The Scientist' Guide to Optimization
Speaker: Sven Leyffer, Mathematics & Computer Science Division, Argonne National LaboratoryXSD Presentation
401/A1100 @ 1:30 PM
View Description
The Scientist' s Guide to Optimization has a few things to say on the subject of optimization. Optimization, it says, is about the most massively useful tool a scientist can have. Many design, data analysis, and operational problems can be formulated as optimization problems. We present a survey of current research trends in optimization motivated by applications of relevance to the APS. We will touch on applications such as accelerator design, image analysis, and optimal control. In all cases we will highlight the relevant software projects within Argonne' s Mathematics and Computer Science Division.

Open-Source Scalable Software for Fluid/Thermal Simulation
Speaker: Paul Fischer, Mathematics and Computing Science, Argonne National LaboratoryAES Seminar
401/A1100 @ 2:30 PM
View Description
This presentation provides an overview of an Argonne-developed open-source fluid/thermal simulation code designed for scalable parallel architectures. The code, Nek5000, is based on the spectral element method, which provides rapid numerical convergence that translates into relatively few grid points per wavelength for accurate simulation, particularly for long time-integrations that are characteristic of petascale applications.
Although originally designed (and widely deployed) as a fluid/thermal code, Nek5000 has proven to be a versatile framework for investigating new physics, discretizations, and numerical algorithms. With its open-source release, the code has been tested by a rapidly growing user community exploring a range of applications including combustion, heat transfer enhancement, MHD, ocean current modeling, reactor analysis, mixtures, reactive flow, turbomachinery, and vascular flow simulation. Its particular strengths are in stability, transition, and unsteady turbulent flow simulation. This talk will briefly cover the fundamental features of Nek5000 and provide some insight into its capabilities through several examples. Because the code is expendable with many potential applications (e.g., melting, sprays, fluid-structure interactions, high heat flux problems, etc.,) we seek new collaborations to expand its use to new and emerging fields and applications.

1st Annual KY Nanotechnology Symposium
APS DiscussionWestern Kentucky University, Carroll Knicely Center, Bowling Green, KY 42101
View Description
Bringing together micro and nanotechnology researchers within the South and Midwest regions, Western Kentucky University and the KY EPSCoR NanoNet are pleased to present the first annual Kentucky Nanotechnology Symposium which will be held March 30-31, 2012 at WKU in Bowling Green Kentucky.
The symposium is open to all scientists, engineers and students from a wide range of disciplines involved in microtechnology, nanotechnology and advanced materials.
The symposium promises to expand the awareness of core facilities that exist within the region and cultivate new research collaborations. Presentations focused on advanced material synthesis, metrology and characterization, devices, education, and core facilities will highlight the symposium.

National School on Neutron and X-ray Scattering
APS CourseView Description
The fourteenth annual National Neutron and X-ray Scattering School will
be held from August 12 to August 25, 2012 at Argonne and Oak Ridge National
Labs. This school provides graduate students with a comprehensive education
on the potential uses of the neutron and x-ray facilities in the United
States. Lectures, presented by researchers from academia, industry, and
national laboratories, will include basic tutorials on the principles of
scattering theory and the characteristics of neutron and synchrotron
radiation sources, as well as specialized talks on the application of
specific scattering techniques to a variety of scientific disciplines.
