Abstract The use of anthocyanin as a source of naturaldyes has been increased due to itslack of toxicity. In this study, natural dyes from the mulberry fruits extracted under different operating conditions such as extraction time (2060 min), temperature (4080 0C) and mass of the mulberry (1025 g)[r]

For a double array of independent random elements {Vmn, m ≥ 1, n ≥ 1} in a real separable Banach space, conditions are provided under which the weak and strong laws of large numbers for the double sums Pm i=1 Pn j=1 Vij , m ≥ 1, n ≥ 1 are equivalent. Both the identically distributed and the nonident[r]
In this paper, we aimed at examining the nature of the impact of external debt on economic growth in 44 SubSaharan African countries using an unbalanced dataset that ranges from 1970 to 2002. Instead of using the annual data, which was subject to a serious autocorrelation problem, we calculated[r]
Chen, Fang and Shao (Ann. Probab., 2013, 262293) used Stein’s method to obtain Cram´er type moderate deviation results for bounded dependent random variables. The boundedness restriction prevents the application of their general result from computing bounds in various examples, Jack measure being on[r]
An artificial neural network (sometimes abbreviated ANN, or shortened to just neural network when the context is clear) is a software system that loosely models biological neurons and synapses. Before explaining exactly how neural networks work, it is useful to understand what types of problems they[r]

The Birkhoff’s Ergodic Theorem (BET) is one of the most important and beautiful results of probability theory. The study of ergodic theorems was started in 1931 by von Neumann and Birkhoff, having its origins in statistical mechanics. In recent decades, the BET has been considerable interest in the[r]
