Task-Based Optimization for Medical Imaging
Tue, Sep 03, 2013 @ 10:00 AM - 11:00 AM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Prof. Angel Pineda, Cal-State Fullerton
Talk Title: Task-Based Optimization for Medical Imaging
Series: Medical Imaging Seminar Series
Abstract: Medical images are typically obtained with a clinical task in mind. These tasks can often be modeled as signal detection or parameter estimation. In this talk, we will define the information content of medical images based on the performance of mathematical models for clinical tasks using those images. To quantify this type of information content we need to define the task (the intended use of the images), the statistics (the sources of variability in the data), and the observer (how we intend to obtain the information from the images). This ââ¬Åtask-basedââ¬Â optimization can be used in a wide variety of settings. Examples will include choosing which data to acquire in optical diffusion tomography, optimizing a tomosynthesis system for lung nodule detection and deciding whether or not to accelerate the reconstruction of x-ray CT by binning the projection data. At the end of the talk we will discuss how this type of optimization could be used in MRI
Biography: Dr. Angel Pineda is an associate professor of mathematics at California State University, Fullerton. For the 2013-14 academic year he is a visiting scholar at the Magnetic Resonance Imaging Laboratory at University of Southern California.

Speaker: Jerry M. Woodall, Distinguished Professor of Electrical and Computer Engineering, University of California, Davis
Talk Title: High Impact Alternative R&D at a University
Abstract: This presentation is about game changing alternative energy R&D at a university. This is not an easy career path, because if you have a great idea that will likely be a game changer, but not on some agency’s roadmap, you most likely won’t get funded. This is why most tenure track and mid-career professors chose to chase the money in-stead. This situation is particularly onerous for those working in the alternative energy fields such as photovoltaics (PVs), energy storage, and energy conversion. And because agencies fund “roadmaps” rather than fund track record and great practical ideas that could lead to “products” and not just mostly unread Ph.D theses, the US will not be among those nations who reap the economic benefits of the alternative energy industries. In spite of this situation I have chosen to work on high impact alternative energy projects. My presentation will cover the highlights of my self-defined alternative energy programs, which, if successful, will lead to new alternative energy products. These include a solar power conversion project and a project that uses bulk aluminum rich alloys for large scale and safe energy storage, which splits water to make hydrogen on-demand. My presentation will include a discussion of why, in my opinion, the government funding agencies are not supporting the academic community in performing high risk but high impact R&D so desperately needed by the US technology based economy.
Biography: Jerry M. Woodall, a National Medal of Technology Laureate, and Distinguished Professor of Electrical and Computer Engineering at UC Davis, received a B.S. in metallurgy in 1960 from MIT. In 1982, he was awarded a Ph.D. in Electrical Engineering from Cornell University. He pioneered and patented the development of GaAs high efficiency IR LEDs, used in remote control and data link applications such as TV sets and IR LAN. This was followed by the invention and seminal work on gallium aluminum arsenide (GaAlAs) and GaAlAs/GaAs heterojunctions used in super-bright red LEDs and lasers found in, for example, CD players and short link optical fiber communications. He also pioneered and patented the GaAlAs/GaAs heterojunction bipolar transistor used in, for example, cellular phones. Also, using GaAs/InGaAs strained, non-lattice-matched heterostructures, he pioneered the “pseudomorphic” high electron mobility transistor (HEMT), a state-of-the-art high speed device widely used in cellular phones. He is cur-rently developing a high speed, high power HBT fabricated with merged III-V and III-N materials, small scale photo thermal solar energy converters, and developing a new company to market ultra high purity hydrogen and UHP alumina by splitting water with aluminum-gallium alloys.

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Ken Cooper, Jet Propulsion Laboratory
Talk Title: Terahertz Imaging Radar for Personal Screening Applications
Abstract: A summary of the NASA Jet Propulsion Laboratory’s 675 GHz imaging radar will be presented, with an emphasis on several key design aspects that enable fast, reliable through-clothes imaging of person-borne concealed objects for standoff ranges out to 40 m. These include a frequency-modulated continuous-wave (FMCW) radar technique with a 30 GHz bandwidth to achieve sub-centimeter range resolution, software to compensate for signal distortion and generate clear imagery, a low-noise microwave chirp generator, and a high-performance 675 GHz transceiver. The radar’s optical design will also be described, which enables fast beam scanning for real-time frame rates of 4 Hz, as well as agile re-focusing over a large fractional range swath. Still faster speeds are on the horizon as multi-beam THz transceivers are developed.
Biography: Ken Cooper received an A.B. degree in physics from Harvard College in 1997, and a Ph.D. degree in physics from the California Institute of Technology in 2003.

