Modelling the evolution of human trail systems
Article Abstract:
A model of pedestrian motion is developed to examine the evolution of trails in urban green spaces, using an active walker model that considers pedestrian motion and orientation. The aim was to determine the topological structures of such trail systems and whether optimal path systems could be predicted for urban planning. The model would be of use to urban planners and landscape gardeners when developing comfortable and convenient way systems.

Palaeoaltimetry from energy conservation principles
Article Abstract:
A new alternative paleobotanical method is developed to study the past changes in the average elevations of large continental areas. The method is based on energy conservation in the atmosphere, where the enthalpy is determined instead of the temperature. The influences exerted by the paleoclimate does not affect the results of paleoelevation obtained by this method.

Increased sedimentation rates and grain sizes 2-4 Myr ago due to the influence of climate change on erosion rates
Article Abstract:
Research is presented concerning the increases in sedimentation rates which are occurring globally in inactive and active mountain belts. The influence of climatic changes on the rate of global erosion is discussed.
