    Speaker: Steve George, Depts. of Chemistry and Mechanical Engineering, University of Colorado, Boulder

    Talk Title: Hybrid Organic-Inorganic Films Fabricated Using Atomic and Molecular Layer Deposition

    Series: Lyman L. Handy Colloquia

    Abstract: Atomic layer deposition (ALD) and molecular layer deposition (MLD) are based on sequential, self-limiting surface reactions that produce atomic layer controlled and conformal thin film growth. ALD can deposit inorganic films and MLD can deposit organic films containing inorganics. ALD and MLD can also be used together to fabricate a wide range of alloy films with variable inorganic and organic composition. This talk will focus on the growth and properties of metal alkoxide films known as “metalcones” that are grown using metal precursors and various organic alcohols. The talk will highlight the tunable mechanical properties of alucone alloys grown using Al2O3 ALD and alucone MLD and the tunable electrical conductivity of zincone alloys grown using ZnO ALD and zincone MLD. In addition, the talk will discuss the pyrolysis of hybrid organic-inorganic films to produce conducting metal oxide/carbon composite films.

  • Munushian Seminar - Tsu-Jae King Liu

    Fri, Feb 07, 2014 @ 02:00 PM - 03:00 PM

    Ming Hsieh Department of Electrical and Computer Engineering

    Conferences, Lectures, & Seminars


    Speaker: Dr. Tsu-Jae King Liu, UC Berkeley

    Talk Title: Moore’s Law - What’s Next?

    Abstract: Steady miniaturization of transistor has yielded continual improvements in integrated-circuit (IC) performance
    and cost per function over the past four decades, resulting in the proliferation of information processing technology
    with dramatic impact on virtually every aspect of life in modern society. Continued transistor scaling will not be as straightforward in the future as it has been in the past, however, as fundamental limits are approached. This is already
    apparent from the slowdown in voltage scaling, which has added a new constraint for IC design and exacerbates the emerging issue of electronics energy consumption. This seminar will present a vision of the future of information processing devices and discuss alternative approaches for improving their functionality, cost per function and energy efficiency to usher in the Age of Ambient Intelligence to the benefit of our global society.

    Biography: Tsu-Jae King Liu received the B.S., M.S., and Ph.D. degrees in Electrical Engineering
    from Stanford University. From 1992 to 1996 she was a Member of Research Staff at the Xerox Palo Alto Research Center (Palo Alto, CA).

  • Astani CEE Ph.D. Seminar

    Fri, Feb 07, 2014 @ 04:00 PM - 05:00 PM

    Sonny Astani Department of Civil and Environmental Engineering

    Conferences, Lectures, & Seminars


    Speaker: Professor Emile A. Okal , Northwestern University, Ullinois

    Talk Title: The implosive component of the 2013 Okhotsk Sea deep earthquake: Evidence from radial modes and constraints from geodetic data

    Abstract: Ever since Bridgman's (1945) original suggestion, the presence of an implosive component in the source of deep earthquakes has long been a passionately debated subject, which is re-openened by the occurrence of the 2013 Sea of Okhotsk earthquake, the largest ever recorded deep event.
    The analysis of the fundamental and first overtone radial modes, 0s0 and 1s0, allows the resolution of such a component without trade-off with the relevant deviatoric component. We document the presence of an implosive component valued at 2 percent of the scalar moment tensor (but 9 percent of the deviatoric component exciting radial modes). The implosive component is also resolved
    by CMT inversion when the zero-trace constraint is relaxed, but with a significantly larger amplitude (8 percent of the scalar moment).
    The near field of three-dimensional static deformation by the earthquake is reconstructed from data at permanent GPS stations in the epicentral area, with maximum observed deformations on the order of 1 cm (horizontal) to 2 cm (vertical). Preliminary modeling indicates that the influence of the proposed imnplosive components (especially as derived from CMT inversion) may be resolvable from this dataset at critically located GPS stations, of which a full investigation will be presented.

    We further show that a small tsunami from this very deep earthquake was detected at two regional DART buoys, and that its amplitude (3 to 4 mm peak-to-peak) is well accounted for by a number of crude, back of the envelope calculations.

  • Munushian Seminar - Peidong Yang

    Mon, Feb 10, 2014 @ 02:00 PM - 03:00 PM

    Ming Hsieh Department of Electrical and Computer Engineering

    Conferences, Lectures, & Seminars


    Speaker: Peidong Yang, UC Berkeley

    Talk Title: Nanowire Technology and Terawatt Challenge

    Abstract: Semiconductor nanowires, by definition, typically have cross-sectional dimensions that can be tuned from 2–200 nm, with lengths spanning from hundreds of nanometers to millimeters. After more than a decade of research, nanowires can now be synthesized and assembled with specific compositions, heterojunctions and architectures. This has led to a host of nanowire photonic and electronic devices. Because of their unique structural, chemical and physical properties, these nanoscopic one-dimensional nanostructures can also play a significant role in terawatt-scale energy conversion and storage. Currently the amount of energy required worldwide is on the scale of terawatts, and the percentage
    of renewable energy in the current energy portfolio is quite limited. Developing of cost-effective clean energy technology
    becomes imperative. I will show two examples from my group, approaching this problem in two different directions. The first relates to saving energy, by developing nanostructured silicon thermoelectrics to do waste heat recovery; and the second is to develop nanostructures for solar energy conversion, either directly to electricity or to liquid fuels through artificial photosynthesis.

    Biography: Peidong Yang received a B.S. in chemistry from University of Science and Technology of China in 1993 and a Ph.D. in chemistry from Harvard University in 1997. He did postdoctoral research at University of California, Santa Barbara
    before joining the faculty in the department of Chemistry at the University of California, Berkeley in 1999. He is currently professor in the Department of Chemistry, Materials Science and Engineering; and a senior faculty scientist at the Lawrence Berkeley National Laboratory. He is S. K. and Angela Chan Distinguished Chair Professor in Energy. He was recently elected as MRS Fellow, and the member of American Academy of Arts and Sciences. Prof. Yang is the founder of the Nanoscience subdivision within American Chemical Society. He has co-founded two startups Nanosys Inc. and Alphabet Energy Inc. He is the recipient of MRS Medal, Baekeland Medal, Alfred P. Sloan research fellowship, the Arnold and Mabel Beckman Young Investigator Award, National Science Foundation Young Investigator Award, MRS Young Investigator
    Award, Julius Springer Prize for Applied Physics, ACS Pure Chemistry Award, and Alan T. Waterman Award. His main research interest is in the area of one dimensional semiconductor nanostructures and their applications in nanophotonics and energy conversion.

