In this paper, we suggest a seismic signal measurement system that uses a laser interferometer. The heterodyne laser interferometer is used as a seismometer due to its high accuracy and robustness. Seismic data measured by the laser interferometer is used to analyze crucial earthquake characteristics. To measure P-S time more precisely, the short time Fourier transform and instantaneous frequen...

Introduction In New Jersey, Health Monitoring Systems Inc.’s (HMS) EpiCenter collects chief complaint data for syndromic surveillance from 79 of 80 emergency departments (ED). Using keyword algorithms, these visits are classified into syndrome categories for monitoring unusual health events. HAIs are infections that patients acquire while they are receiving treatment for a health condition in a...

This research examines the correlation between seismic activity and variations in ionospheric electron density (Ne) using data from Langmuir probe (LAP) onboard China Seismo-Electromagnetic Satellite (CSES) during nighttime. Statistical analysis of Ms ≥ 6.8 earthquakes that occurred globally August 2018 March 2023 is conducted, as well 6.0 same period, quartile method for fixed revisiting orbit...
