Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Sergio Boixo, Harvard University
Talk Title: Quantum Engineering
Abstract: Quantum engineering is the direct use of quantum mechanics to improve some aspect of an engineering task beyond what is possible using classical physics. Out of the many facets of quantum engineering I will focus on three: measurement (quantum metrology), communication and adiabatic quantum computation. I will emphasize devices currently being tested. We proposed recently a general method for quantum metrology which uses quantum interactions to increase the sensitivity of high-precision measurements. This method has now been demonstrated experimentally, and the number of applications is growing. Adiabatic quantum computation has inspired a new type of processor currently under development.
Biography: Sergio Boixo is currently a postdoc at the Aspuru-Guzik's research group at Harvard University. Previoulsy he was a postdoc at the Institute for Quantum Information (IQI) at Caltech. He obtained a Master of Physics at the Universidad Autonoma de Barcelona (UAB) and a Ph.D. in Physics at University of New Mexico (UNM), while also doing research at Los Alamos National Laboratory. Sergio Boixo has undergraduate degrees in computer engineering, philosophy, and mathematics.

Multi-Disciplinary Technology Applications in the Energy Industry
Mon, Apr 04, 2011 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Fred Aminzadeh, Research Professor, Mork Family Department of Chemical Engineering and Materials Science
Talk Title: Multi-Disciplinary Technology Applications in the Energy Industry
Abstract: What are the significant technology advances in the energy industry in the past decade? What are current trends? What advanced computing technologies are continuing to have an impact on oil and gas exploration? How best we can use new signal processing and pattern recognition techniques to get the most out of the seismic data? Where do we want to be within the next ten years? What do we need to do to address challenges associated with declining oil fields and how the EE discipline can help? These questions will be addressed in conjunction with our most challenging exploration and field development problems. The need for cross disciplinary research and true integration will be discussed.
Some of the answers to the above questions may have a direct impact on the direction of the Reservoir Monitoring Consortium (RMC) being launched at USC. The RMC, with input from faulty from many departments, will look at the whole value chain in reservoir monitoring. It will focus on the data integration and data mining (eg 4D seismic, production data, passive seismic data), visualization and updating of reservoir model and real time reservoir management. It will also look into new techniques in soft computing signal and image processing to analyze and interpret the time lapse seismic and passive seismic data. Some of such applications will be demonstrated by a few recent real life examples, including a recently funded $2 million dollars DOE project for geothermal applications.
Biography: Fred Aminzadeh is a research professor at the Petroleum Engineering program at USC. Upon receiving his PhD in Control Theory in 1979 from USC, he went to Bell Laboratories in Murray Hill, NJ. Subsequently he joined Unocal with both technical and management responsibilities.

Models, Optimization and Control of Collective Phenomena in Power Grids
Tue, Apr 05, 2011 @ 02:30 PM - 03:30 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Michael Chertkov, Los Alamos National Lab
Talk Title: Models, Optimization and Control of Collective Phenomena in Power Grids
Series: CEI Distinguished Lecture Series in Energy Informatics
Abstract: We are asking modern power grids to serve under conditions it was not originally designed for. We also expect the grids to be smart, in how they function, how they withstand contingencies, respond to fluctuations in generation and load, and how the grids are controlled. To meet these ever increasing expectations requires extending power grid models beyond the scope of the traditional power engineering.
In this talk Dr. Chertkov will first review basics of power flows, and then outline a number of new problems in modeling, optimization and control theory for smart grids. In particular, the talk will describe new approaches to control of voltage and reactive flow in distribution networks, algorithms to study distance to failure, and statistical analysis of cascading blackouts in transmission networks.
Biography: : Dr. Chertkov's areas of interest include applied and theoretical problems in power systems, hydrodynamics, statistical and mathematical physics, information theory and computer science. Dr. Chertkov received his Ph.D. in physics from the Weizmann Institute of Science in 1996, and his M.Sc. in physics from Novosibirsk State University in 1990. After his Ph.D., Dr. Chertkov spent three years at Princeton University as a R.H. Dicke Fellow in the Department of Physics. He joined Los Alamos National Lab in 1999, initially as a J.R. Oppenheimer Fellow in the Theoretical Division. He is now a technical staff member in the same division. Dr. Chertkov has published more than 100 papers in these research areas and is currently leading "Physics of Algorithms"
and "Optimization and Control Theory for Smart (Power) Grids" projects at LANL.

