A new data release more than doubles the number of gravitational-wave candidate events—and reveals unexpected complexities of merging black holes ...
Abstract: Mechanical fault diagnose of circuit breakers need raw data from multiple sources, including high frequency signals such as current and vibration, as well as low frequency signals such as ...
Abstract: A slow-wave structure (SWS) with a new structure is proposed to improve the output efficiency. The SWS operates at a central frequency of 220 GHz. The manufacture is limited to a certain ...
A DIY square-wave source doesn’t need to be complicated. This compact 1992 design delivers 57 stable, TTL-compatible frequencies from a single crystal-based IC and a handful of support components.
