Jean Morlet
Jean Morlet (; 13 January 1931 – 27 April 2007) was a French geophysicist who pioneered work in the field of wavelet analysis around the year 1975. He invented the term ''wavelet'' to describe the functions he was using. In 1981, Morlet worked with Alex Grossmann to develop what is now known as the Wavelet transform. Biography Morlet graduated from the École Polytechnique in 1952 and was research engineer at Elf Aquitaine when he invented wavelets to solve signal processing problems for oil prospecting. Awards He was awarded in 1997 with the Reginald Fessenden Award. He was awarded in 2001 with the first prize Prix Chéreau Lavet, from the Académie des Technologies.

France
France (), officially the French Republic ( ), is a country primarily located in Western Europe. It also comprises of overseas regions and territories in the Americas and the Atlantic, Pacific and Indian Oceans. Its metropolitan area extends from the Rhine to the Atlantic Ocean and from the Mediterranean Sea to the English Channel and the North Sea; overseas territories include French Guiana in South America, Saint Pierre and Miquelon in the North Atlantic, the French West Indies, and many islands in Oceania and the Indian Ocean.

Elf Aquitaine
Elf Aquitaine is a French brand of oils and other motor products (such as brake fluids) for automobiles and trucks. Elf is a former petroleum company which merged with TotalFina to form "TotalFinaElf". The new company changed its name to Total in 2003 and TotalEnergies in 2021. Elf has been as a major brand of TotalEnergies since then. History Founding and mergers (1965-1993) Elf Aquitaine's heritage is rooted among three French oil companies: Régie Autonome des Pétroles (RAP), Société Nationale des Pétroles d'Aquitaine (SNPA), and Bureau de Recherches de Pétroles (BRP). These companies were formed to exploit the discovery of a gas field in Saint-Marcet in the Aquitaine region of south-western France. In December 1965, RAP and BRP were merged to form Entreprise de Recherches et d'Activités Pétrolières (ERAP). ERAP had SNPA, Union Générale des Pétroles (UGP), and Union Industrielle des Pétroles (UIP) as subsidiaries. The resulting company achieved vertical integra ...

Centre International De Rencontres Mathématiques
The Centre International de Rencontres Mathématiques (CIRM) is a mathematics research institute associated with the Centre National de la Recherche Scientifique (CNRS) and the Société Mathématique de France (SMF). It is located in Luminy, Marseille, France, and is affiliated with Aix-Marseille University. CIRM hosts weekly workshops on diverse topics where mathematicians and scientists from all over the world come to do collaborative research. Modeled as a "villa Medici of mathematics", it receives around 3,500 visitors per year. History In 1954, a report from the CNRS discussed potential sites for a meeting place to hold international seminars and workshops in mathematics similar to the Mathematisches Forschunginstitut Oberwolfach. The Luminy estate, formerly owned by the prominent Fabre shipping family, was chosen in 1976. The estate was handed over to the SMF in 1979. The center opened in 1981 and the first workshop was held in 1982. Scientific programs CIRM supports a var ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Society Of Exploration Geophysicists
The Society of Exploration Geophysicists (SEG) is a learned society dedicated to promoting the science and education of exploration geophysics in particular and geophysics in general. The Society fosters the expert and ethical practice of geophysics in the exploration and development of natural resources, in characterizing the near-surface, and in mitigating earth hazards. SEG has more than 14,000 members working in more than 114 countries. SEG was founded in 1930 in Houston, Texas but its business office has been headquartered in Tulsa, Oklahoma since the mid-1940s. While most SEG members are involved in exploration for petroleum, SEG members also are involved in application of geophysics methods to mineral exploration as well as environmental and engineering problems, archaeology, and other scientific endeavors. SEG publishes ''The Leading Edge'' (''TLE''), a monthly professional magazine, ''Geophysics'', a peer-reviewed archival publication, and ''Interpretation'', a peer-revie ...

Wavelet Transform
In mathematics, a wavelet series is a representation of a square-integrable ( real- or complex-valued) function by a certain orthonormal series generated by a wavelet. This article provides a formal, mathematical definition of an orthonormal wavelet and of the integral wavelet transform. Definition A function \psi \,\in\, L^2(\mathbb) is called an orthonormal wavelet if it can be used to define a Hilbert basis, that is a complete orthonormal system, for the Hilbert space L^2\left(\mathbb\right) of square integrable functions. The Hilbert basis is constructed as the family of functions \ by means of dyadic translations and dilations of \psi\,, :\psi_(x) = 2^\frac \psi\left(2^jx - k\right)\, for integers j,\, k \,\in\, \mathbb. If under the standard inner product on L^2\left(\mathbb\right), :\langle f, g\rangle = \int_^\infty f(x)\overlinedx this family is orthonormal, it is an orthonormal system: :\begin \langle\psi_,\psi_\rangle &= \int_^\infty \psi_(x)\overli ...

Geophysics
Geophysics () is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, and the use of quantitative methods for their analysis. The term ''geophysics'' sometimes refers only to solid earth applications: Earth's shape; its gravitational and magnetic fields; its internal structure and composition; its dynamics and their surface expression in plate tectonics, the generation of magmas, volcanism and rock formation. However, modern geophysics organizations and pure scientists use a broader definition that includes the water cycle including snow and ice; fluid dynamics of the oceans and the atmosphere; electricity and magnetism in the ionosphere and magnetosphere and solar-terrestrial physics; and analogous problems associated with the Moon and other planets.

Alex Grossmann
Alexander Grossmann (5 August 1930 – 12 February 2019) was a French- American physicist of Croatian origin. He travelled to the United States in 1955, working in the physics departments of the Institute for Advanced Study (IAS), Princeton, Brandeis University, and the Courant Institute, NYU, then again at the IAS until 1963. After one year at the Institut des Hautes Études Scientifiques (IHES) in Bures-sur-Yvette, France, he joined the "Centre de Physique Théorique de Marseille" (the CPT) as it was being created in 1966, at the request of Daniel Kastler. He then becomes research supervisor at the CNRS. At the Université de la Méditerranée Aix-Marseille II The University of the Mediterranean Aix-Marseille II was a French university in the Academy of Aix and Marseille. Historically, it was part of the University of Aix-Marseille based across the communes of Aix-en-Provence and Marseille in southe ... in Luminy campus he did pioneering work on wavelet analysis with ...
