Abstract: VOC emission of plastic packing of automobile instrument panels to be harmful for personnel health, in order to effectively control VOC diffusion, needs to analyze the rule of VOC diffusion in the vehicle. In this paper, multi-component model is used to analyze VOC distribution of instrument panel plastic packaging, and influence of the diffusion time, the running status, the well ventilated mode is investigated. The results show that near the panel imports, VOC diffusion is accelerating, and spread to backward along with the time lapse; the automobile movement has propelled to VOC diffusion; ventilation mode had a greater impact on diffusion too.

Abstract: Collaborative design is a new product development to react to the global market. Integration methodology of PDM and knowledge management is proposed in the paper for the increasing the requirement. The methodology is to establish a structure for the collaborative design of the project, design, process, proceed and product. The design is related to the collaborative design which is the main part of the system. Firstly, the basic conceptions are introduced, which can assist to acknowledge the methodology. Secondly, the steps of establishing the integration are proposed, which are eight steps for it. Knowledge management and PDM method are applied for system. Finally, the integration of the system is established. A real example is proposed to introduce the methodology, which is important for the integration of system.

Abstract: Major factors in settlement generation can be summarized as four aspects, the natural environment factor, the social ethic factor, visual esthetics factor, socioeconomic contributing factor etc. nowadays numerous analyses are being conducted in these four aspects, however the vast majority of them are partial, one dimensional researches and the results are often remote from the actual effects. From the perspective of human settlements, the author made a general research by means of systematic approach and discussed how to effectively combine these four aspects to form an evaluation system based on the effect of settlement generation, in order to obtain an ideal outcome of settlement generation.

Abstract: The parameters and controlled dimensions of design objects have an explicit correspondence relation when the parameters are given different values, the different models are created. This paper discusses the parametric modeling technology of truck frame. Building the spare parts by controlling the position of the cross-section, geometry and the numbers of the Key Point .It provides a feasible scheme of the parametric modeling of the truck frame.

Abstract: In accordance with the main flow characteristics of steel and iron production process, some problems are analyzed coming from the making, performance and feedback of the production planning of iron and steel business enterprises in this paper. By using operation research theories and genetic algorithms, one advanced planning model of iron and steel productions suitable of various circumstance and environments is established to set up on the factor of the segment and environment variety. Penalty function is adopted in the course of getting solution. These parameters of scale of father population, crossover probability, mutation probability and penalty factor are combined and optimized. At the same time, to improve these algorithms and the solution process actually, some optimized models and projects were put forward from some plans on the basis of collecting information. It accords with the actual conditions of this enterprise basically that the optimization solution to production plans of real iron and steel enterprise by using the algorithm.

Abstract: Retracted paper: The programming languages approach to von Neumann machines is defined not only by the study of thin clients, but also by the intuitive need for Scheme. After years of significant research into symmetric encryption, we disconfirm the refinement of model checking. Our focus in our research is not on whether the lookaside buffer and Scheme are always incompatible, but rather on presenting an analysis of Scheme (HEW).

Abstract: Retracted paper: Authenticated algorithms and 802.11 mesh networks have garnered limited interest from both systems engineers and system administrators in the last several years. Given the current status of event-driven modalities, theorists particularly desire the refinement of Web services, which embodies the confirmed principles of artificial intelligence. Here we concentrate our efforts on arguing that model checking can be made event-driven, permutable, and wearable.

Abstract: This paper proposes an improved HYT (IHYT) approach to achieve better load balance among substructures for better efficiency of the parallel substructure method. In the IHYT method, the matrix ordering method in SPOOLES, which provides the estimated statistics of numerical workload and nonzero entries of the matrix, are employed for predicting the workload of each sub-mesh, and used as the basis for tuning the element weights to embed the workload prediction phase. In addition, a partitioning kernel–JOSTLE, which can slightly tune the partitioning result from the last iteration and is good for the convergence of iterations, are employed as the partitioning kernel. The numerical experiments show that the IHYT further achieves better load balance of substructure condensation and leads to better efficiency of the parallel substructure method than HYT approach.

Abstract: Aiming at existing some problems, such as large calculation, not extensive category of defect recognition, and not accuracy of recognition result, this paper reanalyzes characteristic construction’s proceed of moving image by human vision, and proposes a new ‘super-fuzzy’ characteristic model of fabric based on pre-judgment mechanism. In this model, ‘super-fuzzy’ factor is introduced, and pre-judgment mechanism on coarseness set is constructed. So the characteristic can be modified with optimization according to actual condition of image. From experiments, results show that this characteristic model has such features as calculation is less, fabric images analysis is fast, fabric and defect category is extensive, pre-learning of mechanism doesn’t need, and better application is expected.

Abstract: Aiming at current situation of absenting effective texture feature model for irregular defects of fabric image, this paper proposes a new feature model with “mean range” texture, which can express irregular defect of fabric better. In this paper, the definition of irregular defect is given, and rule model expressing fabric texture is established. At this basis, feature model of mean range texture is proposed, which can express irregular defects for all kinds of fabrics. After a large number of experiments, we conclude that feature with mean range is simple and effective, express fabric texture better, can show feature mutation of irregular defect, and offer reliable texture feature model for continue relating quality detection of fabric.
