Obligation to prevent (O2P): Proposal for enhanced community approach to genocide prevention in Africa

As empathetic as distant nations may feel about an ongoing or looming catastrophe in a particular region of Africa, they are too far removed from the horror to grasp its gravity and impact. Geographical proximity to the atrocity, and the likelihood of its spreading to their neighbourhoods, make the communities and neighbouring countries in the imploding region the best and most effective first responders to a crisis in their own backyard. A response from ‘communal’ or ‘regional’ groups is, therefore, the most practical measure for preventing human rights violations in Africa from descending into an actual genocide or an intractable genocidal condition. A community approach to preventing genocide and other human rights abuses should serve as the foundation for a new concept of ‘moral pan-Africanism’ on the African continent in the 21^st century. This article makes an argument for this genocide prevention model and new moral concept.     

Constraining missile defence†

Assessing missile defence through the prism of offence–defence theory requires primarily an examination of legal and structural constraints on future development. New weapons technology is frequently cited as having the most critical impact on the offence–defence balance. Yet, the method for assessing the introduction of a new weapons technology tends to neglect projected maturity and instead focus excessively on the initial rudimentary capabilities. It is argued here that the North Atlantic Treaty Organisation’s (NATO’s) missile defence is set to incrementally become more advanced in terms of quality, quantity and mobility, which is supported by a strategy that is increasingly favouring offence. As the system gradually enhances the offensive advantage vis-à-vis Russia, NATO categorically rejects any legal or structural constraints on future deployments.     

带优先级的单类型航空弹药转运多目标规划模型

针对航母航空弹药转运过程非常复杂、涉及设备多、要求高的特点,在对其流程进行细致分析的基础上,将其抽象为一个两阶段多目标规划问题。同时,深入分析了转运过程中的各种约束条件、构建了该问题的两阶段优化模型。建模时,不仅考虑了武器升降机的有效利用、弹药量的合理分配等因素,还考虑了转运时对于不同类型弹药转运优先级与停机区弹药需求优先级的要求。通过模型优化,在满足转运优先级要求的基础上,能有效提高航空弹药的转运效率。

基于SWOT分析的我国海上方向空中安全形势及对策措施

海上方向是强敌对我实施战略围堵和遏制的主要方向。随着美国国防战略重回大国竞争,其遏制中国的手段推陈出新,尤其是在海空方向对我施压强度频度与日俱增。文章运用SWOT方法对我国海上方向空中安全形势进行了全面分析,认为优势体现在联合作战指挥体制、国防动员能力、列装新型防空武器等方面,劣势体现在战场建设滞后、预警探测拦截打击能力不足等方面,机遇体现在中美共识与相对稳定的周边环境,威胁体现在强敌对我的侦察威慑、空天打击、海空封锁。通过构建我国海上方向空中安全的SWOT分析矩阵,提出要进一步深化改革,加强军队与地方、平时与战时、作战力量和作战环节的“三个统筹”,发展新型防空、预警装备,以及加强沿海防空战场建设等。     

A split target detection and tracking algorithm for ballistic missile tracking during the re-entry phase

In the re-entry phase of a ballistic missile, decoys can be deployed as a mean to overburden enemy defenses. This results in a single track being split into multiple track-lets. Tracking of these track-lets is a critical task as any miss in the tracking procedure can become a cause of a major threat. The tracking process becomes more complicated in the presence of clutter. The low detection rate is one of the factors that may contribute to increasing the difficulty level in terms of tracking in the cluttered environment. This work introduces a new algorithm for the split event detection and target tracking under the framework of the joint integrated probabilistic data association (JIPDA) algorithm. The proposed algorithm is termed as split event-JIPDA (SE-JIPDA). This work establishes the mathematical foundation for the split target detection and tracking mechanism. The performance analysis is made under different simulation conditions to provide a clear insight into the merits of the proposed algorithm. The performance parameters in these simulations are the root mean square error (RMSE), confirmed true track rate (CTTR) and confirmed split true track rate (CSTTR).
