Abdul Jerri

**Abdul Jabbar Hassoon Jerri** () is an Iraqi American mathematician, most recognized for his contributions to *Shannon Sampling Theory, It's Generalizations, Error Analysis, and Historical Reviews*, and in particular his establishment in 2002 of the journal *Sampling Theory in Signal and Image Processing* (STSIP-) with over thirty top international experts as its editors, besides establishing its Sampling Publishing, also his contribution to the general understanding of the Gibbs Phenomenon, where he wrote the first book ever on the subject, published by Springer - Verlag, then he followed it by editing another book on Advances in Gibbs Phenomenon published by Sampling Publishing.

## Ndụ agụmakwụkwọ
Jerri nwetara B.Sc. na physics na nsọpụrụ na Mahadum nke Baghdad (1955) na MS na physics site na Illinois Institute of Technology (1960) na Chicago ebe ọ gara n'ihu na-arụ ọrụ n'ime otu nyocha (1960-63) na Reactor Physics na Radiation na-asọ asọ n'ụzọ Shelter Entrance. O nwetakwara Ph.D. na mgbakọ na mwepụ site na Mahadum Steeti Oregon na 1967 na aha edemede On Extensions of the Generalized Sampling Theorem .*Na Mgbasawanye nke Generalized Sampling Theorem.*

Jerri malitere ọrụ  na ngalaba nke Ngalaba nke mgbakọ na mwepụ na sayensị kọmputa na Mahadum Clarkson na Potsdam, NY (1967), ebe ọ rụrụ ọrụ site na 1967 ruo mgbe ọ lara ezumike nká dị ka prọfesọ emeritus na 2002.

Ọrụ Jerri gụnyere nleta na Mahadum America dị na Cairo, ebe o guzobere mmemme ọmụmụ na mgbakọ na mwepụ na sayensị kọmputa (1972-74). Ọ bụkwa onye nduzi nke Graduate Mathematics Study Program na Mahadum Kuwait (1978-80).

### Onyinye
Jerri bụ Fulbright Scholar nyere onyinye abụọ na Mahadum Sultan Qaboos na Muscat, Oman (1997), na oge nke abụọ, na Mahadim Yarmouk na Irbid, Jọdan (2001). Ọ bụ onye isi nchịkọta akụkọ nke Sampling Theory In Signal And Image Processing (STSIP) - An International Journal.,  na onye nwe Sampling Publishing. N'afọ 1995, Jerri bụ otu n'ime ndị nchọpụta ole na ole nyere aka guzobe SAMPTA (Sampling Theory and Applications) Workshops, nke na-enwe ọmụmụ ihe na mba dị iche iche n'afọ abụọ ọ bụla (Malite na Latvia na 1995, mgbe ahụ Portugal, Norway, US, Austria, Turkey, Greece, France, Singapore, Germany, US, na Estonia na 2017.) 

### Nnyocha
Ọ bụ onye dere ọtụtụ akwụkwọ ndị ọzọ a ma ama: Introduction to Integral Equations with Applications, ya na Students Solution Manual: Sampling Publishing,Introduction to Wavelets ya na Students Soliding Manual (A na Prọfesọ Masaru Kamada dere akwụkwọ ntuziaka nke ikpeazụ); Sampling Publisher. Akwụkwọ ndị ọzọ gụnyere Integral na Discrete Transforms na Applications na Error Analysis: Marcel Dekker, na Linear Difference Equations na Discrate Transform Methods:Sp ringer-Verlag.

O bipụtara ihe karịrị akwụkwọ iri anọ, yana ọtụtụ nkuzi na mpaghara nyocha ya na mba ụwa. Ihe nchọpụta Jerri na-agụnye mpaghara nke Integral na Discrete Transforms, Sampling Expansion na ngwa ya, History and Error Analysis, Gibbs Phenomenon, Transform-Iterative Methods for Nonlinear Problems, na Operational Sum Methods for Difference Equations.

N'ọmụmụ ihe mbụ ya, o webatara isiokwu nke Shannon Sampling Theory na nkuzi awa anọ. N'afọ 1997, a raara usoro ọmụmụ ihe ahụ nye ụbọchị ọmụmụ ihe afọ iri isii na ise. Ka ọ dị ugbu a, ọ na-arụ ọrụ n'ide akwụkwọ nyocha nkuzi na isiokwu "Multidimensional sampling in Signal Processing". Ọ na-enyefe akwụkwọ a maka oge CENTENNIAL nke American Scientist nke narị afọ, nna nke Information Theory, Claude Elwood Shannon.
