streamflow recession indicates the river network balance between revenue and losses of river. recession curve expreses the storage- output relationship for the catchment. the aim of this study was trend anaylysis, modeling of streamflow recession and uncertainty estimation in shahmokhtar station on the bashar river in kohgiluyeh and boyer ahmad province. based on the results of the mann-kendall...

We prove an ultrametric q-difference version of the MailletMalgrange theorem on the Gevrey nature of formal solutions of nonlinear analytic q-difference equations. Since degq and ordq define two valuations on C(q), we obtain, in particular, a result on the growth of the degree in q and the order at q of formal solutions of nonlinear q-difference equations, when q is a parameter. We illustrate t...

Since at least Engle (1982) and Stock and Watson (2002), we know that the conditional variance of future output and inflation evolves over time. However, in these seminal contributions, the risk of real activity and inflation is implicitly considered as symmetric. In this paper, we investigate the time evolution of the conditional distribution of macroeconomics variables with a special interest...

We use the Schmidt Subspace Theorem to establish the transcendence of a class of quasi-periodic continued fractions. This improves earlier works of Maillet and of A. Baker. We also improve an old result of Davenport and Roth on the rate of increase of the denominators of the convergents to any real algebraic number.

Self-Organizing Maps aims ideally to group homogeneous individuals, highlighting a neighbourhood structure between classes in a chosen network. Recent approaches propose to exploit the homogeneity of the underlying classes for data completion purposes (see [2]). The aim of this paper is two-fold. First, we present and slightly modified two complementary approaches in completing the stochastic m...
