Strong Convergent Theorems Governed by Pseudo-Monotone Mappings

open access: yesMathematics, 2020
The purpose of this paper is to introduce two different kinds of iterative algorithms with inertial effects for solving variational inequalities. The iterative processes are based on the extragradient method, the Mann-type method and the viscosity method.

Comparison of non-crossing perturbative approach and generalized projection method for strongly coupled spin-fermion systems at low doping

open access: yes, 1998
We analyze the two-dimensional spin-fermion model in the strong coupling regime relevant to underdoped cuprates. We recall the set of general sumrules that relate moments of spectral density and the imaginary part of fermion self-energy with static ...

String-Averaging Projected Subgradient Methods for Constrained Minimization [PDF]

open access: yes, 2013
We consider constrained minimization problems and propose to replace the projection onto the entire feasible region, required in the Projected Subgradient Method (PSM), by projections onto the individual sets whose intersection forms the entire feasible ...

Mathematical modeling of diffraction of tem-wave on the periodic 2D structures of graphene micro-ribbons with finite length at terahertz frequency range

open access: yesФизика волновых процессов и радиотехнические системы, 2014
The mathematical simulation of diffraction of TEM-wave on the periodic 2D structures of graphene micro-ribbons with finite length is performed using the computational algorithm developed by projection method for the normal incident TEM-wave at terahertz ...

Group projection method in statistical systems [PDF]

open access: yes, 2003
We discuss an application of group theoretical methods to the formulation of the thermodynamics of systems constrained by the conservation laws described by a semi--simple compact Lie group.

Application of a Projection Method for Simulating Flow of a Shear-Thinning Fluid

open access: yesFluids, 2019
In this paper, a first-order projection method is used to solve the Navier−Stokes equations numerically for a time-dependent incompressible fluid inside a three-dimensional (3-D) lid-driven cavity. The flow structure in a cavity of aspect ratio

Geometric and projection effects in Kramers-Moyal analysis

open access: yes, 2009
Kramers-Moyal coefficients provide a simple and easily visualized method with which to analyze stochastic time series, particularly nonlinear ones. One mechanism that can affect the estimation of the coefficients is geometric projection effects. For some

Constructing Fewer Open Cells by GCD Computation in CAD Projection

open access: yes, 2014
A new projection operator based on cylindrical algebraic decomposition (CAD) is proposed. The new operator computes the intersection of projection factor sets produced by different CAD projection orders.

Surface Projection Method for Visualizing Volumetric Data [PDF]

open access: yes, 2006
The goal of this project was to explore, develop, and implement additional visualization methods for volumetric data within MindSeer. This paper discusses the implementation of one such visualization method, the surface projection method, and compares it

The Perfect Perspective: A Mathematical Analysis of Perspective Using Tools Available to Middle School Students [PDF]

open access: yes, 2003
This paper examines the basic properties of perspective drawings, the history of perspective drawings, and the basic mathematics of perspective. Using a side view and a top view of a three-dimensional projection, similar triangles can be used to find ...
