Abstract: An eddy current excitation signal source was designed based on the linear control theory. By analyzing the interference and characteristics of signal source, a multi-input-single-output (MISO) feedback control system was designed and created using a lock-in amplifier, and an eddy current sensor was applied in the feedback loop of the system. As a result, the noise in the loop circuit was suppressed; this resolved the current instability problem in eddy current sensor. Furthermore, a mathematical model was established, and the stability and bandwidth of the system were verified by simulations. Compared with the traditional signal sources, experimental results show that this signal source had steadier current output, smaller temperature drift and stronger load capability. Therefore, the foil thickness measurement based on this signal source had a very high accuracy. ©2015 SPIE.

Abstract: We performed Brownian dynamics simulations of a single polymer with monomer diffusion biased in a field of constant activation forces. We compared coil shapes among the synchronous and non-synchronous (random and sequential) updating schemes of monomer positions. The synchronous scheme makes an ideal linear integration of monomer motions, while the random scheme mimics the real nonlinear situation holding dynamic heterogeneity along the polymer chain, and the sequential scheme represents its extremely inhomogeneous situation. We found that, in contrast to the synchronous scheme that raises no deformation, the sequential scheme accumulates the local acceleration generated by dynamic heterogeneity and reveals a 'cracking-the-whip' effect along the chain from one end to the other to stretch the polymer coil. Meanwhile, the random scheme accumulates the local acceleration towards the middle segment of the chain and thus raises an internal tension for coil deformation as well. Our results demonstrate the dynamic heterogeneity source of coil deformation on biased polymer diffusion, which implies a molecular-level nonlinear factor in the non-Newtonian-fluid behaviors of polymer flows. © 2014 Society of Chemical Industry.

Abstract: This paper examines the multi-objective morphology optimization of free-form cable-braced grid shells. First, according to the shape forming method for grid shells, shape optimization can be realized by adjusting the generatrix and directrix rather than optimizing the whole surface. Second, the multi-objective shape optimization of free-form cable-braced grid shells is conducted. According to different practical requirements, the mechanical and geometric indexes, mechanical and economic indexes, or different mechanical indexes are used as multiple optimization objectives. Four main conclusions can be drawn from this study. First, with the above shape optimization method, the optimized surface does not change significantly; therefore, this method is useful in the shape optimization of grid shells with given initial surfaces. Second, among the static mechanical performance indexes, the mechanical behavior of the cable-braced grid shell is better with strain energy as the optimization objective. Third, with the weight of steel tubes and strain energy as the optimization objectives, the result of the multi-objective optimization that combines section optimization with shape optimization is favorable and practical in engineering applications. Fourth, when strain energy and the variance of the tube lengths are used as multiple optimization objectives, the structural mechanical behavior is not sensitive to the weight factor of variance of the tube lengths. © 2015, Korean Society of Steel Construction and Springer-Verlag Berlin Heidelberg.

Abstract: An accurate diagnosis is important for the medical treatment of patients suffered from brain disease. Nuclear magnetic resonance images are commonly used by technicians to assist the pre-clinical diagnosis, rating them by visual evaluations. The classification of NMR images of normal and pathological brains poses a challenge from technological point of view, since NMR imaging generates a large information set that reflects the conditions of the brain. In this work, we present a computer assisted diagnosis method based on a wavelet-entropy (In this paper 2D-discrete wavelet transform has been used, in that it can extract more information) of the feature space approach and a Naive Bayes classifier classification method for improving the brain diagnosis accuracy by means of NMR images. The most relevant image feature is selected as the wavelet entropy, which is used to train a Naive Bayes classifier. The results over 64 images show that the sensitivity of the classifier is as high as 94.50%, the specificity 91.70%, the overall accuracy 92.60%. It is easily observed from the data that the proposed classifier can detect abnormal brains from normal controls within excellent performance, which is competitive with latest existing methods. © Springer International Publishing Switzerland 2015.

Abstract: By employing Lyapunov functional method and linear matrix inequalities (LMIs), the asymptotical stability is studied for the coupled delayed neural networks. Furthermore, we presented a new neural network model including both intrinsic disturbance of single node and communication noise over the network connections. Only one controller is used for the stabilization of the neural networks in terms of LMIs, and the prescribed L2-gain condition is satisfied. The proposed linear matrix inequality results are easy to be solved by standard commercial software. An illustrative example is given to show the effectiveness of the result. © 2014 Elsevier B.V.

