The Performance Of Multiple Noise Barriers

Journal of Sound and Vibration, 1994
Abstract A numerical model, based on boundary element techniques, was used to solve the acoustic wave equation in two dimensions, in order to study the performance of various configurations of road traffic noise barriers. The mean insertion loss for a broadband road traffic noise source over a range of receiver positions behind the barrier is used as

Constrained consensus with multiplicative noises

2016 12th IEEE International Conference on Control and Automation (ICCA), 2016
In this paper, we consider the constrained consensus problem of discrete multi-agent systems subject to multiplicative noises. Each agent can only receive information corrupted by noises from its neighbors. The intensities of these noises are dependent on the distance between neighbors' states.

Chinese Remaindering with Multiplicative Noise

Theory of Computing Systems, 2005
We use lattice reduction to obtain a polynomial-time algorithm for recovering an integer (up to a multiple) given multiples of its residues modulo sufficiently many primes, when the multipliers are unknown but small.

ICA in signals with multiplicative noise

IEEE Transactions on Signal Processing, 2005
Independent component analysis (ICA) has been shown in the last few years to be a very useful tool in blind separation of sources and feature extraction. However, at least in its simpler form, its utility is reduced to the case that the outputs are linear mixtures of independent sources. This excludes signals with multiplicative noise.

Multiplicative Noise Protocols

2010
Statistical agencies have conflicting obligations to protect confidential information provided by respondents to surveys or censuses and to make data available for research and planning activities. When the microdata themselves are to be released, in order to achieve these conflicting objectives, statistical agencies apply Statistical Disclosure ...

A Nonconvex Model to Remove Multiplicative Noise

2007
This paper deals with the denoising of SAR images. We draw our inspiration from the modeling of multiplicative speckle noise. By using a MAP estimator, we propose a functional whose minimizer corresponds to the denoised image we want to recover. Although the functional is not convex, we prove the existence of a minimizer.

Multiple frequency estimation in additive and multiplicative colored noises

1999 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings. ICASSP99 (Cat. No.99CH36258), 1999
This paper addresses the problem of estimating sinusoidal frequencies in additive and multiplicative colored noises. Specific Yule-Walker equations yield second-order statistic-based estimates. The frequency estimates are shown to be asymptotically normally distributed. Their asymptotic covariance is derived.

Statistical properties of a laser with multiplicative noise

Optics Letters, 1988
Effects of multiplicative noise on the laser instability in a He-Ne laser are investigated by photon-counting measurements. Several new features, such as the shift of the threshold of laser oscillation and intensity fluctuations in excess of unity, are observed. Our measurements also reveal the importance of the nonlinearity of light-matter interaction
