The effect of multiplicative noise on a system described by two modes close to a bifurcation point is investigated. The bifurcation is assumed stationary and noise acts as random coupling between these modes. An analytic formula that predicts the onset of instability is derived, and the domain of existence of on-off intermittency is calculated based on an eigenvalue problem. This approach, conf...

We consider the Cauchy problem for a degenerate fractional conservation laws driven by noise. In particular, making use of an adapted kinetic formulation, result existence and uniqueness solution is established. Moreover, unified framework also established to develop continuous dependence theory. More precisely, we demonstrate $$L^1$$ -continuous estimates on initial data, order Laplacian, diff...

When applying reinforcement learning (RL) algorithms such as Q-learning to real-world applications, we must consider the influence of sensor noise. The simplest way to reduce such noise influence is to additionally use other types of sensors, but this may require more state space – and probably increase redundancy. Conventional value-function approximators used to RL in continuous state-action ...

Although there is still controversy about its origin, the designer requires accurate models to estimate 1/f noise of the MOS transistor in terms of its size, bias point and technology. Conventional models present limitations; they usually do not consistently represent the series-parallel association of transistors and they may not provide adequate results for all the operation regions, particul...

This paper presents a chopper instrumentation amplifier for interfacing precision thermistor bridges. For high CMRR and DC gain, the amplifier employs a three-stage current-feedback topology with nested-Miller compensation. By chopping both the input and intermediate stages of the amplifier, a 1 mHz noise corner was achieved at an input-referred noise power spectral density (PSD) of 15 nV/ Hz. ...

Previous work has found that one way people infer the direction of causal relationships involves identifying an asymmetry in how causes and effects change over time. In the current research we test the generalizability of this reasoning strategy in more complex environments involving ordinal and continuous variables and with noise. Participants were still able to use the strategy with ordinal a...

An energy-constrained signal subspace (ECSS) method is proposed for speech enhancement and recognition under an additive colored noise condition. The key idea is to match the short-time energy of the enhanced speech signal to the unbiased estimate of the short-time energy of the clean speech, which is proven very e ective for improving the estimation of the noise-like, low-energy segments in sp...

In this paper there are presenting solutions for increasing environmental robustness of a Romanian language continuous speech recognizer, previously built [1], [2] as a man-machine dialogue system. Multistyle training strategy is used to train the recognizer with various levels of artificial noise added on the clean speech. Experimental results prove that this scheme strongly increase the syste...

A-weighted equivalent continuous noise levels of nine companies/industries in Jos-Bukuru metropolis were determined by using Impulse Precision Sound Level Meter Type 2209 in conjunction with -Octave Filter set Type 1616 and an audiometric test of five hundred and twenty four workers out of a total of seven hundred and ninety one volunteers interviewed were carried out. The physical measurements...

Noise-induced hearing loss is one of the most common causes of deafness and, at present, there is no treatment for the recovery of the normal hearing threshold after prolonged exposure to loud acoustic stimuli and the generation of acoustic trauma. Prolonged exposure to noise can cause oxidative stress in the cochlea which results in the loss (via apoptotic pathways) of the outer hair cells of ...