Abstract: The formation of pores in sealing the vacuum plate edges by glazing. The impact of the glazing conditions, including but not limited to the glazing temperature, molar ratio and average size of the sealing solder, on the microst ructures, phase structures, contents and porosity at the sealed edges was investig ated with scanning electron microscopy, energy dispersive spectroscopy and electr on backscattered diffraction. The results show that the glazing temperature and a verage powder size of solder strongly affect the porosity. To be specific, as the glazing temperature increased and the average solder grain-size decrease, both the number and size of pores decreased, and the sealed edges became increasingly smooth, uniform and compact. The gases adsorbed by powder surfaces and/or trapped in the spaces enclosed by grain boundaries account for the formation of pores in glazing. We suggest that the optimized size of solder powder and glazing temperat ure may significantly reduce or eliminate the pores formed in glazing the vacuum-plate edges. ©, 2015, Zhenkong Kexue yu Jishu Xuebao/Journal of Vacuum Science and Technology.

Abstract: The cubic phase function (CPF) is an effective method to estimate instantaneous frequency rate (IFR) of frequency modulated signals, but it suffers from performance degradation in the presence of noise, higher-order phase (HP) and multi-component. In this paper, an IFR estimator based on summarizing the auto-terms of cubic phase function (CPF) is proposed to solve these problems. Simulation results indicate the proposed technique can not only provide a lower estimation signal-to-ratio threshold for single-component signal, but also a better rejection of cross-terms of multi-component than CPF, thus gives a higher performance of IFR estimation. © 2015 IEEE.

Abstract: In this study, three types of coupling agent, titanium tris(dodecylbenzenesulfonate) isopropoxide (NDZ 109), γ-methacryloxypropyltrimethoxysilane (KH570) and vinyltrim + ethoxysiloxane homopolymer (SG-Si6490), were utilized to reduce the polar surface energy of barium titanate (BaTiO<inf>3</inf>) particles from 37.53 mJ m<sup>-2</sup> to 0.77 mJ m<sup>-2</sup>, 16.52 mJ m<sup>-2</sup> and 5.46 mJ m<sup>-2</sup>, respectively. At 30 vol% filler loading, NDZ 109 treated BaTiO<inf>3</inf> with the lowest polar surface tension exhibited a remarkable compatibility with ethylene propylene diene monomer (EPDM) gum shown by the bound rubber content. It is found that just 1% (by weight of BaTiO<inf>3</inf> amount) coupling agents SG-Si6490 can raise the tensile strength of EPDM with untreated BaTiO<inf>3</inf> composite from 1.94 MPa to 9.00 MPa, due to the C=C bonds from vinyl groups. In terms of electrical properties, when untreated BaTiO<inf>3</inf> loading was 30 vol%, the dielectric constant of EPDM control can increase from about 2 to 7. Moreover, the SG-Si6490 treated BaTiO<inf>3</inf> further improved the dielectric constant of EPDM with untreated BaTiO<inf>3</inf> composite from 7 to around 8. EPDM with NDZ109 treated BaTiO<inf>3</inf> composite exhibited the lowest volume resistivity among EPDM composites. This journal is © 2015 The Royal Society of Chemistry.

Abstract: Based on SO(3) rotation group theory, a method is presented to fit αβ-crystalline structure on to its corresponding electron microscopy (EM) model for the further diagnosis of crystalline disease. Taken EM model as a kind of αβ-crystalline model rotation deformation, image processing techniques are firstly preformed and then mesh generation adopted on the obtained EM, depending upon its molecular features. Secondly, rigid-body fitting is performed to fit αβ-crystalline Protein Data Bank (PDB) data onto its EM by using SO(3) rotation group theory. Among the fitting process, FFT is adopted to tackle the problems of large data and high computation. The PDB file is obtained from NCBI and EM file obtained from EMBL-EBI. All of the tools are developed by CVC, ICES, the University of Texas at Austin. The experimental results show that it’s a precise and efficient method of fitting αβ-crystalline PDB crystal structure onto its EM model. © 2015, Springer Science+Business Media New York.

Abstract: The identifying of influential nodes in large-scale complex networks is an important issue in optimizing network structure and enhancing robustness of a system. To measure the role of nodes, classic methods can help identify influential nodes, but they have some limitations to social networks. Local metric is simple but it can only take into account the neighbor size, and the topological connections among the neighbors are neglected, so it can not reflect the interaction between the nodes. The global metrics is difficult to use in large social networks because of the high computational complexity. Meanwhile, in the classic methods, the unique community characteristics of the social networks are not considered. To make a trade off between affections and efficiency, a local structural centrality measure is proposed which is based on nodes' and their 'neighbors' structural holes. Both the node degree and "bridge" property are reflected in computing node constraint index. SIR (Susceptible-Infected-Recovered) model is used to evaluate the ability to spread nodes. Simulations of four real networks show that our method can rank the capability of spreading nodes more accurately than other metrics. This algorithm has strong robustness when the network is subjected to sybil attacks. © 2015 Chinese Physical Society.
