Talk Title: Recent Advances in Electric Machines and Power Electronics for Renewable Energy - Offshore Electric Power Grid
Abstract: Power electronics is an innovative and expanding area in electrical engineering. Recent advances in high-power devices permit the control and flow of electric energy efficiently. The digital nature of power switching devices makes the control of electric power switching circuits convenient with the use of digital signal processors. Power electronics has widespread applications in today’s industries, such as in power supplies, variable speed drives, automotive, marine, etc. Implementation of adjustable speed motor drives in high impact automotive, aerospace, and electric energy applications requires a new generation of design and control strategies known as “fault tolerant design”. In fact, fault tolerance and durability play a central role in the design and development of advanced power electronic systems in such applications. This in turn calls for a modular configuration in respective magnetic and electronic architectures of modern power systems. Our progress on the design of various electric machines and power electronic converters for a variety of applications such as wave and solar energies, hybrid electric vehicles, flywheel energy storage systems, appliances etc. will be briefly presented. More specifically, our recent development on offshore power electronic system will be discussed.

Talk Title: “Mid-Infrared Quantum Cascade Lasers”
Abstract: Quantum Cascade (QC) lasers are a rapidly evolving mid-infrared and THz, semiconductor laser technology based on intersubband transitions in multiple coupled quantum wells. The lasers’ strengths are their wavelength tailorability, high performance and fascinating design potential. We will first give a brief introduction into QC lasers followed by a discussion of several recent highlights, such as the quest for high performance QC lasers, especially high efficiency and single-mode operation, and the implementation of unconventional laser schemes. We will also discuss several applications, such as field campaigns of QC laser-based sensing, and our recent work in non-invasive glucose sensing. As an example for high-performance QC lasers, we examine lasers around 5 mm wavelength. First, we focus on thorough engineering of conventional QC lasers. The quest for high power and high efficiency QC lasers requires these lasers to have a low intrinsic threshold, a high characteristic temperature, a low voltage defect, and superior heat sinking. Next, we move on to unconventional designs, and a recent innovation in how the carrier injection into QC laser active regions is described; ultra-strong coupling between injectors and active regions are required, and the importance of interface roughness scattering is documented. The resultant QC lasers are nearly 50% power efficient at cryogenic temperatures. With respect to spectral innovations, a spectrally broadband QC laser based on a âcontinuum-to-continuum’ design will be presented, which differs from conventional, artificially spectrally broadened QC lasers in that almost no trade-off needs to be made between gain-bandwidth and laser performance with respect to laser threshold and output power. When this laser is put into an external cavity, a wide, continuous single-mode tuning range of well over 400 cm-1 is achieved. Next we explore opportunities for obtaining single-mode and tunable emission without the need of dispersive gratings, such as external dispersive cavities or gratings etched into the lasers. Folded cavities, “candy-cane“-shaped lasers, and Asymmetric Mach Zehnder cavities have all shown great potential for achieving single-mode emission at reduced fabrication complexity and cost. A recent example for the versatility of QC laser design is the development of QC lasers with two optical transitions in each active region instead of the usually just single photon emission. These lasers have potential for higher power efficiency and better performance especially at the long wavelength regime of l > 12 mm. Finally, we provide a quick overview on QC laser applications and show scattering of mid-infrared light from tissue components deeper in the skin potentially for non-invasive glucose sensing. The work presented is mostly supported by MIRTHE (NSF-ERC) with smaller contributions from other sources; the work has been conducted in collaboration with many valued colleagues in our own research group and across MIRTHE.

Speaker: Saima Aman, USC Viterbi PhD Student, Computer Science
Talk Title: Data-driven Models for Dynamic Demand Response
Series: EE598 Seminar Course
Abstract: Smart Grid is the extension of the traditional electric grid with advanced technologies for communication, monitoring and control. Its goal is to gain reliability and efficiency in generation, distribution, and consumption, and ultimately achieve energy sustainability. Demand response (DR) is a key component of Smart Grid that deals with the customers reducing their electricity consumption during peak load periods when asked by the utility. The next challenge in DR research is to achieve dynamic demand response (D2R) which deals with dynamic decision making about when, by how much, and how to reduce electricity use by the consumers in response to dynamically changing conditions of generation and consumption. In Smart Grid, fine grained and rich variety of spatio-temporal data is available which can be leveraged to build data-driven models to aid decision making for D2R.
Biography: Saima Aman is a Ph.D. student in Computer Science and Research Assistant at the Center for Energy Informatics, University of Southern California, Los Angeles. Her current research is focused on applying data analytics to the problem of dynamic demand response in smart grids, including both direct building controls and voluntary curtailment by consumers, to achieve reliable and efficient grid operations. She received her M.S. in Computer Science from the University of Ottawa, Canada, and B.Tech. in Computer Engineering from AMU, India. She is a member of IEEE and AAAI.

