基于多帧的帧同步检测

阐述了帧同步检测的实质，分析了利用大数判决和基于统计的多帧检测算法，并对上述算法进行了仿真。由仿真结果可以看出，多帧检测的性能显著提高，并且多帧检测信噪比的适用范围比单帧的宽。     

基于多线程的CABAC并行编码方法

CABAC(Context based Adaptive Binary Arithmetic Coding)是H.264/AVC主要档次以上配置中推荐采用的熵编码方法.相比其他的熵编码方法,CABAC能够节省编码码率,但其计算串行性强,不能较好适应片上多核环境.针对这一问题提出了基于多线程的CABAC并行编码方法.大量实验统计表明,该方法负载划分较为均衡,对序列熵编码的单独加速比最高可达1.78.

磨损身管下的杆式穿甲弹强度失效计算机模拟

针对某型105 mm钨合金超速脱壳穿甲弹在射击试验时出现的弹体强度失效现象,使用有限元分析软件对其强度进行了分析计算。计算分两种工况：正常状态下的弹体应力应变分布和磨损身管条件下的弹体应力应变分布。根据计算结果,证实了弹体强度失效是由于火炮身管过度磨损的原因所致。     

The Mexican War: frontier expansion and selective incursion

ABSTRACT

Mexico’s defeat in the war that (in the U.S.) takes the country’s name resulted as much from the strategic context created by unrealized nation-building that followed independence as it did from American tactical supremacy. Three centuries of Spanish empire did not translate into national military excellence due to the decades of revolutionary upheaval that followed the sudden decapitation occasioned by Napoleon’s ouster of the monarchy in Madrid. That the occupation which followed major combat provided salutary lessons learned in dealing with guerrillas rather than a Vietnam-like litany of quagmire eventuated from the conscious designs of military leadership steeped in the same Napoleonic dynamic that had produced our opponent. The United States wisely chose to leave issues of state-building and governance to the Mexicans themselves, while annexing the sparsely populated northern remnant of Spanish empire.

基于位置预测的靶场图像实时判读方法

在靶场经纬仪对目标实时跟踪测量时,会发生相机随机抖动的情况,引起目标在图像中大幅度运动。应对大幅度运动时,基于搜索窗口的跟踪方法容易丢失目标,而基于全图搜索的跟踪方法时效性差。针对以上问题,提出一种结合核相关滤波算法(Kernelized Correlation Filter, KCF)和目标位置预测的改进的跟踪学习检测算法(Tracking-Learning-Detection, TLD)跟踪框架。利用正交多项式最优线性滤波器及相机角度信息预测目标下一帧位置,在此区域利用KCF进行快速跟踪,可以提高跟踪的成功率和时效性,跟踪失败时再进行检测。仿真实验表明,最优线性滤波器能较准确预测目标位置,给KCF提供较准确的搜索位置,算法每帧耗时仅为1.1 ms,且定位精度优于TLD和KCF,能有效应对相机抖动的问题。靶场实际试验证明该方法可提高靶场自动判读水平,减少人工干预。

Vicarious warfare: The counterproductive consequences of modern American military practice

This article examines contemporary modes of American warfare. It posits the concept of “vicarious warfare” as a means of capturing prominent patterns in warfighting approaches. Although rooted in long-standing traditions of military practice, vicarious warfare is sufficiently novel as to be identifiable as a distinct phenomenon. The precise manifestation or combination of vicarious methods vary according to the specific circumstances and political contexts prevailing in different theaters. However, America’s general preference is to fight its wars by delegating tasks to proxies and limiting exposure of its own military to danger. Where U.S. forces are employed directly, this takes place largely in the shadows. Such approaches have clear attractions, offer undoubted tactical advantages, and permit successive administrations to maintain a persistent tempo of operations that evades rigorous democratic scrutiny. Yet, prominent cases and numerous studies suggest that vicarious warfare has a high potential to generate counterproductive effects and significant strategic harm.
