Developing novel technologies for wireless nanodevices and nanosystems are of critical importance for sensing, medical science, defense technology and even personal electronics. It is highly desired for wireless devices and even required for nanodevices to be self-powered without using battery. It is essential to explore innovative nanotechnologies for converting mechanical energy, vibration energy, and hydraulic energy into electric energy, aiming at building self-powered nanosystems. We have demonstrated innovative approaches for converting mechanical energy into electric energy by piezoelectric zinc oxide nanowire (NW) arrays. Based on the piezoelectric potential created by strain in nanowires and in conjunction with the presence of a Schottky barrier at the contact, our research has demonstrated the technological road map from fundamental science, engineering scale-up to technological applications of the nanogenerators. As of today, we have demonstrated “self-poweredâ€Â nanosensors that work by harvesting energy from the environment. In addition, three-dimensional solar cells have been fabricated by integrating optical fiber with nanowires for developing “hiddenâ€Â, concealed and high efficiency solar cells. This talk will focus on the energy technologies developed using ZnO nanowires as the platform.Location: James H. Zumberge Hall Of Science (ZHS) - 159

Talk Title: Rare Category Analysis
Speaker: Dr. Jingrui He
Host: Prof. Gaurav SukhatmeAbstract:
Imbalanced data sets are prevalent in many real applications. It is often the case that people are only interested in the minority classes. The focus of my thesis is rare category analysis, which refers to the problem of detecting and characterizing the minority classes in an unlabeled, imbalanced data set. In this talk, I will introduce different aspects of rare category analysis, including rare category detection for detecting examples from new minority classes, rare category characterization for identifying examples from known minority classes, co-selection of relevant features and examples from the minority classes, etc. Along with theoretical analysis, I will also present experimental results showing the effectiveness of the proposed algorithms.Bio:
Jingrui He is a Ph.D candidate in Machine Learning Department at Carnegie Mellon University. She holds an M.S. degree and a B.S. degree from Tsinghua University, P.R. China. Her research interests include statistical learning for rare category analysis, active learning, multimedia, and spam filtering.

"From Radiative Transfer Theory to Fast Algorithms for Cell Phones"Speaker:
Dr. Thomas Kailath, Stanford UniversityAbstract:
We first describe how noticing analogies between studies of the Wiener-Hopf equation in the statistical theories of prediction and filtering and in the earlier researches of V. Ambartzumian and S. Chandrasekhar in radiative transfer theory led to fast implementations of the Kalman filter for constant parameter state space systems. Further exploration led to the concept of Displacement Structure and the development of fast algorithms (and efficient integrated circuit implementations thereof) for a host of problems in several fields, including communications, control, signal processing, linear algebra and operator theory. Biography:
After his studies at the Massachusetts Institute of Technology (Sc.D., 1961), Thomas Kailath was invited by S. Golomb to join the Communications Research Group at the Jet Propulsion Laboratory in Pasadena, CA, in a section led by A. Viterbi. He also held a visiting appointment at Caltech, which perhaps had a role in his move in 1963 to Stanford University, where he is now Hitachi America Professor of Engineering, Emeritus. Over the years, aided by a stellar array of over a hundred doctoral and postdoctoral scholars, his research has ranged over several fields, including information theory, linear systems, estimation and control, signal processing, semiconductor manufacturing, probability and statistics, and matrix and operator theory. Major honors include the IEEE Education and Signal Processing Medals and the IEEE Medal of Honor in 2007. He has also held Guggenheim and Churchill Fellowships, received several honorary degrees, co-founded companies with his students, and been elected to the U.S. National Academy of Engineering, the U.S. National Academy of Sciences, the American Academy of Arts and Sciences, the Silicon Valley Engineering Hall of Fame and several foreign academies. In 2009, he received a Padma Bhushan national award from the President of India, the Blaise Pascal Medal from the European Academy of Sciences, and was elected as a Foreign Member of the Royal Society of London.Reception: 3-4pm, RTH Lobby
