半自动输弹机模糊控制系统

针对某半自动输弹机系统实际的输弹过程,提出了模糊控制系统的控制方案,根据本输弹机系统的模型设计了模糊控制参数。运用Matlab/Simulink仿真软件分别对采用模糊控制的系统和采用普通PID控制算法的系统进行仿真,得到各系统的单位阶跃响应曲线图和抗干扰信号图。对输弹机进行上炮试验,对比采用模糊控制的系统和采用普通PID控制算法的系统的实验结果,得到采用模糊算法的输弹机系统的卡膛一致性能很好的满足要求,具有一定的实践意义。     

战略后方仓库综合技术保障中心建设方案评估

构建了后方仓库综合技术保障中心建设方案综合评估指标体系,先运用多人层次分析法对评价指标进行主观赋权,再对指标权值加以客观修正,从而得到较为客观准确的综合权重,最后运用模糊综合评价法对若干备选方案进行评判,得到各备选方案的评级结果,并从中选择最优方案。算例分析表明,该方法能够较好地适用于建设方案的评价,得出的量化描述结果可以作为建设方案评判与选择的参考依据。     

Turkey-Africa alliance: Evolving patterns in security relations

ABSTRACT

Turkey has maintained its strategic relations with Africa at the highest level under recent AK Party governments in the field not only of low politics but also of high politics. For example, it opened its largest overseas military base in Somalia in 2017 and signed military, defense and security pacts with more than 25 African countries. This article traces the deep historical and cultural relations with Africa behind its newly evolving foreign policy identity, arguing that its booming economic power has been a significant driving force in shaping a new security strategy. It examines what the growing security involvement means for both Turkey and Africa in order to contribute to the relevant literature through a holistic approach from both theoretical and conceptual perspectives.     

Re-thinking the Unthinkable: Arms Control in the Twenty-First Century

ABSTRACT

Since the end of the Cold War, arms control proponents tried to make the case for deep nuclear reductions and other forms of security cooperation as necessary for strategic stability. While different versions of strategic stability analysis did sometimes produce innovative proposals, constructive negotiations, and successful ratification campaigns in the past, this analytical framework has become more of a hindrance than a help. Treating arms control as a predominantly technical way to make deterrence more stable by changing force structure characteristics, military operations, relative numbers of weapons on either side, or total number of nuclear weapons gives short shrift to political factors, including the fundamental assumptions about world politics that inform different arms control logics, the quality of political relations among leading states, and the political processes that affect negotiation, ratification, and implementation. This article compares two logics for arms control as a means to enhance strategic stability, one developed by the Cambridge community in the 1960s and one used by the Reagan administration and its successors, with current perspectives on strategic stability in which flexibility and freedom of action are preferable to predictability and arms control. It also contrasts what the Barack Obama administration has tried to achieve through strategic stability dialogues with Russia and China with how they envision security cooperation. It then presents an approach developed during the Cold War by Hedley Bull for thinking about both the technical and the political dimensions of arms control, and suggests that the logic of Cooperative Security (which shares important features with Bull's approach) is a more appropriate and productive way to think about arms control in the twenty-first century than strategic stability analysis is.

多彩光谱教育理论与音乐、绘画融通的教学实践

音乐与绘画的融通问题长期以来一直缺乏充分、深入的研究,在教育领域也是如此。本文援引多个教学案例,借鉴多彩光谱教育理论,从教学目标、教学设计、教学步骤、实施方法诸方面来阐释和解决音乐与绘画的融通在教学实践中出现的问题。     

地空导弹发控系统寿命预测的组合模型

将灰色系统理论和BP神经网络有效地结合起来,建立了灰色BP神经网络的组合预测模型,并采用遗传算法对该模型进行优化。为了验证优化后模型的有效性,采用灰色BP神经网络的预测结果进行对比分析。实际数据的预测结果表明,优化之后的模型比单独采用灰色BP神经网络,具有更小的均方差(MSE,Mean Square Error),对发控系统剩余寿命(RUL,Remaining Useful Life)也具有更高的预测精度。     

新征程军事指导理论创新发展

十八大以来,习主席关于国防和军队建设重要论述,体现了我党军事指导理论的创新发展,既是习主席治国理政思想在军事领域的重要体现,也处处体现了辩证唯物主义的思想方法。学习贯彻习主席关于国防和军队建设的重要论述,必须牢牢把握其思想精华,把意志和力量凝聚到实现中国梦强军梦上来,推动国防和军队建设的创新发展。
