APPLICATION OF DARBOUX TRANSFORMATION TO MULTIDIMENSIONAL INHOMOGENEOUS PROBLEMS
TASK Quarterly, 2016 General properties of ladder operators applied to inhomogeneous problems are studied in the context of their usefulness for solving practical problems with stress put on the possibility of embedding the interwine relation onto a wider class of operators.

Computational Methods for Multidimensional Neutron Diffusion Problems
Science and Technology of Nuclear Installations, 2009 A neutronic module for the solution of two-dimensional steady-state multigroup diffusion problems in nuclear reactor cores is developed. The module can produce both direct fluxes as well as adjoints, that is, neutron importances.

On the Truncated Multidimensional Moment Problems in
Axioms, 2022 We consider the problem of finding a (non-negative) measure μ on B(Cn) such that ∫Cnzkdμ(z)=sk, ∀k∈K. Here, K is an arbitrary finite subset of Z+n, which contains (0,…,0), and sk are prescribed complex numbers (we use the usual notations for multi ...

General Stieltjes moment problems for rapidly decreasing smooth functions [PDF]
, 2017 We give (necessary and sufficient) conditions over a sequence $\left\{ f_{n}\right\} _{n=0}^{\infty}$ of functions under which every generalized Stieltjes moment problem \[ \int_{0}^{\infty} f_{n}(x)\phi(x)\mathrm{d} x=a_{n}, \ \ \ n\in\mathbb{N}, \] has

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017 In early works the author studied the Dirichlet and Poincaré problems for multidimensional hyperbolic equations, which shows the well-posedness of these problems in cylindrical domains, significantly dependent on the height of the considered cylindrical ...

A variational nodal formulation for multi-dimensional unstructured neutron diffusion problems
Nuclear Engineering and Technology, 2023 A variational nodal method (VNM) with unstructured-mesh is presented for solving steady-state and dynamic neutron diffusion equations. Orthogonal polynomials are employed for spatial discretization, and the stiffness confinement method (SCM) is ...

THE ADDITIVE CONSTANT PROBLEM IN MULTIDIMENSIONAL SCALING [PDF]
ETS Research Bulletin Series, 1954 ABSTRACTThe problem of choosing the correct additive constant to convert relative inter‐stimulus distances to absolute inter‐stimulus distances in multidimensional scaling is investigated. An artificial numerical example is constructed and various trial values of the constant are inserted to demonstrate the effect on the multidimensional map of making ...
