MEAM Doctoral Dissertation Defense: “Problems in Nonlinear Homogenization: Bounds, Estimates, Macroscopic Instabilities, and Post-Bifurcation Response”

Towne 309 220 S. 33rd Street, Philadelphia, PA, United States

This talk is concerned with the use of nonlinear homogenization to study the effective response of composites. We look to illustrate the effect that constitutive assumptions have on the methods by which such estimates can be obtained, as well as on the actual effective, or homogenized, response of the material. Although helpful in ensuring existence […]

CBE Seminar: “Examining Heterogeneous Populations of Microbes at the Single Cell Level Using Stabilized Emulsions”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Abstract: Conventional methods in microbiology can be limited by long assay execution and analysis times, large reagent volumes, and high single-use supply costs. These limitations can be overcome using drop-based microfluidics in which picoliter-sized, water-in-oil emulsions serve as independent microreactors, allowing for the compartmentalization of microbes and high-throughput assaying at the single cell level. Here, […]

MSE Seminar: “Science and Applications of Topological Photonics across the Electromagnetic Spectrum”

Auditorium, LRSM Building 3231 Walnut Street, Philadelphia, PA, United States

The 2016 Nobel Prize in Physics was awarded to Kosterlitz, Thouless, and Haldane for their pioneering theoretical work on the novel and counter-intuitive phases of matter that are now referred to as topological phases. Almost half a century after these researchers applied powerful mathematical techniques of topology to condensed matter systems, a new rapidly developing […]

ESE Seminar: “Information Security for the Connected World”

PICS Conference Room 534 - A Wing , 5th Floor 3401 Walnut Street, Philadelphia, PA, United States

Abstract: An all-wireless vision connecting billions of devices is finally in sight with the Internet-of-Everything paradigm. This vision entails large networks with dynamic connectivity, ad hoc formation and heterogeneous nodes. Central to be able to integrate all our lives to this massive virtual domain is security and privacy of the information that flows through it. […]

EWaste Collection

Lobby and Mezzanine, Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

We will be collecting EWASTE items in Levine Lobby on Tuesday in support of Energy Week @ Penn campaign. This is a great opportunity to properly recycle non-traditional items such as: computers & printers computer accessories (keyboards, mice) Monitors, TVs, Displays Mobile phones household electronics (anything with a plug!) light bulbs non-recyclable glass

MEAM Seminar: “Architecture in Biological Materials: A Template for Toughness Enhancement, or a Siren Song?”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Structural biological materials, such as animal bones and shells, display remarkable mechanical properties despite being composed of quite simple and ordinary constituent materials. For example, the toughness of nacre, a structural biological material found in the shells of some mollusks, is orders of magnitude higher than that of its primary constituent—the calcium based mineral aragonite. […]

CIS Seminar: “Learning in dynamic environments”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Abstract: In many online systems participants use data and algorithms to experiment and learn how to best use the system. Examples include traffic routing as well as online auctions. Game theory classically studies Nash equilibrium as the outcome of selfish interaction, and has many examples illustrating that selfish behavior can lead to suboptimal outcome for […]
