Abstract: This paper investigates knowledge work process and its characteristics based on human-information system (H-IS) interaction using concurrent protocol and observation methods. It is found that the ability of knowledge workers to obtain information feedback from information system (IS) is a key factor affecting the information processing speed of knowledge work. Therefore, an enhanced H-IS collaboration reduces the total time of knowledge work and improves knowledge work efficiency. In addition, when IS is applied to semi-structured knowledge work, H-IS interaction has insignificant influence on the quality of the task.

Abstract: The present work contributes to the field of border and coastal surveillance sound target classification. A new feature extraction method is proposed based on the optimum wavelet packet decomposition (OWPD). According to the frequency characteristic of border and coastal surveillance sound signals, each signal is decomposed by selective multi-scale wavelet packet decomposition (WPD) and the OWPD tree is obtained. From their high dimension OWPD coefficients, we build the meaningful and compact energy feature vectors, then use them as the input vectors of the BP neural network to classify the border and coastal surveillance sound types. Extensive experimental results show that the classification efficiency is up to 94% using this feature extraction method, improved 6% compared with the method based on WPD.

Abstract: Aiming at the disadvantages like the enterprise application system scalability, integration and interoperability is not strong, neglecting the business process integration, the integration platform lacks flexibility and adaptability, based on service oriented and workflow technology system, Service-oriented and for integration of foundation, enterprise application integration system solutions were proposed. To realize loosely coupled, business process integration, high integration and interoperability strong application integration system we need discuss enterprise application integration the architecture and hierarchical model.

Abstract: Along with the rapid progress of heterogeneous networks, multiple user terminals can cooperate via local or short networks as a integrate group to communicate via diverse wide area networks in parallel. This brings forth Concurrent Multipath Transport challenge where the multi flow rate allocation is the key issue. A utility-based model to form a strategy of rate allocation is proposed, in which the user’s QoS demands can be described with user utility function. Moreover, a distributed multi flow rate allocation algorithm that converges to the Pareto optimal is developed. The simulation result demonstrates that the proposed algorithm is efficient to allocate rate for cooperative terminals group in heterogeneous networks.

Abstract: Information and communication are key to the ability of the organization to respond to change. Information and communication technology (ICT) penetrates into all aspects of economy. Now graduate of comprehensive regional higher education institutes (CRHEIs) are main source of workers. Those CRHEIs should improve their quality of learning for their student being good workers. In this paper, we analyses ICT–based learning issues from undergraduates preparing for postgraduate entrance exams and undergraduates seeking a job in Linyi University. The methodology for carrying out the tasks mainly contains questionnaires according to normative Delphi technique. The research provides information and communications strategy which CRHEIs authorities should take in order to properly integrate ICTs in their CRHEIs and get their benefits.

Abstract: As one of the most important parts of the financial organizations nowadays, banking industry plays an important role in not just the area of high-speed operation of the sociaty’s economy but also in the area of currency exchange. The Wave of Information Technology, which has caused a swift-development of the whole world’s economy, brings about both opportunity and challengs never arised to the banking industry. The sociaty, as it is becoming more intellectual and automatic, has post a harder demand for the working efficiency of the banking industry. Therefore, the banking industry must enhance its construction of informationization and automation in order to strengthern its competitiveness as well as the economic construction of service sociaty. Banking office automation will improve the working efficiency along with modernized management level in the light of advanced computer technology.

Abstract: This study is based on 8 large-scale outdoor tests of rock-soil aggregate in Da-Liu Expressway subgrade construction site.and has got the rock-soil aggregate’s characteristics and strength parameters of deformation. Proposing alternate dry-wet effect should be taken into account in the shakedown analysis of rock-soil aggregate slope. This study provides the necessary basis for the Da-Liu Expressway slope stability analysis and control of Settlement. It also provides an important basis for further research which has been widely used in various projects RM systems approach, especially to determine physical parameters of rock-soil aggregate.

Abstract: Traveling wave velocity is the key to the measuring accuracy of the time-domain reflectometry cable length measurement system. The velocity value is affected by many factors. In order to reduce the ambient temperature impact on velocity, the velocity temperature characteristics of time domain reflectometry cable length measurement system are studied. The change law of the traveling wave propagation velocity in the cable with the change in ambient temperature is studied. The velocity temperature error compensation coefficients of traveling wave in the PVC insulated cable is obtained according to the experimental data by measuring the traveling wave velocity in these cables at different temperature. Experimental results show that the measuring accuracy of the time-domain reflectometry cable length measurement system is improved significantly by velocity temperature compensation.

Abstract: Rural settlements of LuGuLake in Yunnan province have an original architectural characteristics —Wooden houses which are shaped by the climate and topographic conditions, local materials, and the social living style. But because of the typical well-dry type construction of the wooden houses which need more massive lumbers to be constructed, it leads to the disappearance of the luxuriant forest. The other building materials such as tamped earth, bricks and stones, reinforce concrete replace the wood materials. The research’s goal is to solve the ecology problem which was brought by wood rooms built by lumbers and the compatible problem between the new houses built by modern materials and vernacular architecture in LuGu Lake.
