We present a new algorithm, called "Sewing Faces". From 3D images deened by a block of voxels, this algorithm based on a contour following reconstructs bounding surfaces of 6-connected objects. A bounding surface is a set of faces shared by two voxels : one belonging to the object, the other one belonging to its complement. The topological model used to represent these surfaces consists in a se...

Gravitational collapse of cylindrical anisotropic fluid has been considered in analogy with the work of Misner and Sharp. Using Darmois matching conditions, the interior cylindrical dissipative fluid (in the form of shear viscosity and heat flux )is matched to an exterior vacuum Einstein–Rosen space-time. It is found that on the bounding 3-surface the radial pressure of the anisotropic perfect ...

A new elastic-viscoplastic (EVP) constitutive model is proposed for the analysis of time-dependent behavior of clay. The proposed model is based on the bounding surface plasticity and the concept of viscoplastic consistency framework to establish continuous transition from plasticity to rate dependent viscoplasticity. Unlike the overstress based models, this model will meet the consistency cond...

this paper studies the effect of flexible linear torso on the dynamics of passive quadruped bounding. a reduced-order passive and conservative model with linear flexible torso and springy legs is introduced. the model features extensive spine deformation during high-speed bounding, resembling those observed in a cheetah. fixed points corresponding to cyclic bounding motions are found and calcul...

The Kirchhoff-Plateau problem concerns the equilibrium shapes of a system in which a flexible filament in the form of a closed loop is spanned by a liquid film, with the filament being modeled as a Kirchhoff rod and the action of the spanning surface being solely due to surface tension. We establish the existence of an equilibrium shape that minimizes the total energy of the system under the ph...

this paper presents evidence on mesozoic inversion of basin bounding faults within the taleqan-gajereh-lar paleograben (tglp) in central alborz range. for this purpose, well documented stratigraphy data across the tglp together with the new acquired structural data on the geometry and kinematics of the paleograben basin bounding faults are utilized. the tglp has evolved through the early and mi...

We present an algorithm which is capable of globally solving a well-constrained transcendental system over some sub-domainD ⊂ R, isolating all roots. Such a system consists of n unknowns and n regular functions, where each may contain non-algebraic (transcendental) functions like sin, exp or log. Every equation is considered as a hyper-surface in R and thus a bounding cone of its normal (gradie...
