A systematic procedure is developed for analysing the Jacobians of planar finite elements. Conditions are derived for the Jacobians to be linear or multilinear in the two isoparametric coordinates. For the case of the 6-noded triangle a complete geom

An extension to a two-dimensional compressible dynamic viscoelastic cylinder problem using the finite element method in the Laplace domain coupled with fast Fourier transform is performed. The governing viscoelastic equations of motion are transforme

Finite element methods can be used for determining the flow in a straight channel under a variety of wall conductivity conditions when a uniform magnetic field is imposed perpendicular to the flow direction. At high Hartmann numbers oscillatory solut

It is well known that the condition under which a quadratic in two variables reduces to a product of two linear factors is that the determinant of the associated quadratic form should be zero. This result is generalized to the case of a polynomial of

Isoparametric elements are only valid if the Jacobian determinant of the transformation between a given element and a master element does not change sign within or on the element boundary. Some algorithms are known which analyse Jacobians for various

Modulation of immunologic effector cells by exogenous photoactive substances has been advanced as an underlying mechanism for the efficacy of various photochemotherapeutic regimens. It is also possible that endogenous photosensitizers, such as protop
