      The cost effective synthesis and patterning of carbon nanomaterials is a challenge in electronic and energy storage devices. Here we report a one-step, scalable approach for producing and patterning porous graphene films ...
    • A Lateral Flow Assay for Quantitative Detection of Amplified HIV-1 RNA 

      Rohrman, Brittany A.; Leautaud, Veronica; Molyneux, Elizabeth; Richards-Kortum, Rebecca R. (2012)
      Although the accessibility of HIV treatment in developing nations has increased dramatically over the past decade, viral load testing to monitor the response of patients receiving therapy is often unavailable. Existing ...
    • Lattice Algorithms for Compression Color Space Estimation in JPEG Images 

      Neelamani, Ramesh; de Queiroz, Ricardo; Baraniuk, Richard G. (2001-08-01)
      JPEG (Joint Photographic Experts Group) is an international standard to compress and store digital color images [5]. Given a color image that was previously JPEG-compressed in some hidden color space, we aim to estimate ...
    • Layered Dynamic Fault Detection and Tolerance for Robots 

      Visinsky, Monica L.; Walker, Ian D.; Cavallaro, Joseph R. (1993-05-01)
      Fault tolerance is increasingly important for space and hazardous environment robotics. Robots need to quickly detect and tolerate internal failures in order to continue performing their tasks without the need for immediate ...
