The change from steel risers to composites comes with uncertainties that led large safety factors. One area of uncertainty is the predicted response and stresses derived commercial packages are based on formulations assume in-extensible riser. However, composite pipes exhibit a lower axial stiffness therefore velocity waves will corresponding in dynamic response. To determine effect this assump...

Recently, a novel reversible data hiding scheme is proposed for contrast enhancement by Wu (IEEE Signal Process Lett 22.1:81–85, 2015). Instead of pursuing the traditional high PSNR value, he designs the message embedding algorithm to enhance the contrast of the host image. In this paper, an extended scheme is proposed to not only adaptively enhance the contrast of the image, but also to keep t...

Abstract According to the surface equivalence theorem [1] , any enclosed with electric and magnetic current densities enforced on it can generate exactly same fields as original problem. The problem is how construct sources. In this paper, an efficient accurate unified approach equivalent density outermost boundary proposed solve transverse (TM) scattering problems by objects embedded in multil...

Booth and Cox proposed the E(s) criterion for constructing twolevel supersaturated designs. Nguyen [Technometrics 38 (1996) 69– 73] and Tang and Wu [Canad. J. Statist 25 (1997) 191–201] independently derived a lower bound for E(s). This lower bound can be achieved only when m is a multiple of N − 1, where m is the number of factors and N is the run size. We present a method that uses difference...

We consider the motion estimation problem in video coding. In our previous work [10], we proposed a new motion estimation method where motion estimation is formulated as an optimization problem and an adaptive system under the minimum error entropy criterion is used for motion estimation. In this paper, we develop an adaptive system under the criterion of maximum mutual information to address t...

Pressure vessels are essential industrial tools regarding storage of high-pressure fluids. Utilization pressure in ordinary environment impose serious dangers to human life case failure. Manufacturing material and working as per material’s strength necessary arguments for a vessel designer. In this study, five composite materials selected investigate the behavior under high pressure. FEA techni...
