Web12 apr. 2024 · Resistivity inversion plays a significant role in recent geological exploration, which can obtain formation information through logging data. However, resistivity inversion faces various challenges in practice. Conventional inversion approaches are always time-consuming, nonlinear, non-uniqueness, and ill-posed, which can result in an inaccurate … Web22 mei 2000 · V. B.

Google Scholar WebExamples of Ill Posed Problems. One simple example of an ill-posed problem is given by the equation y′ = (3/2)y 1/3 with y(0) = 0. Since the solution is y(t) = ± t 3/2, the solution is not unique (it could be plus t 3/2 or it could be minus t 3/2). As this violates rule 2 of the Hadamard criteria, the problem is ill posed. temporal resolution in fmri
