The One-Day Workshop on Applied Harmonic Analysis and Sampling Theory, in adjunction with Departmental Colloquium Talk by distinguished speaker Akram Aldroubi, will held at Department of Mathematics, MSB318, on February 2, 2018. The workshop will concentrate on harmonic analysis and sampling theory.

During the workshop, Professor Akram Aldroubi (Vanderbilt University) will discuss a dynamic frame system, which is fundamental for understanding and solving several major problems in engineering and science. Many data sets in image analysis and signal processing are in a high-dimensional space but exhibit a low-dimensional structure. Professor Wenjing Liao (Georgia Tech) will present her works on building efficient representations of these data for the purpose of compression and inference. Stability is a basic concept in sampling theory. Professor Chang Eon Shin (Sogang University, Korea) will provide an overview on stability and norm-controlled inversion of infinite matrices and integral operators. Dynamical sampling is an interdisciplinary field that deals with processing signals that evolve in time. Dr. Sui Tang (John Hopkins University) will discuss dynamic sampling and its connection to sparse signal processing theory and polynomial interpolation theory. Signals with finite rate of innovations appear in many engineering applications such as magnetic resonance spectrum, ultra wide-band communication and electrocardiogram. Professor Qiyu Sun (University of Central Florida) will give a talk on recent advances on phaseless sampling and reconstruction of signals with finite rate of innovations.
