Comparison of nest holes between Syrian Woodpecker (Dendrocopos syriacus) and Middle Spotted Woodpecker (Dendrocoptes medius) around Yasouj city in Southwestern of Iran. [PDF]
Iranian Journal of Animal Biosystematics, 2019 In this study, the nest-cavity characteristics of Middle Spotted and Syrian Woodpeckers as well as tree characteristics (i.e. tree diameter at breast height and hole measurements) chosen by each species were analyzed.

Developing Allometric Equations for Teak Plantations Located in the Coastal Region of Ecuador from Terrestrial Laser Scanning Data [PDF]
, 2019 Traditional studies aimed at developing allometric models to estimate dry above-ground biomass (AGB) and other tree-level variables, such as tree stem commercial volume (TSCV) or tree stem volume (TSV), usually involves cutting down the trees.

Advanced Engineering Materials, EarlyView.This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...

Height and diameter of Brownian tree [PDF]
Electronic Communications in Probability, 2015 By computations on generating functions, Szekeres proved in 1983 that the law of the diameter of a uniformly distributed rooted labelled tree with n vertices, rescaled by a factor n^{1/2} , converges to a distribution whose density is explicit. Aldous observed in 1991 that this limiting distribution is the law of the diameter of the Brownian tree.
