Abstract: In this study, we reconsider the torsion of nonlinear viscous shafts. Attention is paid to the analytical solution of the nonlinear partial differential equation arising in the problem's formulation, and it is concluded ...

Abstract: Color removal from cotton textile processing wastewater by addition of powdered activated carbon (PAC) into a lab-scale activated sludge system was examined. The activated sludge system was continuously operated in different ...

Abstract: This study is devoted to the investigation of the effects of inertial, centripetal, and Coriolis forces on the dynamic response of a simply supported beam with a single crack under moving mass load. As in the case of beams ...

Abstract: This paper presents a novel approach to mitigating Newtonian noise (NN) in laser interferometer gravitational wave observatory (LIGO) on Earth’s surface. The proposed method offers an unprecedented means to enhance the ...

Abstract: In this study, the analytical solution of the direct dynamics problem that mostly requires some numerical techniques is developed for two important cases. In the first case, two coupled differential equations of the motion ...

Abstract: The objective of this investigation is to examine the validity of applying the assumed modes method and the generalized impulse momentum approach that involves the coefficient of restitution in ...

Abstract: This study explores surface-wave propagation through periodic arrangements of multilayered piles in a single-layer soil medium from the viewpoint of bandgaps. The influence of the geometrical parameters of the model on the ...
