This engineering exam, which is a gateway to some of the premium engineering colleges such as IITs, NITs and more, cover ...

Abstract: Terahertz (THz) circular synthetic aperture radar (CSAR) demands higher precision in motion compensation (MOCO), posing significant challenges. To address this issue, this article proposes a ...

Abstract: Autofocus serves to mitigate the residual motion error (RME) in the airborne synthetic aperture radar (SAR). However, the 2D frequency dependent RME remains ...

The racket from some 70,000 pickleball courts across the United States has generated bitter fights. If we understand the ...

Sony’s Bravia 8 II was voted the top TV of 2025 by a panel of experts — including our own Nilay Patel. The dazzling QD-OLED ...

Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts ...

Researchers have confirmed the true ferrielectric state in a single-phase material, (MV)[SbBr5]. This new polar order ...

A network of optical cavities could be used to detect gravitational waves (GWs) in an unexplored range of frequencies, according to researchers in the UK. Using technology already within reach, the ...

Speed is a measure of how fast an object is moving. Calculate speed using the speed equation - speed = distance divided by time. The speed equation can be rearranged to find distance travelled and ...

Pressure is a measure of how concentrated a force is. The amount of pressure exerted on an object depends on the force applied and the surface area it is spread over. Force diagrams and resultant ...
