Ali N. Akansu is a Turkish American scientist best known for his contributions to the theory and applications of sub-band and wavelet transforms. ==Biography== Akansu received his B.S. degree from the Istanbul Technical University, Turkey, in 1980, his M.S. and PhD degrees from the Polytechnic University, Brooklyn, New York, in 1983 and 1987, respectively, all in Electrical Engineering. Since 1987, he has been with the New Jersey Institute of Technology where he is a Professor of Electrical and Computer Engineering. He was also a Visiting Professor at Courant Institute of Mathematical Sciences of the New York University. He showed and presented academic talks in 1989 that the binomial quadrature mirror filter bank (binomial QMF) is identical to the Daubechies wavelet filter, interpreted and evaluated its performance from a discrete-time signal processing perspective published in April 1990.〔A.N. Akansu, ( An Efficient QMF-Wavelet Structure ) (Binomial-QMF Daubechies Wavelets), Proc. 1st NJIT Symposium on Wavelets, April 1990.〕〔A.N. Akansu, R.A. Haddad and H. Caglar, (Perfect Reconstruction Binomial QMF-Wavelet Transform ), Proc. SPIE Visual Communications and Image Processing, pp. 609–618, Lausanne, Sept. 1990.〕〔A.N. Akansu, R.A. Haddad and H. Caglar, (The Binomial QMF-Wavelet Transform for Multiresolution Signal Decomposition ), IEEE Trans. Signal Processing, pp. 13–19, January 1993.〕 He organized the first wavelets conference in the United States at NJIT in April 1990,〔(1st NJIT Symposium on Wavelets, April 1990 )〕 and in 1992,〔(2nd NJIT Symposium on Wavelets, March 1992 )〕 and co-authored the first wavelet-related engineering book published in the literature entitled ''Multiresolution Signal Decomposition: Transforms, Subbands and Wavelets.''〔Akansu, Ali N.; Haddad, Richard A. (1992), Multiresolution Signal Decomposition: Transforms, Subbands, and Wavelets, Boston, MA: Academic Press, ISBN 978-0-12-047141-6〕 His other contributions include the design of optimal filter banks,〔H.

Avellaneda, ("Portfolio Risk in Multiple Frequencies," ) IEEE Signal Processing Magazine, vol. 28, no. 5, pp. 61-71, Sept. 2011.〕 He also co-authored the book entitled ''A Primer for Financial Engineering: Financial Signal Processing and Electronic Trading.''〔Akansu, Ali N.; Torun, Mustafa U. (2015), A Primer for Financial Engineering: Financial Signal Processing and Electronic Trading, Boston, MA: Academic Press, ISBN 978-0-12-801561-2〕 He was a founding director of the New Jersey Center for Multimedia Research (NJCMR), 1996–2000, and NSF Industry-University Cooperative Research Center (IUCRC) for Digital Video between 1998–2000. He was the vice president for research and development of the IDT Corporation 2000–2001, the founding president and CEO of PixWave, Inc. (an IDT subsidiary) that has built the technology for secure peer-to-peer video distribution over the Internet. He was an academic visitor at David Sarnoff Research Center (Sarnoff Corporation), at IBM's Thomas J. Watson Research Center, at Marconi Electronic Systems, and a Visiting Professor at Courant Institute of Mathematical Sciences of the New York University. He is an IEEE Fellow (since 2008) with the citation ''for contributions to optimal design of transforms and filter banks for communications and multimedia security.''〔http://www.ieee.org/membership_services/membership/fellows/chronology/fellows_2008.html ''IEEE: Fellow Class of 2008''〕 According to the Mathematics Genealogy Project, as of June 2013, Akansu had a total of 19 doctorate students.〔http://genealogy.math.ndsu.nodak.edu/id.php?id=74955 ''Mathematics Genealogy Project : Ali Naci Akansu ''〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ali Akansu」の詳細全文を読む スポンサード リンク
