SUMMARY:ECE PhD Dissertation Defense: Pu Zhao
DESCRIPTION:PhD Dissertation Defense: Towards Robust Image Classification with Deep learning and Real-Time DNN Inference on Mobile \nPu Zhao \nLocation: Zoom Link \nAbstract:  As the rapidly increasing popularity of deep learning\, deep neural networks (DNN) have become the fundamental and essential building blocks in various applications such as image classification and object detection. However\, there are two main issues which potentially limit the wide application of DNNs: 1) the robustness of DNN models raises security concerns\, and 2) the large computation and storage requirements of DNN models lead to difficulties for its wide deployment on popular yet resource-constrained devices such as mobile phones.\nTo investigate the DNN robustness\, we explore the DNN attack\, robustness evaluation and defense. More specifically\, for DNN attack\, we achieve various attack goals (e.g. adversarial examples and fault sneaking attacks) with different algorithms (e.g. alternating direction method of multipliers (ADMM) and natural gradient descent (NGD) attacks) under various conditions (white-box and black-box attacks). For robustness evaluation\, we propose a fast evaluation method to obtain the model perturbation bound such that any model perturbation within the bound does not alter the model classification outputs or incur model mis-behaviors. For the DNN defense\, we investigate the defense performance with model connection techniques and successfully mitigate the fault sneaking and backdoor attacks. With a deeper understanding of the DNN robustness\, we further explore the deployment problem of DNN models on edge devices with limited resources.\nTo satisfy the storage and computation limitation on edge devices\, we adopt model pruning to remove the redundancy in models\, thus reducing the storage and computation during inference. Besides\, as some applications have real-time requirements with high inference speed sensitivities such as object detection on autonomous cars\, we further try to implement real-time DNN inference for various DNN applications on mobile devices with pruning and compiler optimization. To summary\, we mainly investigate the DNN robustness and implement real-time DNN inference on the mobile.

SUMMARY:ECE MS Thesis Defense: Rahul Bathini
DESCRIPTION:MS Thesis Defense: Distributed Containerized Wireless Systems \nRahul Bathini \nLocation: Zoom Link \nAbstract: Future wireless communication paradigms that will form the basis of 5G and beyond architectures will rely on the availability of network infrastructure as a service. In this approach\, the same radio and compute resources are partitioned to serve many users\, each of which may prioritize different performance metrics. Thus\, with the diversity of wireless services and applications\, the current ”one size fits all” network architecture is no longer an option. Indeed\, virtualization incorporates flexibility into the network architecture design to help meet the diverse application/user needs.\nIn this thesis we consider a shared compute resource that must support a number of wireless configuration options. We study the effects of CPU allocation alongside baseband (PHY Layer) configurations such as transmitter gain and Modulation and Coding Schemes (MCS)\, related to various performance metrics of containerized wireless communications systems. We analyze these results and quantify the trends to gain a better understanding of these multiple\, interconnected effects. Finally we propose a controller to provide a user with required QoS from pre-defined Service Set identifiers (SSIDs) given the limited availability of CPU resources. We implement this controller system using open-source baseband software and USRP N310 platforms provided in the COSMOS testbed

SUMMARY:ECE MS Thesis Defense: Hafiyya Malik
DESCRIPTION:MS Thesis Defense: Studies for Improving Multi-channel Confocal Fluorescence Imagining in a Multi-modal Microscope \nHafiyya Malik \nLocation: Zoom Link \nMeeting ID: 988 8423 1362 Passcode: 399185 \nAbstract: The goal of this engineering thesis was to implement confocal fluorescence microscopy in an upgraded legacy electro-optical microscopy system for characterization of the viability of cells in biofilms. This application necessitated a 2-channel fluorescence measurement with the possible addition of confocal reflectance for context. Two major areas were addressed. First was the potential for using a silicon photomultiplier (SiPM) detector to replace the usual vacuum photomultiplier employed in confocal fluorescence microscope. A SiPM development board was purchased and tested to determine its performance at different light levels and in the presence of background light. The SiPM has the potential to be a more robust and reliable detector\, with the one disadvantage of a smaller area than some vacuum photomultipliers. The second area was the alignment of a long optical path that must include optics for complementary modes of imaging and allow for automated measurement across two spectral channels without loss of alignment. Alignment procedures were developed to simplify the process of alignment and a sliding stage was used to maintain alignment of two dichroic filters when changing channels. Based on this work\, multi-channel confocal fluorescence imaging in conjunction with confocal reflectance and bright-field microscope will be possible.

