    Bertolusso, Roberto; Tian, Bing; Zhao, Yingxin; Vergara, Leoncio; Sabree, Aqeeb; Iwanaszko, Marta; Lipniacki, Tomasz; Brasier, Allan R.; Kimmel, Marek (2014-04-07)
    We present an integrated dynamical cross-talk model of the epithelial innate immune reponse (IIR) incorporating RIG-I and TLR3 as the two major pattern recognition receptors (PRR) converging on the RelA and IRF3 transcriptional ...
  • Dynamic Fault Reconfigurable Intelligent Control Architectures for Robotics 

    Cavallaro, Joseph R.; Walker, Ian D. (1993-04-01)
    In this paper we describe new progress in our development of an Intelligent Control Framework for robots which dynamically reconfigures itself to cope with faults in either sensors or joint hardware. The Framework is ...
  • A Dynamic Fault Tolerance Framework for Remote Robots 

    Visinsky, Monica L.; Cavallaro, Joseph R.; Walker, Ian D. (1995-08-01)
    Fault tolerance is increasingly important for robots, especially those in remote or hazardous environments. Robots need the ability to effectively detect and tolerate internal failures in order to continue performing their ...
  • Dynamic Franz-Keldysh effect and its applications 

    Srivastava, Ajit (2003)
    In this dissertation we study the dynamic Franz-Keldysh effect (DFKE) in GaAs. We observe the salient features of DFKE viz., below bandgap absorption and oscillations above the band gap, in our experiments. We also report ...
  • Dynamic Lateral Stability of Elastomeric Seismic 2 Isolation Bearings 

    Vemuru, V.; Nagarajaiah, S.; Masroor, A.; Mosqueda, G. (2014)
    Predicting the response of elastomeric seismic isolation bearings when subjected to severe ground motions is challenging due to the highly nonlinear behavior associated with the bearings under a combination of large ...
  • Dynamic Memory Interconnections for Rapid Access 

    Iyer, Bala; Sinclair, J. Bartlett (1980-11-01)
    Certain aspects of bulk storage technology development have required the study of dynamic memory interconnections. Various schemes to interconnect physical storage locations have been proposed in the literature. Taking ...
  • DYNAMIC REASSIGNMENT IN DISTRIBUTED PROCESSING SYSTEMS 

    SINCLAIR, JAMES BARTLETT (1979)
  • Dynamic Self-Stiffening in Liquid Crystal Elastomers 

    Agrawal, Aditya; Chipara, Alin C.; Shamoo, Yousif; Patra, Prabir K.; Carey, Brent J.; Ajayan, Pulickel M.; Chapman, Walter G.; Verduzco, Rafael (2013)
    Biological tissues have the remarkable ability to remodel and repair in response to disease, injury and mechanical stresses. Synthetic materials lack the complexity of biological tissues, and man-made materials that respond ...
  • Dynamic Senor-Based Fault Detection for Robots 

    Visinsky, Monica L.; Cavallaro, Joseph R.; Walker, Ian D. (1993-09-01)
    Fault detection and fault tolerance are increasingly important for robots in space or hazardous environments due to the dangerous and often inaccessible nature of these environs. We have previously developed algorithms to ...
  • Dynamically reconfigurable data caches in low-power computing 

    Brogioli, Michael C. (2003)
    In order to curb microprocessor power consumption, we propose an L1 data cache which can be reconfigured dynamically at runtime according to the cache requirements of a given application. A two phase approach is used ...
  • Edge Characteristics in Wavelet-Based Image Coding 

    Wakin, Michael (2001-04-20)
    Accurate prediction of wavelet coefficients relies on an understanding of the phase effects of edge alignment. This research examines techniques for uncovering edge information based on the available coefficients. These ...
  • Edge Guided Reconstruction for Compressive Imaging 

    Guo, Weihong; Yin, Wotao (2012-07-03)
    We propose EdgeCS—an edge guided compressive sensing reconstruction approach—to recover images of higher quality from fewer measurements than the current methods. Edges are important image features that are used in various ...
  • Edge Localized Image Sharpening via Reassignment with Application to Computed Tomography 

    Dorney, Timothy D.; Bhashyam, Srikrishna; Doran, Andrew; Choi, Hyeokho; Flandrin, Patrick; Baraniuk, Richard G. (2000-07-01)
    Traditional filtering methods operate on the entire signal or image. In some applications, however, errors are concentrated in specific regions or features. A prime example is images generated using computed tomography. ...
  • Edge-based inference, control, and DoS resilience for the Internet 

    Kuzmanovic, Aleksandar (2004)
    Realizing new services on the Internet ultimately requires edge-based solutions for both deployability and scalability. Each such solution has two fundamental aspects. The first is the ability to accurately infer critical ...
  • EDIF netlist optimization of pipelined designs 

    Balabanos, Vasileios (2000)
