摘要：
Fracture toughness K(IC) is one of the important parameters to characterize the general mechanical properties of materials, Tests for determining K(IC) are usually performed on a fatigue test machine. However, for some large structure parts, such as hydropower generator rotor, weighing several tons or even one hundred tons, it requires large samples for testing, which results in the large loss of the materials.. In the present work, we use a small sample to measure its J(IC), and the consistency of J(IC) and K(IC) on characterizing fracture toughness of small size samples was analyzed. Both the experimental results and theoretical calculations show that, under certain experimental conditions, J(IC) can replace K(IC) to characterize the fracture toughness.
摘要：
This paper studies an inverse coefficient problem of a parabolic equation where the final observation is given, the unknown coefficient depends on both the space variable x and the time variable t. Based on the optimal control framework, the inverse problem is transformed into an optimization problem and a new cost functional is constructed in the paper. The existence of the minimizer of the cost functional is proved, and the necessary conditions which must be satisfied by the minimizer are also given.

摘要：
with the rapid development of the network, The World Wide Web has become a large of information repository storing millions of information. Recently, How to find relevant information related to a specific topic has become a hot topic. An alternative way is to employ search engine to answer the query issued by users. Typical search engine is composed of three pipelined components, namely, a crawler, an indexer, and a query processor. In this paper, we give an overview design of search engines. In particular, we focus on the design and the implementation of the crawler using .Net techniques

摘要：
Carbon Fiber Reinforced Polymer can be used as suspender in boxed steel arch bridge which is of good physical and mechanical performance. A type of thread anchorage for CFRP has already developed and its adjustably telescopic range is 10 cm that is used for any diameter below 10 mm. According to the similarity principle, a scale model for CFRP tied arch bridge has made in this paper. Meanwhile, stress and deformation performances about the model have been analysised respectively. During applying concentrated force and distributed force at the mid-span, the tensile force for suspender is large because of its vertical deformation and its results are coincide with the one of model analysis, at the same time, A compressive stress for the relative steel boxed sections is big. Test results show that the stress and deformation performance for CFRP steel boxed arch bridge are well. It can be applied for the similar bridges for CFRP suspender.

摘要：
In this paper, a reasoning model is proposed for energy efficiency task allocation in wireless sensor network. The presented energy efficient contract net protocol is used to implement the negotiation process. Multi-issue scoring function can evaluate the offer with multi-issues in a quantifiable way. An energy threshold is brought to decrease communications which will turn out to decrease nodes’ energy consumption. And the usage of energy threshold also promote the nodes with high level energy have more chance to implement tasks. The simulation results show that the allocation model has outstanding performance maintaining a fair energy balance and is energy efficient in negotiation process.

摘要：
Tunnel excavation is often done in underground engineering such as civil tunnel construction and mine excavation. The numerical simulation can output colorful results to interpret the tunnel excavation effect more easier. Among all the numerical simulation methods, fast lagrangian explicit finite difference code of continua (FLAC3D) is widely used to solve practical problems, especially in field of elasto-plastic characteristic and construction procedure. So in the present paper, 3 steps of excavations in a tunnel is modeled by FLAC3D to present the stress and displacement distribution, and give guidance for the real practice.

摘要：
Differential evolution (DE), a fast and robust evolutionary algorithm for global optimization, has been widely used in many areas. However, the success of DE for solving different problems mainly depends on properly choosing the control parameter values. On the other hand, DE is good at exploring the search space and locating the region of global minimum, but it is slow at exploiting the solution. In order to alleviate these drawbacks of DE, this paper proposes an improved self-adaptive control parameter of DE, referred to as ISADE, for global numerical optimization. The proposed approach employs the individual fitness information to adapt the parameter settings. Hence, it can exploit the information of the individual and generate the promising offspring efficiently. To verify the viability of the proposed ISADE, 10 high-dimensional benchmark problems are chosen from literature. Experiment results indicate that this approach is efficient and effective. It is proved that this approach performs better than the original DE in terms of the convergence rate and the quality of the final solutions.Moreover, ISADE obtains faster convergence than the original self-adaptive control parameter of DE (SADE).
