ESE Ph.D. Thesis Defense: “Graph Machine Learning under Requirements”

Greenberg Lounge (Room 114), Skirkanich Hall 210 South 33rd Street, Philadelphia, PA, United States

Graphs are powerful mathematical tools that enable modeling of complex systems. Graph machine learning exploits possibly unknown data structures, which provides a unified approach to tackle a wide variety of problems. However useful in practice, graph machine learning solutions tend to suffer from three main limitations: they do not scale with the size of the […]

ESE Seminar: “Designing emerging computing systems with ferroelectric devices”

Greenberg Lounge (Room 114), Skirkanich Hall 210 South 33rd Street, Philadelphia, PA, United States

This talk will present a brief overview of advances in ferroelectric devices and their integration into computing systems to provide novel functionality and energy efficiency in various data intensive applications. The talk will emphasize on cross-stack design opportunities in designing stacked intelligent 3D memory systems.

MEAM Seminar: “Examples of Elasto-Capillary Mediated Interactions on Thin Elastic Film”

Levine 307 3330 Walnut Street, Philadelphia, PA, United States

I plan to tell two short stories. The first story is about a new drop fluidics that uses a deformable and stretchable elastomeric film as the platform. Such a soft film decorated with magnetic particles can be deformed locally with an external magnetic field. When these deformations are coupled with capillary force, small liquid drops […]

MEAM Seminar: “Tribosintering of Metal Oxide Nanocrystal Antiwear Additives: Growth, Wear, and Modeling”

Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Machinery relies on lubrication to regulate the friction and wear at contacting interfaces. As new lubricants become less viscous to comply with environmental and cost-saving standards, the risk of surface-initiated machine failure grows. We show that metal oxide additives in low-viscosity lubricants will form protective coatings, or tribofilms, in situ at contacting interfaces. Compared to […]

BE/PICS Joint Seminar: Uma Balakrishnan and Kunal Poorey, Sandia National Laboratories

Room 534 A Wing, 3401 Walnut 3401 Walnut Street, Philadelphia, PA, United States

These talks will be held jointly, with each talk 30 minutes each (1 hour total). Talk 1: "Optimizing Anomaly Detection for GenAI based Digital Twins of Wearable Data" (Uma Balakrishnan) In this presentation, we introduce a methodology that utilizes both real and synthetic datasets (digital twins) to address the uncertainties associated with anomaly detection thresholds […]

CBE Doctoral Dissertation Defense: “Fabrication of Functional Nanostructured Polymers Based on Thermotropic and Lyotropic Liquid Crystals Derived from Sustainable Resources” (Ruiqi Dong)

Towne 337

Abstract: Nanostructured materials with interconnected nanoscale structures have garnered significant attention due to the ability to precisely regulate molecular transport by tuning molecular-level properties and offering more functional interfaces for interactions compared to bulk systems. Through self-assembly, liquid crystal (LC) mesophases offer a route to achieve nanostructured polymers, a promising alternative to traditional nanostructured inorganic […]

CBE Doctoral Dissertation Defense: “MEMS-Based Electrochemical Power Sources for Extended Operational Duration of Micro Unmanned Vehicles” (Yanghang Huang)

Room 221, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

Abstract: Micro unmanned vehicles, defined as 25-gram to 5-kg in weight, are increasingly being utilized in applications such as search and rescue or agricultural monitoring. Such vehicles are typically powered with lithium-ion batteries. However, vehicle operational efficiency and capability are often compromised by the limited energy density of these batteries, resulting in short operational duration. […]
