模糊方向神经网络在火箭发动机故障检测与分离中的应用

提出了一种模糊方向神经网络分类器,并应用于液体推进剂火箭发动机故障检测与分离。模糊方向神经网络采用模糊集表示发动机故障模式,模糊集是方向超体聚集形成的集合体,方向超体则由单位方向、夹角和两个半径确定。模糊方向神经网络能在一次循环学习中形成非线性方向边界。故障检测与分离的仿真研究表明：模糊方向神经网络的识别性能是比较优越的。

多自由度系统及结构非线性自由振动的摄动谐波平衡法

本文在谐波平衡法的基础上,引入摄动的思想,得出了解多自由度系统及结构的非线性自由振动的新方法。其解的形式为小参数和谐波的级数形式,因此,其解不会遗漏任何项,方程为线性的代数方程;利用线性变换,将系数矩阵变换为对角阵,一旦求出线性模态,就可得其解,比线性化迭代法优越得多。算例表明,本文方法对于小振幅有较高的精度,对于较大振幅其结果也是令人满意的。

Transformation of Military Ethics During the Zhou Dynasty in Ancient China

ABSTRACT

The transformation of the governance model from a rule of virtue to political realism in China has been a topic of great interest to scholars. In this study, I examine military culture during the Zhou Dynasty and investigate the changes in ethics based on factors such as cultural values, social customs, and political structure to understand the process by which moral values have changed as the governance model transformed from rule of virtue to political realism. I found that military ethics have changed from governance through the use of rituals during the Western Zhou Dynasty to what was called “deception makes an army” during the Eastern Zhou Dynasty.     

Killing with Culture: Anthropology’s Ethical Dilemma with War

ABSTRACT

This article highlights the difficulty of creating a code of ethics in anthropology, particularly one that appropriately addresses the nuanced nature of the military and the anthropologists who conduct research and disseminate information in the context of war. The article consults one of the most important books on this topic, George R. Lucas' Anthropologists in Arms (2009), along with several other relevant texts, and examines the ethical complexities and dilemmas American and European anthropologists faced during their involvement in both World Wars, as well as those faced during Vietnam and the more recent wars in Iraq and Afghanistan. The article also examines the military's recruitment of cultural experts, the methods used to culturally engage combatants, and the criticisms against social scientists who choose to work as so-called military anthropologists. The anthropologists in this article risked academic exile conducting what some consider an adulteration of academic principles. The article contributes to the discourse regarding unconventional warfare and the methods used by the armed forces to better understand the cultural nuances of people, and to highlight the need for the development of a better anthropological code of ethics that accounts for the challenges of war.
