Abstract: Numerous studies reported that mixtures of Rare Earth Elements (REEs) could produce quite sensational growth-promoting effects in all categories of farm animals; but many people thought that REEs could affect human healthy. Therefore, experiments were done to understand the effects of La2O3 on red-eared sliders. The results showed that lower dose of La2O3 could probably improve the metabolism of Red-eared Slide turtle, and the higher dose of La2O3 could probably cause pathologic reaction. Lanthanum trichloride (La) could cause the Histological changes in tortoise livers. A very lower dosage of La2O3 could damage the livers of red-eared slides obviously though diversity pathway. The wild animal should be protected from harm in the RE diggings. If the RE is used or must be used as an additives in animal foods, an appropriate dose of RE was necessary, and the safety evaluation should be done.

Abstract: Aiming at many problems of existing feature model of fabric defects detection, such as large calculation, not exact expression and not extensive defects categories, a new ‘super fuzzy’ feature is proposed in this paper. This new method can solve above problems. Firstly, a general model of ‘super fuzzy’ is given. Some cent-characteristics denoted different kinds of defects are combined according to weight factor, and each cent-characteristic is guaranteed in a same quantity grade by modified constant vector. Then, a concrete ‘super fuzzy’ feature model combined by four cent-characteristics for fabric materials is obtained, and this model is optimized. Finally, after some programs experiments, concrete effect of fabric materials defects denoted by ‘super fuzzy’ feature is validated. Results show that ‘super fuzzy’ algorithm is effective for fabrics defects detection with different texture considering fabric characteristics, and defects feature of many fabrics is expressed quickly and exactly with no pre-supervised learning.

Abstract: Aaccording to the cases that the synthetic quality evaluation system for fabric is not reasonable at present, a new synthetic quality evaluation system for fabric on fuzzy theory is proposed. This new evaluation system is made of foundation layer, evaluating layer and result layer. In foundation layer, the quality standard model and evaluating data model based on multi-indexes are proposed, and the calculation method of each index value in these models is given. In evaluating layer, according to the problem that the result of existing closeness algorithm has greatly repeated, a new evaluation algorithm is proposed. In result layer, two formulas which are continuous result and discrete result are given. Also the accuracy and rationality of this evaluation system is validated by some examples in this paper, and the effect of evaluation result by the primary-secondary indexes, the significance of closeness, the expansibility of model, the accuracy of system and the application method are made analysis. At last, the conclusion shows that this system can make the synthetic evaluation for fabric quality rationally and accurately.

This accounting and billing system mainly addresses to resolve the problem of accounting and billing of resources usage and provides good quality of services for users. This paper will introduce the basic implementing mechanism, collecting process of resources usage information, resource price policy and etc. The algorithm which gets cost by resources object with dynamic price is proposed. It suits the characteristics of HPC Cluster and can reduce the load of the center server and reflect the usage of resource.

Abstract: Self-compacting concrete (SCC) has been widely used in engineering for improving the product quality and efficiency at the construction sites, enhancing the working conditions and the appearance of concrete. Workability is an important property of SCC. But none of a single method has been developed for evaluation workability of SCC efficiently. Aiming at the quality control of fresh SCC, a fuzzy comprehensive evaluation method for evaluating workability of SCC was put forward and a case study was done by measuring slump, slump flow, L-box ratio, J-ring flow, bleeding and sieve segregation of fresh SCC in the present paper. Evaluation results indicated that fuzzy comprehensive evaluation method can give a quantitative evaluation of workability of SCC and it is convenient to establish an expert system for controlling the quality of fresh SCC by using fuzzy comprehensive evaluation method.

Abstract: Based on the idea of the neural network, intelligent computing methods are used to analyze temporal and spatial data. We present the temporal and spatial autocorrelation moving average (STARMA) model based on the in-depth systematic study on time sequence of hybrid model. Firstly this paper uses radial basis function neural network to extract the temporal and spatial sequence which is non-stationary caused by large-scale non-linear trend, secondly this paper presents STARMA modeling of small-scale random spatial and temporal variation. Comparative analysis between the original data and the forecasting data shows that proposed hybrid model has better performance of fitting and generalization.

Abstract: This Paper introduces a temperature detection system in beer fermentation. A temperature monitoring system with characteristics of bus topology structure is composed of industrial computer, temperature detector, bus converter, transmission bus and especially 1-wire digital temperature sensor DS18B20. Four-core cable is used to form a tree-like or star-like network, in which 54 digital temperature sensors existing on 18 fermentation tanks can be connected. The quantity of junction wires between temperature sensor and computer will be reduced greatly. Temperature detector provides power supply for bus converter and DS18B20 through Four-core cable. Because bus converter has used hardware fault detecting technology, the fault temperature sensor can automatically detach from the main bus and will not affect normal working of other sensor in network. So to solve the problem of a certain sensor or branch's damage causing the paralysis of entire bus. The length of detecting temperature bus can reach more than 500 meters. These all make system maintenance and expansion easy. The experiments show that this system is characterized by high intelligence, high-precision, capability of making temperature test on multi-points and compensating function. The method has a good applicable value to the temperature test.

Abstract: With MAS(Multi Agent System)coordinated technology and market bidding game rules, a grid resource allocation model based on market economy was introduced, which could show the relation between supply and demand. The utility function of consumer was given; The results of emulation test showed that the resource allocation algorithm could be a reference to resources of consumers and the approach significantly improves resource utilization, which made the allocation of the whole network resource tend to be more reasonable.

Abstract: An ultra-wide band planar monopole antenna is presented in this paper. This antenna uses a pentagonal patch as radiation unit and is fed by a microstrip line. The relevant simulation is performed by using Ansoft HFSS. The return loss curve and the radiation patterns of this new antenna are given. And the effect of the size of the various parts of the antenna on the reflection loss is analyzed. Experimental results show that the proposed antenna provides an ultra-wide bandwidth (1.70~12.90 GHz) for return loss less than -10dB (VSWR<2). It is suitable for current ultra-wide band communication systems.