SUMMARY:ECE PhD Dissertation Defense: Apoorve Mohan
DESCRIPTION:PhD Dissertation Defense: Rethinking the Choice between Static and Dynamic Provisioning for Centralized Bare-Metal Deployments \nApoorve Mohan \nLocation: Zoom Link \nAbstract: Technological inertia leads many organizations to continue to employ static provisioning strategies for bare-metal deployments. This results in architectural and runtime inefficiencies. However\, most performance and security-sensitive organizations currently employ static provisioning strategies to run and manage their workloads on physical servers (also known as bare-metal servers). This thesis demonstrates how recent technological advances enable dynamic provisioning strategies to improve aggregate bare-metal resource efficiency in centralized bare-metal deployments. Conceptually\, this dissertation has four parts. First\, it introduces a new system architecture for dynamic bare-metal provisioning. The proposed architecture reduces overhead and operational complexity and improves fault tolerance and performance. To achieve these improvements\, it decouples the provisioned state from the bare-metal servers. Second\, the thesis identifies the performance and operational issues due to intrusive software introspection strategies employed in existing bare-metal deployments. We present a dynamic bare-metal provisioning-based system to enable non-intrusive software introspection of bare-metal deployments to mitigate these issues. Many organizations have realized the cost benefits of consolidating their computing infrastructure over managing multiple\, relatively smaller compute facilities. \nOver the past decade\, virtual infrastructure solutions have become the obvious choice in consolidated (i.e.\, single-tenant managed or centralized) deployments for many organizations due to the scalability\, availability\, and cost benefits it offers. However\, most performance and security-sensitive organizations such as medical companies and hospitals\, financial institutions\, federal agencies run their workloads directly on physical (i.e.\, bare-metal) infrastructure. They are unwilling to tolerate the performance unpredictability and security risks due to co-location and performance overhead or vulnerabilities due to a large code base of the complex virtualization stack. In addition\, even if an organization uses virtual infrastructure\, bare-metal infrastructure is used to set up virtualization software stack and when their workloads require direct and exclusive access to hardware components (e.g.\, InfiniBand\, RAID\, FPGAs\, GPUs) that are difficult to virtualize. Such organizations invest enormous sums of money to buy or rent bare-metal servers and set up and manage bare-metal clusters. Thus\, it is imperative that these organizations efficiently operate and utilize the bare-metal clusters they set up to maximize their investment returns. However\, despite the technological advances over the past decade\, organizations continually employ static provisioning strategies in bare-metal deployments that contribute to poor aggregate bare-metal resource efficiency. Thesis Statement: This thesis demonstrates how dynamic provisioning can mitigate observed inefficiencies in centralized bare-metal deployments. The proposed dynamic provisioning strategies leverages existing storage disaggregation and fault-tolerance technologies to improve aggregate bare-metal resource efficiency. By applying it to four real-world scenarios\, this thesis demonstrates the effectiveness of dynamic provisioning.

SUMMARY:ECE PhD Proposal Review: Keng Chen
DESCRIPTION:PhD Proposal Review: Design of Accurate and Responsive Power Management Integrated Circuits for Microprocessor Systems \nKeng Chen \nLocation: Zoom Link \nAbstract: As technology improves\, the processors used in data centers are becoming increasingly powerful. Since the number of complementary metal-oxide semiconductor (CMOS) transistors integrated into these processors continues to rise\, it becomes more challenging to design the power management integrated circuits to accurately regulate the supply voltages and ensure fast operational speeds for the processors. Furthermore\, with multi-core technology being extensively used in processor design\, there is more than just one voltage rail per chip that needs to be precisely regulated. In this research\, circuit design methods will be developed to improve the regulation accuracy\, both of the output voltage and converter switching frequency\, which are proposed for an integrated buck regulator designed for point of load (POL) applications. In order to ensure both accuracy and fast speed of operation\, a constant-on-time (COT) architecture was selected for this integrated buck regulator design approach. To provide accurate output voltage regulation\, the on-chip feedback sensing network and the bandgap reference circuit need to exhibit high accuracy. For this reason\, a highly accurate bandgap reference generation circuit with 5.8 ppm/°C – 13.5 ppm/°C over a wide operational region (-40 °C to 150 °C) has been designed. This bandgap reference circuit has a current-mode architecture and provides a 1.16V reference voltage with a 3.3V supply. A multi-section curvature compensation method is proposed to alleviate the nonlinear temperature-dependent error from the bipolar junction transistor’s base-emitter voltage. The two operational amplifiers utilized in this bandgap reference