Authors: Qiu Dong , Dai Wen Juan
Published: August 2014

AOD furnace Smelting Ferrochrome is a complex process. The discretion of the impurity content of phosphorus is one of the important factors affecting the quality of ferrochrome products. If ferrochrome phosphorus excesses, the product is easy to break. At present, the most detection methods of determination the end phosphorus content are artificial experiments, so efficiency is lagging behind. It is necessary to establish a model to predict end-point phosphorus content for improving production efficiency, reducing costs, saving energy consumption. The important influence factors of AOD furnace smelting ferrochrome end-point phosphorus content were determined based on analyzing response characteristics of hot metal dephosphorization pretreatment and thermodynamic condition, the control variables of the end phosphorus content were fixed. According to Sinosteel Jilin Ferroalloys Co., Ltd 5t AOD furnace smelting medium-low carbon ferrochrome technology and production data, a prediction model for AOD furnace smelting ferrochrome end-point phosphorus content has been established based on RBF artificial neural network in accordance with the ferrochrome smelting process for online prediction of end-point phosphorus content. Results showed that the prediction precision of target shooting is 85.7% within the error 0.003%, which has provided important theoretical basis on improving the smelting process and product quality.

Published: August 2014

In this study, the effect of bond thickness upon shear strength and fracture toughness of epoxy adhesively bonded joint with dissimilar adherents was addressed. The bond thickness, t between the adherents was controlled to be ranged between 0.1 mm and 1.2 mm. Finite element analyses were also executed by commercial ANSYS 11 code to investigate the stress distributions within the adhesive layer of adhesive joint. As a result, shear strength of adhesive joint reduces with increasing bond thickness. The strength of shear adhesive joint was also depended on elastic modulus of adherent. Moreover, the failure of dissimilar adherents bonded shear joint originated at a location with critical stress-y which was the interface corner of ALYH75/epoxy. In the case of shear adhesive joint with an interface crack, the fracture also occurred at the ALYH75/epoxy interface even in the steel-adhesive-aluminum (SEA) specimens. Fracture toughness, Jc of aluminum-adhesive-steel (AES) joints was similar to those of SES and demonstrates strong dependency upon bond thickness. Furthermore, the interface crack in SEA specimen has relatively large fracture resistance if compared to those in AES specimen. Finally, Kc fracture criterion was found to be appropriate for shear adhesive joints associated with adhesive fracture.

Cyclic Cohesive Zone Model for Simulation of Fatigue Failure Process in Adhesive Joints
Authors: Johar Mahzan , Kosnan Mohamad Shahrul Effendy , Tamin Mohd Nasir
Published: August 2014

Progressive failure process of adhesive joint under cyclic loading is of particular interest in this study. Such fatigue failure is described using damage mechanics with the assumed cohesive behaviour of the adhesive joint. Available cohesive zone model for monotonic loading is re-examined for extension to capture cyclic damage process of adhesive joints. Damage evolution in the adhesive joint is expressed in terms of cyclic degradation of interface strength and stiffness. Mixed-mode fatigue fracture of the joint is formulated based on relative displacements and strain energy release rate of the interface. A power-law type variation for each of these cohesive zone model parameters with accumulated load cycles is assumed in the presence of limited experimental data on cyclic interface fracture process. The cyclic cohesive zone model (CCZM) is implemented in commercial finite element analysis code and the model is validated using adhesively bonded 2024-T3 aluminium substrates with epoxy-based adhesive film (FM73M OST). The CCZM model is then examined for cyclic damage evolution characteristics of the adhesive lap joint subjected to cyclic displacement of Δδ = 0.1 mm, R=0 so as to induce shear-dominant fatigue failure. Results show that the cyclic interface damage started to initiate and propagate symmetrically from the both overlap edges and degradation of interface strength and stiffness started to accumulate after 0.5 cycles of displacement elapsed. The predicted results are consistent with the mechanics of relatively brittle interface failure process.

Published: August 2014

ZnO nanosheetlike structures were synthesized on zinc (Zn) foil substrates by electrochemical deposition method in ZnCl2 aqueous solutions at a temperature of 90 °C. In addition, the synthetic parameters in this work allow additional structural direction for ZnO nanoscaled structures. The morphology growth from smooth plane structures to nanosheet like structures could be accomplished by modifying the current densities of electrodeposition. In the photoluminescence (PL) spectra of the as-synthesized ZnO samples, typically there are few oxygen vacancies or interstitial Zn centers would be produced when the electrochemical deposition was performed out with a low current density. The UV peak is usually considered as the characteristic emission of ZnO nanosheetlike structures and attributed to the band edge emission or the exciton transition. All XRD diffraction peaks of ZnO nanosheetlike structures are shown in a good agreement with hexagonal structure. The average particle size was calculated using the Debye-Scherrer formula. ZnO nanosheetlike structures processed for various current densities have different size.

