Modelling railway track geometry deterioration

open access: yesProceedings of the Institution of Civil Engineers - Transport, 2011
Understanding track geometry deterioration decisively influences the planning and optimisation of track maintenance and renewal works and consequently the substantial related costs (savings) each year of every railway. To understand this deterioration it must be accurately modelled, paving the way towards its forecasting into the future.

Geometry Issues of a Gaze Tracking System

2007
One of the most confusing aspects that one meets as he introduces himself into gaze tracking is the variety, in terms of hardware equipment, of available systems providing solutions to the same matter, i.e. determining subject's gaze. Calibration permits adjusting trackers based on different hardware and image features to the subject.

Wiki Interaction Tracks in Geometry Learning

International Journal of E-Adoption, 2010
The constant comparative method (Lincoln & Guba, 1985) was used to analyze preservice teachers’ discussions and interactions in wiki discussion sections regarding geometric lessons that were written by other preservice teachers in the year before. The data was compared for the following interaction aspects of knowledge building: dialogical actions,
