  2. Isolation tank - Wikipedia

    en.wikipedia.org/wiki/Isolation_tank

    The tank is filled with 10 inches (25 cm) of water which contains enough dissolved Epsom salt to create a specific gravity of approximately 1.25–1.26, enabling a person to float freely with their face above the water. In order to reduce thermal sensations, the water in the float tank is maintained at approximately skin temperature, around 35 ...

  3. Computation of radiowave attenuation in the atmosphere

    en.wikipedia.org/wiki/Computation_of_radiowave...

    The previous point of view of worst case leads to an elevation angle of −1.87-degree and an attenuation of 170.77 dB. With this kind of attenuation, every system would be unusable! It was found also for this case that with the nominal elevation angle, the distance of the tangent point to ground is 5.84 km; that of the worst case is 2.69 km.

  4. Free-space path loss - Wikipedia

    en.wikipedia.org/wiki/Free-space_path_loss

    In telecommunications, the free-space path loss (FSPL) (also known as free-space loss, FSL) is the attenuation of radio energy between the feedpoints of two antennas that results from the combination of the receiving antenna's capture area plus the obstacle-free, line-of-sight (LoS) path through free space (usually air).

    en.wikipedia.org/wiki/Vibration_isolation

    Another technique used to increase isolation is to use an isolated subframe. This splits the system with an additional mass/spring/damper system. This doubles the high frequency attenuation rolloff, at the cost of introducing additional low frequency modes which may cause the low frequency behaviour to deteriorate. This is commonly used in the ...

    The Panther KF51 (KF is short for German "Kettenfahrzeug" lit. ' tracked vehicle ') is a German fourth-generation main battle tank (MBT) that is under development by Rheinmetall Landsysteme (part of Rheinmetall's Vehicle Systems division).

    Donald Trump’s pick for defense secretary, Pete Hegseth, said gay people should be able to serve in the US military in an apparent shift from his previous stance on the issue.

  9. Attenuation - Wikipedia

    en.wikipedia.org/wiki/Attenuation

    The attenuation in the signal of ground motion intensity plays an important role in the assessment of possible strong groundshaking. A seismic wave loses energy as it propagates through the earth (seismic attenuation). This phenomenon is tied into the dispersion of the seismic energy with the distance. There are two types of dissipated energy:
