Individual Tree Diameter, Height, and Volume Functions for Longleaf Pine
Currently, little information is available to estimate individual tree attributes for longleaf pine (Pinus palustris Mill.), an important tree species of the southeastern United States. The majority of available models are local, relying on stem diameter outside bark at breast height (dbh, cm) and not including stand-level parameters. We developed a set of individual tree equations to predict t...
متن کاملAssessing model performance in forecasting long-term individual tree diameter versus basal area increment for the primary Acadian tree species
Tree basal area (ba) or diameter at breast height (dbh) are universally used to represent tree secondary growth in individual tree based growth models. However, the long-term implications of using either ba or dbh for predictions are rarely fully assessed. In this analysis, Dba and Ddbh increment equations were fit to identical datasets gathered from six conifer and four hardwood species grown ...
متن کاملEvaluation of alternative approaches for the synthesis of macrocyclic bisindolylmaleimides.
Approaches for the synthesis of macrocyclic bisindolylmaleimides, in which the indole nitrogens are linked with a tether, are described. Two alternative approaches were investigated: macrocyclisation in either the 'southern' (by adding the tether to the bisindolylmaleimide ring system) or the 'northern' district. With two-, three- and four-atom tethers, both of these approaches were unsuccessfu...
متن کاملEvaluation of Alternative Data Speculation Approaches for Superscalar Processors
Data dependences are one of the main limits to the amount of ILP that current processors can exploit. Data speculation are becoming a promising mechanism to avoid the ordering imposed by data dependences. This work presents two different approaches for improving the performance of current superscalar processors through data speculation. First, the impact of data speculation is studied for an id...
متن کاملAlternative approaches to evaluation in empirical microeconomics
This paper reviews a range of the most popular policy evaluation methods in empirical microeconomics: social experiments, natural experiments, matching methods, instrumental variables, discontinuity design and control functions. It discusses the identification of both the traditionally used average parameters and the more demanding distributional parameters. In each case, the necessary assumpti...
