OBSERVATIONS ON COMPRESSED AIR ILLNESS.

Compressed Air Illness, or So-Called Caisson Disease

was to inflate the tunnel, as you would blow up a bladder, by corking up one end with a huge brick wall twelve feet thick and pumping in additional atmospheres. At the sea level the pressure of the atmosphere is well known to be about fifteen pounds per square inch ; but into this air-tight chamber the engineers pumped sometimes as much as an additional thirtyfive pounds to the square inch, so ...

Compressed sensing with corrupted observations

We proposed a weighted l minimization: min , ‖x‖ + λ‖f‖ s.t.Ax+ f= b to recover a sparse vector x and the corrupted noise vector f from a linear measurement b = Ax + f when the sensing matrix A is an m × n row i.i.d subgaussian matrix. Our first result shows that the recovery is possible when the fraction of corrupted noise is smaller than a positive constant, provided that ‖x‖ ≤ O(n/ln (n/‖x ∗...

Compressed Sensing with Nonlinear Observations

Compressed sensing is a recently developed signal acquisition technique. In contrast to traditional sampling methods, significantly fewer samples are required whenever the signals admit a sparse representation. Crucially, sampling methods can be constructed that allow the reconstruction of sparse signals from a small number of measurements using efficient algorithms. We have recently generalise...
