Abstract: The article uses ferric sulfate as oxidant, and makes Galena oxidation test in the oxidation of different concentrations of medium, when pH is 2, and temperature is 50oC and 25oC. It analyzes the effects of the rate of Galena oxidation from temperature and oxidation of medium concentrations. In the conditions of 50oC, Fe2(SO4)3 as an oxidant, the solution concentration of 100mg / l, the reaction is quick. When the higher the concentration of solution, the higher the solution concentration of sulfate ions, the easier it is generated PbSO4 precipitation, impeding the reaction. In 25oC, the reaction is very slow or even not to.

Abstract: This paper presents the cases of three Association for the Advancement of Artificial Intelligence (AAAI) General Game Playing (GGP) Competition winners named Clune player, Flux player and CADIA Player in detail. The paper describes architectures of three players and how they work. The paper gives insight into the approaches the three players take and key features of their models. Lastly, this paper makes further analysis about the advantages and disadvantages of the three players’ models and makes some comparisons among the three players.

Abstract: Many calculations in engineering and scientific computation can summarized to the problem of solving a polynomial equation. Based on Sturm theorem, an adaptive algorithm for real root isolation is shown. This algorithm will firstly find the isolate interval for all the real roots rapidly. And then approximate the real roots by subdividing the isolate intervals and extracting subintervals each of which contains one real root. This method overcomes all the shortcomings of dichotomy method and iterative method. It doesn’t need to compute derivative values, no need to worry about the initial points, and could find all the real roots out parallelly.

Abstract: Using technology, cooperation among peoples, lawyers are very special, it is rare. We believe that these two professionals working closely together in the field of ODR are essential. The co-operation we have in mind exists in drafting legal principles and technical requirements to develop and eventually implement an online negotiation environment. The online environment should different from other online negotiation environments in that the legal principles and technical requirements, on which the environment will be based, are developed in close cooperation and therefore fully adjusted to each other.

Abstract: Ant colony algorithm is a kind of effective combinatorial optimization problem solving algorithm has been increasingly, thorough research, and gradually get used. Ant colony algorithm is a set of parameters, the algorithm, a lack of adequate experiences often. The paper has put forward a single genetic character of ant colony algorithm. Will the ant colony algorithm each search results as the initial population, single genetic improvement, for the shortest route optimization. In the traveling salesman problem of the experiments prove the effectiveness of the proposed algorithm.

Abstract: Sulphur content in pig iron is one of the most important indices to represent the quality of liquid iron in blast furnace. In order to timely control sulfur content, a mathematical model is developed to predict the sulfur content in pig iron. Compared with the conventional artificial neural network model, a new method is developed to integrate artificial neural network with genetic algorithm. The genetic algorithm with the binary coded chromosome is used to optimize initial neural network weights. In this project, the first aim is to train the model by integrating artificial neural network with genetic algorithm according to the past processing variables. The second is to predict the next sulfur content based on the training result in the first step and according to the current processing variables. Compared with only using artificial neural network model, this developed method can improve the predicted accuracy. From practical applications, it can be found the model is exact and reliable to predict the sulfur content in the pig iron of blast furnace.

Abstract: In order to obtain the four quadrants hydrodynamic performance of open water propeller by means of CFD, a mathematic model of three dimensional coordinates points was established and programmed using Matlab based on the basic parameters of propeller. A smooth model propeller was made by importing these points into front end software. Then taking AU model for example, numerical simulations of propeller turning ahead while going ahead, turning ahead while going astern, turning astern while going ahead and turning astern while going astern were carried out. At the same time, the thrust and torque coefficients were presented. The simulation results showed good agreement with the results of tank test. The influence of mesh generation and computational domain on open-water performance were also discussed.

Abstract: Compare to the sequential Broyden method, an asynchronous parallel Broyden method is presented in the paper. We suppose that we have processors, which are divided into two groups. And the first group has processors, the second processors has processors, while the two groups are asynchronous parallel. If we assume that the objective function is twice continuously differentiable and uniformly convex, the global convergence of the algorithm is given. And under the same conditions, we show that the parallel Broyden method is superlinearly convergent.

Abstract: In this paper, an improved particle swarm optimization-ant colony algorithm (PSO-ACO) is presented by inserting delete-crossover strategy into it for the shortcoming which PSO-ACO can’t solve the large-scale TSP. The experiments results show that the PSO-ACO has better performance than ant colony algorithm (ACO) on searching the shortest paths, error and robustness for the TSP.

Abstract: In the past several years, there have been dramatic changes on the Web services landscape．After the traditional XML-PC web service, a new style-Representati0nal State Transfer (REST) is applied to Web services. In addition, the telecom operators have provided different APIs. OneAPI standards have been proposed. This article mainly introduces OneAPI standards and REST architecture. Some OneAPI supplied by GSMA website to provide REST service. Sample program implements can get the user address though the OneAPI.
