Theoretical Analysis of the Factors Affecting Splice Loss During Fabric Spreading

Material utilization is mainly concerned by industrialpractitioners since it contributes to minimize the totalproduction costs for garment manufacturing. Apart fromthe marker loss, splice loss (the fabric loss during thejoining of different fabric rolls) is one of the primarycauses of fabric loss, but it has not been considered spe-cifically in the past literatures. The amount of splice lossduring fabric spreading is governed by various factors in-cluding the marker length, the number of fabric rolls,and the number of splicing intervals for laying-up. Inour study, these three effects on splice loss during fabricspreading were computed and analysed.     

Evidence and explanation in Cicero's On Divination

In this paper, I examine Cicero's oft-neglected De Divinatione, a dialogue investigating the legitimacy of the practice of divination. First, I offer a novel analysis of the main arguments for divination given by Quintus, highlighting the fact that he employs two logically distinct argument forms. Next, I turn to the first of the main arguments against divination given by Marcus. Here I show, with the help of modern probabilistic tools, that Marcus' skeptical response is far from the decisive, proto-naturalistic assault on superstition that it is sometimes portrayed to be. Then, I offer an extended analysis of the second of the main arguments against divination given by Marcus. Inspired by Marcus' second main argument, I formulate, explicate, and defend a substantive principle of scientific methodology that I call the “Ciceronian Causal-Nomological Requirement” (CCR). Roughly, this principle states that causal knowledge is essential for relying on correlations in predictive inference. Although I go on to argue that Marcus' application of the CCR in his debate with Quintus is dialectically inadequate, I conclude that De Divinatione deserves its place in Cicero's philosophical corpus, and that ultimately, its significance for the history and philosophy of science ought to be recognized.

卫星遥感资料在湛江港风暴潮漫滩计算中的应用

为解决风暴潮漫滩计算缺乏潮间带地形和漫滩资料的困难,提出了基于卫星遥感资料的风暴潮漫滩计算方法:选取不同潮位的高分辨率遥感图像,提取淹水线,将遥感淹水线近似作为等高程线估算潮间带地形,作各遥感淹水线对应时刻的漫滩数值模拟,订正估算的地形,得到潮间带地形资料;将遥感淹水线推算的潮间带地形用于风暴潮模式,作风暴潮漫滩计算,并将遥感淹水线作为漫滩资料,检验计算结果.利用该方法,采用卫星遥感资料作了9615号台风在湛江港风暴潮漫滩的计算和检验.结果表明,数值模拟的漫滩面积与遥感图像误差平均为11.5%,采用该方法进行风暴潮过程的漫滩计算具有实用价值.
