the most important quality indicator of fruits is the flesh firmness which is well correlated to their young’s modulus. in this research variation of vibration characteristics (shape modes, natural frequency) of apple due to change of material characteristics (density, young's models, poisson ratio) and apple volume was investigated using finite element simulation. an image processing technique...

Fix integers b ≥ 2 and k ≥ 1. Define the sequence {zn} recursively by taking z0 to be any integer, and for n ≥ 1, take zn to be the least nonnegative residue of bzn−1 modulo (n + k). Since the modulus increases by 1 when stepping from one term to the next, such a definition will be called a running modulus recursion or rumor for short. While the terms of such sequences appear to bounce around i...

A new concept of stability, closely related to that of structural stability, is introduced and applied to the study of Cr endomorphisms with singularities. A map that is stable in this sense will be conjugated to each perturbation that is equivalent to it in a geometric sense. It will be shown that this kind of stability implies Axiom A, Omega-stability and that every critical point is wanderin...

Let φ be a modulus function, i.e., continuous strictly increasing function on [0,∞), such that φ(0) = 0, φ(1) = 1, and φ(x + y) ≤ φ(x) + φ(y) for all x, y in [0,∞). It is the object of this paper to characterize, for any Banach space X, extreme points, exposed points, and smooth points of the unit ball of the metric linear space `(X), the space of all sequences (xn), xn ∈ X, n = 1, 2, . . . , f...

Abstract The challenges behind this research were encountered while drilling into the Ilam, Mauddud, Gurpi, and Mishrif Formations, where severe instability-related issues observed across weaker formations above reservoir intervals. In paper, geomechanical parameters carried out to determine optimum mud weight windows safe deviation trajectories using parameters. We propose a workflow equivalen...

In this paper, we explain the mechanical properties of single-crystalline silicon with respect to deflectional and torsional motions. Young's modulus, Poisson’s ratio, and shear modulus are isotropic on silicon (111), whereas the variations on silicon (100) and (110) are quite significant. We newly derive formulae for bulk shear modulus of silicon (100), (110) and (111) and show that bulk shear...
