Low-temperature spin-glass behaviour in a diluted dipolar Ising system
(2015-07-27)Using Monte Carlo simulations, we study the character of the spin-glass (SG) state of a site-diluted dipolar Ising model. At high dilution, well deep in the SG phase, we find spiky distributions that are strongly ... -
Mean-preserving interpolation with splines for solar radiation modeling
(Elsevier, 2022-11-17)Interpolation is a fundamental process in solar resource assessment that glues consecutive components of the modeling chain. Most interpolation techniques assume that the interpolating function must go through the interpolation ... -
