Research on Integration of Safety Analysis in Model-Driven Software Development
Found in: Information Assurance and Security, International Symposium on
By Chen Feng, Li Weihua, Fang Dingyi, Chen Xiaojiang
Issue Date:August 2009
pp. 303-306
This paper proposes a new method aiming at integrating the safety analysis in software design and development. Model Driven Architecture is used for the basic framework. By making use of UML extension, UMLsec models the Platform Independent Model of softwa...
 
Flow Field Modulation
Found in: IEEE Transactions on Visualization and Computer Graphics
By Bo Ren, Chen-Feng Li,M. C. Lin,T. Kim, Shi-Min Hu
Issue Date:October 2013
pp. 1708-1719
The nonlinear and nonstationary nature of Navier-Stokes equations produces fluid flows that can be noticeably different in appearance with subtle changes. In this paper, we introduce a method that can analyze the intrinsic multiscale features of flow field...
 
View-Dependent Multiscale Fluid Simulation
Found in: IEEE Transactions on Visualization and Computer Graphics
By Yue Gao, Chen-Feng Li, Bo Ren, Shi-Min Hu
Issue Date:February 2013
pp. 178-188
Fluid flows are highly nonlinear and nonstationary, with turbulence occurring and developing at different length and time scales. In real-life observations, the multiscale flow generates different visual impacts depending on the distance to the viewer. We ...
 
Fisheye Video Correction
Found in: IEEE Transactions on Visualization and Computer Graphics
By Jin Wei,Chen-Feng Li,Shi-Min Hu,Ralph R. Martin,Chiew-Lan Tai
Issue Date:October 2012
pp. 1771-1783
Various types of video can be captured with fisheye lenses; their wide field of view is particularly suited to surveillance video. However, fisheye lenses introduce distortion, and this changes as objects in the scene move, making fisheye video difficult t...
 
TI: an efficient indexing mechanism for real-time search on tweets
Found in: Proceedings of the 2011 international conference on Management of data (SIGMOD '11)
By Beng Chin Ooi, Chun Chen, Feng Li, Sai Wu
Issue Date:June 2011
pp. 649-660
Real-time search dictates that new contents be made available for search immediately following their creation. From the database perspective, this requirement may be quite easily met by creating an up-to-date index for the contents and measuring search qua...
