SUMMARY:MEAM Seminar: "Effect of Nanoparticle Size on the Mechanical Properties of Nanoparticle (NP) Assemblies"
DESCRIPTION:Nanoparticle assemblies (NPAs) have attracted tremendous interests of various research communities. The particle-size-effect on mechanical properties of NPAs is systematically studied. With decreasing the particle size d from 300 nm to 10 nm\, the SiO2 NPAs become drastically harder (∼39×)\, stiffer (∼15×)\, and tougher (>3.5×). The results are consistent with the data scattered in the literature for various nanoparticle (NP) systems\, indicating a fundamentally universal d-effect for all NPAs. A model is developed to correlate the hardness and the NP junction (NPJ) strength f. Here\, f is mainly due to van der Waals and capillary interactions\, roughly a constant (140 nN) for d = 100–300 nm\, and then f decreases with decreasing d from ∼100 nm. The deformation mechanism of NPAs (for indentation depth ≫d) is shear plasticity involving shear breaking of NPJs. The fundamental mechanism for the d-effect is that\, with decreasing d\, the NPJ’s planar density increases much faster than the decrease of f. Moreover\, three deformation mechanisms of NPAs\, (1) nanoparticle dislodging\, (2) shear-band formation\, and (3) cracking are naturally d-dependent. These new findings can provide important insights into the fundamental understanding of the inter-NP interaction\, the mechanical behavior of the NPAs\, and the design of robust NP-based devices. If time allows\, as an independent topic\, the experimental characterization of freestanding membrane will also be briefly discussed.

SUMMARY:MEAM Seminar: “Thermalization of Bulk Magnetic Materials in Spin-Lattice Dynamics Simulations”
DESCRIPTION:Spin-lattice dynamics (SLD)\, an increasingly popular simulation method which simultaneously computes both atomic displacements and spins\, offer new possibilities for modeling the temporal evolution of systems where the coupling between these atomic features are relevant such as spin caloritronics\, heat assisted magnetic recording\, magnetocaloric responses and magnetic nanoparticle hyperthermia. To accurately model and understand these magnetic materials\, SLD must capture spin-spin and spin-lattice interactions in a physically meaningful way. Recent work indicates that including a local magnetic anisotropy term in SLD simulations may be necessary to appropriately couple the magnetic spins to the atomic system to allow for thermal transport between the systems. A key obstacle to the adoption of this term is the lack of knowledge of its parameters for a broad range of materials. Ab initio calculations can obtain these parameters\, but these calculations are limited by energy scales\, system size and computational cost. A new framework using bulk experimental properties is introduced to obtain these parameters which avoids some or all of these challenges of the ab initio method. Results from this framework are discussed for iron along with the validation procedure for the found parameters.

SUMMARY:MEAM Seminar: "Machine Learning for Robotics: Achieving Safety\, Performance and Reliability by Combining Models and Data in a Closed-Loop System Architecture"
DESCRIPTION:The ultimate promise of robotics is to design devices that can physically interact with the world. To date\, robots have been primarily deployed in highly structured and predictable environments. However\, we envision the next generation of robots (ranging from self-driving and -flying vehicles to robot assistants) to operate in unpredictable and generally unknown environments alongside humans. This challenges current robot algorithms\, which have been largely based on a-priori knowledge about the system and its environment. While research has shown that robots are able to learn new skills from experience and adapt to unknown situations\, these results have been limited to learning single tasks\, and demonstrated in simulation or lab settings. The next challenge is to enable robot learning in real-world application scenarios. This will require versatile\, data-efficient and online learning algorithms that guarantee safety when placed in a closed-loop system architecture. It will also require to answer the fundamental question of how to design learning architectures for dynamic and interactive agents. This talk will highlight our recent progress in combining learning methods with formal results from control theory. By combining models with data\, our algorithms achieve adaptation to changing conditions during long-term operation\, data-efficient multi-robot\, multi-task transfer learning\, and safe reinforcement learning. We demonstrate our algorithms in vision-based off-road driving and drone flight experiments\, as well as on mobile manipulators.

