As biometrics progresses from the lab into practical embedded applications, the need for systems that are computationally simple, memory efficient, and accurate becomes a priority. Polynomial classification systems have high potential to fit these requirements. Previous work has shown that polynomial techniques applied to speaker verification lead to accurate systems with simple multiply-add st...

and Applied Analysis 3 system. Secondly, do the solution operators for fractional evolution equations have the perturbation properties analogous to those for the C0-semigroup? For evolution equations of integer order, perturbation properties play a significant role in monotone iterative technique; see 24 . Our paper copes with the above difficulties, and the new features of this paper mainly in...

Recently, among the MIMO-OFDM detection techniques, a lot of papers suggested V-BLAST scheme which can achieve high data rate. Therefore, the signal detection of MIMO-OFDM system is important issue. In this paper, efficient iterative V-BLAST detection technique is proposed in wireless communication system. The proposed scheme adjusts the number of candidate symbol and iterative scheme based on ...

Various problems of pure and applied sciences can be studied in the unified frame work of the system of nonlinear equations. In this paper, a new family of iterative methods for solving a system of nonlinear equations is developed by using a new decomposition technique. The convergence of the new methods is proved. Efficiency index of the proposed methods is discussed and compared with some oth...

This paper presents an accurate and efficient full-wave method, combined with iterative adjoint technique, for analyzing sensitivities of planar microwave circuits with respect to design parameters. Method of moments (MoM) in spatial domain is utilized, and generalized conjugate residual iterative scheme is applied to solve the linear matrix equations with fast convergence. Green’s functions fo...

The spectral information of a Boolean function provides data regarding the correlation between the input variables and the output of the function. This paper introduces a spectral based methodology for com-binational logic synthesis using linear transforms. An analysis of the properties of the spectra obtained from these transforms is provided and a synthesis algorithm using spectral techniques...

Electron tomography (ET) is an important technique in biosciences that is providing new insights into the cellular ultrastructure. Iterative reconstruction methods have been shown to be robust against the noise and limited-tilt range conditions present in ET. Nevertheless, these methods are not extensively used due to their computational demands. Instead, the simpler method weighted backproject...

Global motion estimation is an important task in a variety of video processing applications, such as coding, segmentation, classificatiodindexing, and mosaicing. The main difficulty in global motion parameter estimation resides in the disturbances due to the independently moving objects. The Iterarive Leaf-Square Estimati’on (USE) technique [l] is commonly used in estimating a fourparameter mod...
