Generalized Hamming Distance

Many problems in information retrieval and related fields depend on a reliable measure of the distance or similarity between objects that, most frequently, are represented as vectors. This paper considers vectors of bits. Such data structures implement entities as diverse as bitmaps that indicate the occurrences of terms and bitstrings indicating the presence of edges in images. For such applications, a popular distance measure is the Hamming distance. The value of the Hamming distance for information retrieval applications is limited by the fact that it counts only exact matches, whereas in information retrieval, corresponding bits that are close by can still be considered to be almost identical. We define a Generalized Hamming distance that extends the Hamming concept to give partial credit for near misses, and suggest a dynamic programming algorithm that permits it to be computed efficiently. We envision many uses for such a measure. In this paper we define and prove some basic properties of the Generalized Hamming distance, and illustrate its use in the area of object recognition. We evaluate our implementation in a series of experiments, using autonomous robots to test the measure's effectiveness in relating similar bitstrings.

Inter-ethnic preferences and ethnic hierarchies in the former soviet union

One-thousand two-hundred and ninety university students from twenty-seven ethnic?national groups across six locations in the former Soviet Union (Novopolotsk in Byelorussia, Kharkov in the Ukraine, Moscow and Nizniy Novgorod in Russia, Ufa in the Bashkir Autonomous Republic and Ulan-Ude in the Buryat Autonomous Republic) participated in 1991–1992 in a survey investigating the existence of ingroup preference in inter-ethnic contact, ingroup consensus on an ethnic hierarchy of outgroups and the measure of intergroup consensus on an ethnic hierarchy among the ethnic?national groups in each location. Hypotheses about ingroup preference, ethnic hierarchies and consensus were derived from realistic group conflict theory, social identity theory and from the assumption that outgroup preferences reflect considerations of the status effects of intergroup contact. It appeared that the last type of hypothesis could explain most of the results.     

男子l500m跑时身体各环节输出功的初步研究

运动高速摄影和跑台气体代谢法对男子中长跑运动员进行了研究。通过测定运动员1500m跑步过程中身体各环节输出功,发现运动员身体各环节输出功的比例关系为;摆动腿占比例最大,其次是支撑腿,上肢和躯干的输出功的比例相当,头部所占比例很小。运动员跑步过程中,环节内和环节之间存在能量转换,且环节之间能量转换是主要的。

地表模型上的最短路径算法研究

本文提出了一种基于空间三角网格表示的地表模型上的最短路径算法,该算法利用离散点的空间信息计算得到起点到周围邻接点的最短距离,然后利用逐步向外层边界扩展的方法扩大起点的邻接点范围,直到起点的邻接点中包含终点,此过程可求得s0到t0的最短路径上的关键点,然后求取无原始边连接的两个关键点之间的精确路径点。

优秀划艇运动员500m划拉桨技术与效果的研究

通过二维摄像解析优秀男子划艇运动员500m划过程中桨频、单桨桨力以及桨幅等动力学指标,研究运动员全程划技术特点和体能特点,研究结果表明:500m划过程中,桨频、单桨桨力以及艇速的变化基本一致,表现出起航时高桨频,中途由高桨幅代替桨频维持艇速,而在冲刺阶段是以高桨频和高桨幅维持冲刺效果的特征。但是运动员在途中划阶段,由于耐酸能力的下降,导致抓水不牢、晃桨的现象。
