from the Aerospace Information Research Institute of the Chinese Academy of Sciences published a research article entitled "Microcomb synchronized optoelectronics" online in Nature Electronics, realizing the application of photonic chip clocks in information systems for ...