design to generate proportional-to-absolute-temperature (PTAT) and complementary-to-absolute-temperature (CTAT) current sources share one auxiliary auto-zero amplifier to ensure low input-referred offset voltage. Within many voltage regulators\, the feedback sensing network consists of multiple operational amplifiers\, and a major error source is the impact of the input-referred offset voltages of these amplifiers. \nThis research introduces the utilization of two different input-referred offset voltage correction methods for multiple amplifiers. The multi-amplifier system under investigation is used for feedback sensing during voltage regulation. It contains an instrumentation amplifier consisting of three folded cascode stages\, and an additional amplifier configured as a unity-gain buffer for a reference voltage. The first method in this work alleviates voltage offsets in a 4-amplifier system based on a shared auxiliary amplifier correction circuit that switches between different target amplifiers. The second method applies a chopping-based auto-zero procedure to cancel the input-referred offset voltage of the same system. Since chopping causes voltage ripples\, a correction circuit with a successive approximation register (SAR) analog-to-digital converter is used to reduce the output ripples. Both proposed methods can achieve less than 1mV feedback sensing error in voltage regulator applications.\nFor the constant-on-time buck regulator itself\, a new frequency locking loop to regulate the on-time pulse is also proposed in this work. The system shows less than 1% frequency shift over a wide programmable operational frequency range (400 KHz to 2 MHz). This frequency accuracy will further benefit the constant-on-time circuit to meet electromagnetic interference requirements without harming the fast-transient performance.

SUMMARY:ECE PhD Proposal Review: Nikita Mirchandani
DESCRIPTION:PhD Proposal Review: Ultra-Low Power and Robust Analog Computing Circuits and System Design Framework for Machine Learning Applications \nNikita Mirchandani \nLocation: Zoom Link \nAbstract: As the scaling of CMOS transistors has almost halted\, performance gains of digital systems have also started to stagnate. There is a renewed interest in alternate computing techniques such as in-memory computing\, hybrid computing\, approximate computing\, and analog computing. In particular\, analog computing has reemerged as a promising alternative to save power and improve performance specifically for machine-learning (ML) applications. Analog computing has better area and power efficiency when compared to their digital counterpart. Power and chip area efficiency make analog computing highly appealing for implementing deep learning algorithms on-chip\, computing circuits for the internet-of-things (IoT) devices\, and implantable and wearable biomedical devices. However\, compared to digital computing\, analog computing methods have not nearly been utilized to their fullest potential due to longstanding challenges related to reliability\, programmability\, power consumption\, and high susceptibility to variations.\nThe subject of this dissertation research is to develop robust ultra-low power analog hardware suitable for machine learning applications. First\, a robust analog design methodology is presented to address issues of variability in analog circuits. A constant transconductance design technique using switched capacitor circuits is presented. The design approach is then applied to build circuits for ML applications. An analog vector matrix multiplier (VMM) is designed to be used in the convolutional layer in an ML analog computing vision hardware platform. Computing circuits are tested as part of an image classification DNN algorithm on the MNIST dataset and can achieve a classification accuracy of 96.1%. \nThe design approach is also used to design an analog computing system architecture for detection of seizures using EEG signals. A conventional EEG monitoring system includes an analog front-end (AFE)\, ADC\, digital filtering stage\, EEG feature extraction engine\, and SVM classification. Such systems suffer from high power and chip area requirements. The corresponding analog architecture is composed of AFE amplifiers to provide gain for the incoming signal. The AFE is followed by an analog filtering stage\, where spectral power from each of the bands is used as a feature for seizure classification. The output of each filter is applied to a corresponding feature extraction circuit to continuously monitor the onset of a seizure in an ultra-lower power mode with sub-threshold analog processing. The system level architecture is first modeled to obtain classification accuracy of seizures. Simulation times for the design of such complex analog systems can be prohibitively long\, particularly when the impacts of nonidealities such as noise\, nonlinearity\, and device mismatches have to be considered at the system level. The simulation time is reduced by building accurate models of the analog blocks for faster simulations. The analog models help to define the required specifications for each block in order to achieve a specified system-level classification accuracy.\nInfrastructure circuits like oscillators and voltage regulators for the proposed SoC are presented. A 254 nW 21 kHz on-chip RC oscillator with 21.5 ppm/oC temperature stability is presented to provide stable clock source for the proposed SoC.

