A second order finite difference scheme for singularly perturbed Volterra integro-differential equation

Alexandria Engineering Journal, 2020
In this paper, a singularly perturbed Volterra integro-differential equation, characterised by a single layer, is investigated. A numerical technique which uses a non-standard finite difference scheme is implemented to solve the differential part ...

Enhancing finite difference approximations for double barrier options: mesh optimization and repeated Richardson extrapolation [PDF]

, 2021
We show that the performances of the finite difference method for double barrier option pricing can be strongly enhanced by applying both a repeated Richardson extrapolation technique and a mesh optimization procedure. In particular, first we construct a

Consumer attitudes, willingness to pay and hedonic evaluations of innovative legume gnocchi products

Journal of the Science of Food and Agriculture, Volume 105, Issue 5, Page 2867-2878, 30 March 2025.
Abstract BACKGROUND With growing concerns over the adverse effects of animal‐derived products on health, animal welfare and the environment, the rising popularity of plant‐based foods underscores the importance of understanding consumer preferences and determining acceptance.

Interplanetary frontiers: terraforming from an invasion science perspective

Oikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Zur geschichte der Richardson-extrapolation

Historia Mathematica, 1979
SummariesIn modern numerical mathematics the keywords “Richardson extrapolation” and “Romberg quadrature” have gained an essential place, and they represent typical examples of numerically efficient and trustworthy procedures. While the Romberg quadrature was regarded relatively early as a special application of the Richardson extrapolation one seldom ...

Richardson extrapolation-based sensitivity análisis in the multi-objective optimization of analog circuits [PDF]

, 2013
The feasible solutions provided by a multi-objective evolutionary algorithm (MOEA) in the optimal sizing of analog integrated circuits (ICs) can be very sensitive to process variations.

Mechanisms and impacts of future plant invasions: research agendas and management needs under disruptive social‐ecological change scenarios

Oikos, EarlyView.
No‐analogue futures are characteristic of the Anthropocene, but how global change, and societies' responses, will affect plant invasions remains unclear. Conducting research now to address future needs is crucial for guiding invasion management and policy.
