in this research, a two-phase algorithm based on the artificial neural network (ann) and a harmony search (hs) algorithm has been developed with the aim of assessing the reliability of structures with implicit limit state functions. the proposed method involves the generation of datasets to be used specifically for training by finite element analysis, to establish an ann model using a proven an...

We determine the ultimate potential of quantum imaging for boosting the resolution of a far-field, diffraction-limited, linear imaging device within the paraxial approximation. First, we show that the problem of estimating the separation between two pointlike sources is equivalent to the estimation of the loss parameters of two lossy bosonic channels, i.e., the transmissivities of two beam spli...

We investigate three types of amplification processes for light fields coupling to an atom near the end a one-dimensional semi-infinite waveguide. consider two setups where drive creates population inversion in bare or dressed basis three-level and one setup is due higher-order driven two-level atom. In all cases, waveguide acts as mirror light. find that this enhances ways compared same open F...
