SUMMARY:ECE PhD Dissertation Defense: Kai Li
DESCRIPTION:PhD Dissertation Defense: Reconfigurable and Intelligent Wireless Charging Surfaces \nKai Li \nLocation: 232 ISEC \nAbstract: Reconfigurable intelligent surfaces (RISs) have received significant attention for theirpotential to transform the environments by intelligently reconfiguring the surfaces\, infrastructures\,and engineering the electrical and magnetic fields. On the other hand\, while wireless power transfer has advanced\, there has been limited progress on increasing the charging coverage\, such as charging over large surfaces\, multi-device charging\, and automation. This dissertation aims to address these challenges and design and develop first-of-its-kindtheory and practice to transform ordinary surfaces into contactless\, intelligent\, and multi-devicewireless chargers. First\, the combination between magnetic resonance and the so-called concept of‘energy hopping’ across wireless inter-connected coils turns a large surface into a programmablewireless charging surface. The magnetic fields are carefully shaped on the fly over the surface\,enabling them to distribute energy efficiently at multiple locations on demand and charge differenttypes of devices. Two frameworks are developed: SoftCharge can deliver 23 W up-to 20cm over a larger surface\, and iSurface enables the creation of arbitrary and configurable power spots and power flow paths over 2D and 3D resonator surfaces. Inspired by the strong coupled magnetic resonance wireless power transfer\, two intelligentsurface sensing frameworks\, SoftSense\, and iSense\, are introduced that create collaborative surface-based object sensing and tracking using networked coils. SoftSense allows detection of the type of object and where it is placed on a large surface. iSense enables robot tracking over large surfaces.We validate our design on real sensing prototypes\, and experimental results show that each sensing coil only consumes few milliwatts and has 90% accuracy for velocity estimation.Combined with meta-surface\, we extended the intelligent charging surfaces to enhances safety\, end-to-end power transfer efficiency\, and customized power pattern over the surface.Toward this\, we design and develop a new system call meta-resonance wireless power transfer system that consists of power distribution layer and meta-resonance layer\, along with a new theory and prototype for fine-tuned and controllable power amplifying\, power blocking and normal power passing over the surface. We aim to create customized pattern and different application from portable devices(phone\, tablet) to medical devices\, and industrial devices with high safety and high power transfer efficiency.

SUMMARY:ChE Seminar Series: Orchestrating Cellular Regeneration at Organ Scale
DESCRIPTION:ChE Seminar Series Presents: \nYvon Woappi\, Ph.D. \nK99/R00 MOSAIC Fellow at Harvard Medical School\, Brigham and Women’s Hospital \nAbstract \nLarge scale tissue damage\, such as organ failure and burn injury\, is a leading cause of morbidity and death. However\, the mechanisms underlying full regeneration of organs remain poorly understood. As the largest organ system in the body\, the integumentary system is a composite tissue evolutionarily adapted for healing. Consequently\, its complex physiology requires multifaceted cooperation between several distinct cell populations and cell lineages of embryologically distinct origins. Equally integrated within this dynamic process is local immune response that produces mitogenic and inhibitory signals throughout the restoration procedure. There remains a significant gap in understanding how these processes are orchestrated\, and how various skin cell populations from distinct developmental lineages functionally cooperate to regenerate tissue at organ scale. My research seeks to characterize the molecular language of tissue healing and to harness this malleable dialect for the regeneration of mammalian tissues. Through the development of organoid models of wound regeneration\, and the coupling of these systems with novel gene-editing approaches\, my work is enabling the functional understanding of the multifaceted cellular events executed throughout restorative healing. This seminar will describe these high throughput technologies and will illustrate their utility in identifying novel regulators of tissue healing. \nBio \nDr. Yvon Woappi’s passion for life sciences ignited during his childhood in Douala\, Cameroon and was magnified after his family immigrated to Hanover\, Pennsylvania during his middle school years. He went on to receive his B.S in Biology at the University of Pittsburgh\, and his Ph.D. in Biomedical Sciences as a Grace Jordan McFadden Fellow under Lucia Pirisi at the University of South Carolina. There\, he developed a 3D skin organoid system to study the relationship between epithelial regeneration and virus-induced neoplasia. He subsequently completed postdoctoral training in the Harvard Dermatology Research Training Program at Brigham and Women’s Hospital where he established novel in vivo gene editing systems to understand the contribution of distinct cell lineages in tissue regeneration and cancer. He was recipient of the 2019 Engineering the Genome Award\, and was later selected as a Rising Star in biomedical sciences and engineering by MIT\, Cornell\, BU and Columbia University. Most recently\, Dr. Woappi was awarded the NIH K99/R00 MOSAIC award to launch his independent research career. Away from the bench\, he is an ardent proponent of inclusive excellence and currently sits on the advisory committee for the NIH Continued Umbrella Research Experiences Program at Harvard Medical School.

