Nonlinear dynamics support a linear population code in a retinal target-tracking circuit.

A basic task faced by the visual system of many organisms is to accurately track the position of moving prey. The retina is the first stage in the processing of such stimuli; the nature of the transformation here, from photons to spike trains, constrains not only the ultimate fidelity of the tracking signal but also the ease with which it can be extracted by other brain regions. Here we demonst...

A New Modified Particle Filter With Application in Target Tracking

The particle filter (PF) is a novel technique that has sufficiently good estimation results for the nonlinear/non-Gaussian systems. However, PF is inconsistent that caused mainly by loss of particle diversity in resampling step and unknown a priori knowledge of the noise statistics. This paper introduces a new modified particle filter called adaptive unscented particle filter (AUPF) to overcome th...

Investigating the Dynamics of a Ball-Spring Autobalancer in a Rotor with Non-Linear Bearings

Although the traditional automatic ball balancer (ABB) has numerous advantages, it has two major deficiencies, i.e., it has a limited balance stable region and it increases the vibration amplitude of the rotor at transient state. These deficiencies limit the applicability of ABBs. In this regard, a new type of ABB called “the Ball-spring autobalancer” has been proposed to resolve the mentioned ...

Complex Dynamics in Hysteretic Nonlinear Oscillator Circuit

The present paper introduces a new, fourth order, analogue chaos generator, aiming at noise, random pulse and spread spectrum signal applications. The proposed system has a simpler implementation compared to other circuits reported in the literature, using only one nonlinear element, namely a Schmitt trigger type hysteretic block, and leading to a uniform circuit structure. The analysis of the ...

Nonlinear Electronics: a Linear Time-Varying Circuit Approach

Given a nonlinear electronic circuit, an associated linear time-varying small-signal circuit is formally derived by the tableau-method. It has the same topology as the original circuit while each original circuit element is replaced by an incremental one, evaluated along the signal-dependent nonlinear circuit solution. Since the variational circuit is linear in the first place, the designer is ...
