Humans explore static visual scenes by alternating rapid eye movements (saccades) with periods of slow and incessant eye drifts [1-3]. These drifts are commonly believed to be the consequence of physiological limits in maintaining steady gaze, resulting in Brownian-like trajectories [4-7], which are almost independent in the two eyes [8-10]. However, because of the technical difficulty of recor...

Phase drift extremely limits the secure key rate and transmission distance, which is non-negligible in local oscillation continuous variable quantum distribution (LLO CV-QKD). In order to eliminate impact caused by phase drift, we analyze noise of system propose a compensation method based on convolutional neural network (CNN). Moreover, performed signal according estimated value before coheren...

Bessel processes with constant negative drift have recently appeared as heavy-traffic limits in queueing theory. We derive a closed-form expression for the spectral representation of the transition density of the Bessel process of order ν > −1 with constant drift μ = 0. When ν > − 1 2 and μ < 0, the first term of the spectral expansion is the steady-state gamma density corresponding to the zero...

In this paper statistical and time series models are used for determining the random drift of a dynamically Tuned Gyroscope (DTG). This drift is compensated with optimal predictive transfer function. Also nonlinear neural-network and fuzzy-neural models are investigated for prediction and compensation of the random drift. Finally the different models are compared together and their advantages a...

semi-active base isolation system has been proposed mainly to mitigate the base drift of isolated structures while in most cases, its application causes the maximum acceleration of superstructure to be increased. in this paper, designing optimal semi-active base isolation system composed of linear base isolation system with low damping and magneto-rheological (mr) damper has been studied for co...

Application of asulam herbicide by helicopter, as a primary treatment of bracken, requires appropriate buffer zones to protect non-target plants, conservation areas and water catchments from spray drift. Drift from large-scale applications of asulam were monitored at two moorland sites where helicopters were fitted with Delavan RD ‘Raindrop’ drift-reducing, hollow-cone nozzles. Drift was measur...

|The rst analyses of semiconductor devices in the 1940s and 50s already considered a splitting of devices into regions of zero space charge and depletion regions. Here it is shown that these simplied models appear as singular limits of the drift-diiusion model for charge transport in semiconductors. The limiting problem for the potential is similar to the so called space charge problem. For pn-...

This paper formulates Shewhart mean (X-bar) and range (R) control charts for diagnosis and interpretation by artificial neural networks. Neural networks are trained to discriminate between samples from probability distributions considered within control limits and those which have shifted in both location and variance. Neural networks are also trained to recognize samples and predict future poi...