SUMMARY:ECE PhD Dissertation Defense: Flavius Pop
DESCRIPTION:PhD Dissertation Defense: Intrabody Communication for Real-Time Monitoring of Implanted Medical Devices based on Piezoelectric Micromachined Ultrasonic Transducers \nFlavius Pop \nLocation: Zoom Link \nAbstract: Nowadays when we think about medical devices and patient monitoring\, we can easily imagine ourselves laying down in a hospital bad\, wires coming out of everywhere\, and being looked after by nurses and physicians. Scary and not that comfortable! For this reason\, medical wearable devices are becoming more popular for at-home monitoring and transmitting data back to the hospital. Sometimes wearables are not enough\, this is why Implanted Medical Devices (IMDs) are still required to monitor many vital signs (blood flow\, insulin level\, neurons reading etc.) and act upon these readings (nerve stimulation\, heart defibrillation\, insulin pumping etc.). In order to be minimally invasive\, reduce the risk of infection and rejection from the body\, and last a long time (avoiding any further surgery) the IMDs require robust wireless communication technology to communicate with the external world. In this presentation I am going to show how we can implement an ultrasonic wireless communication link based on Piezoelectric Micromachined Ultrasonic Transducers (pMUTs) arrays. PMUT arrays can be integrated with existing IMDs\, used for wireless power charging\, and can enable communication links for receiving and transmitting data. During the first part of the presentation I will show the modeling and design of the pMUT arrays\, followed by the fabrication process and the device’s characterization for system level validation. At this point\, the communication link is implemented with arrays implanted in a tissue phantom and the channel is characterized at several distances. During the second part of the presentation I will show novel techniques to improve the ultrasonic communication link such as duplexing matching networks for bandwidth definition and direct modulation for implantation depth increase and direct bitstream feeding. In the future I envision that the number of IMDs are going to increase\, and therefore I developed a scanning protocol that will allow medical doctors to find all implanted devices. This is the equivalent of an “ultrasonic stethoscope”. Given the small form-factor of the IMDs these will have little to no space for a battery\, limiting the operation lifetime. For this reason\, I developed an Ultrasonic Wakeup Receiver (UWuRx) based and on the direct modulation system and on a Micromachined Electro-Mechanical System (MEMS) switch which allows for near zero-power consumption in the idle state. This UWuRx enabled on-demand device usability and limited the idle power consumption\, which leads to battery life extension.

SUMMARY:ECE PhD Proposal Review: Zulqarnain Qayyum Khan
DESCRIPTION:PhD Proposal Review: Interpretable Machine Learning for Affective Neuroscience and Psychophysiology \nZulqarnain Qayyum Khan \nLocation: Zoom Link \nAbstract: In this thesis\, we leverage Machine Learning to investigate questions of interest in affective psychophysiology and neuroscience . We argue for and apply appropriate existing methods where possible and analyze the results they provide. Where existing methods fail to provide an answer we propose and build new models. We demonstrate the use of Hierarchical Clustering to investigate autonomic nervous system reactivity during an active coping stressor task\, revealing physiological indices of challenge and threat. Similarly\, we leverage Dirichlet Process Gaussian Mixture Modelling (DP-GMM) to reveal the variation in affective experience during a context-aware experience sampling study and to investigate the relationship between emotional granularity and cardiorespiratory physiological activity using resting state data for participants in the same study. We propose and develop Neural Topographic Factor Analysis (NTFA)\, a novel factor analysis model for fMRI data with a deep generative prior that teases apart participant and stimulus driven variation and commonalities and learns a latent space that can shed light on important neuroscientific phenomenon such as individual variation and degeneracy.\nBased on the work we have already done\, we propose three further lines of research that we intend to include in this thesis. First\, NTFA can essentially be viewed as a family of models\, where appropriate modifications can be made depending on what questions are needed to be answered. Leveraging this\, we propose explicitly adapting NTFA to tackle the question of degeneracy in neural responses. This involves introducing another latent space which can be used to capture and visualize the interaction of each participant with each stimulus in a given fMRI study. The arrangement of inferred embeddings in this latent space can then suggest presence or absence of different types of degeneracy in neural responses among participants in response to the presented stimuli. Second\, during the course of this interdisciplinary research we realized that there is a need for a comprehensive work that sheds light on the assumptions and limitations of some of the most popular machine learning methods used commonly in the sciences (specially psychology)\, and provide recommendations on how researchers can be more mindful of the underlying assumptions machine learning methods make. This can then equip users of ML methods to draw more appropriate conclusions from the results they get. We intend to include this in our thesis. Third\, continuing along the same lines\, there is also a need for better explanation models for the increasingly complicated ML models in use today. This is especially true in health sciences where the knowledge of why an ML model made a particular decision is almost as important as that decision being accurate. To this end we propose a theoretical work that ties the reliability of explanation models to the robustness of the models they are trying to explain.