SUMMARY:MEAM Seminar: "Hierarchical Task-Parameterized Learning from Demonstration "
DESCRIPTION:Many modern humanoid robots are designed to operate in human environments\, like homes and hospitals. Such robots could help humans accomplish tasks and lower their physical and/or mental workload. However\, robot users in homes and hospitals typically are not familiar with robotics or programming\, therefore it is difficult for them to adapt robots to their specific needs and environments. To remedy this situation\, many researchers turn to learning from demonstration (LfD)\, which enables a robot to emulate natural human movement as opposed to having an operator devise control policies and reprogram the robot for every new situation it encounters. \nWe suggest a hierarchical LfD structure of task-parameterized models\, particularly for object movement tasks that are ubiquitous in everyday life and could benefit from robotic support. Inspired by the task-parameterized Gaussian mixture model (TP-GMM) algorithm\, we develop the hierarchical structure and explicitly utilize task parameters to maximize the expected performance in a new situation from a few demonstrated situations. The robot can thus determine when it should request new demonstrations when the expected performance is too low. Other advantages of our approach include that a wider range of task situations can be modeled in the same framework without deteriorating performance and that adding or removing demonstrations incurs low computational load\, and thus the robot’s skill library can be built incrementally. We show these advantages in a simulated task and in the real world where naïve participants collaborated with a Willow Garage PR2 robot to move a handheld object. For most tested scenarios our hierarchical method achieved significantly better task performance and subjective ratings than both a passive model with only gravity compensation and a single TP-GMM encoding all demonstrations.

SUMMARY:ESE Seminar: "Caching and Coding in Networks: Rate Efficiency\, Age Efficiency"
DESCRIPTION:Caching is of primary importance in the Internet-of-Things (IoT) and in particular in information-centric network (ICN) architectures where the focal point is content rather than where it can be retrieved from. As a result\, in ICN networks one can replicate and store (or cache) content at various nodes throughout the network so that it can be accessed faster locally without burdening the server and the global network. Traditionally\, caching has been studied on the network layer and its role is to bring content close to the end users. However\, it is now known that the role of caching is beyond storing portions of data. \nIn this talk\, we undertake a holistic approach to cache-aided broadcast networks and show how smart cache design facilitates coding opportunities on the physical layer\, leading to scalable gains in rate and latency. We next address several practical aspects of caching networks by introducing the framework of “caching on the fly” where nodes can cache overheard packets. Identifying simple but efficient coding actions\, we devise policies that schedule coding actions (as opposed to traditional schemes that schedule different users). Within this framework\, we design schemes that are practical\, low complexity\, robust to dynamics of network statistics\, and efficient not only in traditional measures of rate and latency\, but also in new performance measures such as age of information.

SUMMARY:MEAM Ph.D. Thesis Defense: "Coarse-graining of Atomistic Models to the Continuum Scale with Applications to Elastodynamics and Diffusive Processes"
DESCRIPTION:Nonequilibrium phenomena are ubiquitous in nature as well as industrial applications. However\, their modeling and simulation faces a strong compromise between physical fidelity and computational efficiency\, with atomistic simulations and continuum descriptions lying towards the two ends of this spectrum. \nIn this dissertation we will first revisit several continuum modeling strategies for the formulation of nonequilibrium evolution equations\, and show by means of an example\, inconsistencies that can arise between the various formalisms. This example will serve as a motivation for developing coarse-graining strategies that can directly link atomistic and continuum models in the context of reversible and irreversible evolutions. With regard to reversible phenomena\, we will present an upscaling scheme that provides a new angle to the classical thermodynamic description of the elastodynamics of solids at finite temperature as the spatio-temporal continuum limit of atomistic Hamiltonian dynamics. This scheme identifies suitable macroscopic (slow) variables and provides its effective equations of motion via elimination of the fast degrees of freedom in the limit of infinite time/space scale separation. In addition\, it provides highly intuitive mathematical explanations to various well-known thermodynamic relations. For purely irreversible processes\, a novel coarse-graining strategy is proposed that numerically delivers the entire continuum evolution equation (and not just parameters therein) from particle fluctuations via an infinite-dimensional fluctuation-dissipation relation. The methodology is exemplified for a diffusion process with known analytical solution\, where an excellent agreement is obtained for the density evolution. Finally\, as an outlook\, data-driven techniques are explored to gain understanding in irreversible structural transformations in colloidal crystallites.

SUMMARY:MEAM Seminar: "Tribofilms at the Asperity Scale"
DESCRIPTION:The presentation will start with an introduction to tribology. This term was first used in a 1965 UK government report which identified the economic loss due to preventable wear and poor friction performance. It helped bring together the diverse community of engineers and scientists that need to collaborate in order to tackle the complex interactions that are central to friction and wear processes. The introduction will conclude with a brief overview of lubricant technology and the associated scope of research themes that support development of new lubricants. \nThe core topic will cover recent advances in our understanding of the formation of the lubricant generated boundary or tribofilms that help control friction and wear processes. Our approach has been to develop new methods and tools that allow us to study the interaction of materials\, surface morphology\, stress and chemical reactivity at the asperity scale within macro scale lubricated rough surface sliding contacts. Highly detailed surface topography\, surface elemental analysis and rough surface contact simulation results\, obtained from carefully controlled wear experiments\, have been mapped onto common asperity scale grids. The results clearly establish that tribofilms initiate very quickly at localized high stress contact spots within the overall macro scale contact footprint. Complementary work in high stress but well separated sliding contacts shows that direct surface contact is not necessarily required to generate surface films. Both sets of experimental results are consistent with stress augmented surface reaction mechanisms that are now being studied by multiple researchers in this field. These developments have shed considerable light on mechanisms that have been elusive for more than 50 years which are key to the performance of lubricants. \nFinally some thoughts on future challenges in tribology and lubrication will be offered. A recent study sponsored by the Society of Tribologists and Lubrication Engineers (STLE) has identified key science and technology\, industry\, regulatory and global trends that will impact lubrication and tribology. These include increasing electrification of personal vehicles\, new and emerging energy sources and the role that tribology plays in enabling new technology development.

