Axis2与NET平台间Web服务安全交互研究与实现

Web服务基于一系列开放的标准技术,具有松散耦合、语言中立、平台无关、互操作性的优点。近年来,在武警部队信息化建设中,很多平台都构建了Web服务。但由于Web服务的各个平台对WS—Security规范的支持不统一,这就为全部队涉及不同业务部门的异构平台web服务的安全交互带来了问题。通过分析NET和Axis2Web服务平台对WS—Security规范的支持,提出一个方案来解决多个异构Web服务平台之间的安全交互问题,最后通过实验证明了该方案的可行性。     

执勤案例库在武警勤务教学中的运用

案例教学在国外较为流行,哈佛大学商学院、法学院等一些高级专业课程已经取得较大成功。我国高等院校已经基本普及,军队院校案例教学也取得一定成果。执勤案例库可以有效提高学员对勤务理论知识的理解和掌握;运用案例库进行案例教学能增强教学针对性、提升实战能力;执勤案例库可以培养学员分析判断、综合处理复杂问题的能力。所以,必须重视武警执勤案例库建设,并充分运用案例库进行教学。     

火箭弹卷弧尾翼的轻量化研究

针对火箭弹卷弧尾翼在特定气动载荷下的轻量化问题,基于结构动力学理论,依托ABAQUS非线性有限元软件,建立了火箭弹卷弧尾翼的有限元模型。通过对比碳纤维复合材料(CFRP)和合金钢材料的卷弧尾翼的有限元分析,得出了碳纤维复合材料在满足强度和刚度的要求下,使卷弧尾翼减重达80%。该方法为火箭弹卷弧尾翼的轻量化设计提供了一种参考和借鉴。     

具有时变时间延迟的混沌保密通信同步方法研究

针对固定时间延迟及时变时间延迟系统,提出了同步控制方案,在实现同步后能有效解决传输时延对保密通信的影响.利用线性矩阵不等式方法设计了同步控制器,应用Lyapunov方法分析了同步误差的收敛性,并运用Schur补引理证明了全局渐近稳定点的存在.     

Military expenditure,economic growth and structural instability: a case study of South Africa

This paper contributes to the growing literature on the milex-growth nexus, by providing a case study of South Africa and considering the possibility of structural breaks by applying newly developed econometric methods. Using full sample bootstrap Granger non-causality tests, no Granger causal link is found between military expenditure and GDP for 1951–2010, but parameter instability tests show the estimated VARs to be unstable. Using a bootstrap rolling window estimation procedure, however, finds evidence of bidirectional Granger causality in various subsamples. This implies standard Granger non-causality tests, which neither account for structural breaks nor time variation may be invalid.     

The Impact of the Unemployment Rate on Attrition of First-Term Enlistees

This study examines the effects of home-state unemployment rates on attrition behavior of Navy enlistees for successive career windows during the first term of service: the first 6?months, the second 6?months, the second year, and the third year of service. The results indicate that attrition is negatively associated with changes in the local unemployment rate during the first three career windows covering two years of service. However, after two years of service, the estimated effect of the unemployment rate becomes insignificant for most groups of sailors. This is likely because sailors with the poorest job matches are sorted out early in the first term of service.     

Detecting Problems in Military Expenditure Data Using Digital Analysis

The UN asks governments to report key figures of their annual military budgets with the aim of creating trust among member states. This goal can only be achieved if the data reported is accurate. However, although there are many reasons for governments to falsify data, the UN does not check for manipulation. In this paper, we apply Benford’s law to the military expenditure data of 27 states taken from the UN register. Our analysis of the first digits shows that the states with the greatest deviations from the expected Benford distribution and therefore the lowest data quality are the USA and the UK.     

Does Military Spending Really Matter for Economic Growth in China and G7 Countries: The Roles of Dependency and Heterogeneity

This study revisits the causal linkages between military spending and economic growth in China and G7 countries (i.e. Canada, France, Germany, Italy, Japan, the UK, and the USA) by focusing country-specific analysis for the period 1988–2010. The panel causality analysis, which accounts for both cross-country dependency and heterogeneity across countries, is employed in this study. Our results find evidence of the neutrality hypothesis for Italy, France, and Germany, the military spending–growth detriment hypothesis for both Canada and the UK, and one-way Granger causality running from economic growth to military spending for China. Furthermore, we find a feedback between military spending and economic growth in both Japan and the USA. Thus, our results do not support that one size fits all.     

Military Spending and Economic Growth: The Case of Iran

Over the last decade, the Iranian Government budget on military has been higher than the average of the world. The current increasing international sanctions aim to reduce the military capabilities and capacities of the Iranian Government. We analyze the response of the Iranian economy to shocks in its military budget from 1959 to 2007, using impulse response functions and variance decomposition analysis. The Granger causality results show that there is unidirectional causality from the military spending growth rate to the economic growth rate. The response of income growth to increasing shocks in the military budget is positive and statistically significant.
