Time-scale analysis of abrupt changes corrupted by multiplicative noise [PDF]
Multiplicative Abrupt Changes (ACs) have been considered in many applications. These applications include image processing (speckle) and random communication models (fading).

Introduction: Noise exposure is a common phenomenon in all personal life activities. Due to the prevalence of exposure to noise, many people are exposed to noise. Some of the harmful effects of noise on human health have been proven so far. The purpose

DTI denoising for data with low signal to noise ratios [PDF]
Low signal to noise ratio (SNR) experiments in diffusion tensor imaging (DTI) give key information about tracking and anisotropy, e. g., by measurements with small voxel sizes or with high b values.

Using The Probabilistic Fractal Dimension to Decide if a Time Series is Chaotic [PDF]
In this paper, we use several ways to distinguish between the deterministic time series and stochastic white noise by using correlation exponent test and the BDS test ( Brock Deckert Scheinkman ) ,through simulating a large number of data for testing the

Synaptic shot noise and conductance fluctuations affect the membrane voltage with equal significance [PDF]
The subthresholdmembranevoltage of a neuron in active cortical tissue is a fluctuating quantity with a distribution that reflects the firing statistics of the presynaptic population.

Reduction of magnetic noise limits of orthogonal fluxgate sensor
We have further lowered the white noise of an orthogonal fluxgate to about 0.3 pT/√Hz @ 8 Hz. So far, this is the lowest noise reported for a fluxgate magnetometer.

Spatial Smoothing for Diffusion Tensor Imaging with low Signal to Noise Ratios [PDF]
Though low signal to noise ratio (SNR) experiments in DTI give key information about tracking and anisotropy, e.g. by measurements with very small voxel sizes, due to the complicated impact of thermal noise such experiments are up to now seldom analysed.

Differential effects of white noise in cognitive and perceptual tasks
Beneficial effects of noise on higher cognition have recently attracted attention. Hypothesizing an involvement of the mesolimbic dopamine system and its functional interactions with cortical areas, the current study aimed to demonstrate a facilitation ...

How to Use White Noise Analysis to Make Feynman Integrals Mathematically Rigorous
In this chapter we summarize applications of White Noise Analysis within the framework of Feynman Path Integrals. With more than 30 years of intensive study this field can be seen as one of the most important applications.

Compact conversion and cyclostationary noise modelling of pn junction diodes in low-injection - Part II: Discussion [PDF]
Starting from the compact conversion and cyclostationary pn diode noise model presented in the companion paper, we present an extensive validation based on comparisons with physics-based numerical simulations.