  • Approaches to 3D Image Reconstruction from Motion Scattered Diffusion Weighted MRI of the Fetal Brain

    Tue, Feb 11, 2014 @ 03:00 AM - 04:00 PM

    Ming Hsieh Department of Electrical and Computer Engineering

    Conferences, Lectures, & Seminars


    Speaker: Prof. Colin Studholme, University of Washington

    Talk Title: Approaches to 3D Image Reconstruction from Motion Scattered Diffusion Weighted MRI of the Fetal Brain

    Series: Medical Imaging Seminar Series

    Abstract: Magnetic resonance based diffusion weighted imaging provides a unique window into tissue microstructure and brain connectivity. Over the last 7 years there has been significant interest in adapting the technique using post-processing to enable imaging of the unsedated fetal brain in-utero. This talk will review work on reconstruction of diffusion image measurements from single shot multi slice diffusion MRI data, where significant motion has occurred between the acquisition of slices. To form a complete 3D image of diffusion properties during head motion each diffusion weighted slice must be accurately relocated and orientated within a common anatomical coordinate system, and the spatially scattered slices then used to estimate a model of diffusion properties on a regular voxel lattice. This talk will look at these two problems and review the current alternatives to solving them numerically for clinically acquired data. Results on human and primate fetal brain data will be included to illustrate the capabilities and limitations for practical studies of fetal brain growth.

  • CS Colloquium: Dr. Andrew Lemieux: The WILD LEO Project: Using Technology and Training to Increase the Effectiveness of Anti-Poaching Teams in Uganda

    Tue, Feb 11, 2014 @ 11:15 AM - 12:20 PM

    Thomas Lord Department of Computer Science

    Conferences, Lectures, & Seminars


    Speaker: Dr. Andrew Lemieux, WILD LEO Project

    Talk Title: The WILD LEO Project: Using Technology and Training to Increase the Effectiveness of Anti-Poaching Teams in Uganda

    Series: CS Colloquium

    Abstract: The WILD LEO Project is an attempt to provide anti-poaching teams with the technology and training necessary to undertake advanced intelligence gathering and analysis. The Wildlife Intelligence and Leadership Development (WILD) training protocols were specifically developed for Law Enforcement Officers (LEOs) in Queen Elizabeth Protected Area, Uganda. The WILD LEO team consists of foot patrol rangers, crime analysts, prosecutors and commanders.

    Using digital cameras with integrated GPS units, the foot patrol rangers are creating a spatially referenced, photographic database of poaching activity. The crime analysts use these photos to prepare patrol coverage maps and maps of illegal activity to help commanders make informed deployment decisions. The geo-referenced photos are also used by the prosecution team as courtroom evidence to prove poachers were operating inside the protected area.

    By design, The WILD LEO Project utilizes low-cost technology and open source software to ensure sustainability in law enforcement operations with limited budgets. This presentation will discuss the project’s implementation, initial findings, potential for expansion, and the utility of WILD LEO for interdisciplinary research.


    Biography: Originally trained as a biochemist who studied diabetes, lung injury and space biology at the University of Arizona (BS 2005, MS 2006), Andrew switched disciplines after graduation to pursue his research interests in criminology. He completed his graduate studies at the Rutgers School of Criminal Justice (MA 2008, PhD 2011) where he studied a variety of topics including wildlife crime, visitor crime and time-based risk assessments of violence.

    Poaching prevention is Andrew's main area of expertise and comprises the majority of his research agenda. He currently directs the WILD LEO Project in Queen Elizabeth and Murchison Falls National Parks in Uganda. This is an on-going collaboration with the Uganda Wildlife Authority and Uganda Conservation Foundation that uses technology and training to increase ranger efficiency with advanced intelligence gathering and analysis techniques. The goals of the project are to (a) give commanders better information for deployment decision making, (b) increase poacher apprehension and (c) increase poacher conviction rates.

  • CS Colloquium: Jonathan Ullman (Harvard U): Privacy and the Complexity of Simple Queries

    Tue, Feb 11, 2014 @ 04:00 PM - 05:30 PM

    Thomas Lord Department of Computer Science

    Conferences, Lectures, & Seminars


    Speaker: Jonathan Ullman, Harvard University

    Talk Title: Privacy and the Complexity of Simple Queries

    Series: CS Colloquium

    Abstract: The goal of differentially private data analysis is to design algorithms for analyzing datasets while ensuring that sensitive information about individuals is not revealed. In this talk I will present both new lower bounds and new algorithms for differentially private data analysis. On the negative side, I will present some new, nearly-optimal lower bounds on the amount of data required to release differentially private statistics on high-dimensional datasets. These results show that there is a significant "price of differential privacy" in high-dimensional datasets. We prove these lower bounds using a cryptographic primitive called a fingerprinting code that we show is closely connected to differentially private data analysis. On the positive side, I will present efficient algorithms for computing differentially private contingency tables, using techniques from computational learning theory.

    Biography: Jon Ullman is a postdoctoral fellow at the Center for Research on Computation and Society at Harvard University. He recently completed his Ph.D., also at Harvard, where he was advised by Salil Vadhan and was a Siebel Scholar. He is interested in the foundations of data privacy and its connections to other areas of theoretical computer science such as cryptography, learning theory, and game theory.

    Sonny Astani Department of Civil and Environmental Engineering

    Conferences, Lectures, & Seminars


    Speaker: Xing Xie, Stanford University

    Talk Title: Advanced Materials and Nanotechnology for Environmental Applications

    Abstract: Advanced materials and nanotechnology are powerful tools that have been changing our lives dramatically. However, we are still facing very challenging environmental issues, such as water contamination, air pollution, and climate change. To tackle these environmental issues, my research focuses on applying advanced materials and nanotechnology to enhance the performance of existing environmental technologies, and to develop new technologies that can provide better solution to various environmental issues. In this presentation, I will introduce two different environmental applications. One is about nano-enhanced microbial electrochemical cells for wastewater treatment and energy recovery. I have developed 3D bio-electrodes for microbial electrochemical cells with superior performance. I also have invented a new microbial electrochemical device, named “microbial battery”, achieving higher than 30% energy efficiency. The other application is about nano-assisted new technologies for efficient water disinfection. In one example, strong electric field generated near the tips of nanowire structures is applied to kill bacteria and viruses in water. Removal efficiencies higher than 6-log have been achieved with retention times less than one second. In another example, water disinfection is realized by employing silver nanoscavengers, which are nanodisks with magnetic cores and silver capping layers. The silver nanoscavengers can be separated from treated water effectively after treatment and reused for thousands of times.

