Automatic Differentiation and its Applications
Fri, Feb 10, 2006 @ 11:00 AM - 11:50 AM
Sonny Astani Department of Civil and Environmental Engineering
Conferences, Lectures, & Seminars
Speaker:
Paul Hovland
Argonne National LaboratoryAbstractAutomatic differentiation is a technique for computing the derivatives of a function defined by a computer subprogram. We provide an introduction to automatic differentiation tools and theory and describe the role of current and next generation automatic differentiation tools in large-scale optimization, sensitivity analysis, and the solution of nonlinear PDEs. We focus on the computational costs of automatic differentiation and the trend toward tools that are more robust, easier to use, and more powerful. We conclude with a short description of our research agenda, with an emphasis on the motivational role played by current and future applications.Location: Kaprielian Hall (KAP) - rielian Hall, Room 203

Fabrication and Characterization of
Nanoscale Hybrid Structures and DevicesJia Grace Lu
Department of Chemical Engineering and Materials Science
Department of Electrical Engineering and Computer Science
University of California, IrvineIn this talk, I will describe the research on the nano materials and hybrid structures currently undertaking in my group. By integrating bottom-up synthesis technique with top-down lithographic technique, various nanostructures are fabricated, and they are characterized by different methods such as TEM, SEM, XRD, photoluminescence, photoconductance, scanning surface potential microscopy, and electrical transport measurement. These nanostructures are used to build a range of electronic devices including field effect transistors (FET), chemical sensors, and single-electron transistors (SET). For example, individual ZnO nanowire FETs are implemented as highly sensitive chemical sensors for detection of NO2, NH3, CO toxic gases. Due to a Debye screening length comparable to the nanowire diameter, the electric field applied over the back gate electrode can significantly affect the sensitivity. A strong negative gate field is also found to efficiently refresh the sensors via an electrodesorption mechanism. As another example, spin dependent transport is studied in ferromagnetic SET devices with Co/Al2O3/Al nanoscale tunnel junctions. They exhibit typical single electron tunneling behavior including Coulomb blockade and gate modulation. Magnetoconductance measurements show bell-shaped I - H curves as a result of the direct influence of the magnetic field on the superconducting gap. In addition, the magnetic moment switching in the Co electrodes from parallel to antiparallel configurations give rises to a rich phenomenon of spin transport. Different transport mechanisms based on the spin accumulation effect and the Meservey-Tedrow effect will be presented. Brief Bio-Sketch:Dr. Lu received her dual B.S. degrees in Physics and Electrical Engineering from Washington University in 1992, M.S. and Ph.D. degrees in Applied Physics from Harvard University in 1993 and 1997, respectively. Currently she holds a joint appointment in the Department of Electrical Engineering and Computer Science and the Department of Chemical Engineering and Materials Science at UC Irvine. She had received the National Science Foundation Career Award in 2002 and the Presidential Early Career Award for Scientists and Engineers in 2004.

CHRIS CHAFE: Tapping into the Internet as an Acoustical Medium Duca Family Professor of Humanities and Sciences, Stanford UniversityDirector, Center for Computer Research in Music and AcousticsEvent poster: http://www-rcf.usc.edu/~mucoaco/events/20060210-chafe.pdfABSTRACT: Recent work in network audio transport transforms advanced networks into a new kind of acoustical medium in which sound waves propagate as if traveling through air, water, or solids. Waves sent through the medium are reflected or altered as they bounce between hosts. Propagation delays are used to create echo chambers and build the resonances for "distributed musical instruments." As a side-effect, tones created by network resonances can be used to monitor the quality of the underlying network.The presentation presents three areas of research:1) auditory methods for monitoring QoS, especially for networks supporting real-time, interactive, bidirectional flows2) remote musical collaboration using professional-quality, low-latency audio3) empirical study of human factors affected by some unique acoustical properties of the mediumNetwork latency, jitter and delay asymmetry affect the speed of sound and are never uniform. By creating distributed virtual sound objects like instruments and rooms and by studying distributed ensembles, we can begin to understand this new sound world. Some effects have been measured empirically and the results contain some surprises. For example, latencies can be low enough that musicians at opposite ends of a path are essentially in the same room, and echo cancellation becomes unnecessary. Multi-channel "echo construction" can be designed to enrich the experience. For audio use, the new territory that is opening is unlike any previous telecommunications medium.BIOSKETCH: Chris Chafe is a composer/ cellist / researcher with an interest in computer music and interactive performance. The Duca Family Professor of Humanities and Sciences at Stanford University, he has been a long-term denizen of the Center for Computer Research in Music and Acoustics where he directs the center and teaches computer music courses. His doctorate in music composition was completed at Stanford in 1983 with prior degrees in music from the University of California at San Diego and Antioch College. His areas of research involve methods for computer sound synthesis based on physical models of musical instrument mechanics and "SoundWIRE," which explores musical collaboration and network evaluation using next-generation internets for high-quality sound. He has performed his music in Europe, the Americas and Asia, and composed soundtracks for documentary films. From 2001, numerous collaborations with artist Greg Niemeyer have included "Ping" (SFMOMA, Parc de la Villette, Paris and online via the Walker Art Center), "Oxygen Flute" (San Jose Museum of Art, UC's Kroeber Museum), the disc "Extrasensory Perceptions" with music from both installations, and most recently "Organum" which is a synthetic animation taking place in an invented world of larynx creatures (DVD) and led to the "Organum Play Test" for collaborative game play.Host: Elaine Chew, Viterbi Early Career, Assistant Professor of Industrial and Systems EngineeringSupported in part by the Viterbi Early Career Chair Funds, the Integrated Media Systems Center, and the Epstein Department of Industrial and Systems Engineering.For other lectures in the series, please see http://www-rcf.usc.edu/~mucoaco/events/vecc0506.html
