通信时延对无人作战飞机NWL轰炸精度影响研究

无人作战飞机具有飞行器与指挥平台"空地分离"的技术特征,源自飞行员的战术决策指令须通过战术数据链传输给飞机,该特性在空地轰炸模式下将对系统作战效能产生一定的影响。建立了面向无人作战飞机的空地一体化机翼非水平(NWL,Non-Wing-Level)轰炸仿真模型,通过Monte-Carlo仿真表明脱靶量与数据链时延之间存在线性关系,采用Kalman滤波可以克服时延对脱靶量的影响,并提高命中精度。     

Performance analysis of the cultural and creative industry: a network‐based approach

The cultural and creative industries (CCIs) in Taiwan have gradually contributed to the national economy under the impetus of government policies. We employ a two‐stage data envelopment analysis model with an additive efficiency decomposition approach to measure the profitability and marketability of 22 Taiwanese cultural and creative companies. Furthermore, we employ the network‐based ranking approach to identify benchmark inputs/outputs, and the strengths and weakness of each company. Our empirical results show that the profitability of the cultural and creative companies is better than their marketability. Companies in the industries of publishing, creative life, popular music, and cultural content averagely perform better than those in the other three types of CCIs in terms of profitability. Companies in the creative life industry are on average more efficient than those in the other five types of CCIs in terms of marketability. The profitability/marketability matrix of cultural and creative companies is also presented.

Applying Lanchester's linear law to model the Ardennes campaign

In modern warfare, many believe the decisive factor in winning a battle is seizing the right moment to shift from defense to attack, or vice versa. This paper attempts to bring that perspective to Lanchester's differential equations of warfare, and continues the application of Lanchester's linear law to the analysis of the World War II battle of Ardennes, as reported in earlier issues of Naval Research Logistics by Bracken and by Fricker. A new variable, shift time, accounting for the timing of the shift between defense and attack is explicitly included in our version of the model, and it helps obtain improved goodness of fit to historical data. © 2001 John Wiley & Sons, Inc.

简评西方哲学的"人本质"思想

人的本质问题是西方哲学史中的一个重要问题,许多哲学家都对这个问题提出了自己的看法,这些看法都有一定的根据,但或者是错误的,或者是片面的,只有马克思和恩格斯作了全面的科学的回答.本文对这些看法作了简要的清理与评论,对于如何理解马克思主义的观点有一定的参考意义.
