  • Power Semiconductor Loss Modeling & Heat Sink Design for Submerged Power Electronics Within Hydrokinetic Applications

    Creator:
    Kilgore, Trenton L.
    Abstract:
    Hydrokinetic turbines are an emerging form of renewable energy generation. Although similar to wind turbines, hydrokinetic systems incur extra costs and face constraints in available footprint. SiC power semiconductors within the required power electronics improve the performance. With higher switching afforded by SiC devices, the footprint of passive components for...

  • A probabilistic framework and algorithms for modeling and analyzing multi-instance data

    Creator:
    Behmardi, Behrouz
    Abstract:
    Multi-instance data, in which each object (e.g., a document) is a collection of instances (e.g., word), are widespread in machine learning, signal processing, computer vision, bioinformatic, music, and social sciences. Existing probabilistic models, e.g., latent Dirichlet allocation (LDA), probabilistic latent semantic indexing (pLSI), and discrete component analysis (DCA), have been...
