Authors: Li Fei , Huang Jia Jia , Peng Min , Cai Rui
Published: July 2013

Ranking has an extensive application in analyzing public opinions of social network (SN), such as searching the most hot topic or the most relevant articles that the user concerning. In these scenarios, due to the different requirements of users, there is need to rank the object set from different aspects and to re-rank the object set by integrating these different results to acquire a synthesize rank result.In this paper, we proposed a novel Feedback Ranking method, which lets two basic rankers learn from each other during the mutual process by providing each one's result as feedback to the other so as to boost the ranking performance. During the mutual ranking refinement process, we utilize iSRCC---an improvement on Spearman Rank Correlation to calculate the weight of each basic rankers dynamically. We apply this method into the article ranking problem on topic-query retrieval and evaluate its effectiveness on the TAC09 data set. Overall evaluation results are promising.

Published: July 2013

Ming association rules have been proved as an important method to detect intrusions. To improve response speed and detecting precision in the current intrusion detection system, this papers proposes an intrusion detection system model of MMFIID-DS. Firstly, to improve response speed of the system by greatly reducing search space, various pruning strategies are proposed to mine the maximal frequent itemsets on trained normal data set, abnormal data set and current data streams to establish normal and abnormal behavior pattern as well as user behavior pattern of the system. Besides, to improve detection precision of the system, misuse detection and anomaly detection techniques are combined. Both theoretical and experimental results indicate that the MMFIID-DS intrusion detection system is fairly sound in performance.
Temporal Transient Localization for Enhanced Pre-Echo Suppression
Authors: Ma Wen Hua , Xu Jin , You Yu Li
Published: July 2013

A specially designed short window of reduced effective size and other supporting windows, as used in a switched MDCT audio codec, are sequenced in such a way that this special window is placed around transient samples, thereby providing transient localization while leaving frequency resolution unchanged. Pre-echo is better suppressed because transient localization reduces thespread of both quantization noise and high bitrates associated with transients.The overheads include one or two additiona lbits and a short procedure, both for windows equencing, and more memory for storing additional window functions.

Authors: Chen Ji Wen , Zhang Jin Sheng , Yang Hong Juan
Published: July 2013

Knowledge modeling and solving strategy are the key techniques of improving the innovation design ability of a complex product with design knowledge system. Aiming at a formal expression of product behavior knowledge, generalized variables are introduced from the bond graph theory. The attributes of motion behavior are used to realize the unity of dynamic behavior and static behavior. The ontology model of product design function, behavior, structure knowledge is constructed with the six-tuple structure. With the breadth first search FBS ontology mapping strategy, product design is realized by searching within product design knowledge base according to the name similarity. For the new function introduced by new demand in product design, concept learning based on variant space is proposed to get the general function unit or special function unit. Then the innovation design is realized through FBS ontology mapping strategy. The validity of the proposed method is verified by example of innovation design of multi-wire diamond saw.

Authors: Li Cun He , Chen Rui Xue , Ouyang Yi Zhao
Published: July 2013

In classification, when the distribution of the training data between classes is uneven, the learning algorithm is generally dominated by the feature of the majority classes. Features in the minority classes are normally difficult to be fully recognized. Hyper-sphere support vector machine is an important method for unbalanced classification which is an important issue, but this algorithm has a defect. In order to significantly improve the classification performance of imbalanced datasets, we propose a new method based on Generalized Hyper-sphere Support Vector Machine to enhance the classification accuracy for the minority classes. Support vector machine (SVM) is then used as the base classifier to train the reprocessed dataset. Our experimental results demonstrate that the proposed selection technique improves the classification rate of the rare events, and it also improves the overall accuracy of SVM without data pre-processing.
Extraction of Purkinje Fiber Network from the Image
Authors: Li Jie , Wang Kuan Quan
Published: July 2013

The purkinje fiber network (PFN) is a very important conduction system in the endocardial surface of the ventricle, whose structure is crucial in ventricular physiopathologics. Traditional medical imaging methods, such as magnetic resonance imaging (MRI) or computed tomography (CT), fail to reveal the PFN information well. Another kind of method is to construct the PFN by the modeling method. i.e. modeling using the fractal structure of the endocardial surface photographs. However, among steps of the construction, PFN is extracted by the threshold value of the gray scale before the visualization, which needs the gray scale modification at some points to differentiate them from background points. In this work, we have proposed a semi-automated method for extracting PFN from the fractal structure in the left ventricle, which is proved to be feasible and efficient in the visualization and simulation of the heart, and is more adaptive to the extraction of the canine left ventricular purkinje fiber network from the fractal structure.

