During the workshop, we will review and explain the main steps of a machine learning-based computer vision project, from problem definition to image acquisition, annotation, training, validation, and inference. We will illustrate these steps in a practical way, by building a real computer vision application together until we can run it live on a camera. Along the way, we will discuss important concepts (data drift, overfitting, data augmentation) and observe how they manifest themselves in practice. We will also share tips and tricks to help you tackle your own computer vision challenges.<br>\r\n<br>\r\n<strong>Prerequisites:</strong><br>\r\nBasic familiarity with Python, image analysis, and machine learning concepts is desirable, but not strictly necessary.<br>\r\n<br>\r\n<strong>Level:</strong> <br>\r\nBeginner / Intermediate<br>\r\n ", "image_description": "", "creation_date": "2026-01-30T11:40:06", "last_modification_date": "2026-01-30T11:40:06", "link_label": "Registration", "link_url": "https://docs.google.com/forms/d/e/1FAIpQLSc1NukuuzIzzMnbDZkfudvj1M7wDJY6JeWQKoQrcl1ZIVFcUw/viewform?usp=header", "canceled": "False", "cancel_reason": "", "place_and_room": "CE 1 711.2", "url_place_and_room": "https://plan.epfl.ch/?room==CE%201%20711.2", "url_online_room": "", "spoken_languages": [ "https://memento.epfl.ch/api/v1/spoken_languages/2/?format=api" ], "speaker": "<a href=\"https://people.epfl.ch/mallory.wittwer?lang=en\">Mallory Witwer</a>", "organizer": "<a href=\"https://imaging.epfl.ch/\">Center for Imaging</a>", "contact": "<a href=\"https://people.epfl.ch/cecilia.carron?lang=fr\">Cecilia Carron</a>", "is_internal": "False", "theme": "", "vulgarization": { "id": 1, "fr_label": "Tout public", "en_label": "General public" }, "registration": { "id": 1, "fr_label": "Sur inscription", "en_label": "Registration required" }, "keywords": "", "file": null, "icalendar_url": "https://memento.epfl.ch/event/export/119528/", "category": { "id": 1, "code": "CONF", "fr_label": "Conférences - Séminaires", "en_label": "Conferences - Seminars", "activated": true }, "academic_calendar_category": null, "domains": [], "mementos": [ "https://memento.epfl.ch/api/v1/mementos/1/?format=api", "https://memento.epfl.ch/api/v1/mementos/4/?format=api", "https://memento.epfl.ch/api/v1/mementos/5/?format=api", "https://memento.epfl.ch/api/v1/mementos/6/?format=api", "https://memento.epfl.ch/api/v1/mementos/8/?format=api", "https://memento.epfl.ch/api/v1/mementos/9/?format=api", "https://memento.epfl.ch/api/v1/mementos/284/?format=api", "https://memento.epfl.ch/api/v1/mementos/27/?format=api" ] }, { "id": 71229, "title": "MechE Colloquium: Functional materials for renewable energy storage and conversion – sustainable and scalable materials design for photocatalysts and battery materials", "slug": "meche-colloquium-functional-materials-for-renewabl", "event_url": "https://memento.epfl.ch/event/meche-colloquium-functional-materials-for-renewabl", "visual_url": "https://memento.epfl.ch/image/32590/200x112.jpg", "visual_large_url": "https://memento.epfl.ch/image/32590/720x405.jpg", "visual_maxsize_url": "https://memento.epfl.ch/image/32590/max-size.jpg", "lang": "en", "start_date": "2026-04-07", "end_date": "2026-04-07", "start_time": "12:00:00", "end_time": "13:00:00", "description": "<strong>Abstract: </strong>Renewable energy conversion and storage are pressing topics in applied research today, as the use of non-fossil energy sources is essential to reduce CO<sub>2</sub> emissions. Solar and wind energy harvesting combined with chemical energy storage in batteries or fuels, such as hydrogen, are essential processes, that need to be improved in terms of efficiency, long-term stability, scalability and sustainability. Although significant progress has been made, many proposed photo- or electrochemical devices show satisfying short-term efficiencies in the laboratory but are too cost-intensive, too unstable and/or not sustainable enough for large-scale applications [1][2]. This is often the case, because they rely on rare materials and/or they are not fabricated using scalable processes. From a material science point of view, key areas to improve dynamic processes include, of course, the bulk properties of the active materials themselves, as well as the interfaces between the active materials and the electrolyte [3]. <br>\r\nIn this contribution concepts are presented how to improve the function of active materials in photo- or electrochemical energy applications by materials and interface design while respecting sustainability criteria. Our strategies include morphology control by scalable synthesis procedures and chemical modifications using earth-abundant and sustainable additives. These approaches are showcased in two application areas: photocatalysis for solar water-splitting and post-lithium-ion batteries. In both cases vanadium-based chemistries and low energy hydrothermal synthesis processes are used to produce devices with improved function [4,5].<br>\r\n[1] A. Vilanova, P. Dias, T. Lopes and A.

