In this paper, a general propagation equation of ultrashort pulses in an arbitrary dispersive nonlinear medium derived in [9] has been used for the case of Kerr media. This equation which is called Generalized Nonlinear Schroedinger Equation usually... see more

We demonstrate the interest of expanded beam microlenses (around 55 µm of mode field diameter) to relax positioning tolerances and to decrease reflectance in single mode fiber to fiber interconnexions. We also point out the interest of micro-lenses ... see more

A precise calculation of the effective emissivity of isothermal diffuse cylindrical-inner-cone cavities is presented using the polynomial interpolation technique. Particularly, results are obtained for the effective emissivity of conical bases of the isot... see more

It has been shown that exposure to radiation of LED sources of light with an emission band maximum at about 465 and 520 nm having substantially identical damaging effects on animal cells in culture, that are in a logarithmic growth phase and preincubated ... see more

In this paper, thermal conductivity of ethylene glycol based copper nanoparticle decorated graphene (Cu/Gr) nanofluids are successfully synthesized by a chemical reduction tecnique using ascorbic acid antioxidant agent. Nano-sized copper nanoparticles is ... see more

Ni-substitution spinel LiNixMn2-xO4 (x = 0, 0.1, 0.2) materials were synthesized by the sol--gel method. The structure and morphology of the samples were characterized by the X-ray diffraction (XRD) and the scanning electron microscopy. T... see more

Randal-Sundrum models have an interesting feature that an effective physical scale can be generated from a much larger one of the underlying theory. In this paper, we investigate a model of supersymmetry in the Randall-Sundrum spacetime with a low cutoff ... see more

The study of variation of the size, armchair and zigzag types effects on the melting process of graphene nanoribbon. A numerical thermodynamical model has been devoted for the study. The phase transition has first order behaviour. The formation of d... see more
