In this paper, we propose a wide-viewing-angle three-dimensional integral imaging using a curved screen and a curved lens array. Elemental images are projected to the curved screen. Incorporation of the curved screen and the curved lens array instead of a conventional flat display panel and a flat lens array expands the viewing angle remarkably. In addition adopting barriers between a curved le...

Abstract This study carried out finite element dynamic analyses of carbon nanotubes/fiber/polymer composites (CNTFPC) with various geometries. In the first application, effects CNTs on nonlinear transient responses doubly curved shells for cutout sizes and curvatures are studied. The numerical results obtained in good agreement those reported by other investigators. For practical focus this is ...

A method is presented for determining the free vibration frequencies of doubly curved, isotropic shallow shells under general edge conditions and used to obtain accurate natural wide range geometric parameters. Based on shell theory applicable thin thickness shells, a Ritz extended derive frequency equation wherein displacement functions are modified accommodate arbitrary sets both in-plane out...

We present preliminary results from Fermilab E791 on D 0 ? D 0 mixing and doubly Cabibbo-suppressed decays (DCSD) of the D 0 and D + mesons. The time dependence of the wrong-sign signal (D 0 ! K + ?) is used to establish separate limits on DCSD and mixing. From one third of our data we obtained r mix < 0:47%, r DCSD < 2:7% at the 90% conndence level.
