Colombia: Changing strategy amidst the struggle

From 1965 to the present, Colombia has been confronted by the insurgency of the Revolutionary Armed Forces of Colombia (FARC). The threat reached a new level in 1996 with the advent of mobile warfare, whereby large units sought to neutralize the military in an effort to seize power and institute a Marxist-Leninist regime. Unlike Vietnam, what followed was a regaining of the strategic initiative by the government and a decimation of the insurgent threat. This was accomplished with US assistance but from first to last was driven by Colombian leadership and strategy. The strategy which led to this signal change, ‘Democratic Security’, unfolded under the leadership of President Álvaro Uribe. It was a civil–military partnership, which sought to expand the writ of Colombian democracy to all elements of society. Securing the population provided the shield behind which economic, social, and political life could occur as driven by the will of the people. It was the agreement upon legitimacy as the strategic goal and reform as the route to that goal which allowed the Colombians and the Americans to work so well together.     

Born violent: Armed political parties and non-state governance in Lebanon's civil war

We know little of the internal governing practices of non-state actors once in control of territory. Some territories have witnessed the establishment of new institutions of public goods remarkably similar to state institutions. This article compares four armed political parties governing territory during the Lebanese civil war. These non-state violent actors established complex political and economic institutions and administrative structures. Despite the wide range of ideologies and identities of these actors, they all converged in their institutional priorities, although not in their capacities or the particular ways of achieving those priorities. Data from interviews and the actions of the armed political parties suggest a combination of ideology and desire for control is causal in generating public institutions, partly attributable to the high degree of citizen activism marking the Lebanese case.     

Lessons learnt? Cultural transfer and revolutionary wars, 1775–1831

Did participants in small wars in the period 1775–1831 learn from previous or contemporary examples? While this is difficult to prove for participants who left no written records, there is considerable evidence in existing publications by practitioners that they did indeed draw out lessons from recent insurgencies, either from their own experience or from events elsewhere which they studied from afar, especially the Spanish Guerrilla, which had already become legendary. Most authors showed an interest in how to stage insurgencies rather than in how to quell them. Even then, transfer did not come in a package of tactics-cum-values, but in each case in different configurations.     

使用局部色调映射匹配异源图像

色调映射是一种适用于亮度和对比度变化的快速图像匹配方法。由于异源图像间存在复杂的灰度变换关系,直接采用色调映射方法进行匹配的成功率通常难以满足应用需求。为了提高匹配成功率,本文提出基于子区弱切片变换的局部色调映射异源图像匹配方法。首先将实时图划分为不重叠的子区,对每个子区进行直方图均衡化和弱切片变换,通过局部色调映射计算子区与基准图的距离系数图。融合全部距离系数图得到图像匹配结果。实验结果表明,该方法匹配成功率高于现有的色调映射方法,且计算时间仅略高于现有方法,优于异源图像匹配中常用的互信息方法。

直升机攻潜策略是反潜战中值得研究的一个问题。研究攻潜策略实质是确定最优投雷点,即直升机的最优接近航向和投雷时刻。本文研究的结果是:如果目标作等速直线运动,则直升机的最优接近策略为平行接近法。     

用局部对比度信息改善图像质量

在图像的摄取和传输中,图像经常降质。为了改善图像质量,将信息熵的概念与图像的局部对比度信息相结合,提出了一种基于熵概念的非线性噪声的滤除方法,并进一步利用局部统计信息对图像进行增强。分别对模拟图像以及红外图像进行了试验,并与中值滤波、Lee滤波、Frost滤波等经典噪声滤波方法进行比较,实验结果验证了该方法的有效性。
