Multiwave and interaction solutions and Lie symmetry analysis to a new (2 + 1)-dimensional Sakovich equation

open access: yesAlexandria Engineering Journal, 2020
In this study, we construct multi wave solutions for the (2 + 1)-dimensional Sakovich equation by utilizing the logarithmic transformation of the dependent variables and symbolic computation with the ansatz function technique.

Generalized multi-channel scheme for secure image encryption

open access: yesScientific Reports, 2021
The ability of metamaterials to manipulate optical waves in both the spatial and spectral domains has provided new opportunities for image encoding. Combined with the recent advances in hyperspectral imaging, this suggests exciting new possibilities for ...

Analytic Combinatorics of the Mabinogion Urn [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
The Mabinogion urn is a simple model of the spread of influences amongst versatile populations. It corresponds to a non-standard urn with balls of two colours: each time a ball is drawn, it causes a ball of the other kind to switch its colour.

Digital in-line holography assessment for general phase and opaque particle [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2014
We propose using the circle polynomials to describe a particle’s transmission function in a digital holography setup. This allows both opaque and phase particles to be determined.

Punk rock as popular theatre [PDF]

open access: yes, 2007
Punk rock performance consciously draws on popular theatre forms like music hall and stand-up comedy, as exemplified by the occasion when Max Wall appeared with Ian Dury at the Hammersmith Odeon.

The unit ratio-extended Weibull family and the dropout rate in Brazilian undergraduate courses.

open access: yesPLoS ONE, 2023
We propose a new family of distributions, so-called the unit ratio-extended Weibull family ([Formula: see text]). It is derived from ratio transformation in an extended Weibull random variable.

Mathematical Parameters Calculation of Double Exponential Function by a New Numerical Method

open access: yesRecent Advances in Electrical & Electronic Engineering (Formerly Recent Patents on Electrical & Electronic Engineering), 2021
Lightning electromagnetic pulse (LEMP) and high-altitude electromagnetic pulse (HEMP) are widely described by three physical parameters (rise time tr, full-width at half-maximum pulse width tw, and maximum electric field strength E0).