The micromixer device is modeled using artificial neural networks trained with finite element simulations of the underlying incompressible Navier-Stokes and mass transport PDEs. The neural networks design is based on a three layers perceptron with one input layer, one nonlinear hidden layer and one linear output layer. The neural networks can map the micromixer behavior into a set of analytical performance functions parameterized by the systems physical variables. The macromodel has been extracted from training output of the artificial neural networks. Three design variables, i.e., the flow velocity, the channel width, and the numbers of the mixing unit are selected for model design. The mixing index at the end of the serpentine channels is employed as the objective function. The macromodel has been validated with numerical simulations. It can be demonstrated that this macromodel should facilitate the design of microfluidic device with sophisticated channels networks.

Published: July 2013

We obtain necklace-pattern solitons (NPSs) from the same-pattern initial Gaussian pulse modulated by alternating azimuthal phase sections (AAPSs) of out-phase based on the two-dimensional (2D) complex Ginzburg-Landau equation with the cubic-quintic nonlinearity. The initial radially symmetrical Gaussian pulse can evolves into general necklace-rings solitons (NRSs). The number and distribution of pearls is tunable by adjusting sections-number and sections-distribution of AAPSs. In addition, we study the linear increased relationship between size of initial pulses and ring-radii of NRSs. Moreover, we predict the number-threshold of pearls in theoretical analysis by using of balance equations for energy and momentum. Final, we extend the research results to obtain arbitrary NPSs, such as elliptical ring, triangular-ring, and pentagonal ring.

Authors: Khlayboonme S.T. , Thowladda W.
Published: July 2013

The morphology, growth rate and atomic-bonding structure of nanocrystalline diamond films deposited on Si substrates were investigated under various pressures of the reactor. The films were deposited by CH4/H2 microwave plasma with two-step deposition and H2-plasma cleaning processes. The pressures of 1, 2, 5, 9, and 25 kPa were used for deposition. In situ gas-phase species, including electron density, were monitored by an optical spectrometer and impedance analyzer. The films were characterized by SEM, Raman microscope, and white light reflectrometer. When the pressure increased, the surface smoothness and diamond grain size increased, amorphous carbon content decreased, and the intensity ratio of CH/Hβ for the growth step increased. The growth rate was in proportional to the ratio of CH/Hβ for the nucleation step but in inverse proportion to the electron density. The growth rates decreased from 370 nm/h for 1 kPa to 320 nm/h for 2 kPa. After that, the growth rate rapidly increased to 460 nm/h for 9 kPa, but it gradually decreased to 450 nm/h for 25 kPa. The film refractive indices were 2.16 for 5 kPa, 2.21 for 9 kPa, and 2.38 for 25 kPa. The films grown under 1 and 2 kPa showed highly light absorption.

Published: July 2013

Fiber Reinforced Polymer (FRP) composites are used in many applications for their excellent strength-to-weight ratio. These properties are significant barriers for achieving the 3R concept (Recycle, Reuse, and Reduce). Inverse manufacturing is a recent technology that produces new materials and industrial goods from FRP waste based on life-cycle assessment (LCA), and it is expected to help solve the problems of 3R associated with FRP [1-. However, no effective recycling system of FRP has been established because of the cross-linked structure of thermosetting resin matrix and inorganic reinforcement fibers. To investigate the possibility of recycling and reusing both matrix and reinforcements, a project of preventing environmental deterioration was performed. In this study, a new decomposition method for recycling FRP waste by superheated steam was developed. Separation of the resin matrix and reinforcement fiber from the FRP was attempted, the FRP recycled from the separated fibers was remolded; this is called R-FRP.

Published: July 2013

Presently, with regard to the research in control of three-phase PWM-VSC under unbalanced dips, most of the literatures gain the current commands through the phase voltages based on the PQ power theory and the control flow is complicate too much. This paper, based on the instantaneous power analysis of VSC grid-side, calculate the current commands through line voltages and use the line voltages instead of the phase voltages in the feedforward. Not only the equation of current commands calculation is simplified, but also avoids the transformation of line voltages to phase voltages. In addition, this method adopts neither PLL nor coordinate transformation, and current sequential extraction is eliminated by adopting the PR controller in the current loop. In the end, the simulation results testify the efficiency of the proposed scheme in resisting grid voltage harmonics and nullifying fluctuation of dc-voltage.
