Survivable Topology Design of Hybrid Fiber-VDSL Access Networks with a Novel Metaheuristic
Found in: Advanced International Conference on Telecommunications
By Rong Zhao
Issue Date:May 2009
pp. 416-422
This paper addresses the topology design of hierarchical Hybrid Fiber-VDSL Access Networks (HFVANs). An efficient strategy is applied to find cost-effective and survivable optical distribution networks with metaheuristics in a short time. A novel metaheuri...
 
Improved Optical Network Topology Redesign Ensuring Biconnectivity
Found in: Advanced International Conference on Telecommunications
By Christian Minge, Rong Zhao, Mathias Schweigel
Issue Date:June 2008
pp. 398-403
This paper presents an efficient strategy for the optical network redesign with a biconnectivity-oriented topology (both two-connected edge and vertex). Based on the graph theory and previous approaches, it is developed to retain essential network links, i...
 
Topology Design of Hierarchical Hybrid Fiber-VDSL Access Networks with ACO
Found in: Advanced International Conference on Telecommunications
By Rong Zhao, Hanjie Liu, Ralf Lehnert
Issue Date:June 2008
pp. 232-237
As one of the most efficient access solutions, VDSL technology is becoming a highlight in the next generation network. This paper addresses the topology design of hierarchical hybrid fiber-VDSL access networks as NP-hard problem. A complete strategy is pro...
 
Continuous-Time Current-Mode Current Mirror Band Pass Filters with Improved Leap-Frog Structure
Found in: Image and Signal Processing, Congress on
By Chunyue Wang, Rong Zhao
Issue Date:May 2008
pp. 146-148
In this paper, the characteristics of the basic current mirror and the continuous-time current-mode current mirror integrator are analyzed. Using the two unlossy loop integrators and the basic current mirrors, the biquad circuit block is implemented. The s...
 
A Novel Video Shot Detection Technique Using Color Anglogram and Latent Semantic Indexing
Found in: Distributed Computing Systems Workshops, International Conference on
By Rong Zhao, William I. Grosky
Issue Date:May 2003
pp. 550
In this paper, we present the results of our work that seeks to negotiate the gap between low-level features and highlevel concepts in the domain of video shot detection. We introduce a novel technique for spatial color indexing, color anglogram, which is ...
 
Optimized Fast Scalar Multiplication Algorithm Based on DBNS
Found in: Information Science and Engineering, International Conference on
By Xin-chun Yin, Rong Zhao
Issue Date:December 2009
pp. 1781-1784
Scalar multiplication is important in elliptic curve cryptography, the time that consumes is significant for it's applications. In this paper, the point arithmetic improved on elliptic curve over binary field such as 3P, 3kP, then proposed an optimized DBN...
 
The Five Ws for Information Visualization with Application to Healthcare Informatics
Found in: IEEE Transactions on Visualization and Computer Graphics
By Zhiyuan Zhang, Bing Wang,F. Ahmed,I. V. Ramakrishnan, Rong Zhao,A. Viccellio,K. Mueller
Issue Date:November 2013
pp. 1895-1910
The Five Ws is a popular concept for information gathering in journalistic reporting. It captures all aspects of a story or incidence: who, when, what, where, and why. We propose a framework composed of a suite of cooperating visual information displays to...
