The aim of this paper is to present a 3-D time-domain eddy-current formulation based on the discrete geometric approach (DGA) over unstructured and nonorthogonal hexahedral dual grids. The resulting differential algebraic system of equation, solved by means of a singly-diagonally implicit Runge–Kutta (SDIRK) variable step-size solver, leads to very accurate results at reduced computational cost...

This paper presents a novel interface element for the geometric and material nonlinear analysis of unreinforced brick-masonry structures. In the proposed modelling approach, the blocks are modelled using 3D continuum solid elements, while the mortar and brick-mortar interfaces are modelled by means of the 2D nonlinear interface element. This enables the representation of any 3D arrangement for ...

In this paper, we present a mesh-free, finite-volume-like scheme designed for numerically solving conservation laws. We first derive a conservative formulation for computing mesh-free first derivatives based on a set of unknown coefficients satisfying polynomial consistency and other conditions. This formulation leads to a generalization that allows flexible choices of flux schemes while remain...

This paper presents a time-domain formulation called Explicit Green’s approach (ExGA) linear method for the solution of the bioheat equation. Starting from the hyperbolic bioheat equation, which includes the parabolic one as a special case, the linear method is incorporated into the standard ExGA time marching scheme. The numerical Green’s function is firstly computed in the Laplace transform d...

A simple method is presented to reduce the number of scheduling parameters for gain-scheduled controller implementation. The method is based on careful reformulation of the dynamic representation using dimensionless parameters. Parameter re-scaling is necessary to transform from one unit system to another, and this work utilizes unit transformations carefully to act as an implicit method of gai...

©FSRH J Fam Plann Reprod Health Care 2009: 35(4) Summary Demography, health, human rights and morality have been important perspectives in the formulation of policies for the provision of contraceptive services. By addressing unmet need, implementation of the right to contraception leads to decreases in fertility and population growth, thereby promoting attainment of the Millennium Development ...

omega-3 fatty acids (fas) have been shown to prevent cardiovascular disease. the most commonly used omega-3 fatty acids like eicosapentaenoic acid (epa) and docosahexaenoic acid (dha) are highly vulnerable to oxidation and therefore, have short shelf life. recent advances in nanoliposomes provided a biocompatible system for stabilizing omega-3 fas. several methods could be implemented to prepar...

In this paper, we introduce, analyze and test first and second order stabilized discontinuous two-field mortar formulations for linearized elasticity problems, following the stabilization technique of Brezzi and Marini [BM00] introduced in the scalar elliptic case for a three-field formulation. All the fundamental assumptions arising in mortar formulations are proved for our discretization proc...

This talk contains a short review of some of the progresses made in the last three years in the calculations of electromagnetic cross sections of light nuclei up to A=7. Since many of them have been possible thanks to the use of the Lorentz Integral Transform (LIT) method, both for inclusive and exclusive reactions, I will first make a few remarks on the method, stressing its essential points a...
