水电工程施工区水泥混凝土路面设计方法探讨

根据现行水电工程施工区水泥混凝土路面设计规范,以水泥混凝土面板疲劳强度作为控制指标,比较了两种设计方法的计算结果,发现按照《公路水泥混凝土路面设计规范》计算所得的水泥混凝土路面结构厚度较厚。通过分析这两种设计方法的差异,提出《厂矿道路设计规范》更适合用来指导水电工程施工区水泥混凝土路面的设计,同时也提出该规范还需进一步完善,以考虑最重轴载对施工区的极限破坏作用。     

基于总入流概念的鄱阳湖设计洪水计算

由于受到江河湖槽自然演变和人类活动的影响,鄱阳湖出湖控制站实测资料无法满足一致性和可靠性要求,再加上湖区水情复杂、观测资料匮乏,导致设计洪水计算面临较大困难。基于入库洪水理论,引入了总入流的计算方法,对于湖区各支流控制站和无控区间来水的流量过程,只考虑传播时间的叠加,避免了对各种自然、人为因素影响的定量计算,计算结果真实反映了洪水量级与时程分配过程,满足设计洪水计算规范要求。计算成果可为鄱阳湖区综合规划、水利枢纽设计提供依据。

Style synthesis and analysis of car designs for style quantification based on product appearance similarities

Understanding how similar design appears is a key element to understanding companies’ design strategies. However, it is difficult to evaluate companies’ design strategies with conventional style measurement methods since they only taxonomically measure whether a specific characteristic is included in a specific style. This study numerically measured car design similarities to synthesize and analyze car brand styles, thereupon discovering the design trends among car brands for strategic design positioning. This paper aims to find methods for quantifying style differences and identifying unique design elements of car designs among 23 automobile manufacturers based on design similarities of a large quantity of car designs (N = 119). To achieve this goal, a hybrid style quantification methodology – a mixture of Fourier decomposition, eye tracker, and shape grammar – was created to evaluate similarities, visual significance, and combinations of 19 car design elements. Fourier decomposition was incorporated to find the quantifiable values of design similarities of car design elements. Visual significance analysis was also conducted for each car design element through eye tracker to measure the importance of certain design elements for weighting factors. Then, each combination of design elements was compared with car design elements of other cars for similarity calculations. Finally, car design alternatives were synthesized, and transitions of design positioning were analyzed based on the similarity values weighed by the visual significance results. Using the suggested methods, alternate designs can be synthesized while preserving brands’ design styles, and design trends can be analyzed for strategic evaluation.     

Design ethnography in information systems

Until recently, most ethnographic research in information systems has been based on the traditional anthropological model of ethnography. In this traditional model of ethnography, one of the most important data‐gathering techniques is participant observation. The ethnographer observes and participates but does not actively seek to change the situation. In recent years, however, a new type of ethnographic research has emerged – one that can be called design ethnography. Design ethnography is where the researcher goes beyond observation and actively engages with people in the field. Our view is that design ethnography has much potential for research in information systems. It is a new form of engaged scholarship that bridges the gap between ethnographic research and design science research.
