WebDec 19, 2006 · In this letter, a new threshold algorithm based on wavelet analysis is applied to smooth noise for a nonlinear time series. By detailing the signals decomposed onto different scales, we smooth the details by using the updated thresholds to different characters of a noisy nonlinear signal. This method is an improvement of Donoho's … WebRead this exciting story from Domus India March 2024. Held in New Delhi in 2024, the second edition of the Cyrus Jhabvala Memorial Lecture, delivered by architect Rahul Mehrotra, focussed on why it is necessary to go beyond polarised binaries during the making of architectures — soft thresholds and spaces — that are visually and physically porous, …
