    November 05, 2019: Dr. Duong Viet Dung (VNU Univ. Eng. Tech.), Lagrangian Vortex Method for Complex Flow Simulation Applied in Aerospace, Wind, and Biology Engineering

    To solve complicated simulation problems for complex deforming objects under complicated motions found in aerospace, aerodynamics, meteorology, biology engineering, this seminar presents Lagrangian vortex method based on Brinkman penalization. The Brinkman penalization acts as an external force, which directly replaced in the Navier-Stokes equation, is described by velocity and vorticity. The advantage of the method is the capability to remove the pressure factor which causes errors in other numerical methods due to the complexity of the shape of the object. Besides, the method can model the complex geometry, complex motions as well as 3D deformation of the object. Then, the equation can be solved in a classical strategy: applying the Bio-Savart law formula is to deal with the convection process; the diffusion process can be solved by two methods: core spreading vortex method and particle strength exchange. The convergence is verified in several simulation applications such as airflow in rotation wings of a helicopter, side wings of UAV, the influence of stormwind on a high-raised building, and fish swimming.

    February 2, 2024: Dr. Khoa D. Doan (Vin Univeristy) Toward Reliable and Practical Machine Learning Applications

    While Machine Learning (ML) has rapidly transformed several domains and applications with incredible successes, there are also important areas where the progress is significantly slower. Specifically, there exists a widened complexity gap between the methods currently investigated in research and those used in practice in these areas. One reason is that many algorithms, despite achieving […]

    February 2, 2024: Prof. Heng Ji (University of Illinois at Urbana-Champaign), Combating with Misinformation and Cancer: A Unified Multimodal AI Approach to Healthy and Happy Life

    A research overview of ongoing research projects, especially focusing on two that are most related to the VinUni-UIUC Smart Health Center: (1) Misinformation Detection and Trustworthy Large Language Models; (2) Joint Natural Language and Molecule Learning for Drug Discovery. Unsurprisingly these two seemingly different research problems can be tackled with a unified approach based on […]

    January 11, 2024: Dr. Le Duc Trong (FIT-UET) Resilient Multimodal Learning for Multimodal Emotion Recognition in the Presence of Incomplete Modalities

    Multimodal Emotion Recognition in Conversation (Multimodal ERC) is a critical area of research for interpreting human communication in diverse applications. Nevertheless, the persistent issue of uncertain missing modalities poses a major hurdle, hampering the development of robust Multimodal ERC models. Existing approaches face limitations in effectively leveraging a fusion of diverse data modalities encompassing audio, […]
