We address the problem of 6D pose estimation of a textureless and shiny object from single-view 2D images, for a bin-picking task. For a textureless object like a mechanical part, conventional visual feature matching usually fails due to the absence of rich texture features. Hierarchical template matching assumes that few templates can cover all object appearances. However, the appearance of a shiny object largely depends on its pose and illumination. Furthermore, in a bin-picking task, we must cope with partial occlusions, shadows, and inter-reflections. © 2012 IEEE.

A manganese-based solid solution with the composition of Li 1.95Mn 0.9Co 0.15O 3 was synthesized by a simplified coprecipitation method, followed by a combustion technique, and its electrochemical characteristics as a lithium-battery cathode were investigated. Rietveld refinement based on neutron diffraction data revealed that the material is assigned to an Li 2MnO 3-type structure model with a monoclinic cell due to the space group symmetry of C2m. In cycling of the LiLiLi 1.95Mn 0.9Co 0.15O 3 cell in the potential range of 2.0-4.8 V at current densities of 30 mAg -1, the discharge capacity characteristically increases from 46.3 to 196.5 mAhg -1 as the cycle increases from 1 to 11, and a discharge capacity of >175.5 mAhg -1 is obtained between the 23rd and 58th cycles with small capacity fading of 2.41. The results of cyclic voltammogram (CV) and X-ray photoelectron spectroscopy (XPS) measurements showed that the manganese redox reaction (Mn 3+Mn 4+) in the Li 1.95Mn 0.9Co 0.15O 3 system is progressively activated during the first ten-odd cycles, following continuous occurrence of the extraction of oxygen molecules from the electrode material over these charge processes. It could be assumed that such behaviors significantly influence the electrochemical characteristics of the Li 1.95Mn 0.9Co 0.15O 3 system. © 2012 The Electrochemical Society.

A numerical analysis has been performed for a developing turbulent flow in a rotating U-bend of strong curvature with rib-roughened walls using an anisotropic turbulent model. In this calculation, an algebraic Reynolds stress model is used to precisely predict Reynolds stresses, and a boundary-fitted coordinate system is introduced as a method of coordinate transformation to set the exact boundary conditions along the complicated shape of U-bend with rib-roughened walls. Calculated results for mean velocity and Reynolds stresses are compared to the experimental data in order to validate the proposed numerical method and the algebraic Reynolds stress model. Although agreement is certainly not perfect in all details, the present method can predict characteristic velocity profiles and reproduce the separated flow generated near the outer wall, which is located just downstream of the curved duct. The Reynolds stresses predicted by the proposed turbulent model agree well with the experimental data, except in regions of flow separation. © 2010 Taylor & Francis.

During the planning of Honda's new plant in Ogawa Japan, which is the new benchmark for developed countries power train plants, there was a project requirement established for a significant reduction in initial investment. In order to improve the competitive edge of module machines, which is the foundation of Honda's existing powertrain machining lines, Honda targeted a reduction in the number of module machines through concurrent machining of multiple workpieces, and minimization of transfer time. By developing exclusive jigs for cylinder heads and blocks, this project was able to meet the original project reduction requirements. In addition, Honda was able to shorten the loading and unloading times of a module machine by developing an exclusive transfer machine specifically for cylinder heads.

The simplified one-step hydrothermal synthesis, in which SiO 2 is directly reacted with aqueous NaOH in the presence or absence of tetrapropylammonium bromide (TPABr) and tetrabutylammonium bromide (TBABr) as the template compound, was investigated. The reaction in the absence of the template compounds leads to the production of pure magadiite, whereas pure Si-ZSM-5 is produced by the reaction in the presence of TPABr. On the other hand, crystalline magadiite/Si-ZSM-11 composites are synthesized by the reaction in the presence of TBABr. Furthermore, for the composites, the particle sizes of the magadiite and Si-ZSM-11 may be influenced by the TBABr concentrations. It was also found that the compositions of magadiite and Si-ZSM-11 in the composites can be controlled by regulating the NaOH concentrations. © 2010 The American Ceramic Society.
