    Abstract: The research of structural-deformed coal is important in coalbed methane exploitation. Compared with those of undeformed coals, the geophysical logging characteristics of structural-deformed coals show lower amplitude value of deep lateral log (LLD) and density log (RHOB) and higher amplitude value of acoustic log (AC). In the southern Shizhuang Block, the structural-deformed coal is commonly developed, with the thickness ranging from 0.6 to 1.1 m. The thickness of structural-deformed coals accounts for 11.5-18.5% of the total coal thickness. In general, the structural-deformed coals are more developed in the west than those in the east of the study area.

    Abstract: A novel method of vehicle type recognition based on template matching is proposed to improve the real-time performance of the vehicle type recognition in real traffic scenes. GRM is applied and the template is normalized for realizing parallel template matching. Then, we realize the rapid vehicle type recognition through lookup tables by the hierarchical index of vehicle type template with k-means clustering and size normalization processing. The results show that the algorithm can recognize vehicle type in traffic scenes efficiently.

    Abstract: A redox polymer, poly(ethylenimine)ferrocene (PEI-Fc) was synthesized by attaching ferrocene groups to the backbone of water soluble poly(ethylenimine), and multilayer film in nanoscale was assembled on gold electrode by alternate layer-by-layer adsorption (LBL) of the positively charged PEI-Fc and the negatively charged thermostable diaphorase (DI) from B.Stearothermophilus. The LBL process was monitored and analyzed by quartz crystal microbalance (QCM) technique, which confirmed the formation of the multilayer structure. The electrochemical oxidation of coenzyme (reduced nicotinamide adenine dinucleotide, NADH) was observed on the electrode fabricated with PEI-Fc/DI multilayer film, and the influence of layer number on current response was investigated. The modified electrode retained ca. 65% relative response after storage in buffer for two months and 50% relative response after incubation at 80 °C for 3 min, which inferred that the multilayer structure was unique stable. A NAD-dependent glucose-6-phosphate dehydrogenase (G6PDH) was also immobilized via the same LBL technique, and electrode modified with PEI-Fc/DI/G6PDH film exhibited current response to glucose-6- phosphate in the presence of free NAD+.

    Abstract: The structural comfort of long-span floor structure which setup stadium is studied in this paper. The measured spectrum is used to simulate human movement loads. All possible loads are considered and key parameters about structural comfort of the long-span floor structure are analyzed, and then, the comfort of athletes in match and audiences on the stadium stand are analyzed. The results show the vertical acceleration and natural frequency of structure are decreased approximate linearly with increasing of the slab thickness; take one engineering project for example, according to the method proposed in this paper, the different structural comfort control index should be adopted in sports field and audience stand, respectively. Comprehensive and system design references of load simulation, pre-stressed structure dynamic analysis, comfort performance index and control standards are offered in this paper for long-span pre-stressed steel floor structure project that used for stadium.

    Abstract: Low-carbon development has been well recognized as a strategic option for the transformation during the socio-economic development in China. As a symbol of highest level of research and development, high-tech eco-industrial parks are playing an important role in response to climate change and the trend of low-carbon development, to maximize the low-carbon development potentials and bridge a unique and feasible solution to low-carbon development. This paper explored the factors affecting the development of high-tech eco-industrial parks using Logarithmic Mean Weight Division Index (LMDI)index analysis and Kaya equation, and summarized these factors as economic growth, industrial structures, energy efficiency, energy structures and carbon emission coefficients.

    Abstract: According to the structural characteristics of cuprous chloride ions in the wastewater, we use respectively rhodamine-B and 8-hydroxyquinoline as extractant to perform an extraction experimental research for cuprous chloride wastewater. We examine the influence of extraction time, extractant concentration, phase ratio, and pH on the disposal efficiency. We obtain the following observations: The usage of 8-hydroxyquinoline and rhodamine-B as the extractant can extract copper from cuprous chloride wastewater to some extent. Reducing pH of cuprous chloride wastewater solution with concentrated sulfuric acid is not conducive to 8-hydroxyquinoline extraction, which is conducive to rhodamine-B extraction but the effect is not obvious. Increasing temperature is conducive to 8-hydroxyquinoline extraction but not conducive to rhodamine-B.

    Abstract: This article selects GCr18Mo steel to make an inner ring of rolling bearing. After isothermal quenching heat treatment, microstructure and mechanical properties are tested. The results show that microstructure and hardness from the surface to the core is uniform. The compositions are lower bainite and carbide, and both of them are small. The length-width ratio of lower bainite needle is about 10, and the average diameter of carbide in is 0.33μm. The hardness ranges from the surface to the core is between 715 HV and 755 HV, the average hardness of the inside and outside surface is 59.9HRC. Stress state of the surface is compressive stress and axial compressive stress is greater than the one of the hoop. Compressive stress in axial direction is about 588MPa, which is about 390MPa in the direction of the ring. After polishing, compressive stress in axial direction is about 483MPa, which is about 231MPa in the direction of the ring.

    Abstract: Through the experiment of different Irrigation Amounts with urea applied, the paper studied the influence of Irrigation Amounts on soil nitric nitrogen dynamical changes under film hole irrigation and the nitric nitrogen content of the growing period was determined. The result showed: different irrigation amount in the profiles being 3cm and 8cm away from the film hole center, it appeared nitric nitrogen accumulation peaks, increased the irrigation amount promoted the transformation of urea, increased the transformed nitric nitrogen content and distribution of nitric nitrate and the risk of nitric nitrate leaching. In the profiles being 3cm away from the film hole center, the nitric nitrogen accumulation peak significantly reduced at harvest stage, but it reduced in the profiles being 8cm away from the film hole center at milky stage. The milky stage was the maximum period when the corn uptook nitrogen at different irrigation amount. Increased irrigation amount lower the accumulation content of nitric nitrogen near the film hole center after harvest, and higher the accumulation content of nitric nitrogen far away from the film hole center. Above researches could provide the basis for rational fertilization of farmland and nitrate environmental impacts on assessment.

    Abstract: Multirate and DFT based fast parallel algorithm for the 2-D inverse discrete Gabor transform (IDGT) is presented. A 2-D synthesis filterbank is designed for the 2-D IDGT. The parallel channels in the filterbank have a unified structure and can apply the 2-D fast inverse discrete Fourier transform (IFFT) algorithm to reduce the computational load. The computational complexity of each parallel channel is very low and is independent of the oversampling rate. Thus, the proposed parallel algorithm is attractive for real time image processing.

    Abstract: Novel and fast algorithm for the multirate and parallel implementation of the 2-D DCT-based real-valued discrete Gabor transform (RDGT) is presented. A 2-D multirate-based analysis filterbank is designed for the 2-D RDGT. Each of the parallel channels in the filterbank has a unified structure and can apply the 2-D fast discrete cosine transform (DCT) algorithm to reduce its computational load. The computational complexity of each parallel channel is very low and is independent of the oversampling rate. All the RDGT coefficients are computed in parallel during the analysis process. Thus, the proposed parallel algorithm is attractive for real time image processing.
