In Component-based Software Engineering (CBSE), the construction of cost-optimal component systems is a nontrivial task. It requires not only to optimally select components and their adaptors but also to take their interplay into account. In this paper, by employing methods from the area of compiler construction and especially optimizing code generation, we present a unified approach to the construction of component systems, which allows us to first select an optimal set of components and adaptors and afterwards to create a working system by providing the necessary glue code. With our two case studies, we demonstrate that our approach is efficient and generally applicable in practical scenarios. 相似文献

在参考张量投票理论的基础上,结合二次误差简化算法,提出一种边界特征保持的几何网格模型分级二次误差简化算法.首先根据张量投票理论对三角网格顶点进行面点、边点、角点类型分类;然后对各边对按照二次误差简化算法进行边折叠代价计算;再将分类顶点按照设定的等级权重加入边对折叠代价中,从而保证渐进式简化过程中能够对顶点进行分级简化.实验结果表明,该算法不但能实现渐进简化,而且能按需保留模型的整体特征和细节特征. 相似文献

Memory updating was one theme of the sixth annual workshop of the IEEE Computer Society's Technical Committee on Computer Elements, held last June in Vail, Colorado. As is traditional with many Computer Society workshops, this report is a collection of unattributed comments from individual workshop attendees whose anonymity was preserved in order to encourage a candid exchange of points of view. 相似文献

This article discusses the author's experiences in transitioning from a “tech-heavy” program in English studies to a “tech-light” program. The specific natures of “tech-heavy” and “tech-light” programs are defined and discussed. Suggestions drawn from the author's experience for teaching, doing research, and changing access and attitude at the institutional level are provided. 相似文献

First impressions do count, especially to new employees. By properly managing first impressions and the entire orientation process of new hires, IS managers can create an organization in which employees are more productive and to which they feel more connected. the most effective employee orientation programs are often the most creative ones, and this column helps IS managers be innovative when orienting new staff members. 相似文献
