We tested popular wideband O₂ controllers against lab-grade equipment to see how accurate their lambda readings really are under real engine conditions.

Abstract: Wireless sensor networks (WSNs) play a vital role in modern applications such as healthcare, smart cities, and environmental monitoring. However, their potential is often limited by energy ...

Solar background and multiple scattering degrade the profiling depth and ocean-color parameter retrieval of ocean LiDAR. Our anti-interference circularly polarized LiDAR effectively suppresses these ...

Abstract: A cooperative integrity monitoring (CIM) algorithm is proposed in this work. Under the CIM architecture, the algorithm can fully exploit the global navigation satellite system (GNSS) data ...
