  • Research on the Fundamental Principles and Characteristics of Correspondence Function 

    Li, Xiangru; Wang, Guanghui; Wu, Q.M. Jonathan (Hindawi Publishing Corporation, 2015)
    The correspondence function (CF) is a concept recently introduced to reject the mismatches from given putative correspondences. The fundamental idea of the CF is that the relationship of some corresponding points between ...
  • Shaping light beams in the nanometer scale: A Yagi-Uda nanoantenna in the optical domain 

    Li, Jingjing; Salandrino, Alessandro; Engheta, Nader (American Physical Society, 2007-12-06)
    A Yagi-Uda-like optical nanoantenna concept using resonant core-shell plasmonic particles as its “reflectors” and “directors” is studied numerically. Such particles when placed near an optical dipole source in a certain ...

    Salandrino, Alessandro; Engheta, Nader (American Physical Society, 2006-08-15)
    Here we suggest and explore theoretically an idea for a far-field scanless optical microscopy with a subdiffraction resolution. We exploit the special dispersion characteristics of an anisotropic metamaterial crystal that ...
  • Epsilon-near-zero metamaterials and electromagnetic sources: Tailoring the radiation phase pattern 

    Alù, Andrea; Silveirinha, Mário G.; Salandrino, Alessandro; Engheta, Nader (American Physical Society, 2007-04-11)
    In this work, we investigate the response of epsilon-near-zero metamaterials and plasmonic materials to electromagnetic source excitation. The use of these media for tailoring the phase of radiation pattern of arbitrary ...
  • A Convolve-And-MErge Approach for Exact Computations on High-Performance Reconfigurable Computers 

    El-Araby, Esam; Gonzalez, Ivan; Lopez-Buedo, Sergio; El-Ghazawi, Tarek (Hindawi Publishing Corporation, 2012-02)
    This work presents an approach for accelerating arbitrary-precision arithmetic on high-performance reconfigurable computers (HPRCs). Although faster and smaller, fixed-precision arithmetic has inherent rounding and overflow ...
  • Dynamic RACH Partition for Massive Access of Differentiated M2M Services 

    Du, Qinghe; Li, Wanyu; Liu, Lingjia; Ren, Pinyi; Wang, Yichen; Sun, Li (Multidisciplinary Digital Publishing Institute, 2016-03-30)
    In machine-to-machine (M2M) networks, a key challenge is to overcome the overload problem caused by random access requests from massive machine-type communication (MTC) devices. When differentiated services coexist, such ...
  • Algebraic Error Based Triangulation and Metric of Lines 

    Wu, Fuchao; Zhang, Ming; Wang, Guanghui; Hu, Zhanyi (Public Library of Science, 2015-07-28)
    Line triangulation, a classical geometric problem in computer vision, is to determine the 3D coordinates of a line based on its 2D image projections from more than two views of cameras with known projection matrices. ...

  • A Multi-Agent Approach to the Game of Go Using Genetic Algorithms 

    Blackman, Todd; Agah, Arvin (De Gruyter, 2011)
    Many researchers have written or attempted to write programs that play the ancient Chinese board game called Go. Although some programs play the game quite well compared with beginners, few play extremely well, and none ...
  • Design and Simulation of a Polar Mobile Robot 

    Akers, Eric L.; Agah, Arvin (De Gruyter, 2008)
