Block method for problems on L-shaped domains

Dosiyev, A.A; Mazhar, Zeka; Buranay, S.C (Elsevier, 2010)

An extremely accurate, exponentially convergent solution is presented for both symmetric and non-symmetric Laplacian problems on L-shaped domains by using one-block version of the block method (BM). A simple and highly ...
Boundary Value Problems Arising in Kalman Filtering

Bashirov, Agamirza; Mazhar, Zeka; Ertürk, Sinem (Hindawi Publishing Corporation, 2009-01-01)
Boundary Value Problems Arising in Kalman Filtering

Bashirov, Agamirza; Mazhar, Zeka; Ertürk, Sinem (Springer International Publishing, 2008)

The classic Kalman filtering equations for independent and correlated white noises are ordinary differential equations (deterministic or stochastic) with the respective initial conditions. Changing the noise processes by ...
Delay structure of wideband noises with application to filtering problems

Bashirov, Agamirza; Mazhar, Zeka; Etikan, Hüseyin; Ertürk, Sinem (Wiley Online Library, 2013)

Filtering of random processes is one of the central subjects in the theory of random processes. Especially, Kalman filtering, originating from the famous works of Kalman and Bucy [1, 2], is one of the powerful methods of ...
An Enhancement To The Block Implicit Procedure For The Treatment Of The Velocity-Pressure Coupling Problem In Incompressıble Fluid Flow

Mazhar, Zeka (Taylor & Francis, 2002)

The performance of two new non-segregated, block implicit procedures; BIP and BIPEN are compared with the well known SIMPLER procedure, applied to benchmark problems of various sizes. It is demonstrated that BIP provides ...
A Novel Fully Implicit Block Coupled Solution Strategy For The Ultimate Treatment of The Velocity–Pressure Coupling Problem in İncompressible Fluid Flow

Mazhar, Zeka (Taylor & Francis (Routledge), 2016-01-21)

Two new extremely robust, fully implicit coupled solution procedures (FICS-1 and FICS-2) are presented for the ultimate solution of the notorious velocity–pressure coupling problem arising in incompressible fluid flow ...
On asymptotical behavior of solution of Riccati equation arising in linear filtering with shifted noises

Bashirov, Agamirza E.; Mazhar, Zeka (Springer, 2007)

In this paper we consider a linear signal system together with the two linear observation systems. The observation systems differ from each other by the noise processes. The noise of one of them is a constant shift in time ...
On asymptotical behavior of solution of Riccati equation arising in linear filtering with shifted noises

Mazhar, Zeka; Bashirov, Agamirza E. (Springer Netherlands, 2007)

In this paper we consider a linear signal system together with the two linear observation systems. The observation systems differ from each other by the noise processes. The noise of one of them is a constant shift in time ...
On the preconditioning conjugate gradient method for the solution of 9-point elliptic difference equations

Mazhar, Zeka; Daoud, D.S; Subaşı, Deniz (Elsevier B.V, 1994)

The Preconditioned Conjugate Gradient (PCG) method is implemented to solve the system with 9 diagonal entries generated from a 9-point finite difference approximation of the self-adjoint elliptic partial differential ...
A PROCEDURE FOR THE TREATMENT OF THE VELOCITY-PRESSURE COUPLING PROBLEM IN INCOMPRESSIBLE FLUID FLOW

Mazhar, Zeka (Taylor & Francis (Routledge), 2001)

A new block implicit procedure ( BID) is introduced which utilizes a simple incomplete decomposition of the matrix resulting from the discretization of the momentum and mass conservation equations for incompressible uid ...
