Dynamics and Control of Large Utility-Scale Wind Turbines for Fun and Profit
Wed, Oct 19, 2011 @ 10:00 AM - 11:00 AM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Mark Balas, University of Wyoming
Talk Title: Dynamics and Control of Large Utility-Scale Wind Turbines for Fun and Profit
Abstract: The next generation of utility-scale wind turbines will be larger and more flexible than earlier designs to
promote greater energy capture and reduce the cost of energy. It is here that the implementation of active
feedback control is crucial to meet design objectives. Not only must there be power regulation or optimization
but also load mitigation to extend the life of the turbine. Wind turbine dynamics modeling for active control is
composed of four principal parts:
1. Aerodynamics and Inflow Behavior,
2. Structural Dynamics,
3. Feedback Control Algorithms,
4. Power Electronics
Active control is a relatively new technology for wind turbines. Basic control theory used in this talk is linear
time-invariant and periodic control using disturbance accommodation, but with a strong connection to the
aerodynamics and structural dynamics of wind turbines. New work in adaptive control of wind turbines will
also be presented.

The Quest for a Quantum Simultaneous Decoder
Wed, Oct 19, 2011 @ 01:00 PM - 02:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Mark M. Wilde, McGill University
Talk Title: The Quest for a Quantum Simultaneous Decoder
Abstract: Almost every channel coding theorem in classical information theory exploits a decoding technique known as "jointly typical decoding." The decoder asks the simple question: "Is the received sequence jointly typical with a sequence in the codebook?" and if so, it decides that the received sequence corresponds to the sequence with which it is jointly typical. If the choice of the code is random, then it is possible to bound the expected transmission error probability by exploiting a union bound and the properties of typicality, as long as the number of messages is not too large. The analogous decoding technique in the quantum world is not so easy. Despite Holevo, Schumacher, and Westmoreland's (HSW) early success in constructing a decoding POVM that resembles a jointly typical decoder, it is not immediately clear how the technique extends to multiparty quantum information theory. Furthermore, it is imperative to show that such a decoding POVM works if we would like to "quantize" the best known achievable rate region for the quantum interference channel. In this talk, I'll update the progress of the McGill quantum information group on solving the quantum simultaneous decoder conjecture. We have now solved it for the case of two senders, but it is not immediately clear how to extend the proof to the case of three senders.
This work is based on a collaboration with Omar Fawzi, Patrick Hayden, Ivan Savov, and Pranab Sen in arXiv:1102.2624 .
Biography: Mark M. Wilde received the B.S. degree in computer engineering from Texas A&M University in 2002, the M.S. degree in electrical engineering from Tulane University in 2004, and the Ph.D. degree in electrical engineering from the University of Southern California in 2008. Currently, he is a Postdoctoral Fellow with the School of Computer Science, McGill University. He has published over 45 articles and preprints in the area of quantum information processing. His current research interests are in quantum error correction and quantum Shannon theory, and he is the author of the recent text "From Classical to Quantum Shannon Theory."

CommNetS Seminar: Net Neutrality & Wireless Net Neutrality: Why Network Researchers Should Care
Wed, Oct 19, 2011 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Prof. Scott Jordan, University of California, Irvine
Talk Title: Net Neutrality & Wireless Net Neutrality: Why Network Researchers Should Care
Series: Communications, Networks & Systems (CommNetS) Seminar
Abstract: Abstract: Net neutrality has become one of the hottest debates about communications public policy. Itâs resolution, or lack thereof, will largely determine whether and how Quality-of-Service mechanisms are deployed in the Internet. I will propose a unified net neutrality policy that applies both to wireline and wireless Internet. The policy is grounded in both communications law and Internet architecture. I will discuss how technical differences between wired and wireless networks should determine reasonable traffic management, and how net neutrality should address Quality of Service requirements of specialized and other services. I will argue that communication service providers should be able to charge both residential and business users for bandwidth and Quality of Service, but not to restrict applications.
Biography: Bio: Scott Jordanâs research interests include communications policy, pricing and differentiated services in the Internet, and resource allocation in wireless multimedia networks. In the communications policy area, he is working on network neutrality and traffic management. He is developing moderate network neutrality policies founded on network architecture that encourage development of network management for multimedia applications while prohibiting anti-competitive behavior. In the networks technology area, he is working on the integration of voice, data, and video on the Internet and on wireless networks. Professor Jordan received the Ph.D. degree in Electrical Engineering & Computer Science from the University of California, Berkeley. He has served as an IEEE Congressional Fellow, working in the United States Senate on Internet and telecommunications policy issues, and on the FCC Open Internet Technical Advisory Committee.

Quantitative Body Dynamic Contrast Enhanced MRI
Wed, Oct 19, 2011 @ 03:45 PM - 04:45 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Kyunghyun (Kyung) Sung, PhD, Department of Radiology, Stanford University
Talk Title: Quantitative Body Dynamic Contrast Enhanced MRI
Abstract: Dynamic contrast enhanced MRI (DCE-MRI) detects spatial and temporal variations in signal enhancements and can offer a measure of microvascular structure and pathology. Pharmacodynamic biomarkers, provided by quantitative DCE-MRI, have a promising future to be used to monitor tumor response to treatment, but there still exist several challenges to ensure consistent and reliable quantitative DCE-MRI results across different clinical trials in oncology.
In this talk, we describe our recent technical developments to overcome these challenges by 1) improving spatial- and temporal-resolution of MRI using two novel compressed sensing methods, 2) increasing accuracy of T1 measurements with B1 inhomogeneity correction in 3T breast MRI, and 3) easily facilitating data analysis of quantitative DCE-MRI with our software developments (OsiriX plug-ins). Such developments can potentially offer more robust and reproducible measures of microvascular parameters associated with human cancers.
Biography: Kyung Hyun Sung is a Research Associate in the Department of Radiology at Stanford University. He joined the Body Magnetic Resonance (BMR) Group (directed by Brian Hargreaves), which is part of the Radiological Sciences Lab, after completing the PhD program (advised by Prof.Krishna Nayak) in the Electrical Engineering Department at the University of Southern California.
His research interests include Dynamic Contrast Enhanced (DCE) MRI, Compressed Sensing (CS), and Fat/Water separation.
