针对模糊自整定控制器参数寻优能力差的不足,研究了采用自适应交叉概率与变异概率的遗传算法,提出了用这种自适应遗传算法改善模糊自整定控制器性能的方法。对采用自适应遗传算法的模糊自整定控制器与一般的模糊自适应控制器作了仿真对比研究,说明了前者的优越性。     

Holmes’ front: constructing a new face of battle for America’s Civil War

ABSTRACT

In his seminal study of the changing nature of warfare between Agincourt and the Somme, military historian John Keegan proposed that future historians might consider combatants’ emotions in their assessments of the impact and nature of conflict. Recent years have witnessed the emergence of the history of emotions as an analytical approach, but rarely, if ever, is this directed toward the study of military history, far less the history of insurgencies and counter-insurgencies. This paper examines America’s civil war (1861–1865) as a case study of the ways in which an emotional history approach might illuminate not the physical experiences of but rather the immediate and longer-term reactions to counter-insurgency conflict through a focus on one specific individual, the future Supreme Court Justice Oliver Wendell Holmes, Jr. It proposes that Holmes, whilst not a man of the ranks, nevertheless can reveal the wider ramifications of civil war and its emotional impact, both individually and culturally. As a relatively limited internecine war, one not fought by professional armies but by volunteer forces, America’s civil war highlights the ways in which the soldier’s response points us toward the kind of emotional revolution that has, to date, mainly been located within the European nations.
