They show considerable potential in many applications, including vibration insulation, wave-guiding, noise control, and energy harvesting technologies. While the foundation of metamaterials research ...

This paper proves the modal vibration properties of general rotating, cyclically symmetric (or rotationally periodic) systems, including those with central components to which cyclically symmetric ...

THE development of high-speed mechanical engines and similar devices has, during the last decade, brought forth a demand for both recording vibration amplitudes with accuracy and the analysis of such ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

Disruption of a payload can be caused by three of the primary sources of vibration (or noise): ground vibration, acoustic noise, and direct force disturbances. Ground, or seismic vibration, is present ...

One hundred fifty years after Russian chemist Dmitri Mendeleev published his system for neatly arranging the elements, the periodic table it gave birth to hangs in every chemistry classroom in the ...
