Noise Reduction Technology of Random Vibration Signal Based on Singular Entropy Theory
Information Science and Engieering, International Symposium on
By Zhang Jianwei, Li Huokun
Issue Date:December 2009
Structural random vibration effective information extraction is one of the most important issues to study the dynamic characteristics of engineering structures. Combined with singular entropy theory, an effective method of noise reduction for random vibrat...
Parallel netCDF: A High-Performance Scientific I/O Interface
By Jianwei Li, Wei-keng Liao, Alok Choudhary, Robert Ross, Rajeev Thakur, William Gropp, Rob Latham, Andrew Siegel, Brad Gallagher, Michael Zingale
Issue Date:November 2003
Dataset storage, exchange, and access play a critical role in scientific applications. For such purposes netCDF serves as a portable, efficient file format and programming interface, which is popular in numerous scientific application domains. However, the...
I/O Analysis and Optimization for an AMR Cosmology Application
Cluster Computing, IEEE International Conference on
By Jianwei Li, Wei-keng Liao, Alok Choudhary, Valerie Taylor
Issue Date:September 2002
In this paper, we investigate the data access patterns and file I/O behaviors of a production cosmology application that uses the adaptive mesh refinement (AMR) technique for its domain decomposition. This application was originally developed using Hierarc...
Simulation of Hydraulic Semi-Active Suspension System Based on the Adaptive Fuzzy Control
Intelligent Computation Technology and Automation, International Conference on
By Yang Jianwei, Li Min, Li Jie
Issue Date:October 2009
A four-degree of freedom semi-active hydraulic suspension model and the equation of state for a half of vehicle are built. For time-variation and nonlinearity of the vehicles suspension system, it is appropriate to use the fuzzy control method that does no...
Sparse Dictionary Learning for Edit Propagation of High-Resolution Images
2014 IEEE Conference on Computer Vision and Pattern Recognition (CVPR)
By Xiaowu Chen,Dongqing Zou,Jianwei Li,Xiaochun Cao,Qinping Zhao,Hao Zhang
Issue Date:June 2014
We introduce a method of sparse dictionary learning for edit propagation of high-resolution images or video. Previous approaches for edit propagation typically employ a global optimization over the whole set of image pixels, incurring a prohibitively high ...
Data-Driven Season Characteristic Enhancement of Natural Image
2013 Seventh International Conference on Image and Graphics (ICIG)
By Feng Ding,Jianwei Li,Dongqing Zou,Xiaowu Chen
Issue Date:July 2013
We present a system of creating new scenes in different seasons from an input image captured in a particular season by stylizing it according to similar images in our library which includes a vast number of different season scenes and objects. Firstly, we ...
Fuzzy-PID Control System Simulation of the Semi-active Vehicle Suspension
Digital Manufacturing and Automation, International Conference on
By Yang Jianwei, Li Jie, Jia Zhixuan, Zhang Huigang
Issue Date:December 2010
A half-vehicle 4-DOF dynamic model was built up, as a non-linear, time-delay and uncertain system of vehicle suspension, the parameters of self-adjusting fuzzy PID controller was designed of semi-active suspension, which to achieve the functions of PID par...
Modeling of Broadcasting Based on Distance Scheme for WSN
Networked Computing and Advanced Information Management, International Conference on
By Deng Yubo, Niu Jianwei, Li Lian
Issue Date:August 2009
The modeling of the natural WSN (Wireless Sensor networks) is very difficult because of its complexity. Therefore, the normal way is to evaluate various broadcasting protocols for WSN in simulation. The actual structure of WSN really can be modeled via sim...

Issue Date:August 2008
With the rapid development of computing technologies and network technologies, Grid technology has emerged as the solution for high-performance computing. Recently, the grid of orient-services has become a hot issue in this research area. In this paper, we...
A Motor Fault Diagnosis Method Based on Immune Mechanism
Intelligent Information Technology Applications, 2007 Workshop on
By Fu Duan, Ming Lei, Jianwei Li, Yuling Tian
Issue Date:December 2007
In this paper, a framework of fault diagnosis system is proposed, which is based on negative selection algorithm and the immune network model. Firstly, train the detectors by immune tolerance, and then detect if faults appear. Diagnosis experiments show th...
Fingerprint Minutiae Matching Based on Coordinate System Bank and Global Optimum Alignment
Pattern Recognition, International Conference on
By Wei Wang, Jianwei Li, Weimin Chen
Issue Date:August 2006
Minutiae pattern remains a widely used representation of a fingerprint. The research on minutiae matching never stops due to its complexity and intractability. In this paper, an efficient fingerprint minutiae matching algorithm is proposed. To obtain relia...
A GIS-Based Forest Visual Simulation System
Image and Graphics, International Conference on
By Qizhi Yu, Chongcheng Chen, Zhigeng Pan, Jianwei Li
Issue Date:December 2004
This paper reports on a visual simulation system that supports GIS-based realistic modeling and real-time rendering of forest scenes. Geometric models of trees are automatically generated according to inventory database and pre-designed template models. A ...
A Novel Strategy Enhancing Location Cloaker for Privacy in Location Based Services
Computer Science and Software Engineering, International Conference on
By Chenliang Wang, Jianwei Li, Juanjuan Chen, Zhi Zhuang, Yaxin Zhou
Issue Date:December 2008
Prosperity of mobile devices makes location-based services more and more popular in recent years. However, with existing service infrastructure, users have to reveal their location information in order to access location based services. It is possible that...
