Let H={(z,t):z∈Cⁿ,t∈R^m} be the Heisenberg-type groups. For (z,t),(z′,t′)∈H, the group multiplication is given by (z,t)(z′,t′)=(z+z′,t+t′+12zJz′^t),where zJz′^t=(zU⁽¹⁾z′^t,zU⁽²⁾z′^t,…,zU^(m)z′^t), z′^t denotes the transpose of z′,and U^(j)(j=1,2,…,m) are real skew-symmetric orthogonal matrices. In this paper, we give the definition of the Radon transform on the Heisenberg-type groups, and obtain an inversion formula related with the mapping J by Fourier transform.

The process variables are sometimes imperfect in representing the observed process information about products or services. Fuzzy numbers are recommended to be used in above cases. We further improve a fuzzy Cumulative Sum (CUSUM) control chart, in which fuzzy data are viewed as a fuzzy random variable with a bootstrap distribution for the center and two spreads. A simulation example is given.

This paper firstly constructs a mixed exponential family distribution. Secondly,we employ the EM algorithm for the mixed exponential family distribution model under the normal stress life time test with full data or censored samples. Comprehensive literature then helps us get more general conclusions. Finally, the paper discusses a special mixed exponential family distribution parameters estimation through simulation.

Nanometer titanium dioxide (nano-TiO₂) removal of Tl(I) from aqueous solution and its preliminary mechanism were investigated by using the batch adsorption experiments. The adsorption of Tl(I) onto nano-TiO₂ decreased with the increase of solution pH. When the pH of solution was higher than the isoelectric point (6.0), the adsorption was fast and adsorption efficiency reached up to 99% at pH10. The adsorption of Tl(I) onto nano-TiO₂ reached equilibrium within 30 minutes and was fitted well by the pseudo-first-order model. Moreover, when the initial concentrations of Tl(I) in solution was 10~1 000 mg·L^-1, the adsorption was fitted well by the Langmuir isotherm and at temperature 288, 303, 318 K the maximum adsorption of Tl(I) onto nano-TiO₂ were up to 15.7,13.8,11.6 mg·g^-1, respectively. The value of ΔG and ΔH were negative during the adsorption, which showed that the adsorption of Tl(I) onto nano-TiO₂ was essentially an exothermic and spontaneous process. These results indicated that nano-TiO₂ could be a very promising adsorbent for removal of Tl(I).

In this work, ZnO/V₂O₅ core/shell nanotube arrays (NTAs) have been successfully synthesized via a simple and two-step electrochemical deposition process. The as-prepared ZnO/V₂O₅ samples are characterized by power X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The as-prepared ZnO/V₂O₅ NTAs exhibits enhanced photoelectrochemical (PEC) performance compared with pure ZnO nanorod arrays (NRAs), indicating the promising application in photoelectrochemical water splitting.

Naproxen is one of the important and effective nonsteroidal antiinflammatory drugs and widely used in pain and fever treatment. A novel chiral biphosphine ligands 6,6′-bis(diphenylphosphino)-5,5′-biquinoline (BIQAP) coordinate with Ru were successfully applied in asymmetric catalytic hydrogenation of 2-(6′-methoxy-2′-naphthyl)propenoic Acid in this paper. After a series of experiments, the results show that in the condition of 32 ℃, 10 MPa H₂, methanol as the solvent, the additive is Et₃N, Ru(R-BIQAP)(OAc)₂ as the catalyst. Optically pure naproxen with up to 81.7% enantiomeric excess were obtained in high yield (99%).

The activity against bacteria of flavonoids-propionic acid mixtures,different purity and different polar flavonoid from banana peel was studied by filter paper with Escherichia coli and Staphylococcus aureus. The results showed that the higher the purity of flavonoid was and the stronger the polarity was, the more powerful the antibacterial activity of flavonoid was. Antibacterial activity against gram positive bacteria Staphylococcus aureus was significantly greater than that against gram negative bacteria Escherichia coli. The minimal inhibitory concentration(MIC) of purified flavonoids on Staphylococcus aureus and Escherichia coli were 13.00 mg·mL^-1 and 3.25 mg·mL^-1. Flavonoids-propionic acid compound could increase antibacterial activity against Escherichia coli, both had synergistic effect.

The effects of different light intensity on growth and hydrochemical state of Misgurnus anguillicaudatus have been studied, M. anguillicaudatus were reared at different intensity light Ⅰ(0.1~10 lx), Ⅱ(10~100 lx), Ⅲ(100~1 000 lx)and Ⅳ(1 000~10 000 lx). Research findings are shown as follows:①The content of ammonia nitrogen increased at the beginning and then descended with the development of feeding. Within 30 days, the content of nitrite nitrogen inⅠ, Ⅱand Ⅲ gradually increased, whereas the content of nitrite nitrogen in Ⅳ light intensity increased at the beginning and then decreased;②The different light intensity significant impacts on daily food consumption, specific weight gain(SGR)and food efficiency(P<0.05).The daily food consumption of M. anguillicaudatus increased with the descending of light intensity, whereas when the light intensity reduced to Ⅱ, the daily food consumption of M. anguillicaudatus remained unchanged. The specific weight gain and food efficiency of M. anguillicaudatus showed negative linear relationship with light intensity.

