基于一步延时的航迹起始改进算法

针对现有多目标航迹起始算法工程实践性不强的特点,研究了一种基于一步延时的航迹起始算法,并在分析该算法的基础上,针对该算法计算量随目标数目增加而成指数增长的不足,对其算法进行了改进,提出了一种双重滤波的一步延时的航迹起始算法。仿真结果表明,该算法提高了航迹的正确起始概率,减少了计算量,具有较好的工程应用前景。     

Precision cyber weapon systems: An important component of a responsible national security strategy?

Given the advances made in conventional weapon capabilities, precision should by now be the accepted and expected norm in cyberspace as well. In this article I argue that developing precision cyber weapon systems, to be used during a lawful conflict, can be an important part of a responsible national security strategy to reduce the amount of violence and physical destruction in conflicts. I first describe a precision cyber weapon system in a military context. I then present three compelling rationales for the development of precision cyber weapon systems based on ethical, operational, and financial considerations. To support the position, I address several arguments that have been levied against their development. Thereafter I present several recommendations for a way ahead.     

生物柴油作化工溶剂的水解性能研究

由脂肪酸甲酯组成的生物柴油是一种替代传统苯类化工溶剂的理想替代物,但易水解的特点制约了其广泛应用。通过表面活性剂的复配技术,考察表面活性剂对生物柴油水解的影响。实验结果表明,生物柴油在碱性介质中易水解,温度升高水解加剧。而阳离子、非离子表面活性剂及其复配物具有很强的抑制生物柴油水解的能力。
