This study uses multiple regression to investigate the effects of Land and building use on popuLation, Land price, and passengers. Initialty, we abstract annuat data on Land and buildings usage within a radius of 0 m-400 m for railway stations and 400 m-800 m for subway stations in Fukuoka, Japan by using the GIS. We then analyze the relationships between 13 factors of rand use and 8 factors of building usage, as well as the related poputation, Land price, and passengers using the quantitative expression method. Using several categories of land use and building usage as explanatory variables, we anatyze the degree to which the selected categories affect population, Land price, and passengers by using the muttiple regression method. This research can aid the further development of land and buitding usage in the future.

This study focused on the structure and the platform of the road space of historic districts. We analyzed the road networks of 16 historic districts in Japan from the perspectives of circularity, accessibility and indirection based on graph theory. By calculatin8 and comparing the indexes of each road network （NW1 and NW2） forms, we quantitatively describe the effects of the main prefectural roads （more than 4 m in width） and narrow streets （less than 4 m in width） on the spatial characteristics. And it turned out that we could divided the 16 objective historic districts into 4 types. Moreover, we qualitatively studied the characteristics of each type of historic districts based on their development background and the structure of road network.

Many cities organize cultural festivals to promote their distinctiveness, boost the local economy, and enhance quality of life. However, urban spaces are packed with visitors on festival days, thus affecting accessibility to pedestrian spaces. This research examined visitor satisfaction with accessibility to pedestrian spaces during special events such as festivals. We particularly focused on the Hakata Dontaku festival, which is celebrated in Fukuoka, Japan. We studied three main elements that affect pedestrian satisfaction and perceived accessibility through walking, namely, safety, mobility, and amenities. We first analyzed previous studies and employed analytical hierarchy process to setup indicators for satisfaction measurement. Second, we determined visitor satisfaction through a survey questionnaire, which was conducted during the Hakata Dontaku festival. Third, we assessed the normality of the data set that was obtained from the questionnaire. Finally, we applied structural equation modeling. Results showed that the proposed model was a good fit, as indicated by the goodness of fit test, and the majority of indicators loaded significant values that supported their constructs. Satisfaction with amenities was found to be the most statistically significant variable that influences visitors＇ perceived accessibility during the Hukata Dontaku festival

This special issue is one of the outputs of the 9th Interna- tional Symposium on City Planning and Environment Man- agement in Asian Countries held on 11-13 January in 2014 at Horuto Hall OITA, Japan. Currently, Asia accounts for 40% of world＇s urban population, which will increase to 56% by 2030. Urbanization is one of the biggest issues in Asian countries. On the other hand, in the economic development countries such as Japan and South Korea, the aging problem has also emerged. In order to achieve the sustainable urban society, it is increasingly necessary to find urban design innovations and appropriate research methods and tools.

为了获得飞机蒙皮自动钻铆中锪孔的孔径尺寸和锪窝的深度信息,本团队搭建了一套基于双目视觉的检测系统。在立体匹配环节,该检测系统以十字激光在钻铆孔上的交点作为匹配基准,构建左右图像边界点的投影映射模型,同时采用基于模拟退火算法的多层感知器模型对脱离映射关系的边界点进行二次修正优化,解决了边界区域因亮暗变化差异微小导致的误匹配问题,保证了边界点的匹配精度;在双目视觉的三维重建中,以拟合空间曲线的方式建立钻铆孔的空间圆锥模型,从而得到钻铆孔的内孔孔径和锪窝深度。实验结果表明,基于十字激光匹配方法生成的点云数据的法向绝对偏差小于0.018 mm,而孔径测量误差以及锪窝深度测量误差均在0.04 mm以内,有效提高了钻铆孔的检测精度。

传统的文本分类方法假设训练集与测试集中的特征词服从相同的概率分布,但在实际应用中,以上假设存在偏差,会影响到最终的分类结果。针对这一情况,本文采用迁移学习,通过计算特征词的迁移量对训练集中向量空间模型进行修正,最终使训练集与测试集中特征词的分布概率趋于一致。将提出的方法应用于中文垃圾邮件过滤与中、英文网页分类中,在CHI统计特征选择基础上进行特征迁移,实验结果表明新方法可以有效消除特征词分布的差异性,使文本分类的各项指标明显提高。

为了实现飞机蒙皮锪孔的高质量检测,提出一种结构光锪孔参数检测方法。该方法基于正交投影建立空间圆锥参数模型,并采用傅立叶曲线和power函数优化模型,有效地避免了实际工程中锪孔点云缺失带来的检测精度下降问题。首先对原始点云进行降噪处理,根据边缘点集中分布在一侧的特点提取了上下边缘并拟合成平面,其次根据正交投影后锥角在XOZ坐标平面或YOZ坐标平面满足傅立叶变换的特点,建立了精确的空间圆锥数学模型,进而获取评价锪孔质量的参数。另外,考虑到被检锪孔本身轴线与坐标平面Z轴会存在偏差,即拟合的空间圆锥轴线与Z轴存在偏差,基于傅立叶变换曲线得出的极值差与法向偏差角之间的关系,提出了法向偏差角的优化数学模型,进一步保证了质量参数的准确性。实验验证了该算法具有更高的精度和更好的抗噪声性能。