SUMMARY:ECE PhD Proposal Review: Tong Jian
DESCRIPTION:PhD Proposal Review: Robust Sparsified Deep Learning \nTong Jian \nLocation: Zoom Link \n(ID: 75807284369\, Passcode: 463BXOZk) \nAbstract: In this thesis\, we investigate and address robustness concerns about DNN-based real-life applications on resource constrained systems\, environment adaptation\, and adversarial learning\, respectively. We propose a means of compressing a Radio Frequency (RF) deep neural network architecture through weight pruning\, and provide a systems-level analysis of the implementation of such a pruned architecture at resource-constrained edge devices. In particular\, we jointly train and sparsify neural networks tailored to edge hardware implementations. Under only negligible accuracy loss (less than 1%)\, we can achieve at most 27.2x pruning rate for 50-device classification. We demonstrate the efficacy of our approach over multiple edge hardware platforms and our method yields significant inference speedups\, 11.5x on the FPGA and 3x on the smartphone\, as well as high efficiency.\nFurthermore\, we propose a new learn-prune-share (LPS) algorithm for achieving robustness to environment adaptation in the field of lifelong learning. Our method maintains a parsimonious neural network model and achieves exact no forgetting by splitting the network into task-specific partitions via an ADMM-based weight pruning strategy. Moreover\, a novel selective knowledge sharing scheme is integrated seamlessly into the ADMM optimization framework to address knowledge reuse. We show that our approach achieves significant improvement over the state-of-the-art methods on multiple real-life datasets.\nFinally\, we investigate the HSIC bottleneck as regularizer (HBaR) as a means to enhance adversarial robustness. We show that the HSIC bottleneck enhances robustness to adversarial attacks both theoretically and experimentally. In particular\, we prove that the HSIC bottleneck regularizer reduces the sensitivity of the classifier to adversarial examples. Our experiments on multiple benchmark datasets and architectures demonstrate that incorporating an HSIC bottleneck regularizer attains competitive natural accuracy and improves adversarial robustness\, both with and without adversarial examples during training.

SUMMARY:ECE PhD Dissertation Defense: Murphy Wonsick
DESCRIPTION:PhD Dissertation Defense: Supervisory Control for Humanoid Robots Through Virtual Reality Interfaces \nMurphy Wonsick \nLocation: ISEC 655 \nAbstract: Recent advancements in robotics have allowed robots to become capable enough to be used in a wide variety of domains that are dangerous for humans to operate in\, such as disaster relief operations\, exploration of extraterrestrial planets\, bomb disposal\, or nuclear decommissioning efforts. However\, current supervisory control interfaces that allow humans to explore and interact in these environments through remote presence and teleoperation are complex and often require expert operators. Virtual reality provides a medium to create immersive and easy-to-use teleoperation interfaces. Virtual reality allows operators to visualize and interact with 3D data in a 3D environment that is not possible with traditional interfaces that make use of 2D devices\, such as monitors\, keyboards\, mice\, tablets\, and/or game controllers. Yet\, development of supervisory control virtual reality interfaces for robot operation is still very limited. Most present work in virtual reality interfaces focuses on direct teleoperation and not on high-level control that supervisory control interfaces can provide. In this dissertation\, we focus on developing virtual reality supervisory control interfaces for remote robot operation. We specifically focus on high degree-of-freedom robots\, such as humanoid robots or mobile manipulator robots\, as they are the most suited types of robots for remote operation. To accomplish this\, we first look to better understand and define humanoid robot capabilities using NASA’s humanoid robot\, Valkyrie. Following\, we synthesize the current state-of-the-art supervisory control interfaces for humanoid robots to create our own supervisory control interface using traditional devices. We then use this information to create a virtual reality supervisory control interface for Valkyrie. Finally\, we look to improve virtual reality interfaces for robot operation through a user-centered design approach to inform future development on virtual reality interfaces.

