A stochastic differential equation model is considered for nonlinear oscillators under excitations of combined Gaussian and Poisson white noise. Since the solutions of stochastic differential equations can be interpreted in terms of several types of stochastic integrals, it is sometimes confusing about which integral is actually appropriate. In order for the energy conservation law to hold unde...

This paper will examine research on noise and health and suggest new topics and methods of investigation. First, it will discuss noise exposure and argue that new approaches need to be considered. Secondly, it will examine possible underlying mechanisms and show that it is inappropriate to use stress as a model for effects of noise on health. The next section will suggest that it is important t...

Most DFT domain based speech enhancement methods are dependent on an estimate of the noise power spectral density (PSD). For non-stationary noise sources it is desirable to estimate the noise PSD also in spectral regions where speech is present. In this paper a new method for noise tracking is presented, based on eigenvalue decompositions of correlation matrices that are constructed from time s...

Noise pollution is one of the four major pollutions in the world. In order to implement adequate strategies for noise control, assessment of traffic-generated noise is essential in city planning and management. The aim of this study was to determine whether space syntax could improve the predictive power of noise simulation. This paper reports a record linkage study which combined a documentary...

We present a novel automatic speech recognition (ASR) scheme which uses the recently proposed noise robust exemplar matching framework for speech enhancement in the front-end. The proposed system employs a GMM-HMM back-end to recognize the enhanced speech signals unlike the prior work focusing on template matching only. Speech enhancement is achieved using multiple dictionaries containing speec...

background: educational centers have higher standards for controlling noise pollution as it has been shown that noise pollution is a major cause of discomfort for teachers and students. noise pollution reduces concentration, interferes in the conversation, and leads to dropouts and lower grades especially in mathematics. the present study aimed to evaluate noise pollution in the schools of birj...

When the transformer is running, vibration which generated in core and winding will spread outward through medium of metal, oil, air. The magnetic field changes with variation excitation source state core, so corresponding noise change. Therefore, contain a lot information. If information can be associated fault characteristics transformer, it significant to evaluate running signal, improve int...

This paper reports comparative analyses of phase noise in Hartley, Colpitts, and common-source cross-coupled differential pair LC oscillator topologies in 28 nm CMOS technology. The impulse sensitivity function is used to carry out both qualitative and quantitative analyses of the phase noise exhibited by each circuit component in each circuit topology with oscillation frequency ranging from 1 ...
