I/O Analysis and Optimization for an AMR Cosmology Application
Found in: Cluster Computing, IEEE International Conference on
By Jianwei Li, Wei-keng Liao, Alok Choudhary, Valerie Taylor
Issue Date:September 2002
pp. 119
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
Found in: Intelligent Computation Technology and Automation, International Conference on
By Yang Jianwei, Li Min, Li Jie
Issue Date:October 2009
pp. 232-235
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
Found in: 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
pp. 2854-2861
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

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
Found in: Networked Computing and Advanced Information Management, International Conference on
By Deng Yubo, Niu Jianwei, Li Lian
Issue Date:August 2009
pp. 1176-1179
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...
