Development of an Adjoint Flux Calculation Technique for Exact Perturbation Theory in Monte Carlo Code MCS [PDF]
EPJ Web of ConferencesA calculation technique computing the adjoint flux of perturbed system is developed for the exact perturbation theory in Monte Carlo transport. By using a correlated sampling and iterated fission probability methods together, the adjoint flux of ...

Journal of Low Frequency Noise, Vibration and Active Control, 2018 The partial eigenvalue (or natural frequency) assignment or placement, only by the stiffness matrix perturbation, of an undamped vibrating system is addressed in this paper. A novel and explicit formula of determining the perturbating stiffness matrix is

Perturbation Methods for the Eigencharacteristics of Symmetric and Asymmetric Systems
Shock and Vibration, 2018 Dynamic analysis for a vibratory system typically begins with an evaluation of its eigencharacteristics. However, when design changes are introduced, the eigensolutions of the system change and thus must be recomputed.

The Fréchet Derivative of an Analytic Function of a Bounded Operator with Some Applications
International Journal of Mathematics and Mathematical Sciences, 2009 The main result in this paper is the determination of the Fréchet derivative of an analytic function of a bounded operator, tangentially to the space of all bounded operators. Some applied problems from statistics and numerical analysis are included as a

A Note on Certain Classes of Retro Banach Frames [PDF]
Sahand Communications in Mathematical Analysis, 2023 A new class of retro Banach frames called retro bi-Banach frame has been introduced and studied with illustrative examples. Relationships of a retro bi-Banach frame with various existing classes of Banach frame are presented.

Principal Eigenvalues and Perturbation
, 1995 In a classical article, Hess and Kato [HK] study the problem $$\left\{ {\begin{array}{*{20}{c}} {Au + \lambda mu = 0} \\ {0 \leqslant u \in D\left( A \right), u \ne 0,} \end{array}} \right.$$ (0.1) where A is a strongly elliptic operator on a bounded open set Ω of R n with Dirichlet boundary conditions and m is a continuous bounded function ...

Perturbations of symmetric eigenvalue problems
Applied Mathematics Letters, 2002 AbstractBy use of a cut-off technique, we obtain a result of multiple solutions to perturbations of symmetric eigenvalue problems with constraint such as — Δu = λ(f(x, u)+εg(x, u)) in Ω, u|∂Ω = 0, ∫Ω |∇ u|2 dx = r2.
