Talk Title: Pricing Randomness, Risk and Flexibility: Market Design For a Smarter Grid
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: The current moment finds the world's energy infrastructure at the threshold of rapid transformation. Today's power systems are defined by increasing penetration of renewable and distributed energy resources on the supply side, and the emergence of flexible loads on the demand side. Clearly, market institutions have a crucial role to play in this transformation as well. Through market analysis, design and optimization, this talk will explore how such institutions can evolve to address four key characteristics of modern power systems: uncertainty, risk, flexibility and strategic behavior.
First, given that user flexibility is considered one of the most valuable, yet still untapped resources available for accommodating the transition to renewables, an explicit market for flexibility is designed and analyzed. Users report preferences for service over a finite time horizon to a scheduler which shapes the aggregate demand profile to the output of a renewable generator, while minimizing the costs associated with resorting to thermal generation. Social welfare properties of competitive equilibria and an accompanying mechanism are studied. As the competitive equilibria arise from a convex relaxation of the binary constrained load scheduling problem, an interpretation of equilibrium schedules as giving a stochastic method for generating an optimal schedule in the large economy limit is also examined. Next, focusing on the transmission component of the power grid, rather than arrange advance supply and account for real time imbalances in supply and demand separately, a two-stage, stochastic market clearing paradigm is considered. Probabilistic information regarding renewable generation is used to couple day ahead and expected real time recourse decisions, increasing efficiency. A two-stage mechanism is developed for a two-sided exchange with primary and ancillary generation and demand response, implementing a sequential competitive equilibrium (SCEq). Allowing for strategic behavior, sufficient conditions are provided for the existence of efficient sequential Nash equilibria.

Speaker: Sutanu Sarkar, University of California at San Diego
Talk Title: Wakes in the Natural Environment
Abstract: Environmental wakes are produced by flows past structures which are engineered (e.g., oceanic submersibles, aerial vehicles, wind turbines, urban structures) or in nature (hills, mountain ranges, islands, seamounts). These wakes impact drag on the incident flow as well as transport of material, pollutants and environmental constituents. We will illustrate wake flow physics with a few examples studied using high-resolution simulation. The wake of a blunt object such as a disk will be contrasted with a streamlined object such as a prolate spheroid with respect to mean velocity, turbulence levels, flow instabilities and coherent structures. We will discuss both a constant density fluid and a density-stratified fluid where buoyancy inevitably alters the wake of the body. We will also present an example from nature, an oceanic current past a submerged hill, where we find synchronization of wake vortices with subharmonics of the oscillating tide and also states of high drag.

Talk Title: Multi-functional Additive Manufacturing of Smart Materials and Devices
Series: Epstein Institute Seminar
Abstract: By combining various materials that serve mechanical, electrical, chemical, thermal, and/or optical functions into a component with locally controlled distributions, we can produce composites and multi-material objects with a higher degree of functionality than would normally be found in a pure material part. In addition to material combination, by integrating hierarchial surface structures with dimensions spanning from nanoscale to macroscale, superior functions can be engineered and integrated into the component. However, to manufacture such multi-material multi-scale components directly out of a digital model without assembly, grand challenges still exist in material distribution and localized material phase control. In this talk, I will present our recent research in addressing these manufacturing challenges by integrating external fields in varied additive manufacturing processes. First, I will introduce external field assisted projection stereolithography technologies for productions of functional particle-polymer objects with hierarchical surface structures. After that, I will present a electrowetting-assisted direct ink writing technology for productions of conductive patterns on rough substrates at meters per second speeds for energy related applications. More energy related applications will be presented with a self-binding selective laser sintering method. In these additive manufacturing processes, I will discuss the effectiveness of integrations of external fields on controlling local material distributions and combining multiple materials. Applications of the 3D printed multi-functional materials and components in soft robotics, electronics packaging, and energy storage will be demonstrated.

Conferences, Lectures, & Seminars
Speaker: Tirtha Banerjee, UC Irvine
Talk Title: TBD
Abstract: The traditional motivation behind studying the dynamics of turbulent wind flow in vegetation canopies has been to understand the nature of mass, momentum and energy exchange between the land surface and the atmosphere. The nature of this interaction determines the microclimate in a forest environment where plants exchange carbon and water and its understanding is relevant for a plethora of applications ranging from ecology, hydrology, agriculture and the modeling of weather and climate. However, the fundamental nature of turbulence in a vegetation canopy is significantly different from the atmospheric surface layer lying above, which means that scaling laws and exchange coefficients from traditional wall bounded flows are not applicable. In a forest canopy, momentum absorption happens not only at the ground surface but throughout the depth of the canopy, resulting in a unique roughness sub layer. Instead of a log-layer, the mean velocity profile is inflected, second order moments are variable with height and skewnesses are large. Large scale coherent structures impart significant impact on the turbulence dynamics. Sweeping motions arising out of downdraft motions of counter-rotating vortices dominate eddy fluxes. A mixing layer model is found to be a better model for describing canopy flows. High frequency measurements and computational fluid dynamics modeling, especially Large Eddy Simulations (LES) has been instrumental in revealing the nature of canopy turbulence in the last few decades. Now this knowledge is being used to push the frontiers of our limited understanding of how wildland fires behave. The main controls on wildland fire behavior -“ fuel (canopy and grasslands), weather and topography are strongly influenced by fine scale physics of canopy turbulence. We will demonstrate that further developments in the understanding of canopy turbulence can benefit wildfire modeling tools and developing actionable management strategies.

