A system (or a given state of a system) can be characterized by the values taken by some physical quantities. A simple example would be a system that is represented by only two quantities, for instance, an electric conductivity σ and a frequency ν . Obviously, such a system could equivalently be represented by the electric resistivity ρ = 1/σ and the period τ = 1/ν . In order to better discuss the existence of these equivalent sets of physical quantities, let me start by introducing two different points of.inverse problems: exercices institut physique globe paris

Let x be a Cartesian coordinate and t be ordinary (Newtonian) time. When a pressure perturbation p( x, t) propagates in a medium where the velocity of the acoustic waves at point x is c( x ) , the pressure ﬁeld p( x, t) satisﬁes the well-known (one-dimensional) acoustic wave equation 1 ∂2 p ∂2 p ( x, t) − 2 ( x, t) = S( x, t) , (8.94) c( x )2 ∂t2 ∂x where S( x, t) is the source function, i.e., the function representing the excitation that produces the acoustic waves. So, the medium is characterized by the .inverse problems: exercices

Estimate the epicentral coordinates ( X, Y ) of the explosion, assuming a velocity of v = 5 km/s for the seismic waves. Discuss the generalization of the problem to the case where the time of the explosion, the locations of the seismic observatories, or the velocity of the seismic waves are not perfectly known.inverse problems: exercices
