'''Vijay Prasad Dimri''' is an Indian [[geophysical]] scientist, known for his contributions in opening up a new research area in [[Earth sciences]] by establishing a parallelism between [[deconvolution]] and [[Inversion (geology)|inversion]], the two vital geophysical signal processing tools deployed in minerals and [[oil and gas exploration]].<ref name="GERMI">{{cite web | url=http://www.germi.org/former_directors.html | title=GERMI | publisher=GERMI | date=2014 | access-date=8 November 2014}}</ref><ref name="Deconvolution and Inverse Theory">{{cite book | url=http://www.elsevier.com/books/deconvolution-and-inverse-theory/dimri/978-0-444-89493-9 | title=Deconvolution and Inverse Theory | publisher=Elsevier | author=V.

Dimri's career started at the [[National Geophysical Research Institute]] (NGRI) in 1970<ref name="GERMI" /> where he rose in ranks to reach the position of the director in 2001,<ref name="INSA" /> a position he held till 2010.<ref name="Indian Express">{{cite web | url=http://www.newindianexpress.com/states/andhra_pradesh/article226613.ece?service=print | title=NGRI director Dimri honoured with Padma Sri | newspaper=Indian Express | date=26 January 2010 | access-date=8 November 2014}}</ref><ref name="ICSU">{{cite web | url=http://www.icsu.org/about-icsu/structure/committees/scientific-planning-review/?icsudocid=committee-from-oct | title=ICSU | publisher=ICSU | date=2014 | access-date=8 November 2014}}</ref> He is also an honorary Professor at [[Andhra University]] and holds the position of adjunct professor at [[Indian Institute of Technology, Kharagpur]] and the [[Osmania University]], Hyderabad.<ref name="GERMI" /><ref name="INSA" />

In 2010, retiring from the NGRI, Dimri joined Gujarat Energy Research and Management Institute (GERMI), Gandhinagar and is the incumbent director there.<ref name="Asia Oceania" /> He is a national correspondent of The [[International Association for the Physical Sciences of the Oceans]]<ref name="IAPSO">{{cite web | url=http://iapso.iugg.org/information/user-profile6/userprofile/dimri.html | title=IAPSO | publisher=IAPSO | date=2014 | access-date=8 November 2014}}</ref> and sits on the Scientific Planning and Review committee of the [[International Council for Science]] (ICSU).<ref name="ICSU" />

==Legacy==
One of the first scientific achievements of Dimri related to the [[Mineral exploration|mineral]] and [[oil and gas exploration]]s. He is reported to have developed a redesigned [[Wiener filter]], a common equipment used seismic deconvolution procedure, for application in magnetic and inversion of gravity measurements for mapping susceptibility and subsurface density.<ref name="GERMI" /><ref name="NGRI">{{cite web | url=http://www.ngri.org.in/pdir.html | title=NGRI | publisher=NGRI | date=2014 | access-date=8 November 2014}}</ref> Thus, he was successful in establishing a parallelism ''between [[deconvolution]] and [[Inversion (geology)|inversion]]'', two vital signal processing tools.<ref name="GERMI" /> He demonstrated experimentally that single channel and multi channel time varying filters are equivalent and algorithms for stationary data could be applied to stationary geophysical data processing as well.<ref name="NGRI" /> He also propounded the usage of [[maximum entropy method]] to nonstationary and complex geophysical data analysis.<ref name="GERMI" /> His book, ''Deconvolution and Inverse Theory'', published by Elsevier in 1992, contained these findings and was reported to be accepted by other scientists such as Professor M. Koch, who called it a ''didactical masterpiece''<ref name="INSA" /> and is considered as a reference book on the subject.<ref name="GERMI" /><ref name="NGRI" />

Dimitri is credited with the first quantification of gravity interpretation. He also hypothesized a covariance gravity model for the [[Bay of Bengal]].<ref name="NGRI" /> He argued that the earthquakes in Koyna and Warna areas were triggered by the self organized fractal seismicity of the [[Koyna dam|neighbourhood reservoir]]. He has also contributed to the geophysical data analysis, interpretation of earthquakes and exploration of hydrocarbons and groundwater.<ref name="NGRI" /> His current projects relate to the development of a ''Tsunami Wave Propagation'' model in the aftermath of the [[Tsunami of 2004]] that originated from the sea earthquake of [[Sumatra]] region<ref name="NGRI" /> and setting up of a pilot project for enhanced oil recovery from India oil wells, a Norwegian collaborative project.<ref name="GERMI" /><ref name="INSA" />

During his tenure at the [[National Geophysical Research Institute]], Dimri formulated two programs, ''Gas+Hydrates'' and ''Legal Continental Shelf'' and organised a ''fluoride free water'' project in [[Nalgonda]], Andhra Pradesh, for assessment, management and exploration of groundwater in hardrock terrains.<ref name="INSA" /> During this time, NGRI emerged as a premier institute of geophysics, with NISCAIR, New Delhi rating it as the no. 1 in geophysical outputs among Indian institutes in 2006 and SCOPUS 2007 placing NGRI among the top 1 per cent in the world in terms of citations.<ref name="ICSU" /> It was during his period, NGRI commercialised its first patent.<ref name="INSA" />

Vijay Prasad Dimri is credited with over 125 research papers published in peer reviewed journals and six books, two authored and four edited works,<ref name="Fractal Behaviour of the Earth System">{{cite book | title=Fractal Behaviour of the Earth System | publisher=Springer | author=Vijay Prasad Dimri | year=2010 | pages=208 | isbn=978-3642065859}}</ref> brought out by publishers such as [[Elsevier (magazine)|Elsevier]], [[Springer Publishing|Springer]] and [[August Aimé Balkema|Balkema]]<ref name="GERMI" /><ref name="INSA" /><ref name="Indian Express" /><ref name="ICSU" /><ref name="NGRI" /><ref name="Barnes and Noble">{{cite web | url=http://www.barnesandnoble.com/c/vijay-prasad-dimri | title=Barnes and Noble | publisher=Barnes and Noble | date=2014 | access-date=8 November 2014}}</ref><ref name="Abe Books">{{cite web | url=http://www.abebooks.co.uk/book-search/author/dimri-vijay/sortby/3/page-1/ | title=List of Books on Abe Books | publisher=Abe Books | date=2014 | access-date=8 November 2014}}</ref> He also holds three patents<ref name="INSA" /> of which one is accepted by the US.<ref name="GERMI" /><ref name="Patent Buddy">{{cite web | url=http://www.patentbuddy.com/Inventor/Dimri-Vijay-Prasad/7312375 | title=Patent Buddy | publisher=Patent Buddy | date=2014 | access-date=8 November 2014}}</ref><ref name="Patent">{{cite web | url=http://patents.justia.com/inventor/vijay-prasad-dimri | title=Generation of three dimensional fractal subsurface structure | publisher=Justia Patents | date=14 October 2004 | access-date=8 November 2014 | author=Ravi Prakash Srivastava, Vijay Prasad Dimri}}</ref>
