In this paper, we present a technique for the deposition of inks, toners, organic polymers, fuels, small solid particles, biological and chemical fluids, using a fluid ejector. The ejector design is based on a flextensional transducer that excites the axisymmetric resonant modes of a clamped circular plate. It is constructed by depositing a thin piezoelectric annular plate onto a thin, edge cla...

In this paper, buckling and free vibration analysis of a circular tapered nanoplate subjected to in-plane forces were studied. The linear variation of the plate thickness was considered in radial direction. Nonlocal elasticity theory was employed to capture size-dependent effects. The Raleigh-Ritz method and differential transform method were utilized to obtain the frequency equations for simpl...

In this paper, we study the problem of cutting a rectangular plate R of dimensions (L;W ) into as many circular pieces as possible. The circular pieces are of n di4erent types with radii ri; i = 1; : : : ; n. We solve the constrained circular problem, where di the maximum demand for piece type i is speci+ed, using two heuristics: a constructive procedure-based heuristic and a genetic algorithm-...

With the aim of achieving stable operation of circular saws, this study finds the solution for the optimization problem that involves choosing a set of tensioning parameters in a rotating circular saw that is subjected to both a local temperature distribution and the in-plane plastic strain over a double annular domain. The solution for the in-plane forces is obtained on the basis of plate bend...

The method of moments in the Hankel transform domain is applied to the determination of the fields scattered by a conducting circular plate buried in a lossy dispersive half-space when the plate is illuminated by a plane wave. The scattered fields obtained in the frequency domain are used to model the time-domain short-pulse scattering via the inverse fast Fourier transform. The authors show th...

High voltage electron microscopic tomography was used to determine the organization of the kinetochore plate and its attachment to the underlying chromosome. Six reconstructions were computed from thick sections of Colcemid-treated PtK1 cells and analyzed by a number of computer graphics methods including extensive thin slicing, three-dimensional masking, and volume rendering. When viewed en-fa...

A homogeneous, isotropic plate occupies the region 0 x1 ∞, |x2| a, |x3| h, where the semi-thickness h = h(x2). The ratio h(x2)/a is supposed to be everywhere sufficiently small so that the classical theory of bending of thin plates (of non-uniform thickness) applies. The short end of the plate at x1 = 0 is clamped while the long sides are free. This cantilever plate is now loaded at x1 = +∞ by ...
