Though scallops can swim in the ocean by opening and closing their valves, the scallop theorem shows that this swimming mechanism would be ineffective in highly viscous conditions. In this regime, the Navier-Stokes equations linearize to give the Stokes equations. Since the Stokes equations are time-reversible, microorganisms have developed hair-like structures known as cilia in order to generate propulsion by breaking time-reversal symmetry. The squirmer model uses a slip velocity defined on the microswimmer surface to mimic the effect of beating cilia. There has been previous work on spherical and axisymmetric squirmers, but nature is not necessarily axisymmetric \u2013 thus, we explore microswimmers of arbitrary shape. We propose a framework for expressing the slip velocity on an arbitrary surface in terms of tangential basis functions. Using the reciprocal theorem, given a time-independent slip profile, we can determine the rigid body velocities and the resulting swimming trajectory for an isolated microswimmer suspended in free space.\r\n\r\n\r\nAt much larger length scales, flexible swimming sheets can be used to transport solar panels on water and can even model ice sheets on the ocean. In this regime, the inviscid Euler equations hold. Unlike the Stokes equations, the Euler equations are nonlinear and time-dependent. However, the boundary integral techniques that are commonly used in Stokes flow can also be used in this context to track the motion of the water-air interface. We will showcase preliminary results in which we test our numerical methods on linear and nonlinear water waves in the absence of a sheet. We will then discuss how the slithering motion of snakes can help us model the elastic sheets.", "occurrence_notes":null, "guid":"134953-21875725@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/134953", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"3088", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics","Applied Mathematics"], "website":"", "sponsors":[ { "group_name":"Student AIM Seminar - Department of Mathematics", "group_id":"4902", "website":"" }, { "group_name":"Department of Mathematics", "group_id":"3791", "website":"" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21875725 } , "134004-21873777": { "datetime_modified":"20250321T082635", "datetime_start":"20250416T160000", "datetime_end":"20250416T170000", "has_end_time":1, "date_start":"2025-04-16", "date_end":"2025-04-16", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"Ziwet Colloquium Lecture: Mathematical Analysis of Novel Advanced Materials: Epitaxy and Quantum Dots, Wetting and Dewetting", "occurrence_title":"", "combined_title":"Ziwet Colloquium Lecture: Mathematical Analysis of Novel Advanced Materials: Epitaxy and Quantum Dots, Wetting and Dewetting: Irene Fonesca (Carnegie Mellon University)", "event_subtitle":"Irene Fonesca (Carnegie Mellon University)", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Quantum dots are man-made nanocrystals of semiconducting materials. Their formation and assembly patterns play a central role in nanotechnology, and in particular in the optoelectronic properties of semiconductors. Changing the dots' size and shape gives rise to many applications that permeate our daily lives, such as the new Samsung QLED TV monitor that uses quantum dots to turn \"light into perfect color\"! \r\n\r\nQuantum dots are obtained via the deposition of a crystalline overlayer (epitaxial film) on a crystalline substrate. When the thickness of the film reaches a critical value, the profile of the film becomes corrugated and islands (quantum dots) form. As the creation of quantum dots evolves with time, materials defects appear. Their modelling is of great interest in materials science since material properties, including rigidity and conductivity, can be strongly influenced by the presence of defects such as dislocations. \r\n\r\nIn this talk, we will use methods from the calculus of variations and partial differential equations to model and mathematically analyze the onset of quantum dots, the regularity and evolution of their shapes, and the nucleation and motion of dislocations. Further, using the $H^{-1}$-gradient flow structure of the evolution law, short-time existence for a surface diffusion evolution equation with curvature regularization is established in the context of epitaxially strained two-dimensional films. The main novelty, as compared to the study of the wetting regime, is the presence of moving contact lines.", "occurrence_notes":null, "guid":"134004-21873777@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/134004", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"4448", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Lecture","seminar","Mathematics","Free"], "website":"https:\/\/lsa.umich.edu\/math\/seminars\/zwiet-lectures.html", "sponsors":[ { "group_name":"Colloquium Series - Department of Mathematics", "group_id":"4884", "website":"" }, { "group_name":"Department of Mathematics", "group_id":"3791", "website":"" }, { "group_name":"Special Events - Department of Mathematics", "group_id":"4912", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/03\/event_134004_original-1.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/03\/event_134004_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/03\/event_134004_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/03\/event_134004_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/03\/event_134004_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2025\/03\/event_134004_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2025\/03\/event_134004_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2025\/03\/event_134004_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/03\/event_134004_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2025\/03\/event_134004_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2025\/03\/event_134004_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/03\/event_134004_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/03\/event_134004_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2025\/03\/event_134004_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2025\/03\/event_134004_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/03\/event_134004_original-1.jpg" }, "occurrence_count":1, "first_occurrence":21873777 } , "135082-21876057": { "datetime_modified":"20250416T181557", "datetime_start":"20250416T163000", "datetime_end":"20250416T183000", "has_end_time":1, "date_start":"2025-04-16", "date_end":"2025-04-16", "time_start":"16:30:00", "time_end":"18:30:00", "time_zone":"America\/Detroit", "event_title":"Percussion Junior Recital", "occurrence_title":"", "combined_title":"Percussion Junior Recital", "event_subtitle":"", "event_type":"Performance", "event_type_id":"15", "description":"Junior students from the Percussion Studio perform a recital.", "occurrence_notes":null, "guid":"135082-21876057@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/135082", "building_id":"1000440", "building_name":"Earl V.
