The emphasis of this review is to discuss three peculiar phenomena bubbles rising in viscoelastic fluids, namely, the formation a cusp, negative wake, and velocity jump discontinuity, highlight possible future directions subject. mechanism influencing factors these have been discussed detail review. evolution bubble shape mainly related viscoelasticity fluid. However, mechanisms two-dimensional...

deterioration of soft magnetic properties of amorphous ribbons happens when oxygen atoms diffuse in matrix during heat treatment. in this research, surface oxidation of co67fe4cr7si8b14 amorphous ribbons prepared by planar flow melt spinning (pfms) process during crystallization was investigated. in the first step, thermal stability of the ribbons was studied by differential thermal analysis (d...

The primary somatosensory cortex contains a topographic map of the body surface, with two notable discontinuities — the representation of the face is next to that of the hands, and that of the feet is next to the genitals. Farah (1998) has suggested that these discontinuities are due to the mechanisms of self-organisation which underlie cortical map development. The typical position of the foet...

A crack initiation and propagation algorithm driven by non-local ductile damage is proposed in a three-dimensional finite strain framework. The evolution of plastic strain and stress triaxiality govern a non-local ductile damage field via constitutive equations. When the damage reaches a critical threshold, a discontinuity in the form of a crack surface is inserted into the three-dimensional co...

Introduction: The load-dependent collageneous fiber organization in the joint cartilage determines the biomechanical properties of this tissue. It has been shown that the deformation mechanisms of the collagen network under compressive load depend on the morphological and structural intactness of the cartilage [1, 2]. Thus, the analysis of load-reactions of joint cartilage could be a successful...

The primary somatosensory cortex contains a topographic map of the body surface, with two notable discontinuities—the representation of the face is next to that of the hands, and that of the feet is next to the genitals. Farah [Why does the somatosensory homunculus have hands next to face and feet next to genitals? a hypothesis. Neural Computation 10(8) (1998) 1983–1985] has suggested that thes...

Surrogate models for computational simulations are input-output approximations that allow computationally intensive analyses, such as uncertainty propagation and inference, to be performed efficiently. When a simulation output does not depend smoothly on its inputs, the error and convergence rate of many approximation methods deteriorate substantially. This paper details a method for efficientl...

Though the importance of curvature continuity on compressor blade performances has been realized, there are two major questions that need to be solved, i.e., the respective effects of curvature continuity at the leading-edge blend point and the main surface, and the contradiction between the traditional theory and experimental observations in the effect of those novel leading-edge shapes with s...

a considerable amount of energy is released in the form of shock wave from explosive charge detonation. shock wave energy is responsible for the creation of crushing and fracture zone around the blast hole. the rest of the shock wave energy is transferred to rock mass as ground vibration. ground vibration is conveyed to the adjacent structures by body and surface waves. geological structures li...
