An algorithm for linear programming (LP) and convex quadratic programming (CQP) is proposed, based on an interior point iteration introduced more than ten years ago by J. Herskovits for the solution of nonlinear programming problems. Herskovits' iteration can be simpliied signiicantly in the LP/CQP case, and quadratic convergence from any initial point can be achieved. Interestingly the linear ...

In this paper we present a new efficient iterative nonlinear scheme for recovering of a piecewise constant image from an observed image containing additive noise. We apply an adaptive neighborhood filter which comes from robust statistics and completely rejects outliers being greater than a certain constant. We prove that the iterated application of the scheme leads to a piecewise constant imag...

We propose a new approach to reduce speckle noise and enhance structures in speckle-corrupted images. It utilizes a mediananisotropic diffusion compound scheme. The median-filter-based reaction term acts as a guided energy source to boost the structures in the image being processed. In addition, it regularizes the diffusion equation to ensure the existence and uniqueness of a solution. We also ...

In this paper, we propose an iterative detection and decoding (IDD) scheme for the uplink of coded multiuser multiple-input multiple-output (MU-MIMO) systems. The structure of the proposed soft-input soft-output (SISO) iterative (turbo) scheme is based on a multi-branch lattice reduction successive interference cancellation (MB-LR-SIC) strategy that computes in the first iteration a reliable ex...

By principal motivation from the results of new iterative scheme that produces faster than K-iteration. In this article, we study generalized by a iteration to approximate fixed points contraction and Suzuki non-expansive mappings. We establish strong convergence mappings closed convex Banach space also deduce data dependent results. Furthermore, prove some weak theorems in sense mapping applyi...

We propose a class of numerical schemes for nonlocal HJB variational inequalities (HJBVIs) with monotone nonlinearities arising from mixed optimal stopping and control processes infinite activity jumps, where the objective is specified by recursive preference. The solution free boundary HJBVI are constructed sequence penalized equations, which penalization error estimated. equation then discret...

This work proposes a new rotation mode CORDIC algorithm, which considerably reduces the iteration number. It is achieved by combining several design techniques. Particularly, a new table-lookup recoding scheme for rotation angles and variable scale factors is developed to reduce the iteration numbers for rotation and scale factor compensation. By addressing the MSB parts of the residual rotatio...
