In this paper we address the issue of workload decomposition in programming hierarchical distributedshared memory parallel systems. The workload decomposition we have devised consists of a two-stage procedure: a higher-level decomposition among the computational nodes; and a lower-level one among the processors of each computational node. By focusing on porting of a case study particle-in-cell ...

As it is known, groups of correlated 2D images of various kind could be represented as 3D images, which are mathematically described as 3 rd order tensors. Various generalizations of the Singular Value Decomposition (SVD) exist, aimed at the tensor description reduction. In this work, new approach is presented for 3 rd order tensor decomposition, where unlike the famous methods for decompositio...

this study examins effects of trade liberalization on the wage inequality across industries and between genders within these industries by utilizing the data of micro-level households’ income and expenditures surveys and trade statistics over 2001-2011. the analysis is carried based on the heckscher–ohlin’s theory in international trade and baker’s taste discrimination theory at firms. we use q...

This paper presents a new parallel mesh generation method leading to subdomains of shape well-suited Schur based domain decomposition methods such as the FETI and BDD solvers. Starting from coarse mesh, meshes are created in through hierarchical refinement morphing techniques. The proposed methodology aims at limiting occurrence known pathological situations (jagged interfaces, misplaced hetero...

Lithium-ion battery electrode-level online state estimation using high-fidelity nonlinear electrochemical models remains a key challenge. This is particularly due to weak observability inherited from the complex model structure, even for reduced-order models. letter presents systematic and rigorous strategy analyze local of single particle (SPM) with both electrodes, which commonly known be loc...
