Mechanical properties in tension of mechanically attrited nanocrystalline iron by the use of the miniaturized disk bend test

The mechanical properties of warm compacted nanocrystalline (nc) iron powder compacts of near theoretical density in the grain size range between 8 and 33 nm were investigated. The elastic and plastic behavior were characterized by miniaturized disk bend tests and hardness measurements. Light and scanning electron microscopy (SEM) were used to document the deformation and fracture morphologies. The Young's modulus of the nc Fe was essentially the same as that of coarse grained Fe. All samples failed in a macroscopically brittle manner. Local plasticity in shear bands was observed in the samples with the larger grain sizes (>20 nm). An increasing failure stress with increasing grain size is probably due to a processing effect on the flaw controlled failure of the samples. The results are discussed in the context of the deformation and fracture behavior of micrometer grain size metals and alloys.     

基于数学形态学和BP神经网络的足趾形状识别方法

根据足趾二值图像形状特征,提出基于数学形态学消散度技术的足趾形状特征提取及BP神经网络聚类的足趾形状识别方法。该法依据数学形态学理论提取物体形心,仅受较少边界凹点影响,对噪声不敏感,比几何中心稳定。提取边界上距形心距离稳定并能区分不同形状的特征点及相互关系,生成特征向量。此向量在二维连续空间中,具有平移、旋转、尺度不变特征;在二维离散应用环境中,由平移、旋转、尺度变化造成误差小,稳定性强。用训练成功的BP神经网络,对不同质量足趾图像识别,均能达到较高识别率。大量实验表明,该法是满足识别精度要求、识别率高于其它方法的一种行之有效的足趾形状识别方法。

An architecture for processing graph-grammar applications

We propose a six-layer architecture for processing graph-grammar applications. The layers and the transformations between them are formally described and concepts for their implementation are given. Especially we introduce the syntax and semantics of a graph-grammar implementation language. Graph-grammar productions will be translated into programs of this language to have a basis for their implementation into programs written in commonly available programming languages.
