A research article published by the Beijing Institute of Technology presented a piezoelectric energy harvester (PEH) weighing only 46 milligrams. By ...

“It is not the first system based on a vibration mechanism but it is ... DC motor reached the rotational speed of the first natural frequency, a large amplitude of vibrations was induced on ...

We have learned that an effective way to passively control vibration is through the usage of a "vibration absorber". A typical vibration absorber is a single-DOF spring/mass/dashpot system that is ...

For effective vibration isolation, it is desirable to increase the frequency ratio r to a value much larger than sqrt(2) by either reducing the stiffness of the system or increasing its mass. This is ...

The MK26 Series Vibration Control Workstation with more ergonomic comfort is designed specifically for ultra-low natural frequency applications. The system utilizes MinusK patented negative ...

Raising your vibration is not just about positive ... 5. Spend time in natural light – Sunlight carries the frequency of the Solar Logos, the divine intelligence of our Sun, which radiates ...

India's earthquake monitoring agency NCS said the temblor that struck Myanmar and Thailand Friday afternoon caused severe damage because its shaking frequency matched the natural vibration of ...

Another major reason for the damage was that the earthquake's shaking frequency matched the natural vibration of buildings, making them more vulnerable, the NCS said. "The rupture direction is ...

INCOIS detects quake in Myanmar, no tsunami threat Another major reason for the damage was that the earthquake's shaking frequency matched the natural vibration of buildings, making those more ...
