You are cordially invited to the first IACS Seminar of the new academic year. Also please
note below that we are launching a new course and a new course category, Applied
Computation, this fall.
Seminar speaker: Nicolas Hadjiconstatinou, MIT
Location: Maxwell Dworkin G125, 33 Oxford Street, Cambridge
Date: Friday, Sept. 7
Time: Informal lunch with speaker, 12:30pm. Talk, 1:00pm.
Title: Efficient Simulation of Multiscale Kinetic Transport
Abstract:
This talk will discuss a new class of approaches for simulating multiscale kinetic
problems, with particular emphasis on applications related to small-scale transport. These
approaches are based on an algebraic decomposition of the distribution function into an
equilibrium part, described deterministically (analytically or numerically), and the
remainder, described using a particle simulation method. The discussion will pay
particular attention to stochastic particle simulation methods that are typically used to
simulate kinetic phenomena. Algebraic decomposition can be thought of as control-variate
variance-reduction formulation, with the nearby equilibrium serving as the control. Such
formulations can provide substantial computational benefits; in many cases, the
computational cost reduction is sufficiently large to enable otherwise intractable
simulations. The proposed methods will be illustrated with a variety of problems of
engineering interest, such as microscale/nanoscale gas flows.
Bio:
Nicolas Hadjiconstantinou is professor of mechanical engineering and Director of
Computation for Design and Optimization at MIT. He holds BA and MA degrees in engineering
from the University of Cambridge (UK), an SM degree in physics from MIT and a PhD in
mechanical engineering from MIT. After completing his PhD in 1998, he spent a year at
Lawrence Livermore National Laboratory as a Lawrence Livermore Fellow working with Berni
Alder on computational kinetic theory. He then joined the faculty of the Mechanical
Engineering Department at MIT, where he is now Professor. His interests include molecular
simulation methods, microscale fluid mechanics and transport theory. He is a Fellow of the
American Society of Mechanical Engineers (ASME) and was recently presented the 2012 Gustus
L. Larson Memorial Award.

COURSE ANNOUNCEMENT
Number: Applied Computation 263
Title: Data and Computation on the Internet
Meets: 4-5:30 pm Monday/Wednesday Maxwell Dworkin G125
Instructor: Ian Stokes-Rees, Lecturer in Computational Science
<ijstokes@seas.harvard.edu<mailto:ijstokes@seas.harvard.edu>>
Course website:
http://iacs.seas.harvard.edu/courses/ac263
Description: From TCP/IP to HTTP, this course will present the architecture of the
Internet and how it has become a key part of modern large-scale data processing and
computation. We will explore low-level protocols and standards, look at data storage and
movement over wide area networks, and consider how modern science, commerce and society
have come to rely on the Internet and the Web.
The course will emphasize web- based interaction patterns for data and computation.
Grading will be based on a mixture of reading responses, programming assignments and
systems labs, culminating in a team systems + programming project. Class and section time
will include tutorials, demonstrations and mini programming and systems exercises. There
will be guest lectures on state-of-the-art Internet-oriented systems and “Grand
Challenges” for large-scale data and computation.
