A new coding method for speech and audio signals
(IEEE, 2005)
In this paper a new representation or modeling method of speech signals is introduced. The proposed method is based on the generation of the so-called Predefined Signature S={S R } and Envelope vector E={E K } Sets (PSEVS). ...
Robust stability analysis of a class of delayed neural networks
(2012)
This paper studies the global robust stability of delayed neural networks. A new sufficient condition that ensures the existence, uniqueness and global robust asymptotic stability of the equilibrium point is presented. The ...
Occlusion aware motion compensation for video frame rate up-conversion
(2010)
Since the emergence of high definition (HD) display technologies, video standards conversion problem has become an important issue in storage, transmission and display of video content. Video frame rate up-conversion (FRUC) ...
Power control in the cognitive cooperative multiple access channel
(IEEE, 2012)
We extend several encoding and decoding techniques from cooperative communications framework, to a cognitive radio system consisting of a primary user (PU) and a secondary user (SU), sending their messages to a common ...
An annular CMUT array beamforming system for high-frequency side looking IVUS imaging
(2010)
A CMUT annular array system for Side-Looking Intravascular Ultrasound (SL-IVUS) with fixed transmit and dynamic receive focusing capabilities has been developed. The system was experimentally characterized and validated ...
Simulated annealing based optimization of dual-ring arrays for forward-looking IVUS and ICE imaging
(2010)
Forward-Looking (FL) catheter based imaging systems are highly desirable for guiding interventions in intravascular ultrasound (IVUS) and intracardiac echocardiography (ICE) applications. One of the main challenges in the ...
A novel image compression method based on classified energy and pattern blocks: initial results
(Springer, 2010)
In this work, a new method for the compression of the images based on the generation of the so called classified energy and pattern blocks is introduced and the initial results are presented. The initials results proved ...
A novel hybrid electrocardiogram signal compression algorithm with low bit-rate
(Springer, 2010)
In this paper, a novel hybrid Electrocardiogram (ECG) signal compression algorithm based on the generation process of the Variable-Length Classified Signature and Envelope Vector Sets (VL-CSEVS) is proposed. Assessment ...
Solid-state SL-IVUS arrays based on non-uniform aperture sampling
(IEEE, 2010)
We propose new reconfigurable ring and cylindrical array designs using non-uniform (Fresnel) aperture sampling with identical differential delays between adjacent elements which reduces the beamformer complexity. For ...
Phased subarray imaging for low-cost, wideband coherent array imaging
(IEEE, 2003)
The front-end hardware complexity of conventional full phased array (FPA) imaging is proportional to the number of array elements. Phased subarray (PSA) imaging has been proposed as a method of reducing the hardware ...