Non-Gaussian Image Structure, and the Rationale for Tomographic Image Reconstruction
Tue, Sep 10, 2013 @ 10:00 AM - 11:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Craig Abbey, UC Santa Barbara
Talk Title: Non-Gaussian Image Structure, and the Rationale for Tomographic Image Reconstruction
Series: Medical Imaging Seminar Series
Abstract: Gaussian stochastic processes are a common model for medical and scientific images, leading to Gaussian statistical properties characterized by mean, variance, and correlations. However it is clear that real image ensembles have higher-order non-Gaussian structures that are not fully described by these statistics. Furthermore, studies in vision science suggest that he visual system is tuned to these non-Gaussian components.
This seminar will present one way to quantify non-Gaussian statistical structure in images, called Laplacian fractional entropy (LFE). We will then see some ways that LFE is influenced by factors of interest in medical imaging, such as image processing of full-field digital mammograms or different breast imaging technologies. Finally, we will consider the rationale for tomographic reconstruction of projection images, using LFE to address the possibility that the primary benefit of image reconstruction is to repackage the statistical properties of the acquired data.
Biography: Craig K. Abbey received his PhD in applied mathematics from the University of Arizona in 1998. He was a postdoctoral fellow in medical physics at Cedars-Sinai Medical Center and UCLA from 1998 to 2001. From 2001 to 2004 he was a member of the faculty in biomedical engineering at UC Davis, where he retains an adjunct position. His primary affiliation is in the Dept. of Psychological and Brain Science at UC Santa Barbara. His research focuses on how useful information is extracted from images in the presence of noise and other signal distortions. Methods for investigating this topic include theoretical analysis of image statistics as well as visual psychophysics for evaluating human observer performance.

CENG Seminar - CANCELED
Mon, Sep 16, 2013 @ 10:00 AM - 11:30 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Rahul Mangharam, Ph.D. , University of Pennsylvania
Talk Title: “Closing-the-loop with Cyber Physical Systems”
Abstract: Cyber-Physical Systems are the next generation of embedded systems with the tight integration of computing, communication and control of “messy” plants. I will describe our recent efforts in modeling for scheduling and control of closed-loop Cyber-Physical Systems across the domains of medical devices, energy-efficient buildings, wireless control networks and programmable automotive systems.
In medical devices: the design of bug-free and safe software is challenging, especially in complex implantable devices that control and actuate organs whose response is not fully understood. Safety recalls of pacemakers and implantable cardioverter defibrillators between 1990 and 2000 affected over 600,000 devices. Of these, 200,000 or 41%, were due to software issues that continue to increase in frequency. There is currently no formal methodology or open experimental platform to test and verify the correct operation of medical device software within the closed-loop context of the patient. I will describe our efforts to develop the foundations of formal modeling, synthesis and development of verified medical device software and systems from verified closed-loop models of the pacemaker and the heart (more details here.)
In buildings: heating, cooling and air quality control systems operate independently of each other and frequently result in temporally correlated energy demand surges. As peak power prices are 200-400 times that of the nominal rate, this uncoordinated activity is both expensive and operationally inefficient. While several approaches for load shifting and model predictive control have been proposed, we present an alternative approach to fine-grained coordination of energy demand by scheduling energy consuming control systems within a constrained peak power while ensuring custom climate environments are facilitated. This project includes scheduling of energy control systems, sensing-based reduced order modeling of buildings and tools for integrated modeling and controls for energy-efficient buildings.
Biography: Rahul Mangharam is the Stephen J Angello Chair and Assistant Professor in the Dept. of Electrical & Systems Engineering and Dept. of Computer & Information Science at the University of Pennsylvania. He directs the Real-Time and Embedded Systems Lab at Penn. His interests are in real-time scheduling algorithms for networked embedded systems with applications in automotive systems, medical devices and industrial control networks.
He received his Ph.D. in Electrical & Computer Engineering from Carnegie Mellon University where he also received his MS and BS in 2007, 2002 and 2000 respectively. In 2002, he was a member of technical staff in the Ultra-Wide Band Wireless Group at Intel Labs. He was an international scholar in the Wireless Systems Group at IMEC, Belgium in 2003. He has worked on ASIC chip design at Marconi Communications (1999) and Gigabit Ethernet at Apple Computer Inc. (2000). Rahul received the 2013 NSF CAREER Award, 2012 Intel Early Faculty Career Award and was selected by the National Academy of Engineering for the 2012 US Frontiers of Engineering.

