Conservative Front Tracking in Higher Space Dimensions
We propose a fully conservative Front Tracking algorithm in two space dimension. The algorithm rst uses the point shifted algorithm 12] on two adjacent time levels and then constructs space time hexahedra as computational units. We develope and prove a successful geometric construction under certain interface requirement. This algorithm has a rst order local truncation error for cells near the ...
متن کاملComposite quarks and leptons in higher space-time dimensions
A new approach towards the composite structure of quarks and leptons in the context of the higher dimensional unified theories is proposed. Owing to the certain strong dynamics, much like an ordinary QCD, every possible vectorlike set of composites appears in higher dimensional bulk space-time, however, through a proper Sherk-Schwarz compactification only chiral multiplets of composite quarks a...
متن کاملZero Biasing in One and Higher Dimensions, and Applications
Given any mean zero, finite variance σ2 random variable W , there exists a unique distribution on a variable W ∗ such that EWf(W ) = σ2Ef ′(W ∗) for all absolutely continuous functions f for which these expectations exist. This distributional ‘zero bias’ transformation of W to W ∗, of which the normal is the unique fixed point, was introduced in [9] to obtain bounds in normal approximations. Af...
متن کامل: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
15 صفحه اولThe Thin Viscous Flow Equation in Higher Space Dimensions
We prove local integral (entropy) estimates for nonnegative solutions of the fourth order degenerate parabolic equation u t + div(u n ru) = 0 in space dimensions two and three. These estimates enable us to show that solutions have nite speed of propagation if n 2 (1 8 ; 2) and that the support cannot shrink if the growth exponent n is larger than 3=2. In addition, we prove decay estimates for s...
