Published: February 2011

A hybrid fiber optically powered current transformer with the Hall element is studied and developed in this paper. The sensing probe is the zero-flux current transformer which is based on Hall Effect. The main current can be insulated from the measurement circuit by use of Hall current transformer. Due to the broad bandwidth characteristics and the high linearity between the Hall potential and measured magnetic flux density and the high sensitivity of the Hall current transformer, any changes in the excitation current can be accurately detected without distortion. The three-dimensional model of the Hall current transformer is set up by use of ANSYS software in this paper. The magnetic flux density in the opening air-gap is calculated by nonlinear magnetic analysis method of the three-dimensional finite element. Experimental data shows that the calculation method and results are reliable. At the same time, high power laser power supply is adopted to drive the electronic devices in high potential side, and the reliable insulation between the high potential and low potential is achieved by optical fibers. So the accuracy of this measurement system can be ensured.

Published: February 2011

In view of the defect that network DEA (data envelopment analysis) can not reflect the network structure when it comes to dynamic evaluation, we proposed a two-stage evaluation method of dynamic network DEA. Time parameter was introduced to network DEA and dynamic network DEA model was established. In order to evaluate the efficiency of dynamic network DEA in several time spans, we built a two-stage evaluation method. In the first stage, dynamic network DEA efficiency matrix was formulated. In the second one, a new input-output DEA unit was set up to evaluate the synthetical efficiency of dynamic network DEA. The two-stage method can manifest the real dynamic property in network DEA, as well as consider the network structure which involves intermediate products by dynamic measure. A numerical example indicated that the two-stage evaluation method can solve dynamic network DEA problem efficiently, it can also provide improved information between inefficient DMU and optimum values by slacks. The new measure can be a good tool of systems analysis.

Published: February 2011

The analysis of codon usage may improve our understanding of the evolution and pathogenesis of DEV（Duck enteritis virus） and allow reengineering of target gene to improve their expression for gene therapy.In this study,we calculated the codon usage bias in DEV UL55 gene and performed a comparative analysis of synonymous codon usage patterns in other 26 related viruses by EMBOSS CUSP program and Codon W on line.Moreover,statistical methods were used to investigate the correlations of these related parameters. By comparing synonymous codon usage patterns in different viruses,we observed that synonymous codon usage pattern in these virus is virus speciﬁc and phylogenetically conserved, with a strong bias towards the codons with A and T at the third codon position. Phylogenetic analysis based on codon usage pattern suggested that DEV UL55 gene was clustered with the avian Alphaherpesvirus but diverged to form a single branch. The Neutrality-plot suggested GC12 and GC3s adopt the same mutation pattern,meanwhile,the ENC-plot revealed that the genetic heterogeneity in UL55 genes is constrained by the G+C content, while translational selection and gene length have no or micro effect on the variations of synonymous codon usage in these virus genes.Furthermore, we compared the codon preferences of DEV with those of E. coli, yeast and Homo sapiens.Data suggested the eukaryotes system such as human system may be more suitable for the expression of DEV UL55 gene in vitro. If the yeast and E. coli expression system are wanted for the expression of DEV UL55 gene ,codon optimization of the DEV UL55 gene may be required.

Published: February 2011

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.

Published: February 2011

With Multi-channel MAC protocols, transmission pairs can send data packet simultaneously. Hence, higher network throughput can be achieved. The developing of 802.11s standard provides the power saving model multi-channel MAC protocol (PSM-MMAC) framework, which divides into negotiation phase and data phase. All the users select appropriate channels to transmit data in dedicated channel during negotiation phase, then the users will switch the transceivers to the selected channel to transfer data packet by RTS/CTS handshake. While taking the size of data window constraints, therefore how to design the data packet size is the key issue of PSM-MMAC in saturation network case. In this paper, we propose a new policy that can adjust the size of data packet based on the channel occupancy and the fairness of user access for unsolicited Grand Service, which has strict requirements on the delay jitter and maximum reserved traffic rate. We also develop the probabilistic statistical analysis model to compare the performance of previous policy and our proposed policy. Simulation results verify our analysis model, and show our policy has the superior performance of the PSM-MMAC to the previous scheme.

