The printing equipments of Information Technology (IT) have grown rapidly and diversely coping with heterogeneous requirements today, especially for those printers. but dot-matrix printers break those rules. Although laser-printers or inkjet printers ,etc. have become very popular and useful for printing issues. But the dot-printers are still not faded out from IT-users, especially for those commercial enterprises. The central characteristics are the carbon-papers that used for some formal and financial information printed on them to offer the customers, suppliers, users, official staffs to sign their signatures by their handwriting. Those carbon-papers printing with signature written one time can be divided over two copies with the same handwriting repeated automatically. Today, the laser-printers or inkjet-printers with high-technology can make printing colorful, high-quality, high-speed and multi-functions, but they are impossible to do the carbon-papers printing like the dot-matrix printers. The previous researches proposed in "Template Printing Script Language (TPSL)" and " Virtual Printing Server (VPS)" have solved the Template Printing (TP) problems in heterogeneous environments including heterogeneous OS version, hardware, different brand printers or different model printers. But there are some problems for mobile environment unsolved with template-printing problems. More and more users like to use mobile devices like mobile-phone or tablets PC equipped i-OS or Android-OS installed everywhere. Mobile applications working on the platform of i-OS or Android still meet the template printing requirements. If mobile-users sign their signatures on the template-printing papers like PC-users, the touch screen and writable characteristic of mobile devices become useless and unnecessary. The convenience, simplicity and mobility for mobile devices must enrich new functions based on the mentioned issues above. The study proposes an architecture to extend the Visual Printer Server (VPS) to facilitate the mobile-users to preview the results of the template-printing on mobile environment to confirm the correct information and to write signatures by using theirs mobile devices. Finally the Instant-Preview Virtual Printing Server (IPVPS) merges the mobile-users' signatures into the formal printing results and sends them back to the mobile-users.
method is valid for all of the R/H values and gives predictions that are in agreement with those of Ref. 3.As a second example, cross-ply, orthotropically laminated cylindrical shells are modeled. The thickness of every layer is the same: h k = H/NL. The laminating sequence, which starts with the first (inner) layer, is 90/0/90..., where 90 deg means that the fibers are aligned with the 0 direction and 0 deg the ;c direction. The shell is subject to the patch load shown in Fig. 1. The width and subtended angle of the load are taken as L p = L/4 and 9 P = n/8.The proposed three-dimensional elasticity theory is compared with the CLT and the HSDT. Figure 2 shows the distributions of the stresses a x and a$ of a two-layered shell along the radial direction. Because the shell is thin (R/H = 10), the predictions by these theories have small deviations. However, when the shell is relatively thick, say R/H = 5, CLT and HSDT lead to large errors, as shown in Figs. 3 and 4 where the stress distributions of a two-layered shell and a five-layered shell are plotted. Apparently, in this case, three-dimensional elasticity theories have to be utilized. Concluding RemarksThe proposed method is highly accurate in predicting the threedimensional stresses and displacements of composite shells with arbitrary thickness. One advantage of the method is that various loads and lamina properties are systematically treated by the explicit and compact matrix form of the spatial state-space formulation, which is convenient for computing coding.For an orthotropic cylindrical shell, the transverse deformation and three-dimensional deformation effects are significant even if the shell is moderately thick. With L/R = 1, the classic laminated theory can only be used with reasonable accuracy for R/H > 20 and higher order shear deformation theory is reliable for R/H > 10. It is seen that three-dimensional elastic deformation must be taken into consideration even for moderately thick shells, not to mention very thick shells. The proposed method is valid for both thin and thick shells with arbitrary R/H values.Although this work has focused on SS shells, the proposed method is readily extended to more general boundary conditions. Also, the method can be applied to dynamic problems of laminated shells when combined with the distributed transfer function method. IntroductionA DVANCED composite materials have been used in the aerospace industry because of high strength and low weight. Resin transfer molding (RTM) is believed to be one of the candidates for fabricating advanced composites with lower cost. 1 * 2 Application of composite materials to aircraft fuselage or wing structures offers potentially significant weight reduction relative to the metallic structures. Stiffened panels are the basic unit of these structures. Traditionally, the stiffened panels have been fabricated by the techniques of adhesive bonding or cocuring of the skin and stiffener components made of prepreg laminates. To reduce the cost, the RTM process could be used to fabricate c...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
