In this article, recent investigations into the dynamic behavior of a pressure-sensor diaphragm under initial tension are presented. A comprehensive mechanics model based on a plate with in-plane tension is presented and linear analysis is carried out to examine the transition from plate behavior to membrane behavior. It is shown that, for certain tension parameter values, it is appropriate to ...

A class of model equations that describe the bi-directional propagation of small amplitude long waves on the surface of shallow water is derived from two-dimensional potential flow equations at various orders of approximation in two small parameters, namely the amplitude parameter a 1⁄4 a=h0 and wavelength parameter b 1⁄4 ðh0=lÞ2, where a and l are the actual amplitude and wavelength of the sur...

We explore the diversity of warped metric function in five dimensional gravity including a scalar field and a 3-brane. We point out that the form of the function is determined by a parameter introduced here. For a particular value of the parameter, the warped metric function is smooth without having a singularity, and we show that the bulk cosmological constant have a upper bound and must be po...

An effective biaxial tension and compression test method is proposed based on the shortcomings of current research for mechanical properties solid propellants under complex stress states. The equal proportion HTPB (Hydroxyl-terminated polybutadiene) NEPE (NitrateEster Plasticized Polyether) performed at different rates while room temperature, damage morphology tension–compression zone analyzed ...

The electromagnetic emission resulting from neutron star mergers have been shown to encode properties of the ejected material in their light curves. ejecta inferred kilonova has tension with those calculated based on gravitational wave signal and numerical relativity models. Motivated by this tension, we construct a broad set surrogate curve models derived for ejecta. four-parameter family two-...

The problem of scattering of capillary waves by a semi-infinite dock with a porous undulatory sea bed is attempted using perturbation technique. Two different eigen function expansions of the velocity potential function on the two sides of the surface discont inuity are constructed. An integral expression for first order reflection coefficient is arrived at involving the bottom shape function. ...

The solitary water wave problem is to find steady free surface waves which approach a constant level of depth in the far field. The main result is the existence of a family of exact solitarywaves of small amplitude for an arbitrary vorticity. Each solution has a supercritical parameter value and decays exponentially at infinity. The proof is based on a generalized implicit function theorem of t...

We give an analysis of a continuation algorithm for the numerical solution of the forcebased quasicontinuum equations. The approximate solution of the force-based quasicontinuum equations is computed by an iterative method using an energy-based quasicontinuum approximation as the preconditioner. The analysis presented in this paper is used to determine an efficient strategy for the parameter st...

The aim of this research is to design a controlling loop that eliminates the irregularities in yarn tension during the winding process. In order to achieve this, we employed a relative feedback industrial control system. The yarn tension sensor measures the tension. Its output is analyzed in the automatic controlling unit. This unit adjusts the tension level according to feedback signals, thus ...
