Radiative MHD thin film flow of Williamson fluid over an unsteady permeable stretching sheet

Heliyon, 2018
In this research work we have examined the flow of Williamson liquid film fluid with heat transmission and having the impact of thermal radiation embedded in a permeable medium over a time dependent stretching surface.

Kumaraswamy log-logistic Weibull distribution: model, theory and application to lifetime and survival data

Heliyon, 2019
We develop the new Kumaraswamy Log-Logistic Weibull (KLLoGW) distribution by combining the Kumaraswamy and Log-logistic Weibull distributions. This new model is flexible for modelling lifetime data. Some statistical properties including quantile function,

Exploring the multifaceted roles of mathematics learning in predicting students' computational thinking competency

International Journal of STEM Education, 2023
Background There exist shared competencies between computational thinking (CT) and mathematics, and these two domains also mutually benefit from various teaching approaches. However, the linkages between mathematics and computational thinking lack robust

Effect of the projector augmented wave potentials on the simulation of thermodynamic properties of vanadium

Matter and Radiation at Extremes, 2021
We report significant differences in high-pressure properties of vanadium at zero temperature and finite temperature when different projector augmented wave (PAW) potentials are used in simulations based on density functional theory. When a PAW potential

Habituation as optimal filtering

iScience
Summary: Habituation, the reduction of responding to repetitive stimuli, is often conceptualized as a kind of attentional filter, amplifying salient signals at the expense of non-salient signals.

Solutions of nonlinear real world problems by a new analytical technique

Heliyon, 2018
Here a new analytical scheme is presented to solve nonlinear boundary value problems (BVPs) of higher order occurring in nonlinear phenomena. This method is called second alternative of Optimal Homotopy Asymptotic Method.

Predictive Modelling of Protest Event Signatures: Analyzing Temporal Dynamics and Digital Activism Discourse Across Global Movements

Journal of Social Computing
This research introduced a predictive modeling framework to analyze the temporal dynamics of social media discourse during three global movements: the Mahsa Amini Protests (2022), South African Unrest (2021), and the Black Lives Matter Movement (2020 ...

Numerical investigation of bubbles coalescence in a shear flow with diffuse-interface model

Heliyon, 2018
In this article, we apply the diffuse-interface model [developed by Shah and Yuan (2011) [21]] for collision and coalescence of two bubbles in a linear shear flow.

Linear analysis of Atwood number effects on shear instability in the elastic–plastic solids

Scientific Reports, 2021
The evolution of shear instability between elastic–plastic solid and ideal fluid which is concerned in oblique impact is studied by developing an approximate linear theoretical model.
