      In this paper, we study power control to minimize packet loss for delay-bounded transmission of bursty sources over Gaussian channels and transmission of constant rate sources over time-varying block fading channels. In ...
    • Dual Wi-Fi: Dual Channel Wi-Fi for Congested WLANs with Asymmetric Traffic Loads 

      Flores Miranda, Adriana (2013-10-08)
      In many WLANs scenarios, the load transmitted from the AP to the clients (Downlink), far outweighs traffic demand from the clients to the AP (Uplink), thereby yielding traffic asymmetry. Moreover, when many clients associate ...
    • Dual-frequency modulation and range disambiguation in laser rangefinding systems 

      Melton, Darren (1994)
      Laser rangefinders, which measure distances by detecting the phase shift of intensity modulated laser light reflected by objects, are very useful for obtaining 3-D models of the surrounding environment. A drawback of ...

      Rostami, Masoud; Mohanram, Kartik (2011-03)
      This paper describes the electrode work-function, oxide thickness, gate-source/drain underlap, and silicon thickness optimization required to realize dual-Vth independent-gate FinFETs. Optimum values for these FinFET ...
    • Dyadic decision trees 

      Scott, Clayton (2004)
      This thesis introduces a new family of classifiers called dyadic decision trees (DDTs) and develops their theoretical properties within the framework of statistical learning theory. First, we show that DDTs achieve optimal ...
    • Dye-Assisted Gain of Strongly Confined Surface Plasmon Polaritons in Silver Nanowires 

      Paul, Aniruddha; Zhen, Yu-Rong; Wang, Yi; Chang, Wei-Shun; Xia, Younan; Nordlander, Peter; Link, Stephan (2014)
      Subwavelength confinement and active control of light is essential for nanoscale communication devices at visible frequencies that support large bandwidths.[1-5] Noble-metal nanostructures present an excellent platform for ...
    • Dynamic Cross Talk Model of the Epithelial Innate Immune Response to Double-Stranded RNA Stimulation: Coordinated Dynamics Emerging from Cell-Level Noise 

      Bertolusso, Roberto; Tian, Bing; Zhao, Yingxin; Vergara, Leoncio; Sabree, Aqeeb; Iwanaszko, Marta; Lipniacki, Tomasz; Brasier, Allan R.; Kimmel, Marek (2014)
      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 detection and intelligent fault tolerance for robotics 

      Visinsky, Monica Lynn (1994)
      As robotics has begun to spread from the accessible arenas of laboratories and industry into more dangerous and remote environments such as space or hazardous waste remediation tanks, the need for autonomous and intelligent ...
    • Dynamic Fault Reconfigurable Intelligent Control Architectures for Robotics 

      Cavallaro, Joseph R.; Walker, Ian D. (1993-04-01)

      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 ...
