The Drop Size Distributions (DSDs) measured in northern Benin (West Africa) are analyzed with (????) and ????(????) functions. The (????) function represents the number of raindrops per unit of volume and by interval of diameters, while the ????(???? [...]

In this research work, we opt for the static spherical symmetric metric. Thus, taking into account the own gravitational field of elementary particles, we have obtained exact static spheric symmetric solutions of the nonlinear spinor and gravitationa [...]
Techniques based on nonlinear partial differential equations have impacted the image processing field with increasing success supported by experimental results. In this article, we have proposed a 2-dimensional model of image processing by combining [...]

In this paper, a ferroelectric structure consisting of barium stannate titanate piezoelectric ceramic is used for mathematical modeling. The study of the dynamics of the structure requires the poling process that makes the ceramic active. This may be [...]
In this article, we study the dynamics of optical soliton (Gausson) pulses in waveguides based on ENZ-materials. The theoretical approach used is based on the handling of the non-linear Schrödinger's equation using the moment method. The physical sys [...]
We give a detailed account of an ab initio computational treatment of multiphoton single ionizationwith or without excitation as well as double ionization of two-electron atoms exposed to short-wavelength electric fields. This treatment is time d [...]
In this paper, we use time-frequency analysis for pulse propagation in a linear dispersive medium. The Gaussian and sinh-Gaussian profiles are used as input ultra-short pulses (0, ) in the time domain. E(0, ω) is the corresponding spectral profi [...]
In this work, we obtain results by using a physical potential Φ m ( x , y ) whose parameters have biological significance [5] to explain the interaction between two species in population dynamics. In using the degenerated parameters [8], this poten [...]
