柔模泵筑混凝土支护在红柳煤矿主斜井表土段的尝试

柔模泵筑混凝土支护已在隧道施工中得到应用，矿山工程中尚未进行尝试，柔模泵筑混凝土支护以保护阿岩自身的完整性，充分发挥围岩自身的承载能力为基本出发点。红柳煤矿主斜升进行柔模泵筑混凝土支护试验，并取得了成功，对井筒的安全、快速施工意义重大。     

所有最短路径的求解算法

本文提出了一种求所有最短路径的算法,能高效地求出一个顶点到其它各顶点的所有最短路径。此外,我们用C语言设计的相应程序验证了此算法。     

基于位运算的属性核约简

属性约简是粗糙集理论中的一个重要内容,其核心任务是得到属性集的核,它是属性约简的基础,文中提出了基于位运算的新的核约简算法。与传统算法相比,其速度更快,效率更高,且易于计算机实现,为扩展粗糙集的应用提供了理论基础。     

Vague集的新模糊熵

对于Vague集模糊熵应该既有Vague集的未知性又有Fuzzy集的不确定性。首先在给出了反例证实现有方法在某些情况得出的结果与实际结论不一致情况下,提出了一个真正考虑了两种因素的改进的Vague集模糊熵公理化定义,然后给出一种Vague集模糊熵的新计算公式,最后通过定理证明和实例分析,指出它确实同时考虑到Vague集的未知性和不确定性,从而证明所给出Vague集模糊熵的定义是更加合理的。     

A mathematical morphological approach for region of interest coding of microscopy image compression

A novel mathematical morphological approach for region of interest(ROI) automatic determination and JPEG2000-based coding of microscopy image compression is presented.The algorithm is very fast and requires lower computing power,which is particularly suitable for some irregular region-based cell microscopy images with poor qualities.Firstly,an active threshold-based method is discussed to create a rough mask of regions of interest(cells).And then some morphological operations are designed and applied to achieve the segmentation of cells.In addition,an extra morphological operation,dilation,is applied to create the final mask with some redundancies to avoid the"edge effect"after removing false cells.Finally,ROI and region of background(ROB) are obtained and encoded individually in different compression ratio flexibly based on the JPEG2000,which can adjust the quality between ROI and ROB without coding for ROI shape.The experimental results certify the effectiveness of the proposed algorithm,and compared with JPEG2000,the proposed algorithm has better performance in both subjective quality and objective quality at the same compression ratios.     

一种改进的可区分矩阵与求核方法

本文针对Hu方法存在的问题,提出了一种改进的可区分矩阵与求核方法,并证明了该方法的正确性。该方法不仅克服了Hu方法的不足,而且指出了Hu方法出错的根本原因。
