使用i~*体系进行面向目标的需求分析

目标在需求工程过程中起着重要的作用.目标对需求说明提供了一个完整的标准;如果所有已陈述的目标被需求说明满足,则需求说明就是完整的.文章采用了Eric Yu的i*框架,它是一个对早期需求的模型化的体系,用它作为在整个生命期中模型化后期需求、结构和详细设计以及执行的基础.     

A template of rat brain based on fMRI T*2 imaging

The development of functional magnetic resonance imaging (fMRI) technology has made it possible to carry out functional brain imaging experiments in small animals. Usually, group data is required to form the assessment of population, which can not only increase the sensitivity of the overall experiment, but also allow the generalization of the conclusion to the whole population. In order to average the signals of functional brain images from different subjects, it is necessary to put all the mapping images into the same standard space (template image). However, up to now, most animal brain templates remain unavailable and it must be done by ourselves. In this study, a template image based on the brains of eight male Wistar rats is obtained, and it is successfully used in our present Alzheimer disease (AD)-like rat model studies as template for spatially normalizing images to the same stereotaxical space. The fMRI results processed with statistical parametric mapping (SPM99) software are in agreement with the results from immunohistochemical experiment, which proves that this method is universally applicable to the pathologic models of other small animals and to human brain lesion studies.