SUMMARY:ECE PhD Dissertation Defense: Wenqian Liu
DESCRIPTION:PhD Dissertation Defense: Explainable Efficient Models for Computer Vision Applications \nWenqian Liu \nLocation: Zoom Link \nAbstract: State of the art deep learning based models\, such as Convolutional Neural Networks (CNNs) and generative models\, achieve impressive results\, but with their great performance comes great complexity and opacity\, huge parametric spaces and little explainability. The criticality of model explainability and output interpretability\, manifests clearly in real-time critical decision making processes and human-centred applications\, such as in healthcare\, security and insurance. Explainability and interpretability are tackled in this thesis\, as intrinsic qualities in the model architecture as well as post-hoc improvement on existing models. In the area of frame prediction in video sequences\, we introduce DYAN\, a novel network with very few parameters\, that is easy to train and produces accurate high quality predictions. Another key aspect of DYAN is interpretability\, as its encoder-decoder architecture is designed following concepts from systems identification theory and exploits the dynamics-based invariants of the data. We also introduce KW-DYAN\, an extension of DYAN that tackles the issue of time lagging in video predictions\, by implementing a novel way of quantifying prediction timeliness and proposing a new recurrent network for adaptive temporal sequence prediction. The experimental results show the reduced lagging across datasets\, while also performing well in other metrics. In this thesis we also propose the first technique to visually explain VAEs by means of gradient-based attentions\, with methods to generate visual attentions from the learned latent space\, and also demonstrate such attention explanations serve more than just explaining VAEs. We show how these attention maps can be used to localize anomalies in images\, conducting state-of-the-art performance on multiple datasets. We also apply our technique for skin image anomaly detection and diagnosis and achieve competitive quantitative and qualitative results.

SUMMARY:ECE PhD Dissertation Defense: Vageeswar Rajaram
DESCRIPTION:PhD Dissertation Defense: Near-Zero Power Microelectromechanical Sensors for Large-Scale IoT Sensor Networks \nVageeswar Rajaram \nLocation: ISEC 432 \nAbstract: The Internet-of-things revolution has ushered the development of sensing technologies aimed towards establishing large-scale remote sensor networks to monitor the environment continuously and with high spatial resolution. However\, with existing sensor technologies this goal has so far been limited in terms of scalability (i.e.\, the number of sensors in a network\, areal coverage and spatial granularity). A major impeding factor is sensor power consumption: state-of-the-art remote sensor technologies need to be actively powered (i.e.\, by a battery) to continuously monitor the environment for an object of interest\, even at standby (when it is not present). This is because all signals collected by the sensor from the environment need to be processed by active signal conditioning circuits to distinguish a signal of interest from other signals. Therefore\, in applications where an event or signal of interest occurs only occasionally\, most of the battery is drained by processing irrelevant signals. The result is that as the sensor network scales up\, so do the costs and labor associated with the sensors’ battery replacements. This makes it unfeasible to deploy and maintain large numbers of sensors for any application and greatly limits the scale of sensor networks. Extremely low power consumption therefore is critical in enabling large sensor networks by reducing or even eliminating costs associated with frequent battery replacements.\nThis work describes the development of a revolutionary new sensing platform aimed at creating sensors with battery lifetimes limited only by the self-discharge of the battery itself (>10 years). The ultimate goal for the technology is to enable maintenance-free sensor nodes for truly large-scale “deploy-and-forget” sensor networks. In particular\, this work details the development of novel infrared sensors based on micro-electro-mechanical photoswitches that are capable of detecting and distinguishing specific infrared signatures associated with objects of interest (hot gases\, fire\, human body\, etc.) while remaining dormant with near-zero power consumption at standby. This unique sensor technology aims to break the paradigm of requiring a power supply to perform sensing by instead relying on the energy contained in the infrared signals emitted by the object of interest itself to perform its detection. This dissertation presents a comprehensive summary of the sensor’s design\, its capabilities\, and the various technical developments that have led this technology to evolve from a concept to a prototype near-zero power wireless infrared sensor with orders of magnitude lesser power consumption compared to the state-of-the-art.

