There are two cases of the exterior problems of the Helmholtz equation. If λ > 0 the bilinear form is coercive, and if λ < 0 it is the scattering problem.We gi
We give definitions of real piecewise algebraic variety and its dimension. By using the techniques of real radical ideal, P-radical ideal, affine Hilbert polyno
Laser powder bed fusion (LPBF), like many other additive manufacturing techniques, offers flexibility in design expected to become a disruption to the manufactu
Using double set parameter method, a 12-parameter trapezoidal plate bending element is presented. The first set of degrees of freedom, which make the element co
