On October 19, 2020, the Mw7.6 Sand Point earthquake struck south of the Shumagin Islands in Alaska.Moment tensors indicate the Bicycle Trainers earthquake was primarily strike-slip, yet the event produced an enigmatic tsunami that was larger and more widespread than expected for an earthquake of that magnitude and mechanism.Using a suite of hydrod
Various forms of integral representations of the electromagnetic field are considered.It is shown that the use of analytically developed integral representations of the electromagnetic field instead of the vector TROUSERS JEANS potential method makes it possible to significantly simplify the formulation of the internal and external electrodynamic p
The voice service is one of the mainstream services under the telecommunications network.The FIBRE CLINIX COLOR BOOSTER mainstream voice service quality evaluation method in the industry is to compare the voice and audio of the transceiver and calculate the POLQA MOS, which is the standard benchmark for voice quality analysis.For telecom operators,
An external modulation laser module assembly (EMLMA) is proposed to suppress nonlinear errors in an interferometry system and improve its measurement performance.The EMLMA employs both phase modulation with radio frequency signal and a specific modulation amplitude switching mode, enabling the suppression of noise introduced by spurious reflections