We may get the global optimal solution though pre-processing of using the thought of the branch and bound algorithm and forcing rules. Then the original problem changes into a smaller multi-user detection problem, in order to get the aim of reducing MAI, increasing the probability of a correct decision and reducing the bit error rate. From the simulation experiment results, it is shown that it has a significant effect in system detection, because after pre-processing the probability of a correct decision has increased, and the bit error rate has been reduced.

Published: February 2011

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.

The mudstone is formed under the special environment with soft-hard alternant strata in Nanning Basin . The composition,engineering and mechanical properties have a certain complexity and specificity,so the parameters of the mudstone are discrete and variable by which the strength characteristics are influenced. According to the problem of the strength of mudstone,the influence factor is analysed on the strength of mudstone with soft-hard alternant strata in Nanning Basin through the composition, stress history, geological environment, water-rock interaction and disturbance, etc.. The analysis shows that in the final analysis the reduction of the mechanical properties of mudstone is due to structural damage, stress weakening and energy weakening.And the measures of improving the bearing capacity of mudstone are discussed from the test methods, construction control measures, in situ testing and engineering design.

Authors: Sun Ning , Liang Yin Xing , Tong Zhen
Published: February 2011

The properties of the fiber material, which prepared from the high-performance heterocyclic polymer poly-p-phenylene-benzimidazole-terephthalamide (PBIA), were investigated. Poly-m-phenylene isophthalamide (PMIA) and poly-p-phenylene terephthalamide (PPTA) fibers were also studied, for comparison, under the same experimental conditions. Thermogravimetry(TG) and thermogravimetry coupled to Fourier transform infrared spectroscopy(TG-FTIR) were used to study the properties of these fibers. The results show that PBIA fiber has better tensile properties, thermal stability than that of PMIA and PPTA fibers. The onset degradation temperature of PBIA is the highest, namely 421°C in nitrogen. TG-FTIR provides information on the compositions of the pyrolyzates as well as their relationship to the structures of the polyamides. Analysis of the results indicates that a hydrolytic mechanism plays a leading role at lower temperature, and a homolytic mechanism is dominant at higher temperature.

Published: February 2011

The aim of this paper is mainly to study the main coal-dust pollution sources in the coal preparation plants of Ping Shuo Branch of China National Coal Group. Through the combination of many measurement data with numerical simulation of gas-solid two-phase flow, dust precipitation mechanisms have been gained for the feeder in Ping Shuo Coal Preparation Plant. Dust pollution of the feeder is caused by the positive pressure of the induced feeding wind-flow and the bad seal itself. Firstly, the durable flexible seal material is used to seal up the feeder. Secondly, the seal guide-chute with the dust collector is installed on the belt. Finally, the air volume and the pressure of the dust collector are determined by means of numerical simulation, and the reasonability of the plan is explained from the angle of the dust control mechanism. The main technical parameters of the dust control plan, such as the seal guide-chute length, and the air volume and the pressure of the dust collector, are determined through the numerical simulation. The simulation result and the actual result verify the above dust control plans. The study methods and results provide a guide for the dust control in a certain similar business.

Published: February 2011

The removal of diesel exhausts by non-thermal plasma technology has been investigated focused on the simulation gas experiment at atmospheric pressure and room temperature for many years. However, the research for real diesel engine is need to be further studied. In the experiments, a non-thermal plasma (NTP) reactor was designed based upon dielectric barrier discharge. NO/NO2 conversion was studied as a function of the specific input energy (SIE) by varying the frequency and voltage applied on the NTP reactor through bench test. Results showed that NTP SIE was increased with the voltage at each frequency. The conversion of NO to NO2 was increased at higher NTP SIE. However, NO will further be converted to other active species but not only NO2.
