监控视频运动目标的频繁轨迹模式挖掘

运用数据挖掘的方式分析运动轨迹数据在目前可以说是一种尝试。基于传统数据挖掘方法Apriori的思想,提出了一种监控视频运动目标的频繁轨迹模式挖掘算法。首先以特征点表示连续的运动目标轨迹,然后设计了一种轨迹相似度测量机制,最后基于相似度测量获得的轨迹段频率,将Apriori挖掘算法应用到2D运动轨迹数据,从中发现频繁轨迹隐含的一些感兴趣模式。实际的和人工生成的轨迹数据实验表明了算法的正确有效性。

Inventory transshipment game with limited supply: Trap or treat

Inventory transshipment is generally shown to be beneficial to retailers by matching their excess demand with surplus inventory. We investigate an inventory transshipment game with two newsvendor-type retailers under limited total supply and check whether the retailers are better off than the case without transshipment. We derive the ordering strategies for the retailers and show that unlike the unlimited supply case, a pure Nash equilibrium only exists under certain conditions. Furthermore, contrary to the conventional wisdom, we show that inventory transshipment may not always benefit both retailers. Although one of the retailers is guaranteed to be better off, the other could be worse off. The decision criteria are then provided for the retailers to determine if they will benefit from the exercise of inventory transshipment. Numerical study indicates that the carefully chosen transshipment prices play an important role in keeping inventory transshipment beneficial to both retailers. Subsequently, a coordinating mechanism is designed for the retailers to negotiate transshipment prices that maximize the total profit of the two retailers while keeping each of them in a beneficial position.     

谐波平衡法数值模拟周期性非定常流动

谐波平衡法是目前非定常流动数值研究中颇受关注的频域计算方法,该方法计算效率高,特别是对于周期性非定常流动问题具有明显的计算优势。采用谐波平衡法数值模拟高超声速导弹标模模型在不同参数下的强迫俯仰振动,重建气动力/力矩系数迟滞曲线,将计算结果与时域方法相比较,详细考察谐波平衡法的计算精度、效率和内存需求,分析不同参数对谐波平衡法计算的影响。计算结果表明,谐波平衡法适用于中小振幅下的非定常流动计算,且计算时间基本不受减缩频率的影响,对于长周期低频问题,较时域方法有明显计算优势。     

Does military spending promote social welfare? A comparative analysis of the BRICS and G7 countries

Whether military spending is capable of promoting social welfare is currently a controversial issue. The aim of this paper is to investigate how military spending affects the input and output of social welfare (i.e. social welfare expenditures and social welfare index). A panel cointegration analysis and an impulse response function are conducted with multi-country panel data, over two time periods, 1998–2011 and 1993–2007. In addition, to extend a comparative analysis over different economies, BRICS (i.e. Brazil, Russia, India, China, South Africa) and G7 (i.e. the US, Japan, Germany, the UK, France, Italy, Canada) countries are selected as representatives of emerging economies and developed countries, respectively. The empirical results show that military spending enhances social welfare expenditures in developed countries, while the effect is ambiguous in emerging economies. Also, military spending is capable of promoting the social welfare index based on the FMOLS estimation. The comparative analyses indicate that unlike in the G7, the effect of the growth of military spending on the growth of social welfare expenditures is negative and shorter in the BRICS.
