Using low-cost sensors to build a seismic network for earthquake early warning (EEW) and to generate shakemaps is a cost-effective way in the field of seismology.National Taiwan University (NTU) network employing 748 P-Alert sensors based on micro-electro-mechanical systems (MEMS) technology is operational for almost the last 10 years.This instrume
Introduction: Novel coronavirus (COVID-19) pandemic is the worst health emergency the world has seen in the last 100 years.It has adversely affected human life both directly and indirectly.The pandemic has led various countries to opt for lockdown to control the outbreak.India had also enforced lockdown in the country from 25 March 2020 in various
We report InP/InGaAs modified unitraveling-copyright balanced photodiodes (PDs).The back-illuminated PDs were flip-chip bonded on diamond submounts for enhanced heat sinking.The device demonstrated a 3-dB bandwidth of 8 GHz BUCKWHEAT RICE CAKES and a 30-dB common-mode rejection ratio at frequencies of <; 10 GHz.High saturation current of > 32
Radar Absorbing Materials (RAM) are compounds that absorb incidental electromagnetic radiation in tuned frequencies and dissipate it as heat.Its preparation involves the adequate processing of polymeric matrices filled with compounds that act as radar absorbing centers in the microwave range.This work shows the electromagnetic evaluation of Other r
