Asymptotic analysis provides a set of powerful techniques for approximating solutions to differential equations, particularly in cases where exact solutions are elusive. This approach is critical when ...
SIAM Journal on Applied Mathematics, Vol. 74, No. 1 (2014), pp. 60-82 (23 pages) Theoretical models for the thermal response of vertical geothermal boreholes often assume that the characteristic time ...
The cross-correlations of ambient noise or earthquake codas are massively used in seismic tomography to measure the dispersion curves of surface waves and the travel times of body waves. Such ...
