The Optimal Inhomogeneity for Superconductivity: Finite Size Studies
We report the results of exact diagonalization studies of Hubbard models on a 4 × 4 square lattice with periodic boundary conditions and various degrees and patterns of inhomogeneity, which are represented by inequivalent hopping integrals t and t′. We focus primarily on two patterns, the checkerboard and the striped cases, for a large range of values of the on-site repulsion U and doped hole c...
متن کاملFinite-size Effects in Fluxon Scattering by an Inhomogeneity
The interaction of a fluxon with a finite-size inhomogeneity in a long Josephson junction is studied within the framework of the perturbation theory for solitons. The threshold values of the bias current density either for capture of the fluxon or for its escape on the inhomogeneity are calculated. Induced by the resonant fluxon emission hystereses on the first zero-field step of the Josephson ...
متن کاملOptimal Earthmoving Fleet Size for Minimising Emissions and Cost
Traditionally, the earthmoving operations have been developed based on the minimum cost per production criterion. Nowadays, due to the negative impacts of the emissions on the environment, there is an increasing public awareness to reduce the emissions from the earthmoving operations. Different management strategies can be employed to reduce emissions, amongst other things, which can also resul...
متن کاملInhomogeneity Image Segmentation with Optimal Spatial Scale
A novel local region-based active contour model is proposed to segment medical images with intensity inhomogeneities and various noises. The contribution of the proposed work is twofold. First, the anisotropy of evolution contours is exploited to characterize the local classification information around each pixel. Integrating it with local gray intensity information, the new model stabilizes th...
متن کاملComparing two Formulas of Sample Size Determination for Prevalence Studies
Background and purpose: Sample size and its determination is one of the most important problems in health researches. Calculating sample size for prevalence studies is one of the common questions of sample size topics. Minimum sample size with least complexity is desirable in order to achieve the basic goal of these studies. This study aims to compare two formulas of sample size calculation for...
