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 algorith...

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：
The modified Schultz index of a graph is defined as S*(G) = Σ{u, v}⊂V(G)(d(u)·d(v))dG(u, v) where d(u) (or d(v)) is the degree of the vertex u (or v), and dG(u, v) is the distance between u and v. Explicit formulas for calculating the modified Schultz index of Zig-zag polyhex nanotubes are provided in this paper.
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：
The use of ＂ N 不 N＂ has two forms. One is the synunetric structure, and the other is the asymmetric structure. The asymmetric structure of ＂N 不 N＂ has its unique distribution environment in which it often turns into fixed forms by combining with some words and expressions. The forms have varied grammatical functions which can serve as a clause of the complex sentence, and as the subject, the predicate, the object, the attribute, etc. for a minor sentence.

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.
