The study of the early universe requires deep high-resolution maps of the sky at millimeter and submillimeter. This requires the development of state-of-the-art cryogenic receivers and custom built telescopes. These instruments operate in extreme locations including from NASA launched high-altitude balloons over Antarctica and high (5,200m/17,000ft) mountain tops in Northern Chile adding a level of […] |

Nanolattices exhibit attractive mechanical, energy conversion, and optical properties, but it is challenging to fabricate nanolattices in large scale while maintaining the dense hierarchical nanometer features that enable their properties. Current advanced fabrication methods, like 3D printing or self-assembly, are significantly limited by their scalability or the cracking problem in the assembled templates. This work […]

ABSTRACT Traditional convolutional networks exhibit unprecedented robustness to intraclass nuisances when trained on big data. Generalization with respect to geometric transformations has been achieved via expensive data augmentation. It has been shown recently that data augmentation can be avoided if networks are structured such that feature representations are transformed the same way as the input, a desirable property called equivariance. In […]

Different from neuron-based computational intelligence through the brain, physical intelligence leverages structural designs and smart materials to physically encode sensing, actuation, control, adaption, and decision-making into the body of an agent. The stimuli-responsive body materials can enable autonomous sensory, actuation, powering, and other physical intelligence functions. The structural designs of soft body can simplify the […] |

Abstract Sensing and actuation systems are entrusted with increasing intelligence to perceive the environment and react to it. Their reliability often relies on the trustworthiness of sensors. As process automation and robotics keep evolving, sensing methods such as pressure/temperature/motion sensing are extensively used in conventional systems and rapidly emerging applications. This talk aims to investigate […] |

If you are finishing your PhD or your postdoctoral tenure you may be asking yourself, What’s next? Should I pursue an academic career, as my thesis adviser or postdoctoral supervisor has done? Or should I look elsewhere, perhaps at industry, or government? These are great questions that most of us have asked ourselves at the […]

This is a hybrid seminar that will take place in Glandt Forum (Singh Center) and via Zoom (check email for link and passcode). Our lab seeks to understand the neural basis of complex spatial, acoustic and social behaviors in mammals. To do so, we take a neuroethological approach that leverages the specialization of the bat […] |

Abstract: Recently, the transfer learning paradigm has seen a surge of interest due to its impressive capabilities in vision and language. Models are pretrained on ever-growing datasets with enormous parameter counts, trending towards being monolithic and opaque. How can we understand the underlying process? This talk will provide, to some degree, insight on how data […]

This is a hybrid event with in-person attendance in Levine 307 and virtual attendance via Zoom. ABSTRACT Reliable operation in everyday human environments – homes, offices, and businesses – remains elusive for today’s robotic systems. A key challenge is diversity, as no two homes or businesses are exactly alike. However, despite the innumerable unique aspects […] |

The increasing demand for structural metals has driven increasingly complex compositions, which bring critical challenges in processing of these materials. Additive manufacturing, also called 3D printing, is a disruptive technology for creating structural materials and components in a single print. In this talk, I will present our recent work on additive manufacturing of compositionally complex […] |

Exergy-based methods are powerful tools for developing, evaluating, understanding, and improving energy conversion systems. In addition to conventional methods, advanced exergy-based analyses consider (a) the interactions among components of the overall system, and (b) the real potential for improving each important system component. The main role of an advanced analysis is to provide energy conversion […]

ABSTRACT: Machine learning systems, in virtually every deployed system, encounter data from a qualitatively different distribution than what they were trained upon. Effectively dealing with this problem, known as domain shift, is thus perhaps the key challenge in deploying machine learning methods in practice. In this talk, I will motivate some of these challenges in […] |

Curvature is the common driving force for grain boundary motion in all polycrystals. However, models and simulations derived from curvature-based motion cannot predict irregular, albeit commonly observed, grain growth behavior. To build better predictive models, we need to employ new tools to understand what governs grain growth. First, I will demonstrate how high energy x-ray […] |

The intense noise radiated by supersonic jets leads to sound-induced structural vibration, fatigue and personnel-related operational difficulties. Experimental, theoretical, and computational investigations into the physics and control of jet noise have identified several important sound sources, including wavepackets, screech, Mach wave radiation, and broadband shock associated noise. Reducing the loudest sources of jet noise, without […] |

In recent years polymer chemists have made tremendous strides in the synthesis of biocompatible, tough, self-healing hydrogels. However, there are not many comprehensive mechanical models that capture the observed time dependent mechanical behavior of these gels (especially fracture) to the underlying, rate dependent bond breaking and reformation processes. In this talk I will summarize some […] |
