Scattered light noise affects the sensitivity of gravitational waves detectors. The characterization such is needed to mitigate it. time-varying filter empirical mode decomposition algorithm suitable for identifying signals with time-dependent frequency as scattered (or scattering). We present a fully automated pipeline based on pytvfemd library, python implementation tvf-EMD algorithm, identif...

introduction: among the environmental pollutions, noise is very important for its physiological  and psychological effects on human. traffic noise is one of the most important pollutants and the  hospitals  are  one  of  the  critical  places  regarding  this  type  of  noise.  for  these  reasons,  in  the  summer  of  1382,  the  traffic  noise  of  mashhad  main  streets  around  the  hospit...

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...

background: ototoxic chemicals can impair the sense of hearing and balance. in the past decades, the ototoxicity of solvents and their interaction with noise have become evident. this study has been carried out in the shoe manufacturing factory in tehran (iran) with the aim of evaluating the combined effects of noise and toluene on the workers' hearing. materials and methods: this cross-se...

Light emitting diodes (LEDs) are excellent candidates for the applications requiring low noise light sources with wavelengths ranging from 200 nm to 900 nm. These applications include the detection of fluorescence from protein molecules excited with the ultraviolet (UV) light (200-300nm) for identifying miniscule amounts of hazardous biological pathogens. The detection system including the ligh...

Animal and human data suggest the existence of a cross-species system of analog number representation (e.g., Cordes, Gelman, Gallistel, & Whalen, 2001; Meeck & Church, 1983), which may mediate the computation of statistical regularities in the environment (Gallistel, Gelman, & Cordes, 2006). However, evidence of arithmetic manipulation of these nonverbal magnitude representations is sparse and ...
