  • Subnet discovery in passive internally sensed network tomography 

    King, Ryan C. (2007)
    Passive internally-sensed network tomography is the study of network characteristics and behavior based on observations of network traffic on a select subset of links inside the network. In this research, we identify the ...
  • Subradiant, superradiant and Fano resonances in dimer and ring/disk nanocavities 

    Sobhani Khakestar, Heidar (2010)
    Subradiant and superradiant plasmon modes in ring/disk nanocavities and dialers are investigated theoretically and experimentally. The subradiance is obtained through an overall reduction of the total dipole moment of the ...
  • Subspace-based channel estimation for code division multiple access communication systems 

    Bensley, Stephen E; Aazhang, Behnaam (1996-08-20)
    We consider the estimation of channel parameters for code-division multiple access (CDMA) communication systems operating over channels with either single or multiple propagation paths. The multiuser channel estimation ...
  • Subspace-based Tracking of Multipath Channel Parameters for CDMA Systems 

    Sengupta, Chaitali; Cavallaro, Joseph R.; Aazhang, Behnaam (1998-09-20)
    In this paper, we evaluate several issues in the application of subspace based methods to tracking channel parameters in Code Division Multiple Access (CDMA) communication systems, in the presence of multipath fading. We ...
  • Super-Resolution mbPAINT for Optical Localization of Single-Stranded DNA 

    Chen, Jixin; Bremauntz, Alberto; Kisley, Lydia; Shuang, Bo; Landes, Christy F. (2013)
    We demonstrate the application of superlocalization microscopy to identify sequence-specific portions of single-stranded DNA (ssDNA) with sequence resolution of 50 nucleotides, corresponding to a spatial resolution of 30 ...

    Chen, Jixin; Bremauntz, Alberto; Kisley, Lydia; Shuang, Bo; Landes, Christy F. (2013)
    We demonstrate the application of superlocalization microscopy to identify sequence-specific portions of single-stranded DNA (ssDNA) with sequence resolution of 50 nucleotides, corresponding to a spatial resolution of 30 ...
  • Supporting vehicular mobility in urban multi-hop wireless networks 

    Giannoulis, Anastasios (2009)
    Deployments of city-wide multi-hop 802.11 networks introduce challenges for maintaining client performance at vehicular speeds. In this thesis, we experimentally demonstrate that current network interfaces employ policies ...
  • Surface enhanced Raman scattering with metal nanoshells 

    Jackson, Joseph Bryan (2004)
    A systematic investigation of surface enhanced Raman scattering (SERS) was performed using metal nanoshells as the substrate. Nanoshells are a dielectric sphere coated with a thin metal shell, which have a well understood, ...
  • Surflets: A Sparse Representation for Multidimensional Functions Containing Smooth Discontinuities 

    Chandrasekaran, Venkat; Wakin, Michael; Baron, Dror; Baraniuk, Richard G. (2004-07-01)
    Discontinuities in data often provide vital information, and representing these discontinuities sparsely is an important goal for approximation and compression algorithms. Little work has been done on efficient representations ...
  • The Surprising in Vivo Instability of Near-IR-Absorbing Hollow Au-Ag Nanoshells 

    Goodman, Amanda M.; Cao, Yang; Urban, Cordula; Neumann, Oara; Ayala-Orozco, Ciceron; Knight, Mark W.; Joshi, Amit; Nordlander, Peter; Halas, Naomi J. (2014)
    Photothermal ablation based on resonant illumination of near-infrared-absorbing noble metal nanoparticles that have accumulated in tumors is a highly promising cancer therapy, currently in multiple clinical trials. A crucial ...
  • A Survey of NASA and Military Standards on Fault Tolerance and Reliability Applied to Robotics 

    Cavallaro, Joseph R.; Walker, Ian D. (1994-03-01)
    There is currently increasing interest and activity in the area of reliability and fault tolerance for robotics. This paper discusses the application of Standards in robot reliability, and surveys the literature of relevant ...
  • SWIR Imaging and Echelle Spectroscopy via Compressive Sensing 

    Xu, Lina (2012)
    A new sampling theory, called compressive sensing (CS), has recently emerged and its fundamental idea can be distilled as: it is possible to obtain near complete recovery of a signal/image from a small set of mixed ...
  • Symmetrizing the Kullback-Leibler Distance 

    Johnson, Don; Sinanovic, Sinan (2001-03-20)
    We define a new distance measure - the resistor-average distance - between two probability distributions that is closely related to the Kullback-Leibler distance. While the Kullback-Leibler distance is asymmetric in the ...
  • Synthesis of Linear Multivariable Regulators 

    Cheng, Lin-Fu; Pearson, J.B. (1980-02-01)
    This paper generalizes the results obtained by the authors in [1] and presents new results on the construction of proper controllers for linear multivariable regulators. These results appear to lead to efficient computational ...
  • SYNTHESIS OF OPTIMAL CONTROL SYSTEMS WITH STABLE FEEDBACK 

    GANESH, CHIDAMBAR (1987)
    In this thesis, the question of optimal control system design when constrained to using a stable controller is addressed. The performance index that is minimized is H$\sp\infty$-norm of the sensitivity of the closed-loop ...
