阐述了在土地勘测定界测量中,为了提高工作效率,减少在生产中出现的错误,利用VB2005结合.NET API对AutoCAD进行了二次开发。在土地分类标注文字中,把土地类别和面积分别加入到文字的扩展数据中,然后在面积统计中再提取文字中的扩展数据进行计算并输出至表格,实现了土地利用分类的标注和面积统计的自动化。     

Exploiting the relationships among several binary classifiers via data transformation

The structural resemblance among several existing classifiers has motivated us to investigate their underlying relationships. By exploring into the mapping solutions of these classifiers, we found that they can be linked by simple feature data scaling. In other words, the key to these relationships lies upon how the replica of feature data are being scaled. This finding leads us directly to an exploration of novel classifiers beyond existing settings. Based on an extensive empirical evaluation, we show that the proposed formulation facilitates a tuning capability beyond existing settings for classifier generalization.     

Positive direct-mask stereolithography with multiple-layer exposure: layered fabrication with stair step reduction

In this paper, we explain a new stereolithography involving the separate use of liquid photoinitiator and a base resin (photopolymer resin without photoinitiator). First, the base resin is supplied as a layer, and then a mask pattern is drawn onto the surface with photoinitiator by inkjet printing. When the surface is exposed to a UV lamp, only the pattern drawn with the photoinitiator is cured. In this process, the photoinitiator acts as a positive mask. Also, the idea of multiple-layer exposure, which may enable stair step reduction and fabrication time reduction, is introduced. The proposed idea and method are implemented in an experimental stereolithography system and some experiments are conducted using the system. As a result, the effectiveness and feasibility of the idea and method are confirmed.     

Normal horizontal working area: the concept of inner boundary

A model was developed to determine the inner boundary of the normal horizontal working area based on the concept that the elbow and forearm-hand should move on the table surface while describing the area. The proposed model was applied to determine the normal horizontal working areas for the 5th percentile female and 95th percentile male. It was shown that the conventional models that had disregarded the concept of the inner boundary overestimated the area on the average by 26%. The proposed model is more realistic and accurate than the conventional models.

实验演算型住宅区地块容积率指标校核方法探索

虽然目前控制性详细规划中容积率等指标的核算有多种手段,但很少有基于实验的演算型定量研究。针对不同大小的基地,均可通过实验,推算日照标准约束下的容积率等指标,作为规划决策的重要依据。从当前日照标准约束角度,提出运用空间极限容积率校核的实验方法,通过计算机实验进行核算。提出了基于＂九宫格＂的计算方法,经过少量人工干预,由计算机生成指标对应的空间形态,以使控制性详细规划指标的确定更加科学、理性。实验表明,如果日照标准约束条件不变,容积率并不是可以随着住宅高度的增加而无限增加。如果需保证一定的日照资源质量,住宅高度和容积率存在增长极限。

风景区及其边缘城镇统筹发展研究——以重庆统景为例

立足资源、面向市场、强化差异性竞争成为中国西部城镇重要发展途径.风景区边缘城镇由于毗邻稀缺的风景名胜资源的区位优势,迫切希望依托风景区带动地方全面发展,事实上却存在开发与保护冲突、景镇建设脱节的现象,其核心矛盾在于景区与城镇定位不明、资源配置不利、产业发展脱节.基于可持续发展理念提出景镇统筹发展思路,其核心包括生态环境保护优先、产业经济统筹发展、空间景观整体塑造、社会生活和谐共荣.最后以重庆统景规划为例,构建以空间、风貌、旅游、地产四大板块为基础的景镇统筹发展整体框架,实现生态安全保障、经济高度发展、三大效益高度统一的发展目标.
