摘要：
We consider the problem of the correspondence leaning of two high-dimensional data sets via the manifold leaning techniques. Itpsilas convenient for us to find the shared latent structure of the high-dimensional data sets, if they can be aligned in a uniformed low-dimensional data space. A local affine technique to address this problem is present here. Our method preserves more geometrical knowledge of the high dimensional data sets and can easily project the new test data into the aligned data space by the local transformation obtained during the training step. The effectiveness of our algorithm is validated by applying it to the problem of image sequences alignment.

摘要：
In order to increase the lifetime of entire wireless sensor network, the task scheduling in the network demands to achieve as far as possible the shortest task completion time, the lowest level of energy consumption and the highest level of balanced use of energy under condition of limitation in energy of nodes. Therefore, traditional multiprocessor Directed Acyclic Graph (DAG) scheduling algorithm can not be directly applied to sensor task scheduling. This paper proposes a Multi-objective Optimal DAG Scheduling (MODAGS) algorithm for wireless sensor networks. Its central idea is to exploit heuristic optimization algorithms and strategies respectively to realize multi-objective optimization in the task scheduling of wireless sensor networks. Then, take those results of single-objective optimal task scheduling as the initial particle swarm in the Particle Swarm Optimization (PSO) algorithm. By way of redefinition of operations in the PSO algorithm, the task scheduling in wireless sensor networks is optimized synthetically. Experimental results show that: combining heuristic optimization algorithm with bionic algorithm, the optimization technology has good realtime performance and high efficiency of energy.
摘要：
In the process of cantilever construction of the Longtan River Bridge ,the WZP-035 thermally sensitive electric resistence, as measured points of temperature, was buried into two segments of box-girder,and the temperature field of box-girder concrete was observed for three days. The observation shows that the temperature distribution of concrete box along the height of box-girder is non-linear under solar radiation. The tested temperature and the temperature difference are given a regression analysis using the least square method. Concrete box-girder temperature mode in the sunshine, suited to the western Hubei Province, is proposed.

摘要：
A new 3D automatic reconstruction method of micro solid of revolution is presented in this paper. In the implementation procedure of this method, image sequence of the solid of revolution of 360° is obtained, which rotation speed is controlled by motor precisely, in the rotate photographic mode of back light. Firstly, we need calibrate the height of turntable, the size of pixel and rotation axis of turntable. Then according to the calibration result of rotation axis, the height of turntable, rotation angle and the pixel size, the contour points of each image can be transformed into 3D points in the reference coordinate system to generate the point cloud model. Finally, the surface geometrical model of solid of revolution is obtained by using the relationship of two adjacent contours. Experimental results on real images are presented, which demonstrate the effectiveness of the Approach.

摘要：
In many practical machine learning and data mining applications, unlabeled training examples are readily available but labeled ones are fairly expensive to obtain. Therefore, semi-supervised learning algorithms have attracted much attention. In this paper, semi-supervised regression via local block coordinate algorithm is proposed. This algorithm preserves more geometrical knowledge of the high-dimensional data by local tangent space alignment, we take the method of automatic alignment of local representations to realize preserving the linear projection between every local coordinate and the global coordinate. Experiments show that method can effectively exploit unlabeled data to improve regression estimates.

摘要：
Propagation of a crack in engineering materials including rocks can cause failure. Knowledge of the stress state under which a crack can propagate, and the trajectory it may follow during its growth are thus very important for stability of rock masses/materials and for safe design of structures in rocks and ceramics. In this paper, the surface’ effective shear stress of closed-crack was introduced into calculating the stress intensity factor (SIF). The value of SIF was calculated when cracks were in different length, different angle and different friction coefficient. Introducing τrθ iso-line, the effective shear stress criterion is developed: (1) the crack grows up along the direction in which the sum of twin shear stress reached minimum on τrθ iso-line; (2) the crack begin to grow when the crack tip stress intensity factor KII arrived at critical value KIIC. Accordingly, the proposed criterion successfully predicts critical cracking angle θc of closed-crack. Compared with other criteria in predicting initiation angles θc, it shows that the effective shear stress criterion is accurate and secure in predicting closed-crack’ fracture.

摘要：
The temporarily fault signals existing in high voltage lines and electric equipments are usually non-linear and non-stationary. Low frequency oscillation characteristic extraction from fault signals plays an important role in online fault monitoring and detection system designing. In this paper we propose a procedure to analyze power system fault signal by employing HTT method. The fault signal is firstly decomposed into intrinsic mode function (IMF) by the empirical mode decomposition (EMD) method. Then instantaneous frequency and instantaneous amplitude is obtained by Hilbert transform to compose Hilbert spectrum. Thus the transient caused by fault can be analyzed and further detected accurately through the instantaneous frequency and the time-frequency-amplitude spectra analysis. Experiments show promising results.

摘要：
Image data taken with various capturing devices are usually multidimensional and therefore they are not very suitable for accurate classification normally expecting to operate only on a small set of relevant features. Locally linear embedding is an effective nonlinear dimensionality reduction method for exploring the intrinsic characteristics of high dimensional data. In this paper, novel local linear embedding for face classification is proposed. We modify the LLE algorithm by preserving more geometrical knowledge of the high-dimensional data, then combining with simple classifiers such as the nearest mean classifier. Experimental simulations are shown to yield remarkably good classification results in high dimension face image sequence.

摘要：
This paper presented an automatic panorama generation and free roaming algorithm for the tedious previous approaches on panorama generation and limitations of single-viewpoint roaming. Firstly, it describes the single-viewpoint panorama generation method: detecting the image point features in SIFT operator, getting the robust homography estimation in RANSAC and stitching the panoramic images by multi-band blending. Secondly, we present the free roaming method. In this method the corresponding pixels in new-viewpoint image can be set from the original images matching points and the new-viewpoint image can be blended by corresponding TIN piece rendering at last. Experimental results show that it is practicable and meets the actual requirements.