SUMMARY:ESE & GRASP Seminar: "Efficient Computing for AI and Robotics"
DESCRIPTION:Computing near the sensor is preferred over the cloud due to privacy and/or latency concerns for a wide range of applications including robotics/drones\, self-driving cars\, smart Internet of Things\, and portable/wearable electronics. However\, at the sensor there are often stringent constraints on energy consumption and cost in addition to the throughput and accuracy requirements of the application. In this talk\, we will describe how joint algorithm and hardware design can be used to reduce energy consumption while delivering real-time and robust performance for applications including deep learning\, computer vision\, autonomous navigation/exploration and video/image processing. We will show how energy-efficient techniques that exploit correlation and sparsity to reduce compute\, data movement and storage costs can be applied to various tasks including image classification\, depth estimation\, super-resolution\, localization and mapping.

SUMMARY:MEAM Seminar: "Fault-Tolerant Control on VTOL Aircraft"
DESCRIPTION:High-speed rotorcraft such as coaxial compound helicopters have a significant degree of control redundancy that can be exploited to minimize power requirement\, noise\, and vibration\, in various flight conditions. This lecture focuses on a new idea – how control redundancy can be leveraged to compensate for control actuation failure. Both adaptive as well as robust strategies are examined\, and operation post-failure is demonstrated via simulation. Multi-copters with greater than four rotors (hexacopters\, octocopters\, etc.)\, also offer control redundancy\, allowing for safe operation post-failure by using the remaining (uncompromised) rotors. The lecture will examine the kind of failures that can be compensated on classical hexacopters and octocopters\, along with the changes in rotor operational speed requirements\, and the associated physics\, post-failure.

SUMMARY:PICS Seminar: "Impact of Non-Native Structures in Ionic Liquid-Ionic Liquid Mixtures on Phase Equilibria Properties of Gases"
DESCRIPTION:Ionic liquids are substances that are composed entirely of ions. Negligible vapor pressures and the availability of a large number of cations and anions to tune physicochemical and biological properties for a given chemical process have been the primary drivers for research in this field over the last two decades. Majority of these investigations have focused primarily on elucidating changes in the properties of pure ionic liquids by altering the cation\, anion or substituents on the ions. Another approach to expand the range of available ionic liquids is to form ionic liquid-ionic liquid mixtures. From a thermodynamic point of view\, the knowledge of the extent of non-ideality in these binary ionic liquid mixtures and the molecular level details enable a priori prediction of thermophysical properties of ionic liquid mixture. In this presentation\, we will demonstrate that the difference in the molar volume of the ionic liquids forming the mixture and the difference in the hydrogen bonding ability of the anions can serve as metrics for the prediction of non-ideality in the binary ionic liquid systems. Such non-idealities are quantified in terms of the local structural organization of anions around the cation. We will further highlight that these non-native structures lead to a different dissolution mechanism for CO2 in mixtures in comparison to that for pure ionic liquids although the CO2 solubilities obey apparent ideal mixing rule. On the other hand\, an examination of NH3 solubility in binary ionic liquid mixtures reveals a non-ideal NH3-solubility behavior.

SUMMARY:ESE Seminar: "Connecting Bits to the Physical World"
DESCRIPTION:Analog\, RF and power integrated circuits are the key connectors between the physical world and the digital or cyber world. In this talk I will give my perspective on broader research trends in analog integrated circuit design research and illustrate several of these trends with results from my research group. The analog circuit design discipline emerged in conjunction with electronics and as such has many decades of history. At the same time\, electronics are constantly undergoing tremendous changes. In recent decades the key platform for integrated circuits has been CMOS. Under the impetus of Moore’s Law\, CMOS transistors have scaled by orders of magnitude\, which drove the necessity of a constant rejuvenation of analog design techniques. Innovations in analog design are an intricate interplay between novel devices\, novel circuit paradigms and novel signal processing. Recently we have been experiencing a shift from traditional analog-to-digital conversion\, to analog-to-information conversion (based on compressive sampling)\, and now to analog-to-feature conversion. This is an example of a top-down shift driven by changing application needs\, in particular emerging machine-learning systems. Scaling transistors does not only allow for higher system integration\, but also enables significant power reductions. Combining advanced transistors with novel circuit design paradigms encoding analog information in the time domain makes it now possible to design integrated circuits that require less than 1nanoW to operate. These innovations\, in turn\, create bottom-up opportunities for entirely new classes of systems\, e.g.\, for the Internet of Things.