The Slow-down of Moore's Law and the Future of Supercomputing
Mon, Sep 16, 2013 @ 03:30 PM - 05:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Marc Snir, Argonne National Laboratory & University of Illinois at Urbana-Champaign
Talk Title: The Slow-down of Moore's Law and the Future of Supercomputing
Abstract: Supercomputing has had two "easy" decades where most of the increased performance of supercomputers came from the increase in uniprocessor performance. This period has come to an end, due to the stagnation in uniprocessor performance. The slow-down of Moore's Law implies that future performance improvements will require more innovation at the architecture level and the software layers. The talk will discuss the evidence for a slow-down; the implications for supercomputing; and the potential research directions this suggests.
Biography: Marc Snir is director of the Mathematics and Computer Science Division at Argonne National Laboratory and Michael Faiman and Saburo Muroga Professor in the Department of Computer Science at the University of Illinois at Urbana-Champaign. He received a PhD in mathematics from the Hebrew University of Jerusalem in 1979 and spent two years at New York University, where he was involved with the NYU Ultracomputer project.
At IBM Research, during 1990-2000, he led the research team that developed the software for the IBM Scalable Parallel System (IBM SP) product - the first microprocessor-based highly parallel system that was commercialized by IBM. Snir also led the research group responsible for major contributions to the IBM Blue Gene system. During this period, Snir was involved in the standardization efforts on High-Performance Fortran and MPI. Snir served as head of the Dept. of Computer Science at UIUC from 2001 to 2007, and was lead software architect for the Blue Waters system installed at NCSA. Snir has published numerous papers and given many presentations on computational complexity, parallel algorithms, parallel architectures, interconnection networks, parallel programming environments, and parallel languages and libraries.
Snir is a fellow of the AAAS, the ACM, and the IEEE. He has Erd-s number 2 and is a mathematical descendant of Jacques Salomon Hadamard.

Full Speed MRI
Tue, Sep 17, 2013 @ 10:00 AM - 11:00 AM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. James Pipe, Barrow Neurological Institue, Phoenix, AZ
Talk Title: Full Speed MRI
Series: Medical Imaging Seminar Series
Abstract: The cost of clinical MR scans worldwide is estimated to be 10's of billions of dollars each year, in part because of the length of MR exams. While the duration of each MR scan varies widely across countries and even within the US, current clinical MRI scans take perhaps 30-45 minutes, of which perhaps 50% is used for actual scanning. Much of this scanning is done using methods which, despite their inefficiencies, are used due to their robustness. Our lab is attempting to create a high-quality neuro exam (same number of scans, same contrast, with high SNR and high resolution) in 5 minutes of total scan time, with a goal of achieving 10 minute exam times.
Biography: > Dr. Pipe received his PhD in bioengineering from the University of Michigan in 1993. After serving on the faculty of the Department of Radiology at Wayne State University, he joined Barrow Neurological Institute in 1999, where he now serves as the Director of Neuroimaging Research. He is a Fellow of the International Society for Magnetic Resonance in Medicine (ISMRM), and served on the ISMRM Board of Trustees and chaired their 20th Annual meeting in Melbourne, Australia in 2012. He is also currently the vice president-elect for ISMRM.
>
> Dr. Pipe's research focuses on developing next-generation methods for magnetic resonance imaging (MRI) that have a significant, positive impact on patient care. He invented the first commercial method for MRI specifically designed to eliminate the blurring of images caused by patients moving their head during an MRI scan. This method is now sold on almost all commercial scanners. He also works on methods to improve imaging of brain structures, function, and connectivity as well as on methods for measuring blood flow. He continues to help establish the mathematical underpinnings of innovative MRI techniques intended to reduce scan times while increasing the information available to physicians.

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Prof. Amir Mortazawi, University of Michigan
Talk Title: Frequency Agile Circuits Based on Thin Film Ferroelectrics
Series: Integrated Systems Seminar Series
Abstract: My talk is on the design of frequency agile circuits based on thin film ferroelectrics. Central to this work is the use of thin film barium strontium titanate (BST), a low loss, high dielectric constant field dependent material. The electric field dependence of BST is used to design tunable RF and microwave devices and components. Other applications such as linearization of power amplifiers will also be discussed. Another important characteristic of BST is its dc electric field induced piezoelectric and electrostrictive effects. These properties can be utilized to design intrinsically switchable film bulk acoustic wave resonators (FBARs) and FBAR filters. Ferroelectric based filter banks can make it possible to reduce size and power consumption of conventional filter banks employed in multi-standard and frequency agile radios. Recent results for intrinsically switchable BST bulk acoustic wave resonators and filters will be presented.
Biography: Amir Mortazawi received the Ph.D. degree in electrical engineering from The University of Texas at Austin, in 1990.
He is a currently a Professor of electrical engineering with The University of Michigan at Ann Arbor. His research interests include millimeter-wave circuits, phased arrays, power amplifiers, ferroelectric thin film based devices and frequency-agile microwave circuits.
Mortazawi was the Editor-in-Chief of the IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES from 2006-2010. He is a member of the IEEE Microwave Theory and Techniques Society (IEEE MTT-S) Administrative Committee (AdCom). He also served as Associate Editor for the IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION (1998â2001), IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES (2005). Mortazawi is a Fellow of IEEE.

