Khapalov %T Mathematical problems motivated by environmental monitoring %X This paper introduces three estimation problems for parabolic systems: the estimation of the intensity of sources on the basis of available measurements, the estimation of the state of a distributed process through given observations and an inverse problem of multiobjective optimization whose solution allows to estimate the largest input levels that ensure a guaranteed system output performance. The motivations to the problems come from environmental monitoring issues. %P 529-534 %B IFAC Symposia Series - Proceedings of a Triennial World Congress %V 5 %C Tallinn, USSR %D 1990 %I IFAC %L iiasa13604
