We study the almost Mathieu operator: 1) + cos(2n +)u(n), on l 2 (Z), and show that for all ; , and (Lebesgue) a.e. , the Lebesgue measure of its spectrum is precisely j4 ? 2jjj. In particular, for jj = 2 the spectrum is a zero measure cantor set. Moreover, for a large set of irrational 's (and jj = 2) we show that the Hausdorr dimension of the spectrum is smaller than or equal to 1=2.

Smart homes with zero energy as an option to combine a large number of distributed energy resources to power networks in building a new future designs, are used. Zero energy homes equipped with smart power integrated production and consumption of zero over a year. In this study is that the sources of energy supply management program for a zero-energy home using mixed integer programming techniq...

background : to prepare safe and adequate blood supply to meet patients’ needs and ensure a sufficient number of regular blood donors, knowledge about factors encouraging people to donate blood regularly is essential. considering its importance, we aimed to identifying the effective factors of the return to blood donation in based on zero-inflated count regression models using bayesian approach...

In order to study the effect of zero-valent iron nanoparticles on morphological and physiological traits of canola (Brassica napus L. cv. 'Hayola 401') under salinity stress, a research was conducted under controlled conditions in factorial based on completely randomized design in three replicates. In the first phase, the zero-valent iron nanoparticles were synthesized and in the second phase, ...
