The Forward Operator and Its Conjugatea
نویسندگان
چکیده
We present a phase shift datuming and migration algorithm for the data acquired on a nonnat surface. First of all, we formulate the exploding reeector modeling scheme for a nonnat recording surface. Then, the migration scheme is found as the conjugate operator of the modeling operator. In order to get the correct migration and datuming operators, the forward modeling must be physically reasonable because the conjugate operators are strongly dependent on the forward modeling operator. The artifacts caused by the non-unitary property of the operators can be reduced by a least-squares optimization technique.

POWERSET OPERATOR FOUNDATIONS FOR CATALG FUZZY SET THEORIES
The paper sets forth in detail categorically-algebraic or catalg foundations for the operations of taking the image and preimage of (fuzzy) sets called forward and backward powerset operators. Motivated by an open question of S. E. Rodabaugh, we construct a monad on the category of sets, the algebras of which generate the fixed-basis forward powerset operator of L. A. Zadeh. On the next step, w...
متن کامل2D DC resistivity forward modeling based on the integral equation method and a comparison with the RES2DMOD results
A 2D forward modeling code for DC resistivity is developed based on the integral equation (IE) method. Here, a linear relation between model parameters and apparent resistivity values is proposed, although the resistivity modeling is generally a nonlinear problem. Two synthetic cases are considered for the numerical calculations and the results derived from IE code are compared with the RES2DMO...
متن کاملOperator-valued tensors on manifolds
In this paper we try to extend geometric concepts in the context of operator valued tensors. To this end, we aim to replace the field of scalars $ mathbb{R} $ by self-adjoint elements of a commutative $ C^star $-algebra, and reach an appropriate generalization of geometrical concepts on manifolds. First, we put forward the concept of operator-valued tensors and extend semi-Riemannian...
متن کاملA Forward-Backward Projection Algorithm for Approximating of the Zero of the Sum of Two Operators
In this paper, a forward-backward projection algorithm is considered for finding zero points of the sum of two operators in Hilbert spaces. The sequence generated by algorithm converges strongly to the zero point of the sum of an $alpha$-inverse strongly monotone operator and a maximal monotone operator. We apply the result for solving the variational inequality problem, fixed po...
