A New Representation of Distorted Wave Forms

The Generalized Wave Model Representation of Singular 2-D Systems

    M. and M.   Abstract: Existence and uniqueness of solution for singular 2-D systems depends on regularity condition. Simple regularity implies regularity and under this assumption, the generalized wave model (GWM) is introduced to cast singular 2-D system of equations as a family of non-singular 1-D models with variable structure.These index dependent models, along with a set of boundary co...

A phase-compensated distorted wave Born approximation representation of the bistatic scattering by weakly scattering objects: Application to zooplankton

The distorted wave Born approximation ~DWBA! method has been successfully used in modeling the acoustic backscattering by weakly scattering zooplankton @Stanton et al., J. Acoust. Soc. Am. 94, 3463–3472 ~1993!, Wiebe et al., IEEE J. Ocean. Eng. 22~3!, 445–464 ~1997!#. However, the previously developed DWBA model ignores the imaginary part of the scattering amplitude and thus results in a zero-e...

Time perception in spatial neglect: a distorted representation?

OBJECTIVE It has been proposed that time, space, and numbers share the same metrics and cortical network, the right parietal cortex. Several recent investigations have demonstrated that the mental number line representation is distorted in neglect patients. The aim of this study is to investigate the relationship between time and spatial configuration in neglect patients. METHOD Fourteen righ...

A New IRIS Segmentation Method Based on Sparse Representation

Iris recognition is one of the most reliable methods for identification. In general, itconsists of image acquisition, iris segmentation, feature extraction and matching. Among them, iris segmentation has an important role on the performance of any iris recognition system. Eyes nonlinear movement, occlusion, and specular reflection are main challenges for any iris segmentation method. In thi...
