The most prominent feature of sheet material forming process is an elastic recovery phenomenon during unloading which leads to springback and side wall curl. Therefore evaluation of springback and side wall curl is mandatory for production of precise products. In this paper, the effects of some parameters such as friction coefficient, sheet thickness, yield strength of sheet and blank-holder fo...

In this study, a method based on using image processing and artificial neural network is introduced to determine pelt color and curl size of newborn lambs in Zandi sheep. The data was collected from 300 newborn lambs reared in the Zandi sheep breeding centre of Khojir, Tehran. Primarily, curl size and pelt color of new born lambs was recorded by experienced appraisers, and at the same time, sev...

Abstract A Lagrange finite element method is proposed for Maxwell’s equations in Lipschitz domains. The suitable the approximation of singular solutions lying outside $(H^1(\varOmega ))^3$, with nonhomogeneous boundary data tangential trace space $H({\mathbf{curl}}; \varOmega )$ and a right-hand-side source term $(H_0({\mathbf{curl}}; ))^{\prime}$ (the dual $H_0({\mathbf{curl}}; ))$. Numerical ...

The Web has transformed how we access information and applications, but Web application platforms have lagged behind the vision: Highly usable Web applications are too hard to build using established Web technology platforms. Web content needs to span the spectrum from simple formatted text, through graphics, animations, and scripting, to enterprise-scale applications that use client-side compu...

We obtain a necessary and sufficient condition for the relation ‖∇u‖2 = ‖curl u‖2 + ‖div between main operations of field theory (gradient, curl, divergence) on boundary domain. As an application, we consider analog classical Neumann problem in find right-hand side equation weak solution to be generalized solution.

In recent years leaf curl disease of cotton has become a major limiting factor in the production of cotton, which is an important fiber cash crop. In the last two decades or more, leaf curl disease in cotton took on epidemic proportions in Pakistan. In the early 1990’s cotton leaf curl disease (CLCuD) appeared in the bordering parts of India in the states of Rajasthan and Punjab and spread to e...

Intestinal diverticulosis refers to sac like protrusions at the points of intestinal wall weakness where the blood vessels are penetrating. They are mostly asymptomatic but they can present in the form of pain, perforation, hemorrhage or combination of these. Intestinal vessels responsible for diverticulosis, curl over the wall of diverticula, and are separated from the lumen only with the muco...

For plant viruses to systemically infect a host requires the active participation of viral-encoded movement proteins. It has been suggested that BL1 and BR1, the two movement proteins encoded by the bipartite geminivirus squash leaf curl virus (SqLCV), act cooperatively to facilitate movement of the viral single-stranded DNA genome from its site of replication in the nucleus to the cell periphe...
