An Online Multiscale Clustering Algorithm for Irregular Data Sets
Future Computer Sciences and Application, International Conference on
By Tao Guan, Yongling Yu, Tao Xue
Issue Date:June 2011
Clustering analysis has been widely applied to image segmentation, however, many of them cluster convex data sets with an offline way. This paper proposes a new online multiscale competitive learning approach for irregular data sets. This approach defines ...
A Heterogeneous Auto-offloading Framework Based on Web Browser for Resource-Constrained Devices
Internet and Web Applications and Services, International Conference on
By Yang Zhang, Xue-tao Guan, Tao Huang, Xu Cheng
Issue Date:May 2009

By Bifeng Yin,Tao Guan,Shengji Liu
Issue Date:January 2012
The present study is based on the certain air cooled direct injection diesel engine to investigate the combustion characteristic, emission and fuel consumption when the certain diesel engine is fuelled with different ratio of biodiesel. The experiment resu...
Numerical Simulation on the Effect of Pilot Injection on Combustion and NOx Emission Characteristics of Light-Vehicle Diesel Engine
Digital Manufacturing and Automation, International Conference on
By Shengji Liu, Hekun Jia, Bifeng Yin, Zhenwei Xu, Tao Guan
Issue Date:December 2010
Based on KIVA-3V code, the numerical simulation on the combustion process and NOx emission of a light-vehicle diesel engine is carried out, using different injection strategies. The results show that compared with the traditional single injection, pilot in...
Extraction of Greatest Impact Factor in Nonlinear Diagnosis Models
International Conference on E-Business and E-Government
By Suli Wang,Tao Guan
Issue Date:May 2010
For diagnosis models with one response variable influenced by multiple factors, the paper proposes a method that finds the greatest impact factor, referred to as main factor. The method is based on statistical analysis and uses the principal component tran...
An Aggressive Feature Selection Method based on Rough Set Theory
Innovative Computing ,Information and Control, International Conference on
By Fangtao Li, Tao Guan, Xian Zhang, Xiaoyan Zhu
Issue Date:September 2007
Feature selection is an important component of text classification to reduce the data dimensionality. In this paper, we s Heuristic algorithm for rough set reduction, and then propose an aggressive feature selection method for text categorization. This met...
An Autonomic Service Discovery Mechanism to Support Pervasive Device Accessing Semantic Grid
Autonomic Computing, International Conference on
By Tao Guan, Ed Zaluska, David De Roure
Issue Date:June 2007
An important challenge of integrating pervasive devices into Grid environment to enhance pervasive device capabilities is that pervasive devices need to locate, find, select and invoke the appropriate Grid services in an autonomic and flexible way. However...
