A new stabilized least-squares imaging condition
(2009)
The classical deconvolution imaging condition consists of dividing the upgoing wave field by the downgoing wave field and summing over all frequencies and sources. The least-squares imaging condition consists of summing ...
A fast method of computing group-velocity partial derivatives for Love waves propagating in a layer on a half-space
(1999)
The dispersion relation for Love waves in a layer on a half-space is modified by introducing the wave number and its square instead of the phase velocity. The implicit function theorem is then used to derive the analytical ...

Determination of sulfur compounds in gasoline using mercury film electrode by square wave voltammetry
(Elsevier B.V., 2008-06-01)
A sensitive method based on square wave voltammetry is described for the quantitative determination of elemental sulfur, disulfide and mercaptan in gasoline using a mercury film electrode. These sulfur compounds can be ...
