    Speaker: George Varghese, Microsoft Research

    Talk Title: From EDA to NDA: Treating Networks like Hardware Circuits

    Series: CS Colloquium

    Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium

    Surveys reveal that network outages are prevalent, and outages take hours to resolve, resulting in significant lost revenue. We suggest fresh approaches based on verification and synthesis.

    First, I show how to exploit physical symmetry to scale network verification for large data centers. While Emerson and Sistla showed how to exploit symmetry for model checking in 1996, they exploited symmetry on the logical Kripke structure. We factor the symmetries into symmetries on headers and symmetries on the physical topology.

    I will then describe work we have done in synthesis. I will set the stage by describing a reconfigurable router architecture called RMT and an emerging language for programming routers called P4 (that promises to extend the boundaries of Software Designed Networks). I will then describe two synthesis efforts for flexible routers, one akin to register allocation (table layout) and one akin to code generation (packet transactions). I will focus especially on code generation and show that the all-or-nothing compilation required for wire-speed forwarding requires adapting standard compiler techniques.

    These results suggest that concepts from Electronic Design Automation (EDA) can be leveraged to create what might be termed Network Design Automation (NDA). I end by briefly exploring this vision. This is joint work with collaborators at Edinburgh, MSR, MIT, Stanford, and University of Washington.

  • Band-Engineered Complex Oxide Interfaces: New Insights and Opportunities

    Thu, Feb 11, 2016 @ 12:45 PM - 01:45 PM

    Conferences, Lectures, & Seminars

    Speaker: Professor Bharat Jalan, University of Minnesota

    Talk Title: Band-Engineered Complex Oxide Interfaces: New Insights and Opportunities

    Series: Graduate Seminar

    Abstract: Complex oxide heterostructures can show strong correlation effects, novel magnetism, high breakdown voltage, and high 2D electron density (of the order of 1014 cm-2), unattainable in traditional semiconductor heterostructures. High 2D electron densities are of particular interest for studying low-dimensional physics in narrow d-band materials, in addition to fabricating novel plasmonic field-effect devices (FETs). Recent advances in thin film growth approaches have enabled the growth of this material class in thin film and heterostructure forms with pristine structural quality (similar to that of the conventional semiconductors). However the grand challenge in the field is to obtain these materials with the high level of stoichiometric and defect control. In this talk, I will present my groups effort to address these challenges and to utilize intrinsic defects as a new degree of freedom to control materials electronic and magnetic property using the hybrid molecular beam epitaxy (MBE) approach. In particular, I will discuss the role of intrinsic defects in realizing and tailoring the 2D electron gas at perovskite oxide heterojunctions.

    I will then present a novel approach for creating high-density 2DEGs at perovskite heterojunction using internal charge transfer. 2D carrier density much higher density than expected based on resolution of the polar discontinuity at perovskite oxide heterojunctions can be achieved via internal charge transfer using band-engineered interfaces. Combining DFT modeling and experiments using x-ray photoelectron spectroscopy, scanning transmission electron microscopy, electron energy loss spectroscopy, energy dispersive x-ray spectroscopy and electronic transport measurements, I will discuss the origin of these carriers, dimensionality and transport mechanisms. Finally, I will discuss how electron and hole doping via band-engineered approaches can be achieved, which may provide an exceptional route to revisit the electronic phase diagrams of transition metal oxides in the clean doping limit.

    This work is supported through the University of Minnesota MRSEC under awards DMR-1420013.

    Conferences, Lectures, & Seminars

    Speaker: Dr. Michael Friedlander, UC Davis

    Talk Title: Level-set methods for convex optimization

    Series: CommNetS

    Abstract: Convex optimization problems in a variety of applications have favorable objectives but complicating constraints, and first-order methods are not immediately applicable. We propose an approach that exchanges the roles of the objective and constraint functions, and instead approximately solves a sequence of parametric problems. We describe the theoretical and practical properties of this approach for a broad range of problems, including low-rank semidefinite optimization problems.
    Joint work with A. Aravkin, J. Burke, D. Drusvyatskiy, S. Roy.

    Biography: Michael P. Friedlander is a Professor of mathematics at the University of California, Davis. He received his PhD in Operations Research from Stanford University in 2002, and his BA in Physics from Cornell University in 1993. From 2002 to 2004 he was the Wilkinson Fellow in Scientific Computing at Argonne National Laboratory. He has held visiting positions at UCLA's Institute for Pure and Applied Mathematics (2010), and at Berkeley's Simons Institute for the Theory of Computing (2013). He serves on the editorial boards of SIAM J. on Optimization, SIAM J. on Matrix Analysis and Applications, SIAM J. on Scientific Computing, and Mathematical Programming Computation. His research is primarily in developing numerical methods for large-scale optimization, their software implementation, and applying these to problems in signal processing and machine learning.

  • Astani Civil and Environmental Engineering Ph.D. Seminar

    Thu, Feb 11, 2016 @ 03:00 PM - 04:00 PM

    Sonny Astani Department of Civil and Environmental Engineering

    Conferences, Lectures, & Seminars

    Speaker: Dr. Shiho Kawashima, Columbia University

    Talk Title: Thixotropy of Fresh Cement-Based Systems

    Abstract: Over its lifetime, cement-based materials transition from behaving as a near-Newtonian fluid to a viscoelastic fluid-solid to eventually a rock-like solid. And although the first two phases are fleeting compared to the third phase, this earlier life period is intimately tied to materials processing.
    Therefore the corresponding properties are critical in determining the efficiency of the placement process during construction, as well as the eventual performance of the structure in place. This requires that the rheological properties of the material be well characterized and controlled. During placement the material undergoes a wide range of deformations -“ very large during processes such as pouring and pumping, but then diminishingly small after placement when it is essentially at rest. This talk will cover studies that investigate the specific rheological aspect of thixotropy in cement paste and mortar systems that incorporate highly-purified attapulgite clay through static shear and dynamic rheological protocols that span wide timescales and magnitudes of deformations and rates.

    Shiho Kawashima is an Assistant Professor of Civil Engineering and Engineering Mechanics at Columbia University. Her work is in experimental cement and concrete research, which aims to tie nano-microstructural behavior to macroscale structural response. She specializes in cement rheology, particularly in the development of innovative measurement techniques to further the understanding of the structural and temporal evolution of the fresh-state microstructure of cementitious systems. She is also interested in the design of nanocomposites and sustainable infrastructural materials. She received her B.S. in Civil Engineering and Engineering Mechanics at Columbia University, and her M.S. and Ph.D. in Civil Engineering at Northwestern University.
