This paper describes the eccentricity, amplitude, phase shift, angular momentum, polarization, radial path, and orbital ...

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

When an object is falling, the two main forces acting on it are weight close weightA force that acts on mass, pulling it down, due to gravity. Weight is a force and forces are measured in newtons (N).

Abstract: Event cameras are bio-inspired sensors that capture intensity changes of pixels individually, and generate asynchronous and independent “events”. Due to the fundamental difference from the ...

We measure the “warmness” of the dark matter, i.e. the comoving root-mean-square thermal velocity v hrms (1) , with nearly 3000 spiral galaxy rotation curves in the ...

Hanging by a thread: Wasp spiders, Argiope bruennichi, are known to incorporate so-called “stabilimenta” into their web structure, but the function of these “extra touches” has remained unknown.

Taking flight: a parasitic roundworm prepares to jump on its host. (Courtesy: Victor M Ortega-Jimenez) Researchers in the US have discovered that a tiny jumping worm uses static electricity to ...

Abstract: In this brief, a global finite-time attitude control algorithm is proposed for flexible spacecraft without angular velocity measurement. First, a global finite-time observer is designed to ...
