Athanasios Papoulis
Athanasios Papoulis (Greek: Αθανάσιος Παπούλης; 1921 – April 25, 2002) was a Greek-American engineer and applied mathematician.
Life
Papoulis was born in Athens, Greece in 1921 and graduated from National Technical University of Athens. Papoulis was a member of the faculty of the Polytechnic institute of Brooklyn (now Polytechnic Institute of New York University) since 1952.[1]
Studies
Papoulis contributed in the areas of signal processing, communications, and signal and system theory. His classic book Probability, Random Variables, and Stochastic Processes[2] is used as a textbook in many graduate-level probability courses in electrical engineering departments all over the world.
Two classic texts aimed at [engineering] practitioners were [first] published in 1965... [One was] Athanasios Papoulis' Probability, Random Variables, and Stochastic Processes... These books popularized a pedagogy that balanced rigor and intuition.[3]
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
- The Papoulis-Gerchberg algorithm [7][8][9] is an iterative signal restoration algorithm that has found widespread use in signal and image processing.