    Biography: Xing Xie received his B.S. (2006) and M.S. (2008) degrees from Tsinghua University, and he is currently a Ph.D. candidate in the Department of Civil and Environmental Engineering at Stanford University and a Henry Fan Fellow supported by the Stanford Interdisciplinary Graduate Fellowship. His research mainly focuses on applying advanced materials and nanotechnology for environmental applications. He has worked on many projects related to microbial electrochemical cells, water disinfection, water reuse, algae control, mixing entropy batteries, electrochemical capacitors, and Li-ion batteries. He has published more than 20 peer-reviewed articles in leading journals, including PNAS, Nature Communications, Nano Letters, Energy & Environmental Science, and ACS Nano. He received the Larry C. K. Yung Fellowship in 2008-2009, the David and Lucile Packard Foundation Fellowship in 2009-2011, and the Graduate Student Award in Environmental Chemistry from the American Chemical Society in 2012.

    Speaker: Ms. Ermin Wei, Electrical Engineering and Computer Science, Massachusetts Institute of Technology

    Talk Title: "Distributed Optimization and Market Analysis of Networked Systems"

    Abstract: In the interconnected world of today, large-scale networked systems are ubiquitous. Some examples include communication networks, electricity grid and sensor networks. In this talk, we describe two recent results related to these networked systems. In the first part, we present a fast distributed asynchronous Alternating Direction Method of Multipliers (ADMM) based method for solving general separable convex problems in large-scale systems, which can be applied to the LASSO and many other machine learning problems. We show that this method has convergence guarantee and the best known rate of convergence. In the second part, we discuss our model on the competitive equilibrium in electricity markets where price fluctuation imposes difficulties in budgeting and planning. We introduce an explicit penalty on the price volatility and establish that price volatility penalty can be implemented via the use of storage.

    Talk Title: Engineering hydrogels as synthetic extracellular matrices for cell culture and tissue regeneration

    Series: Cornelius Pings Lecture

    Abstract: Methods for culturing mammalian cells in a biologically relevant context are increasingly needed to study cell and tissue physiology, expand and differentiate progenitor cells, and to grow replacement tissues for regenerative medicine. Two dimensional culture has been the paradigm for in vitro cell culture; however, evidence and intuition suggest that cells behave differently when they are isolated from the complex architecture of their native tissues and constrained to petri dishes or material surfaces with unnaturally high stiffness, polarity, and surface to volume ratio. As a result, biologists are often faced with the need for a more physiologically relevant 3D culture environment, and many researchers are realizing the advantages of hydrogels as a means of creating custom 3D microenvironments with highly controlled chemical, biological and physical cues. Further, the native extracellular matrix (ECM) is far from static, so ECM mimics must also be dynamic to direct complex cellular behavior. In general, there is an un-met need for materials that allow user-defined control over the spatio-temporal presentation of important signals, such as integrin-binding ligands, growth factor release, and biomechanical signals. Developing such hydrogel mimics of the ECM for 3D cell culture is an archetypal engineering problem, requiring control of numerous properties on multiple time and length scales important for cellular functions. New materials systems have the potential to significantly improve our understanding of how cells receive information from their microenvironment and the role that these dynamic processes may play in controlling the stem cell niche to cancer metastasis. This talk will illustrate our recent efforts to advance hydrogel chemistries for 3D cell culture and dynamically control biochemical and biophysical properties through orthogonal, photochemical reaction mechanisms.

    Speaker: Fabio Rinaldi, Senior Researcher, Lecturer, and PI at the University of Zurich, Switzerland

    Talk Title: OntoGene & SASEBio: biomedical text mining research at UZH

    Series: AISeminar

    Abstract: There are vast amounts of knowledge encoded in the scientific literature which could be made more easily accessible and useful to a broader range of users through the application of more effective software tools. Text mining is a new discipline which seeks to provide ways to find, extract and manipulate the knowledge which still remains to a large extent hidden in the literature.

    Text mining tools can already provide a very effective way to extract some specific types of information, but are not yet so advanced that their results can be used without human verification by domain experts. Therefore one very promising area of application of text mining technologies is within the process of database curation.

    The need to efficiently retrieve key information derived from experimental results, and published in the scientific literature, is of fundamental importance in biology. In order to help biologists, as well as in some cases medical practitioners, to efficiently find such
    information in the enormous quantity of published articles, several public and private institutions fund the construction and maintenance of specialized databases, which have the role to collect specific knowledge items and provide them in an easily accessible format. There are several dozens of such databases, each specializing in a
    particular domain of the life sciences [1].

    In this talk I will describe text mining activities conducted by my research group at the University of Zurich (OntoGene: www.ontogene.org). The OntoGene group is supported by the Swiss National Science Foundation (project SASEBIO: Semi-Automated Semantic
    Enrichment of the Biomedical Literature) and by Roche Pharmaceuticals. The SASEBio project focuses in particular on applications of text mining technologies to the process of biomedical database curation.

    The OntoGene team has participated in several competitive evaluations of biomedical text mining technologies, obtaining competitive results in all of them. Some of these results will be discussed in the talk. Additionally, I will present ODIN (OntoGene Document Inspector), an interactive tool which allows database curators to leverage upon the results of the OntoGene text mining system and use them in their
    curation tasks.

    The OntoGene text mining system is based on a scalable entity recognition component with a semi-automated organism-based disambiguation module, an in-house dependency parser, and a flexible relation mining approach. The OntoGene team has participated in several biomedical text mining challenges (BioCreative, BioNLP,
    CALBC), obtaining competitive results in all of them. Some of these results will be discussed in the talk.

    The OntoGene Document Inspector (ODIN) is an interactive tool which allows database curators to leverage upon the results of the OntoGene text mining system and use them in their curation tasks. One recent version of the system has been tested in the curation process of the Pharmacogenomics Knowledge Base (PharmGKB), and another version
    adapted for the Comparative Toxicogenomics Database in the context of
    a BioCreative challenge.

