Transaction operations are supposed to be supported in ForCES-based distributed systems (FDS). In this paper, we propose a generic transaction model in the light of the characteristics of transaction process in the FDS. The model is a practical and adaptive nested transaction model that extends more support for interoperable transactions and flexible transactions. To ensure the commonality and compatibility of FDS, we consider each Forwarding Elements (FE) as a black box with an exception that it supports the well-known transaction protocol defined in the ForCES protocol. In our model, an interoperable or a flexible ForCES transaction is decomposed into subtransactions with corresponding dependency relations among them. Each subtransaction is a basic transaction that can be supported by the transaction protocol without any private extension. We propose a binary tree model to denote a ForCES transaction, and the transaction execution order of a successful commit is definite with the aid of the transaction B-tree. We also analyze some relative issues, such as how to ensure ACID properties, and presents methods to achieve global serializability and to enhance the efficiency of transaction execution.

Aimed at overcoming the deficiency of methods applied to existing evaluation of enterprise managers’ performance, this paper introduces an evaluation method based on unascertained measurement. In the evaluating process, for the second-rate indicators we use information entropy to determine their weights, and for the first-rate indicators we use the Analytic Hierarchy Process to determine their weights, realizing the combination of quantitative and qualitative analysis, achieving the unascertained comprehensive evaluation results of performance of enterprise managers. Then we take an example to analyze and explain the model. This result proves that unascertained measure model with a more simple calculation process and a higher recognition accuracy is applicable to the performance evaluation of enterprise managers.

Voice Activity Detection is considered as a crucial part of the speech signal processing. In order to improve the accuracy of Voice Activity Detection under the high-noisy environment, an algorithm named distance entropy is proposed. The algorithm firstly enhances speech with short time spectral amplitude, and then utilizes the robustness of cepstral distance and spectral entropy. The experimental results show that this method performs well on anti-noise, and is more accurate to detect the endpoint in low SNR environment.

In order to satisfy the requirement of aerocraft’s multi- transmission for further development, the paper leads to a resolution about on-board dynamic reconfigurable Spacewire routing technology. Based on the network level analysis of Spacewire standard, it built the architecture of router with wormhole routing theory. A simulation model of router had been set to verify the design, and braking-problem from wormhole routing-blocking had been solved with BWR. And a prototype of dynamic reconfigurable router had been built by using the characteristic of high-speed processing and dynamic reconfiguration of FPGAs.

since 1970’s, business environment had changed fundamentally. The customer’s demand is various and personal, the market competition is becoming more intense, the enterprise’s competitive advantage depends on the market strain capacity of the enterprise. The collaborative design grid platform is based on the advanced networking and the middleware technology. It provides the long-distance design task execution, the data accessing, the choosing and analysis. It simplified the design and implementation of the new products. This technology helps to realize the resources sharing among enterprises and advantage complementation, and strengthen the market competitive power. Virtual Organization is the organization form designed by the collaborative design grid. This article studied the virtual organization model under the environment of collaborative design grid; established Virtual organization model based on OGSA, and gave the general process for virtual organization partner choice and virtual Organization establishment.

Based on time series data of Suzhou from 1991 to 2008, this paper carries out empirical research on the spillover effect of foreign direct investment by using ADF test, Granger causality test and regression method. The result shows that foreign direct investment has spillover effect to GDP which is the Granger cause of GDP in Suzhou. Meanwhile, the inverse relationship does not hold. We also find in the short run, foreign direct investment can increase GDP significantly and positively, but in the long run, it has negative effect on GDP of Suzhou.

The need for an effective management of knowledge is gaining increasing recognition in today’s economy. To acknowledge this fact, new promising and powerful technologies have emerged from industrial and academic research. With these innovations maturing, organizations are more and more willing to adapt such new knowledge management (KM) technologies to improve their knowledge intensive businesses. Therefore, the objective of this paper is to address this challenge and introduce a framework for the development of enterprise knowledge management systems that will support both the business process and the technological knowledge infrastructure. We also discuss in this paper, the role of aspects and distributed middleware framework in enterprise knowledge management systems development.

With the development of Terrestrial 3D Laser-scanning technology, as the one of main methods of earth observing architecture, Terrestrial 3D Laser-scanning technology is increasingly widely applied in the field of ancient architecture protection. Triangulating a set of scattered 3D points is a common approach but a difficult problem to surface reconstruction from unorganized point clouds. Large wood structures are common structure in ancient architecture. Because the amount of point cloud data of it is very large, universal triangulation algorithms don’t adapt for. On the basis of full analysis of the characteristics of the ancient buildings’ large wood structure, the algorithm was proposed in this article, which integrated with the cylindrical projection and tangent plane projection triangulation. Experiments show that the method is more efficient and effective support for the regular shape large wood structures.

In this paper, we discuss the opportunities for global optimization of networks, which takes the user perspective into account. We state three fundamental problems in this approach, which are the variable (and usually also large) number of objectives, the Arrow impossibility theorem, and the unavoidance of the fact that the feasible space may contain solutions, where some objectives are extreme. To overcome these problems, we propose to achieve at least fairness among the fulfillment of user objectives, if optimality (e.g. in the sense of Pareto-optimality) is not possible. We also outline a generalized approach to fairness, based on fairness relation. Heuristic methods are available to handle the corresponding search problems.