Talk Title: The Dynamics of the Unconscious Brain Under General Anesthesia
Abstract: General anesthesia is a drug-induced, reversible condition comprised of five behavioral states: unconsciousness, loss of memory, loss of pain sensation, akinesia, and hemodynamic stability with control of the stress response. The mechanisms by which anesthetic drugs induce the state of general anesthesia are considered one of the biggest mysteries of modern medicine. We use three experimental paradigms to study general anesthesia-induced loss of consciousness in humans: combined fMRI/EEG recordings, high-density EEG recordings and intracranial recordings. These studies are allowing us to establish precise neurophysiological, neuroanatomical and behavioral correlates of unconsciousness under general anesthesia. Combined with our mathematical modeling work on how anesthetics act on neural circuits to produce the state of general anesthesia we offer specific hypotheses as to how changes in level of activity in specific circuits lead to the unconscious state. Our findings suggest that the state of general anesthesia is not as mysterious as currently believed.
Biography: Emery N. Brown is professor of computational neuroscience and health sciences and technology at MIT, the Warren M. Zapol Professor of Anesthesia at Harvard Medical School, and a practicing anesthesiologist at Massachusetts General Hospital. Dr. Brown received his B.A. from Harvard College (magna cum laude), his M.A. and Ph.D. in statistics from Harvard University and his M.D. (magna cum laude) from Harvard Medical School. Dr. Brown’s methodology research develops signal processing and statistical methods to characterize how neurons in the brain represent and transmit information. His experimental research is characterizing the neurophysiology of how anesthetics act in the brain to create the state of general anesthesia. Dr. Brown is a fellow of the IEEE and of the American Academy of Arts and Sciences, a member of the Institute of Medicine, a 2007 recipient of an NIH Director,s Pioneer Award and a 2012 recipient of an NIH Director’s Transformative Research Award.

Speaker: Prof. Alyosha Molnar , Cornell University
Talk Title: Light-field Imaging Using Angle-Sensitive Pixels in Standard CMOS
Abstract: Whereas traditional photography techniques maps the intensity of light at a particular plane, Light-field imaging attempts to capture a more complete description of the field of light rays. In particular, by mapping the distribution of incident angle in a scene, Light-field imaging permits passive extraction of 3-D structure. I will present a new type of CMOS pixel, the “angle-sensitive pixel” (ASP), based on the Talbot effect. ASPs use stacked diffraction gratings built from CMOS interconnect layers to generate a strongly angle-sensitive light response. An appropriately chosen mosaic of ASPs, then, provides a much richer description of incoming light from out-of-focus scenes, and does so in a computationally compact format, similar to the Gabor filters used in many image-processing applications. I will discuss several applications for arrays of ASPs, including digital light-field photography, lensless far-field imaging, and near-field lensless 3-D imaging of microscale samples.
Biography: Prof. Alyosha Molnar received his BS from Swarthmore College in 1997, and after spending a season as a deck-hand on a commercial Tuna fishing boat, worked for Conexant Systems for 3 years as an RFIC design engineer. He was co-responsible engineer developing their first-generation direct-conversion receiver for the GSM cellular standard. That chip, and subsequent variants, have sold in excess of 100 million parts. When he entered graduate school at U.C. Berkeley in 2001, Molnar worked on an early, ultra-low-power radio transceiver for wireless sensor networks (receiving his master’s degree), and then joined a retinal neurophysiology group where he worked on dissecting the structure and function of neural circuits in the mammalian retina. He joined the Faculty at Cornell University in 2007, and presently works on low-power software-defined radios, neural interface circuits, and new integrated imaging techniques.

Talk Title: Behavioural Modeling & Linearization of RF Power Amplifiers
Abstract: In cellular wireless communications systems, the RF power amplifier (PA) in the transmitter must be as efficient as possible, to minimize energy costs, to prolong battery life, and for âgreen’ considerations. Modern spectrally-efficient, digitally-modulated signals such as LTE and UMTS present a challenge for efficient RF PA design, and the power amplifier architectures that are adopted to achieve this goal are generally very nonlinear, and so some form of linearization technique is necessary.
The increasing use of linearization techniques, and especially the emergence of high speed digital processing as an enabling technology to implement digital pre-distortion (DPD) of the PA input signal, represent an important paradigm shift in PA design. The PA component can now be designed with more emphasis on power and efficiency, without the traditional constraints of meeting stringent linearity specs simultaneously. Understanding the utility of a linearizer to obtain optimum efficiency has thus become a new subject area in modern RF PA design.
The system-level design of linearized PA transmitters requires accurate models to achieve the optimal performance. Behavioural modeling is used to describe the PA and linearizer at this level of the design. In this tutorial, we shall present some approaches to the behavioral modeling of nonlinear dynamical systems that can be used to model RF PAs; particular emphasis will be given to the treatment of memory effects. Some common mathematical and systematic approaches to model generation will be presented, to obtain accurate but compact nonlinear dynamical models. A brief description of some characterization techniques will be included. These same nonlinear modeling techniques can be applied to the design of successful pre-distortion algorithms. We shall illustrate the overall structure of a linearized transmitter using several DPD architectures, and we shall present various approaches to adaptive pre-distortion, considering such features as convergence, signal bandwidth, accuracy, and cost.

Talk Title: Adaptive Sensing for Resource Management in Distributed Sensor Networks
Series: EE598 Seminar Course
Abstract: Energy conservation is an important issue in embedded sensor networks since large batteries are not practical in many real-world scenarios. The issue becomes even more critical in distributed sensor networks connected with wireless links due to the high energy cost of radio communication. In this talk, I will present the use of Markov Decision Processes (MDP) as a framework for coordinated sensing and adaptive communication between distributed sensors. The technique enables distributed sensors to adapt their sampling rates in response to changing event criticality and the availability of resources (energy) at each sensor node. The technique was developed as part of a body sensor network project at the Childrenââ¬â¢s Hospital Los Angeles for continuous mobile human health monitoring. Similar adaptive sensing methods were also applied to other distributed sensing applications such as a coastal ocean monitoring system.
Biography: Anand Panangadan is a Senior Research Associate working with Prof. Viktor Prasanna at USC Viterbi School of Engineering. Prior to this appointment, he was a Post-doctoral Affiliate at the NASA Jet Propulsion Laboratory (JPL) and a Research Specialist at the Saban Research Institute of the Childrenââ¬â¢s Hospital Los Angeles.
