摘要：
In this paper a wavelet-based HVS characteristic watermarking algorithm for copyright protection of digital image is presented. Instead of using a random sequence, a visually meaningful gray scale logo is used as watermark. Our techniques apply the Arnold transform to disturb watermark and split the wavelet coefficients of the low frequency into small blocks. Watermark is embedded into the maximal absolute value of these coefficients selected based on the weight factors calculated by exploiting the human visual system (HVS) characteristics. The experiment results demonstrated the new algorithm is robust for scaling, rotation attack, JPEG compression and noise attack.

摘要：
Multipath routing can reduce routing update, increase bandwidth and improve data transfer rate of ad hoc Networks. However, there exists serious collision among multiple paths. Energy minimum and collision avoidance are incompatible, and limited battery capacity presents major challenges for collision avoidance. In order to find a tradeoff between them when transmitting data simultaneously, this paper proposes a collision-constrained minimum energy node-disjoint multipath routing algorithm (ECCA) for ad hoc networks. The ECCA defines correlation factor to weigh the collision probability among node-disjoint multipath, then calculates an upper limit for correlation factor according to service requirement, finally finds a minimum energy node-disjoint multipath routing to satisfy the limit. Our preliminary simulation results show that ECCA can significantly reduce the packet loss rate and energy consume, but not prolong routing time.

摘要：
A non-cooperative game framework for pricing in high-speed networks is presented in this paper. The approach which adopted is referring to mixed strategy, by which the user can modify his budget according to the market condition and the global synchronization can be avoided. The unique Nash Equilibrium of our game framework was analyzed and the simulation results are given. Then we finish the paper by drawn some conclusions and indicating some directions for future research.
摘要：
In this paper the optimized Genetic Algorithm (GA) is proposed to solve the automatic generation control (AGC) problem of cascade hydroelectric power systems. The proposed genetic algorithm uses the real number encoding to represent a solution to the problem. Elitism operator is executed to prevent the best individuals from varying. Adjusting low-grade Individuals scheme is used to improve population fitness. Two kinds of crossover and mutation operators are performed to maintain gene diversity and to avoid premature convergence. The paper presents an actual application on the optimization of AGC for a cascade system composed by three hydroelectric plants located in the qingjiang System. Test results are used to verify the validity of the proposed algorithm.

摘要：
This paper presents a novel optimized distributed dynamic wavelength assignment algorithm for the wavelength routing optical network(WRON) based on the revised result of reference[5,6]: Fast Distributed Dynamic Lightpath Setup Algorithm(FDDLSA). By adopting two kinds of new optical link release mechanisms (ahead and timeout release) in the process of networks nodes setting up a link, the new algorithm can reduce the blocking probability significantly and release the burden of a router. The effectiveness of the algorithms was verified through the simulation on NSF net (Nature and Science Foundation) of USA: it can reduce the blocking probability 8% less than reference [5]'s algorithm, at the same time it can reduce the optical path setup time greatly.
摘要：
Chinese Sentence can be divided into two types by its structure: simple sentence and complex sentence. This essay mainly discusses about Chinese simple sentences which are classified into two forms: the ones named "small sentence" are those can be used individually, and the ones called "clause" which are parts of Chinese complex sentences can't be used separately as small sentences. In this paper, we analyze the static structure of Chinese simple sentence and its relationships with Chinese complex sentence and paragraph. Then we introduce an approach that has never used in Chinese information processing area to construct the ontology meta-model of Chinese simple sentence. This will facilitate the further researches on the ontology model of Chinese complex sentence.

Chinese grammar metamodel Metamodeling architecture Chinese information processing
摘要：
This paper attempts to arrange the Chinese grammar components in a hierarchy and construct the Chinese grammar metamodel. Establishing the formalized Chinese grammar system is essential for computer to analyze and process Chinese automatically. The objective of this metamodel is to model semantics associated with the Chinese words. This paper introduces the modeling technique in the area of software engineering into Chinese information processing. To achieve this purpose, this paper firstly defines a four-layer Contemporary Chinese grammatical architecture by using the Model Driven Architecture (MDA) for reference. Then, the metamodel is defined in the framework of the predefined four-layer Chinese grammar architecture and the main Constructs. rules, and constraints of the metamodel are finally identified.

摘要：
Despite the rapid development of the resilient packet ring (RPR) technology, the available bandwidth allocation algorithms for RPR networks do not provide satisfactory solutions to meet their performance requirements. To attack this problem, this paper proposes an algorithm, which we call the distributed bandwidth fair allocation (DBFA) algorithm, that achieves the key RPR performance goals, i.e., fairness, high utilization and spatial reuse. The algorithm is distributed and uses a simple proportional control mechanism to allocate bandwidth among competing flows in a weighted manner. In order to realize global coordination on the entire RPR ring, one global control packet traverses around the ring to make every node on the ring dynamically adjust its sending rate, so it eventually achieves its fair share of the ring bandwidth. As a result, global fairness as well as high utilization and maximal spatial reuse over the RPR ring can be achieved. Simulation results verify the satisfactory performance of the DBFA algorithm.

摘要：
A novel model has been proposed in this paper, it considers a pair of clients as the smallest gene, which was assigned secretion respectively based on proper modification of ant algorithm. We transformed the problem of client selecting server to that of server selecting client. And we adopted GT-ITM as Internet topology generator to generate transit-stub model topology for simulation. In the case of large-scale network topology, the simulation results show that the modified ant algorithm performs better than other heuristic algorithms such as the widest path and the optimized widest path ones.
