Bioconvection Darcy–Forchheimer Flow of Ree‐Eyring Nanofluid Over a Riga Plate With Arrhenius Activation Energy and Viscous Dissipation

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This work examines the intricate interactions of heat radiation, viscous dissipation, the Cattaneo–Christov thermal model, gyrotactic microorganisms, Arrhenius activation energy, and Darcy–Forchheimer flow affecting Ree‐Eyring nanofluid behavior across a Riga plate.

‘It's all very well having a diverse curriculum, but if there is no curriculum, it can be as diverse as you like’: Precarity and decolonising in the neoliberal UK higher education system

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Drawing upon interview research across two academic departments as part of the early stages of a ‘decolonise the curriculum’ initiative at a Southern UK university, this study highlights a growing gulf between policy and practice in efforts to address systemic racial inequalities in UK universities. A reliance upon precarious labour, a culture

The regularization of spectral methods for hyperbolic Volterra integrodifferential equations with fractional power elliptic operator

open access: yesNonlinear Engineering, 2023
In this study, a numerical approach is presented to solve the linear and nonlinear hyperbolic Volterra integrodifferential equations (HVIDEs). The regularization of a Legendre-collocation spectral method is applied for solving HVIDE of the second kind ...

Numerical Solution of Advection–Diffusion Equation of Fractional Order Using Chebyshev Collocation Method

open access: yesFractal and Fractional, 2023
This work presents a highly accurate method for the numerical solution of the advection–diffusion equation of fractional order. In our proposed method, we apply the Laplace transform to handle the time-fractional derivative and utilize the Chebyshev ...

Preconditioning rectangular spectral collocation

open access: yes, 2015
Rectangular spectral collocation (RSC) methods have recently been proposed to solve linear and nonlinear differential equations with general boundary conditions and/or other constraints. The involved linear systems in RSC become extremely ill-conditioned as the number of collocation points increases.

The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

open access: yesBiological Reviews, EarlyView.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Domain decomposition preconditioners for the spectral collocation method [PDF]

open access: yesJournal of Scientific Computing, 1988
This paper proposes and analyzes several block iteration preconditioners for the solutions of elliptic problems by spectral collocation methods in a region partitioned into several rectangles. One considers a spectral collocation approximation which consists of collocating differential equations at Gaussian collocation points; and then a variational ...
