| 摘要: Based on SO(3) rotation group theory, a method is presented to fit -crystalline structure on to its corresponding electron microscopy (EM) model for the further diagnosis of crystalline disease. Taken EM model as a kind of -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 -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 -crystalline PDB crystal structure onto its EM model. | ||||||

| 摘要: 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. | ||||||||||||||

| 摘要: 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 L-2-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. (C) 2014 Elsevier B.V.

| 摘要: In this paper, we propose a local and contextual controlled (LCC) fourth order partial differential equation (PDE) method for noise removal. First, a region based fourth order PDE is proposed, which conductance coefficients are chosen adaptively in terms of the domain type. Thus, the proposed method can preserve the advantages of forth order PDE and avoid leaving isolated black and white speckles. Furthermore, the region based fourth order PDE and two discontinuity measures are incorporated into a LCC fourth order PDE, where the joint use of the two discontinuity measures leads to a complementary effect for edge preservation. The proposed LCC fourth order PDE is tested on two typical images, including texture image and natural scene image, which show the superiority of the proposed method. | ||||||||||

| 摘要: 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. | ||||||||

| 摘要: In this study, three types of coupling agent, titanium tris(dodecylbenzenesulfonate) isopropoxide (NDZ 109), gamma-methacryloxypropyltrimethoxysilane (KH570) and vinyltrim + ethoxysiloxane homopolymer (SG-Si6490), were utilized to reduce the polar surface energy of barium titanate (BaTiO3) particles from 37.53 mJ m(-2) to 0.77 mJ m(-2), 16.52 mJ m(-2) and 5.46 mJ m(-2), respectively. At 30 vol% filler loading, NDZ 109 treated BaTiO3 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 BaTiO3 amount) coupling agents SG-Si6490 can raise the tensile strength of EPDM with untreated BaTiO3 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 BaTiO3 loading was 30 vol%, the dielectric constant of EPDM control can increase from about 2 to 7. Moreover, the SG-Si6490 treated BaTiO3 further improved the dielectric constant of EPDM with untreated BaTiO3 composite from 7 to around 8. EPDM with NDZ109 treated BaTiO3 composite exhibited the lowest volume resistivity among EPDM composites. |

| 摘要: This paper presents an approach, called LBS, for modelling and implementing the architecture of wireless sensor networks (WSNs) publish/subscribe (Pub/Sub) applications using a local broker subcomponent (LBS) model. Considering the reconfigurability of WSNs applications which is necessary for WSNs middleware, a graph-oriented local broker subcomponent (GOLBS) model is defined based on the LBS model by integrated WSNs middleware with Pub/Sub. Focusing on the evolution specification of reconfiguration and non-predefined dynamic reconfiguration, we define the notations of what is the GOLBS' graph grammars and GOLBS' graph, and show a derivative procedure. We design and implement a prototype system on GOLBS, called Pub/Sub-GOLBS. Performance evaluations imply that GOLBS can easily be constructed, while ensuring good reconfigurability. | ||||||||||

| 摘要: 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.