    Speaker: Jungwoo Lee, Ph.D., Postdoctoral Research Fellow, Massachusetts General Hospital, Harvard Medical School

    Talk Title: Enabling 3D Microenvironments for Bone Marrow Bioengineering

    Abstract: Bone marrow, a sponge-like gelatinous and vascular tissue located at the inside of bone matrix is a vital part of human body as a major reservoir of adult stem cells, an exclusive site for hematopoiesis, and a key regulator of body homeostasis via continuous cellular trafficking. Bone marrow is also deeply involved in metastasis of many prominent tumors e.g. breast and prostate tumors as a direct metastatic target for disseminated circulating tumor cells and/or a potent instigator of their metastatic spread to other peripheral tissue sites. Therefore, in depth understanding of bone marrow biology is critical to advance many fields of modern medicine. However, probing the bone marrow microenvironments has been challenging because of its anatomical inaccessibility, tissue complexity and lack of relevant preclinical models. In this talk, I will introduce bioengineering strategies to develop functional and standardized bone marrow models based on 3D hydrogel scaffolds that closely emulate physical and anatomical features of the bone marrow in a controlled and reproducible manner. Specifically I will discuss development of in vitro and in vivo human bone marrow tissue analogues combining the 3D hydrogel scaffolds with primary human bone marrow stromal cells that recapitulate essential bone marrow functions with high analytical power. In the last part of my talk, I will introduce an exciting application of our in vivo bone marrow model for studying human prostate tumor metastasis with several enabling features. Biomimetic design of 3D hydrogel scaffolds coupled with a powerful set of material, microfluidic, imaging and cellular engineering tools offer unique opportunity to build functional and analytical preclinical bone marrow models for studying many complex, dynamic physiological and pathological processes in the bone marrow.

    Information Sciences Institute

    Conferences, Lectures, & Seminars


    Speaker: Hal Daume, University of Maryland

    Talk Title: "Predicting Linguistic Structures Accurately and Efficiently"

    Series: Natural Language Seminar

    Abstract: Many classic problems in natural language processing can be cast as building mapping from a complex input (e.g., a sequence of words) to a complex output (e.g., a syntax tree or semantic graph). This task is challenging both because language is ambiguous (learning difficulties) and represented with discrete combinatorial structures (computational difficulties). Often these are at odds: the features you want to add to decrease learning difficulties cause nontrivial additional structure yielding worse computational difficulties.

    I will begin by discussing algorithms that side-step the issue of combinatorial blowup and aim to predict an output structure directly. I will then present approaches that explicitly learn to trade-off accuracy and efficiency, applied to a variety of linguistic phenomena. Moreover, I will show that in some cases, we can actually obtain a model that is faster and more accurate by exploiting smarter learning algorithms.

  • Network Scheduling with a Mix of Heavy-tailed and Light-tailed Traffic

    Tue, Feb 18, 2014 @ 11:00 AM - 12:00 PM

    Ming Hsieh Department of Electrical and Computer Engineering

    Conferences, Lectures, & Seminars


    Speaker: Eytan Modiano, Massachusetts Institute of Technology

    Talk Title: Network Scheduling with a Mix of Heavy-tailed and Light-tailed Traffic

    Abstract: We describe recent results on scheduling and routing in the presence of a mix of heavy-tailed and light-tailed traffic. In particular, we show that when some of the traffic in the network is heavy-tailed, under max-weight scheduling the expected delay is unbounded even for the light-tailed traffic. This surprising result shows that max-weight scheduling is delay unstable when some of the traffic is heavy-tailed. Further, we provide examples where max-weight scheduling can lead to delay propagation throughout the network.

    We then study the class of throughput optimal max-weight-α scheduling policies, and show that with an appropriate choice of the α parameters, the light queue can achieve bounded expected delay. Moreover, we derive an exact asymptotic characterization of the steady-state queue length distributions. We extend our results to the case where the links have intermittent on-off connectivity and show that the behavior of the queue occupancy distribution strongly depends on the connectivity parameters and the arrival rates to the queues. Finally, we consider backpressure routing in the presence of heavy tailed traffic, and describe settings where backpressure routing also leads to delay propagation throughout the network.

    This talk is based on joint work with Krishna Jagannathan, Mihalis Markakis, and John Tsitsiklis


    Biography: Eytan Modiano received his B.S. degree in Electrical Engineering and Computer Science from the University of Connecticut at Storrs in 1986 and his M.S. and PhD degrees, both in Electrical Engineering, from the University of Maryland, College Park, MD, in 1989 and 1992 respectively.

    Speaker: Taesoo Kim, MIT CSAIL

    Talk Title: Intrusion Recovery Using Selective Re-execution (Undo Computing)

    Series: CS Colloquium

    Abstract: Virtually any computer system can be compromised. New software vulnerabilities are discovered and exploited daily, but even if the software is bug-free, administrators may inadvertently make mistakes in configuring permissions, or unaware users may click on buttons in application installers with little understanding of its consequences. Recovering from those inevitable compromises leads to days and weeks of wasted effort by users or system administrators, yet with no conclusive guarantee that all traces of the attack have been cleaned up. This talk will present our work on "undo computing," which aims to restore system integrity by efficiently and precisely detecting and undoing changes made by past intrusions.

    Biography: Taesoo Kim is a PhD student at MIT, CSAIL. He is interested in building systems that have strong yet intuitive underline principles for why it should be just secure. Those principles include the simple design of a system, analysis of its implementation, and clear separation of trusted components. He has BS at KAIST (2009), and SM at MIT (2011), both in CS.

    Speaker: Keyue Shen, Ph.D., Massachusetts General Hospital, Harvard Medical School

    Talk Title: Engineering Cell Microenvironments for Cancer Therapeutics

    Abstract: Host stromal cells have been increasingly recognized as key regulators in cancer microenvironment. As cancer progresses, normal suppressive stroma is replaced by an activated, cancer-promoting one. This is accompanied by suppression of tumor-inhibiting infiltrating lymphocytes, and an increasingly disorganized tumor-stroma interface. In this talk, I will present subcellular microengineering approaches to control T cell activation through spatial and mechanical cues for cancer immunotherapy. I will also demonstrate an interfacial interaction model for understanding spatially resolved tumor-stromal signaling and discovering cancer chemotherapeutics that target the tumor-stroma interface.

