SUMMARY:Applied Math Talk: Cluster analysis on covariance stationary ergodic processes and locally asymptotically self-similar processes (Nan Rao\, CGU)
DESCRIPTION:We study the problems of clustering covariance stationary ergodic processes and locally asymptotically self-similar stochastic processes\, when the true number of clusters is priorly known. A new covariance-based dissimilarity measure is introduced\, from which efficient consistent clustering algorithms are obtained. As examples of application\, clustering  fractional Brownian motions and clustering multifractional Brownian motions are respectively performed to illustrate the asymptotic consistency of the proposed algorithms.

SUMMARY:Indiana Pols Forced to Eat Humble Pi: The Curious History of an Irrational Number (Edray Goins\, Pomona)
DESCRIPTION:In 1897\, Indiana physician Edwin J. Goodwin believed he had discovered a way to square the circle\, and proposed a bill to Indiana Representative Taylor I. Record which would secure Indiana’s the claim to fame for his discovery.  About the time the debate about the bill concluded\, Purdue University professor Clarence A. Waldo serendipitously came across the claimed discovery\, and pointed out its mathematical impossibility to the lawmakers.  It had only be shown just 15 years before\, by the German mathematician Ferdinand von Lindemann\, that it was impossible to square the circle because $\pi$ is an irrational number.  This fodder became ignominiously known as the “Indiana Pi Bill” as Goodwin’s result would force $\pi = 3.2$.\n\nIn this talk\, we review this humorous history of the irrationality of $\pi$.  We introduce a method to compute its digits\, present Lindemann’s proof of its irrationality (following a simplification by Miklos Laczkovich)\, discuss the relationship with the Hermite-Lindemann-Weierstrass theorem\, and explain how Edwin J. Goodwin came to his erroneous conclusion in the first place.

SUMMARY:Some Unexpected Mathematics Arising From Research at NIST ( Hunt\, NIST)
DESCRIPTION:A lot of the mathematics done at NIST supports the research on and measurement of advanced materials and technology. In this rather applied context. surprising mathematics makes an appearance. We present a few examples.