SUMMARY:ECE PhD Proposal Review: Nirjhar Bhattacharjee
DESCRIPTION:PhD Proposal Review: Sputtered Topological Insulator/Ferromagnet Heterostructures for Energy Efficient Spintronic Device Applications \nNirjhar Bhattacharjee \nLocation: Zoom Link \nAbstract: Topological insulators (TI) are Van der Waals (VdW) layered materials which possess enormous spin-orbit coupling (SOC) strength and spin-momentum locked robust surface states. TIs in presence of time-reversal symmetry breaking magnetic order can also exhibit chiral quantum anomalous (QAH) or Axion insulator edge channels. These and myriad of other material properties predicted\, and achievable utilizing TIs\, magnetic-TIs (MTI) and TI based heterostructures can open the path towards realization of a diverse class of energy efficient spintronic devices for information processing and storage. Crystalline oriented TIs which possess topologically nontrivial properties are grown using molecular beam epitaxy (MBE) which is incompatible with industrial CMOS processes. Magnetron sputtering\, on the other hand is the CMOS industry stand thin film growth technique because of the advantages of high throughput\, large area\, and high quality thin film growth capability. In this work\, first the growth of high quality TI: Bi2Te3 thin films using CMOS compatible magnetron sputtering process is introduced. Next\, room temperature characterization of magnetic and SOT properties of TI/ferromagnet (FM) heterostructures will be presented. Finally\, fascinating magnetic properties of material systems with FM species intercalated in TIs will be reported which can possibly house exotic quantum material phases. \nBy varying process temperature between 20-250ºC\, growth of Bi2Te3 with stoichiometric composition and varying crystalline order from disordered to highly c-axis oriented VdW layered films were obtained. Using X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM) imaging\, the crystalline property of the TI film was confirmed. Further\, coupling the sputtered TI films with ferromagnetic (FM) thin films surprisingly showed a giant enhancement in Gilbert damping with c-axis oriented TI which is crucial for energy efficient SOT-MRAM devices. This suggested enhancement in spin-orbit coupling strength for c-axis oriented TI thin films compared to disordered ones. Formation of interface layers because of elemental diffusion has been reported in literature. But\, literature reports on SOT characteristics have largely assumed atomically sharp interfaces between TI and FM layers. We observed crystalline order dependent interface thickness and composition in Bi2Te3/Ni80Fe20 heterostructures because of diffusion of Ni across the interface. An enhancement in damping-line SOT in crystalline ordered Bi2Te3 was observed. The spin-charge conversion efficiency was however found to be larger for granular and lowest for polycrystalline disordered Bi2Te3 samples considering the interface layers. Further\, with the intercalation of Ni in Bi2Te3\, emergence of an antiferromagnetic VdW phase was observed in Ni-intercalated Bi2Te3 interface. This AFM VdW interface resulted in a large spontaneous exchange bias in Bi2Te3/Ni80Fe20 and Bi2Te3/NiZn-Ferrite heterostructures at temperatures below ~63 K which is higher than the transition temperatures of MTIs reported in literature. Structural and chemical characterization of the Ni-intercalated Bi2Te3 showed evidence of formation of Ni-Te bonds and indicated towards formation of MTI compounds. These results open new avenues for experimental exploration of fascinating high-temperature QAH and other topologically nontrivial material phases in interfaces of industrial CMOS process compatible sputter-grown TI/FM heterostructures. Understanding the properties of these TI based material systems can lead to realization of robust energy efficient spintronic devices.

