Crowd behaviour analytics focuses on behavioural characteristics of groups of people instead of individuals' activities. This work considers human queuing behaviour which is a specific crowd behavior of groups. We design a plug-and-play system solution to the queue detection problem based on Wi-Fi/Bluetooth Low Energy (BLE) received signal strength indicators (RSSIs) captured by multiple signal sniffers...
This study presents a high performance ion-selective field-effect-transistor (ISFET) based pH sensor utilizing commercial touch panel film (TPF) as the sensing material. The coated ITO/SiO2/Nb2O5 multilayer on the TPF is ideal for measuring dissociated hydrogen ions. A high transconductance MOSFET chip composed of 10 parallel FETs is used to convert the effective pH value into the equivalent gate...
