  • Novel Polymer Thin Films for Application in Flexible Organic Light-Emitting Diodes

    Wed, Sep 11, 2019, 11:10 am to 12:40 pm

    Abstract

    Organic light-emitting diodes (OLEDs) are films of organic molecules, 100s of nanometer thick, that emit light in response to an electric current. Thanks to their mechanical flexibility, they are fast replacing the traditional rigid devices with flexible ones; they include flexible mobile displays, TV displays, and even flexible lighting panels. Despite commercial success, OLED is still an active area of research. In particular, many scientists are working to develop new materials that lower the cost of production and increase OLED efficiency.

  • Wireless Networks via the Cloud: An Information Theoretic View

    Fri, Sep 6, 2019, 4:30 pm to 5:30 pm

    Abstract: Cloud based wireless networks named also as Cloud Radio Access Networks

    (C-RANs) emerge as appealing architectures for next-generation wireless/cellular systems whereby the processing/encoding/decoding is migrated from the local base-stations/radio units (RUs) to a control/central units (CU) in the "cloud".

    The network operates via fronthaul digital links connecting the CU and the RUs (operating as relays).

  • Beyond Supervised Learning for Biomedical Imaging

    Wed, Oct 2, 2019, 4:30 pm to 5:30 pm

    Abstract: Many biomedical imaging tasks, such as 3D reconstruction, denoising, detection, registration, and segmentation, are ill-posed inverse problems. In this talk, I will present a flexible machine learning-based framework that has allowed us to derive efficient solutions for a variety of such problems, without relying on heavy supervision. I will primarily employ image registration as a concrete application and present the details of VoxelMorph, our unsupervised learning-based image registration tool.
