Image Intensifiers are light amplifiers that can detect and image objects at extremely low light levels. They are useful for applications such as astronomy, high speed imaging, photon counting and fluorescence lifetime measurement. Thus they can produce high contrast images under dark conditions for example in night-time surveillance applications.
Imagine you’re looking at a cartoon that changes a little bit in every frame—like a flipbook. Now let’s say you want to understand what’s happening in that cartoon in a super smart way. Here’s how these three tools help: 1. PCA (Principal Component Analysis) Think of it...
Dr. Koppillil Radhakrishnan visited APSYS lab in January 2023 as a part of a visit to IIT Kharagpur India. Dr. Radhakrishnan is an Indian space scientist who headed the Indian Space Research Organisation between November 2009 and December 2014 as Chairman of Space Commission, Secretary of the Department of Space and Chairman of ISRO.

Flame oscillations under certain flow and equivalence ratio conditions can be controlled using open loop and closed loop controls. Different flame shapes, lift off characteristics can be observed, along with periodic behavious in flame anchoring location. Flame heat release modulations, anchoring, oscillations suppression using acoustic forcing and the effect of resonant burning on NOx emission are important topics of research being addressed.
Schlieren flow visualization is based on the deflection of light by a refractive index gradient. The index gradient is directly related to flow density gradient. Due to this deflection an intensity pattern is created on a screen. Here an initial test of Schlieren using a cangle flame is shown.
