MSE Seminar: “Biomineralogical Signatures of Pathlogical Mineralization”

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

Pathological calcification is a wide-spread phenomenon in the human body, in which calcium minerals form in soft tissues and are found in both healthy and diseased tissues. One example are microcalcifications (MCs), which are primarily biological apatite and occur in cancerous and benign breast pathologies. MCs are key mammographic indicators, however, little is known about […]

Fall 2022 GRASP Seminar: Ankit Shah, Brown University, “Training Robots Like Apprentices”

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

*This is a HYBRID Event with in-person attendance in Levine 307 and virtual attendance via Zoom. ABSTRACT Domains such as high-mix manufacturing, domestic robotics, space exploration, etc., are key areas of interest for robotics. Yet, the difficulty of anticipating the role of robots in these domains is a crucial hurdle for the adoption of robots. […]

BE Seminar: “Cellular and Acellular Strategies for Heart and Lung Repair” (Ke Cheng, UNC/NCSU)

Glandt Forum, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

This is a hybrid seminar: Check email for the zoom link and passcode. "Cellular and Acellular Strategies for Heart and Lung Repair" Therapeutic tissue regeneration using stem cells has been hampered by the controversial identity of resident stem cells, low cell retention/engraftment, tumorigenecity and immunogenicity issues. Taking a bioengineering/biomaterials approach, this lecture will introduce the uses of drug delivery and biomaterials […]

Fall 2022 GRASP on Robotics: Matthew Johnson-Roberson, Carnegie Mellon University, “Lessons from the Field: Deep Learning and Machine Perception for field robots”

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

This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance via Zoom.   ABSTRACT Mobile robots now deliver vast amounts of sensor data from large unstructured environments. In attempting to process and interpret this data there are many unique challenges in bridging the gap between prerecorded data sets and the […]

PICS Seminar: “A Non-local Plasticity Model for Porous Metals with Deformation-induced Anisotropy: Mathematical and Computational Issues”

Zoom - Email MEAM for Link peterlit@seas.upenn.edu

A non-local (gradient) plasticity model for porous metals that accounts for deformation-induced anisotropy is presented. The model is based on the work of Ponte Castañeda and co-workers on porous materials containing randomly distributed ellipsoidal voids. It takes into account the evolution of porosity and the evolution/development of anisotropy due to changes in the shape and […]

MEAM Seminar: “Nonlinear Mechanical Behavior of Kirigami-inspired Architected Materials”

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

As 3D printing and other advanced manufacturing techniques have become more common, it is increasingly possible to produce structures with nearly arbitrary internal geometric and compositional features, opening up vast new design space for engineers. In this work, we consider a kirigami-inspired, flexible architected material comprising rotating squares joined at their vertices. The rotational degrees […]

Fall 2022 GRASP SFI: Harold Soh, National University of Singapore, “Towards Trustworthy Robots that Interact with People”

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

This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance via Zoom. ABSTRACT What will it take to develop robots that work with us in real-world tasks? In this talk, we’ll discuss some of our work across the autonomy stack of a robot as we make progress towards an answer. […]
