海岸带多源数据三维无缝拼接技术

为解决多源海陆数据中基准不一致、数据模型及格式不统一、同一地物表达上的差异等问题,设计了海陆数据的无缝拼接方案.利用坐标转换和垂直基准差拟合解决空间基准的不一致性,建立统一海部水深离散点和陆部等高线的多源数据无缝数字高程模型(DEM),基于点删除的不规则三角网(TIN)简化算法可实现海岸带模型的多尺度表达.实例分析表明,该方案可实现多源海陆数据的三维无缝拼接和多尺度表达.

流行装定价策略与价格模型的建立

利用产品生命周期理论对流行装定价策略进行研究,并以流行周期及其所处流行区段为基础构建流行装基准价格模型。通过考察品牌、销售场所、售后服务和市场竞争等因素对流行装价格的影响并探讨各因素权重取值方法,建立流行装市价模型。     

基于灰色前馈神经网络的流行色预测

提出结合灰色理论和前馈神经网络的流行色预测模型GLMBPNN(Gray Levenberg-Marquardt Back Propagation Neural Network),并利用Levenberg-Marquardt算法提高传统BP(Back Propagation)神经网络模型的学习速率.运用灰色理论学习历史数据的变化规律,对数据进行灰化处理,再对比目标值与BP网络的初始输出值,不断进行逆向反馈修正,训练完毕后通过仿真、白化处理得出流行色预测值.研究表明,GLMBPNN模型预测所得的流行值比灰色模型方法所得值的精度高,且比传统BP神经网络的收敛速度快.     

无缝钢管产品水压实验爆裂原因分析

对无缝钢管产品水压实验过程中发生的9例典型爆裂事故产生原因进行了宏观和微观综合分析.结果表明:引发钢管产品水压实验爆裂均与管体局部存在某种缺陷有关.连铸坯缺陷包括表面裂纹、表面存在保护渣和增碳、表面渗铜、中心偏析和内部夹杂物偏聚等;轧管缺陷包括表面划伤、壁厚不均和偏薄等;管加工缺陷包括表面淬火裂纹、热处理组织异常、屈服强度偏低、管端螺纹加工精度差等.针对分析结果,提出了改进措施.     

Predictive modeling of consumer color preference: Using retail data and merchandise images

The popularity of a fashion item depends on its color, shape, texture, and price. For different items (with all attributes identical except color) of a specific product, fashion retailers need to learn consumer color preference and decide their order quantities accordingly to match their products to consumer demand. This study aims to predict consumer color preference using the knowledge learned from merchandise images, historical retail data, and fashion trends. In our work, merchandise images are analyzed to extract color features, and the retail data of a sportswear retailer are used to reveal consumer choices among items with various colors. Choice behavior is described by a multinomial logit model, whose utility function captures the relationship between color features and popularity. Both linear functions and neural networks are applied to represent the utility function, and their out-of-sample prediction performances are compared. According to the out-of-sample performance test, our model shows reasonable predictive power and can outperform order decisions made by fashion buyers.     

论时尚色彩在包装设计中的应用

Practice of Italian Trend Book in China

In the past five years, trendy information spread via imported renowned fashion magazines appeared unable to satisfy the industrial needs. Trend books from Milan and Paris have been introduced to big cities in China through official Chinese national agencies, and have gradually drawn more attention within the Chinese fashion industry. Chinese fashion businesses and their designers have difficulties in using the trend book. The main reason is that they don＇t understand the whole structure re of the book, the true meaning of the instruction and the way to use the book. Most companies are not using the book in the correct way. However, if no one realizes this is not the right key to the real fashion design world, an incorrect design logic and abnormal production chain will appear in China which will directly produce an unhealthy impact to the country. It＇s only possible to catch up and grasp the real European trend with Europe at the same time when the trend books are used correctly.
