The effects of growth phase, reductions in the water activity (a w) of the growth medium and mild desiccation on the composition and the degree of unsaturation of cellular fatty acids (CFA) of Sinorhizobium meliloti, Bradyrhizobium elkaniiand Bradyrhizobium japonicum were studied. During the course of growth, an interchange of cis-vaccenic with(More)
In this paper we present an estimation method for a non-minimum phase MA, AR or ARMA models. This method is based on the maximum kurtosis property. First the spectrally equivalent minimum-phase (SEMP) filter is estimated from the output statistics, then the kurtosis allows us to localise the zeros of the true transfer function from the zeros of its SEMP(More)
