With the continuous development of power grids, scale supercomputing clusters has also gradually increased to carry a large number system simulation calculations, and problem high energy consumption appeared. To solve this problem, we propose container virtualization-based cluster for system. We analyze impact containers on calculations compare effects various scheduling migration algorithms clusters. Experiments show that compared virtual machines with hypervisor, which consumes massive...

Blind source separation (BSS) is an active research topic in the fields of biomedical signal processing and brain–computer interface. As a representative technique, maximum fraction analysis (MSFA) has been recently developed for problem BSS. However, MSFA formulated based on L2-norm, thus prone to be negatively affected by outliers. In this study, authors propose robust alternative L1-norm, termed as MSFA-L1. Specifically, they re-define objective function MSFA, which energy quantities both...

Let $\Omega\subset \mathbb{R}^4$ be a smooth bounded domain, $W_0^{2,2}(\Omega)$ the usual Sobolev space. For any positive integer $\ell$, $\lambda_{\ell}(\Omega)$ is $\ell$-th eigenvalue of bi-Laplacian operator. Define $E_{\ell}=E_{\lambda_1(\Omega)}\oplus E_{\lambda_2(\Omega)}\oplus\cdots\oplus E_{\lambda_{\ell}(\Omega)}$, where $E_{\lambda_i(\Omega)}$ eigenfunction space associated with $\lambda_i(\Omega)$. $E^{\bot}_{\ell}$ denotes orthogonal complement $E_\ell$ in $W_0^{2,2}(\Omega)$....
