    • Variability timescales in the M87 jet: signatures of E^2 losses, discovery of a quasi period in HST-1, and the site of TeV flaring 

      Harris, Daniel E.; Cheung, Chi C.; Stawarz, Łukasz; Biretta, J. A.; Perlman, Eric S. (2009-06-11)
      We investigate the variability timescales in the jet of M87 with two goals. The first is to use the rise times and decay times in the radio, ultraviolet, and X-ray light curves of HST-1 to constrain the source size and the ...
    • Variable-resolution video moire error map system for inspection of continuously manufactured objects 

      Blatt, Joel H.; Cahall, Scott C.; Hooker, Jeffery A. (1993-05-28)
      Moire techniques can be a powerful tool to determine deviation of a manufactured shape from a desired shape. In a traditional moire system, distorted gratings on an object are viewed through an undistorted grating. The ...
    • The Variation in the Occurrence of Diatoms in the External Mucus of Florida Sharks 

      Nakachi, Kaikea
      Elasmobranch skin has been extensively studied for its drag-reducing hydrodynamic structure and its implications for reduction in ship fuel cost1. Shark mucus and biofilm may also have antifouling properties of interest ...
    • Variational Lyapunov method and stability theory 

      Lakshmikantham, V.; Liu, Xinzhi; Leela, S. G (1998)
      By unifying the method of variation of parameters and Lyapunov's second method, we develop a fruitful technique which we call variational Lyapunov method. We then consider the stability theory in this new framework showing ...

    • Vasreactor 

      Boeringer, Tabitha; Estacio, Alvin; Hyland, Joan; Theus, Andrea
      Heart disease is the leading cause of death in the United States. There are numerous issues with finding healthy blood vessels in such patients, with them often having to return to surgery due to bypass failure. Bioreactors ...
    • Verification of precipitation forecasts from National Weather Service high resolution forecast models 

      Reardon, Kelly
      An evaluation of the High Resolution Rapid Refresh (HRRR) model and the Weather, Research, and Forecasting (WRF) model was conducted for the NWS in Melbourne, Florida. The models were verified through the radar precipitation ...
    • Video transmission over MIMO-OFDM system: MDC and space-time coding-based approaches 

      Zheng, Haifeng; Ru, Congchong; Chen, Changwen; Yu, Lun (2007)
      MIMO-OFDM is a promising technique for the broadband wireless communication system. In this paper, we propose a novel scheme that integrates multiple-description coding (MDC), error-resilient video coding, and unequal error ...
    • Virtual reality flight simulator : World War 

      Roig, Santiago; Zottola, Vincent
      The goal for this project is to create a Virtual Reality Flight Simulator that provides a high level of realism with a cost-effective approach. This software will allow pilots an opportunity to hone their skills with ...
    • Visible light responsive systems based on metastable-state photoacids 

      Liao, Yi (2015-08-13)
      Proton transfer is one of the most fundamental processes in nature. Metastable-state photoacids can reversibly generate a large proton concentration under visible light with moderate intensity. which provides a general ...
    • Visible-light activatable organic CO-releasing molecules (PhotoCORMs) that simultaneously generate fluorophores 

      Peng, Ping; Wang, Chaoming; Shi, Zheng; Johns, Valentine K.; Ma, Liyuan; Oyer, Jeremiah; Copik, Alicja; Igarashi, Robert; Liao, Yi (2013-07-31)
      Novel organic photoCORMs based on micelle-encapsulated unsaturated cyclic α-diketones were designed and synthesized. These photoCORMs can be activated by visible light, have potentially low toxicity, allow the delivery of ...
    • Visualization of medical images over mobile wireless handheld devices
