To analyzed the characteristic of the e-hub and the whole project life cycle. The e-HUB can support the lifecycle business process. Based on this, the paper established the e-HUB system model based on workflow. The model divides project collaboration into the five stages. The five stages are job solicitation, finding the right partner, planning the collaboration, executing the project, and partnership...
This paper improved the search manner of HFC (Hierarchical Fair Competition) model, and introduced an optimization method which was mixed with structure parameters based on genetic programming (GP). Meanwhile, some adaptive mechanisms were added to HFC model, and then generated three derived HFC models: static generational HFC model (SHFC) which added an opened topology search to the initial HFC model;...
Small and medium size enterprises (SMEs) are considered as the backbone of the manufacturing industry in China, and a breeding ground for business ideas for the knowledge-based economy. Flexible integration of resources and engineering collaboration of self-governed SMEs is expected to facilitate the strengthening of the competitive position of SMEs. This paper presents the "e-engineering enabled...
Simulated annealing algorithm (SA) is a random heuristic search method which is based on Monte Carlo's iterative solution .For its global optimization nature, robustness, versatility and parallelizability, SA was applied widely in various fields of design optimization. However, SA's evaluation ability was limited by insufficiency of its sustainability. This article improves SA by introducing a rank-based...
Conceptual innovation in mechanical engineering design has been extremely challenging compared to the wide applications of automated design systems in digital circuits. This paper presents an automated methodology for open-ended synthesis of mechanical vibration absorbers based on genetic programming and bond graphs. It is shown that our automated design system can automatically evolve passive vibration...
Small non-coding RNAs play important roles in regulating cell functions by controlling mRNA turnover and translational repression in eukaryotic cells. Here we isolated 162 endogenous small RNA molecules from Oryza sativa, which ranged from 16 to 35 nt in length. Further analysis indicated that they represented a diversity of small RNA molecules, including 17 microRNAs (miRNAs), 30 tiny non-coding...