Integer-Forcing for Channels, Sources and ADCs
Mon, Sep 23, 2013 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Or Ordentlich, Tel Aviv University
Talk Title: Integer-Forcing for Channels, Sources and ADCs
Abstract: Integer-Forcing (IF) is a new framework, based on compute-and-forward, for decoding multiple integer linear combinations from the output of a Gaussian multiple-input multiple-output (MIMO) or multiple-access (MAC) channel. Integer-forcing is applicable when all transmitters use nested linear/lattice codes.
Building on the IF framework, we derive new theoretical results and develop new low-complexity coding schemes for several problems.
We begin by studying the capacity region of the Gaussian MAC under the constraint that all users transmit from a chain of nested lattice codes. Interestingly, the obtained rate-region depends on number-theoretic properties of the channel gains. Then, we apply these results in conjunction with lattice interference alignment to approximate the sum capacity of the symmetric K-user Gaussian interference channel.
We next apply the IF approach to arrive at a new low-complexity scheme, IF source coding, for distributed lossy compression of correlated Gaussian sources under an MSE distortion measure. The performance of the proposed scheme closely follows Berger-Tung's inner bound. Moreover, a one-shot version of IF source coding is described and analyzed. We argue that this scheme is simple enough to potentially lead to a new design principle for analog-to-digital converters (ADCs) that can exploit spatial correlations between the sampled signals.
Biography: Or Ordentlich received the B.Sc. degree (cum laude) and the M.Sc. degree (summa cum laude) in 2010 and 2011, respectively, in electrical engineering from Tel Aviv University, Israel. He is currently working toward the Ph.D. degree at Tel Aviv University.
Or is the recipient the Adams Fellowship awarded by the Israel Academy of Sciences and Humanities, the Advanced Communication Center (ACC) Feder Family award for outstanding research work in the field of communication technologies (2011), and the Weinstein Prize for research in signal processing (2011,2013).

Speaker: Dr. Oren Eliezer, CTO, Xtendwave
Talk Title: Designing RF Transceivers to be Manufacturable at Low Cost & The New Enhanced "Atomic Clock" WWVB Broadcast and Fully-Digital Multi-Mode Receivers for it.
Series: Integrated Systems Seminar Series
Abstract: Mobile devices are based on highly integrated transceiver system-on-chip (SoC) ICs, where the RF circuitry, additional analog functions, and a considerable amount of digital logic (including a processor and memory), all share the same CMOS die. Furthermore, they often include more than one radio, such as GPS, WLAN, Bluetooth and FM, thereby further increasing the potential for self-interference and necessitating careful design practices to allow satisfactory coexistence of all functions on the SoC. This seminar presents approaches for design-for-manufacturability (DfM) that lead to timely and profitable results in the design of consumer-market transceiver SoCs in advanced CMOS processes.
The National Institute for Standards and Technology (NIST) has been broadcasting the date and time from their accurate atomic source for many decades using a simple amplitude/pulse-width modulation scheme. In October 2012 an enhanced broadcasting system, designed by Xtendwave under a government grant, was introduced at the station, demonstrating several orders of magnitude of improvement in link margin. This seminar presents many interesting challenges associated with this modernized digital communications system, as well as novel radio architecture and antenna ideas that are being developed for it at Xtendwave. The seminar will include a real-time reception demonstration of the receiver CMOS IC designed by Xtendwave, which exhibits a 140dB dynamic range, the widest in consumer-market receiver ICs.
Biography: Dr. Oren Eliezer received his BSEE and MSEE degrees in Electrical Engineering from the Tel-Aviv University in Israel in 1988 and 1996 respectively, and his PhD from the University of Texas at Dallas (UTD) in 2008. He served in The Israel Defense Forces from 1988 to 1994, where he specialized in wireless communications. After his military service he cofounded Butterfly Communications in Israel and served as the company’s chief engineer.
