We study the interaction between two independent nonlinear oscillators competing through a neutral excitable element. The first oscillator, completely deterministic, acts as a normal pacemaker sending pulses to the neutral element which fires when it is excited by these pulses. The second oscillator, endowed with some randomness, though unable to make the excitable element to beat, leads to the...

PURPOSE A three-dimensional finite element analysis based canine heart model is introduced that would enable the assessment of cardiac function. METHODS The three-dimensional canine heart model is based on the cardiac deformation and motion model obtained from the Cardiac Mechanics Research Group at UCSD. The canine heart model is incorporated into ultrasound simulation programs previously de...

The research presented in this thesis is on the application of the injection-locked oscillator technique to microwave balanced oscillators. The balanced oscillator design is primarily analysed using the extended resonance technique. A transmission line is connected between the two active devices, so that the active device resonate each other. The electrical length of the transmission line is al...

A model of auditory scene analysis is proposed, which incorporates an attentional mechanism and is implemented using a network of neural oscillators. The core of the model is a two-layer neural oscillator network which performs stream segregation and selection on the basis of oscillatory correlation. A stream is represented by a sychronised oscillator population, whereas different streams are r...

Introduction: In order to recognize the image of a natural scene, coherent patterns should be extracted and processed separately for reducing the complexity of the problem, because several objects usually exist in a natural scene. D. L. Wang et al. proposed a nonlinear oscillator network model called locally excitatory, globally inhibitory oscillator networks (LEGION) for image segmentation [1]...
