The comparison of networks with different orders strongly depends on the stability analysis of graph features in evolving systems. In this paper, we rigorously investigate the stability of the weighted spectral distribution（i.e., a spectral graph feature） as the network order increases. First, we use deterministic scale-free networks generated by a pseudo treelike model to derive the precise formula of the spectral feature, and then analyze the stability of the spectral feature based on the precise formula. Except for the scale-free feature, the pseudo tree-like model exhibits the hierarchical and small-world structures of complex networks. The stability analysis is useful for the classification of networks with different orders and the similarity analysis of networks that may belong to the same evolving system.

作者： GAO E, WANG Zhi-sen (CIMS Institute, Hefei university of technology, Hefei 2.0009,{2.)

Manufacturing systems are in a dynamically changing e nvironment with uncertainty. Management of complexity, changes and disturbances is one of the key issues of production. The traditional hierarchical control of CIM systems limits the agility and the flexibility of the shop floor control sys tems and makes the reconfiguration and maintenance of shop floor control systems need high cost and much time. So new architectures are required to meet these c hallenges for the shop floor control systems. Recent fundamental research in distributed artificial intelligence and related applied research in intelligent manufacturing systems have shown that the Multi -Agent based system is one of the most promising methods. In a multi-agent man ufacturing system, the agents react to the information acquired from environment and communicate with other agents to co-operate to solve the global problem. I n this paper, a framework of reconfigurable shop floor control system based on m ulti-agent is presented. The concept of dynamic and logical manufacturing cell is proposed to organize manufacturing resources to achieve the ability of re configuration in dynamic shop floor environment. The framework is composed of three levels. First, the level of shop floor comp rises order agent, resource management agent, product management agent and t ask agent. Second, the level of dynamical cells consists of production agents an d control agents. Finally, the resource agents, such as AGV agents and machine a gents, belong to the equipment level. The control architecture in the framework is different from hierarchical control. It is hybrids of hierarchical and hetera rchical control architecture. The Contract Net protocol and its bidding mechanism are suitable and efficient t o implement the dynamic and logical manufacturing cells. Based on the Contract N et Model, dynamic negotiation during the process of forming the dynamic and logi cal manufacturing cells is analyzed in the paper. In this pape

Near-Space SAR:A Revolutionary Microwave Remote Sensing Miss...

2.07 Asian and Pacific Conference on Synthetic Aperture Radar(APSAR 2.07)

Inspired by the recent advances in near-space defined as the region between 2.km and 100km,this paper proposed the concept of near-space SAR. To the author’s knowledge,this is the first time that the near-space SAR is being proposed for microwave remote sensing missions. By placing the SAR’s transmitter /receiver in the near-space platforms,many functions that are currently performed with the satellites or airplanes could be performed much more cheaply and with much greater operational unity. These advantages make near-space SAR attractive for a variety of remote sensing missions. In this paper,the potential and challenges of the near-space SAR,compared to current spaceborne SAR and airborne SAR,were detailed. Various near-space SAR configurations are introduced,and their potential for different applications such as passive imaging,high-resolution and wide-swath imaging,and inverse SAR imaging were investigated. It is shown that,the use of near-space SAR can lead to the solutions that are previously thought to be out of reach for remote sensing scientists and customers.
