Equilibrium and stability analysis of delayed neural networks under parameter uncertainties
(Elsevier Science Inc, 2012-02-15)
This paper proposes new results for the existence, uniqueness and global asymptotic stability of the equilibrium point for neural networks with multiple time delays under parameter uncertainties. By using Lyapunov stability ...
3-D Mesh geometry compression with set partitioning in the spectral domain
(IEEE-INST Electrical Electronics Engineers Inc, 2010-02)
This paper explains the development of a highly efficient progressive 3-D mesh geometry coder based on the region adaptive transform in the spectral mesh compression method. A hierarchical set partitioning technique, ...
Cognitive cooperative MAC with one primary and two secondary users: achievable rates and optimal power control
(IEEE-INST Electrical Electronics Engineers Inc, 2014-11)
We consider a three-user fading cognitive cooperative multiple access channel (MAC) with one primary and two secondary transmitters. We propose two encoding/decoding strategies with varying levels of cooperation, based on ...
Multi-view semi-supervised learning for dialog act segmentation of speech
(IEEE-INST Electrical Electronics Engineers Inc, 2010-02)
Sentence segmentation of speech aims at determining sentence boundaries in a stream of words as output by the speech recognizer. Typically, statistical methods are used for sentence segmentation. However, they require ...
Hierarchical quantization indexing for wavelet and wavelet packet image coding
(Elsevier Science BV, 2010-02)
In this paper, we introduce the quantization index hierarchy, which is used for efficient coding of quantized wavelet and wavelet packet coefficients. A hierarchical classification map is defined in each wavelet subband, ...
An analog integrated circuit beamformer for high-frequency medical ultrasound imaging
(IEEE-INST Electrical Electronics Engineers Inc, 2012-10)
We designed and fabricated a dynamic receive beamformer integrated circuit (IC) in 0.35-mu m CMOS technology. This beamformer IC is suitable for integration with an annular array transducer for high-frequency (30-50 MHz) ...
Robust stability analysis of a class of neural networks with discrete time delays
(Pergamon-Elsevier Science Ltd, 2012-05)
This paper studies the existence, uniqueness and global asymptotic stability of the equilibrium point for the class of neural networks with discrete constant time delays under parameter uncertainties. The class of the ...
