利用逐步判别分析方法识别碳酸盐岩地层岩性的方法探讨——以川东上余家坝构造石炭系地层为例

碳酸盐岩储层岩性组成复杂,仅仅依靠少量的岩心、岩屑和几条常规的测井曲线资料很难准确地展现储层岩性的纵向及横向分布特征,从而影响对储层空间分布的预测。本文以上余家坝石炭系石炭系地层的岩心、岩屑录井资料为分析样本,结合对应的常规测井资料并对其进行数学处理,处理后共有12个参数供逐步判别函数筛选,经过多次的引入与剔除,建立了各类岩石的判别函数。其中灰岩、灰质云岩、云岩选择了9个参数;云质灰岩选择了10个参数。将岩性判别结果与取心井段的岩性对照,每类岩性的判别符合率都在85.39%以上,综合符合率为91.49%。说明本方法对目的层段碳酸盐岩储层岩性的识别是可行的。     

高校实践党的群众路线研究综述

近年来,国内学者对高校贯彻实践党的群众路线的研究主要侧重于现状分析、意义论证、理念定位和对策探索等方面;对于高校如何结合新的形势实践群众路线,持续深入地开展党的群众路线教育实践活动等问题研究得较少,有待继续深入.     

Pairwise epistemic conditions for Nash equilibrium

We introduce a framework for modeling pairwise interactive beliefs and provide an epistemic foundation for Nash equilibrium in terms of pairwise epistemic conditions locally imposed on only some pairs of players. Our main result considerably weakens not only the standard sufficient conditions by Aumann and Brandenburger (1995), but also the subsequent generalization by Barelli (2009). Surprisingly, our conditions do not require nor imply mutual belief in rationality.

Employee involvement and participation: developing the concept of institutional embeddedness using WERS2004

It is widely accepted that employee involvement and participation (EIP) is a key component of the high commitment bundle of HRM, but that it can take a range of forms in practice. Much of the analysis to date has either treated different forms of EIP as a single construct or has measured EIP by virtue of its presence or absence alone. Drawing on earlier work based on the data from WERS1998 examining the link between various forms of EIP and employee outcomes such as job satisfaction and organisational commitment, the authors re-apply and extend these ideas to data from WERS2004. In particular they develop the concept of institutional embeddedness, in order argue that both the depth and breadth of EIP have important associations with commitment though not with satisfaction.

This association held for workplaces employing 25 or more workers, and here it was apparent that the more that employees are involved at workplace level – through a wider number of EIP practices that are held more frequently and include opportunities for workers to have their say – the more likely it is that investments in EIP will reap the reward of organisational commitment. For smaller establishments, given that they tend to operate with relatively few formal schemes, it is likely that managers in these workplaces find alternative ways in which to engage the workforce, and that informal EIP offer similar levels of embeddedness in these situations. A clear implication to be drawn from the findings is that, in a context of lower levels of formality within organisations (large and small), line managers are more than ever the key link between HR policy and the embodiment of actual practice at the workplace.     

保险赔偿金作为遗产继承的实务研究——关于投保人指定“法定”受益人的探讨

投保人专业知识的匮乏以及保险代理人执业的不规范和保险公司审核保单的疏漏,使得近年来投保人指定受益人为＂法定＂的情形在人身保险中时有出现。对于保单上受益人一栏为＂法定＂的情形,宜将其作未指定受益人来理解。保险赔偿金也将作为被保险人的遗产,由在事故发生时被保险人的法定继承人按《中华人民共和国继承法》予以继承。

汽车倾斜牌照中字符的定位与提取

提出了汽车图像中倾斜汽车牌照字符的定位与提取算法。该算法针对汽车牌照的灰度特点,先确定牌照的位置,并从背景中分割出来。对二值化车牌定位图通过Hough变换,计算出车牌主要直线的倾斜角度,通过插值旋转后,重新确定车牌字符的边界,最后精确地提取出汽车牌照中的字符。与其它传统的方法比较,该方法在运算速度和精确性上有一定优势。     

一种调频信号数字正交解调方法

本文提出了一种对调频信号进行数字解调的方法。该方法利用DDS产生的数字正交载波将调频信号进行数字下变频,利用FIR抽取滤波器和数字微分器在基带进行信号处理,从而得到调制信号。仿真结果显示,该方法在较低信噪比环境下能够准确地恢复调制信号。
