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.

Assane Gueye: Quantifying Network Vulnerability to Attacks: A Game Theoretic Approach

Speaker: Assane Gueye, National Institute of Standards and Technology (NIST)
Talk Title: Quantifying Network Vulnerability to Attacks: A Game Theoretic Approach
Series: CS Colloquium
Abstract: Designing network topologies that are robust and resilient to attacks has been and continues to be an important and challenging topic in the area of communication networks. One of the main difficulties resides in quantifying the robustness of a network in the presence of an intelligent attacker who might exploit the structure of the network topology to design harmful attacks. To capture the strategic nature of the interactions between a defender and an adversary, game theoretic models have been gaining a lot of interest in the study of the security of communication networks. In a recent line of research, network blocking games have been introduced and applied to the analysis of the robustness of network topologies. A network blocking game takes as input the communication model and the topology of a network and models the strategic interactions between an adversary and the network operator as a two-player game. The Nash equilibrium strategies are then used to predict the most likely attacker's actions and the attacker's Nash equilibrium payoff serves as a quantification of the vulnerability of the network.
In this talk, I will present the notion of network blocking games and show how they can be used to derive network vulnerability metrics by using a series of examples of communication models. I will also show how these metrics can be used to design networks that are robust against attacks and/or strengthen the robustness of existing networks. I will also show how the metrics can be used to identify the most critical links in a network.

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.

Talk Title: "Evidence Based Discovery Research with Electronic Medical Records"
Series: Epstein Institute Seminar Series
Abstract: One major component of modern evidence-based medicine is the use of patientsââ¬â¢ ââ¬Åbaselineââ¬Â information for personalized treatment selection and disease management. For instance, the benefit of giving chemotherapy prior to hormone therapy with tamoxifen for postmenopausal women with lymph node- breast cancer may vary depending on the estrogen receptor (ER) status of the tumor. ER- patients benefit substantially from chemotherapy while ER+ patients do not benefit as compared to receiving tamoxifen alone. Developing individualized decision rules for disease management can be extremely useful in practice.
To realize the goals of personalized medicine, significant efforts have been made on building risk prediction models and assessing subgroup-specific treatment effects or predictiveness of a new marker via traditional clinical trials or observational studies. In this talk, I will give a brief introduction on how one may construct virtual cohorts from the electronic medical records to conduct subsequent studies on personalized medicine. I will also discuss some of the recent statistical methods that can potentially be used to address questions arising from the field of personalized medicine.

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.

CS Colloquium: Katrina Ligett

Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Katrina Ligett, Caltech
Talk Title: CS Colloquium: Katrina Ligett
Series: CS Colloquium
Abstract: In this talk, we consider the problem of estimating a potentially
sensitive (individually stigmatizing) statistic on a population. In our model, individuals are concerned about their privacy, and
experience some cost as a function of their privacy loss.
Nevertheless, they would be willing to participate in the survey if they were compensated for their privacy cost. These cost functions are not publicly known, however, nor do we make Bayesian assumptions about their form or distribution. Individuals are rational and will misreport their costs for privacy if doing so is in their best interest. Ghosh and Roth recently showed in this setting, when costs for privacy loss may be correlated with private types, if individuals value differential privacy, no individually rational direct revelation mechanism can compute any non-trivial estimate of the population statistic. In this paper, we circumvent this impossibility result by proposing a modified notion of how individuals experience cost as a function of their privacy loss, and by giving a mechanism which does not operate by direct revelation. Instead, our mechanism has the ability to randomly approach individuals from a population and offer them a take-it-or-leave-it offer. This is intended to model the abilities of a surveyor who may stand on a street corner and approach passers-by.
Joint work with Aaron Roth.

