Talk Title: TBA
Series: EE598 Seminar Course
Abstract: Weekly seminars given by researchers in academia and industry including senior doctoral students in EE, CS and ISI covering current research related to parallel and distributed computation including parallel algorithms, high performance computing, scientific computation, application specific architectures, multi-core and many-core architectures and algorithms, application acceleration, reconfigurable computing systems, data intensive systems, Big Data and cloud computing.
Biography: Prerequisite: Students are expected to be familiar with basic concepts at the level of graduate level courses in Computer Engineering and Computer Science in some of these topic areas above. Ph.D. students in Electrical Engineering, Computer Engineering and Computer Science can automatically enroll. M.S. students can enroll only with permission of the instructor. To request permission send a brief mail to the instructor in text format with the subject field ââ¬ÅEE 598ââ¬Â. The body of the mail (in text format) should include name, degree objective, courses taken at USC and grades obtained, prior educational background, and relevant research background, if any.
Requirements for CR:
1. Attending at least 10 seminars during the semester
There will be a sign-in sheet and a sign-out sheet at every seminar. All students must sign-in (before 2:00pm) and sign-out (after 3:00pm). The sign-in sheet will not be available after 2:00pm, and the sign-out sheet will not be available before 3:00pm.
2. Submitting a written report for at least 5 seminars
The written report for each seminar must be 1-page single line spaced format with font size of 12 (Times) or 11 (Arial) without any figures, tables, or graphs. The report must be submitted no later than 1 week after the corresponding seminar, and must be handed only to the instructor either on the seminar times or during office hours. Late reports will not be considered.
The report must summarize studentââ¬â¢s own understanding of the seminar, and should contain the following:
- Your name and submission date [1 line]
- Title of the seminar, name of the speaker, and seminar date [1 line]
- Background of the work (e.g., applications, prior research, etc.) [1 paragraph]
- Highlights of the approaches presented in the seminar [1-2 paragraphs]
- Main results presented in the seminar [1-2 paragraphs]
- Conclusion (your own conclusion and not what was given by the speaker) [1 paragraph]
Reviewing papers related to the topic of the seminar, and incorporating relevant findings in the
reports (e.g., in the conclusion section) is encouraged. In such cases, make sure to clearly indicate
the reference(s) used to derive these conclusions.

Astani CEE Dept. Seminar

Talk Title: Optimization of Computationally Expensive Environmental Models Including Application to Monitoring Multi-Phase Subsurface flow from Carbon Sequestration
Abstract: This talk will first give an overview of my research on optimization and uncertainty quantification and its application to a range of environmental topics. Our new algorithms (available as open source software) are very efficient for these applications and other multi-modal, computationally expensive simulation models because the algorithms are designed to reduce significantly the number of simulations required for finding the global optimal solution to a problem with multiple local minima. Our approach is to iteratively approximate the objective function or likelihood function f(x) with Radial Basis Functions (RBF) based on all previous simulations to guide the selection of the next expensive function evaluation. The applications incorporate issues related to monitoring, forecasting, uncertainty quantification, and risk analysis as well parameter estimation and design.
Estimation of sequestered CO2 and pressure plumes is very important for risk analysis but difficult because the multiphase PDE model is very nonlinear and computationally expensive, monitoring data is very sparse, and the inverse optimization problem has multiple local minima. Each objective function evaluation requires expensive forward simulation of 3-D, highly nonlinear, multi-phase, multi-constituent set of PDEs (which can take hours per simulation). Iââ¬â¢ll present results using TOUGH2 that give good current estimates and forecasts of plumes with our global optimization algorithm Stochastic RBF with a small number of original model simulations, and Iââ¬â¢ll use our SOARS algorithm to assess uncertainty.
Biography: Prof. Shoemaker received a PhD in Mathematics from USC supervised by Richard Bellman on dynamic programming and control. She is interested in surface and subsurface contaminant transport applications as well as in developing new computationally efficient distributed (HPC) optimization and control methods. Environmental topics she has worked on include watershed contaminant transport, groundwater remediation, global climate models (CLM4.5) and optimization of stochastic hydropower systems (BPA). . She is a member of the National Academy of Engineering and a Distinguished Member in ASCE. She is also a Fellow in INFORMS (Operations Research) and in AGU (hydrology).

EE 598: ELECTRICAL ENGINEERING RESEARCH SEMINAR COURSE #14
Thu, May 02, 2013 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Charalampos Chelmis, PhD Candidate, Computer Science, USC Viterbi School of Engineering
Talk Title: Computational Models of Technology Adoption at the Workplace
Series: EE598 Seminar Course
Abstract: Despite numerous studies in Online Social Networks, little is known about network dynamics and information diffusion processes at the workplace, where professional relationships are formed not because of similarity but instead due to a formal, imposed structure. In an enterprise, understanding how information flows within and between organizational levels and business units is of great importance. In this talk, we emphasize the impact of organizational hierarchy on adoption of new technologies in the enterprise. We present two intuitive, realistic agent-based computational models that capture the dynamics of adoption at both microscopic and macroscopic levels in a real-world dataset we collected from a multinational Fortune 500 company.
Biography: Charalampos Chelmis is a PhD candidate in Computer Science working with Prof. Viktor K. Prasanna in the Ming Hsieh Department of Electrical Engineering at the University of Southern California, Los Angeles. His research focuses on modeling complex networks, their properties, hidden structures and dimensional interdependencies, mining large-scale, real-world social networks, and designing efficient, scalable algorithms by combining Graph Theory and Semantic Web Technologies, Big Data Analytics and Machine Learning, sociometric features and measures. His research has been published at top venues, including SocialCom, ASONAM, TOIS and SNAM. He received his Master of Science in Computer Science from the University of Southern California in 2010 and his Bachelor in Computer Engineering & Informatics from the University of Patras, Greece in 2007.

SWITCH movie screening
Thu, May 02, 2013 @ 06:30 PM - 08:30 PM
Viterbi School of Engineering Student Organizations
Student Activity
May 2nd, 2013
Taper Hall of Humanities (THH 101), 6:30PM
RSVP: www.bit.ly/switchrsvp
The USC Energy Club, Marshall Net Impact, and Political Students Assembly are proud to bring you, Switch, a documentary looking into our energy future with a Q&A session afterwards with Dr. Scott W. Tinker.
In 2009, documentary filmmaker Harry Lynch and geologist Dr. Scott W. Tinker set out to make a film on our energy transition. The goal was not to advocate for one technology over another, not to suggest how the transition should happen â but to try to determine how it actually would happen, based on scientifically-sound investigation and the practical realities of the world of energy as we discovered them. The result is Switch.
Please join us for a memorable night!Location: Mark Taper Hall Of Humanities (THH) - 101
