Prof. Mohsen Razzaghi
Department of Mathematics and Statistics, Mississippi State University, USA
Prof. Mohsen Razzaghi's area of research
centers on orthogonal functions, optimal control, wavelets,
fractional calculus and their applications in science and
engineering. His work is about numerical approximation using
polynomial series and orthogonal functions, in particular, in
the area of "hybrid functions" by combining piecewise and
continuous basis functions. He was the first to use Legendre
wavelets for approximating solutions to problems in dynamical
systems with jump discontinuities.
He has over 160 refereed journal publications in mathematics, mathematical physics, and engineering. Most of his refereed papers are published in prestigious international journals. He was invited to write an article titled, "Walsh Functions" for inclusion in the Encyclopedia of Electrical and Electronics Engineering, published by John Wiley & Sons in 1999. According to Google Scholar, one of his papers coauthored with a Ph.D. student was cited over 475 times.
Speech Title: Environmental Management and Mathematical Modeling
Abstract: After several decades of rapid technological
advancement and economic growth, levels of pollution and
environmental degradation are rising all over the world.
Research and development in emissions reduction and an efficient
mathematical modeling offer the best promise to assist the
development of an effective means to halt the accelerating trend
of environmental deterioration. Applications of mathematical
research methodologies such as optimization techniques and
control theory are crucial to the development of environmental
management. Orthogonal functions often used to represent an
arbitrary time function have been used to solve various problems
in optimization techniques. Orthogonal functions may be widely
classified into three families. The first includes sets of
piecewise constant basis functions (PCBFs) (e.g., block-pulse,
Walsh, etc.), the second consists of sets of orthogonal
polynomials (e.g., Chebyshev, Legendre, etc.), and the third are
widely used sets of sine-cosine functions in the Fourier series.
While orthogonal polynomials and sine-cosine functions together
form a class of continuous basis functions, PCBFs have
discontinuities or jumps. For problems in environmental
modeling, images often have properties that vary continuously in
some regions and discontinuously in others. Thus, in order to
properly approximate these spatially varying properties, it is
necessary to use approximating functions that can accurately
model both continuous and discontinuous phenomena. Therefore,
neither continuous basis functions nor PCBFs alone can
accurately model these spatially varying properties.
In this talk, we present a new approach to the problems in environmental modeling. Our approach is based upon hybrid functions, which are combinations of piecewise and continuous basis functions. Numerical examples are included to demonstrate the applicability and the accuracy of the proposed method.
