Monocular organization of the goldfish horizontal neural integrator was studied during spontaneous scanning saccadic and fixation behaviors. Analysis of neuronal firing rates revealed a population of ipsilateral (37%), conjugate (59%), and contralateral (4%) eye position neurons. When monocular optokinetic stimuli were employed to maximize disjunctive horizontal eye movements, the sampled popul...

this paper introduces a technique for controlling a class of uncertain chaotic systems using an adaptive fuzzy proportional-integrator-derivative (pid) controller with h∞ tracking performance. the purpose of this work is to achieve optimal tracking performance of the controller using backtracking search algorithm (bsa). bsa, which is a novel heuristic algorithm, has an easy structure with singl...

In long-time numerical integration of Hamiltonian systems, and especially in molecular dynamics simulation, it is important that the energy is well conserved. For symplectic integrators applied with sufficiently small step size, this is guaranteed by the existence of a modified Hamiltonian that is exactly conserved up to exponentially small terms. This article is concerned with the simplified T...

In this paper there is developed and tested a parallel scheme for the solution of linear systems of ordinary initial value problems based on the box scheme and a modified recursive doubling technique. The box scheme may be replaced by any stable integrator. The algorithm can be modified to solve boundary value problems. Software for both problems is available upon request. 1. Introduction. We c...

Incorporating partial momentum refreshment into Magnetic Hamiltonian Monte Carlo (MHMC) to create with (PMHMC) has been shown improve the sampling performance of MHMC significantly. At same time, from an integrator-dependent shadow or modified target density utilised boost acceptance rates (HMC), which leads more efficient as integrator is better conserved by than true Hamiltonian. Sampling ass...

Portable electronic systems require low-voltage low-power building blocks. An important building block is an A/D converter. ∆Σ ADCs provide an efficient way of trading off speed for resolution. The switched opamp (SO) technique allows design of switched-capacitor (SC) circuits at very low supply voltage without the use of multithreshold technologies or voltage multipliers to drive the switches ...

We examine a new 2nd order integrator recently found by Omelyan et al. The integration error of the new integrator measured in the root mean square of the energy difference, 〈∆H2〉1/2, is about 10 times smaller than that of the standard 2nd order leapfrog (2LF) integrator. As a result, the step size of the new integrator can be made about three times larger. Taking into account a factor 2 increa...

Stability properties for a class of reset systems, such as systems containing a Clegg integrator, are investigated. We present Lyapunov based results for verifying L2 and exponential stability of reset systems. Our results generalize the available results in the literature and can be easily modified to cover Lp stability for arbitrary p ∈ [1,∞]. Several examples illustrate that introducing rese...
