运用ECO开发基于UML的工作流系统

运用UML进行建模并运用MDA方法生成系统代码已成为当前工作流系统设计开发的一大发展趋势。经过多年发展的ECO技术为.Net环境下运用MDA方法开发基于UML的稳定高效的软件系统提供了很好支持,而ECOⅢ则通过支持UML动态建模,使得ECO具备了开发基于UML工作流系统的能力。通过示例介绍了运用ECO进行工作流开发的一般流程,着重展现运用ECO开发工作流系统的可行性和高效性。     

一种基于DCT和SVM的人脸识别新方法

文中提出了一种新的人脸识别方法,该方法采用DCT提取人脸特征,并采用SVM对该特征进行分类识别。基于该方法,对ORL人脸库进行分类识别,仅用28个特征平均识别率达到97.4%。仿真结果表明,该方法显著地降低了特征维数和计算复杂度,明显提高了特征的可辨别能力,而且,SVM可以有效地提高分类器的分类和推广能力。

复合材料层合结构层向理论及应用进展

层向理论是由Reddy提出来的一种用于精确分析复合材料层合结构的三维板壳分析理论.由于不引入任何的变形和应力假设条件,因此相较于传统的等效单层板理论,层向理论在分析大厚度复合材料层合板壳结构的静动态响应及其局部层间效应时具有较大的优势.系统地综述了层向理论近年来的研究进展、数值解法及其应用情况.具体包括:层向理论的基本...     

Guerrilla warfare in Katanga: the Sanga rebellion of the 1890s and its suppression

ABSTRACT

This article discusses the origins and development of the Sanga insurgency of the 1890s with a view to demonstrating that, contrary to commonly held stereotypes, pre-colonial warfare was neither simple nor unchanging. Its tactics, it is argued here, repay the sort of close analysis commonly reserved for other typologies and theatres of war. The Yeke, against whose exploitative system of rule the Sanga and their allies rose up in 1891, survived the onslaught by entering into a strategic alliance with Lofoi, a newly established station of the Congo Free State, and its limited contingent of regular Force Publique troops. An in-depth examination of the joint Yeke-Force Publique counterinsurgency campaign leads to the conclusion that the novelty of the ‘small wars’ that accompanied the Scramble for Africa should not be overstated. In southern Katanga and, by implication, elsewhere, these confrontations were shaped by processes of mutual borrowing in which African military practices and even political aims were not necessarily subordinate to European ones.     

Chemical-weapon use in Syria: atrocities,attribution, and accountability

ABSTRACT

International efforts to hold the government of President Bashar al-Assad accountable for the use of chemical weapons in the Syrian Civil War have entered a new phase. For the first time, the Organisation for the Prohibition of Chemical Weapons (OPCW), the international organization responsible for implementing the 1993 Chemical Weapons Convention, has been empowered to identify the perpetrators of chemical attacks in Syria. The Investigation and Identification Team (IIT), which was formed to conduct the OPCW’s new attribution mission, has announced its intention to investigate and identify the perpetrators of nine chemical attacks in Syria, including the April 7, 2018, attack in Douma. This article reviews recent efforts to attribute chemical attacks in Syria, describes what we know about the nine incidents to be investigated, summarizes what is known about the Syrian government officials, military commanders, and chemical-warfare scientists suspected of being responsible for these attacks, discusses what to expect during the next phase of the attribution process, and offers insights into how the international community can move beyond attribution to accountability. Accountability is necessary to provide justice for victims and to prevent future incidents by demonstrating that perpetrators of chemical attacks will be identified and punished.