Electrical Engineering Distinguished Lecturer Series
Wed, Apr 06, 2011 @ 04:30 PM - 05:30 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Kathy Yelick, University of California at Berkeley and Lawrence Berkeley National Laboratory (LBNL)
Talk Title: Exascale Computing: More and Moore?
Abstract: With petascale systems becoming broadly available in high end computing, attention is now focused on the challenges associated with the next major performance milestone: exascale computing. Demand for computational capability grows unabated, with areas of national and commercial interest including global climate change, alternative energy sources, defense and medicine, as well as basic science. Past growth in the high end has relied on a combination of faster clock speeds and larger systems, but the clock speed benefits of Mooreâs Law have ended, and 200-cabinet petascale machines are near a practical limit. Future system designs will instead be constrained by power density and total system power demand, resulting in radically different architectures. The challenges associated with exascale computing will require broad research activities across computer science, including the development of new algorithms, programming models, system software and computer architecture. While these problems are most evident at the high end, they limit the growth in computing performance across scales, from hand-held client devices to personal clusters and computational clouds.
In future computing systems, performance and energy optimization will be the combined responsibility of hardware and software developers. Since data movement dominates energy use in a computing system, minimizing the movement of data throughout the memory and communication fabric are essential. In this talk I will describe some of the open problems in programming models and algorithms design and promising approaches used so far. These will build on the ideas of Partitioned Global Address Space languages and Communication Avoiding algorithms, but extended to more complex memory hierarchies. In addition to these universal problems, fault resilience is a problem at the high end that will require novel system support, possibly propagating up the software stack to user level software and algorithms. Overall, the trends in hardware demand that the community undertake a broad set of research activities to sustain the growth in computing performance that users have come to expect.
Biography: Kathy Yelick is the Associate Laboratory Director for Computing Sciences and the Director of the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory (LBNL). She is also a Professor of Electrical Engineering and Computer Sciences at the University of California at Berkeley. She is the author or co-author of two books and more than 100 refereed technical papers on parallel languages, compilers, algorithms, libraries, architecture, and storage. She co-invented the UPC and Titanium languages and she co-developed techniques for self-tuning numerical libraries, including the first self-tuned library for sparse matrix kernels. Her work includes performance analysis and modeling as well as optimization techniques for memory hierarchies, multicore processors, communication libraries, and processor accelerators. She earned her Ph.D. in EECS from MIT and has been a professor at UC Berkeley since 1991 with a joint appointment at LBNL since 1996

Here we focus on this critical concept using semiconductor nanowires, which provide the capability for synthetic design to realize unprecedented structural and functional complexity in building blocks, as a platform material. First, a brief review of the synthesis of complex modulated nanowires in which rational design can be used to precisely control composition, structure and most recently structural topology will be discussed. Second, the unique functional characteristics emerging from our exquisite control of nanowire materials will be illustrated with several selected examples from nanoelectronics, quantum electronics and nano-enabled energy. Third, the remarkable power of nanowire building blocks will be further highlighted through their capability to create unprecedented active electronic interfaces with biological systems. Recent work pushing the limits of both multiplexed extracellular recording at the single cell level and the first examples of intracellular recording will described, as well as the prospects for truly blurring the distinction between nonliving and living information processing systems.

Speaker: Wei Wu, Senior Scientist, HP Labs, Hewlett-Packard Co.
Talk Title: Nano-Crossbar Circuits, Optical Meta-Materials and SERS Sensors
Abstract: Semiconductor industry has enjoyed great successes by following the âMooreâs lawâ for more than four decades. With the end of the roadmap looming in the horizon, great efforts have been made to look for the alternatives for âpost-Siâ electronics. I will present our work on crossbar circuits, especially crossbar memory circuits based on transition metal oxide (i.e. memristor). Memristor is a type of resistive RAM device. It stores the information by ion movements inside the switching material, instead of charge trapping as in other conventional memory devices. We have demonstrated several generations of crossbar memory circuits with record-high densities, and have also integrated memristor and Si CMOS circuits successfully. The technologies developed for nano-electronics were applied to several other areas. One example I would like to share is optical negative meta-materials (NIMs) at near-IR range. That includes NIMs with negative reflective index (both negative permittivity and permeability) at 1.55 m range, fast modulation of NIMs and non-linear effects of NIMs. Another example is highly sensitive surface enhanced Raman spectroscopy (SERS) sensors fabricated using the 3-D nano-patterning technology we developed. The end of roadmap may be getting closer, but it is just the start of a new era, where we can leverage on what we have been developing in the past and make great impacts on the whole society.
Biography: Wei Wu graduated from Peking University with a BS in Physics in 1996, and received a Ph.D. in Electrical Engineering from Princeton University in 2003. He joined HP labs in 2003, and he is a senior scientist at nano-electronics research group (formerly known as quantum science research). His work on nanoimprint lithography has enabled nano-electronic and nano-photonic applications at HP labs for the last seven years. His work includes crossbar memory (i.e. memristor) and logic circuits with the record high densities, the first nanoimprint-fabricated optical negative index meta-material at 1.55m range, the first optical modulation using negative index meta-material at near-IR, the first third harmonic generation using meta-material, highly sensitive surface enhanced Raman sensors fabricated using 3-D nanoimprint, the first room-temperature working single electron memory and the first large area bit-patterned magnetic media fabricated using nanoimprint. The nanoimprint machine he invented has been commercialized via IP licensing. He coauthored 65 peer reviewed journal papers and more than 60 conference presentations, including 10 keynote and invited presentations. He has 49 granted US patents and 77 pending applications. He is serving as HPâs representative at SEMATECH lithography program advisory group. He is a senior member of IEEE and serving in the executive committee of IEEE SFBA nanotechnology council.