Talk Title: Studies Into Vibration-Signature-Based Methods for System Identification, Damage Detection and Health Monitoring of Civil Infrastructures
Abstract:
Civil infrastructures play a vital role in human societies. Recent catastrophic events due to the deficiency, failure or malfunction of these systems, claiming many lives and resulting in substantial economic loss, have attracted extensive attention focused on reviewing and amending the design and maintenance procedures of civil infrastructures. In addition to the possible failure of structural components, long-term forms of damage due to deterioration or fatigue may also necessitate regular monitoring of civil structures. Therefore, depending on the importance, use and risk, the structure of interest needs to be equipped with inspection, monitoring and maintenance systems. Structural Health Monitoring (SHM) is generally associated with any engineering methodology whose aim is to detect, locate and quantify the damage in the target system. Vibration-based techniques, as the most conventional SHM approaches, acquire and analyze the structural response using a variety of sensors mounted at different locations on the structure. The main goal of the study reported herein is to investigate and compare different vibration-signature-based methods for system identification, damage detection and health monitoring of civil structures. Various well-known techniques such as finite element model updating approach and damage detection methods based on artificial neural networks are studied and evaluated. Experimental data from two case studies, a quarter-scale two-span bridge system, tested at the University of Nevada, Reno, and a 1/20 scale 4-story building equipped with smart devices of magneto-rheological (MR) damper, are used for investigation and validation purposes. Guidelines are established for the optimum selection of the dominant control parameters involved in the application of some of the robust SHM approaches for achieving reliable SHM results under realistic conditions.

Abstract
Keyword search is a prominent data retrieval method for the Web, largely because the simple and efficient nature of keyword processing allows a large amount of information to be searched with fast response. However, keyword search approaches do not formally capture the clear meaning of a keyword query and fail to address the semantic relationships between keywords. As a result, the accuracy (precision and recall rate) is often unsatisfactory, and the ranking algorithms fail to properly reflect the semantic relevance of keywords.
Our research particularly focuses on increasing the accuracy of search results for multi-word search. We propose a statistical ontology-based semantic ranking algorithm based on sentence units, and a new type of query interface including wildcards. First, we allocate higher-ranking scores to keywords located in the same sentence compared with keywords located in separate sentences. While existing statistical search algorithms such as N-gram only consider sequences of adjacent keywords, our approach is able to calculate sequences of non-adjacent keywords as well as adjacent keywords.
Second, we propose a slightly different type of query interface, which considers a wildcard as an independent unit of a search query - to reflect what users are actually seeking by way of the function of query prediction based on not query data but actual Web data. Unlike current information retrieval approaches such as proximity, statistical language modeling, query prediction and query answering, our statistical ontology-based model synthesizes proximity concept and statistical approaches into a form of ontology. This ontology helps to improve web information retrieval accuracy.
We validated our methodology with a suite of experiments using the Text Retrieval Conference document collection. We focused on two-word queries in our experiments - as two-word queries are quite common. After applying our statistical ontology-based algorithm to the Nutch search engine, we compared the results with results of the original Nutch search and Google Desktop Search. The result demonstrates that our methodology has improved accuracy quite significantly.

Talk Title: "Space Colonies Now! via Commerce, Robotics, and Systems Engineering"
Series: Epstein Institute Seminar Series
Abstract: A revolution is now underway as humanity transitions from being a single planet species to a solar system species. This has been set in motion by the explosion of technologies over the 40 years since the early Moon landings of the Apollo program. Some of the key technology areas include: rocketry, robotics, additive manufacturing, chemical processing, solar power, and artificial intelligence, to name just a few. Unlike prior migrations of humanity across the continents and oceans of Earth, the first wave of space migration will be done through robotic telepresence because we are going to places that are hostile to our bodies. The continents here on Earth had been transformed before our arrival by lifeââ¬â¢s activity across billions of years, converting the barren rocks and sunlight into topsoil with vibrant ecospheres where we can live. The new generation of space telepioneers, on the other hand, will have to do that job themselves. They will do it through robotic space mining, chemical processing, and in-space manufacturing, setting up autonomous industries and converting the barren rocks and sunlight into vibrant environments where we can live. The basic technologies to do this already exist, and telepioneering the incomprehensibly vast resources of our solar system holds so much economic potential that it can be a surprisingly short time before the first biological colonists actually live beyond Earth. You might see it in your lifetime. However, the complexity of the engineering systems required to transform the solar system so quickly will require the most advanced application of systems engineering humans have ever known. The growing list of commercial space companies whose business plan it is to do this profitably is a good indicator that the time is now!

