Fall Meeting 2011
The Fall meeting will be held at 8:30 p.m. on WEDNESDAY, November 16, in the Clipper Room in Shriver Hall on the Homewood Campus of Johns Hopkins University. The speaker will be Dionisios Margetis, Associate Professor, Department of Mathematics and the Institute for Physical Science and Technology, and Center for Scientific Computation and Mathematical Modeling, University of Maryland, College Park. Professor Margetis will present a lecture entitled "A Tale of Two Scales: From Discrete Schemes to Partial Differential Equations in Epitaxial Growth." An abstract is below.
You are also cordially invited to attend the pre-lecture dinner with the speaker.
The pre-lecture dinner will be held at Gertrude's Restaurant in the Baltimore Museum of Art, which is next to the Johns Hopkins campus. Dinner will begin at 6:30 p.m.
Four entrees are available for your selection: Gertie's Crab Cake, Salmon alla Bella, Five-Spice Chicken, and Butternut Squash Ravioli. A set price of $36.00 is inclusive of salad, entree choice, all soft beverages (sodas, coffee, tea, etc.), a choice of dessert, tax and gratuity.
To attend the dinner, please send your check for the appropriate amount (made out to SIAM Washington- Baltimore Section) early enough to be received by Tuesday, November 8, 2011, to our Treasurer, Jeff Sieracki, PO Box 1011, College Park, MD, 20741.
PLEASE include your full name, email address and phone number with your check so that we can send you a confirmation of your reservation and may contact you in the event of any unexpected changes. If you cannot get your check to him by that date and you still want to come to dinner, then please email him by Tuesday, November 8, 2011, at [email protected]. We can accommodate at most fifteen diners on this occasion, so be sure to reserve in advance.
Title: A Tale of Two Scales: From Discrete Schemes to Partial Differential Equations in Epitaxial Growth
Dionisios Margetis, Associate Professor
Department of Mathematics, and Institute for Physical Science and Technology, and Center for Scientific Computation and Mathematical Modeling,
University of Maryland, College Park, MD 20742-4015.
Abstract: Epitaxial growth is a rapidly evolving area of research in which ideas of mathematics, physics and materials science fuse in order to advance knowledge of material surfaces and their properties. This talk will address recent progress, and open challenges, in establishing analytically a connection between two scales relevant to the morphological evolution of crystal surfaces. At the nanoscale, line defects (steps) of atomic size are evident; their motion is described by large systems of discrete schemes. At the macroscale, surfaces are plausibly described by nonlinear parabolic-type Partial Differential Equations (PDEs). The talk will focus on the challenging issue of making PDE-based predictions consistent with step motion.
The Homewood Campus of Johns Hopkins University is in Baltimore near 33rd and Charles Streets. The lecture will be held in the Clipper Room in Shriver Hall. Gertrude's Restaurant is in the Baltimore Museum of Art (BMA), which is next to the campus. You may refer to the Homewood Campus and Parking Map, available at http://www.parking.jhu.edu/general_maps.html, for the exact location of both venues.
Driving to BMA from I-695 (points East, North, and West): Take exit #23 to I-83 South (Jones Falls Expressway). Follow I-83 several miles to 28th Street eastbound exit. On 28th Street, go to the fourth traffic light, and turn left onto North Howard Street. Go one block on Howard Street, crossing 29th Street, and bear right at the fork onto Art Museum Drive. The BMA will be on your left.
There are three parking options:
- On-Street metered parking along Art Museum Drive --
E-Z Park Meters accept coins, debit cards, and credit cards. After pre-paying, simply display the printed parking receipt on the dashboard of your vehicle. The rate is $0.50 per hour.
- BMA-Gated Parking Lots--
There is a flat parking rate of $6 from 5 p.m. until midnight.
- JHU Homewood Campus (South Parking Garage and Metered Faculty Lots)--
You may refer to http://www.parking.jhu.edu/general_maps.html, for visitor parking locations. There is a flat parking rate of $6 from 3:45 p.m. until midnight at the garage, and $2 per hour at the meters with a maximum charge of $6, valid until the end of the day.
