artificial neural networks (anns) are computer techniques that attempt to simulate the functionality and decision-making processes of the human brain. in the past few decades, artificial neural networks (anns) have been extensively used in a wide range of engineering applications. there are only a few applications in liquid membrane process. the objective of this research was to develop artific...

We perform a linear stability analysis of an elementary 1D model obtained from a Level Set formulation of the coupling between an immersed elastic interface and the surrounding fluid. Despite the striking simplicity of the studied model, relevant instability regimes are obtained, unifying results obtained in previous studies [5, 17]. We also present numerical tests on the full model which furth...

Continuous glucose monitoring (CGM) by suitable portable sensors plays a central role in the treatment of diabetes, a disease currently affecting more than 350 million people worldwide. Noninvasive CGM (NI-CGM), in particular, is appealing for reasons related to patient comfort (no needles are used) but challenging. NI-CGM prototypes exploiting multisensor approaches have been recently proposed...

An improved variation of a technique recently published by Brailsford et al.6 to determine the elastic properties of erythrocytes is presented. The method involves the use of Nuclepore filters (pore diameter, 0.7 im or 1.0 tm and pore density, 2 x 1 0 pores/sq cm), erythrocytes being partially aspirated by the action of positive hydrostatic pressure. The dimensions of the aspirated “tongue,” as...

Abstract This paper presents a beam theory for analyzing the static response of slightly curved three-layer beams with interlayer slip. Since are supposed to be immovably supported, membrane stresses develop even at moderately large deflections and becomes geometrically nonlinear. The is based on layerwise application Euler–Bernoulli linear elastic constitutive law interlaminar displacements. I...

Cephalopods use large-scale structural deformation to propel themselves underwater, changing their internal volume by 20–50%. In this work, the hydroelastic response of a swimmer comprised fluid-filled elastic-membrane is studied via an analytic formulation two coupled non-linear dynamic equations. This model self-propelled soft-body dynamics incorporates interplay external and added-mass varia...

A study of the histogenesis of elastic tissue in the embryonic ductus arteriosus of Sus scrofa is in accord with the theory that elastic fibrils are directly differentiated in the outlying portion of the protoplasm of the early connective tissue cell. In the occlusion of the postfetal ductus arteriosus of Sus scrofa there is early a hypertrophy of the internal elastic membrane. Subsequently the...

The elastic properties of the human red blood cell membrane have been measured as functions of temperature. The area compressibility modulus and the elastic shear modulus, which together characterize the surface elastic behavior of the membrane, have been measured over the temperature range of 2-50 degrees C with micropipette aspiration of flaccid and osmotically swollen red cells. In addition,...

An elastic membrane stretched between two walls takes a shape defined by its length and the volume of fluid it encloses. Many biological structures, such as cells, mitochondria and coiled DNA, have fine internal structure in which a membrane (or elastic member) is geometrically 'confined' by another object. Here, the two-dimensional shape of an elastic membrane in a 'confining' box is studied b...
