Web9 apr. 2024 · The effect of angles of attack (α) on the fluid–structure coupling of a flexible membrane wing is investigated experimentally at Re = 6 × 104. Membrane deformations and the surrounding flow fields are measured synchronously by two-dimensional time-resolved particle image velocimetry (2D-TRPIV). Results show that, for 12 ≤ α ≤ 16°, the vertical … Web1 dec. 2024 · In 2024 Nikiforov (2024) merged the A- and Q-spectral theories to proposed the Aα matrix: Aα (G)=αD (G)+ (1−α)A (G), α∈ [0,1]. Its largest eigenvalue is called the Aα-index of G. In this...
Web20 jun. 2024 · The Aα matrix of G is specified as Aα(G) = αD(G) + (1 − α)A(G), α ∈ [0, 1], where D(G) is the diagonal matrix of vertex degrees while A(G) is the adjacency matrix of G. In this article, we investigate the Aα matrix for commuting graphs of finite groups and we also find the Aα eigenvalues of the dihedral, the semidihedral and the dicyclic groups.

For 0 ≤ α < 1 and a k -uniform hypergraph H, the tensor Aα ( H) associated with H is defined as Aα ( H) = αD ( H) + (1 − α) A ( H ), where D (ℋ) and A ( H) are the diagonal tensor of degrees and the adjacency tensor of H, respectively. The α-spectra of H is the set of all eigenvalues of Aα ( H) and the α-spectral radius ...