SUMMARY:ECE PhD Dissertation Defense: Mehdi Nasrollahpourmotlaghzanjani
DESCRIPTION:PhD Dissertation Defense: RFICs for Biomedical Magnetic and Magnetoelectric Microsystems \nMehdi Nasrollahpourmotlaghzanjani \nLocation: Zoom Link \nAbstract: Design and analysis of the advanced biomedical circuit and systems in wide variety of applications has emerged a significant interest. Not only in different engineering disciplines\, but also in a variety of applications such as neuroscience\, COVID-19\, etc. In this study\, we are proposing an implantable device\, handheld device for detecting different diseases and the RFIC design for the ME antenna and passive devices and sensor evaluations to diagnose different diseases.\nFirst\, we show a miniaturized implantable device for deep brain implantation that provides wireless power transfer efficiency (PTE) of 1 to 2 orders of magnitude higher than the reported micro-coils for brain stimulation. The proposed device will simultaneously measure the as magnetic field activity when neurons are firing. The proposed rectangular ME antenna wireless power transfer efficiency is 0.304 %\, which is considerably higher than that of micro-coils. Measurements results show that the maximum achievable power transfer of a ME antenna outperforms that of an on-silicon coil by approximately 7 times for a Tx-Rx distance of 0.76 cm and 3.3 times for a Tx-Rx distance of 2.16 cm.\nIn the second part we will go over the RFIC design for the bio-implant devices\, evaluation of the ME antennas for communication purposes and the circuit interface to measure the ME and GMI sensors. A low-noise amplifier (LNA) topology with tunable input matching and noise cancellation utilized in a Bluetooth receiver frontend is introduced and described in this study\, which was designed and optimized to interface with a magnetoelectric (ME) antenna in a 0.35 µm MEMS-compatible CMOS process. Input matching at the LNA-antenna interface is controlled with a circuit that varies the effective impedance of the gate inductor using a control voltage. Tunability of 455 MHz around 2.4 GHz is achieved for the optimum S11 frequency with a control voltage range of 0.3 V to 1.2 V. Besides\, a miniaturized CMOS oscillator using microelectromechanical system (MEMS) resonating at 159 MHz frequency is designed and simulated to drive ME sensors. The proposed oscillator provides a phase noise as low as -131.3 dBc/Hz at 10 kHz and -137.9 dBc/Hz at 100 kHz offset frequencies while consuming 2.24 mW power.\nFor final part\, we will discuss the handheld device design for early diagnosis of different diseases such as\, lung cancer\, Alzheimer\, Covid-19\, etc through exhaled breath on the molecularly imprinted polymer (MIP) gas sensors. A novel gas sensor has been developed that might be applied to diagnose Covid-19 from the exhaled breath instantly. The handheld device is designed to read the sensor activities and send the data to the android phone to show if the patient is at risk or not. For this purpose\, a lock-in amplifier is designed to read the resistance in ac domain and transmit the digitized data through Bluetooth communication link.

SUMMARY:ECE PhD Dissertation Defense: Sara Banian
DESCRIPTION:PhD Dissertation Defense: Content-Aware AI-Driven Design Assistance Frameworks for Graphic Design Layouts \nSara Banian \nLocation: Zoom Link \nAbstract: Designing user interfaces (UIs) for mobile interaction is widespread but still challenging. It is important for the overall user satisfaction and application success. During the design process\, designers express their requirements through images describing the UI’s layout\, structure\, and content. Designers\, however\, encounter key challenges throughout the design process. For example\, searching for inspiring design examples is challenging because current search systems rely on only text-based queries and do not consider the UI structure and content. Furthermore\, these systems often focus on overall page-level layout over individual UI components. Also\, creating wireframe templates is difficult for many designers as it necessitates an understanding of different design guidelines. Therefore\, it is critical to support designers by developing effective design tools to help them be more productive and creative.\nIn this dissertation\, I aim to explore how to develop design assistance methodologies to augment the process of UI layout design\, with a particular focus on visual search and layout generation. Specifically\, for this exploration\, I seek to investigate the use of advanced deep learning models in the context of mobile UI layout design. Processing layouts differs from processing pixel-level images in that it necessitates processing both the semantic (e.g.\, labels) and spatial (e.g.\, coordinates) content of the layout to model the data properly. To achieve this\, I explore the design problems from both the data and the model side. First\, I present a large-scale UI dataset that accurately specifies the interface’s view hierarchy (i.e.\, UI components and their location). Second\, I contribute the VINS framework\, which is composed of three systems LayVis\, CompVis\, and TransVis that addresses layout-based visual search\, component-based visual search\, and layout generation\, respectively.\nFirst\, I introduce LayVis\, an object-detection layout-based retrieval model. It takes as input a UI image and retrieves visually similar design examples. Next\, I introduce CompVis\, a component-based visual search system to easily retrieve individual UI components via convolutional neural networks (CNNs). Specifically\, for a given query\, the system allows to retrieve (1) text label synonyms\, (2) similar UI components\, and (3) design examples containing such components. Finally\, I present TransVis\, a transformer-based generative framework that investigate how to generate UI layouts according to user specifications and following design practices. It specifically models UI layouts as an ordered sequence of elements based on spatial and semantic relationships for (1) generating complete UI layouts\, (2) auto-completing existing UI layouts seamlessly\, and (3) supporting many design elements per layout.\nOverall\, the work presented in this dissertation contributes to augmenting the UI layout design. Through quantitative and qualitative evaluation of VINS\, we conclude the following: (1) Advanced deep learning models can aid in the development of design assistance methodologies for layout design; and (2) Designers perceive the use of VINS inspiring and useful. Such insights\, combined with the open-sourced large-scale dataset\, can help the research community develop more effective AI-based data-driven design tools. This work presents future opportunities to investigate different deep learning models within the context of layout design and how designers interact with these AI-based models.

