Mensuration of tree growth habits is of considerable importance for understanding forest ecosystem processes and forest biophysical responses to climate changes. However, the complexity of tree crown morphology that is typically formed after many years of growth tends to render it a non-trivial task, even for the state-of-the-art 3D forest mapping technology-light detection and ranging (LiDAR)....

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 ...

The tree shape robot is mainly applied at the exhibition or performance. In order to take the eyes of the spectator, the moving function, reproducing the fast growth process of tree, is important function of the tree shape robot. This paper proposed the mechanism to reproduce growth process of tree shape robot which is used at the exhibition or performance. Proposed mechanism for growth process...

In this research to show how 14 variables affect inflation in period 1974-2007, Bayesian model averaging and weighted average least square methods has been used. And also by using Vselect program optimal model for every independent variable has been identified. Results show that price index growth of imported goods is the main factor for inflation in Iran economic. In ranking this 14 factors –t...
