Focusing properties of the radially polarized Bessel–Gauss beam with a sine-azimuthal variation wavefront was investigated by the vector diffraction theory. The wavefront distribution is the sine function of the azimuthal angle with one phase parameter that indicates the phase change frequency. Results show that the focal pattern can be altered by the phase parameter, and many novel focal patte...

parameter estimation is an important task in the modeling, classification, and detection of radar clutters. radar clutters have stochastic characteristics. therefore, statistical distributions are usually used to describe the features of clutters better. k distribution is one of the most common models utilized to the simulation of clutters. this distribution, which consists of scale and shape p...

3D Shape modeling has been a very prominent part of Computer Vision over the past decade. Several shape modeling techniques have been proposed in literature, some are local (distributed parameter) while others are global (lumped parameter) in terms of the parameters required to describe the shape. Hybrid models that combine both ends of this parameter spectrum have been in vogue only recently. ...

The glottal shape parameter Rd provides a onedimensional parameterisation of the Liljencrants-Fant (LF) model which describes the deterministic component of the glottal source. In this paper we first propose to estimate the Rd parameter by means of extending a state-ofthe-art method based on the phase minimization criterion. Then we propose an adaption of the standard Rd parameter regression wh...
