Prony's reformulation
Prony analysis (Prony's method) was developed by Gaspard Riche de Prony in 1795. However, practical use of the method awaited the digital computer. Similar to the Fourier transform, Prony's method extracts valuable information from a uniformly sampled signal and builds a series of damped complex exponentials or damped sinusoids. This allows for the estimation of frequency… WebA SHORT-TIME PRONY METHOD FOR THE DETECTION OF TRANSIENTS Annie Cuyt1, Wen-shin Lee1, and Min-nan Tsai1,2 ... the reformulation still holds. 4 SIMULATION RESULTS …

Some materials may naturally form discontinuities such as cracks as a result of deformation. As an aid to the modeling of such materials, a new framework for the basic equations of continuum mechanics, called the ‘peridynamic’ formulation, is proposed.
