This paper presents a method for robust tolerance design in terms of Process Capability Indices (PCI). The component tolerance and the suitable manufacturing processes can be selected based on the real manufacturing context. The robustness of design feasibility under the effect of uncertainties is also discussed. A comparison between the results obtained by the proposed model and other methods indicates that robust and reliable tolerance can be obtained. 相似文献

Luquire et al.'s impedance change model of a rectangular cross section probe coil above a structure with an arbitrary number of parallel layers was used to study the principle of measuring thicknesses of multi-layered structures in terms of eddy current testing voltage measurements. An experimental system for multi-layered thickness measurement was developed and several fitting models to formulate the relationships between detected impedance/voltage measurements and thickness are put forward using least square method. The determination of multi-layered thicknesses was investigated after inversing the voltage outputs of the detecting system. The best fitting and inversion models are presented. 相似文献

This paper proposes novel multi-layer neural networks based on Independent Component Analysis for feature extraction of fault
modes. By the use of ICA, invariable features embedded in multi-channel vibration measurements under different operating conditions
(rotating speed and/or load) can be captured together. Thus, stable MLP classifiers insensitive to the variation of operation
conditions are constructed. The successful results achieved by selected experiments indicate great potential of ICA in health
condition monitoring of rotating machines.

高校图书馆图书采购招标中应关注的二个重要问题 总被引：1，自引：0，他引：1
本文指出了高校图书馆图书采购招标给图书采购造成的藏书质量下降、藏书结构不合理、读者满意度降低的现象,分析了形成原因,提出通过加强图书馆对图书采购招标过程的主动参与、适当引导,从而选择符合文献资源建设规律的图书供应商,并在图书采购合同执行过程中,进行全程监督、检查,及时发现书商在图书供应方面存在的问题,规避可能对藏书建设不利的因素,提高图书采购的订到率、订全率,为图书馆建立能满足读者阅读需求的藏书体系。 相似文献

王国维《人间词话》作为中国古代文论的一大高峰,其中提到的境界说对中西文论的思想都有很大的继承与发展。境界说之实质就是在求文学之真的审美特性,其精神核心就是真情。其中这一审美思想与中国古代的道家文化所追求的“自然”,以及古代文论中“文以载道”的思想,还有西方叔本华、尼采的哲学思想都有着密切的关系。 相似文献
