A mechanistic approach to topsoil damage due to slip of tractor tyres
Lyesse Laloui, Andrea Battiato, Etienne Diserens
Tractor traction tyres interact with soil by a system of normal and tangential stresses along the soil-tyre contact surface. In this interaction both soil and tyre deform according to their own stress-strain relationships. Soil deformation results in the f ...
2013Impact of biofuels production on land-use change and greenhouse gas emissions
This research assesses the effect of greenhouse gas (GHG) emission constraints imposed in biofuel importing countries on the export potential of biofuel producing countries. Several countries are promoting the introduction of biofuels on their energy matri ...
EPFL2012Mathematical modelling of swirling flow in hydraulic turbines for the full operating range
We introduce and validate a novel mathematical model for computing the radial profiles of both axial and circumferential velocity components, respectively, of the swirling flow exiting the runner of hydraulic turbines within the full operating range. We as ...
Elsevier2011Wheel Torque Control in Rough Terrain - Modeling and Simulation
This paper presents a method for wheel-ground contact angle measurement and a traction control strategy minimizing slip in rough terrain. The slip minimization algorithm has been tested and compared with a standard speed control in simulation, which allows ...
2005Applying the Patuxent Landscape Unit Model to human dominated ecosystems: the case of agriculture
Non-spatial dynamics are core to landscape simulations. Unit models simulate system interactions aggregated within one space unit of resolution used within a spatial model. For unit models to be applicable to spatial simulations they have to be formulated ...
Elsevier2003Modeling of the Soil Water Balance Based on Time-Dependent Hydraulic Properties under Different Tillage Practices
A simulation model with time-dependent hydraulic conductivity parameters was used to predict the effects of three different tillage practices: conventional tillage (CT), no-tillage (NT) and subsoiling tillage (ST) on the components of the soil water balanc ...
