Uniform radial expansion/contraction of carbon nanotubes
Carbon nanotubes have very high potential for applications in nanoelectromechanical devices, nano-optomechanical systems and nanocomposites. However, their full exploitation depends upon knowledge of their mechanical, electrical and thermal properties. Several analytical, experimental, molecular mechanics (MM) and molecular dynamics simulations have been performed to study their deformations un...
متن کاملNear convexity, metric convexity, and convexity
It is shown that a subset of a uniformly convex normed space is nearly convex if and only if its closure is convex. Also, a normed space satisfying a mild completeness property is strictly convex if and only if every metrically convex subset is convex. 1 Classical and constructive mathematics The arguments in this paper conform to constructive mathematics in the sense of Errett Bishop. This mea...
متن کاملConvexity of Hypersurfaces in Spherical Spaces
A spherical set is called convex if for every pair of its points there is at least one minimal geodesic segment that joins these points and lies in the set. We prove that for n ≥ 3 a complete locally-convex (topological) immersion of a connected (n−1)-manifold into the n-sphere is a surjection onto the boundary of a convex set.
متن کاملConvexity and Solvability for Compactly Supported Radial Basis Functions with Different Shapes
It is known that interpolation with radial basis functions of the same shape can guarantee a non-singular interpolation matrix, whereas little is known when one uses various shapes. In this paper, we prove that a class of compactly supported radial basis functions are convex on a certain region; based on this local convexity and ready local geometrical property of the interpolation points, we c...

3 A variational approximation scheme for radial elasticity that preserves the positivity of Jacobians 53 3. Bibliography 101 ii Chapter 1 Introduction In continuum physics, material bodies are modeled as continuous media whose motion and equilibrium is governed by balance laws and constitutive relations. The list of balance laws identifies the theory, for instance, mechanics, thermomechan-ics, ...
