Researchers develop algorithm for lensless, miniature cameras

New Delhi: Researchers at Indian Institute of Technology (IIT) Madras and Rice University, U.S., have developed algorithms for lensless, miniature cameras. Such lensless cameras have numerous vision applications in areas such as Augmented Reality (AR)/ Virtual Reality (VR), security, smart wearables and robotics where cost, form-factor, and weight are major constraints. Lensless cameras do not have a lens which, in a conventional camera, acts as a focusing element allowing the sensor to capture a sharp photograph of the scene. Due to the absence of this focusing element, the lensless camera captures a multiplexed or globally blurred measurement of the scene.…

Holding breath may increase risk of getting COVID-19 Infection

New Delhi (India Science Wire): High demand for information on COVID pandemic, its toll on healthcare systems and lives, and the many unanswered questions about a virus that was discovered only in December 2019 have created the breeding ground for myths and fake news. ‘The ability to hold the breath for a minute is a sign of a COVID-free body’, is one such misinformation that went viral during the pandemic. A group of researchers from Indian Institute of Technology Madras (IIT-Madras) has found that, on the contrary, holding breath may increase the chances of getting COVID-19 infection. They modelled the…

Researchers discover a universal phenomenon that may help connect dissimilar fields

New Delhi : Ever observed the flock of pigeons taking off in a jiffy?  Suddenly they take-off helter-skelter but within a flash, they are in a formation. The sudden emergence of spontaneous order is called self-organisation. While the random flight is periodic, the emergence of formation is harmonic. In the self-organisation, individual components organise their collective behaviour to create global order by interactions amongst themselves rather than through external intervention or instruction. Periodic oscillations are prevalent in nature and can have good or bad outcomes. The periodic oscillations in a flute are, for example, soothing, while those of a bridge…
