NEW HYBRID ALGORITHMS FOR ESTIMATING TREE STEM DIAMETERS AT BREAST HEIGHT USING A TWO DIMENSIONAL TERRESTRIAL LASER SCANNER

New Hybrid Algorithms for Estimating Tree Stem Diameters at Breast Height Using a Two Dimensional Terrestrial Laser Scanner

In this paper, a new algorithm to improve the accuracy of estimating diameter at breast height (DBH) for tree trunks in forest areas is proposed.First, the information is collected by a two-dimensional terrestrial laser scanner (2DTLS), which emits laser pulses to generate a point cloud.After extraction and filtration, the laser point clusters of t

Evolution of the Piscine orthoreovirus Genome Linked to Emergence of Heart and Skeletal Muscle Inflammation in Farmed Atlantic Salmon (Salmo salar)

Heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon (Salmo salar) was first diagnosed in Norway in 1999.The disease is caused by Piscine orthoreovirus-1 (PRV-1).The virus is prevalent in farmed Atlantic salmon, but not always associated with disease.Phylogeny and sequence analyses of 31 PRV-1 genomes collected over a 30-year per
