Nonlinear Finite Element Analysis for Punching Shear Resistance of Steel Fibers High Strength Reinforced Concrete Slabs [PDF]

open access: yesEngineering and Technology Journal, 2014
This study is devoted to investigate the punching shear resistance of high strength reinforced concrete slabs with steel fibers by using the well-known (P3DNFEA), a non-linear finite element program for three-dimensional analysis of reinforced concrete ...

Non-linear echo cancellation - a Bayesian approach [PDF]

open access: yes, 2009
Echo cancellation literature is reviewed, then a Bayesian model is introduced and it is shown how how it can be used to model and fit nonlinear channels. An algorithm for cancellation of echo over a nonlinear channel is developed and tested.

Evaluation of the Microsoft Excel Solver Spreadsheet-Based Program for Nonlinear Expressions of Adsorption Isotherm Models onto Magnetic Nanosorbent

open access: yesApplied Sciences, 2021
The sorption of basic dyes onto magnetic nanosorbent is commonly used as a novel material to combat powdered activated carbon, which is difficult to handle and separate during water and wastewater treatment. This adsorption method is commonly implemented

Breaking the mass law for broadband sound insulation through strongly nonlinear interactions

open access: yesNew Journal of Physics, 2023
Sound transmission through panels is governed by the well-known mass law in the mid-frequency range. This paper reveals a possibility of breaking this density-dominant law through strongly nonlinear interaction, while broadening the bandwidth for ...

Bifurcation Analysis and Chaos Control of a Fractional Order Portal Frame with Nonideal Loading Using Adaptive Sliding Mode Control

open access: yesShock and Vibration, 2017
We investigate the chaotic oscillations in a fractional order model of a portal frame with nonideal loading. The bifurcation of the fractional order portal frame system for parameters and fractional orders are investigated. Bicoherence analysis shows the

A Low-Complexity Volterra Filtered-Error LMS Algorithm with a Kronecker Product Decomposition

open access: yesApplied Sciences, 2021
Nonlinear active control is very important in many practical applications. Many well-known nonlinear active noise control algorithms may suffer from high computational complexity and low convergence speed, especially in the nonlinear secondary path case.
