Shenyang University of Chemical Technology is a university in Shenyang, Liaoning, China under the provincial government. Shenyang University of Chemical Technology, partially run by the state and mainly by the local government, is an institute of mainly in science, specialization and advantage in the field of chemical industry, integration in the field of science, engineering, economy, management and arts.In 1952, Shenyang Chemical Industry Technical School was established. In 1958 it was upgraded to a college and renamed Shenyang Institute of Chemical Technology. In 1960, renamed to Liaoning University of Science and Technology. In 1962, back to Shenyang Institute of Chemical Technology. January 21, 2010, was renamed Shenyang University of Chemical Technology. In near future, its name is going to be change to Shenyang University of science and Technology.Now it has become the multi-levels teaching system for postgraduates, undergraduates, and the education of Branch Institute , foreign students, adults, and continuous education.

In this paper, we reported that the prepared nickel coated carbon nanofibers (NiCNFs) by electroless plating method exhibited superior catalytic effect on hydrogen absorption/desorption of magnesium (Mg). It is demonstrated that the nanocomposites of MgH2/5 wt.% NiCNFs prepared by ball milling could absorb hydrogen very fast at low temperatures, e.g. absorb ∼6.0 wt.% hydrogen in 5 min at 473 K and ∼5.0 wt.% hydrogen in 10 min even at a temperature as low as 423 K. More importantly, the desorption of hydrogen was also significantly improved with additives of NiCNFs. Diffraction scanning calorimetry (DSC) measurement indicated that the peak desorption temperature decreased 50 K and the on-set temperature for desorption decreased 123 K. The composites also desorbed hydrogen fast, e.g. desorb 5.5 wt.% hydrogen within 20 min at 573 K. It is suggested that the new phase of Mg2Ni, and the nano-sized dispersed distribution of Ni and carbon contributed to this significant improvement. Johnson-Mehl-Avrami (JMA) analysis illustrated that hydrogen diffusion is the rate-limiting step for hydrogen absorption/desorption. © 2009 Professor T. Nejat Veziroglu. Source

Structural relation patterns have been introduced recently to extend the search for complex patterns often hidden behind large sequences of data. This has motivated a novel approach to sequential patterns post-processing and a corresponding data mining method was proposed for Concurrent Sequential Patterns (ConSP). This article refines the approach in the context of ConSP modelling, where a companion graph-based model is devised as an extension of previous work. Two new modelling methods are presented here together with a construction algorithm, to complete the transformation of concurrent sequential patterns to a ConSP-Graph representation. Customer orders data is used to demonstrate the effectiveness of ConSP mining while synthetic sample data highlights the strength of the modelling technique, illuminating the theories developed.

Principal component analysis (PCA) has been widely applied in process monitoring and modeling. The time-varying property of industrial processes requires the adaptive ability of the PCA. This paper introduces a novel PCA algorithm, named on-line PCA (OLPCA). It updates the PCA model according to the process status. The approximate linear dependence (ALD) condition is used to check each new sample. A recursive algorithm is proposed to reconstruct the PCA model with selected samples. Three types of experiments, a synthetic data, a benchmark problem, and a ball mill load experimental data, are used to illustrate our modeling method. The results show that the proposed OLPCA is computationally faster, and the modeling accuracy is higher than conventional moving window PCA (MWPCA) and recursive PCA (RPCA) for time-varying process modeling. © 2011 Elsevier B.V.

For the purpose of improving to redundancy of the transmission path, compensating for poor communication quality of wireless communication in harsh industrial environments and partly improving reliability of industrial wireless networked control system (WNCS), the multi-path transmission mechanism based on topology of dual-band and secondary structure is proposed. The topology of dual-band and secondary structure allows use of independent frequency bands to communication on devices and communication controllers. So as to diminish the chance of conflict and the effective use of space capacity to work in parallel. It partly eased real-time problems on wireless communication technology in industrial environment. At the same time, we introduce to DS-UWB in WNCS firstly. The project of PROFIBUS integrated with UWB are designed on the multi-path transmission mechanism based on topology of dual-band and secondary structure. It provides an effective application way of the multi-path transmission mechanism. © 2010 IEEE. Source

Mesoporous MnO2-Fe2O3-CeO2-TiO2 was prepared with sol-gel method and demonstrated to have good low-temperature activity and sulfur-poisoning resistance for selective catalytic reduction (SCR) of NO with NH3 in SO2-containing gases. In comparison with this, the catalyst with the same composition but made according to the conventional impregnation method exhibited obviously lower SO2-poisoning resistance and selectivity to the formation of N2 in the SCR reactions. FTIR analysis of the spent catalysts after SCR reactions for 16 h and 60 h in a SO2-contaning gas demonstrated that there was little difference in the amount of deposited ammonium sulfate over the mesoporous catalyst between the two cases. The mesopore channels existing in the mesoporous catalyst enabled probably a dynamic balance between the formation and decomposition of ammonium sulfate in SCR reactions. This concern was justified through comparing the N2 adsorptions and XPS spectra for the catalysts made with the impregnation and sol-gel methods. The article clarified as well the facilitation effects of introducing Ce and Fe into the mesoporous catalyst on activity, selectivity and SO2-poisoning resistance. Crown Copyright © 2009. Source
