Aggregated Spectrum Assignment Algorithm Based on Chaotic System in Cognitive Radio
Found in: Computing, Measurement, Control and Sensor Network, International Conference on
By Fei Yang,Min Wang,Shenghui Wang
Issue Date:July 2012
pp. 343-347
To solve the discontinuity of available spectrum in the cognitive radio network, a graph coloring based on aggregation spectrum assignment method is proposed. By aggregate discontinuous spectrum holes in the cognitive network, the proposed method assigns t...
Exploring Ideation: Knowledge Development in Science through the Lens of Semantic and Social Networks
Found in: 2013 46th Hawaii International Conference on System Sciences (HICSS)
By Christine Moser,Julie M. Birkholz,Dirk Deichmann,Iina Hellsten,Shenghui Wang
Issue Date:January 2013
pp. 235-243
In this paper, we explore changes in both structural and semantic characteristics of a scientific social network. We trace the emergence of knowledge, what we refer to as ideation, through publication data from two conferences in a sub-field of Computer Sc...
Research in Character Recognition Based on Generalized Regression Neural Network
Found in: Computing, Measurement, Control and Sensor Network, International Conference on
By Shenghui Wang,Fei Yang
Issue Date:July 2012
pp. 318-320
Template matching and machine learning are the common methods in character recognition. Generalized regression neural network(GRNN) belongs to machine learning, which has the advantages of simple design, fast convergence speed, requiring less training samp...
Research of Intrusion Detection Based on an Improved K-means Algorithm
Found in: Innovations in Bio-inspired Computing and Applications, International Conference on
By Shenghui Wang
Issue Date:December 2011
pp. 274-276
Traditional machine learning methods for intrusion detection can only detect known attacks since these methods classify data based on what they have learned. New attacks are unknown and are difficult to detect because they have not learned. In this paper, ...
Non-contact Discharge Detection System for High Voltage Equipment Based on Solar-Blind Ultraviolet Photomultiplier
Found in: Measuring Technology and Mechatronics Automation, International Conference on
By Shenghui Wang, Fangcheng Lu, Heming Li
Issue Date:March 2010
pp. 773-776
Optical radiation is a very important character signal of high-voltage equipments surface discharge, and it can be used to characterize the equipment insulation condition, but usually, the equipment surface discharge is very weak, and the light signal main...
Evaluating Thesaurus Alignments for Semantic Interoperability in the Library Domain
Found in: IEEE Intelligent Systems
By Antoine Isaac, Shenghui Wang, Claus Zinn, Henk Matthezing, Lourens van der Meij, Stefan Schlobach
Issue Date:March 2009
pp. 76-86
Thesaurus alignments play an important role in realizing efficient access to heterogeneous cultural-heritage data. Current technology, however, provides only limited value for such access because it fails to bridge the gap between theoretical study and pra...