SUMMARY:ChE Seminar Series: Catalytic Oxidation of Methane\, the “Other” Greenhouse Gas
DESCRIPTION:ChE Seminar Series Presents: \nDr. Michael Harold \nDepartment of Chemical & Biomolecular Engineering\, University of Houston \nAbstract: \nThe abundant domestic natural gas resources has motivated the accelerated development of natural gas powered vehicles and stationary engines.  With the primary constituent of abundant NG being methane (CH4)\, NG has a higher H:C ratio than gasoline or diesel and therefore its combustion produces less CO2.   However\, CH4 is itself a more potent greenhouse gas (GHG) than CO2 with a GHG potential about 85 times that of CO2. Uncombusted CH4 must be eliminated in order to clear the way for the growth in the NG engine market. Current state-of-the-art Platinum Group Metal (PGM) catalysts are ineffective in eliminating methane. Our research is focused on the study and development of a new class of cost effective structured catalysts with reduced PGM loadings for both stoichiometric and lean methane oxidation. For stoichiometric oxidation we show that the combination of spinel mixed metal oxide (AB2O4) addition and lean-rich feed modulation results in significant enhancement in the catalyst performance. Detailed study of feed modulation parameters (frequency\, amplitude)\, catalyst design (composition\, architecture) and spatiotemporal reactor features provide insight into and optimization of the underlying mechanism. The enhancement is attributed to the transient oxidation of methane conversion inhibitors CO and H2 by the spinel. Up to a 30% reduction in PGM loading is possible with negligible loss in performance. For lean oxidation we study and develop an in situ method to regenerate methane oxidation catalysts. Periodic reductant (H2\, CO) pulsing mitigates the detrimental water poisoning of Pd-Pt catalyst. The pulsing is able to regenerate the catalyst deactivated by water by removal of OH-groups from the catalysts surface\, but also promoted its activity after repeated application of pulsing for several hours. This state of high activity is stable for several hours under the tested lean conditions. \nBio: \nMike Harold is the Cullen Engineering Professor in the Department of Chemical and Biomolecular Engineering at the University of Houston.  With expertise in catalysis and reaction engineering\, Harold is the author of more than 180 peer-reviewed papers and book chapters and has given over 350 presentations and invited lectures.  Harold received his BS at Penn State and PhD from the University of Houston (UH).  He joined the faculty at University of Massachusetts at Amherst in 1985 where he became Associate Professor.  In 1993 Harold joined DuPont Company\, where he held technical and managerial positions.  In 2000 Harold became the Dow Chair Professor and Department Chair at UH\, a position he held for 16 years. Mike was appointed Editor-in-Chief of the AIChE Journal in 2012 and will soon end his 10 year term. His honors include the Excellence in Applied Catalysis from the Southwest Catalysis Society in 2019\, the Ester Farfel Award at UH in 2013\, and AIChE Fellow in 2014. \nPlease contact a.ramsey@northeastern.edu for the seminar link.

