‎in this paper‎, ‎we propose two preconditioned aor iterative methods to solve systems of linear equations whose coefficient matrices are z-matrix‎. ‎these methods can be considered as improvements of two previously presented ones in the literature‎. ‎finally some numerical experiments are given to show the effectiveness of the proposed preconditioners‎.‎

this paper deals with scrutinizing the convergence properties of iterative methods to solve linear system of equations. recently, several types of the preconditioners have been applied for ameliorating the rate of convergence of the accelerated overrelaxation (aor) method. in this paper, we study the applicability of a general class of the preconditioned iterative methods under certain conditio...

a systematic way is presented for the construction of multi-step iterative method with frozen jacobian. the inclusion of an auxiliary function is discussed. the presented analysis shows that how to incorporate auxiliary function in a way that we can keep the order of convergence and computational cost of newton multi-step method. the auxiliary function provides us the way to overcome the singul...

Im Rahmen der Entwicklung einer neuen Steuerungsund Regelungstechnik für Feldspritzen wurde ein neues Bedienkonzept erdacht und umgesetzt. Das bestehende Spannungsfeld zwischen „intuitiv“ und „schön“ brachte im Laufe der Entwicklung veränderte Rahmenbedingungen und Anforderungen mit sich und erforderte eine iterative Überarbeitung des Konzepts.

in this work, a new iterative method is proposed for obtaining the approximate solution of a class of hammerstein type integral equations system. the main structure of this method is based on the richardson iterative method for solving an algebraic linear system of equations. some conditions for existence and unique solution of this type equations are imposed. convergence analysis and error bou...

services companies attempt to promote their delivered services to customers and achieve a stable competitive advantage. for achieving this goal, marketing and hr scholars jointly propose application of internal marketing (im) principles and instruments. although im is a 30 years old concept in management, but it's measurement and application method have faced with different structural and ...

A new auto-tuning approach for centralized MIMO PID controllers and unknown process models is presented. Classical multivariable PID controller tuning methods are combined with iterative feedback tuning (IFT) to develop an auto-tuning method with a bounded number of tuning parameters. The method is demonstrated and validated with a steam generator example. Very good simulation results are obtai...

This paper presents the results of RiMOM-IM in the Ontology Alignment Evaluation Initiative (OAEI) 2014.We only participated in IM@OAEI2014. We first describe the overall framework of our matching System (RiMOM-IM); then we detail the techniques used in the framework for instance matching. Last, we give a thorough analysis on our results and discuss some future work on RiMOM-IM. 1 Presentation ...

a constitutive model based on two–dimensional unstructured galerkin finite volume method (gfvm) is introduced and applied for analyzing nonlinear behavior of cracked concrete structures in equilibrium condition. the developed iterative solver treats concrete as an orthotropic nonlinear material and considers the softening and hardening behavior of concrete under compression and tension by using...