Abstract: The formation of nanoparticles (nucleation) in gas phase environments is of critical importance in a number of systems, including the ambient atmosphere and modern combustion engines. Unfortunately, prediction of nucleation rates is often not possible, with measured nanoparticle formation and growth rates differing from classical theoretical predictions by several orders of magnitude. In any environment, the rate of nucleation is defined as the net difference between the rate at which vapor molecules collide with and stick to growing nanoscale clusters (association) and the rate at which vapor molecules evaporate (dissociate) from such clusters. Therefore, to improve nucleation rate predictions, detailed study of association and dissociation reactions are necessary. In this talk, two new measurement systems used to examine nanoparticle-vapor molecule association and dissociation will be discussed. The first of these systems consists of a high resolution differential mobility analyzer (DMA) and time-of-flight mass spectrometer (MS), which enables in-series measurement of the collision cross sections and masses of 1-2 nm nanoparticles. Collision cross section measurements are made at atmospheric pressure, controlled vapor molecule (water vapor in the presented cases) concentrations, and controlled temperature. Shifts in the average collision cross section of mass-identified entities can yield the equilibrium binding coefficients of vapor molecules, as well as the Gibbs free energy change, enthalpy change, and entropy change brought about by vapor molecule sorption. The second presented system consists of two DMAs operated in series with a controlled temperature furnace connecting the DMAs. This system is used to examine single atom dissociation from 2-5 nm silver nanoparticles.

Chemical Loop Technology and CO2 Capture

Talk Title: Chemical Looping Technology and CO2 Capture
Series: Lyman L. Handy Colloquium Series
Abstract: The concept of chemical looping reactions has been widely applied in chemical industries, e.g., the production of hydrogen peroxide (H2O2) from hydrogen and oxygen using 9,10-anthraquinone as the looping intermediate. Fundamental research on chemical looping reactions has also been applied to energy systems, e.g., the splitting of water (H2O) to produce oxygen and hydrogen using ZnO as the looping intermediate. Fossil fuel chemical looping applications had been used commercially with the steam-iron process for coal from the 1900s to the1940s and had been demonstrated at a pilot scale with the carbon dioxide acceptor process in the 1960s and 1970s. There are presently no chemical looping processes using fossil fuels in commercial operation. A key factor that hampered the continued use of these earlier processes for fossil energy operation was the inadequacy of the reactivity and recycleability of the looping particles. This factor led to higher product costs for using the chemical looping processes, compared to the other processes that were petroleum or natural gas based. With CO2 emission control now being considered as a requirement, interest in chemical looping technology has resurfaced. In particular, chemical looping processes are appealing due to their unique ability to generate a sequestration-ready CO2 stream while yielding high energy conversion efficiency. Renewed fundamental and applied research since the early 1980s has emphasized improvement over the earlier shortcomings. New techniques have been developed for direct processing of coal or other solid carbonaceous feedstock in chemical looping reactors. Significant progress is underway in particle design, reactor development, and looping system integration, as demonstrated by the operation of several pilot or sub-pilot scale units worldwide, making it possible that chemical looping technology may be commercially viable in the future for processing carbonaceous fuels.
This presentation will describe the fundamental and applied aspects of modern chemical looping technology that utilizes fossil and biomass as feedstock. The presentation will discuss reaction engineering and solids flow issues associated with this technology. Specifically, it will highlight reactions, reactors and solids-gas issues associated with the optimum feedstock conversion and relationship among the metal oxide conversion, solids flux and reactor configurations. Opportunities and challenges for chemical looping process scale-up and commercialization will also be illustrated.

Talk Title: Stretching of Lipid Membranes Using Optical Forces
Abstract: Membrane bending and stretching control key aspects of cellular function, and changes in chemical composition alter membrane mechanical properties. GUVs are model lipid bilayer systems that have become popular for investigating membrane mechanical properties. The ability of membranes to bend under low stress is characterized by the bending modulus (úB). We show that the optical stretcher, or dual-beam optical trap (DBOT), provides a method for non-invasive application of time-dependent forces on a GUV, allowing rapid measurement of the bending modulus.The applied stress in a DBOT elongates the GUV, increasing its eccentricity. We increase the optical power in the DBOT as a function of time and extract the resulting surface area strain (percent change in surface area) from analysis of microscope video images. The lateral tension on the membrane at each power level is calculated from the surface stress. The bending modulus can be extracted from the slope of the area strain vs. surface stress plot.We compare the bending modulus values obtained from a lipid bilayer in liquid phase, 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC), and bilayer in gel phase, 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC). We observe that the bending modulus of gel phase bilayer is larger than the lipid phase bilayer. We then show that we can use our high-throughput setup to measure the bending modulus of populations of GUVs and obtain ensemble statistics. We compare the bending modulus of POPC lipid bilayer with and without cholesterol and show that the addition of cholesterol does not significantly affect the bending modulus.

