A Tribute to Jean Morlet
نویسنده
چکیده
There are no doubts. We owe wavelet analysis to Jean Morlet. How did Morlet discover wavelets? Here is the story. During the late seventies Morlet was working as a geophysicist for the Elf-Aquitaine company. He had to process the backscattered seismic signals which carry the information related to the geological layers. These seismic signals present transient patterns. Processing such signals with conventional tools such as windowed Fourier analysis or Gabor wavelets often creates numerical artifacts. Morlet elaborated wavelet analysis to overcome this problem. Quoting the geophysicist Pierre Goupillaud,

Two-photon absorption and polymerization ability of intramolecular energy transfer based photoinitiating systems.
We design a new photoinitiating system where the two-photon absorption of a 2,7 bisaminofluorene moiety leads to the photoactivation of a camphorquinone subunit through a Förster-type intramolecular energy transfer: the application to a two-photon polymerization reaction is demonstrated.

There are such great names in language studies as Noam Chomsky, Lev S. Vygotsky, Howard Gardener and Michael Halliday who are widely accredited with having introduced new concepts in linguistics and neighboring disciplines and to whom we remain deeply indebted. In this article which has been written on the occasion of Professor Henry Widdowson's visit in April 2018 to Azarbaijan Shahid Madani U...