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Professor Stephen J. Riederer, Mayo Clinic, Rochester, MN.
Talk Title: Contrast Enhanced MR Angiography, Recent Improvements in Resolution, Application, and Coverage
Abstract: Although MR Angiography (MRA) has been under study for well over two decades, the field still continues to advance. The technical innovations of parallel data acquisition, specific k-space data sampling methods, and high-count receiver coil arrays can be integrated to allow marked reductions in the acquisition times necessary to form high quality 3D MR angiograms with comparable or even improved spatial resolution compared to a decade ago. If implemented with appropriately designed receiver coil arrays, the loss of SNR can be carefully controlled. Advanced k-space sampling methods reduce the sensitivity of the reconstructed images to temporal blurring and allow time-resolved results which can readily distinguish arterial from venous phases in problematic cases. Further extensions permit high quality, multi-station imaging of the peripheral vasculature. In this presentation these methods will be described, and in vivo results from multiple vascular territories will be presented.

Fri, Apr 22, 2011 @ 10:00 AM - 11:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Nidhi, Electrical and Computer Engineering Department at UCSB
Talk Title: Self-Aligned N-Polar GaN HEMTs: Towards Next-Generation Nitride Electronics
Abstract: III-Nitrides have emerged as a versatile new material family with unique material properties such as large piezoelectric polarization, high saturation velocity, high breakdown electric field and bandgap ranging from near IR (0.7 eV for InN) to deep UV (6.4 eV for AlN). This wide range of band-gap allows them to be extensively used in opto-electronics in a large range of wavelength, optical storage and high efficiency photovoltaics using InGaN alloys. Recently, AlGaN/GaN high-electron-mobility transistors (HEMTs) have also been widely used as power amplifiers for wireless communication applications and as power switches for rectification.
In this talk, I will emphasize on the N-polar orientation of GaN and its application towards high frequency electronics. N-polar GaN-based HEMTs offer several advantages over the more established Ga-polar technology such as the potential of ultra low ohmic contact resistance (20 Ω-µm demonstrated) and a natural back-barrier for charge confinement. The development of N-polar GaN electronics started late due to materials and processing challenges, but has been eventful with several significant achievements in the recent past. I will talk about the self-aligned MIS-HEMT technology we developed at UCSB and its development towards becoming a competitor to the established Ga-polar technology. Finally, I will discuss future directions for III-Nitride electronics and other exciting possibilities employing the novel materials.
Biography: Nidhi is a Ph.D candidate under Prof. Umesh Mishra in the Electrical and Computer Engineering Department at UCSB (University of California Santa Barbara). Her graduate work involved design and fabrication of N-polar GaN-based self-aligned MIS-HEMTs for very high frequency applications, like mm-wave power and possibly digital applications due to gate-first self-aligned design. She received the M. S. in Electrical and Computer Engineering from UCSB in 2008. She graduated second in her class of Electrical Engineering from Indian Institute of Technology, Kanpur, India with a Bachelor of Technology degree in 2006. Her research interests include deep submicron devices for high frequency applications, nanoscale semiconductor devices, power electronic devices and novel device structures on new materials for faster and energy-efficient electronics with expanded functionality.

Integrating speech science and technology: New models for speech and audio processing
Tue, Apr 26, 2011 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Eric Fosler-Lussier, The Ohio State University
Talk Title: Integrating speech science and technology: New models for speech and audio processing
Abstract: Traditional speech recognition techniques adopt a hierarchical, top down approach to modeling speech data; linguistic information such as word pronunciations or language models typically act as priors in statistical models for automatic speech recognition (ASR). One line of research has started to integrate linguistic information within the representation of the underlying speech data. However, the top down approach typically used in ASR (Hidden Markov Models) does not easily allow for combining evidence from different linguistic representations.
Similarly, in speech separation (removing background noise from a speech-noise mixture), different cues have been identified that indicate speech or background noise. However, the techniques that have utilized multiple cues typically combine them in an ad hoc manner.
In this talk, I will discuss a line of research from my lab that looks at combining evidence using Conditional Random Fields: CRFs have been utilized within the NLP community for many tasks, but their use in the speech community is only starting to take off. Applications of CRFs to the ASR and speech separation problems show that this type of model can be an effective combiner of information, and can allow us to easily integrate ideas from speech science into working systems.
Biography: Eric Fosler-Lussier is an Associate Professor of Computer Science and Engineering, with a courtesy appointment in Linguistics, at The Ohio State University. After receiving a B.A.S. (Computer and Cognitive Science) and B.A. (Linguistics) from the University of Pennsylvania in 1993, he received his Ph.D. in 1999 from the University of California, Berkeley, performing his dissertation research at the International Computer Science Institute under the tutelage of Prof. Nelson Morgan.
