This article presents the forced vibration of composite beams reinforced by single-walled carbon nanotubes (SWCNTs) and subjected to a moving mass. Considering distribution such as uniform (UD-CNT), functionally graded Λ (FGΛ-CNT) X (FGX-CNT), three different are studied. Based on third-order shear deformation theory (TSDT), motion equations derived using Hamilton's principle. Including mass in...

Context. Solar eruptions, such as coronal mass ejections (CMEs), are often accompanied by accelerated electrons that can in turn emit radiation at radio wavelengths. This is observed solar bursts. The main types of bursts associated with CMEs type II and IV sometimes show movement the direction CME expansion, either radially or laterally. However, propagation respect to has only been studied fo...

We investigate the evaporation of an uncharged and non-rotating black hole (BH) in vacuum, by taking into account effects given shrinking horizon area. These include back-reaction on metric other smaller contributions arising from quantum fields curved spacetime. Our approach is facilitated use analog accelerating moving mirror. study consequences this modified BH entropy. Insights are provided...

Models of the vertical apparent mass of the human body are mostly restricted to a sitting posture unsupported by a backrest and ignore the variations in apparent mass associated with changes in posture and changes in the magnitude of vibration. Using findings from experimental research, this study fitted a single degree-of-freedom lumped parameter model to the measured vertical apparent mass of...
