k-NN classification of handwritten characters via accelerated GAT correlation

This paper addresses the problem of reinforcing the ability of the k-NN classification of handwritten characters via distortion-tolerant template matching techniques with a limited quantity of data. We compare three kinds of matching techniques: the conventional simple correlation, the tangent distance, and the global affine transformation (GAT) correlation. Although the k-NN classification method is straightforward and powerful, it consumes a lot of time. Therefore, to reduce the computational cost of matching in k-NN classification, we propose accelerating the GAT correlation method by reformulating its computational model and adopting efficient lookup tables. Recognition experiments performed on the IPTP CDROM1B handwritten numerical database show that the matching techniques of the simple correlation, the tangent distance, and the accelerated GAT correlation achieved recognition rates of 97.07%, 97.50%, and 98.70%, respectively. The computation time ratios of the tangent distance and the accelerated GAT correlation to the simple correlation are 26.3 and 36.5 to 1.0, respectively.     

关于软件对字符编码方式误判的研究

针对目前字符编码方式众多的现状,应用软件如何更好的判断文件编码属于何种字符集,并将其正确的解码成为不容忽视的问题。针对Windows记事本不能正常显示"联通"二字的Bug进行分析,利用Winhex软件解析文件获得16进制编码,根据得到的编码分析误判原因,通过注释记事本IsTextUTF8函数对分析得到的误判原因进行证实,进一步找到了更多Windows记事本无法正常显示的汉字。

浅析中国本土戏曲角色与动画角色的融合

20世纪申后期,中国有很多经典的极富艺术魅力的动画角色一直印在我们的脑海中。像美猴王、葫芦娃、九色鹿、神笔马良、阿凡提等,角色造型风格各异。让人印象深刻。而如今大量动画作品在风格上跟风日美的痕迹,国产动画一定程度上失去了自己原有的民族性风格。进入新世纪。动画创作者开始尝试一些新的艺术手段来创作动画．而中国的传统戏曲具有独特的东方审美价值和艺术魅力,时值今日,动画工作者们一直都在尝试使用各种各样的艺术方式来进行动画创作。中国的戏曲文化博大精深。我们生活在这样一个文化氛围中。创作出具有本土文化特色的戏曲动画和塑造中国戏曲动画角色是万众期待的。     

服装设计的误区

通过对服装院校和企业进行田野式调查。归纳梳理出服装专业院校和企业存在的典型问题,认为当下服装教学的方法和内容中缺少自身的专业性。仍有沿用普通美术教学和与其他工业产品设计教育同质化的现象;服装企业里设计方法值得探讨,规范的程式化在有利于企业管理的同时也限制了服装设计的创新发展。设计者需以人为本。以美为据。设计同技术紧密结合才能避免踏入服装设计的误区。     

刺绣艺术中人物绣的艺术语言探析

人物绣在我国刺绣艺术中占有重要地位,根据所用的针法技艺和艺术特征,人物绣大致可归纳为写真人物绣、写意人物绣和装饰人物绣三种类型,写真人物绣以真实人物为绣制对象,追求逼真传神,刺绣语言鲜活生动;表意人物绣重在传达作者意象,注重人物动作及与环境关系的塑造,刺绣语言精致细腻;装饰人物绣富有装饰性和夸张的艺术效果,刺绣语言多元丰富。     

Effectiveness of cardenolides as feeding deterrents toPeromyscus mice

I compared the feeding responses of five species ofPeromyscus mice (aztecus, polionotus, melanotis, leucopus, andmaniculatus) to three bitter-tasting cardenolides (ouabain, digoxin, and digitoxin) that differ greatly in lipophilic character.Peromyscus, like other muroid rodents, are unusual in that they can ingest relatively large amounts of cardenolides without adverse physiologic effects. In experiment 1, I determined avoidance thresholds for the three cardenolides with 48 hr, two-choice tests. Mice exhibited large interspecific differences in avoidance threshold, and the interspecific ranking of the thresholds (maniculatus=leucopus >melanotis >polionotus >aztecus) was the same for each of the cardenolides. In experiment 2, I reevaluated the avoidance thresholds, but this time monitored the pattern of intake (i.e., bout lengths) during initial feeding encounters with cardenolidelaced diets. For each cardenolide, mice were subjected to three tests. In test 1, they received a control diet; in test 2, a diet containing the cardenolide at a concentration 1 log, unit below the avoidance threshold (as determined in experiment 1); and in test 3, a diet containing the cardenolide at the avoidance threshold concentration. Results were similar across all species and cardenolide types: Bout lengths in tests 1 and 2 were statistically equal, whereas those in test 3 were significantly shorter than those in test 1. The rapid rejection of cardenolide-laced diets in test 3 is consistent with a preingestive (i.e., gustatory) mechanism underlying the avoidance thresholds. I conclude (1) thatPeromyscus species differ substantially in taste sensitivity to cardenolides and that these differences may influence each species' respective ability to eat cardenolide-laced insects; and (2) that a species' relative taste sensitivity to one cardenolide predicts its sensitivity to other cardenolides.

银川市近49a来降雨变化特征分析

根据银川市4个气象站(银川站、永宁站、贺兰站、灵武站)近49 a(1960—2008年)的实测降雨资料,运用统计学理论、回归分析、Mann-Kendall非参数检验、克里金插值等方法进行研究,依据有关统计量的计算结果,分析了银川市近49 a来降雨量的时空变化特征.研究结果表明:银川市年内降雨量分配不均,夏季降雨量最大,占全年降雨量的56.83%~58.32%,冬季最小,仅占全年降雨量的1.93%~2.07%;年际以及年代际降雨量变化大,多年平均降雨量为186.7 mm,且以20世纪60年代降雨量最大,90年代降雨量最小.经Mann-Kendall非参数检验和一元线性回归分析,发现银川市降雨量呈现逐年减小的趋势,Mann-Kendall非参数检验趋势系数β为-0.18 mm/a,线性回归倾向率为-5.386 mm/(10 a).银川市降雨量还存在空间分布不均的特点,灵武市降雨量最大,减小的趋势最小;贺兰县降雨量最小,减小的趋势最大.
