A remotely pumped Erbium-doped system for the amplification of an optical signal long-reach (LR) next-generation passive networks (NG-PONs) is presented in this paper. The will be deployed with/over current point to multi-point technology with/without backward compatibility. Remote pumping allows extending reach distribution and magnification splitting ratio as well, which most important increa...

In this work, we present Point Transformer, a deep neural network that operates directly on unordered and unstructured point sets. We design Transformer to extract local global features relate both representations by introducing the local-global attention mechanism, which aims capture spatial relations shape information. For purpose, propose SortNet, as part of induces input permutation invaria...

in this paper, two sets of sufficient conditions are obtained to ensure the existence and stability of a unique equilibrium point of unforced first-order fuzzy relational dynamical systems by using two different approaches which are both based on the fuzzy relational matrix of the model.in the first approach, the equilibrium point of the system is one of the centers of the related membership fu...

we de ne approximate xed point in fuzzy norm spaces and prove the existence theorems, we also consider approximate pair constructive map- ping and show its relation with approximate fuzzy xed point.

in this work, by employing the krasnosel'skii fixed point theorem, we study the existence of positive solutions of a three-point boundary value problem for the following fourth-order differential equation begin{eqnarray*} left { begin{array}{ll} u^{(4)}(t) -f(t,u(t),u^{prime prime }(t))=0 hspace{1cm} 0 leq t leq 1, & u(0) = u(1)=0, hspace{1cm} alpha u^{prime prime }(0) - beta u^{prime prime...
