计算机工程与应用 2003年第30期39卷 28-30页

作者：彭晓明丁明跃周成平张天序华中科技大学图像识别与人工智能研究所图像信息处理与智能控制教育部重点实验室武汉430074

论文针对灰度相关模板匹配跟踪算法的局限性,提出了一种基于信息融合的运动目标跟踪算法。该方法同时利用图象中的灰度信息和边缘信息,从而克服了只依靠单一信息源的不足。实验结果表明,该方法明显提高了跟踪性能。

For the problem that the truck' cab has an excessive vibration in usual speeds, the vibration testing platform was built, and its vibration characteristics were studied. Though effective testing the signal from the cab and some mount positions in usual different speeds, the signals' frequency components and vibration systems' transmission characteristics were analyzed, and the their correlations were studied, the modal characteristics of cab and frame system were calculated and tested, the results that the most main excitation source is the wheel, and transmission characteristics of the spring and frame system are worse are Acquired. Some proposals reducing the excitation power by doing the dynamic balance to tires, deceasing the stiffness of springs and increasing the stiffness of frame system are carried out on the real truck, and in the usual speeds the road experiments' effects of objective and subjective are great, the achievements are met of factory, which also proves the ideas of studying and solving the truck vibration are effective and could be valuable reference for the same engineering problems.

Chaos particle swarm optimization (CPSO) can not guarantee the population multiplicity and the optimized ergodicity,because its algorithm parameters are still random numbers in *** paper proposes a new adaptive chaos embedded particle swarm optimization (ACEPSO) algorithm that uses chaotic maps to substitute random numbers of the classical PSO algorithm so as to make use of the properties of stochastic and ergodicity in chaotic search and introduces an adaptive inertia weight factor for each particle to adjust its inertia weight factor adaptively in response to its fitness,which can overcome the drawbacks of CPSO algorithm that is easily trapped in local *** experiments with complex and Multi-dimensional functions demonstrate that ACEPSO outperforms the original CPSO in the global searching ability and convergence rate.

网络已成为当今世界重要的信息载体,但是网络信息良莠不齐,对人们的生活造成了很多负面影响,因此,如何正确识别网络中的敏感话题,是当前网络舆情分析与监管的重要任务之一。本文以识别网络论坛中的敏感话题为目标,基于网络论坛文本在结构和表达上表现出的篇幅短、结构不完整、文字口语化等特性,将该类文本表示成基于向量空间模型的文本矩阵,并根据网络敏感话题具有先验知识和态度倾向性等特点,提出了基于倾向性词典的特征提取方法,可有效提高网络敏感话题识别的正确率,最后通过实验验证了这一改进的有效性,证实了本文的研究价值。
