面向“卓越工程师”培养的课程体系和教学内容改革

课程体系和教学内容改革是成功地进行卓越工程师培养必须完成的一项至关重要而又具有挑战性的关键工作。本文根据“卓越工程师教育培养计划”的总体要求,面向卓越工程师的培养,分析和研究相应的课程体系和教学内容改革。首先分析课程体系的价值取向,其次研究课程体系应采用的结构形式,最后系统地探讨课程体系的整合与重组,以期为“卓越计划”...     

基于分治、剪枝和蚁群算法求解最大团问题

最大团问题是经典的NP-hard问题,对该问题求解方法的研究在理论上,实践上都具有一定的意义。蚁群算法已成功地求解许多组合优化难题。本文使用分治法,将图分解成子图,对各子图应用蚁群算法求解,并根据目前求得的最优解的值对各个子图进行剪枝,去除对求解没有意义的点,提出基于分治、剪枝和蚁群算法求解最大团问题的算法。它减小了问题的求解规模,使求解容易。实验取得了较好的结果。     

论高校心理健康教育与思想政治教育的整合

高校心理健康教育与思想政治教育属于教育工作中不同的实践,但又有着共同的思想起源,一致的教育根本目标,共同的教育和研究对象,以及相互交叉相互渗透的教育内容和相似的教育途径和教育方法,可以在目标、方法、队伍建设和教学形式等方面进行整合。     

医科院校师资英语口语培训项目研究

高校专业课向双语教学和全英语教学方向发展的教学要求对专业课教师的英语水平提出了新的挑战。为适应时代发展需要、培养高素质人才并提高师资队伍水平,基于校本资源的师资英语口语培训班成为解决这一问题的有效途径。从哈尔滨医科大学师资英语口语培训项目的办学宗旨、办学特色、考核体系等方面着眼,介绍培训项目的实施情况,并对项目的进一步开展和实施提出展望。     

学习型社会背景下成人终身学习模式探究

构建成人终身学习的学习型社会是我国全面建设小康社会的重要目标。学习型社会为成人学习者提供了一个良好的终身学习环境,促进了成人学习不断向全民化、终身化方向发展。通过成人学习者与普通学生不同的心理特征和学习特征的对比分析,结合终身学习的特点提出了成人终身学习的四个模式,即主动式学习模式、发现式学习模式、合作式学习模式、开放式学习模式。最后,在四个模式的基础上进行分析和探讨。     

运用党的历史经验深入开展高校创先争优活动的思考——以百色起义精神为例

中国共产党建党90周年,是全心全意为人民服务,不断创先争优的90年。邓小平等老一辈无产阶级革命家领导的百色起义,给当前党的创先争优活动留下极其宝贵的经验。通过探讨百色起义精神的内涵以及深入开展高校创先争优活动的主要路径,得出有现实意义的启示。     

Measuring scientific contributions with modified fractional counting

We develop and propose a new counting method at the aggregate level for contributions to scientific publications called modified fractional counting (MFC). We show that, compared to traditional complete-normalized fractional counting, it eliminates the extreme differences in contributions over time that otherwise occur between scientists that mainly publish alone or in small groups and those that publish with large groups of co-authors. As an extra benefit we find that scientists in different areas of research turn out to have comparable average contributions to scientific articles. We test the method on scientists at Norway’s largest universities and find that, at an aggregate level, it indeed supports comparability across different co-authorship practices as well as between areas of research. MFC is thereby useful whenever the research output from institutions with different research profiles are compared, as e.g., in the Leiden Ranking. Finally, as MFC is actually a family of indicators, depending on a sensitivity parameter, it can be adapted to the circumstances.     

孔隙分布不均匀性对渗透率影响的MRTLBM法研究

孔隙率与渗透率是多孔介质非常重要的属性参数,采用MRT LBM研究孔隙率损失与渗透率损失相关性以及同孔隙率异构孔隙对渗透率特性的影响。结果表明：当存在使孔隙率均匀变小的沉积、沉降或结焦等因素时,渗透率损失率是孔隙率损失率的2倍左右;同孔隙率异构多孔体中,渗透率有巨大差异;同孔隙率异构多孔体中最大孔喉最小孔喉比越大渗透率越小;同孔隙率多孔体中迂曲度越大渗透率越小。     

Mean-square integral input-to-state stability of nonlinear impulsive semi-Markov jump delay systems

In this paper, the problem of mean-square integral input-to-state stability of nonlinear impulsive semi-Markov jump delay systems is investigated. By using stochastic Lyapunov functions together with Razumikhin technique, some sufficient conditions for mean-square integral input-to-state stability for a class of nonlinear impulsive semi-Markov jump delay systems are developed. In particular, the results obtained generalize and complement some recent literature. Finally, some numerical examples are given to show the effectiveness and advantages of the proposed techniques.     

Linear quadratic open-loop Stackelberg game for stochastic systems with Poisson jumps

This paper is concerned with the finite horizon linear quadratic (LQ) Stackelberg game for stochastic systems with Poisson jumps under the open-loop information structure. First, the follower solves a LQ stochastic optimal control problem with Poisson jumps. With the aid of an introduced generalized differential Riccati equation with Poisson jumps (GDREP), the sufficient conditions for the optimization of the follower are put forward. Then, the leader faces an optimal control problem for a forward-backward stochastic differential equation with Poisson jumps (FBSDEP). By introducing new state and costate variables, a sufficient condition for the existence and uniqueness of the open-loop Stackelberg strategies is presented in terms of the solvability of two differential Riccati equations and a convexity condition. In addition, the state feedback representation of the open-loop Stackelberg strategies is obtained via the related differential Riccati equation. Finally, two examples shed light on the effectiveness of the obtained results.
