Technical Notes ：STUDIES ON THE VALUE OF SECONDARY MARKET TO THE SUPPLY CHAIN

This paper investigates the impact of a secondary market, where retailers can buy and sell excessinventories, on the supply chain. We develop a two-period model with a single manufacturer and tworetailers. At the beginning of the first period the retailers order and receive products from themanufacturer, but at the beginning of the second period, they can trade surplus products betweenthemselves in the secondary market. We investigate the impact of the correlated dependence ofretailers' demand on both the quantity effect and the allocation effect under the secondary market.Lastly,we study potential strategies for the manufacturer to increase sales with the existence of thesecondary market.     

FROM MANUFACTURING SCHEDULING TO SUPPLY CHAIN COORDINATION：THE CONTROL OF COMPLEXITY AND UNCERTAINTY

With time-based competition and rapid technology advancements, effective manufacturingscheduling and supply chain coordination are critical to quickly respond to changing marketconditions. These problems, however, are difficult in view of inherent complexity and variousuncertainties involved. Based on a series of results by the authors, decomposition and coordination byusing Lagrangian relaxation is identified in this paper as an effective way to control complexity anduncertainty.A manufacturing scheduling problem is first formulated within the job shop context withuncertain order arrivals, processing times, due dates, and part priorities as a separable optimizationproblem. A solution methodology that combines Lagrangian relaxation, stochastic dynamicprogramming, and heuristics is developed. Method improvements to effectively solve large problemsare also highlighted. To extend manufacturing scheduling within a factory to coordinate autonomicmembers across chains of suppliers, a decentralized supply chai

活血陪元法治疗对艾滋病患者T淋巴细胞功能的影响

目的研究活血培元法治疗对艾滋病患者T淋巴细胞功能的影响.方法筛选已经开始服用抗逆转录病毒药物的HIV/AIDS成年患者24例,且病毒载量＜500 copies/ml,随机分成两组,一组加用东研Ⅰ号颗粒(中成药)和安慰剂对照,观察患者0、12、24w后的临床症状体征、T淋巴细胞亚群、血清HIV病毒载量以及细胞因子(IL-2、IL-4、IL-10、INF-γ)的变化.结果分析中药组与对照组0、12、24w后症状体征积分两组存在明显差异(P＜0.05);T细胞亚群CD4+T细胞绝对计数也有明显差异(P＜0.05);细胞因子两组均无明显差异(P＞0.05).两组病毒载量始终均为＜500 copies/ml.结论中药活血陪元法(东研Ⅰ号颗粒)能有效改善HIV/AIDS患者的临床症状及体征,提高患者的CD4+T细胞绝对计数,协助抗逆转录病毒药物控制病毒载量,但未发现对患者T细胞功能的部分细胞因子有显著影响.     

氮肥对结缕草种子生产影响的研究

通过研究不同氮肥用量对二年生结缕草种子产量的影响,初步结果表明:结缕草的草高随着施氮量的增加而增高,草高与施氮量间存在极显著的正线性关系.当氮肥用量为8g/m2时,结缕草单位面积穗数、穗粒数最多,结缕草种子产量也最高,达到761kg/hm2,发芽率为96%.

PDE-Based Medial Axis Extraction and Shape Manipulation of Arbitrary Meshes

Shape skeletonization （i.e., medial axis extraction） is powerful in many visual computing applications, such as pattern recognition, object segmentation, registration, and animation. In this paper, the authors expand the use of diffusion equations combined with distance field information to approximate medial axes of arbitrary 3D differential properties. It offers an alternative solids represented by polygonal meshes based on their but natural way for medial axis extraction for commonly used 3D polygonal models. By solving the PDE along time axis, this system can not only quickly extract diffusion-based medial axes of input meshes, but also allow users to visualize the extraction process at each time step. In addition, the proposed model provides users a set of manipulation toolkits to sculpt extracted medial axes, then use diffusion-based techniques to recover corresponding deformed shapes according to the original input datasets. This skeleton-based shape manipulation offers a fast and easy way for animation and deformation of complicated mesh objects.

Systemic Intervention in a University Department: Reflections on Arrested Action Research

This paper reflects on my experience as an insider researcher attempting to use critical systems ideas and practices to promote quality improvement in a university engineering department. Reflection is a key part of learning. This paper is intended to contribute to critically, self-reflective learning for the community of systems practitioners. These reflections on my questions about participation, ethics, politics of process, and the choices and actions resulting from them may help others to formulate their own. The complexity of systems practice places substantial demands on the researcher, particularly in the case of insider, practitioner research. Nevertheless, the exploration of critical systems approaches to critique boundaries and structure ‘problems’ in the core aspects of higher education in locally meaningful ways should continue. While demanding, it still can work to promote learning about authentic quality.
