We propose a sampling type method to image scatterer in an electromagnetic waveguide. The waveguide terminates at one end and the measurements are on other far field. imaging function is based integrating known over measurement surface directly. design analysis of such factorization data operator given by measurements. We show that peaks inside scatterer, where coer...

To deal with the problems of non response, one parameter classes of imputation techniques have been suggested and their corresponding point estimators have been proposed. The proposed estimator is more efficient than several other estimators. A design based approach is used to compare the proposed strategy with existing strategies. Theoretical results have been verified through empirical studie...

Abstract We solve the closed range problem for Volterra-type integral operator on Fock spaces. Several applications of result related to operators invertibility, Fredholm, and dynamical sampling structures from frame perspectives are provided. further prove a bounded preserves no property. On contrary, adjoint if only it is noncompact but fails preserve both tight frames Riesz basis.

In the present paper, our purpose is to obtain a nonlinear approximation by using convergence in ?-variation. Angeloni and Vinti prove some results considering linear sampling-type discrete operators. These types of operators have close relationships with generalized sampling series. By improving Vinti?s one, we aim get which also means summability process. We evaluate rate under appropriate Li...
