Abstract We study the problem of determining minimum number $f(n,k,d)$ affine subspaces codimension $d$ that are required to cover all points $\mathbb{F}_2^n\setminus \{\vec{0}\}$ at least $k$ times while covering origin most $k - 1$ times. The case $k=1$ is a classic result Jamison, which was independently obtained by Brouwer and Schrijver for $d = . value $f(n,1,1)$ also follows from well-kno...

Abstract The effects of second-neighbor interactions in Kekulé-Y patterned graphene electronic properties are studied starting from a tight-binding Hamiltonian. Thereafter, low-energy effective Hamiltonian is obtained by projecting the high energy bands at ? point into subspace defined Kekulé wave vector. spectrum low excellent agreement with one numerical diagonalization full main effect secon...

A new guideline for proper allocation of multipoles in the multiple multipole method (MMP) is proposed. In an ‘a posteriori’ approach, subspace fitting (SSF) is used to find the best location of multipole expansions for the two dimensional dielectric scattering problem. It is shown that the best location of multipole expansions (regarding their global approximating power) coincides with the med...

Nowadays, most streaming data sources are becoming highdimensional. Accordingly, subspace stream clustering, which aims at finding evolving clusters within subgroups of dimensions, has gained a significant importance. However, existing subspace clustering evaluation measures are mainly designed for static data, and cannot reflect the quality of the evolving nature of data streams. On the other ...
