Resource rents,institutions, and violent civil conflicts

Natural resources have been blamed for inducing slow growth and sparking civil conflicts and violence. This paper first develops a model to account for the hazard of armed civil conflicts as a manifestation of the natural resource curse, which is mediated by the quality of both economic and political institutions. We then use recently published data on institutional quality and natural resource rents to measure the potential impact of the resource curse on violent civil conflicts using a panel of data for over 100 countries in the period 1970–2010. Our model explicitly accounts for the role of good economic and political institutions in deterring the recourse to violence as well as the extent to which they might weaken the resource rents effect.     

Advancing “Defence-in-depth”: intelligence and systems dynamics

This article aims to encourage the fostering of more systems thinking, and its greater exploitation, within the domain of contemporary intelligence. With particular focus on “micro systems thinking” and with reference to key intelligence processes, such as intelligence analysis, the utility of many systems dynamics within the intelligence context seeks to be further revealed. Through their greater collective harnessing, including up to “System of Systems” (“SoS”) dynamics, and promoting all that they can offer, more sophisticated overarching operational-to-strategic/policy “ends,” notably that of “defence-in-depth,” can be viably further advanced in a sustainable manner into the future. Arguably, a much-needed transformative impact on contemporary intelligence can also be increasingly realised through comprehensively engaging in and with more systems and SoS thinking. Aiding civil protection tasks, crisis management, emergency planners, and civil contingency practitioners likewise gain.

飞行器试验多测控目标发射零点应急处理方法

飞行器飞行试验任务中,发射零点T0是整个测控系统启动运行的基准点,是保证测控系统有条不紊正常工作的关键因素。特别是执行多个测控目标连射飞行试验任务,多个发射零点的正确处理更是关乎试验任务的成败。在分析发射零点形成机制基础上,对发射零点在指控系统实时测控软件中的处理方法进行了研究,提出了一种实时测控软件重启后重新获得多测控目标正确发射零点的应急处理方法,解决了试验过程中一旦实时测控软件因重大软件故障导致初始发射零点丢失的问题,保障了试验任务的顺利进行。     

Model parameter estimation and residual life prediction for a partially observable failing system

We consider a partially observable degrading system subject to condition monitoring and random failure. The system's condition is categorized into one of three states: a healthy state, a warning state, and a failure state. Only the failure state is observable. While the system is operational, vector data that is stochastically related to the system state is obtained through condition monitoring at regular sampling epochs. The state process evolution follows a hidden semi‐Markov model (HSMM) and Erlang distribution is used for modeling the system's sojourn time in each of its operational states. The Expectation‐maximization (EM) algorithm is applied to estimate the state and observation parameters of the HSMM. Explicit formulas for several important quantities for the system residual life estimation such as the conditional reliability function and the mean residual life are derived in terms of the posterior probability that the system is in the warning state. Numerical examples are presented to demonstrate the applicability of the estimation procedure and failure prediction method. A comparison results with hidden Markov modeling are provided to illustrate the effectiveness of the proposed model. © 2015 Wiley Periodicals, Inc. Naval Research Logistics 62: 190–205, 2015

机翼不对称损伤飞机在大侧滑角下的操稳特性研究

对某小型电动无人机(以下简称SEPUAV)在其左翼破损40%面积矩下的操稳特性进行详细分析。首先在此损伤下典型大侧滑角定常工作点附近进行特殊的小扰动线性化,然后进行特征根和飞行运动模态的分析;其次对此特殊构型SEPUAV进行操稳特性、时频响应特性进行分析。分析结果表明:左翼破损40%面积矩SEPUAV出现特有运动模态并影响全部纵侧向运动状态的响应;部分传递函数出现较多非最小相位零点从而导致初始响应发生反向;部分通道的Bode图中出现多个波峰波谷并有相角提前等现象。分析结果对后续容损飞行控制器的设计起到铺垫的作用。
