Velocity-squared dampingStructural-vibration controlReal-time hybrid simulationHigh-rise buildingsWind-induced excitationHybrid mass dampers (HMDs), which integrate tuned mass dampers with active mass dampers (AMDs) mounted on top, have been employed for vibration control in high-rise buildings. However,...
Acceleration always has direction because it has velocity. This makes it a vector quantity with dimensions of length and time. It is measured in metres per second squared (m/s2). Because acceleration is a vector quantity, any change in direction also causes changes in acceleration. Positive and...

In this case, the vortex mass is a proportionality coefficient between the moving vortex energy and its squared velocity and reflects the energy increase due to the vortex dynamic profile deformations. Usually the mass in magnetism is introduced by analogy to the effective mass of Bloch electrons ...
Multiply the length of time the object has been falling by 9.8 meters per second squared. For example, if an object has been in free-fall for 10 seconds, then it would be: 10 x 9.8 = 98 meters per second. Subtract your result from the object's initial upward velocity. For example, ...

The mean squared error (MSE), coefficient of determination (R), and margin of deviation (MoD) are calculated using the following mathematical formulas: \text{MSE}=\frac{1}{\text{N}}\sum_{\text{i}=1}^{\text{N}}{({\text{X}}_{\text{targ}(\text{i})}-{\text{X}}_{\text{pred...
What metric unit do we use to denote velocity? What SI unit is used to measure mechanical energy? What is the weight of a 40-kg mass? What measurement changes based on the strength of gravitational force? What would be the best tool to measure the amount of matter in an object?
The resulting streaming motions are supersonic, with a root-mean-squared (RMS) velocity of roughly 30 km s–1 at the end of the recombination epoch, and a coherence length of several comoving Mpc. At lower redshifts, the RMS velocity of the streaming motions declines as vRMS∝ (1 + z...
The potential required to just prevent an ion from traversing through it is proportional to the relative velocity squared hence the factor of nine. Although the present invention has been described with reference to preferred embodiments, it will be understood by those skilled in the art that ...
