Our simulations show that planting in patches with a large distance between patches should limit the time necessary for the pest to colonise a new field although the severity of

1) Modeling the tick life cycle, taking account of temperature fluctuation and sea- sonality: In this part our objective is to model tick life cycle in order to study the effect

Coville also obtained the existence of at least one travelling-wave solution in the monostable case.. Our first theorem extends some of the afore-mentioned results of Schumacher to

In this paper, we prove existence, uniqueness and regularity for a class of stochastic partial differential equations with a fractional Laplacian driven by a space-time white noise

6 In this paper, we present different simulation studies and one case study on copper data to study the application of the SSD methodology to the EC10 for population

Such coupled room impulse responses can be synthesized using a recently proposed sound energy decay model based on a diffusion equation and adapted to coupled spaces.. This

The objectives of this paper is to provide stability con- ditions for a class of linear ordinary differential equa- tion coupled with a reaction-diffusion partial differential

Indeed, sensitivity tests showed that the maximum fish swimming speed (3 or 6 BL s −1 ) modulated the average northern limit of the population to between ∼21°N (for 3 BL s −1 )