SUMMARY:ECE PhD Dissertation Defense: Arjun Singh
DESCRIPTION:PhD Dissertation Defense: Design\, Modeling\, and Operation of Plasmonic Devices for Smart Communication Systems in the Terahertz Band \nArjun Singh \nLocation: 332 ISEC or Teams Link \nAbstract: The terahertz (THz) band is an attractive spectral resource for realizing future communication systems\, with the potential of supporting very high-speed data rates and increasingly dense networks. However\, the lack of a well-developed technology that operates at these frequencies has remained a challenge for the scientific community. The very high propagation losses at THz frequencies and the decimating impact of everyday objects on THz wave propagation necessitate an up-haul of the conventional communication link\, with smart control over the radiation\, propagation\, and detection of THz signals. Additionally\, device physics at THz frequencies\, among them the very high gain requirement and large electrical size\, may render the often-held assumptions of the propagation model invalid. An interdisciplinary approach spanning device design and operation\, and wireless propagation and signal processing is required.\nTo this end\, the proposed research herein addresses the facilitation of an end-to-end communication link with graphene plasmonics as the cornerstone of the fundamental device physics. The devices designed can be utilized to effectively overcome the limited communication distance –The grand challenge of the THz band. Different from other undertakings\, every attempt is made to ac-knowledge and accommodate the complex trade-offs in the design process. First\, a novel graphene based plasmonic array architecture is proposed\, explained\, and modeled. The fundamental radiating element of the array architecture\, called the plasmonic front-end\, consists of a self-sufficient plasmonic source\, a plasmonic modulator that acts as a phase controller\, and a plasmonic nano-antenna for effective radiation. The designed array is compact and provides complete beamsteering support\, with a new tailored algorithm developed for beamforming weight selection. Numerical evaluations and full-wave finite difference frequency domain (FDFD) simulations with COMSOL Multi-physics are utilized to verify array operation. Exploiting these properties\, a multi-beam array design is presented next\, where orthogonal spatial filters are utilized to provide support for spatial multiplexing towards the realization of ultra-massive MIMO (UM-MIMO). Taking this further\, the design considerations of an interleaved plasmonic array are presented\, in which the beamsteering capability is utilized to simultaneously achieve radio frequency interference (RFI) mitigation with channel capacity maximization for multi-user scenarios. Additionally\, to realize the vision of a smart communication system with a programmable wireless environment\, a hybrid reflectarray is presented. The fundamental element is modeled as a jointly designed and integrated metal-graphene patch. Numerical and simulation results are utilized to demonstrate the attractive properties of the reflectarray as compared to other proposed counterparts\, including an independence from the incoming angle of the impinging wave\, dynamic phase control capability\, and strong reflection efficiency. The requirements of a THz communication link and their impact on the common communication protocols are considered next. It is shown that certain scenarios may render regular array operation invalid\, motivating codebook designs that function in the massive near-field Fresnel zone of electrically large THz devices. Numerical simulations and theoretical analysis are presented to highlight their potential in improving system performance and capacity while reducing the system complexity. Finally\, the significant milestones in the fabrication process of these devices are also presented.

SUMMARY:ECE PhD Proposal Review: Michele Pirro
DESCRIPTION:PhD Proposal Review: Scandium-doped Aluminum Nitride for new MEMS technologies \nMichele Pirro \nLocation: 432 ISEC \nZoom Link Meeting ID: 938 0086 0379 https://northeastern.zoom.us/u/abZS2SmtT1 \nAbstract: The increasing demand for data is pushing the MEMS industry to more performant and area-efficient systems to be used in IOT nodes as sensors and RF-components. In this market\, AlN plays a pivotal role thanks to the piezoelectric properties accompanied with good stability over power and temperature in miniaturized devices. In fact\, AlN is already present in different commercial MEM systems\, such as duplexers\, ultrasound generators\, energy harvesters and so on\, proving a mature mass-production process flow. The required more stringent specifications in terms of bandwidth\, losses and efficiency are pushing towards piezoelectric materials with higher coupling coefficient\, but still in a compatible post-CMOS process flow. Luckily\, recent works showed how it is possible to enhance the piezoelectric effect by doping AlN with Scandium\, allowing up to 400% increase in the d33 piezoelectric coefficient. The enhanced acoustic transduction along with the recent demonstration of ferroelectric switching and the post-IC compatibility\, is making Sc-doped AlN a new material with the potential not only to replace AlN\, but also to integrate different functionalities within the same component. Academy and industry all over the world are actively researching the actual potential of the material but there is still a lack of information on high-Sc concentration\, which would allow lower-voltage switching along with higher d33. This work has the main objective to show Sc-concentration > 28% and their piezo/ferroelectric response for a new class of microelectromechanical devices.\nThe proposal will discuss the advance in the process flow of high Sc- concentrations\, showing the impact of the deposition parameters on the material properties. Thin films with good crystallinity on IC-substrate and enhanced d33 are reported\, along with first attempts to resonator-devices. An in-depth ferroelectric characterization will show how coercive field and leakage current are the main limiting factors the material is facing to integrate its memory effect. For this purpose\, the work will present how tuning of Sc-concentration\, substrate-rf and bulk stress can ease these limiting factor\, opening to new acoustic devices with memory functionalities. The last part will focus on the co-integration of acoustic properties with ferroelectric switching for tunable filters and ultrasonic generators in post-IC compatible substrates.

