Combined with the characteristics of the digital circuit curriculum,this paper shows a full performance of the product for the CAI system of the digital circuit curriculum(CSDCC) based on simple MPC. CSDCC includes four parts:system design, classroom teaching, ICAI system, experiment teaching. From construction to details, the system design module is designed to complete the design of he system is bottom database.Providing three kinds of teaching style : commonness, practice, hyperText , the classroom teaching module completes teaching for the whole contents of and the ICAI system module gives the product, which is the ICAI system of the K map Simplification of Logical Function. 相似文献

The kernel function of kernel estimator for regression function is often defined with compact support, the moment of Y is bigger than one. The convergence rate of the improved kernel estimator is discussed under the improved kernel function. The result is also discussed under random censorship. The class of applicable kernels include those having unbounded support and even not integral .The condition of moment of Y is discarded under the improved kernel estimator. The results are wholly the same as usual and generalize the relative results of the paper . 相似文献

The principles of image monitoring system for bridge's deformation is proposed. Based on linear system theory, the whole system comprises linear shift-invariant system composed of atmosphere, optical sub-system and camera. The modulation transfer function of each component is analyzed, especially for the atmosphere. For a special system, modulation transfer functions on different weather condition such as sunny, cloudy, rainy and fogy weather are analyzed. 相似文献

Spiral case is the core structure of powerhouse,therefore,it is critical to obtain its accurate stress and strain.Simplified algorithm is adopted to analyze the mechanical characteristics of preloading water-filled spiral case of a large hydropower project.The numerical results show that the adoption of preloading water-filled spiral case structure is feasible.The maximum stress of surrounding concrete mainly lies in the top of spiral case structure at various sections.The suitable internal pressure is 1.9MPa.The stress of surrounding concrete of spiral case is mainly caused by water pressure,and the effect of upper loading is limited,which is only about 5% to 24%. 相似文献

In this paper, the fundamental formula of matrix function is discussed. The author puts forward a new method of solution of two-rank linear transient respond, using the fundamental formula of matrix function. The method can be spread and applied to solution process of high rank linear circuit transient respond and is superior to that of traditional solution. 相似文献
