Adaptive soft k-nearest-neighbour classifiers

A novel classifier is introduced to overcome the limitations of the k-NN classification systems. It estimates the posterior class probabilities using a local Parzen window estimation with the k-nearest-neighbour prototypes (in the Euclidean sense) to the pattern to classify. A learning algorithm is also presented to reduce the number of data points to store. Experimental results in two hand-written classification problems demonstrate the potential of the proposed classification system.

Tomcat应用系统乱码问题研究

由于Tomcat和Java对字符集的处理机制和中文编码有冲突,乱码是Tomcat应用系统开发人员经常遇到的问题。该文在论述字符集和字符编码以及java对字符编码的处理机制的基础上,探究了出现的乱码的原因并提出相应解决办法。     

文字设计艺术在电视节目包装中的应用

文字是电视节目包装中的重要元素之一,除了传达信息的基本功能之外,经常起到决定整体效果的关键作用。节目包装文字设计应突出本台文化和本土文化,文字的设计必须与节目相匹配,形成统一整体。     

古代汉字展示的视觉序列在日常生活中的发展

中国古代汉字的视觉序列是单行的从上到下、横列的从右到左。战国以后,文字的视觉序列便由此随着文字一起为更多的人所的认识及使用。围绕人们生活周围的视觉序列更是丰富多彩,如:招幌、商业印刷品、对联及园林匾额和楹联等等。     

苏北盆地洋心次凹泰一段上亚段储层特征分析

泰州组一段上亚段砂岩储层岩石类型主要为长石石英砂岩、长石岩屑砂岩、岩屑质长石砂岩和岩屑石英砂岩;储层孔隙度主要分布在7％～17.4％之间,渗透率主要分布在(0.17～125.1)×10-3μm2之间;储集空间主要类型为粒内溶孔、粒间溶孔和裂缝溶孔;根据物性分析和压汞资料,将泰州组一段上亚段储层划分为Ⅰ～Ⅳ四种类型.基于定量成岩作用的分析,认为压实作用、胶结作用是本区储层物性变差的主要原因,溶蚀作用则大大改善了储层物性.     

饱和软黄土的力学与工程性质分析

The effects of age,viewing distance,display type,font type,colour contrast and number of syllables on the legibility of Korean characters

This study evaluated the effects of age (20s and 60s), viewing distance (50 cm, 200 cm), display type (paper, monitor), font type (Gothic, Ming), colour contrast (black letters on white background, white letters on black background) and number of syllables (one, two) on the legibility of Korean characters by using the four legibility measures (minimum letter size for 100% correctness, maximum letter size for 0% correctness, minimum letter size for the least discomfort and maximum letter size for the most discomfort). Ten subjects in each age group read the four letters presented on a slide (letter size varied from 80 pt to 2 pt). Subjects also subjectively rated the reading discomfort of the letters on a 4-point scale (1 = no discomfort, 4 = most discomfort). According to the ANOVA procedure, age, viewing distance and font type significantly affected the four dependent variables (p < 0.05), while the main effect of colour contrast was not statistically significant for any measures. Two-syllable letters had smaller letters than one-syllable letters in the two correctness measures. The younger group could see letter sizes two times smaller than the old group could and the viewing distance of 50 cm showed letters about three times smaller than those at a 200 cm viewing distance. The Gothic fonts were smaller than the Ming fonts. Monitors were smaller than paper for correctness and maximum letter size for the most discomfort. From a comparison of the results for correctness and discomfort, people generally preferred larger letter sizes to those that they could read. The findings of this study may provide basic information for setting a global standard of letter size or font type to improve the legibility of characters written in Korean.

Statement of Relevance: Results obtained in this study will provide basic information and guidelines for setting standards of letter size and font type to improve the legibility of characters written in Korean. Also, the results might offer useful information for people who are working on design of visual displays.