SUMMARY:Distinguished Lecture: Dr. Elliot Eichen
DESCRIPTION:The Institute for the Wireless Internet of Things is pleased to host a distinguished lecture on Real-time Geo-spatial Spectrum Sharing by Dr. Elliot Eichen. \nWhen: Monday\, September 20th\, 1pm. \nLocation: Zoom Link \nAbstract: New technology and new applications for wireless communications have created competition for frequency bands traditionally allocated to remote sensing and defense applications. Competition for spectrum is particularly intense in mm (and sub-mm) wave bands where the requirements for 5G/6G transmissions overlap with measurements made by passive radiometers (Earth Exploration Satellite Services – EESS) that are used for weather forecasting and as baseline data for climate models. Real-time Geospatial Spectrum Sharing (RGSS) enables EESS radiometers and 5G/6G networks to gracefully share spectrum by modifying network traffic during the time window (~ 10s of msec) that a base station (gNB) and its connected endpoints (UEs) are within the effective field of view (eFOV) of a radiometer. RGSS is based on existing network infrastructure rather than Monte-Carlo network simulations (the ITU model); it can provide better isolation between 5G/6G transmissions and EESS radiometers than the ITU’s hardware-based Out-of-Band (OOB) emission limits (e.g.\, -32 dBW/200MHz-gNB and -29 dBW/200MHz-UE) in dense urban environments\, while simultaneously enabling carriers to create larger cell sizes and use network repeaters in suburban and rural settings. In addition\, RGSS can adapt to changes in network or remote sensing technology by modifying the underlying network or EESS ecosystem descriptions (schemas). \nIn this talk\, we show that RGSS: \n\nCan prevent 5G/6G transmissions from corrupting EESS measurement data\nHas sufficient geolocation accuracy to provide a realistic solution\, based on experimental confirmation of predicted measurement pixels vs. actual measurement pixels\nApplies to all mm-wave and submm-wave bands (e.g.\, a single system can be used for all bands\, such as 24\, 51\, and 90 GHz\, although the modification time windows for each band may be different)\nEnables carriers to optimize network performance by geography and time of day\, rather than designing for the worst-case scenario across the entire network (i.e.\, avoids the ” one size fits all” OOB emissions model)\nIncludes the effect of massive Multiple-Input Multiple-Output (MIMO) beamforming antennas\nIs commensurate with existing 5G architectures and deployment models\, and\nProvides a simple mechanism to test and police compliance compared with over the air TRP OOB measurements.\n\nBio: Elliot Eichen retired as Director of R&D at Verizon in 2017\, after a 35-year career (except for 2½ years on staff at MIT) at GTE Labs\, GTE/BBN\, and Verizon Labs. From 2018-2019\, he was an IEEE-USA/AAAS congressional fellow\, which is where he became interested in spectrum management and the overlap between 5G/6G and EESS passive sensors. Dr. Eichen received a Ph.D. in Optics from The University of Arizona\, and a B.S in Physics from SUNY Stony Brook. His contributions to the technical community include associate editor of IEEE Photonics Technology Letters\, committee chair of Optical Fiber Communications (OFC)\, chair of the IEEE/OSA Optical Amplifier Conference\, Visiting Industry Professor at Tufts University\, and adjunct faculty at NEU. He has more than 40 peer-reviewed publications and about 60 US patents.

SUMMARY:ChE Seminar Series: Materials Innovation in Nanotechnologies
DESCRIPTION:ChE Seminar Series Presents: \nDr. Paulette Clancy\, Ph.D\nHead of the Department of Chemical and Biomolecular Engineering at Johns Hopkins University \nMaterials Innovation in Nanotechnologies \nAbstract\nThere are many problems at the forefront of materials chemistry whose solution is stymied by its inherent complexity. Such problems are characterized by a rich landscape of parameters and processing variables that is combinatorially too large for either an experimental or a computational approach to solve through an exhaustive search. In such cases\, the usual approach is an Edisonian trial-and-error approach\, which inevitably leaves areas of parameter space unexplored. The problems that we have explored are also characterized by a scarcity of data\, since the data are expensive to acquire\, both experimentally and computationally. This makes it an ideal candidate to solve using a Bayesian optimization (BayesOpt) approach.\nWe have used a Bayesian approach to study several problems in self-assembly processes involving materials chemistry. This talk will discuss two mature test cases in which we used BayesOpt extensively to study (1) how to optimize the choice of solvent and halides to produce high quality thin films of lead-based hybrid organic-inorganic perovskites and (2) identify stable and metastable polymorphs of an organic semiconducting material. I will end with some ideas of where the BayesOpt field can expand its use in the chemical sciences and share some “lessons learned” in implementing BayesOpt and machine learning\, which may be helpful to others who decide to start adding machine learning to their research repertoire. \nBiography\nPaulette Clancy is a Professor and the inaugural Head of the Department of Chemical and Biomolecular Engineering at Johns Hopkins University. She is also the Samuel and Diane Bodman Professor Emerita of Chemical Engineering at Cornell. She is the Associate Director of the Hopkins Center for Integrated Structure-Materials Modeling and Simulation. She was the inaugural Director of the Cornell Institute for Computational Science and Engineering for almost 10 years and is reprising a similar role at Hopkins\, chairing our petascale research computing resources\, ARCH.\nHer research group is recognized as one of the country’s leading computational groups in atomic- scale modeling of materials and algorithm development. Her current thrust is to develop machine learning algorithms to accelerate the search for optimal materials processing protocols. Her group has always been focused on electronic materials\, but it also includes more esoteric projects include xenobiology (Life on Titan) and a screening of therapeutic oligomers to maximize antibacterial ability. She has won numerous awards for mentoring\, service learning and civic engagement\, and promoting those from under- represented groups.

