EVALUATION OF SITE QUALITY AND MODELLING TREE PRODUCTIVITY BY LIDAR TECHNOLOGY IN SALT-AFFECTED OAK FOREST TERRITORY [PDF]
Natural Resources and Sustainable Development, 2019 Forest site quality evaluation is an important part of forest planning and forest management. A forest site is characterized by forest biomass, which is determined by elevation characteristics, soil type and climate.

Influence of the slope of terrain on the spatial variability of the wood density within Eucalyptus trees [PDF]
, 2012 The aim of this study was to understand how contrasting environments influence the wood formation in Eucalyptus clones and the effect on wood density and spatial variability.

Vegetation height products between 60° S and 60° N from ICESat GLAS data. [PDF]
, 2012 We present new coarse resolution (0.5 ×0.5 )vegetation height and vegetation-cover fraction data sets between 60 S and 60 N for use in climate models and ecological models.

The cut‐tree of large trees with small heights [PDF]
Random Structures & Algorithms, 2017 AbstractWe destroy a finite tree of size n by cutting its edges one after the other and in uniform random order. Informally, the associated cut‐tree describes the genealogy of the connected components created by this destruction process. We provide a general criterion for the convergence of the rescaled cut‐tree in the Gromov‐Prohorov topology to an ...

Advanced Functional Materials, EarlyView.The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of

Almost sure asymptotics for the random binary search tree [PDF]
, 2010 We consider a (random permutation model) binary search tree with n nodes and give asymptotics on the loglog scale for the height H_n and saturation level h_n of the tree as n\to\infty, both almost surely and in probability.

Advanced Functional Materials, EarlyView.Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Biomass Estimation and Uncertainty Quantification From Tree Height
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 We propose a tree-level biomass estimation model approximating allometric equations by LiDAR data. Since tree crown diameter estimation is challenging from spaceborne LiDAR measurements, we develop a model to correlate tree height with biomass on the ...

Impact of pine looper defoliation in Scots pine [PDF]
, 2003 Widespread defoliation of forests caused by insects or fungi cause economic losses throughout the world. Successful outbreak management involves cost/benefit estimation and requires knowledge of potential yield losses. Currently, such knowledge is scarce.

The height of q-Binary Search Trees [PDF]
Discrete Mathematics & Theoretical Computer Science, 2002 q-binary search trees are obtained from words, equipped with a geometric distribution instead of permutations. The average and variance of the heighth computated, based on random words of length n, as well as a Gaussian limit law.