    Speaker: Dr. Guanghui (George) Lan, Assistant Professor, Dept of Industrial & Systems Engineering, University of Florida

    Talk Title: "Stochastic and Nonlinear Optimization for Large-Scale Data Analysis"

    Abstract: Optimization has found widespread applications in data analysis during the past few years. Prominent examples include a variety of stochastic optimization models for machine learning (e.g., regression, classification, dictionary learning), and deterministic optimization models for inverse problems (e.g., compressed sensing, image reconstruction and matrix completion). Although being very encompassing, such optimization models from data analysis are often challenging to solve, mainly due to their high problem dimensionality, inherent data uncertainty, pervasive structure ambiguity, along with the frequent need to solve them in real time. In this talk, I will survey some recent advances to tackle the aforementioned big-data challenges in optimization. In particular, I will highlight: i) novel stochastic optimization methods that can handle data uncertainty in an optimal manner, based on our work on stochastic approximation; and ii) new deterministic optimization methods that converge faster and require little structural information, based on our work on level methods. I will provide showcases for the effectiveness of these techniques in machine learning and biomedical imaging.

    Speaker: Renee Miller , Bell Canada Chair of Information Systems University of Toronto

    Talk Title: Big Data Curation

    Series: Artificial Intelligence Seminar

    Abstract: A new mode of inquiry, problem solving, and decision making has become pervasive in our society, consisting of applying computational, mathematical, and statistical models to infer actionable information from large quantities of data. This paradigm, often called Big Data Analytics or simply Big Data, requires new forms of data management to deal with the volume, variety, and velocity of Big Data. Many of these data management problems can be described as data curation. Data curation includes all the processes needed for principled and controlled data creation, maintenance, and management, together with the capacity to add value to data. In this talk, I describe our experience in curating several open data sets. I overview how we have adapted some of the traditional solutions for aligning data and creating semantics to account for (and take advantage of) Big Data.

    Series: CS Colloquium

    Abstract: As more complex security challenges emerge, cryptography is called to provide provably secure solutions for a wide range of applications. Bridging the gap between theory and applications is perhaps the biggest challenge of contemporary cryptography. In this talk I discuss how combining ideas from game theory and cryptography provides the basis for the design of highly efficient, more resilient, and simpler provably secure protocols. I demonstrate this for the problem of secure computation, which has numerous applications, e.g., privacy preserving data mining and secure cloud computing. I further discuss recent developments on concrete efficiency of secure multi-party computation protocols which indicate that we can realistically expect large scale deployments in the next few years.

    Talk Title: Toxico-chemical properties of size-fractionated airborne particulate matter and implications for human health / Measuring the Impact of Personal Control and Energy Use through the Use of Immersive Virtual Environments.

    Abstract: Presenter: Arian Safari

    Exposure to atmospheric particulate matter (PM) has been linked to several adverse health effects, including but not limited to respiratory and cardiovascular diseases in addition to neurological disorders. There is growing literature supporting the hypothesis that one of the important pathways underlying these adverse health endpoints is the oxidative stress (e.g. ROS generation) that derives from the interaction of PM with cells. Elevated ROS levels can alter the redox status of the cell and consequently trigger a series of acute and chronic responses such as pulmonary inflammation and mitochondrial damage. This talk would focus on the PM-induced oxidative stress, its temporal and spatial variations, its relationship with chemical composition and PM emission sources and implications for toxicity assessment and human health. Moreover, a summary of the results of our recent studies in the Los Angeles south coast air basin will be discussed.

    Title: Measuring the Impact of Personal Control and Energy Use through the Use of Immersive Virtual Environments.


    Absract:

    Recent studies have focused on increasing energy efficiency in commercial buildings through technological means (e.g., efficient HVAC systems, sensors and sensing systems). However, most studies underestimate the impact of occupants’ behavioral choices. This presentation focuses on measuring the impact of personal control and energy consumption behaviour through the use of immersive virtual environments. The presentation will focus on two main topics the (1) evaluation of human interaction within immersive virtual environments compared to the physical environments and (2) the impact of personal control on lighting use in office environments. The presentation is broken down into the following components: discussion of the problem statement, use of immersive virtual environments to study alternative designs, brief discussion of the pilot experiments, and future works.

    Talk Title: Engineering Materials to Support Tissue Regeneration

    Abstract: There is increasing evidence that the efficacy of tissue regeneration is likely dependent on creating a suitable microenvironment that can support cell function. Moreover, the design of successful engineered therapies for tissue regeneration relies on discerning how cell behavior in the biological microenvironment can be modulated by chemical and physical cues. In the first part of this work, the combinatorial effect of stiffness and micro-scale topographical cues on cell proliferation and gene expression is investigated in 2D and 3D. Results demonstrate that regulation of extracellular matrix production by cells on 2D and 3D cultures can be influenced via microscale physical cues alone and highlight the role of stiffness on the physical regulation of cells. Furthermore, biocompatible microstructures are developed as injectable micro-scaffolds and as growth factor delivery devices to influence tissue regeneration in vivo after myocardial infarction in the rat model. The major objective in the development of engineered tissues is to design and create scaffolds that will properly integrate with the host tissue to support the regenerative process. In the second part of this work, a strategy for abdominal wall repair is developed by engineering a mechanically robust composite scaffold laden with human mesenchymal stem cells (hMSCs) designed to improve therapeutic outcomes. My studies are focused on designing and fabricating engineered implantable materials that support tissue regeneration by influencing the in vivo microenvironment to direct cells to regenerative behavior.

    Talk Title: Smarter Lithography: Top-Down Control of Nanometer-Length-Scale Self-Assembly

    Abstract: The future of nanotechnology generally and the integrated circuit industry in particular depend on the ability to control and pattern complex structures at the nanometer length scale. We will discuss methods we have developed that use electron and ion beams to pattern structures at the single-nanometer length scale. However, covering large areas with nanometer-scale beams is a slow and expensive process, leading some to suggest that chemical and biological self-assembly might better address the future industrial needs in this area. The question is then, how to control self-assembly to create the kinds of flawless and arbitrary patterns the semiconductor industry now uses routinely in the fabrication of microchips? We will discuss a solution to this problem in which we pattern only a sparse structure and then using directed self-assembly of block copolymers, fill in the remaining space. The trick is to achieve a maximum of control and complexity in the final pattern with a minimum of expensive top-down lithography. The result is a surprising degree of control and perfection in patterning systems that would otherwise produce random patterns. We can even control double-layer patterns by using just a single layer of sparse electron-beam-defined posts. The methods take advantage
    of the natural tendencies of the block copolymers to form ordered linear arrays, with the posts serving to guide the arrays during the assembly process. A future vision of lithography, where engineering and chemistry work together to construct complex and useful nanometer-length-scale patterns is envisioned as a result of this work.

