  • Upper Airway Dynamic Imaging During Awake and Asleep Tidal Breathing

    Wed, Oct 25, 2017 @ 01:30 AM - 02:30 PM

    Ming Hsieh Department of Electrical Engineering

    Conferences, Lectures, & Seminars


    Speaker: Chantal Darquenne, PhD, Professor, Dept. of Medicine University of California, San Diego

    Talk Title: Upper Airway Dynamic Imaging During Awake and Asleep Tidal Breathing

    Series: Medical Imaging Seminar Series

    Abstract: Obstructive sleep apnea (OSA) is characterized by recurrent partial or complete airway closure during sleep, and has important clinical implications ranging from disruption of sleep with daytime sequelae of excessive sleepiness and poor quality of life to adverse cardiovascular or metabolic outcomes. While polysomnography and studies based on measurements of airway pressures and resistance have provided a wealth of information on upper airway physiology, they are unable to assess the three- dimensional anatomy of the upper airway and its conformational changes during breathing. Knowledge of the morphology and mechanical behavior of this structure is essential for a more complete understanding of the occurrence of upper airway obstruction. Such information can be obtained with imaging technology and will be the focus of this seminar.Data will be presented from a group of OSA subjects and a group of age- and BMI-matched healthy controls that underwent MR imaging to assess upper airway morphometry and changes in airway size during tidal breathing. Data were collected both during wakefulness and natural sleep with simultaneous measurement of nasal-oral flow partition and sleep state and stages. Results show significant differences in the magnitude of the changes in upper airway size over a tidal breath between OSA subjects and controls both during wakefulness and natural sleep suggesting that, for tidal breathing conditions, dynamic OSA imaging during wakefulness is representative of behavior during sleep.

    Biography: Chantal Darquenne is a Professor of Medicine at the University of California, San Diego (UCSD) and the President-elect of the International Society for Aerosols in Medicine. She earned her Ph.D. degree in Applied Sciences from the Universit├ę Libre de Bruxelles (Belgium) in 1995. She completed a postdoctoral fellowship in the Division of Physiology at UCSD where she still holds her current position. Her laboratory uses an interdisciplinary approach combining engineering principles and lung physiology concepts to address her primary research interests that focus on aerosol transport and deposition in the lung, on lung ventilation inhomogeneities in health and disease, and more recently on upper airway dynamics in obstructive sleep apnea.

  • Center for Cyber-Physical Systems and Internet of Things and Ming Hsieh Institute for Electrical Engineering Joint Seminar Series on Cyber-Physical Systems

    Speaker: Thomas Wahl, Northeastern University

    Talk Title: Stabilizing Numeric Programs against Platform Uncertainties

    Abstract: Floating-point arithmetic (FPA) is a loosely standardized approximation of real arithmetic available on many computers today, and widely employed in cyber-physical systems. The use of approximation incurs commonly underestimated risks for the reliability of numeric software, including reproducibility issues caused by the relatively large degree of freedom for FPA implementers offered by the IEEE 754 floating-point standard. If left untreated, such problems can seriously interfere with program portability and simply our trust in numeric results.

    In this talk I discuss numeric programs' lack of robustness against platform variations, including irreproducible control flow and invariants that hold on some platforms but not others. I also demonstrate how such reproducibility violations can be repaired with low impact on performance, which results in a more stable program execution. I illustrate the use of our techniques both on decision-making and on purely numeric programs, and present an outlook to its applicability to addressing reproducibility issues among CPU and GPU versions of kernel support vector machines. Much of this is joint work with Miriam Leeser at Northeastern University, as well as our respective students.


    Biography: Thomas Wahl joined the faculty of Northeastern University in 2011. He moved to Boston from Oxford/United Kingdom, where he was a Research Officer in the Computing Laboratory (now Department of Computer Science). Prior to the Oxford experience, Wahl held a postdoctoral position at the Swiss Federal Institute of Technology (ETH) in Zurich. He obtained a PhD degree in Computer Science from the University of Texas at Austin in 2007.

    Wahl's research concerns the reliability of complex computing systems. Two domains notorious for their fragility are concurrency and numerical computing. With colleagues, Wahl has developed leading algorithms and techniques for the automated analysis of concurrent software, such as multi-threaded or data-parallel programs, using rigorous formal techniques, which are able to track down deep and unintuitive program bugs. He has also investigated how floating-point arithmetic can "hijack" a program's computation when run on non-standard architectures, such as heterogeneous and custom-made embedded platforms.

  • Aerospace & Mechanical Engineering Seminar

    Wed, Oct 25, 2017 @ 03:30 PM - 04:30 PM

    Aerospace and Mechanical Engineering

    Conferences, Lectures, & Seminars


    Speaker: Adam Steinberg, Associate Professor/University of Toronto Institute for Aerospace Studies

    Talk Title: Thermoacoustic Dynamics in Aeronautical Gas Turbine Combustors

    Abstract: Thermoacoustic instability in combustion systems refers to the tendency for small perturbations to grow into sustained high-amplitude oscillations, driven by feedback between heat release and pressure dynamics. This seminar will explore various aspects of thermoacoustic instabilities that were studied experimentally in a practical aeronautical gas turbine combustor using optical measurement techniques. Specific challenges arising in the application of optical diagnostics to high-pressure, liquid-fueled combustors will be addressed. We then will discuss two types of thermoacoustic behavior. The first involves apparently spontaneous increases and decreases in oscillation amplitude that occurred at particular operating points. The second pertains to conditions exhibiting steady and intense oscillations, but with extreme sensitivity between the operating point and oscillation amplitude. Both of these behaviors can be explained using the experimental data. Such insights help guide engine designers to more robust systems, and provide important information regarding the application of computational fluid dynamics simulations to thermoacoustically oscillating combustion systems.

    Biography: Adam Steinberg is an Associate Professor at the University of Toronto Institute for Aerospace Studies, where he holds a Canada Research Chair (Tier II) in Turbulent Reactive Flows. His research focuses on the application of laser-based measurement techniques to solve problems in fundamental and applied thermo-fluids, with particular emphasis on aerospace and power generation systems. He obtained his PhD from the University of Michigan in 2009, and worked at the German Aerospace Center (DLR) before joining the University of Toronto in 2011. He is the recipient of the inaugural Hiroshi Tsuji Early Career Research Award from the Combustion Institute, as well as several other distinctions. He is a member of the Editorial Board of Combustion and Flame and the AIAA Propellants and Combustion Technical Committee, and is a Colloquium Co-Chair for the International Symposium on Combustion.

    Wed, Oct 25, 2017 @ 07:00 PM - 08:00 PM

    Viterbi School of Engineering Student Organizations

    Student Activity


    Have you heard professors and seasoned upperclassmen throw around phrases like "510K" and "PMA" and wondered what the heck they were talking about? Or perhaps this is the first time you've heard those terms. As it turns out, you've stumbled upon a very important topic that every engineer who aspires to work in medical device industry should know about: FDA regulation. Fret not people, for we are here to help you navigate this tricky subject. ASBME and our friends at MEDesign are proud to host USC/ASBME alumni Lauren Donahue for a discussion on FDA regulation and how it affects her life as an engineer at Medtronic! Did we mention there's also going to be free food? Oh yeah, that too.
