A second-order total variation diminishing (TVD) method with variable flux limiters is proposed to overcome the non-realizability issue, which has been one of major obstacles in applying conventional TVD schemes moment transport equations. In present method, a realizable set at cell face reconstructed by allowing flexible selection limiter values within region. Necessary conditions for scheme s...

We use Ehrenfeucht-type games to prove that Monadic Second Order logic admits labelled zero-one laws for random free trees, generating the complete almost sure theory. Our method will be to dissect random trees to get a picture of what almost all random free trees look like. We will use elementary (second moment) methods to obtain probability results. Abstract Key words: random labelled trees, ...

The safety of timber structure design based on the predicted Modulus of Rupture (MOR) of poplar lumber with nondestructive methods is presented in this paper. Dynamic Modulus of Elasticity (MOE) of poplar lumber was measured with three different nondestructive methods, and static MOE and MOR were obtained by a static bending test. The regression relationship between various MOE and MOR was eval...

By using the trigonometric uniform splines of order 3 with a real tension factor, a numericalmethod is developed for solving a linear second order boundary value problems (2VBP) withDirichlet, Neumann and Cauchy types boundary conditions. The moment at the knots isapproximated by central finite-difference method. The order of convergence of the methodand the theory is illustrated by solving tes...

In this paper, sensitivity and parametric analyses of impact intensity in crutch walking are investigated. The selected parameters of the crutch for these analyses are chosen as the mass, the second moment of inertia, and the location of the center of mass. The intensity of impact can be characterized by the pre-impact kinetic energy of the constrained motion space. Consequently, this part of t...

A new weighted geometric inequality is established by Klamkin’s polar moment of inertia inequality and the inversion transformation, some interesting applications of this result are given, and some conjectures which verified by computer are also mentioned

As the use of virtual teams has increased in organizations, there has been an increase in research focused on those settings. This study identifies factors associated with effectiveness and satisfaction at both the member and team level. Among other variables leadership characteristics and behaviors have been shown to influence virtual team outputs. However, new research in the leadership area,...
