[Blip] and Other Noises
<p><em>[Blip] and Other Noises </em>is a collection of short stories that explores the illusory nature of identity, time, space, and our experience of reality. Its principal characters include a sea captain, an Elvis fanatic, a space alien, and some very confused children. Its principal settings …

Interaction of additive and quantization noises in digital PLLs
Phase-locked loops (PLLs) are a crucial component in modern communications systems. Comprising of a phase-detector, linear filter, and controllable oscillator, they are widely used in radio receivers to retrieve the information content from remote signals. As such, they are capable of signal …

Constructing an Informative Prior Distribution of Noises in Seasonal Adjustment
Time series data is very common in our daily life. Since they are related to time, most of them show a periodicity. The existence of this periodic in uence leads to our research problem, seasonal adjustment. Seasonal adjustment is generally applied around us, especially in areas of economy and …

Age-Related Changes in Listening Effort for Various Types of Masker Noises
<p>It is well established that older listeners have more difficulty understanding speech in background noise than younger listeners (e.g. Dubno et. al., 1984). Some have attributed this increased difficulty to peripheral hearing loss, while others suggest that older listeners may perceive listening …

A True Random Number Generator Algorithm Using Digital Camera Image Noises Under Varying Lighting Conditions
We present a True Random Number Generator (TRNG) using the images taken by web or mobile phone cameras.

Modelling daily returns of New York Stock Exchange by time series with noises having stable distributions
This thesis provides some modelling procedures for the New York Stock Exchange (NYSE) daily data, using stable distributions. The use of stable distributions was motivated by the fact that traditional normality assumptions are not appropriate for the daily stock returns. Four selected series, two …

Online parameter selection for source separation using non-negative matrix factorization
… classical DSP techniques to deal with stationary noises. In this document, we aim to present a study on how to use blind source separation algorithms to denoise audio mixtures containing speech and various background noises. We mainly focus on how to imple- ment an online source separation …

Investigation of the effects of various types of realistic noise and music on a computer-generated graphics interpretation VDT task
… minutes) to determine the influence of realistic noises on task performance. Implementation of a mixed two-by-seven complete factorial design was used to investigate the influence of noise on a) objective performance measures (number of questions answered, and errors) and b) subjective perceptions …

GNSS Integrity Monitoring with Modelling Temporal Correlated Measurement Noise and an Application to RTK
… and provide timely alarms. GNSS measurement noises are typically assumed to be uncorrelated Gaussian white noises in KF for GNSS integrity monitoring. However, this assumption does not hold in practical applications because GNSS observations can be contaminated by hardware noise, multipath, …

Instructional requirements for using the HML and NRR methods for estimating protected exposure levels under hearing protectors
… of an individual to subjectively classify noises as high frequency-dominated, or low-frequency-dominated. Of the 12 pink and industrial noises used, only three could be correctly identified more than 90% of the time. This suggests that subjective classifications of noises should not be …

Objective Predictor metric of Annoyance for Hydraulic Engine Mount Cavitation

Hydraulic engine mount cavitation, the noise heard from the collapse of vapor bubbles in the mount, is considered one of those unexpected noises. During the design phase of a vehicle when an unexpected noise is …

The Art of the Commonplace: Found Sounds in Compositional Practice
… of the emergence of found sounds or everyday noises as a compositional strategy in Western art music through the first half of the 20th century. Pioneering works are examined to determine the motives and aesthetic goals that first led composers to bring noise to the musical surface, including …

Soundgen : a Web services based sound generation system for the psychoacoustics laboratory
… Soundgen are combinations of various tones and noises, produced by a dedicated server running Linux, MATLAB, Apache, and PHP. As an example, Soundgen can generate a sound containing two tones of 500ms duration, each with its own frequency and phase, and can produce them over a broadband …
