Strategic Environmental Assessment in the Application of Preventive Protection for Wind Farm Noise—Case Study: Maestrale Ring Wind Farm

Energies, 2021
Determining the spatial position of wind turbines is the initial and most important phase in the development of a wind farm project. In this sensitive phase, all potential problems that may arise in the later stages of project development should be ...

Phase Noise Modeling of Opto-Mechanical Oscillators [PDF]

, 2010
We build upon and derive a precise far from carrier phase noise model for radiation pressure driven opto-mechanical oscillators and show that calculations based on our model accurately match published phase noise data for such oscillators.

Magnetic Noise Prediction and Evaluation in Tunneling Magnetoresistance Sensors

Sensors, 2018
We propose a simple model for prediction of magnetic noise level in tunneling magnetoresistance (TMR) sensors. The model reproduces experimental magnetic 1/f and white noise components, which are dependent on sensors resistance and field sensitivity. The

Advances in Research on Low-dose CT Imaging Algorithm Based on Deep Learning

CT Lilun yu yingyong yanjiu, 2022
Computed tomography (CT) is widely used in clinical diagnosis because of its fast imaging speed and high resolution. However, higher doses of radiation will cause damages to human tissues and organs, while lower doses will lead to serious deterioration ...

Psychoacoustic modelling of rotor noise [PDF]

The Journal of the Acoustical Society of America, 2022
The aviation sector is rapidly evolving with more electric propulsion systems and a variety of new technologies of vertical take-off and landing manned and unmanned aerial vehicles. Community noise impact is one of the main barriers for the wider adoption of these new vehicles.

A Novel Approach for Modeling and Digital Generation of RF Signals Distorted by Bandlimited Phase Noise

IEEE Journal of Microwaves, 2022
In radar and communication systems, phase noise is one of the main causes of performance degradation. Phase noise increases the uncertainty in radar measurements and limits the achievable data rates in communication systems.

Pilot-aided carrier synchronization using an approximate DCT-based phase noise model [PDF]

, 2007
This contribution deals with phase noise estimation from pilot symbols. The phase noise process is approximated by an expansion of DCT basis functions containing only a few terms.

Hyperspectral Image Restoration Combining Intrinsic Image Characterization With Robust Noise Modeling

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
In hyperspectral image (HSI) processing, a fundamental issue is to restore HSI data from various degradations such as noise corruption and information missing.

The interplay of intrinsic and extrinsic bounded noises in genetic networks [PDF]

, 2012
After being considered as a nuisance to be filtered out, it became recently clear that biochemical noise plays a complex role, often fully functional, for a genetic network.