Historically, research has primarily focused on predicting the onset of buckling—that is, the loss of the original configuration under excessive loading—rather than on understanding how structures evolve in the post-buckling regime. Recently, however, the study of buckling has experienced a renaissance, with post-buckling mechanical responses increasingly exploited to achieve new functionalities, for example enhancing fracture resistance in stretchable electronics and flexible displays.<br>\r\n<br>\r\nWhile most existing studies consider elastically deforming systems whose behaviour arises primarily from geometric nonlinearities, this talk presents examples in which geometric effects are coupled with nonlinear constitutive responses, giving rise to new post-buckling mechanisms. First, we investigate the buckling of hard, perforated (“holey”) structures that exhibit auxetic behaviour but, unlike their purely elastic counterparts, undergo post-buckling softening. The resulting negative stiffness is captured using a pseudo-plastic constitutive model that describes nonlinearities emerging from the structural microarchitecture.<br>\r\n<br>\r\nWe then apply a similar framework to examine the buckling of beverage cans largely filled with liquid under axial compression. Whereas empty cylindrical shells typically develop periodic buckling patterns that break both axial and circumferential symmetry, liquid-filled cylinders buckle axisymmetrically. The resulting ring-shaped buckles are localized and emerge sequentially, progressively covering the can surface. We show that this behaviour arises from nonlinear, spatially anisotropic hoop stresses that soften and subsequently re-stiffen during compression.<br>\r\n<br>\r\n<strong>Biography: </strong>Draga Pihler-Puzovic is a Reader in the Department of Physics and Astronomy at the University of Manchester and a core member of the Manchester Centre for Nonlinear Dynamics.

Their stability and eventual breakdown influence wake dynamics, mixing processes, and overall flow performance. This seminar presents two recent studies exploring vortex stability and vortex breakdown.<br>\r\nPart I – Short-wave instability of a helical vortex<br>\r\nThe first part of the seminar discusses the short-wave instability of a helical vortex generated by a rotating blade. Combining experimental dye visualisations, numerical simulations, and theoretical analysis, the study identifies displacement perturbations whose wavelengths are small relative to the helix radius and pitch but may remain large compared with the vortex core size. Stability analysis based on experimentally measured vortex profiles reveals broad bands of unstable wavenumbers for several vortex bending modes. These results differ from predictions of existing theories for short-wave vortex instability. Similar instability modes are also observed in arrays of straight vortices, indicating that the phenomenon is not related to vortex curvature. A theoretical examination of the dispersion relation of Kelvin modes for the measured vortex profiles uncovers a previously unidentified family of modes associated with the specific vorticity distribution. Their non-resonant interaction through the strain field provides a plausible explanation for the experimentally observed instability features.<br>\r\nPart II – Two-phase wing-tip vortex breakdown<br>\r\nThe second part presents the discovery of a new flow feature observed in the wake of a rectangular wing in water: the breakdown of the wing-tip vortex triggered by the injection of air into the vortex core downstream of the wing. Experiments show that, for certain combinations of Reynolds number and angle of attack, a stationary air bubble becomes trapped within the vortex core at a finite distance behind the wing and can persist for several minutes even after the air injection is stopped. Under different conditions, the bubble may drift upstream or downstream, or it may disintegrate immediately. Measurements of bubble properties and vortex characteristics reveal that the breakdown behaviour depends primarily on the vortex circulation and on the axial flow component within the core. The formation of a stable breakdown bubble occurs only when a velocity excess relative to the free stream is present.<br>\r\nThe two studies highlight new mechanisms governing the stability and transformation of vortical flows, offering insight into the dynamics of vortex instabilities and vortex-core modifications in fluid systems.<br>\r\n<br>\r\n<br>\r\n<strong>Biography</strong><br>\r\nThomas Leweke graduated from RWTH Aachen University in Germany in 1990 with a “Diplom” (Master) in Physics.
