  • Limits and Capabilities of Cooperative Diversity: A Network and Protocol Perspective 

    Bejarano Chavez, Oscar (2011)
    Physical-layer cooperation has been demonstrated to vastly improve wireless link reliability and end-to-end throughput by exploiting spatial diversity. Nevertheless, its performance in operational networking environments ...
  • Limits of acoustic waveguide communication 

    Sinanovic, Sinan (2006)
    A new method of wireless data telemetry in oil well services uses compressional acoustic waves to transmit data along the drill string. The compressional acoustic waves are produced as coded wave trains by an acoustic ...
  • Limits of population coding 

    Johnson, Don (2003-07-20)
    To understand whether the population response expresses information better than the aggregate of the individual responses, the sum of the individual contributions is frequently used as a baseline against which to assess ...
  • Linear finite memory-length multiuser detectors 

    Juntti, Markku J.; Aazhang, Behnaam (1995-10-20)
    Decorrelating, LMMSE, and the noise-whitening multiuser detectors for code division multiple access (CDMA) are ideally infinite memory length (IIR) detectors. To obtain more practical and robust systems linear finite ...
  • Linear Temporal Logic and Linear Dynamic Logic on Finite Traces 

    De Giacomo, Giuseppe; Vardi, Moshe Y. (2013)
    In this paper we look into the assumption of interpreting LTL over finite traces. In particular we show that LTLf, i.e., LTL under this assumption, is less expressive than what might appear at first sight, and that at ...
  • Liquid metal nanodroplet dynamics inside nanocontainers 

    Jung, Hyun Young; Chun, Hyunkyung; Park, Sora; Kang, Seoung-Hun; Ahn, Chi Won; Kwon, Young-Kyun; Upmanyu, Moneesh; Ajayan, Pulickel M.; Jung, Yung Joon (2013-09-05)
    Here we report direct observations of spatial movements of nanodroplets of Pb metal trapped inside sealed carbon nanocontainers. We find drastic changes in the mobility of the liquid droplets as the particle size increases ...
  • Lithium storage mechanisms in purpurin based organic lithium ion battery electrodes 

    Reddy, Arava Leela Mohana; Nagarajan, Subbiah; Chumyim, Porramate; Gowda, Sanketh R.; Pradhan, Padmanava; Jadhav, Swapnil R.; Dubey, Madan; John, George; Ajayan, Pulickel M. (2012-12-11)
    Current lithium batteries operate on inorganic insertion compounds to power a diverse range of applications, but recently there is a surging demand to develop environmentally friendly green electrode materials. To develop ...

    de Figueiredo, Rui J.P. (1975-07-20)
    As an extension of the notion of an <em>L-g</em> spline, three mathematical structures called <em>LM-g</em> splines of types, I, II and II are introduced. (partial abstract)
  • Local Error Analysis of Discontinuous Galerkin Methods for Advection-Dominated Elliptic Linear-Quadratic Optimal Control Problems 

    Leykekhman, Dmitriy; Heinkenschloss, Matthias (2012-08-15)
    This paper analyzes the local properties of the symmetric interior penalty upwind discontinuous Galerkin (SIPG) method for the numerical solution of optimal control problems governed by linear reaction-advection-diffusion ...
  • Locating Available Bandwidth Bottlenecks 

    Ribeiro, Vinay Joseph; Riedi, Rudolf H.; Baraniuk, Richard G. (2004-09-01)
    The Spatio-temporal Available Bandwidth estimator (STAB), a new edge-based probing tool, locates thin links --- those links with less available bandwidth than all links preceeding them --- on end-to-end network paths. By ...
  • Location-aided routing in intermittently connected networks 

    To, Khoa Anh (2005)
    One of the difficulties in achieving pervasive deployment of mobile ad hoc network routing protocols is their strong assumption regarding node connectivity. Many realistic networking scenarios fail to meet this assumption, ...
  • Location-oriented sampling 

    Singh, Prashant (2007)
    In this work we present a sampling scheme that uses feature-location information to compactly represent the data. Traditional Nyquist sampling leverages compact frequency support to form the representation, but it ignores ...
  • Long-Range Dependence: Now you see it now you don't! 

    Karagiannis , Thomas; Faloutsos , Michalis; Riedi, Rudolf H. (2002-11-20)
    Over the last few years, the network community has started to rely heavily on the use of novel concepts such as self-similarity and Long-Range Dependence (LRD). Despite their wide use, there is still much confusion regarding ...
  • Loss inference in unicast network tomography based on TCP traffic monitoring 

    Tsang, Yau-Yau Yolanda (2001)
    Network tomography is a promising technique for characterizing the internal behavior of large-scale networks based solely on end-to-end measurements. Despite the efficiency of active probing in most network loss tomography ...
