Tree-growth

Tree Growth Visualization

In computer graphics, models describing the fractal branching structure of trees typically exploit the modularity of tree structures. The models are based on local production rules, which are applied iteratively and simultaneously to create a complex branching system. The objective is to generate three-dimensional scenes of often many realisticlooking and non-identical trees. Our goal, instead,...

Temperature and tree growth.

Tree growth helps US forests take up 12% of the fossil fuels emitted in the USA (Woodbury et al. 2007), so predicting tree growth for future climates matters. Predicting future climates themselves is uncertain, but climate scientists probably have the most confidence in predictions for temperature. Temperatures are projected to rise by 0.2 °C in the next two decades, then by 1.5–3.5 °C at the e...

Regenerative tree growth processes

We introduce regenerative tree growth processes as consistent families of random trees with n labelled leaves, n ≥ 1, with a regenerative property at branch points. We establish necessary and sufficient conditions on the growth rules under which we can apply results by Haas and Miermont to establish self-similar random trees and residual mass processes as scaling limits. This framework includes...

Dialogue as Collaborative Tree Growth

This paper applies Dynamic Syntax (Kempson et al., 2001) to dialogue modelling, and provides a characterisation of production that is relative to a converse process of tree growth which constitutes a parse check. As evidence for this approach, we place it in a psycho-linguistic perspective, using it to model (i) the parsing/production of elliptical expressions, (ii) dialogue properties such as ...