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: Towards water and energy sustainability with innovative membrane processes and systems
Abstract: Fresh water scarcity is forcing water providers to rely on alternative water supply sources such as saline waters (e.g., seawater) and ââ¬Åwasteââ¬Â waters. Low-energy treatment processes are desired to remove both established and emerging contaminants from these process waters. Forward osmosis (FO) and membrane distillation (MD) have gained national and international attention as viable, economic alternatives for seawater desalination and wastewater reclamation. Pressure-retarded osmosis (PRO) in combination with RO is also being considered to achieve water desalination at low energy expenditure.
FO is an osmotically driven membrane separation process that can be used as a high-level pretreatment for RO or other desalination process. The FO membrane provides an economical means to pretreat process waters and protect the RO membrane from excessive fouling. The FO-followed-by-RO scheme also represents a dual osmotic barrier that may be particularly useful for the removal of micropollutants. MD is a thermally driven membrane separation process that has long been investigated in small-scale laboratory studies and has the potential to become a viable tool for water desalination and brine concentration. Compared to conventional distillation methods, MD requires only small temperature differences â⬓ temperature differences achievable through the use of low-grade or waste heat sources. Compared to RO, the driving force in MD is not reduced by osmotic pressure and thus, MD can be used to treat high salinity solutions or to provide enhanced recovery through brine desalination. Results from investigations on the energy, recovery, and water quality advantages of FO and MD over conventional methods will be presented. The state-of-the-art of research and development of FO and MD systems will also be discussed.
In PRO, water from a low salinity solution permeates through a membrane into a pressurized, high salinity solution; power is obtained by depressurizing the permeate through a hydroturbine. A synergistic RO-PRO desalination system was designed to reduce RO energy requirements and to dilute the brine generated by the RO process prior to disposal. The development and testing of this system will be presented.

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.

Abstract:
New applications of computing are being enabled by instrumentation of physical entities, aggregation of data, and the analysis of the data. The resulting integration of information and control permits efficient and effective management of complex man-made systems. ExamplesÃÂ include transportation systems, buildings, electrical grids, health care systems, governments,ÃÂ and supply chains. Achieving this vision requires extensive data integration and analysis, overÃÂ diverse, rapidly changing, and often uncertain data.

Speaker: Larry G. Redekopp, Professor in the Department of Aerospace & Mechanical Engineering at the University of Southern California
Talk Title: Modeling the Internal Weather in Lakes
Abstract: This lecture will address issues pertaining to the modeling of the internal (subsurface) weather in enclosed, or semi-enclosed, basins under mid-summer conditions. An understanding of, and an ability to predict, the internal dynamics of stratified lakes is central to the management of many water resources, particularly the quality of potable and recreational resources. The internal bio-geochemical quality of a lake depends crucially on the hydrodynamic processes whereby energy input at the basin scale via solar insolation and surface wind stresses is transferred down to mixing and dissipation scales. It is important to build tools that model the internal weather in closed basins with reasonable fidelity for purposes of both gaining a general qualitative understanding of lake hydrodynamics and for providing quantitative estimates of space-time scales for energy transfer routes and particulate transport paths.
The lecture will address several 'rapid-simulation' models relevant to small and moderate sized, stratified lakes in which an evolving, energetic, internal wave field is excited by surface wind events. Models of the degeneration of the wind-driven, basin-scale, internal seiche into a field of bi-directional, propagating internal waves for several lake configurations will be discussed, including the role of the evolving internal wave field in both the stimulation of benthic boundary eruptions and the dispersion of toxic spills in a moderately-sized lake.

EE 598: ELECTRICAL ENGINEERING RESEARCH SEMINAR COURSE #3
Thu, Jan 31, 2013 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Anand Panangadan, PhD, Senior Research Associate, Electrical Engineering, USC Viterbi School of Engineering
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. His research interests are in artificial intelligence and machine learning, and in the application of techniques from these fields to the autonomous control of networked sensors. He received his Ph.D. in Computer Science from the University of California Los Angeles and the B.Tech. degree in Computer science and Engineering from the Indian Institute of Technology, Bombay.
