Border fertigation: field experiments and a simple model

Border Collision Bifurcations in a simple oligopoly model with constraints

In this paper, we run through an example of oligopoly, recently introduced in the literature, where firms operate under constraints. The dynamical system describing firms’ choices over time assumes the form of a piecewise-smooth map because of such constraints. By carrying on a leading example, we show possible routes to complexity in the model, mainly due to border collision and homoclinic bif...

Rapid Plateau border size variations expected in three simple experiments on 2D liquid foams.

Up to a global scaling, the geometry of foams squeezed between two solid plates (2D GG foams) essentially depends on two independent parameters: the liquid volume fraction and the degree of squeezing (bubble thickness to diameter ratio). We describe it in two main asymptotic regimes: fully dry floor tiles, where the Plateau border radius is smaller than the distance between the solid plates, an...

Interaction with a field: a simple integrable model with backreaction

The classical model of an oscillator linearly coupled to a string captures, for a low price in technique, many general features of more realistic models for describing a particle interacting with a field or an atom in an electromagnetic cavity. The scattering matrix and the asymptotic in and out-waves on the string can be computed exactly and the phenomenon of resonant scattering can be introdu...

A Study of Precision Forging of Steel Spur Gears: Upper Bound Model and Experiments

Precision forging process is widely used for the production of spur gears due to its advantages such as improved strength and surface finish, little waste of materials and reduction in the machining time of the gear. An important aspect of precision forging process is the load required to perform the process successfully and design the forging tools. In this research, a new kinematically admiss...
