新型无毒引发剂在卫生级聚氯乙烯糊树脂生产中的应用研究

针对卫生级糊树脂的开发要求,采用新型无毒过氧化物引发剂(Luperox 701)替代现有的偶氮引发剂(ABVN)进行糊树脂生产的工业试验。试验表明各替代条件下的聚合过程都较平稳,胶乳性能和产品糊树脂性能均达到企业质量标准,其生产过程和产品性能与原工艺相近。由于Luperox 701的活性较ABVN略低,需进一步优化配方,缩短聚合时间,以提高装置生产能力。

Learning effectiveness of applying automated music composition software in the high grades of elementary school

The paper is mainly to explore the automated music composition experiences for the students in the high grades of elementary school who are unfamiliar with the professional music theory. The proposed Automated Composition for Music Education (ACME) software was developed to help the students to compose the rhythm and melody themselves, while chord configuration and arrangement are automatically generated. Subsequently, sixth-year students of a non-experimental school were recruited to use the software for the completion of its development. Analysis of learning effectiveness at the reaction level, analysis of learning-level learning effectiveness, correlation analysis of the reaction- and learning-levels learning effectiveness has been performed with a significant result. The correlations between each component of learning effectiveness at the reaction and learning levels were also found. Finally the students in the experimental group using the ACME teaching materials showed a better learning effectiveness at both reaction level and learning level, than those of the students in the comparison group.     

Conceptual basics and tools to assess the multi hazard vulnerability of existing buildings

The European Macroseismic Scale 1998 – (EMS 98) is an instrument for the natural hazard of earthquakes, which allows the explanation of observed differences in the behaviour of the prevailing construction types by introducing and implementing vulnerability classes. The EMS 98 enables also the identification of purely empirically justified ranges of scatter. The basic methodology is also applicable to other natural hazards such as flood, tsunami and wind. This permits the development of a unified methodology for the consideration of building vulnerability in the sense of a multi‐hazard approach. For the first time, a vulnerability‐oriented instrument is available to evaluate a building stock for different natural hazards according to criteria that have been standardised in terms of engineering. The multi‐hazard vulnerability with its possible scatters is examined and visualized on real building inventories. With the concept of ”LEGOisation“ the existing buildings, a novel approach is presented to allow the sub‐structuring of buildings into storeys (including roof, basement and floors) to further development of the classification towards specific damage characteristics and local vulnerability. A still to be developed ”Conceptual Simulation Tool“ is described as an outlook. This uses the tools and methods developed to simulate damage and losses as a result of various natural hazards and their sequences.     

Dynamic programming and mixed integer programming based algorithms for the online glass cutting problem with defects and production targets

In flat glass manufacturing, glass products of various dimensions are cut from a glass ribbon that runs continuously on a conveyor belt. Placement of glass products on the glass ribbon is restricted by the defects of varying severity located on the ribbon as well as the quality grades of the products to be cut. In addition to cutting products, a common practice is to remove defective parts of the glass ribbon as scrap glass. As the glass ribbon moves continuously, cutting decisions need to be made within seconds, which makes this online problem very challenging. A simplifying assumption is to limit scrap cuts to those made immediately behind a defect (a cut-behind-fault or CBF). We propose an online algorithm for the glass cutting problem that solves a series of static cutting problems over a rolling horizon. We solve the static problem using two methods: a dynamic programming algorithm (DP) that utilises the CBF assumption and a mixed integer programming (MIP) formulation with no CBF restriction. While both methods improve the process yield substantially, the results indicate that MIP significantly outperforms DP, which suggests that the computational benefit of the CBF assumption comes at a cost of inferior solution quality.     

一种考虑等级语义关联的证据推理决策方法

现有证据推理方法以证据理论为信息融合规则,并未考虑评估等级在语义上的关联关系,导致以正交求和方式进行信息融合时出现信息流失现象。从评估等级的语义和级别出发,提出一种基于等级语义关联的证据分类融合方法。基于新的证据融合模型,构建一个基于改进证据推理方法的多属性决策框架,并给出决策模型和决策流程。最后,通过一个案例演示了新方法的决策过程,并通过比较新旧方法在案例上的应用分析了新方法的特点。