    Biography: Professor Karl K. Berggren is a Professor of Electrical Engineering at Massachusetts Institute of Technology (MIT), Department of Electrical Engineering and Computer Science, where he heads the Quantum Nanostructures and Nanofabrication Group. He received his Ph.D. in Physics from Harvard University

    Speaker: Dr. John Gunnar Carlsson, Assistant Professor, Department of Industrial and Systems Engineering, University of Minnesota

    Abstract: Geography is a natural factor that must be explicitly considered in many problems in operations research, such as facility location, vehicle routing, and network design. Scientifically speaking, one of the major difficulties that geographic resource allocation problems pose is their interdisciplinary nature; in order to determine an optimal solution to such a problem, one must combine tools from a variety of disciplines, such as mathematical optimization, computational geometry, geometric probability theory, and geospatial analysis. In this talk, we show how to apply these tools to solve two fundamental logistical problems: the first is a high-level analysis of a hub-and-spoke network design problem, and the second is a districting problem in which the goal is to partition a geographic territory so as to balance the workloads of a collection of service facilities or vehicles.

  • CS Colloquium: David Chu (Microsoft Research) - Surmounting two challenges of cloud gaming for mobile devices: network latency and server multi-tenancy

    Speaker: David Chu, Microsoft Research

    Talk Title: Surmounting two challenges of cloud gaming for mobile devices: network latency and server multi-tenancy

    Series: CS Colloquium

    Abstract: Gaming on mobile devices is very popular. Cloud gaming such as Sony PlayStation's Now -- where remote servers perform game execution and rendering on behalf of thin clients that simply send input and display output frames -- appears to be well-suited for mobile devices, promising any device the ability to play any game any time. However, cloud gaming must confront network latency and server multi-tenancy. This talk introduces these two challenges, and our two respective solutions, DeLorean and DeeJay.

    For latency, wireless network round trip times (RTTs) often exceed thresholds above which gamers find responsiveness acceptable. We present DeLorean, a speculative execution system for mobile cloud gaming that is able to mask latency. DeLorean produces speculative rendered frames of future possible outcomes, delivering them to the client one entire RTT ahead of time; clients perceive little latency. To achieve this, DeLorean combines: 1) future input prediction; 2) state space subsampling and time shifting; 3) misprediction compensation; and 4) bandwidth compression. This work is a collaboration with the University of Michigan.

    For multi-tenancy, a single server must carefully schedule the GPU across multiple game instances that each have their own real-time latency and throughput requirements. Moreover, it must gracefully handle overload when more clients join than anticipated. We are in the process of building DeeJay, a system that 1) schedules GPU-bound jobs with latency and throughput constraints, and that 2) minimally degrades visual game quality upon system overload.

    To evaluate both DeLorean and DeeJay, we use two high quality, commercially-released games: a twitch-based first person shooter, Doom3, and a role playing game, Fable3.

    Biography: David Chu is a researcher at Microsoft Research in Redmond where he works on mobile systems with an emphasis on mobile gaming. He is also interested in sensing and context for the mobile OS. His work has appeared in The Verge, Engadget and Wired. David received his Ph.D. and M.S. from the University of California, Berkeley, and his B.S. from the University of Virginia.

    Talk Title: Building Scalable 3D Culture Systems for the Cost-effective Production of Clinical Grade Cells from Human Pluripotent Stem Cells

    Abstract: Building Scalable 3D Culture Systems for the Cost-effective Production of Clinical Grade Cells from Human Pluripotent Stem Cells

    Human pluripotent stem cells (hPSCs), including human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs), have the capacities for indefinite in vitro expansion and differentiation into presumably all cell types in the human body. They therefore represent highly promising cell sources for numerous biomedical applications, such as cell therapy, tissue engineering, drug discovery and toxicity testing. These applications require large numbers of cells of high quality and purity. For instance, ~105 surviving dopaminergic (DA) neurons, ~109 cardiomyocytes, or ~109 β cells are required to treat a patient with Parkinson�s disease (PD), myocardial infarction (MI), or type I diabetes respectively. Analogously, ~1010 hepatocytes are needed for an artificial human liver, and ~1010 cells may be required to screen a million compound library. Considering the large patient populations with degenerative diseases, as well as the millions of chemical/peptide/nucleotide compounds that can be screened against many cell types, massive numbers of hPSCs are thus needed. It is becoming clear that the current 2D-based cell culture systems are incapable of producing sufficient cells with high quality. An attractive approach for scaling up cell production is to move the cell culture from 2D to 3D, and accordingly several 3D suspension systems have been probed for hPSCs production, specifically cell aggregates, cells on microcarriers, and cells in alginate microencapsulates. While these approaches have some attractive aspects, they also highlight significant challenges for 3D hPSC culture including: i) the use of components from human or animal tissue (such as Matrigel, serum, BSA), which limits reproducibility and scalability as well as poses risks for pathogen and immunogen transfer that are problematic for GMP cell production; ii) substantial cell agglomeration that can lead to differentiation and/or death; iii) shear force in agitated cultures that can compromise cell viability; iv) modest cell expansion rates and low cell yields per volume and v) unclear potential for long term serial expansion.

    In this presentation, I will introduce a 3D culture system that utilizes a thermoreversible hydrogel as matrix for versatile and multi-scale hPSC culture. With this simple, defined, scalable, GMP compliant system and protocol that are free of animal derived products, we achieved long-term, high rates of expansion (~20-fold per passage over 5 days, 1072-fold over 280 days, and ~2.0x107 cells/ml gel yield), and high level maintenance of pluripotency (~95%) for multiple hESC and hiPSC lines, all of which offer considerable improvements over the current approaches. Based on this system, we then developed a defined bioprocess for the scalable production of DA neurons from hPSCs for treating PD. We made a small molecule cocktail that can efficiently convert hPSCs into DA progenitors in the 3D hydrogel with a yield of ~8x107 DA progenitors/ml hydrogel and ~80-fold expansion by the end of a 15-day derivation. These cells could survive, mature and function in vivo. I will also present data on using these cells to treat PD in a rodent model. This versatile culture system has the potential to resolve a major challenge that is currently limiting the applications of hPSCs.



    Biography: Dr. Yuguo Lei received his B.S. in chemistry from Peking University in Beijing, China and his M.S. in polymer science at Hong Kong University of Science and Technology, Hong Kong. He then went to UCLA for a M.S. in pharmacology and Ph.D. in chemical engineering before doing his postdoctoral research at UC Berkeley.

