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.

In this paper a novel linear regression model is proposed to mine related queries from query logs. Three types of association relationships between queries are identified and leveraged in our model, which include query session co-occurence, URL-clicked sharing and text similarity. Previous work directly applies part of these relations, which may be largely affected by the noise in query logs, such as the sparsity of click-through data, query-session segmentation errors and noisy clicks. In this work we propose linear regression analysis to identify effective features. In this way, we can effectively deal with the noise issue. The experiments demonstrate that the features identified with linear regression analysis are very effective. Moreover, the performance of our proposed linear regression model outperforms existing methods.

In this paper, we investigate an optimal ordering policy in a dual-supplier system with forecast update when considering supplierpsilas unreliable lead-time and minimum lot size. It is showed that the optimal order quantity and expected profit of unreliable lead-time are smaller than those without uncertainty. The upper limits of supplierspsila minimum lot size that the manufacturer can accept are decreasing in the possibility of delay. Moreover, the unreliable lead-time reduces the feasibility of dual-supplier system.

Price competition in electronic markets is intense, and how to obtain positive price premium becomes a hot issue. According to Economics of Information (EOI) theory, eTailers should hide more sensitive information increase search cost and consequently to decrease consumerspsila price sensitivity. In contrast, signal theory suggests that providing rich information is an effective signal for eTailers to enhance consumerspsila trust and purchase intention. This research combines the two competitive theories to explore how eTailerspsila information provision about their products influences consumerspsila cognition and productspsila price premium in electronic markets. The results indicate that providing more information can lead to higher price premium.

Based on the trialism of science, technology and engineering, its category and way of thinking of systems engineering is introspected. And the necessity and feasibility of establishing the results-oriented systems engineering (abbr. ROSE), which belongs to the engineering category, is put forward. The new being which ROSE creates is in the form of system, and the process is of elements-integrating and whole-emerging. Its three principles: the results-oriented principle, lean-system principle and meta-integration principle are described. Moreover, the logic process of ROSE, whose activity elements are classified to two levels of system cognition and system practice, are discussed. Finally, an empirical analysis on ROSE is presented.

With the advent of the knowledge-based economy, the enterprise's management philosophy advances with the times as the environment constantly changes. As market competition continues to intensify, marketing activities are enlarging and customer demand is increasingly growing and diversifying. More and more enterprises have empowered their own front-line salespeople. And managers in enterprises are more concerned with the issues which employees in enterprises suit to be empowered and which factors will influence employee empowerment readiness. This paper proposes the definition of front-line salespeople's empowerment readiness, analyzes influencing factors of front-line salespeople's empowerment readiness, discusses the effect mechanism of influencing factors of front-line salespeople's empowerment readiness, finally, and puts forward some suggestions to enhance front-line salespeople's empowerment readiness from the perspective of human resource management practice.
