A Multiscale Pyramid Transform for Graph Signals [PDF]
, 2015 Multiscale transforms designed to process analog and discrete-time signals and images cannot be directly applied to analyze high-dimensional data residing on the vertices of a weighted graph, as they do not capture the intrinsic geometric structure of ...

Comparison of ENDF/B-VII.1 and JEFF-3.2 in VVER-1000 operational data calculation
EPJ Web of Conferences, 2017 Safe operation of a nuclear reactor requires an extensive calculational support. Operational data are determined by full-core calculations during the design phase of a fuel loading.

A Stable Condition and Adaptive Diffusion Coefficients for the Coarse-Mesh Finite Difference Method
Frontiers in Energy Research, 2022 Coarse-mesh finite difference (CMFD) method is a widely used numerical acceleration method. However, the stability of CMFD method is not good for the problems with optically thick regions. In this paper, a stability rule named the “sign preservation rule”

Development of an Analytic Nodal Diffusion Solver in Multigroups for 3D Reactor Cores with Rectangular or Hexagonal Assemblies. [PDF]
, 2009 More accurate modelling of physical phenomena involved in present and future nuclear reactors requires a multi-scale and multi-physics approach. This challenge can be accomplished by the coupling of best-estimate core-physics, thermal-hydraulics and ...
