A quasi-static analysis for a class of induced-current EIT systems using discrete coils
Koksal, A; Eyüboğlu, Behçet Murat; Demirbilek, M (Institute of Electrical and Electronics Engineers (IEEE), 2002-06-01)
A discrete coil EIT system is investigated for the general case of an eccentric circular inhomogeneity. The solution methodology of the forward problem of this system is explained. An optimization procedure using this forward problem solution is developed to rind optimum currents that maximize the distinguishability. For an eccentric inhomogeneity problem, it is shown that the coil currents can be optimized to focus the current density in a region of interest. Optimum coil currents under limited peak coil c...
A coupled numerical scheme of dual reciprocity BEM with DQM for the transient elastodynamic problems
Bozkaya, Canan (Wiley, 2008-11-12)
The two-dimensional transient elastodynamic problems are solved numerically by using the coupling of the dual reciprocity boundary element method (DRBEM) in spatial domain with the differential quadrature method (DQM) in time domain. The DRBEM with the fundamental solution of the Laplace equation transforms the domain integrals into the boundary integrals that contain the first- and the second-order time derivative terms. Thus, the application of DRBEM to elastodynamic problems results in a system of second...
A quasi inextensible element formulation for anisotropic continuum
Dal, Hüsnü (2016-06-10)
The contribution presents a novel finite element formulation for quasi-inextensible and quasi-incompressible finite hyperelastic behaviour of transeversely anisotropic materials and addresses its computational aspects. The formulation is presented in purely Eulerian setting and based on the additive decomposition of the free energy function into isotropic and anisotropic parts where the former is further decomposed into isochoric and volumetric parts. For the quasi-incompressible material response, the Q1P0...
A maximal covering location model in the presence of partial coverage
Karasakal, O; Karasakal, Esra (2004-08-01)
The maximal covering location problem (MCLP) addresses the issue of locating a predefined number of facilities in order to maximize the number of demand points that can be covered. In a classical sense, a demand point is assumed to be covered completely if located within the critical distance of the facility and not covered at all outside of the critical distance. Since the optimal solution to a MCLP is likely sensitive to the choice of the critical distance, determining a critical distance value when the c...
A modular regularized variational multiscale proper orthogonal decomposition for incompressible flows
Eroglu, Fatma G.; Kaya Merdan, Songül; Rebholz, Leo G. (Elsevier BV, 2017-10-01)
In this paper, we propose, analyze and test a post-processing implementation of a projection-based variational multiscale (VMS) method with proper orthogonal decomposition (POD) for the incompressible Navier-Stokes equations. The projection-based VMS stabilization is added as a separate post-processing step to the standard POD approximation, and since the stabilization step is completely decoupled, the method can easily be incorporated into existing codes, and stabilization parameters can be tuned independe...
