In this article, we consider the one-dimensional inverse source problem for Helmholtz equation with attenuation (damping) factor in a one layer medium. We establish a stability by using multiple frequencies at the two end points of the domain which contai... see more

In this paper, we are investigating the one dimensional inverse source problem for Helmholtz equation where the source function is compactly supported in our domain. We show that increasing stability possible using multi-frequency wave at the two endpoint... see more

In the paper, we consider all possible subsets of the set of potential roots forming in some situations semi-lattices, by intersection and / or by union. Such structures arise in two similar problems in the theory of formal languages. Specifically, for so... see more

Baghdad City suffers from a continual horizontal urban expansion causing a multitude of urban problems that limit sustainable development. This paper presents an applied study to monitor the stages of urban sprawl of the Al-Zawra area, located on the outs... see more

The inverse problems for dierential equations are investigated, the solutionsof which do not use information about the exact characteristics of the physical process. Such inverse problems have not yet become widespread, but they are of great practica... see more
