Abstract: Food supply chain is a complex process. The author develops a model that will provide both researchers and practitioners with a means of determining the optimal ordering policy for multi-products in fresh food supply chain. By using computer simulation. this paper conduct for a numerical analysis to the ordering policy of products of a food company in Hubei province to analyze the properties of total cost functions under each of the six different ordering policies and proposes an approximate optimal ordering policy of multiple products. Based on the models and analysis, it is found that agglomeration effect plays an important role in determine ordering policy of multiple products.

Abstract: The yarn tension is a key factor to accurately control carpet pile height, which changes with the yarn path and the path flexing. The purpose of this paper is to find the relationship between yarn path and yarn tension and provide a basis for the yarn tension controller design. Firstly, tufting equipment system components and basic principle of tufting carpet is introduced. Then, the yarn path during weaving tufting carpet including yarn feeding parts, yarn guiders and tufting needle is constructed and yarn flexing in the yarn path is analyzed. After discussing yarn tension change caused by the path flexing, it is concluded that yarn tension changes with the tufting needle position and periodic change with the yarn flexing periodic change.

Abstract: . In daily life, expanded polystyrene foams (EPS) are widely used as packaging material and waste EPS has caused lots of environmental pollutions because it cannot be decomposed in nature. In this study, the machining process is developed of a reinforced foam packaging material by hot press molding, potato starch and birch fiber as the main raw materials. Analysis of the dosage of the birch fiber, starch adhesive and foaming agent and how do they affect the mechanical properties. Experiments show that material compressive strength is good and foam well-distributed, when the birch fiber content is 20%-25%, adhesive content is 30%-35%, and birch fiber amount is 10%-15%, the material has fine performance, and the cells are well distribute.

Abstract: The paper describes the operation principle of optically powered sensor to measure differential pressure. Its probe powered by LD light only consumes tens micro watt .The optical source for power and signal can be transmitted to and fro by a single multiple mode optical fiber. The power and signal lights have different wave length. The system design is introduced and its parameters are selected. The signal and power are transmitted by fiber, and the probe is low power consumption, so this pressure measuring system can work in flammable and explosive environment. Adopted differential measuring signal processing technology, its anti-noise ability is improved. Experimental results show that this system has high precision and high reliability.

Abstract: With living standards improve, more and more attention of intelligent building. Follow that, required facilities of life, entertainment, security and other more and more to connect into the network. The IP address of the traditional IPv4 space is facing the depletion, facing a crisis of a large number of the access device; The IPv6 addresses solve such crisis. In this paper, framework an intelligent building system based on Ipv6, to achieve access to smart sensors, and to intelligent home facilities purposes.

Abstract: We describe a new pattern recognition method which is based on the concept of geometry theory. The method identifies subsets of the data which are embedded in arbitrary oriented lower dimensional space. We definite a kind of mapping, and study its property. Covering subsets of points are repeatedly sampled to construct trial geometry space of various dimensions. The sampling corresponding to the feature space having the best cognition ability between a mode near zero and the rest is selected and the data points are partitioned on the basis of the best cognition ability. The repeated sampling then continues recursively on each block of the data. We propose this algorithm based on cognition models. The experimental results for face recognition demonstrate that the correct rejection rate of the test samples excluded in the classes of training samples is very high and effective.

Abstract: Many questions in natural science and engineering are transformed into nonlinear equations to be found, Newton iterative method is an important technique to one dimensional and multidimensional variables and iterative process exhibits sensitive dependence on initial guess point. The property of chaos sequences produced by one dimensional simple chaos mapping method with infinite collapses in finite interval was analyzed. For the first time, a new method based on utilizing one dimensional chaos mapping method with infinite collapses to obtain locate initial points to find all solutions of the nonlinear questions was proposed. The numerical examples in linkage synthesis and approximate synthesis show that the new method is correct and effective.

Abstract: Draw on the trust relationship of human society, domain model and domain trust are introduced to build domain-based level trust manage model (DLTMM). In various domains, according to physical services characteristics of their own, entities abstract representative attribution. According to their preferences the service requester preferences comprehensive evaluate the service attributions, and to determines whether transaction; After trading, the service requester will calculate the difference degree of quality of service according to the actual quality of service and the claimed quality of service, and then judge the trust degree of service provider. The simulation results show that the model can more accurate assessment of the trust entity, to some extent effective against malicious attacks, which proves the validity and accuracy of the model.

Abstract: The bio-drying characteristics and its influencing factors of paper mill sludge (PMS) were investigated detailedly, by means of the heat generated by aerobic degradation of the organic substances in the PMS. In the orthogonal experiments, the good results were achieved with the followed optimization technics: starch (25.0g/500.0g), sawdust (40.0g/500.0g), inoculation (15.0mL/500.0g) and KH₂PO₄ (5.0g/500.0g). During bio-drying, the matrix temperature increased to 47.2°C within 12-24h rapidly under the given operation parameters, and the maximum was about 48.0°C. In the whole process the pH changed in the range of 6.11-7.87. The quantity of amylolytic bacteria reduced to the minimum in the first day, and the amylolytic bacteria grew well until the process of bio-drying finished. The ATP content was increased drastically in the first day and peaked in the fifth day, with the maximum ATP content was about 6.4×10^-6μmol/g. When bio-drying of PMS was finished, the VS content and moisture content (MC) reduced from 58.4% to 49.5% and 62.2% to 50.3% respectively.

Abstract: The paper presents a method of the serial communication codes of the testing interface card by using the serial monitor software and ROBO Pro graphical software, and the research on the movement control system is based on Fischertechnik interface. The system software with Windows style is developed by using the serial communication function of advanced programming language VB6.0. The serial interface program through the MSComm control of VB6.0, and the status of Fischertechink interface could be detected through the received communication codes, sending communication codes to control the movement of mode.
