Based on the geometrically nonlinear theory and linear hygrathermal strain-temperature and humidity relation for the axial extensional Euler-Bernoulli beams, governing equations for large post-buckling deformation of the elastic beams with a point space-constraint and subjected to temperature and humidity rising were formulated, in which seven basic unknown functions, such as the arc length of the deformed axial line, the line displacement components, the rotational angle of the cross-section, the internal resultant forces and moment, were included. It is assumed that the point-space constraint be around the middle point of the beam and the space value be in the range of hygrothermal post-buckling deformation. Boundary conditions at the two ends of the beam were considered to be immovably simply supported (pinned-pinned) and fixed (fixed-fixed), respectively. By using shooting method to solve the above mentioned strong nonlinear two-point boundary value problem numerically, hygrothermal post-buckling response of the beam under uniform increment both in temperature and humidity were obtained. Especially, changes in the characteristics of the hygrothermal post-buckling deformation and the internal forces of the beam after its middle point deflection reaches the gap value and at the same time the constraint force arises. Curves of equilibrium paths and configurations of the beams depending on the middle point space-constraint force were presented.

Stochastic stability, tracking performance and robust performance are realized in the multi-objective scheme. By using the Lyapunov stability theory and the peak-to-peak measure, we construct the PI tracking controller to guarantee the stochastic stability and the tracking performance of the stochastic systems, optimize the tracking performance, enhance the ability of the disturbance attenuation and improve the robustness of the stochastic systems. Finally, a numerical example is included to show that the proposed method is feasible.

The size and crystallinity of the ZnS nanostructures were easily controlled by the precursor source and the solvents. The photoluminescence (PL) in the range of 400-650 nm has been observed and the broad band is peaked at about 525 nm. The PL intensity reduced greatly with increasing the nanoparticle size of the as-prepared samples and the ratio of zinc and sulfur sources in the preparation process. Spectral examinations and analyses reveal that the 525 nm emission peak indeed originates from the electronic states determined by the zinc vacancies. © 2010 Springer Science+Business Media, LLC.

Using Karhunen-Loe¨ve transform, PCA transforms the original dataset into lower-dimensional feature data. The transform has directivity both on energy accumulation and data selection. The author points out and proves the two direction characteristics. In this paper, authors proposed a method of edge detection based on PCA. Authors used twice PCA operations, called TPCA, first by process the image by PCA and second by process the transpose of the image by PCA. Experimental results are shown by using some typical images.

Box 211, Amsterdam, 1000 AE, Netherlands Abstract:Nonlinear classification has been a non-trivial task in machine learning for the past decades. In recent years, kernel machines have successfully generalized the inner-product based linear classifiers to nonlinear ones by transforming data into some high or infinite dimensional feature space. However, due to their implicit space transformation and unobservable latent feature space, it is hard to have an intuitive understanding of their working mechanism. In this paper, we propose a comprehensible framework for nonlinear classifier design, called Manifold Mapping Machine (M3). M3 can generalize any linear classifier to nonlinear by transforming data into some low-dimensional feature space explicitly. To demonstrate the effectiveness of M3 framework, we further present an algorithmic implementation of M3 named Supervised Spectral Space Classifier (S3C). Compared with the kernel classifiers, S3C can achieve similar or even better data separation by mapping data into the low-dimensional spectral space, allowing both of its mapped data and new feature space to be examined directly. Moreover, with the discriminative information integrated into the spectral space transformation, the classification performance of S3C is more robust than that of the kernel classifiers. Experimental results show that S3C is superior to other state-of-the-art nonlinear classifiers on both synthetic and real-world data sets. © 2011 Elsevier B.V.
