Design of VQ-Based Hybrid Digital-Analog Joint Source-Channel Codes for Image Communication
Found in: Data Compression Conference
By Yadong Wang, Fady Alajaji, Tamás Linder
Issue Date:March 2005
pp. 193-202
A joint source-channel coding system for image communication over an additive white Gaussian noie channel is presented. It employs vector quantization based hybrid digital-analog modulation techniques with bandwidth compression and expansion for transmitti...
Improved or Green Wave-Guide Methods in the Acoustic Emission Inspection of High / Low-Temperature or Complicated Vessels
Found in: 2012 Third Global Congress on Intelligent Systems (GCIS)
By Yanting Xu,Xiaowei Wang,Yadong Wang
Issue Date:November 2012
pp. 323-326
Acoustic emission (AE) sensors are used to detect acoustic signals from serious and active defects of vessels inspected. Ordinary AE sensors generally can not be directly coupled on walls of high/low-temperature or complicated vessels because of the limita...
Weighted Network-Based Inference of Human MicroRNA-Disease Associations
Found in: Frontier of Computer Science and Technology, Japan-China Joint Workshop on
By Qinghua Jiang, Yangyang Hao, Guohua Wang, Tianjiao Zhang, Yadong Wang
Issue Date:August 2010
pp. 431-435
The identification of disease microRNAs is vital for understanding the pathogenesis of diseases at the molecular level, and is critical for designing specific molecular tools for diagnosis, treatment and prevention. However, one major issue in microRNA stu...
Modelling non-stationary gene regulatory process with hidden Markov Dynamic Bayesian Network
Found in: 2012 IEEE International Conference on Bioinformatics and Biomedicine (BIBM)
By Shijiazhu ,Yadong Wang
Issue Date:October 2012
pp. 1-4
Dynamic Bayesian Network (DBN) has been widely used to infer gene regulatory network from time series gene expression dataset. The standard assumption underlying DBN is based on stationarity, however, in many cases, the gene regulatory network topology mig...
Privacy-Preserving Data Mining Based on Sample Selection and Singular Value Decomposition
Found in: Internet Computing and Information Services, International Conference on
By Guang Li,Yadong Wang
Issue Date:September 2011
pp. 298-301
For improving the PPDM (privacy-preserving data mining) methods based on matrix decomposition, this paper proposed a new PPDM method both using sample selection and matrix decomposition. The original matrix decomposition-based methods perform attribute ext...
A new real-zero conversion algorithm
Found in: Acoustics, Speech, and Signal Processing, IEEE International Conference on
By R. Kumaresan, Yadong Wang
Issue Date:June 2000
pp. 313-316
The odd-order real zeros of a real-valued signal, s(t), correspond to its conventional or overt zero-crossings. The overt zero-crossings can be easily determined. But the complex zeros of s(t) are not easy to determine. This suggests the possibility of con...
