Geographical opportunistic dissemination scheme in an urban setting has a lot of potential applications range from daily services like advertising and local weather forecast to safety-related services such as fire/accident warning. These applications share several unique characteristics such as location-based address of nodes and maintaining in an area for a specific time. However, all existing solutions fail to take into account these characteristics.In this paper, we propose a novel opportunistic information dissemination scheme via metropolitan bus networks. The scheme firstly makes use of geographical information like street map and bus route to convert information dissemination within a specific area to opportunistic multicast to non-overlapped road segments. A probabilistic routing protocol based on closest distance predictability is presented to multicast the message to its multiple destination road segments and then disseminate to roadside users. We use dissemination ratio and number of replicas as metrics to evaluate the performance of the scheme. And the simulation results show that the proposed dissemination scheme achieves high dissemination ratio when the number of buses is enough with an acceptable number of replicas (network overhead).

In this paper the idea of active security situation sensing is introduced. The active security situation sensor which is different from the traditional sensor such as firewall or IDS, can capture attack intention and predict attack trends before attack occurs to productive system. The design and implementation of our A3S are described, and the whole system of security situational awareness is also simply introduced.

Optimization is a classical problem in graph theory, and lots of researchers are working on the complexity of complex networks. We visualize and analyze some countriespsila national highway networks with Pajek and Ucinet, and find that they share several universal topological properties: tending to choose short edges, average degree is smaller than 4, small clustering coefficient and large diameter, and the degree distribution can be expressed in a general formula. All of above characteristics attribute to 2-dimension of the spatial network. Then we modify the optimization model from the economic viewpoint and use genetic algorithm to optimize the networks, which is proved useful and effective.

In order to enforce the sensing performance of mobile sensor network (MSN), an enhanced self-deployment (ESD) algorithm is proposed in this paper. By designing the virtual repulsive force between nodes, the movement equation and the virtual attracting-field in the sensing area, the problems of the network partition and coverage holes which are aroused by conventional potential-field-based deployment approach is solved. Simulation results show that ESD algorithm exhibits excellent performance and expands the generalization of MSN greatly.

Firstly this paper highlights the importance of organizational decision knowledge system. Then decision makerpsilas learning behaviors and the mechanism of knowledge intervention have been analyzed and introduced. Thirdly this paper discusses the concept of total decision support (TDS) for improving the effect of decision making and compares total decision support and traditional decision support system (DSS) from several aspects. Based on the above analysis we put forward the research framework of total decision support and point out the future work.

A diameter-age model was developed for dahurian larch (Larix gmelinii. Rupr.) in northeastern China based on Chapman-Richards growth model using nonlinear mixed-effects modeling approach. The methods of model development include which parameters should be considered to be random and which should be purely fixed, as well as procedures for determining autoregressive correlation structures. Model performance was evaluated utilizing information criterion statistics (AIC, BIC, and LRT). The Chapman-Richards model with two random parameters showed the best performance. The inclusion of autoregressive models (AR(p), MA(q), ARMA(p,q)) in the mixed-effects model resulted in a significant improvement of model fitting statistics.

Currently, there exist different trust models in peer-to-peer application. Each model has an abundance of trust information about trust and reputation attributes which are needed for establishing trust between peers. These trust models canpsilat be easily interoperable due to no approach for integrating in a semantic way the trust information from different models. Integrating trust information in a semantic way is a significant step towards the realization of trust models interoperability in an open system such as Web where resource providers and users are often strangers to one another and universal and correct expressiveness of trust information will be crucial. Therefore, this paper proposes an ontology-based approach for integrating trust information models. Additionally, it is also useful for simplifying security policies specification and protecting sensitive information.

In the process of risk investment decision-making, real option which is one of the key issues in the research of finance engineering is very important to enforce flexibility of management decision. As for appraising methodology, the real option approach is used. However, The investment circumstance is always vague. That is to say, the information we need is incomplete. The uncertainty influences the real option valuation by all appearances. In this paper we take into account the uncertainty of the up and down jump factors of underling assets, which are estimated by triangular fuzzy numbers. While pricing for the real option, we use the binomial model and the risk-neutral valuation approach, and then derive the risk-neutral probability intervals. As a result, we obtain a decision-making model for risk investment projects under vague circumstance. It is beneficial for the evaluation of risk-investment and useful for avoiding the mistaken investment decision-making.Finality, we provide a corresponding example analysis.
