Interventions causing genome modifications that can be passed on to descendants have been prohibited in France since 1994. New methods, such as CRISPR-Cas9, have been developed, raising questions about their potential use on human germline cells and embryos. The only acceptable medical indication would be to prevent the transmission of a disease gene to the child. However, the necessary conditi...

The paper presents the semi-active vibration control based on the Skyhook algorithm which benefits from the adaptively tuned inverse magnetorheological (MR) damper model. The structure of the inverse model consists of the atan function and a linear viscous damping component. The proposed algorithm was tested by simulation of the quarter-car suspension model subjected to multiple bump road excit...

The purpose of this paper is to present a new modified parametric algebraic model for MR damper in controlling the semi-active suspension system. Except for its accuracy, modified algebraic model is additionally more preferable in terms of its low computational expenses compared to differential modified Bouc-Wen’s model that is extremely computationally demanding. The control part consists of t...

Magnetorheological (MR) dampers have received special attention as semi-active devices for mitigation of structural vibrations. Because of the inherent nonlinearity of these devices, it is difficult to obtain a reasonable mathematical inverse model. This paper is concerned with two related concepts. On one hand, it presents a new inverse model of MR dampers based on the normalized Bouc–Wen mode...

Magnetorheological (MR) dampers are one of the most promising new devices for structural vibration reduction. Because of their mechanical simplicity, high dynamic range, low power requirements, large force capacity, and robustness, these devices have been shown to mesh well with application demands and constraints to offer an attractive means of protecting civil infrastructure systems against s...

Abstract Hysteresis widely exists in civil structures, and dissipates the mechanical energy of systems. Research on random vibration hysteretic systems, however, is still insufficient, particularly when excitation non-Gaussian. In this paper, radial basis function (RBF) neural network (RBF-NN) method adopted as a numerical to investigate Bouc-Wen system under Poisson white noise excitations. Th...
