基于LED与肌肉模型的特定人脸建模与动画

特定三维人脸的建模与动画是计算机图形学中一个非常令人感兴趣的领域.本文提出了一种新的从两幅正交照片建立特定人脸的模型以及动画方法,首先以主动轮廓跟踪技术snake自动获取人脸特征点的准确位置,然后以文中的局部弹性变形(local elastic deformation)方法进行通用人脸模型到特定人脸的定制,并辅以采用图像镶嵌技术生成的大分辨率纹理图像施行纹理绘制,该方法以特征点的位移和非特征点与特征点的相对位置为基础计算局部人脸面部的变形,同时还能够实现人脸剧烈的面部变化和动作,与肌肉模型相结合,可很好地实时完成人脸的动画,具有快速高效的特点.最后,给出了所得到的实验结果.

太钢3号卷取机TDC控制系统开发与应用

太钢热连轧厂3号卷取机改造前所采用的美国西屋公司WDPF控制系统已不能满足目前生产和质量的要求，进而应用西门子公司的TDC控制系统对其进行了改造。该项目的设计、编程、调试由太钢自行完成，改造中采用了带钢头部张力优化控制、夹送辊张力控制、卷取机平滑曲线减张控制、卸卷小车横移极限升降极限模拟控制等多项新技术。其改造后产品产量、综合成卷率和卷形良好率均明显提高。     

Numerical Simulation of Independent Advance of Ore Breaking in the Non-pillar Sublevel Caving Method

The mechanism of stress generation and propagation by detonation loading in five separate independent advance of ore breaking patterns is discussed in the paper. An elastic numerical model was developed using AN- SYS/LS-DYNA 3D Nonlinear Dynamic Finite Element Software. In this package ANSYS is the preprocessor and LS-DYNA is the postprocessor. Numerical models in the paper to actual were l：10 and the element mesh was dissected in scanning mode utilizing the symmetry characteristics of the numerical model. Five different advance rates were studied. Parameters, such as the time required to maximum stress, the action time of the available stress, the maximum velocity of the nodes, the stress penetration time, the magnitude of the stress peak and the time duration for high stress were numerically simulated. The 2.2 m advance appeared optimum from an analysis of the simulation results. The results from numerical simulation have been validated by tests with physical models.

Investigation on the Recrystallization Behaviour of Cold Deformed MP159 Alloy

The recrystallization behaviour of cold drawn MP159 alloy was investigated by optical and TEM examinations. It is found that the platelet ε phase in the MP alloy inhibits the recrystallization,and this effect makes the MP159 alloy with high recrystallization temperature of about 920℃.This inhibition mainly comes from the increasing of the interfacial energy, which results from the change of the coherent interfaces of (0001)hcp//(111)fcc into the incoherent interfaces when the recrystallizing grain fronts bypass the platelet ε martensite. The increasing of the interfacial energy also causes the dissolution of a few segments on the ε martensite platelets, which decreases the strength of the MP alloy     

一种8毫米波变张角,半径突变多模圆锥馈源

我们研制了一种8毫米波变张角、半径突变的多模圆锥馈源。计算出其模比并推导出其辐射方向图公式;给出其在两个主平面——E平面与H平面上的辐射方向图和波束场分布特性的测试结果以及电压驻波比VSWR的测量结果;同时给出频带和旁瓣特性。分析与测试共同表明,在34.5GHz～37GHz频带里,该多模馈源的辐射图在大于24dB范围内获得幅度等化且不出现旁瓣,因此具有一定的应用价值。
