SUMMARY:CCMA Luncheon Seminar - Data driven methods for dynamical systems:
Extracting spatiotemporal patterns from high-dimensional time series
DESCRIPTION:Seminar: CCMA Luncheon Seminar\nTitle: Data driven methods for
dynamical systems: Extracting spatiotemporal patterns from high-dimensiona
l time series\nSpeaker: Dimitrios Giannakis\, New York University (Host: J
Harlim)\nAbstract: Large-scale datasets generated by dynamical systems ar
ise in many applications in science and engineering. A research topic of c
urrent interest in this area involves using data collected through observa
tional networks or output by numerical models to extract the salient modes
of variability from high-dimensional data\, and create low-order models t
o forecast these modes. In this talk we discuss applied mathematics techni
ques to address this topic blending ideas from machine learning\, harmonic
analysis\, and delay-coordinate embeddings of dynamical systems. We illus
trate these techniques with applications to climate atmosphere ocean scien
ce.

SUMMARY:CCMA Luncheon Seminar - Adaptive Learning and Optimization for Mach
ine Intelligence
DESCRIPTION:Seminar: CCMA Luncheon Seminar\nTitle: Adaptive Learning and Op
timization for Machine Intelligence\nSpeaker: Haibo He\, University of Rho
de Island\nAbstract: With the recent development of brain research and mod
ern technologies\, scientists and engineers will hopefully find efficient
ways to develop brain-\nlike intelligent systems that are highly robust\,
adaptive\, scalable\, and \nfault tolerant to uncertain and unstructured e
nvironments. Yet\, developing such truly intelligent systems requires sign
ificant research on both fundamental understanding of brain intelligence a
s well as complex engineering design. This talk aims to present the recen
t research developments in computational intelligence to advance the machi
ne intelligence research and explore their wide applications across differ
ent critical engineering domains. Specifically\, this talk covers numerous
aspects of the foundations and architectures of adaptive learning and con
trol. The key objective is to achieve cognitive‐alike optimization and p
rediction capability through learning. An essential component of this talk
is a recent development of a new adaptive dynamic programing (ADP) archit
ecture for improved learning and optimization capability over time. This a
rchitecture integrates a hierarchical goal generator network to provide th
e system a more informative and detailed goal representation to guide its
decision-making. Various real-world applications including smart grid\, ro
botics\, cyber‐physical systems\, and big data analysis\, will be presen
ted to demonstrate the broader and far‐reaching applications of our rese
arch.

SUMMARY:CCMA Luncheon Seminar - Aerodynamic Design Optimization by A Contin
uous Adjoint Method
DESCRIPTION:Seminar: CCMA Luncheon Seminar\nTitle: Aerodynamic Design Optim
ization by A Continuous Adjoint Method\nSpeaker: Feng Liu\, University of
California\, Irvine (Host: J Xu)\nAbstract Link: http://fliu.eng.uci.edu\n
Abstract: I will present our latest research progress on the development o
f a continuous adjoint method to perform aerodynamic design optimization o
f wings and turbomachinery blade rows. This method requires only about twi
ce the computational effort of flow calculation to obtain the complete gra
dient information at each operating condition\, regardless of the number o
f design parameters. Therefore\, it is orders-of-magnitude more efficient
than a conventional finite-difference method for obtaining the gradient in
formation in a optimization procedure when the design parameters are in th
e hundreds and more. Examples of single and multiple-point design of trans
onic wings and turbomachinery blade rows will be presented.

SUMMARY:CCMA Luncheon Seminar - Block Preconditioning for Multi-physics: Fr
om Jacobi to Schur Complements
DESCRIPTION:Seminar: CCMA Luncheon Seminar\nTitle: Block Preconditioning fo
r Multi-physics: From Jacobi to Schur Complements\nSpeaker: Eric Cyr\, San
dia National Laboratory (Host: J Xu)\nAbstract: Developing scalable solver
s for fully-coupled multi-physics is challenging. One approach is to use a
dvanced multigrid algorithms to achieve scalability on these problems. How
ever\, this approach can suffer from stability issues\, in particular the
coarse grid operators used in AMG can become ill-conditioned. An alternati
ve to fully-coupled multigrid is to use a block decomposition of the linea
r system. This segregates the linear system into physical fields. For inst
ance separating Navier-Stokes into velocity and pressure components leads
to a 2x2 Jacobian operator. These approaches are appealing because segrega
ted operators are more amenable to multigrid\, yet achieving good parallel
scalability for the coupled system is still possible. The difficulty with
these methods is efficiently and effectively handling the coupling betwee
n the different physics. In this talk I will overview a number of block pr
econditioners focusing on exploiting the structure of the operators. Furth
ermore\, I will present a few techniques for approximating Schur-complemen
t operators. To make this concrete\, applications in fluid dynamics and ma
gnetohydrodynamics will be discussed.

SUMMARY:CCMA Luncheon Seminar - Finite time singularities of inhomogeneous
elasticity
DESCRIPTION:Seminar: CCMA Luncheon Seminar\nTitle: Finite time singularitie
s of inhomogeneous elasticity\nSpeaker: Tao Huang\, Penn State University
\nAbstract: We study the formation of finite time singularities in the for
m of super norm blowup for a spatially hyperbolic system modeling inhomoge
neous elasticity\, which is related to the variational wave equations. The
system possesses a unique $C^1$ solution before the emergence of vacuum i
n finite time\, for given initial data that are smooth enough\, bounded an
d uniformly away from vacuum. At the occurrence of blowup\, the density be
comes zero\, while the momentum stays finite\, however the velocity and th
e density of the energy are both infinite.

SUMMARY:CCMA Luncheon Seminar - Solitary waves in lattices: an introduction
DESCRIPTION:Seminar: CCMA Luncheon Seminar\nTitle: Solitary waves in lattic
es: an introduction\nSpeaker: Anna Vainchtein\, University of Pittsburgh (
Host: X Li)\nAbstract: The interplay between discreteness and nonlinearity
in many physical systems leads to the formation of solitary waves. For ex
ample\, such waves were experimentally observed in granular materials\, el
ectrical transmission lines and optical fibers. Much of the interest in th
ese nonlinear waves was triggered by the pioneering study by Fermi\, Pasta
and Ulam (1955). The subsequent work of Zabusky and Kruskal (1965) has re
volutionized the nonlinear science by connecting the FPU problem to its co
ntinuum near-sonic limit described by the KdV equation. In integrable syst
ems solitary waves\, known as solitons\, are now well understood\, with on
e-dimensional Toda lattice being the most prominent example that has an ex
act solution covering a broad range of behaviors from delocalized low-ener
gy waves in the KdV limit to highly localized high-energy waves. Most disc
rete systems\, however\, are non-integrable. In this case understanding th
e transition from the KdV limit to the strongly discrete waves has mostly
relied on numerical and quasicontinuum approximations. In this introductor
y talk I will describe some of the important developments in this area.