    His research interests are to resolve some unsolved human health problems with hPSC-based products. He develops new technologies to address significant challenges that limit the advancement of hPSC-derived cells or products from the benchtop to the bedside. To achieve this goal, he pursues fundamental advances at the intersection of biomaterial design, molecular, cellular and tissue engineering as well as hPSC biology. The resulting technologies are useful for drug discovery, tissue engineering and cell therapies, and Dr. Lei is applying them to treat a number of degenerative diseases, with a focus on the central nervous system.

    Talk Title: Constructing space: how a naive agent can learn spatial relationships by observing sensorimotor contingencies

    Series: CS Colloquium

    Abstract: The brain sitting inside its bony cavity sends and receives myriads of sensory inputs and outputs. A problem that must be solved either in ontogeny or phylogeny is how to extract the particular characteristics within this "blooming buzzing confusion" that signal the existence and nature of physical space, with structured objects immersed in it, among them the agent's body. The idea that spatial knowledge must be extracted from the sensorimotor flow in order to underlie perception has been considered by a number of thinkers, including Helmholtz, Poincare, Nicod, Gibson, etc. However, little work has considered how this could actually be done by organisms without a priori knowledge of the nature of their sensors and effectors. Here we show how an agent with arbitrary sensors will naturally discover spatial knowledge from the undifferentiated sensorimotor flow. The method first involves tabulating sensorimotor contingencies, that is, the laws linking sensory and motor variables. Second, further laws are created linking these sensorimotor contingencies together. The method works without any prior knowledge about the structure of the agent's sensors, body, or of the world. We show that the extracted laws endow the agent with basic spatial knowledge, manifesting itself through perceptual shape constancy and the ability to do path integration. We further show that the ability of the agent to learn all spatial dimensions depends on the ability to move in all these dimensions, rather than on possessing a sensor that has that dimensionality. This latter result suggests, for example, that three dimensional space can be learned in spite of the fact that the retinas are two-dimensional. We conclude by showing how the acquired spatial knowledge paves the way to building the notion of object.

    Talk Title: Human-Centered Computer Security: Beyond the Desktop

    Series: CS Colloquium

    Abstract: Modern technologies are increasingly capable, interconnected, and used in diverse aspects of our lives. Securing these devices is critical: attackers can leverage their properties to perform attacks with novel or amplified harms. It is critical to approach securing these devices from a human perspective in addition to a technical perspective in order to maximize the effectiveness and minimize the repercussions of deployed security systems. I outline a human-centered approach to designing security for these new classes of technologies and ground each step with an example study. First, I use my study on household robots to demonstrate how the properties and usage scenarios of a technology translate into particular threats to users and bystanders. Second, I present how researchers can investigate the characteristics of an application domain in order to inform the design of better security systems, using my work with implantable medical devices as an example. Third, I use my in-situ study investigating the impacts of augmented reality devices on bystander privacy to illustrate how researchers can obtain data on the risks associated with a technology. I conclude my talk with a call for the development of more toolkits to bootstrap the security process, and present one such toolkit: the Security Cards, a physical deck of brainstorming cards that I developed to help computer science students, technologists, and researchers explore the threats that might be posed by a technology system.

    Biography: Tamara Denning is a senior PhD student at the University of Washington working with Tadayoshi Kohno in the Security and Privacy Research Lab. She received her B.S. in Computer Science from the University of California, San Diego in 2007. Tamara's interests are in the human aspects of computer security and privacy, with a focus on emerging technologies. Past areas of work include security for implantable medical devices, the security of consumer technologies in the home, security and privacy issues surrounding augmented reality, and security toolkits for awareness and education.

    Conferences, Lectures, & Seminars


    Speaker: Professor Nader Motee, Lehigh University

    Talk Title: Sparsity Measures in Spatially Distributed Systems

    Abstract: A new theory of compressive feedback control (CFC) design for spatially distributed systems within the areas of distributed control systems, operational research, and machine learning is emerging. The CFC theory asserts that feedback control design for a certain class of spatially distributed systems can be spatially localized using far less sensor measurements than traditional control design techniques. Moreover, the CFC theory exploits the fact that the quadratically optimal state feedback controllers for many real-world systems are sparse and spatially localized in the sense that they have near-optimal sparse information structures. In this talk, I will introduce an important and omnipresent class of spatially distributed systems, so called spatially decaying systems. Examples of spatially decaying systems include spatially distributed power networks with sparse interconnection topologies, multi-agent systems with nearest neighbor coupling structures, arrays of micro-mirrors, micro-cantilevers, and sensor networks. The common fundamental property of all these systems is that there is a notion of spatial distance with respect to which couplings between the subsystems can be quantified using a class of coupling weight functions. Then, I will describe a newly developed mathematical framework, based on notions of quasi-Banach algebras of spatially decaying matrices, to relate spatial decay properties of spatially decaying systems to sparsity features of their underlying information structures. The bridge connecting these two notions is built upon several cornerstones. I will discuss some of the fundamental insights and tools that will allow us to exploit architectural properties of the underlying systems in order to introduce system-oriented sparsity measures for spatially distributed systems.

    Biography: Nader Motee is a P.C. Rossin assistant professor in the Mechanical Engineering and Mechanics Department at Lehigh University. Before joining Lehigh, he was a postdoctoral scholar at the Control and Dynamical Systems Department at Caltech and a visiting scholar at UCSB. He received a PhD degree in electrical and systems engineering from the University of Pennsylvania in 2007. His research interests include theoretical foundation of distributed control systems and optimization with applications to power grid, network of autonomous vehicles, and biological systems. Motee received an AFOSR Young Investigator Award in 2013, the 2008 O.

    Speaker: Diana M. Negoescu, Dept of Management Science and Engineering, Stanford University

    Talk Title: "Dynamic Learning of Patient Response Types"

    Abstract: For many chronic diseases, available treatments are effective only for a subgroup of patients, and biomarkers that accurately assess the responsiveness of an individual patient do not exist. In these settings, information regarding the response type of a patient can only be generated by experimentation -- subjecting the patient to a variety of treatments. Physicians then learn about the response through self-reported patient evaluations, as well as from the (non)occurrence of negative health events such as disease flare-ups. The timing of these events also carries substantial information, which should be taken into account when determining optimal personalized treatments.

