Growth conditions on powers of Hermitian elements

Mathematical Proceedings of the Cambridge Philosophical Society, 1982
Roe (7) has recently given a striking characterization of the sine function as essentially the only function defined on the real line which has all its derivatives and successive ‘integrals’ bounded by a uniform bound, and this result has since been generalized by Burkill (5).

On the Maximum Angle Condition for Linear Tetrahedral Elements

SIAM Journal on Numerical Analysis, 1992
Summary: Synge's maximum angle condition for triangular elements is generalized to tetrahedral elements. For the generalized condition, it is proved that tetrahedra may degenerate in a certain way and the error of the standard linear interpolation remains \(O(h)\) in the \(W^ 1_ p(\Omega)\)-norm for sufficiently smooth functions and \(p\in[1,\infty]\).

Tribology Extenics Condition Evaluation Based on Matter Element Theory

2009 WASE International Conference on Information Engineering, 2009
The tribo-system has non-linear and randomfeatures; it means that the tribo-system output parameters,such as friction coefficient, friction temperature, friction ratioetc. have steady or non-steady random features. Adoptingmatter element model to describe the tribo-system conditioncan integrate different types information into a model andrealize the ...

On boundary conditions in the element-free Galerkin method

Computational Mechanics, 1997
The problem of accuracte imposition of essential boundary conditions in the element free Galerkin method is discussed. Using this method some difficulties often occur, because the moving least squares interpolants used in this method lack the delta function property of the usual finite element or boundary element method shape functions.

Reflectarray element analysis based on generalized sheet transition conditions

2017 11th European Conference on Antennas and Propagation (EUCAP), 2017
The surface electric and magnetic susceptibilities and the surface impedance of an array composed of periodic scatterers are derived based on generalized sheet transition conditions. Using these characteristic parameters, the reflection coefficient of a reflectarray element can be readily computed for arbitrary incident angles, polarizations, and ...

On conditions of existence of sums of functions of conditioned random elements

Journal of Mathematical Sciences, 2005
Let \((\Omega,\mathcal S,\mathbb P)\) and \((\mathcal F,\mathcal B)\) be probability and measurable spaces, respectively. Any \((\mathcal B,\mathcal S)\)-measurable mapping of a set \(\Omega\) into a set \(\mathcal F\) is called a random element. Let \(w_1,w_2,\dots,w_N\) be random elements given on a probability space \((\Omega_1,{\mathcal S}_1 ...

Finite element GPR numerical simulations based on mixed boundary conditions

2012 14th International Conference on Ground Penetrating Radar (GPR), 2012
With the consideration of different theoretical mechanisms for the transmitting and Sarma boundary conditions, a mixed boundary condition is proposed that combines both boundary conditions. This enables the remaining energy of a GPR wave to be transmitted through the boundary after it is attenuated and absorbed as specified by the Sarma boundary ...

Effect of Boundary Conditions on Finite Element Submodeling

When a built-up structure such as a turbine or compressor is modeled with finite elements, a submodeling procedure can be used to assess critical features such as holes, fillets, or contact interfaces. To employ the method, one builds and solves a coarse-mesh finite element model of the whole structure.
