The Evaluation of Site Selection of Housing Industrialization Base Based on the Multi-level Grey Approach [PDF]
, 2017 住宅产业化基地的选址优劣对住宅产业化的健康发展起到关键性作用。产业化基地选址受到多方面指标影响,是一项极为复杂的系统工程。为了解决住宅产业化基地选址决策的指标不够客观、全面的问题,基于国内外住宅产业化基地发展的背景,从产业基础、社会政治、区域交通、经济环境、自然条件等方面构建住宅产业化基地选址评价指标体系。利用多层次灰色评价方法,以厦门市选址为例,用综合量化评价模型对备选方案进行考核,为不同选址方案评价提供可行实用的方法,有助于其他城市住宅产业化基地选址的决策提供参考。A The site ...

Zhejiang Daxue xuebao. Lixue ban, 2022 共振隧穿二极管（RTD）可编程逻辑门是一种由单双稳态转换逻辑单元（MOBILE）及正、负输入分支组成的阈值逻辑电路。基于二进制神经元模型中的三层网络结构，提出了基于RTD可编程逻辑门的n变量函数实现算法。按照汉明距离由大到小的顺序，搜索最优输入向量，用定理1或定理2方法产生隐层函数，通过变换次数，确定输入向量的真假及隐层函数的权重。由于定义了最优输入向量及变换次数，提高了算法的准确性；又由于采用了定理2方法，令设计的电路更简单。
