In a new study, researchers from the Indian Institute of Technology, Kharagpur and the Institute of Pulmocare and Research, Kolkata, have developed a new, efficient method to detect asthma—by listening to the sound made by the lungs of the patients. Their findings were published in the journal Computer Methods and Programs in Biomedicine.
Researchers from IISST used simple polymethyl methacrylate (PMMA) to partially correct a turbulent laser beam and restore its statistical order.