Based on the established structural health monitoring system of He-dong Bridge, the simultaneous monitoring on the displacement and acceleration response at the main tower and bridge deck were conducted under ambient excitation for this bridge. The vibration displacements were measured by GPS deformation monitoring subsystem while acceleration responses were monitored by accelerometers. The improved HHT technique, which was based on EEMD method, was utilized to conduct the time-frequency analysis on GPS monitoring displacement. Meanwhile the ordinary peak pick-up method, which is based on the normalized power spectral density, was also adopted for modal parameter identification with measured acceleration signals. Compared results from two different identification methods showed the more advantage in the improved HHT method, as it could deal with the interference of non-stationary random signal in low frequency and reduce the incidence of the modal mixture effectively. Meanwhile comparison with finite element numerical analyzed results implied that identified modal parameters for this bridge from both HHT and peak pick-up methods are reliable. The combination of GPS deformation monitoring system and vibration acceleration test system could identify the modal parameter of He-dong Bridge effectively and could provide a solid basis for improving the bridge operation safely.

This paper first introduces the dynamic equation of fluid-solid coupling, followed by numerical simulation using ACTRAN software on the vibration of the cable structure acoustic radiation problem. Finite element method is used to define different monitoring loading infinity and analyze the relationship between the sound radiation and vibration amplitude. Results show that vibration and sound radiation has a proportional relationship, namely when the vibration is severe, the sound pressure of the corresponding mechanical parts is high; when the vibration is small, the corresponding sound pressure is low. Furthermore, a cracked structure presents high vibration amplitude and the sound pressure value is higher than the healthy structure. This study provides the theoretical foundation for the intelligent fault diagnosis of mechanical equipment research using acoustical signals.

We model and analyze the OAuth authorization process based on an open platform instance in China. The analysis is on the combination of protocol specification and real network traces with using the Alloy language. We focus on the addressed security problems. By using the Alloy analyzer, we find a vulnerability that could be exploited to a man-in-the-middle attack. We give a proof of concept exploitation in real applications. We further discuss some other open platforms with similar experiments and propose a solution to this problem.

Based on the Statistical Yearbook of Guangzhou’s energy consumption statistics, the paper has analyzed dynamics of the industrial structure in Guangzhou since 1978. Energy consumption from 2000 to 2010 is explored and carbon emission is estimated for three industries and several main sectors of secondary industry. Results show that Guangzhou’ development has moved into postindustrial economy. When it comes to energy consumption, energy intensity, carbon consumption or carbon intensity, secondary industry owns higher value than primary or tertiary,especially in papermaking and paper products within light industry, electricity and heat product and supply within heavy industry. However, carbon emission should be paid more attention to in both primary and tertiary industries. It is pointed out that further innovation and optimization for local secondary industry is necessary. And those sectors which have higher values of energy consumption, energy intensity, carbon consumption and carbon intensity should be more concerned about. Meanwhile, industrial structure and technology should be pressed ahead to optimize and upgrade within both primary and tertiary industries. Finally, some suggestions on urban development toward sustainability are put forward.

At present, industrial development and structural incoordination of the talent development in China is becoming more and more prominent, which is mainly concerned with the unreasonable organization model of industrial talent development in our country. According to a four-dimensional analysis framework of industry talent development organization: Environment-elements-structure-function, the paper makes comparative analysis between China and America, and judges comprehensively the industry talent development organization in America belongs to super triple helix, while the industry talent development organization in China is double spiral model. Finally, drawing on the experience from American development and considering the actual situation of our country, the paper proposes improvable proposals: boost the evolution of industry personnel development organization mode in two stages, adhere to the reset and promotion of super triple helix mode under current economic system; the development of industry association and triple helix interface organization; stakeholders actively participate in and implement the interests fit; three-level hierarchical coordination control based on decentralization of the higher education.

Shopping has highest elasticity of demand and supply in tourism industry, which plays an important strategic role in the development of Chinese tourism economy for the future. Integrating advantage of Expectation-Perception, Performance-Only and Congruity model, this paper built tourism shopping satisfaction model with universal applicability and consistency. On the basis of the new model, we compare three cities in demand characteristics and tourist shopping satisfaction by separating the tourist into three source markets. Research results show that the inbound tourists pay more attention to personalized service and service quality. Domestic tourists focus on the price. Guangzhou is the most competitive in shopping but should improve the service quality, on the other hand, shopping in Zhuhai is not cost-effective enough, lacking attraction of domestic tourists; Shenzhen needs differentiation through improving “tourist shopping experience” to narrow the gap with Hong Kong.