Speaker: Dr. Stephen J. Wright, University of Wisconsin-Madison
Talk Title: The Role of Complexity Bounds in Optimization
Abstract: Complexity analysis in optimization seeks upper bounds on the amount of work required to find approximate solutions of problems in a given class with a given algorithm, and also lower bounds, usually in the form of a worst-case example from a given problem class as regards the work required by a particular class of algorithms. The relationship between theoretical complexity bounds and practical performance of algorithms on "typical" problems varies widely across problem and algorithm classes, and relative interest among researchers between these two aspects of algorithm design and analysis has waxed and waned over the years. This talk surveys complexity analysis and its relationship to practice in optimization, with an emphasis on linear programming and convex and nonconvex nonlinear optimization, providing historical (and cultural) perspectives on research in these areas.

Speaker: Tim Colonius, Caltech
Talk Title: Simulation of bubbly, cavitating flows with application to shock- and ultrasound-based medical therapies.
Abstract: Models and numerical methods for simulating bubbly, cavitating flows have benefitted from recent advances in sharp and diffuse interface-capturing schemes, but many challenges remain to be solved before they can be routinely used to predict the complex, multiscale flows associated with important applications in engineering and medicine. In particular, the complex phase boundary, small length scales, and fast time scales associated with the dynamics of bubbles and clouds of bubbles strain existing algorithms and computational resources. In this talk, I will review different formulations for multiphase/multicomponent flows that involve large changes in volume, including methods that explicitly resolve the material interface, and ones that model the mixture as either homogeneous, or as a dilute dispersion of spherical bubbles. These methods are demonstrated in applications involving the high-intensity ultrasound and shock waves used for medical imaging and intra- and extra-corporeal manipulation of cells, tissue, and urinary calculi. Such waves are currently used to treat kidney stone disease, plantar fasciitis, and bone nonunion, and they are being investigated as a technique to ablate cancer tumors and mediate drug delivery. In many applications, acoustic waves induce the expansion and collapse of preexisting or newly cavitating bubbles. The resulting bubble dynamics generate large, localized stresses and strains that can be beneficial or deleterious depending on how effectively they can be controlled. I will describe efforts aimed at simulating the collapse of bubbles, both individually and in clusters, in order to characterize these mechanical stresses and strains.

Talk Title: The Fate and Transformation of Nitromethanes during Wastewater Reuse Processes
Abstract: As water resources become increasingly scarce, potable reuse of wastewater is considered to be a potential solution. There are increasingly number of treatment processes currently in used in full- and pilot- scale water reclamation plants involves ozonation. Ozone is considered to be a highly effective oxidant and disinfectant. However, previous research has demonstrated that ozonation of wastewater overall drastically increases chloropicrin formation potential during subsequent chlorination. Nitromethane has been be proven to be the immediate precursor of chloropicrin prior to chlorination, however nitromethane itself is unlikely to be present in wastewater naturally. Previous research indicates that ozone directly oxidizing secondary amines bearing an N-methylamine functional group lead to nitromethane formation.
Ozonation is widely used in wastewater reclamation treatment trains, either for micropollutant control or as a disinfectant and pre-oxidant in certain reuse processes. Nitromethane formation will be strongly promoted post ozonation but its fate through other treatment process remains uncharacterized, which raise the question of can nitromethane be detected in final product water. The objects of this study are to demonstrate that nitromethane formation post ozonation in real full- and pilot scale reuse plants and to characterize the nitromethane fate throughout the entire treatment trains.
In this work, the fate of nitromethane through water reuse treatment trains was characterized by analyzing samples from five reuse operations employing ozone. Nitromethane was poorly (90%) nitromethane. Bench-scale experiments were conducted to verify low removal by RO in clean systems and with wastewater effluent, and to quantify the kinetics of direct and indirect photolysis of nitromethane in UV/AOP.
These results indicate that nitromethane presents a unique hazard to direct potable reuse systems, due to its ubiquitous formation during wastewater ozonation, poor removal by RO and UV/AOP, and facile conversion into genotoxic halonitromethanes upon chlorine addition.

Speaker: Dr. David Simchi-Levi, MIT
Talk Title: Statistical Learning in Operations Management
Abstract: Traditionally, statistical learning is focused on either (i) online learning where data is generated online according to some unknown model; or (ii) offline learning where the entire data is available at the beginning of the process. In this talk we show that combining both approaches can accelerate learning. Specifically, we show that difficult online learning problems can be reduced to well-understood offline regression problems. We demonstrate the impact of our work in the context of product recommendation, multiclass classification problems, personalized medicine and dynamic pricing.

Speaker: Malancha Gupta, USC
Talk Title: Initiated Chemical Vapor Deposition of Polymer Coatings and Membranes
Abstract: Initiated chemical vapor deposition (iCVD) is a solventless process that can be used to synthesize polymer films and coatings with a range of functionalities including hydrophilicity, hydrophobicity, light-responsiveness, and thermo-responsiveness. This talk will present the mechanism, capabilities, and advantages of the iCVD process. We will demonstrate that the iCVD process can be used to modify the surface properties of fibers, membranes, and microfluidic channels for applications in textiles, separations, and diagnostics. We will also demonstrate that polymers can be deposited onto low vapor pressure liquids including ionic liquids and silicone oils to fabricate ultrathin freestanding polymer films, nanoparticles, core-shell particles, and gels. We will also show that lowering the temperature of the substrate below the freezing point of the monomer leads to the formation of polymer membranes. These membranes can be deposited onto porous substrates to create hierarchical porous-on-porous structures that can enable improved filtration for water purification and sensor applications.
