当今产品创意设计已由B2C(Business-to-Customer)向C2B(Customer-to-Business)转型,消费者参与度提升成为了企业的增长点。消费者参与有利于提高其参与感和对品牌的认可度,并能辅助企业人员完成创意探索、迭代过程。但当前消费者群体参与不够深入,且其碎片化创意元素无法有效捕捉利用。针对该问题,提出了一种融合消费者群体创造的产品创意设计方法,旨在促进消费者群体持续参与到产品创意设计过程中,辅助企业人员灵活捕捉并运用群体多元灵感来优化设计方案。首先,分析了群体创造在创意设计过程中的应用,建立了融合消费者群体创造的产品创意设计过程模型;然后运用文本挖掘和基于粗数的TOPSIS方法,研究了基于群体灵感的创意元素量化与识别方法以及基于群体评价的创意方案推演与优化方法,并在此基础上开发了融合消费者群体创造的产品创意设计系统。以桌面加湿器的设计为例,验证了所述方法的可行性与有效性。结果表明,所提出的方法能够有效拓展企业人员创意探索空间,提高消费者群体参与感。

当前,全球气候变化推升了投资者对投资组合风险的日益关注,全社会绿色投资兴趣也愈发浓厚。本文采用时变条件模型来研究绿色基金在新兴经济体的业绩表现。结果显示,绿色基金在市场基准下,这些基准包括A股市值加权指数、沪深300指数和深圳证券社会责任指数,都比那些传统同类基金具有超额收益。然而,没有证据表明绿色基金在经济疲软时的表现也优于传统基金。此外,在分组回归中,绿色基金仅在A股市值加权指数这一基准下显示出超额收益。总的来说,本文的结果支持了使用条件模型来评估绿色基金表现的重要性。同时,中国的绿色基金在发展初期并没有表现出明显的经济业绩劣势,这与之前欧美市场的研究结果有很大不同。

A rapid, automated flaw segmentation method using morphological reconstruction to grade wood flooring

引用

Journal of Forestry Research 2014年第4期25卷 959-964页

作者： Yizhuo Zhang Sijia Liu Jun Cao Chao Li huiling yu Northeast Forestry University Zhejiang University

Region-Growing Algorithms （RGAs） are used to grade the quality of manufactured wood flooring. Traditional RGAs are hampered by prob- lems of long segmentation time and low inspection accuracy caused by neighborhood search. We used morphological reconstruction with the R com- ponent to construct a novel flaw segmentation method. We initially designed two template images for low and high thresholds, and these were used for seed optimization and inflation growth, respectively. Then the extraction of the flaw skeleton from the low threshold image was realized by applying the erosion termination rules. The seeds in the flaw skeleton were optimized by the pruning method. The geodesic inflection was applied by the high threshold template to realize rapid growth of the flaw area in the floor plate, and region filling and pruning operations were applied for margin optimization. Experi- ments were conducted on 512×512, 256×256 and 128×128 pixel sizes, re- spectively. The 256×256 pixel size proved superior in time-consumption at 0.06 s with accuracy of 100%. But with the region-growing method the same process took 0.22 s with accuracy of 70%. Compared with RGA, our pro- posed method can realize more accurate segmentation, and the speed and accuracy of segmentation can satisfy the requirements for on-line grading of wood flooring.
