Li-Yong Zhou, Xiao-Lin Zhang
Currently, the Top-k keyword search of uncertain XML returns only the top k probability value of the root node. We need further processing to constructed the sub-tree that it meet some certain conditions. To solve this problem, this paper defines a new Top-k query semantics SRRT-Top-k that based on the...

The Combination of the Hilbert Transform and the Fourier Transform for Mechanical Vibration Signal Analysis

Xiao Wang, Yan Zhu, Bo Yu
In this paper we propose one method for mechanical vibration signal analysis. The given mechanical vibration signal is firstly decomposed into several intrinsic mode functions (IMFs) by the empirical mode decomposition (EMD) method. The Hilbert transform of each IMF, calculated by a recently developed...

An Event-Based Method of Construction of Cyberspace Models

Youjun Wang, Hongqi Zhang, Tianwei Che, Chuanfu Zhang, YunTian Zhao, Chao Yang
Cyberspace has become an important domain the same as the land, sea, air and space. Many cyberspace models were proposed to explain such a high coupled complex domain, but lack of practical method of construction these models make them hard to function. This paper proposes an event based method of construction...

Parallel-Based Error Metric For Large-Scale Terrain Rendering Method

Zihou Ge, Xianyu Zhang
This paper presents a terrain rendering technique for large, textured terrain, which uses Parallel-based error metric. In a preprocess, the domain was first tiled and computed into a nested geometric space error map based on geographic theory, taking the advantage to save displaying memory with terrain...

The Drawback of Image Resizing Based on Seam Carving

Zijuan Zhang
Lots of image resizing algorithms that based on seam carving belong to the discrete resizing methods. Seam-carving algorithms refer to delete or insert pixel lines in order to resize image’s size. Pixel lines horizontally or vertically pass through the whole image, deleting the pixel line to make the...
