Abstract: Air filtration media are designed for disposable, but in some application, it should be used for some times with water cleaning. Through experiments, the performances of filter, which are cleaned with water for many times, including filtration efficiency, resistance, dust capacity are studied in the paper. The experimental results show that water cleaning has less effect on filtration efficiency, resistance and dust capacity of the filter media. Therefore, air filtration media can be used repeatedly by way of water cleaning.

Abstract: The paper bases on maximum allowable concentration (MAC) drawed up by the state, throughs the Gaussian plume model to calculate the spread area of hazardous chemicals, and puts the spread area into 3D scene. Thus, it can providers a visualization decision support tools for the commanding offcers.

Abstract: With the increase of gas drainage volume and gas drainage requirement of coal seam in China, more and more attention to gas drainage effect of coal seam is paid. The gas flow law and borehole sealing mechanism are briefly described, the borehole sealing technologies of different materials are analyzed and the requirements are obtained as follows: 1Sealing materials shall have permeability. 2Sealing materials shall have expansion. 3The strength and hardness of sealing material can not be too high. 4Sealing materials are compact; sealing materials shall have certain strength. 5Sealing materials can be obtained easily and their price shall be low. 6Sealing process is simple and is constructed easily. Finally, the high polymer foam sealing technology, the mechanical elastic sealing technology, borehole packer sealing technology, the new pressure grouting hole sealing technology, yellow clay borehole sealing technology and rubber ring (or capsule)-sealing fluid sealing technology are briefly analyzed, the advantages and disadvantages of the borehole sealing method and the sealing materials used in coal mines in China are summed up. The results can provides the reference for selection of borehole sealing methods and sealing materials of gas drainage in coal mines.

Abstract: A physicochemical model of sodium silicate melts in the region from 0 to 67 mol. % Na₂O is constrained. A database of sodium silicate melts is formed and coordinated with the help of high-temperature Raman spectroscopy data. The formed model shows quantitative estimation of component changes in melts vs. temperature and composition.

Abstract: In this work, was considered the thesis that the optic properties of anti-reflecting and the satin-like glasses can improve the efficiency of solar panels that use plastic covertures or conventional glasses as coverage. The infrared radiation that is not turned into electricity with the conventional photovoltaic cells, increments the panel surface temperature, of the supporting structure and of the photovoltaic cells. For above 35oC it is possible that some cells stop converting the visible light in electricity due toparameters dispersion effect, with this, the efficiency of electric generation is diminished. In the electromagnetic spectrum, the wavelength of infrared radiation is since 800nm, the anti-reflecting glasses transmittance is since430 to 680 nm, while the satin-like glassestransmittance issince 500 to 600nm, therefore for thiscause the infrared transmittance is not observed. In this work, it was proved that the use of anti-reflecting glasses and satin-like glasses improves the conventional solar panels efficiency. The results suggest an efficiency of 31.6 % of solar energy conversion with the anti-reflecting glass, and 36% with the satin-like glass, when these were used as cover panel photovoltaic.

Abstract: Color space conversion (CSC) is an important kernel in the area of image and video processing applications including video compression. CSC is a compute-intensive time-consuming operation that consumes up to 40% of processing time of a highly optimised decoder. Several hardware and software implementations for CSC have been found. Hardware implementations can achieve a higher performance compared with software-only solutions. However, the flexibility of software solutions is desirable for various functional requirements and faster time to market. Multicore processors, especially programmable GPUs, provide an opportunity to increase the performance of CSC by exploiting data parallelism. In this paper, we present a novel approach for efficient implementation of color space conversion. The proposed approach has been implemented and verified using computed unified device architecture (CUDA) on graphics hardware. Our experiments results show that the speedup of up to 17× can been obtained.

Abstract: In this article, a polyhedron biosensor based on the surface plasmon resonance technology in heterodyne interferometry is proposed. The sensor is designed as the polygon prism that is made of BK-7 glass with the refractive index of 1.51509. As a heterodyne optical source is launched into the biosensor, the phase difference between s-and p-polarization components can be obtained. The related parameters of the tested medium can be achieved after some calculations. The best resolution of the sensor can reach 5.5×10^-7 refractive index unit (RIU). The polyhedron biosensor has some merits, e.g., a simple optical setup, easy operation, high measurement accuracy, high resolution, high sensitivity, and in real-time test, etc.

Abstract: Since 2011, many Japanese DSC manufactures were anxious to explore some new possible solutions, in order to fill up the niche of technical advanced models or nostalgia models for special users, such as: Canon PowerShot SX50 (50x optical zoom), Panasonic LX7 (F1.4 Aperture), Fujifilm Xpro-1(nostalgia),and Canon IXUS 510 HS(Wi-Fi), NikonD3200(Wi-Fi),SamsungNX1000(Wi-Fi), Nikon S800C(Android). In fact, in 3C market, both hot-selling Smartphone (Multi-function Cell Phone) industries and DSC manufactures may have mutual interested which can work together to produce better and suitable photo components ever before. It is a new trend for Smartphones have better photo quality, and DSCs have Wireless Sharing Technique (Sharing Photos by Internet). Basically, this Wireless Sharing Technique for DSCs, only existing on relatively inexpensive, non-professional, DSLR-like, and EVIL cameras before late 2012, but are highly adapted since early 2013.This is the main target we are looking for, and we check every possible point what could be the real advantages and disadvantages for those bright new DSCs with Wi-Fi system. In our experiment, we collect more than 300 cases from the telephone survey during September 2012 to January 2013. Total of 210 cases fulfilled with the conditions. To probe mainly into the relationship between Wi-Fi DSC confidence level and 3 potential groups of people: IT administrators (IT), Multimedia Specialist (MS) , and college student (CS). We are probe into this highly competitively market with brilliant creative design, and hope to offer an objective suggestion for both industry and education administers. .

Abstract: This paper presents the design of the functional safety temperature transmitter and reliability analysis to develop the certified safety related product with independent intellectual property rights. According to the functional safety standard IEC61508 and the 1-out-of-1 and Diagnosis (1oo1D) architecture of the temperature transmitter, self-diagnostic methods are proposed. At the same time a Markov model is established to assess the reliability of the transmitter quantitatively. Analysis results show that safety integrity level (SIL) is SIL2 and safety temperature transmitter complies with functional safety requirements and safety integrity level requirements.

Abstract: Supply Chain is a network of organizations and their associated activities that work together to create value for the customer. This paper aims to present comprehensive and systematic negotiation and recommendation framework for e-Supply Chain by using multi-agent approach. Such framework should receive suppliers material offers, rank the suppliers, and provide recommendations for customers. On behalf of the standard tasks like interface, recommendation, negotiation, and data retrieval, some agents have designed to use neural network for supplier ranking and classification for data filtering to reduce the information overload and enhance the negotiation ability of the agents. Besides, it would customize the information for users based on their interests.
