On the battlefield, adversaries no longer rely on predictable attack patterns. Instead, they apply intense pressure from multiple directions to overwhelm a country’s defence systems and exploit any ...
Submissions are now being accepted for the 2026 Eric and Wendy Schmidt Awards for Excellence in Science Communications. The awards honor exceptional science communicators, science journalists, and ...
Abstract: In the realm of smart buildings, the deployment of Internet of Things (IoT) devices, particularly long-range low-power networks (LoRa)-based infrared (IR) sensors, has become increasingly ...
Abstract: This brief introduces a current calibration circuit that is specifically designed for use in a column-parallel Dual-Ramp Single-Slope (DRSS) ADC. This circuit creates two current sources ...
We describe test observations made with a customized 640 x 512 pixel indium gallium arsenide (InGaAs) prototype astronomical camera on the 2.5 m DuPont telescope. This is the first test of InGaAs as a ...
The MQ135 sensor’s versatility allows it to be used for applications such as indoor air quality monitoring, gas leakage detection, and environmental sensing. While its main target gas is carbon ...
This project implements a cost-effective intruder detection system using an Arduino Nano and IR sensor. The system detects unauthorized motion within a 2-30 cm range and triggers immediate audible ...
