基于模糊层次分析法的公共建筑综合效益评价研究

针对公共建筑效益评价研究现状,提出对于公共建筑的评价更应当注重包括经济、社会、环境效益的综合效益评价．为此,应用模糊综合评判方法构建了公共建筑综合效益评价模型,并以徐州市奥体中心项目为例进行了实证研究．研究表明：将模糊综合评判方法应用于公共建筑综合效益评价,其评价结果真实可靠,具有较强的实用性和良好的应用价值．     

公共建筑与住宅建筑非传统水源利用技术分析

对在公共建筑与住宅建筑中利用非传统水源的技术进行了比较和分析,着重研究了雨水、中水和海水利用技术,指出了各项技术的优缺点和适用条件。结果表明,采用雨水利用技术时,可以因地制宜采用与直接利用、渗透、调节等功能相关的技术组合;采用中水回用技术时,可采用有发展前景的膜生物反应器技术,也可采用生物接触氧化或混凝沉淀等技术;采用海水利用技术时,可根据各种技术特点选用多级闪蒸、低温多效、反渗透等技术,另外,用清洁能源淡化海水是海水淡化技术的发展方向。实践中选用非传统水源利用技术时,应综合各种因素,进行全面比较。

Examination of thermal comfort in a hospital using PMV-PPD model

In this study, the performance of air conditioning system and the level of thermal comfort are determined in a state hospital located in Kermanshah city in the west of Iran in winter and summer using the Predicted Mean Vote (PMV) model which has been presented by ISO-7730 (2005). The Predicted Mean Vote (PMV) and the Predicted Percentage Dissatisfied (PPD) indices were computed using the data acquired from the experimental measurements performed in the building. The results showed that the values of PMV in some parts of the building, both for men and women, are not within the standard acceptable range defined by ISO. It was found that the most thermal problems in winter occur in morning work shift, and the worst thermal conditions in summer occur in noon work shift. The t-test results revealed that there is no noticeable difference between the thermal conditions of some rooms and those of the surroundings.     

Open-loop and feedback-controlled mouse cursor movements in linear paths

Path length (A), path width (W) and movement direction (θ) are identified as the main factors affecting visually-controlled movement times in linear paths. Effects of A and W are well described by Drury's ( 1971 . Movements with lateral constraint. Ergonomics, l4 (2), 293-305.) model in which movement time is linearly related to the ratio of A/W. At low A/W values, departure from linearity has been identified but not investigated in detail. Data are presented for both open-loop and feedback-controlled movements in linear paths at 0, 60 and 150° movement directions. Movement amplitude and path width were varied over a wide range to determine the effects of A and (A/W) on movement time. Movements were found to be made ballistically or in open-loop mode when the ratio (A/W) was less than about 8 to 10 and the movement times were linearly related to √A for all angles of movement. Feedback-controlled movements followed Drury's law; ballistic movements had movement speed linear with √A. PRACTITIONER SUMMARY: Many tasks require manoeuvring equipment or devices through a path of limited width. These movements can be made with or without feedback control, depending on the path constraints. The conditions for the two forms of movement are determined in this research.

基于闭合等深线端点法提取河流深泓线方法的研究

利用闭合等深线法提取深泓线时需通过等深线的高程建立等深线树,但由于等深线中存在地形要素的交叉和覆盖及获得等深线高程值时的误差等原因,使得原本闭合的等深线形成了断开、合并、孤立的对象及高程信息的丢失,根据这种对象建立的等深线拓扑关系连接得出的深泓线无法正确反应实际深泓点的拓扑关系。针对存在断开、合并、孤立的等深线时的情况,提出了利用加权邻接矩阵法建立等深线多叉树的方法。实践证明使用此方法保证了利用闭合等深线法提取出的深泓点之间拓扑关系的正确连接。