SUMMARY:ECE PhD Proposal Review: Tianyu Dai
DESCRIPTION:PhD Proposal Review: Data-Driven Control and Estimation \nTianyu Dai \nLocation: Zoom Link \nAbstract: During the last two decades\, data-driven control (DDC) has attracted growing attention in the control community. Unlike model-based control (MBC) that first uses the collected data to identify the system\, then designs the controller according to the certainty equivalence principle\, DDC skips the system identification (SYSID) step and leads to a control law directly from data. One important feature of DDC is that some fundamental limitations of MBC such as uncertainty versus robustness\, inevitable modeling error\, and possible expensive cost of SYSID are avoided in the DDC framework. These benefits enable the researcher to design controllers with better performance and accuracy. \nThe aim of this proposal is to summarize our contributions to the DDC field. We mainly discuss the following problem: given a single trajectory of noisy data and a few priors of the model structure\, how to design a state feedback controller to stabilize the system with unknown dynamics and in addition\, to meet some performance criteria. The main idea hinges on duality theory to establish the connection between two sets\, one compatible with the noisy data\, and the second satisfying some design properties such as stability or optimality. Our main results show that for all possible systems compatible with the data\, the data-driven control law can be obtained by solving a convex optimization problem. \nThis proposal is organized as follows: to start with\, we propose a DDC framework for switched linear systems relying on the Farkas’ lemma to search for a common polyhedral control Lyapunov function using the theory of moments. Then to reduce the computational burden\, we provide another method called data-driven quadratic stabilization control for linear systems that is based on quadratic Lyapunov function. To deal with nonlinear system\, we first design data-driven controllers for polynomial systems using the dual Lyapunov theorem. Then to handle general nonlinearities\, we propose a method based on state-dependent representations. Finally\, a data-driven estimator is proposed that gives the worst-case optimal estimation of the trajectory of a switched linear system.

SUMMARY:ChE Seminar Series: Learning about Biological Interactions\, Recognition\, and Targeted Delivery Through Surface Forces
DESCRIPTION:ChE Seminar Series Presents: \nDr. Tonya Kuhl \nProfessor and Chair\, Department of Chemical Engineering\, UC Davis \nLearning about biological interactions\, recognition\, and targeted delivery through surface forces \nAbstract: \nThe promoters of cell adhesion are ligands\, which are often attached to semi-flexible tethers that bind to surface receptors on adjacent cells. Drug delivery systems\, such as Stealth Liposomes\, have also attempted to use biological specificity to target therapeutic payloads. Using a combination of Monte Carlo simulations\, diffusion reaction theory\, and direct experiments (surface force measurements)\, we have quantified how polymer tethers alter the interaction and binding/capture based on biospecificity (ligand-receptor binding). Experimental and theoretical results as a function of molecular weight and bi-modal distributions will be discussed to enable rational design. \nBiography: \nTonya Kuhl\, is Professor and Chair of Chemical Engineering\, the co-Director of the UC Davis Coffee Center (and co-instructor and developer of ECH 1 “The Design of Coffee”)\, and a faculty member of the Biophysics and Biomedical Engineering Graduate Groups. Her Bachelors was from the University of Arizona and Ph.D. from UCSB\, both in chemical engineering. Her research interests are in the general area of colloidal science\, self-assembly\, and complex fluids.  In particular\, the Kuhl group studies a wide range of systems from surfactants\, lipids and proteins to polymer coatings\, nanoparticles and confined fluids. The common theme is that “interfaces are where stuff happens”.  Her group studies interfaces by directly measuring the normal interactions (attractive and repulsive) between surfaces and their lateral friction using specialized high resolution force spectroscopy. Complementary x-ray and neutron scattering measurements are used to measure the exact film structure on a molecular level\, enabling a fundamental understanding of how surface film structure and experimental conditions yield the measured properties.  Rather than more empirical\, “guess and test”\, approaches for improvement in properties or functionality – the Kuhl group uses direct measurements and theory to enable predictive modeling and rational design.
