对高校德育的新思考、新突破、新发展--学习《加强和改进大学生思想政治教育》和《讲话》心得

中共中央关于加强和改进大学生思想政治教育工作的一系列部署,是我党对新形势下高校德育工作作出的新思考、新突破、新要求,围绕“培养什么人、如何培养人”这个社会主义教育事业发展的根本问题,在德育理念、目标要求和实施方略三个方面取得了一些新的突破,提出了一些新的主张,进一步丰富和发展了高校德育理论。     

炮兵火力计划备选方案的评估优选研究

评估优选是决策3＋过程中非常重要的步骤，直接决定着最终方案的确定。在分析研究炮兵火力计划方案的评估指标的基础上，研究建立了指标值的计算模型和整体方案的评估模型；指标的权重是指标在决策中相对重要程度的一种客观反映和主观评估的综合度量，论文提出了将客观的熵权法和改进的主观屡次分析法相结合共同确定权重的方法。给出了能实现方案评估的系统的体系结构，仿真验证，这种方法确定评估指标的权重是可行的，客观赋权法和主观赋权法相互修正，权重值更合理。

分层的基于身份的动态门限签名方案

提出了一个分层的基于身份的动态门限签名方案.方案具有分层的PKG结构，低层PKG可以分担高层PKG的秘密信息产生和身份认证的任务；同时具有动态安全的特性，将签名的整个生命周期分成若干时间段，每个时间段都对密钥份额进行更新，更新后的份额重构的密钥保持不变.使用了离散对数相等的知识证明协议，以保证部分签名的正确性，并证明了方案的正确性、不可伪造性和鲁棒性.给出了方案的一些扩展.

Multi secret image color visual cryptography schemes for general access structures

In the proposed visual cryptography schemes for general access structures, the single secret image black-and-white visual cryptography schemes with meaningful shares have been constructed, in which the shares are innocent looking images. The meaningful shares have not been realized in single secret image color schemes; neither have the multi secret images color schemes. In this paper, the multi secret images color visual cryptography schemes for general access structures with meaningful shares are constructed by the method of matrix concatenation, the pixel expansion is obtained, and the validity of the scheme is proven. In our scheme, the different combination of meaningful color shares can be used to recover distinct color secret images. The multi secret images black-and-white visual cryptography scheme is a special case of our color scheme.     

Scheme construction with numerical flux residual correction (NFRC) and group velocity control (GVC)

For simulating multi-scale complex flow fields like turbulent flows, the high order accurate schemes are preferred. In this paper, a scheme construction with numerical flux residual correction (NFRC) is presented. Any order accurate difference approximation can be obtained with the NFRC. To improve the resolution of the shock, the constructed schemes are modified with group velocity control (GVC) and weighted group velocity control (WGVC). The method of scheme construction is simple, and it is used to solve practical problems.     

Comparison of the Hadley cells calculated from two reanalysis data sets

The Hadley cell (HC) is a vertical circulation cell with the largest scale, the strongest intensity, and the longest studying history in the atmosphere[1]. The common ascending leg of Northern and Southern Hemispheric HCs corresponds to the equatorial tro…