SUMMARY:ECE PhD Proposal Review: Leonardo Bonati
DESCRIPTION:PhD Proposal Review: Softwarized Approaches for the Open RAN of NextG Cellular Networks \nLeonardo Bonati \nLocation: 532 ISEC \nAbstract: The 5th (5G) and 6th generations (6G) of cellular networks\, also known as NextG\, will bring unprecedented flexibility to the wireless cellular ecosystem. Because of its typically closed and rigid market\, the telco industry has incurred high costs and non-trivial obstacles in delivering those new services and functionalities to satisfy the requirements and the demand of NextG networks. To break this trend the industry is now moving towards open architectures based on softwarized approaches\, which will afford network operators flexible control and unprecedented adaptability to heterogeneous conditions\, including traffic and application requirements. Now\, by simply expressing a high-level intent\, operators will be able to instantiate bespoke services on-demand on a generic hardware infrastructure\, and to adapt such services to the current network conditions. Through disaggregation\, network elements will split their functionalities across multiple components—possibly provided by different vendors—interconnected through well-defined open interfaces. The separation of control functions from the hardware fabric\, and the introduction of standardized control interfaces\, will ultimately enable definition and use of softwarized control loops\, which will bring embedded intelligence and real-time analytics to effectively realizing the vision of autonomous and self-optimizing networks.\nThis dissertation work focuses on the design\, prototyping and experimental evaluation of softwarized approaches for the new open Radio Access Network (RAN) of NextG cellular networks. We analyze the architectural enablers\, challenges and requirements for a programmatic zero-touch control of the very many network elements and propose practical solutions for its realization. We prototype solutions by leveraging open-source software implementations of cellular protocol stacks and frameworks\, and heterogeneous virtualization technologies\, including the srsRAN and OpenAirInterface cellular implementations\, and the O-RAN framework. The contributions of this work include (i) the first demonstration of O-RAN data-driven control loops in a large-scale experimental testbed using open-source\, programmable RAN and RAN Intelligent Controller (RIC) components through xApps of our design\, and (ii) CellOS\, a zero-touch cellular operating system that automatically generates and executes distributed control programs for simultaneous optimization of heterogeneous control objectives on multiple network slices starting from a high-level intent expressed by the operators. The effectiveness of our solutions in achieving superior control and performance of the RAN is demonstrated on state-of-the-art experimental facilities\, including software-defined radio-based laboratory setups and open access experimental wireless platforms\, such as Colosseum\, Arena\, and the POWDER-RENEW platform from the U.S. PAWR program.

DESCRIPTION:PhD Proposal Review: Engineering Functional Nanomesh for Advanced Neuroelectronics \nJaehyeon Ryu \nLocation: Zoom Link \nAbstract: Transparent electronics have emerged as promising platforms for neural interfacing by enabling simultaneous electrophysiological recording and optical measurements. Also\, there are high demands for stretchable devices due to their low modulus and compatible interface with irregular and soft neural tissue. However\, current transparent\, stretchable approaches are usually limited by their scalability for neuroelectronic applications. Here\, I present multi-functional nanomesh as an approach to achieve stretchable\, transparent microelectrode arrays (MEAs) with excellent scalability. By stacking mechanical supporting polymer\, gold\, and conductive polymer in a nanomesh structure on elastomer substrate\, multilayer nanomesh-based MEAs show excellent stretchability\, transparency\, and electrochemical properties with single neuron scale dimensions. The performance of these multi-functional nanomesh-based MEAs has been characterized through bench testing\, and I plan to perform in vivo validation in the remaining period of my thesis. These highly stretchable and transparent multilayer nanomesh MEAs are promising for applications ranging from neuroscience to biomedical devices.

