Free air correction (gravity)
Modelling? (everything :-) )
Wave propagation (mostly seismics)

Free air correction (gravity) is correct! Since you have to pay to use the air pump, the "free air" sign apparently should be "corrected". So the answer is "Free-air Correction". It's a term used in gravity data reduction for the compensation of altitude.

:!:
The picture shows a wave with the shape of hearts, so the answer is "Love Wave". In geophysics, Love wave is a surface wave polarized horizontally with its particle movements perpendicular to the direction of wave propagation.

It reminders me a Twitter message by Dr. Lucy Jones above love wave:

Worst seismology joke: A seismologist investigated strange signals showing up at a seismic station and found a couple making Love waves.

1) Free Air Correction (Gravity)
2) Secondary Wave (Vs)
3) Love Wave

Finally, all answers are out! :lol:

For the second one, combined with GuyM's answer, you got it right!

Vs is the conventional notation for shear wave (secondary wave) velocity. With modeling going on in the fashion show, the answer is "Shear Wave Velocity Modeling". For shear wave velocity modeling, multichannel analysis of surface waves (MASW) has becoming more and more popular for geotechnical investigations.