The aim of this study is to investigate the feasibility of incorporating chitosan solution in fibrous filter media made from lignocellulosic biomass. The wet lay-up method was adopted for filter media fabrication. Diluted acetic acid was used as medium to dissolve the chitosan powder. Chitosan solution was applied to the fiber using two different deposition techniques, namely, spray method and addition method. The tensile test demonstrated that the filter media using spray method outperformed a filter media made from by addition technique. From the FT-IR spectrum, when the chitosan was added to empty fruit bunches fibers, the absorption peaks at around 1642 cm-1 are clearly identified that showing the presence of amine group in the fibers. The changes observed in the spectra indicated the possible interaction of functional groups between chitosan and cellulose in the fibers. The newly developed non-woven filter media integrates the functions for both the deep filtration and mechanical screen, thus it will be an alternative medium in oily wastewater treatment industry.

The handwritten test samples and noise corrupted samples are finally inputted into the network to verify its recognition performance. Simulation results reveal that DHNN has good fault tolerance and disturbance rejection performance. In addition, the recognition system is realized with MATLAB neural network toolbox and GUI, which verifies the feasibility of the algorithm.

Based on the assumption of plane section, ideal elastic-plastic model of steel and the constitutive relations of concrete in Chinese Code for Design of Concrete Structures, numerical method is used to analyze the relationship of the axial force-moment-curvature on RC section. After dividing the normal section into strips, we adopt the secant stiffness iteration method (according to the results of each iteration, modify the secant stiffness through changing the elastic modulus of materials) to compile computer program. The results of the paper show a good agreement with those of the analytical method. Comparing with the analytical method, the numerical method of the paper can be wildly used in the application.

Authors: Wu Yang , Zhao Ting Di
Published: August 2014

As increasing in the number of elements and the complexity of their interactions, fault prognostics faces real challenge to predict faults in a complex system. System fault regularly results from the interaction of component faults performing as logical and timing relationships. We use Bayesian Net to evaluate these logical relations. And the other section of system faults concerns about time sequence of those component faults. Thence, this Bayesian method is expanded to Time Bayesian Net in order to solve this kind of problem. Component fault prognostics is the basis, running dates derived from sensors are applied to analyze status of components in real time. Then a traditional Bayesian Net is constructed according to the mechanism and logical structure of the system. Followed by, exploiting the conclusion from interaction analysis of components, this net is built as a Time Bayesian Net. Afterward, Timed Bayesian Net receives inputs from the outcomes of component fault prognostics, and predicts the type of fault and its time of occurrence through Bayes’ rules.

Authors: Li Fa Chao , Yin Jian Ning
Published: August 2014

Nowadays there are two kinds of tools which are widely used in uncertain information processing, namely, the fuzzy sets theory and fuzzy roughness sets theory. Besides, how to construct a fusion method for the two kinds of uncertain information systematically has been a focus in both academic and applied fields. In this paper, we put forward the concept of level effect function, and analyze the characteristics of a kind of level effect function. Furthermore, we present the fuzzy roughness degree measurement model based on level effect (FRD-BLE), by combining with the roughness measurement method of level cut set. All the results indicate that FRD-BLE has good structural characteristics and interpretability both in theoretical analysis and practical applications. It can be easily apply the fuzzy processing consciousness into decision-making system with the aid help of FRD-BLE.
Anti-Occlusion Algorithm for Object Tracking Based on Multi-Feature Fusion
Authors: Cao Jie , Liang Xuan
Published: August 2014

Complex background, especially when the object is similar to the background in color or the target gets blocked, can easily lead to tracking failure. Therefore, a fusion algorithm based on features confidence and similarity was proposed, it can adaptively adjust fusion strategy when occlusion occurs. And this confidence is used among occlusion detection, to overcome the problem of inaccurate occlusion determination when blocked by analogue. The experimental results show that the proposed algorithm is more robust in the case of the cover, but also has good performance under other complex scenes.

Authors: Liu Wei Jian , Xiao Si Da , Yao Ruo He
Published: August 2014

In this paper, we propose a new super-resolution algorithm based on wavelet coefficient. The proposed algorithm uses discrete wavelet transform (DWT) to decompose the input low-resolution image sequences into four subband images, including LL, LH, HL, HH. Then the input images have been processed by the 3DSKR (Three Dimensional Steering Kernel Regression) super resolution (SR) algorithm, and the result replaces the LL subband image, while the three high-frequency subband images have been interpolated. Finally, combining all these images to generate a new high-resolution image by using inverse DWT. Proposed method has been verified on Calendar and Foliage by Matlab software platform. The peak signal-to-noise (PSNR), structural similarity (SSIM) and visual results are compared, and show that the computational complexity of the proposed algorithm decline by 30 percent compared with the existing algorithm to obtain the approximate results.

Published: August 2014

This paper demonstrates methods to recognize 3D designed features for virtual environments and apply them to Virtual assembly. STEP is a standard of Product data Exchange for interfacing different design systems, but it cannot be used as input for virtual environments. In order to use feature data in virtual assembly environments, main data source from a STEP file should be recognized and features should be re-built. First, Attributed Adjacency Graph (AAG) is used to analyze and express the boundary representation; second, a feature-tree of a part is constructed; third, using the AAG and feature-tree as inputs, we analyze and extract of features with a feature recognition algorithm; finally, various levels of detail of object geometric shapes is built and expressed in XML for virtual assembly applications.
