Abstract
We consider a heat equation and a wave equation in a spatial interval over a time interval. This article deals with inverse problems of determining sizes of spatial intervals by extra boundary data of solutions of the governing equations. Under several different circumstances, we prove the uniqueness, the non-uniqueness and some size estimate. Moreover, we numerically solve the inverse problems and compute accurate approximations of the sizes. This is illustrated with satisfactory numerical experiments.
