In this note we continue the development of optimization problems for IIUs. Here we optimize the impedance for ifilnitely long TEM horns (an approximation for finite-length horns) and TEM horns with lenses, or lens lRAs. These calculations are analogous to those carried out for reflector EL% in Part I of this paper [1]. We consider both TEM horns whose plates are flat, and whose plates are coni...

Based on the concept of discontinuity displacement, an analytical solution for cracked thin plates has been derived in which displacements and stresses in a solid can be expressed by the linear distributed discontinuity displacements on the whole boundary. By way of the potential variational principle and the analytical solution newly developed, a boundary element model for 2D multiple crack pr...

The possibility of quantitating insect ecdysones in situ on thin-layer chromatographic plates was examined. Two approaches were evaluated: 1) the induction of ecdysone fluorescence by sulfuric acid treatments and 2) the fluorescence-quenching of fluorescent thin-layer chromatographic plates by ecdysones. The fluorescence-quenching method was found to be most suitable and had a linear response r...

The interplay between multiscale homogenization and dimension reduction for nonlinear elastic thin plates is analyzed in the case in which the scaling of the energy corresponds to Kirchhoff’s nonlinear bending theory for plates. Different limit models are deduced depending on the relative ratio between the thickness parameter h and the two homogenization scales ε and ε.

The Direct Simulation Monte Carlo (DSMC) method was used to study the evaporation / condensation of iodine evaporating between parallel circular plates. The numerical 1D and 2D solutions are compared to the experimental result obtained by Mager et al.

Sporocysts of Isospora endocallimici, a parasite of marmosets, were exposed to minimal essentials medium (MEM) or a trypsin-bile salt solution (TBS) and then fixed and prepared for transmission electron microscopy. Excystation occurred in TBS but not MEM. The sporocyst wall has 2 layers, a thin outer layer (15 to 110 nm thick) and a thick inner layer (65 to 180 nm thick), which is composed of 4...

Abstract   In this study, generalized differential quadrature analysis of elastic/plastic buckling of skew thin plates is presented. The governing equations are derived for the first time based on the incremental and deformation theories of plasticity and classical plate theory (CPT). The elastic/plastic behavior of plates is described by the Ramberg-Osgood model. The ranges of plate geometries...

Origami structures enrich the field of mechanical metamaterials with the ability to convert morphologically and systematically between two-dimensional (2D) thin sheets and three-dimensional (3D) spatial structures. In this study, an in-plane design method is proposed to approximate curved surfaces of interest with generalized Miura-ori units. Using this method, two combination types of crease l...
