    • Distributed Protocols for Signal-Scale Cooperation 

      Hunter, Christopher R. (2012)
      Signal-scale cooperation is a class of techniques designed to harness the same gains offered by multi-antenna communication in scenarios where devices are too small to contain an array of antennas. While the potential ...
    • Distributed redundant representations in man-made and biological sensing systems 

      Rozell, Christopher John (2007)
      The ability of a man-made or biological system to understand its environment is limited by the methods used to process sensory information. In particular, the data representation is often a critical component of such ...
    • Distributed Resource Allocation with Local Information 

      Dash, Debashis (2013-12-09)
      Making distributed decisions based on incomplete information is inevitable in dynamic wireless networks due to a multitude of constraints. We study the effects of incomplete information on system performance in two parts. ...
    • Distributed scheduling and multi-channel opportunistic media access for ad hoc networks 

      Kanodia, Vikram (2004)
      Current wireless ad hoc networks suffer from two main performance limitations. First, current ad hoc networks do not efficiently utilize the scarce and dynamic wireless spectrum. As a result, the goodput of current ad hoc ...
    • Distributed Wavelet Transform for Irregular Sensor Network Grids 

      Wagner, Raymond; Choi, Hyeokho; Baraniuk, Richard G.; Delouille, Veronique (2005-07-01)
      Wavelet-based distributed data processing holds much promise for sensor networks; however, irregular sensor node placement precludes the direct application of standard wavelet techniques. In this paper, we develop a new ...
    • Diverging moments and parameter estimation 

      Goncalves, Paulo; Riedi, Rudolf H. (2004-01-15)
      Heavy tailed distributions enjoy increased popularity and become more readily applicable as the arsenal of analytical and numerical tools grows. They play key roles in modeling approaches in networking, finance, hydrology ...
    • DNA under Force: Mechanics, Electrostatics, and Hydration 

      Li, Jingqiang; Wijeratne, Sithara S.; Qiu, Xiangyun; Kiang, Ching-Hwa (2015)
      Quantifying the basic intra- and inter-molecular forces of DNA has helped us to better understand and further predict the behavior of DNA. Single molecule technique elucidates the mechanics of DNA under applied external ...
    • DOMAIN WALL VELOCITY IN MAGNETIC MATERIALS 

      BARTRAN, DAVID SAMUEL, JR. (1973)
    • Drug Target Optimization in Chronic Myeloid Leukemia Using Innovative Computational Platform 

      Chuang, Ryan; Hall, Benjamin A.; Benque, David; Cook, Byron; Ishtiaq, Samin; Piterman, Nir; Taylor, Alex; Vardi, Moshe; Koschmieder, Steffen; Gottgens, Berthold; Fisher, Jasmin (2015)
      Chronic Myeloid Leukemia (CML) represents a paradigm for the wider cancer field. Despite the fact that tyrosine kinase inhibitors have established targeted molecular therapy in CML, patients often face the risk of developing ...
    • DSP architectural considerations for optimal baseband processing 

      Rajagopal, Sridhar; Rixner, Scott; Cavallaro, Joseph R.; Aazhang, Behnaam (2002-08-20)
      The data rate requirements for future wireless systems has increased by orders-of-magnitude (from Kbps to several Mbps), requiring more sophisticated algorithms for their implementation. This tutorial will explore different ...

    • 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
