A New Multi-Layered Fuzzy Image Filter for Removing Impulse Noise [PDF]

open access: yesJournal of Systemics, Cybernetics and Informatics, 2003
In this paper we develop a fuzzy image .lter which consists of a multi-layered fuzzy structure based on the weighted fuzzy blend filter for the removal of noise from images heavily corrupted by impulse noise, while preserving the intricate details of the

A micromechanical modelling approach for predicting particle dislodgement [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2015
In recent years, the impulse and energy concepts have been proposed as a means of improving the prediction of sediment particle entrainment. Because they account for temporal aspects of the applied hydrodynamic forces, impulse-based or energy-based ...

Shock wave and bubble characteristics of underwater array explosion of charges

open access: yesDefence Technology, 2022
In this study, we focused on the effect of the underwater explosion parameters of multi-point array explosion. The shock wave and bubble parameters of aggregate charge, two charges, and four charges were measured through an underwater explosion test, and

Synergistic Effects of Depression and Poor Impulse Control on Physical Partner Violence; A National Study in the United States [PDF]

open access: yesInternational Journal of Epidemiologic Research, 2017
Background and aims: Although major depressive disorder (MDD) also increases the risk of intimate partner violence (IPV) perpetration, poor mental health has been mostly conceptualized as a consequence of IPV victimization rather than a risk factor for ...

Low rank prior in single patches for non-pointwise impulse noise removal [PDF]

open access: yes, 2015
This paper introduces a low rank prior in small oriented noise-free image patches: Considering an oriented patch as a matrix, a low-rank matrix approximation is enough to preserve the texture details in the optimally oriented patch.

Reference values of impulse oscillometric lung function indices in adults of advanced age. [PDF]

open access: yes, 2013
Impulse oscillometry (IOS) is a non-demanding lung function test. Its diagnostic use may be particularly useful in patients of advanced age with physical or mental limitations unable to perform spirometry.

Polar Codes and a M-ary Modulation-Based OFDM-PLC System

open access: yesInformation, 2023
Power Line Communication (PLC) serves as a medium for communication over power lines, utilizing the existing power grid for information transmission. It offers a low-cost, highly scalable signal transmission method and has the potential to become the ...

Multi-harmonic impulse cavity [PDF]

open access: yesProceedings of the 1999 Particle Accelerator Conference (Cat. No.99CH36366), 2003
A method that may enable very high gradient acceleration is proposed. A short impulse shape wave form can be generated by superposition of many harmonics. It is achieved by a cavity with multi-harmonic resonances, which may have ten or more modes excited simultaneously with proper phases.

Critical response of elastic-plastic SDOF systems with nonlinear viscous damping under simulated earthquake ground motions

open access: yesHeliyon, 2019
Multi impulse with constant time interval is used as a representative of a long-duration earthquake ground motion. An analytical expression is derived for the elastic-plastic response of a single-degree-of-freedom (SDOF) model with nonlinear viscous ...

Hybrid Impulsive Pinning Control for Mean Square Synchronization of Uncertain Multi-Link Complex Networks with Stochastic Characteristics and Hybrid Delays

open access: yesMathematics, 2023
This study explores the synchronization issue for uncertain multi-link complex networks incorporating stochastic characteristics and hybrid delays. Unlike previous works, internal delays, coupling delays, and stochastic delays considered in our model ...