SUMMARY:MEAM Seminar: "Data-driven Discovery of Governing Physical Laws in Engineering\, Physics\, and Biology"
DESCRIPTION:A major challenge in the study of dynamical systems is that of model discovery: turning data into models that are not just predictive\, but provide insight into the nature of the underlying dynamical system that generated the data. This problem is made more difficult by the fact that many systems of interest exhibit parametric dependencies and diverse behaviors across multiple time scales. We introduce a number of data-driven strategies for discovering nonlinear multiscale dynamical systems and their embeddings from data. We consider two canonical cases: (i) systems for which we have full measurements of the governing variables\, and (ii) systems for which we have incomplete measurements. For systems with full state measurements\, we show that the recent sparse identification of nonlinear dynamical systems (SINDy) method can discover governing equations with relatively little data and introduce a sampling method that allows SINDy to scale efficiently to problems with multiple time scales and parametric dependencies. Specifically\, we can discover distinct governing equations at slow and fast scales. For systems with incomplete observations\, we show that the Hankel alternative view of Koopman (HAVOK) method\, based on time-delay embedding coordinates\, can be used to obtain a linear model and Koopman invariant measurement system that nearly perfectly captures the dynamics of nonlinear quasiperiodic systems. We introduce two strategies for using HAVOK on systems with multiple time scales. Together\, our approaches provide a suite of mathematical strategies for reducing the data required to discover and model nonlinear multiscale systems.

SUMMARY:PICS Seminar: "Topology\, Geometry\, and Fracture in Networked Materials: A Tale of Scales"
DESCRIPTION:The skeleton of many natural and artificial structures may be abstracted as networks of nonlinearly interacting elements. Examples include rubber\, gels\, soft tissues\, and lattice materials. Understanding the multiscale nature of deformation and failure of networked structures hold key for uncovering origins of fragility in many complex systems including biological tissues and enables designing novel materials. \nI will start by an overview of our prior work on modeling polymer chains with sacrificial bonds and hidden length; a topological feature that was previously hypothesized to be responsible for increased toughness and fracture resistance in animal bone. Our model combines nonlinear entropic elasticity with transition state theory for bond breakage and formation to predict rate dependence and time dependent healing in these systems in the quasi-1D limit. I will then introduce an extension of this model  to a discrete 2D setting (at the scale of 10s of microns) that enables exploring interplay of topological and geometrical features such as coordination number\, cross linking density\, and disorder with mechanical deformation and fracture. Specifically\, we identify a non-monotonic rate dependence of the reaction force and dissipated energy as well as a transition in mode of failure from diffusive to localized with increased pulling rate. Furthermore\, we show that networks with small-world architectures\, balancing clustering and average path length\, may lead to an optimum fracture toughness. \nTo generalize our results to larger scales relevant for engineering and material science applications\, I will discuss our recent efforts in adopting an extended version of the Quasi-Continuum (QC) method to studying polymer networks across scales. In regions of high interest\, for example near defects or cracks\, each polymer chain is idealized using the worm like chain model. Away from these imperfections\, the network structure is computationally homogenized\, using Hill-Mandell’s principle\, to yield an anisotropic material tensor consistent with the underlying network structure. Dynamic adaptivity provides a seamless transition across the two models. Overall\, the proposed method provides a multi-resolution capability by retaining explicit representation of small scale heterogeneities and topological features\, where they matter near the crack tips\, while still accurately accounting for bulk elasticity and loading. We show several examples verifying our approach and illustrate the potential of the method for testing the influence of small scale features in controlling the macroscopic response.  We discuss the implications of our findings for the analysis and design of tough networks.

SUMMARY:MEAM/MSE Special Seminar: "Scalable Functional Phase Change Materials for Displays and Photonic Non-von Neumann Computing"
DESCRIPTION:In electronics\, doping silicon results in one of the most versatile functional materials ever employed. The pursuit of such functional materials in the optical domain is an area of great interest in the photonics community. I hope to convince you that whatever route photonics takes\, a class of materials known as phase change materials\, will play a key role in its commercialization. These materials can be addressed electrically\, and whilst this can be used to control optical signals on photonic circuits this can also be used to create displays and smart windows. In this talk\, I hope to give an overview of these applications of these materials with a view towards their near-term applications in displays\, and their longer-term potential in integrated photonic memories to photonic machine-learning hardware components\, with a few of our recent results in this area.
