WebThe fraction of non-180° switching in each grain is obtained through a dichotomy approximation. Selected numerical results show that during electrical poling, 180° switching is usually complete ... WebHere, x 0 (t) is the zero approximation for the coordinate of the localization point of the reaction front at time t. The methods of asymptotic analysis allow us to write out the following problem for determining the principal term x 0 (t) of the asymptotic approximation in terms of the small singular parameter ε of the exact position x t. p. (t):

WebIn this paper, we study the uniform Diophantine approximation in the nonautonomous dynamic system generated by the Cantor series expansions, which is formulated by considering the following set: { x ∈ [ 0, 1): ∀ N ≫ 1, there is an integer n ∈ [ 1, N], such that T Q n x ≤ ( q 1 q 2 ⋯ q N) − v }. It is of Hausdorff dimension ( 1 − ... WebWhen it fails, the problem is NP-hard and, in fact, APX-complete (hence, cannot be approximated better than some constant). Thus, we establish a dichotomy in the complexity of computing an optimal S-repair. We present general analysis techniques for the complexity of computing an optimal U-repair, some based on the dichotomy for S-repairs. camper trailers under $5000
