Шаблон:Short description Шаблон:Infobox scientist
Athanasios Papoulis[1] (Шаблон:Lang-el; 1921 – April 25, 2002) was a Greek-American engineer and applied mathematician.
Life
Papoulis was born in modern day Turkey in 1921, and his family was moved to Athens, Greece in 1922 as a consequence of the Population exchange between Greece and Turkey. He earned his undergraduate degree from National Technical University of Athens. In 1945, he stowed away on a boat to escape the impending Greek Civil War and settled in the United States. He studied under the supervision of John Robert Kline at the University of Pennsylvania and earned his Ph.D. in Mathematics in 1950. His dissertation was titled On the Strong Differentiation of the Indefinite Integral.[2]
He married Caryl Engwall in New York, New York in 1953, and had five children: Irene, Helen, James, Ann, and Mary. In 1952, after teaching briefly at Union College, he became a faculty member at the Polytechnic Institute of Brooklyn (now Polytechnic Institute of New York University), where he earned the distinction of University Professor.[3]
Studies
Papoulis contributed in the areas of signal processing, communications, and signal and system theory. His classic book Probability, Random Variables, and Stochastic Processes[4] is used as a textbook in many graduate-level probability courses in electrical engineering departments all over the world.
Шаблон:Quotation By staying away from complete mathematical rigor while emphasizing the physical and engineering interpretations of probability, Papoulis's book gained wide popularity.
Theory
Athanasios Papoulis specialized in engineering mathematics, his work covers probability, statistics, and estimation in the application of these fields to modern engineering problems. Papoulis also taught and developed subjects such as stochastic simulation, mean square estimation, likelihood tests, maximum entropy methods, Monte Carlo method, spectral representations and estimation, sampling theory, bispectrum and system identification, cyclostationary processes, deterministic signals in noise (part of deterministic systems and dynamical system studies), wave optics and the Wiener and Kalman filters.
Contributions
- Papoulis's generalization of the sampling theorem[5] unified many variations of the Nyquist–Shannon sampling theorem into one theorem.[6][7]
- The Papoulis–Gerchberg algorithm[8][9][10] is an iterative signal restoration algorithm that has found widespread use in signal and image processing.[11][12]
- "Papoulis's eloquent proof"[13] of the conventional sampling theorem[14] requires only two equations.
