Improvement in Random Noise for Pixel-Parallel Single-Slope ADC with Consideration of Flicker Noise Effect [PDF]

open access: yesSensors
We propose and demonstrate a low-random-noise (RN) design for pixel-parallel single-slope ADCs (SS-ADCs), achieving 2.2 e-rms in a 3.24 µm pixel. In this paper, we discuss AC-based RN estimation with respect to the comparator bias current and a bandwidth-

High-Update-Rate (25 kHz) Laser Ranging with Random Noise Modulation for Fast and Precise Absolute Distance Measurement [PDF]

open access: yesSensors
This paper proposes a technique for precise distance measurement under laser random noise using autocorrelation demodulation. We conducted measurements within a 2 m range using a commercial digitizer with a sampling rate of 40 GS/s.

Noise expresses exponential growth under regime switching [PDF]

open access: yes, 2009
Consider a given system under regime switching whose solution grows at most polynomially, and suppose that the system is subject to environmental noise in some regimes. Can the regime switching and the environmental noise work together to make the system

An improved distributed optimized random differential privacy algorithm

open access: yesNantong Daxue xuebao. Ziran kexue ban, 2023
For the distributed optimization privacy protection problem in multi-agent systems, each agent uses the information of its neighbors to minimize the sum of the objective functions of all agents. The goal is to protect the objective function of each agent

Seismic Random Noise Attenuation Based on PCC Classification in Transform Domain

open access: yesIEEE Access, 2020
Random noise attenuation of seismic data is an essential step in the processing of seismic signals. However, as the exploration environment is becoming more and more complicated, the energy of valid signals is weaker and the signal to noise (SNR) is much

Prestack seismic random noise attenuation using the wavelet-inspired invertible network with atrous convolutions spatial pyramid

open access: yesFrontiers in Earth Science, 2023
Convolutional Neural Network (CNN) is widely used in seismic data denoising due to its simplicity and effectiveness. However, traditional seismic denoising methods based on CNN ignore multi-scale features of seismic data in the wavelet domain.

On the Interplay between Entropy and Robustness of Gene Regulatory Networks

open access: yesEntropy, 2010
The interplay between entropy and robustness of gene network is a core mechanism of systems biology. The entropy is a measure of randomness or disorder of a physical system due to random parameter fluctuation and environmental noises in gene regulatory ...
