- Semantic Noise And Interpersonal Communications
- Semantic noise is something that we all need to be aware. Semantic noise is the interpretation of words and phrases that distract us from the meaning of the communication. Semantic noise is something that most of us do without knowing we do it. It can break down the communication quickly...

- Noise Makers
- Content is data, which can be viewed as historical facts, combined with noise - the intentional or unintentional addition of falsehoods to the data - and the recipient is often burdened with refining the content to the point it is useful. Obviously, project teams are being barraged with content every...

- The Branded Customer Experience
- In this marketing-centric economy of instant e-mail offers, hyped CRM, and endless competing media images [aka: noise, noise, noise] ... some, very-select brands actually break through the clutter and create genuine interest, excitement, and loyalty in the marketplace. Beyond simply selling a product ... a location ... or a service,...

- Ultra High Frequency Volatility Estimation With Dependent Microstructure Noise
- The paper analyzes the impact of time series dependence in market microstructure noise on the properties of estimators of the integrated volatility of an asset price based on data sampled at frequencies high enough for that noise to be a dominant consideration. It shows that combining two time scales for...

- Enhanced Directional Smoothing Algorithm for Edge-Preserving Smoothing of Synthetic-Aperture Radar Images
- Synthetic aperture radar SAR images are subject to prominent speckle noise, which is generally considered a purely multiplicative noise process. In theory, this multiplicative noise is that the ratio of the standard deviation to the signal value, the "coefficient of variation," is theoretically constant at every point in a SAR...

- Elimination of the CCD Camera Noise in Microscopic Measurements of Machine Elements
- In this paper the fundamental tasks of a computer measuring system incorporating a CCD cameras were defined. A method for the determination and elimination of camera noise using a multiple exposition approach was shown. Some research results on the level of noise and possible impacts of noise elimination were presented.

- The Effect of Background Noise on P300 to Suprathreshold Stimuli
- Both the amplitude and latency of P300 vary with changes in stimulus parameters. Stimuli at intensities or pitch separations near threshold evoke a smaller and later P300. P300 is also affected by extraneous stimulus parameters in tasks where stimulus frequency separation is large and stimuli are well above intensity thresholds....

- Low-Frequency Noise in TFSOI Lateral N-P-N Bipolar Transistors
- Low-frequency noise is characterized as a function of base current density on thin-film-silicon-on-insulator TFSOI lateral bipolar transistors. In the low injection region of operation, the noise power spectral density was proportional to 1 8 for 0 4 A/ m2, which suggest that the noise in these devices is primarily dominated...

- Foam Underlayment for Floor Assemblies
- QuietFoam is a specially designed 3/8" closed cell polyethylene foam designed to reduce footfall and other impact noise on hardwood or tile floors. QuietFoam, composed of a lightweight, closed cell, extruded polyethylene foam, is acoustically engineered to isolate sound vibrations and impact noises. Wall performance will also increase, as flanking...

- An Analysis of Charge Transfer Efficiency Noise on Proton-Damaged CCDs for the Hubble Space Telescope Wide Field Camera 3
- This paper focuses on the statistical nature of CTE degradation due to damage on one of the irradiated devices with exceptional initial CTE characteristics. In radiation damaged CCDs, CTE noise can be the dominant noise component. In contrast to other noise sources, CTE noise has a component of fixed pattern...

- Computation of Broadband Noise Radiated by a Ducted Fan in an Uniform Flow
- Prediction of ducted-fan broadband noise has become a challenge for reducing aircraft turbofan noise because it dominates overall sound levels at subsonic rotation tip speeds. This paper discusses the equations established in a previous work for a uniform flow inside the duct, the free medium being at rest (case of...

- Low Noise Applications
- This paper focuses on the features of Gore's low noise applications. In the design of today's high performance electrical systems, the self-generation of noise within the system can degrade performance. Generally referred to as turboelectric noise, the effect is to degrade signal integrity in otherwise carefully designed systems or instruments....

- Noise Sources Prediction in a Slat Cove by Mean of a Hybrid Zonal RANS/LES Approach
- This paper describes some significant steps towards the numerical simulation of the noise radiated by the high-lift devices of a plane. A hybrid RANS/LES strategy is proposed to reduce the cost of an accurate numerical prediction of the unsteady noise sources in such configurations. This method allows considering some reduced...

- Potential Subjective Effectiveness of Active Interior Noise Control in Propeller Airplanes
- Active noise control technology offers the potential for weight-efficient aircraft interior noise reduction, particularly for propeller aircraft. However, there is little information on how passengers respond to this type of interior noise control. This paper presents results of two experiments that use sound quality engineering practices to determine the subjective...
