Revisiting the Defense–Growth nexus in European countries

This study revisits the long run and dynamic causal linkages between defense spending and economic growth in 15 selected European countries for the period 1988–2010 by utilizing recent developments in non-stationary panel data analysis. To this end, the series properties of per capita defense spending, per capita real capita stocks, and per capita real GDP are investigated by the panel unit root tests with and without breaks that support evidence on unit root. The panel cointegration tests with and without breaks are also subsequently employed to investigate whether there exists a long-run equilibrium relationship between these three variables. Finally, our causality analysis from panel vector error-correction model suggests that there is a feedback relation between real capital stock and real GDP in both short and long run, a one-way Granger causality running from real GDP to defense spending in both short and long run, and defense spending only Granger causes real capital stock in the long run.

国外潜航器水下隐蔽导航定位方法探析

针对潜航器自主惯性导航误差随时间不断增大的问题,研究了基于运载器、信标中继、海底固定基站的国外潜航器的典型导航定位方法。通过水声通信方式,运载器、信标中继站将其卫星精确定位数据发送至潜航器,或海底固定基站接收到潜航器发射唤醒信号后,量测相关信息并发至潜航器。潜航器被动接收水声通信数据,并对其进行综合处理,实现潜航器在水下隐蔽工作模式下对自身位置的实时修正,提高潜航器导航定位精度,具备较强的工程可实现性。