SUMMARY:Distinguished Speaker Series in Robotics: Gregory S. Chirikjian
DESCRIPTION:Distinguished Speaker Series in Robotics \nGregory S. Chirikjian: Robot Imagination: Affordance-Based Reasoning about Unknown Objects \nLocation: ISEC Auditorium or Zoom Link \nAbstract: Today’s robots are very brittle in their intelligence. This follows from a legacy of industrial robotics where robots pick and place known parts repetitively. For humanoid robots to function as servants in the home and in hospitals they will need to demonstrate higher intelligence\, and must be able to function in ways that go beyond the stiff prescribed programming of their industrial counterparts. A new approach to service robotics is discussed here. The affordances of common objects such as chairs\, cups\, etc.\, are defined in advance. When a new object is encountered\, it is scanned and a virtual version is put into a simulation wherein the robot “imagines’’ how the object can be used. In this way\, robots can reason about objects that they have not encountered before\, and for which they have no training using. Videos of physical demonstrations will illustrate this paradigm\, which the presenter has developed with his students Hongtao Wu\, Meng Xin\, Sipu Ruan\, and others. \nBio: Gregory S. Chirikjian received undergraduate degrees from Johns Hopkins University in 1988\, and a Ph.D. degree from the California Institute of Technology\, Pasadena\, in 1992. From 1992 until 2021\, he served on the faculty of the Department of Mechanical Engineering at Johns Hopkins University\, attaining the rank of full professor in 2001. Additionally\, from 2004-2007\, he served as department chair. Starting in January 2019\, he moved the National University of Singapore\, where he is serving as Head of the Mechanical Engineering Department\, where he has hired 14 new professors so far. Chirikjian’s research interests include robotics\, applications of group theory in a variety of engineering disciplines\, applied mathematics\, and the mechanics of biological macromolecules. He is a 1993 National Science Foundation Young Investigator\, a 1994 Presidential Faculty Fellow\, and a 1996 recipient of the ASME Pi Tau Sigma Gold Medal. In 2008\, Chirikjian became a fellow of the ASME\, and in 2010\, he became a fellow of the IEEE. From 2014-15\, he served as a program director for the US National Robotics Initiative\, which included responsibilities in the Robust Intelligence cluster in the Information and Intelligent Systems Division of CISE at NSF.

SUMMARY:ECE PhD Dissertation Defense: Jinghan Zhang
DESCRIPTION:PhD Dissertation Defense: Domain Design Space Exploration: Designing a Unified Platform for a Domain of Streaming Applications \nJinghan Zhang \nLocation: ISEC 362 or Zoom Link \nAbstract: Many demanding streaming applications share functional and structural similarities with other applications in their respective domain\, e.g.\, video analytics\, software-defined radio\, and radar. This opens the opportunity for specialization to achieve the needed efficiency and/or performance.\nPlatforms integrating many accelerators (ACCs) is a primary approach for efficient\, high-performance stream computing.\nHowever\, designing one platform for each application is not economical due to the high costs of nonrecurring engineering (NRE) and time-to-market (TTM).\nTo this end\, the concept of domain platforms is proposed\, which takes advantage of similarities across applications and designs one unified platform to accelerate a domain of applications instead of focusing on a single reference application.\nThis dissertation approaches designing domain platforms from a function-level (kernel-level) acceleration through a heterogeneous ACC-rich platform\, where each ACC is specialized to accelerate a particular function.\nThere is a great challenge to select ACCs allocated in the domain platform\, considering the large design space and performance balance across many applications.\nHowever\, current Design Space Exploration (DSE) tools only focus on an individual application in isolation (e.g.\, one particular vision flow) for allocating a platform\, but not a set of similar applications.\nThis dissertation introduces Greedy Guided Mutation (GGM) to speed up the mutation in the GIDE algorithm\, which calculates an ACC score according to current allocation to guide mutation.\nAlternatively\, Rapid Domain Platform Performance Prediction (RDP^3) methods are introduced to replace a large number of the slow platform assessment in domain DSE\, which avoids the complex application binding exploration.\nIn the experiments\, GGM reduces 84.8% of exploration time with a 0.23% loss of the final OpenVX domain platform’s performance.\nRDP^3 using a machine learning method yields an even more significant speedup\, saving 90.8% of exploration time with only 0.0003% performance loss.\nDmDSE is a milestone to broaden DSE scope from individual applications to the domain level. It tremendously pushes the domain platform design from manually and engineering experience guided into a general automatic process.

SUMMARY:ECE PhD Proposal Review: Anahita Moradmand
DESCRIPTION:PhD Proposal Review: Robust Observer Structures and Control Design for Linear and Nonlinear Dynamical Systems with Applications \nAnahita Moradmand \nLocation: Zoom Link \nAbstract: This thesis focuses on special class of observers and controllers for different and seperable nonlinear systems. In the first step\, a robust fault detection approach using observers for linear systems is proposed where we combine the unknown inout observer UIO and an extended proportional integral observer PIO\, which has a fading term for robust fault detection. The integrated observer is called proportional integral fading unknown input observer (PIFUIO).\nFurthermore\, we extend our result to nonlinear systems with special structures as the design of nonlinear observer had limitation for general types of nonlinear systems. In the second step\, analysis and design of positive systems is considered whereby positive stabilization and the design of positive unknown input observer (PUIO) are introduced. Also\, the robust stability analysis of this class of systems is studied in which the robust stability is formulated in terms of LMI. the class of separable positive nonlinear systems is also analyzed and the design of observer and controller are provided. Finally\, we extend our desgin from Lipschitz type nonlinearity to state-dependent type by focusing on interconnected systems where we propose a distributed control architecture to take advantage of the global performance similar to centralized control and leverage the benefits of decentralized control.
