控制性详细规划的法制化与制定的逻辑

回顾控规的起源与发展概况,从法的实质与城市发展四个"I"的特征重新认识法定规划的作用。美国区划制定的内在逻辑揭示了规划法制化的基本依据。我国控制性详细规划处于法定规划体系中,其法制化的矛盾既源自法定规划体系的关系,又源于规划自身制定的过程。文章认为,回归法的本质与城市发展的实质,结合中国的社会政治环境探索我国法定规划体系是当前迫切的任务之一。     

Extending the Q system's prediction of support in tunnels employing fuzzy logic and extra parameters

Rock mass classifications predict support measures according to expert rules by rating rock mass and taking into account the span of the opening. A similar procedure is adopted, in this work, and computerized using statistics and fuzzy logic. Fuzzy expert systems are trained with data of previously constructed underground openings. Using subtractive clustering the systems have the intelligence to pick up the relations between input and output and define the rules that represent the system's behavior automatically. These systems are found to predict support to be used more successfully than the Q system. With the introduction of extra input variables, which are important in numerical analysis, such as depth and intact rock strength, an extended fuzzy system is developed. This system is suggested for preliminary use as it is able to predict support even better.

演化硬件的应用与发展

演化硬件将可编程逻辑器件的结构位串当作染色体,通过演化算法进行搜索,找出符合要求的染色体,把它配置可编程逻辑器件,得到的即是要设计的硬件电路.其应用采用遗传算法,包括电路进化设计和在线自适应与容错两个主要方向.演化硬件则面临硬件平台的选择及演化硬件的可升级性两方面的挑战.     

A fuzzy approach for the earned value management

The Earned Value technique is a crucial technique in analyzing and controlling the performance of a project which allows a more accurate measurement of both the performance and the progress of a project. This paper presents a new fuzzy-based earned value model with the advantage of developing and analyzing the earned value indices, and the time and the cost estimates at completion under uncertainty. As the uncertainty is inherent in real-life activities, the developed model is very useful in evaluating the progress of a project where uncertainty arises. A small example illustrates how the new model can be implemented in reality.     

Andalusia,Spain: An Assessment of Coastal Scenery

The 1101 km length of the Andalusian coast (Spain) was assessed for coastal scenery at 45 specific locations. Selected areas covered resort (3), urban (19), village (8), rural (10) and remote (5) bathing areas. Scenery was analyzed for physical and human parameters via 26 selected parameters. These parameters were obtained by interviews of >500 people on European beaches. Each parameter was assessed via a one-to-five-point attribute scale, which essentially ranged from presence/absence or poor quality (1), to excellent/outstanding (5). Results were subsequently weighted by interviewing >600 bathing area users (not all 26 parameters have equal weight) and subjected to fuzzy logic mathematics in order to reduce recorder subjectivity. High weighted averages for attributes 4 and 5 (excellent/outstanding) reflected high scenic quality, vice versa for attributes 1 and 2. Sites were classified into five classes ranging from Class 1 sites having top grade scenery to Class 5, poor scenery. Seven sites each were found in Classes 1 and 2; 10 sites each in Classes 3 and 5; 11 sites in Class 4. The finest coastal scenery was found in remote areas whilst urban areas scored mainly as Class 3 or 4. Three out of the ten rural sites had Class 3 and 4 values assigned them whereas the rest scored as Class 1 and 2; village sites invariably had scores within Class 3 and 4. Of the three resort sites investigated, one scored as a Class 1 site, the others as Class 3.

基于面阵CCD的高灵敏度微型光谱仪的设计与实现

面阵CCD具有灵敏度高、动态范围大的优点,适用于荧光测量、DNA测序、拉曼光谱分析和低光度检测,因此,研制基于面阵CCD的高灵敏度微型光纤光谱仪具有重要的实际价值。光学系统采用了优化后的交叉非对称型Czerny-Turner结构,并获得了1 nm的光学分辨率。结合DC-DC和LDO的设计方法,通过USB供电实现了6路电压输出的复杂电源系统设计; 通过Verilog HDL完成了CCD驱动时序设计; 采用Altera公司的EPM7064芯片实现了驱动信号输出。CCD输出的视频信号经双相关采样的高速16位AD芯片AD9826转换后存储在独立的静态RAM中,使得数据的采集和读取分离。所设计与实现的微型高灵敏度光纤光谱仪的灵敏度是通常基于线阵CCD的微型光谱仪的11倍左右,动态范围20000:1,信噪比达到500:1,很大程度地提高了微型光纤光谱仪的性能。
