在面向方面软件开发Theme方法的基础上引入用例驱动技术,其中用例技术实现软件模块化,面向方面技术封装横切关注点,从而形成一种用例驱动的面向方面软件开发(UCD/Theme)方法。通过分析面向方面模块的动态特性在编织过程中可能产生的冲突,提出了一种扩展UML的面向方面模块动态特性编织时的冲突解决方法。通过ATM案例说明了该方法的应用。  相似文献

锤锻与织布噪声对听力损害的比较研究   总被引:1,自引:0,他引:1  
选133名锤锻工和95名织布工为研究对象。现场噪声参数比较结果:锤锻声最大线性峰值(122.6~142.4dB)和峰值的变化以及A计权慢档均方根值(L_(AS))的全距,均明显大于织布声;峰值因数(L_(AP)—L_(AS))分布也较织布声宽;但锤锻工平均日接噪时间(2.4小时)明显短于织布工。根据锤锻与织布工4kHz实测和预期噪声性永久听阈移中值(N_0.50)间的比较及两工种间实测N_0.50的比较结果,均未见明显差异;而锤锻工不同的累积接噪剂量与4kHz的N_0.50之间有显著相关。看来锤锻噪声对工人听力的损害,尚符合等能量假说原理。  相似文献

为了及时解决由于关注点横切所产生的“代码交织”与“代码散布”问题,提出了一种基于Statecharts的面向方面软件设计方法,并利用线性时态逻辑验证了编织过程的有效性。此外,为了验证方面Statecharts的介入是否破坏了基本Statechart的相关行为,引入扩展层次自动机解释面向方面Statechart的操作语义,使用线性时态逻辑描述系统的关键属性。最后通过一个案例证明了该设计方法的可行性。  相似文献

Basho-fu (Musa liukiuensis) weaving has long been part of the cultural identity of Ogimi villagers and has continued in the village as a cottage industry despite its almost complete disappearance throughout the rest of the Ryukyu archipelago. It has survived largely due to the concerted efforts of a few villagers and is now carried on mainly by middle-aged and older women. Almost every elderly woman in Ogimi has at least some experience in basho-fu weaving, and most still participate in some stage of the production process. Aged women form the bulk of the core group of workers that carries out the labor-intensive u-umi (spooling) and u-biki (fiber-cleaning) activities. Without this core group of elderly women, the whole production process would be in jeopardy. Thus, older women in Ogimi play a key role as valued workers in maintaining the basho-fu production process. In exchange for their continued participation, these elderly women receive symbolic capital in the form of respect and honors, as well as wages for their labor. We argue that participating in traditional basho-fu weaving helps these older women maintain an active engagement with life as healthy and productive members of society, a role that has been culturally sanctioned and has taken on moral import in Japan's rapidly aging society. Interestingly, "doing basho" may be considered one means to help achieve successful aging in this particular cultural context.  相似文献

The weaving welding process is a key method used to improve the welding quality in multi-layer and multi-pass welding processes using robots. However, the heat-input fluctuation in the weaving welding process restricts its development. In this paper, we developed a novel weaving welding control algorithm to maintain a constant weld heat input through velocity adaptive planning. First, the heat consumption during the weaving welding was modeled to describe the influence of weaving parameters on the weld heat input. Then, based on the obtained relationship between the weld heat input and the weaving parameters, a velocity-adaptive trajectory planning strategy was proposed by leveraging the transformation matrix derived from the relationship between the workpiece and the robot co-ordinate systems. The simulation and experimental results show that the proposed strategy can compensate for the weaving parameters to maintain a constant heat input based on heat consumption and improve the quality of the robotic multi-layer and multi-pass welding process.  相似文献
