Non-destructive testing (NDT) is a way to detect and evaluate flaws in materials. The simplest and most accurate way of testing materials and components is often to test them to destruction. Destructive testing is used in aerospace to determine the physical properties of materials, components and assemblies. It can reveal …

Magneto resistor is a type of resistor whose resistance changes when an external magnetic field is applied. In other words, the flow of electric current through the magneto resistor changes when an external magnetic field is applied to it. Magnetic field is the region present around a magnetic object …

“Electronics have dramatically changed the way we live, conduct business, communicate, and educate. Visions of the future foretell of ubiquitous computing and sensing. However, the environments in which electronics can reliably operate are limited. In consumer applications, typical operating temperatures range from -40° to 85°C. The “wider” military temperature range …

US Naval Research Laboratory (Naval Research Laboratory, NRL) has allocated $ 45 million for the implementation of a program to study the prospects for the use of genetic engineering for the navy. Part of the program was the development of genetically modified microorganisms capable of detecting the presence of enemy ships, …

It was in the oceans that life first evolved and where complex animals have thrived for over 600 million years. Marine animals survive in environments as diverse as tropical coral reefs, polar ice-capped oceans, and the lightless abyssal depths, says Frank E. Fish from West Chester University and Donna M. …

Police agencies are using facial and object recognition technology for counterterrorism operations. Video footage played a key role in finding the culprits responsible for the November 2015 Paris attacks, with a CCTV video at Brussels airport used to pin down one suspect. But, the sheer volume of video content produced …

Currently, the most widely used technology to detect underwater objects is sound navigation and ranging (SONAR), because acoustic waves can penetrate the water depths to the bottom of the sea. SONAR also suffers from unwanted multipass echoes that are due to reflections from the surrounding terrain. Thus, high-resolution underwater imaging …
