A study of the performance of Neville elimination using two kinds of partitioning techniques

In this paper, a method to compute the solution of a system of linear equations by means of Neville elimination is described using two kinds of partitioning techniques: Block and Block-striped.  ...  On the other hand, the overall parallel run time of Neville elimination is better than Gauss time as Neville elimination uses a lower cost communication model.  ...  In the case of columnwise block striping, the results obtained are similar to the costs achieved by other authors (see [9] ) for the Gaussian method.  ...

To address the issue of noise in manufacturing environments, we developed a VR-supported method allowing users to explore noise behavior.  ...  In a real-world factory, the acoustic measurements obtained essential input data for simulation settings and validation data for simulation results.  ...  In our method, the sparse principal components (SPCs) are computed using an iterative elimination strategy (Wang and Wu [16] ) with project deflation to eliminate the influence of a pseudo-eigenvector  ...
