GCr15轴承钢连铸坯冶金质量的分析

分析了结晶器电磁搅拌、钢水过热度和轧钢工艺对连铸GCr15轴承钢180方坯轧材中心疏松、碳偏析、碳化物液析等缺陷的影响，结果得出连铸时采用电磁搅拌和降低钢水过热度可减轻铸坯碳偏析，铸坯在1210℃均热60min可减轻甚至消除钢中碳化物液析。     

Software and systems engineering process capability in the South Australian defence industry

It is well recognised that that there is a correlation between process maturity in large organisations and project success. In response to this, a number of process models and standards have been developed for the large-project environment. The Australian defence industry, unlike many overseas countries, relies to a much greater extent on small and medium-sized enterprises to supply equipment and services. Hence, the question has arisen about the scalability of overseas concepts to the Australian defence industry situation. To address this question, a research project has been undertaken to identify the current baseline of process capability for the South Australian defence software and systems engineering industry. This paper presents findings from the research project, including a general characterisation of the industry process capability and a discussion of the common perceived strengths and challenges of organisations within the industry. The project’s objectives, research design and findings are then compared and contrasted with similar research activities conducted in different parts of the world. Finally, the paper draws conclusions based on the body of work presented and suggests areas for future research and development to address industry needs.     

On-line resources allocation for ATM networks with rerouting

This paper presents an application we developed for France Telecom R&D to solve a difficult real-life network problem. The problem takes place in an Asynchronous Transfer Mode (ATM) network administration context and consists in planning demands of connection over a period of 1 year. A new demand is accepted if both bandwidth and Quality of Service (QoS) requirements are satisfied. Demands are not known prior to the assignment and must be performed on-line according to their arrival. Moreover, the acceptance or the reject of a demand must be decided within a given time of 1 min.