    In this talk, I will introduce a continuous-time, two-armed bandit framework that balances the trade-off between exploring alternative treatments and exploiting available information. Unlike most multi-armed bandit models that learn only from observed rewards, our model also incorporates information regarding the frequency of health events, and can be analyzed in closed form to derive guidelines for treatment policies. I will showcase the effectiveness of our methodology by developing an adaptive policy to treat multiple sclerosis, a chronic autoimmune disease. We compare the performance of our policy to that of a standard, non-adaptive treatment policy, and show that, by identifying non-responders earlier, our approach leads to improvements in quality-adjusted life expectancy, as well as significant cost savings. Beyond multiple sclerosis, dynamic learning models that incorporate the timing of events may find several applications in a broader medical decision making context, as a means to design treatment policies for diseases such as depression, rheumatoid arthritis, celiac or Crohn's disease.

    Based on joint work with Kostas Bimpikis, Margaret L. Brandeau and Dan A. Iancu.

    Talk Title: Reducing Losses from Flood-Related Disasters: Dealing with Affordability

    Series: CREATE Monthly Seminar Series

    Abstract: Many residents in flood-prone areas are complaining that they cannot afford to purchase flood insurance because their premiums have been increased significantly due to the passage of the Biggert-Waters Flood Insurance Reform Act of 2012 that mandates risk-based premiums. This goal of this legislation was to reduce the growing deficit in the National Flood Insurance Program (NFIP).

    Due to the above concerns of homeowners in flood-prone areas, Congress is now seriously considering delaying the implementation of this legislation and possible repealing it. I will suggest ways to address the affordability issue by providing means-tested vouchers and incentivizing investments in loss reduction measures using risk-based premiums. The importance of redesigning homes takes on added significance in the face of climate change and sea level rise. Backround paper attached.

    Please RSVP to me (calicchi@usc.edu) no later than Monday, February 24th.

  • NL Seminar- Kenji Sagae:Dependency parsing with directed graph output

    Fri, Feb 28, 2014 @ 03:00 PM - 04:00 PM

    Information Sciences Institute

    Conferences, Lectures, & Seminars


    Speaker: Kenji Sagae, USC/ ICT

    Talk Title: Dependency parsing with directed graph output

    Series: Natural Language Seminar

    Abstract: Most data-driven dependency parsing approaches assume that the structure of sentences is represented as trees. Although trees have several desirable properties from a computational perspective, the structure of linguistic phenomena that go beyond shallow syntax often cannot be fully captured by tree representations. I will describe data-driven dependency parsing approaches that produce more general graphs as output, and present results obtained with these approaches on predicate-argument structures extracted from CCG and HPSG datasets.



    Biography: Kenji Sagae is a Research Scientist in the Institute for Creative Technolgies at the University of Southern California, and a Research Assistant Professor in the USC Computer Science Department. He received his PhD from Carnegie Mellon University in 2006. Prior to joining USC in 2008, he was a research associate at the University of Tokyo. His main area of research is Natural Language Processing, focusing on data-driven approaches for syntactic parsing, predicate-argument analysis and discourse processing. His current work includes the application of these techniques in analysis of personal narratives in blog posts, the study of child language, spoken dialogue systems, and multimodal processing.

  • Integrated Systems Seminar Series - Spring 2014

    Fri, Feb 28, 2014 @ 03:30 PM - 05:00 PM

    Ming Hsieh Department of Electrical and Computer Engineering

    Conferences, Lectures, & Seminars


    Speaker: Sayfe Kiaei, Arizona State University

    Talk Title: On-Chip Power Digital LDO and Isolated Power Management

    Series: Integrated Systems Seminar Series

    Abstract: The first part of this presentation will give a brief overview of research at Connection One on RF, Analog and PMIC. This will be followed by a presentation on Digital Linear Drop-out Regulators and the development of Power Management IC. The development of multi-core highly integrated systems-on-a-chip has created the need for small, fully integrated voltage regulators that operate on a per-core basis. In order to maximize efficiency, most SOC's apply dynamic voltage and frequency scaling (DVFS) on each block of the system to adjust the power based on performance demands. Analog regulators are poorly suited to this task as they are difficult to integrate on sub-micron processes, consume more power, and require precision external capacitors to ensure stability. The development of D-LDO regulators is intended to address these drawbacks of analog regulators.

    Biography: Dr. Sayfe Kiaei is has been with ASU since January 2001. He is a Professor and the Director of the Connection One Center (NSF I/UCRC Center), and Motorola Chair in Analog and RF Integrated Circuits. From 1993 to 2001, he was a Senior Member of Technical Staff with the Wireless Technology Center and Broadband Operations at Motorola where he was responsible for the development of RF & Transceiver Integrated Circuits, GPS RF IC, and Digital Subscriber Lines (DSL) transceivers. Before joining Motorola, Dr. Kiaei was an Associate Professor at Oregon State University from 1987-1993 where he taught courses and performed research in digital communications, VLSI system design, advanced CMOS IC design, and wireless systems. Dr. has published more than 200 journal and conference papers and holds several patents. Dr. Kiaei is an IEEE Fellow and a member of IEEE Circuits and Systems Society, IEEE Solid State Circuits Society, and IEEE Communication Society. Dr. Kiaei has been organizer, on the technical program committee and/or chair of many conferences, including: RFIC, MTT, ISCAS, and other international conferences.

    Talk Title: Diffraction of Elastic Waves Around Layered Strata With Irregular Topography / Seismic Performance of Tilt-Up Structures

    Abstract: First Presenter: Wen-Young Liu

    Diffraction Around an Irregular Layered Elastic Media – Love and Body SH Waves, Rayleigh and Body P-SV Waves are to be investigated by weighted-residual method along with Fourier half-range wave expressions. Diffracted mode shapes and spectral amplification characteristics of Love and Body SH Waves, Rayleigh waves and P-SV-waves at different frequencies are examined and discussed.


    Second Presenter: Yujing Hu
    Title: Performance of Tilt-Up Structures

    Abstract:

    Tilt-up construction is a cost-effective technique which has been widely used in North America, South America and New Zealand. It is estimated that over 15% of all industrial buildings are Tilt-Up in the United States. Although economical to build, this type of structure is vulnerable to strong ground motions. Severe damage to tilt-up structures is reported during past major earthquakes around the world. This research evaluates the effects of moderate and strong ground motions on different types of tilt-up buildings, in order to estimate the potential vulnerability of the structural system. Three dimensional, linear and nonlinear models of three types of tilt-up structures are developed. Nonlinear elements are incorporated for Gluam Beam/Wall connections, Purlin/Wall connections, Panel/Panel connections and roof. Inelastic characteristics for these components are obtained from a series of previous experiments. In addition, cumulative damage of some critical structural components of tilt-up structures is studied by considering low-cycle fatigue problem.
