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 ...

Geometrical analysis and control optimization of a predator-prey model with multi state-dependent impulse

open access: yesAdvances in Difference Equations, 2017
In this paper, a predator-prey model with Holling type-I functional response and multi state impulsive feedback control is established, where the intensity of pesticide spraying and the release amount of natural enemies are linearly dependent on the ...

INCREASE OF INFORMATIVE CAPACITY OF ULTRA WIDE BAND IMPULSE SIGNALS

open access: yesInformation and Telecommunication Sciences, 2013
It is common to think that impulse radio ultra band signals (IR-UWB) in communication systems can carry the information at very high rates. But each impulse of the signal can carry just one bit of information.

Interception time and uncertainty optimization for tangent-impulse orbit interception problem

open access: yesDefence Technology, 2022
The traditional tangent impulse interception problem does not consider the influence of actual deviation. However, by taking the actual state deviation of the interceptor into the orbit design process, an interception orbit that is more robust than the ...

Influence of High Current-Density Impulses on the Stress-Strain Response and Microstructural Evolution of the Single Crystal Superalloy CMSX-4 [PDF]

open access: yesMaterials Research, 2018
Owing to the low formability of single-crystal nickel-based materials, single-crystal components are typically cast. Subsequently, a multi-stage heat treatment is carried out in order to partially compensate the dendrite segregation and to stabilize the ...

Auralization based on multi-perspective ambisonic room impulse responses

open access: yesActa Acustica, 2020
Most often, virtual acoustic rendering employs real-time updated room acoustic simulations to accomplish auralization for a variable listener perspective.

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

Surrogate impulse ground motion for practical simulation of critical nonlinear structural responses

open access: yesFrontiers in Built Environment
Impulse-based representations of earthquake ground motions provide an efficient framework for evaluating critical nonlinear structural responses. However, the direct use of ideal impulse ground motions expressed by Dirac’s delta function may excite all ...

Application of Machine Learning for the Spatial Analysis of Binaural Room Impulse Responses

open access: yesApplied Sciences, 2018
Spatial impulse response analysis techniques are commonly used in the field of acoustics, as they help to characterise the interaction of sound with an enclosed environment.

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.
