Communication: A simple full range analytical potential for H<sub>2</sub> b<sup>3</sup>Σ<sup>+</sup><sub>u</sub>, H - He <sup>2</sup>Σ<sup>+</sup>, and He<sub>2</sub> <sup>1</sup>Σ<sup>+</sup><sub>g</sub>
No full textThe Tang-Toennies potential for the weakly interacting systems H2 b3Σ+u, H–He 2Σ+, and He2 1Σ+g is extended down to the united atom limit of vanishing internuclear distance. A simple analytic expression connects the united atom limiting potential with the Tang-Toennies potential in the well region. The new potential model is compared with the most recent ab initio calculations for all three systems. The agreement is better than 20% (H2 and He2) or comparable with the differences in the available ab initio calculations (H–He) over six orders of magnitude corresponding to the entire range of internuclear distances

An improvement on "Integrated production strategy and reuse scenario : a CoFAQ model and case study of mail server system development"
No full textThe authors (Tang et al. (2013) [1] developed a CoFAQ model to formulate a solution for the problem of production strategy decision and reuse scenario selection for a software product family. In the previous research, we stated that the CoFAQ model was a 0-1 mixed integer nonlinear program, where only a local optimal solution might be found. In a recent study, we found that the CoFAQ could be transformed into a 0-1 mixed integer linear programming model. By solving the model, a global optimal solution can be obtained. In this paper, we present the improved formulation and the optimal solution for the case study.Department of Industrial and Systems Engineerin

State and Slavery in the Tang Empire
No full textSlavery had a profound influence on societies that do not meet Finley’s definition of “slave societies,” such as Tang dynasty China (618-907). Legal institutions and moral discourse in Tang China emphasizes two broad categories, the free (Chinese liang 良; Japanese ryō; Korean yang, literally “good”) and the unfree debased (Ch. jian 賤; Jap. sen; K. chon, literally “debased”). This project examines the broader category of unfree people in Tang China with a special focus on the cross-regional slave trade and captivity among the Tang and its neighboring states. Comparing the practices of slave trade in the capital regions and three borderlands (the Korean peninsula, the Lingnan region in South China, and Dunhuang and Turfan in central Asia), it explains how the Tang state decided whom to enslave and why from 600 to 900. Drawing from an array of primary sources such as The Tang Code, the writings of Tang elites, epitaphs of the enslaved individuals, as well as documents excavated from modern-day Xinjiang, this research reconstructs the lived experience of enslaved individuals in middle-period China. The Tang Dynasty witnessed an important shift in attitudes towards slavery during the Tang dynasty. Before the 750s, there was a near-universal acceptance of the enslavement of foreigners and border peoples. By the end of the dynasty, many—including some of the most famous Tang-dynasty literati, such as Liu Zongyuan 柳宗元 and Han Yu 韩愈—began to argue against slavery. They did so not through a radical denial of the existing social hierarchy, but by acknowledging some assimilated indigenes in Lingnan and commoners from Silla were no different from Chinese imperial subjects. And they believed the Tang state owed those assimilated people protection from enslavement

Body length 1.3–1.4 mm (n= 3). Gall (Figs 82–84). Galls are monolocular, red pimples on midribs or lateral veins of young leaves; on occasion the galls can also develop on male catkins. In some cases the gall development disrupts the sprouting of leaves and the galls form a tuft on a bud. The gall is 1.0– 1.7 mm in width and 1.6–3.3 mm in length. Biology. Only the sexual generation is known which induces galls on Q. globosa. The gall development coincides with sprouting from mid- to late-March. Adults emerged under laboratory conditions immediately after the galls had been collected in the field and transferred to the laboratory. Distribution. Currently known only from Taiwan: Renai Township, Nantou County, and Heping District, Taichung City. The host-plant Q. globosa is endemic to Taiwan, thus C. globosus might be also endemic to Taiwan.Published as part of Tang, Chang-Ti, Sinclair, Frazer, Hearn, Jack, Yang, Man-Miao, Stone, Graham N., Nicholls, James A., Schwéger, Szabina & Melika, George, 2016, Eight new species of Cycloneuroterus Melika & Tang gallwasps from Taiwan and mainland China (Hymenoptera: Cynipidae: Cynipini), pp. 451-488 in Zootaxa 4088 (4) on pages 470-473, DOI: 10.11646/zootaxa.4088.4.1, http://zenodo.org/record/25966
Heuristics for the economic lot scheduling problem with returns. [In special section on problems and models of inventories selected papers of the fourteenth International symposium on inventories]
Full text linkWe study the multi-item economic lot scheduling problem (ELSP) with two sources of production: manufacturing of new items and remanufacturing of returned items. Manufacturing and remanufacturing operations are performed on the same production line. Tang and Teunter [2006. Economic lot scheduling problem with returns. Production and Operations Management 15 (4), 488–497.] recently presented a complex algorithm for this problem that determines the optimal solution within the class of policies with a common cycle time and a single (re)manufacturing lot for each item in each cycle. This algorithm is rather complex and time consuming, combining a large MIP formulation with a search procedure, and may therefore not always be practical. In this paper, we deal with this type of problems and propose simple heuristics that are very fast and can be applied in a spreadsheet package. A large numerical study shows that the heuristics provide close to optimal solutions
