Thin plate smoothing splines incorporating varying degrees of topographic dependence were used to interpolate 100 daily rainfall values, with the degree of data smoothing determined by minimizing the generalised cross validation. Analyses were performed on the square roots of the rainfall values. Model calibration was made difficult by short range correlation and the small size of the data set....

In the present article, functions with parabolic fixed points are examined and Julia sets have been investigated, including rotational symmetry revealing. Collections of which lines rays as sets, adduced. Construction algorithms for some a number results obtained by analytical investigations visualised means computer programs, described. Comparison holomorphic dynamics collection point, attract...

A permutation with no fixed points is called a derangement.The subset $mathcal{D}$ of a permutation group is derangement if all elements of $mathcal{D}$ are derangement.Let $G$ be a permutation group, a derangementgraph is one with vertex set $G$ and derangement set $mathcal{D}$ as connecting set. In this paper, we determine the spectrum of derangement graphs of order a product of three primes.
