Webables of a fluctuating system vary randomly in time, with character istic amplitudes determined by the" fluctuation intensity. When the system is also driven by a sinusoidal force, a periodic component arises in the time evolution of the dynamical variables at the same frequency as the force, superimposed on-their random variation in time. WebSep 1, 2024 · Igor et al. investigated the rocking Markovian ratchets [36] and fluctuating tilt ratchets [37] in sticky viscoelastic medium with the characteristic of power-law memory, and it is observed that sub-diffusive current could transport in the counterintuitive direction, with the change of thermal fluctuations or driving force.
WebThe transmissibility is the ratio of the maximum value of the force transmitted to the foundation to the maximum value of the force applied to the machine element. A machine element supported by springs and connected to a dashpot is subjected to a …
Weba. The spring force is the opposite direction to a compression (as it is for an extension), so the work it does is negative. b. The work done depends on the square of the displacement, which is the same for x = ± 6 cm x = ± 6 cm, so the magnitude is 0.54 J. WebJan 29, 2010 · The long-time behavior of the first moment for the output signal of a fractional oscillator with fluctuating frequency subjected to an external periodic force is considered. Colored fluctuations of the oscillator eigenfrequency are modeled as a dichotomous noise. The viscoelastic type friction kernel with memory is assumed as a power-law function of …

The electron distribution around an atom or molecule undergoes fluctuations in time. These fluctuations create instantaneous electric fields which are felt by other nearby atoms and molecules, which in turn adjust the spatial distribution of their own electrons. The net effect is that the fluctuations in electron … See more London dispersion forces (LDF, also known as dispersion forces, London forces, instantaneous dipole–induced dipole forces, fluctuating induced dipole bonds or loosely as van der Waals forces) are a type of See more The first explanation of the attraction between noble gas atoms was given by Fritz London in 1930.
