Extraction of Building Roof Boundaries From LiDAR Data Using an Adaptive Alpha-Shape Algorithm
(Ieee-inst Electrical Electronics Engineers Inc, 2019-08-01)
The alpha-shape algorithm was developed to extract object shapes in 2-D space; however, the accuracy of the result depends on an appropriate choice of the parameter alpha. This parameter is directly related to point density ...
Densidade de árvores por diâmetro na Floresta Estacional Decidual no Rio do Grande Sul
(Universidade Federal de Santa MariaBRRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia Florestal, 2011-02-28)
The objective of the work was to study the relationship between the density of trees
per hectare and the average diameter to a Deciduous Forest, as well as adjust the
model to describe this behavior Reineke. The study ...
The utility of open-access biodiversity information in representing anurans in the Brazilian Atlantic Forest and Cerrado
(2014-01-01)
Many geographic coordinates of species are only available in biological collections, and sometimes it is difficult to access these data. However, recent initiatives promise to compile and organize such biodiversity data ...
Analysis of conflict points between pedestrians at BRT stations to prevent the spread of respiratory diseases
(Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
Bus Rapid Transit (BRT) is a bus-based public transport system that increase the effectiveness of public transportation through dedicated lanes with busways and independent stations. However, the low capacity at the stations ...
Building boundary extraction from LiDAR data using a local estimated parameter for alpha shape algorithm
(2018-09-20)
The α-shape algorithm is a very common option to extract building boundaries from LiDAR data. This algorithm is normally executed in 2D space considering a parameter α as a binary classifier which controls the distinctiveness ...
Digital signal processing of acoustic emission signals using power spectral density and counts statistic applied to single-point dressing operation
(Inst Engineering Technology-iet, 2017-08-01)
Dressing is an important operation for the grinding process. Its goal is to recondition the wheel tool to re-establish its cutting characteristics, owing to the wear produced after successive passes. Monitoring systems ...
SPATIAL VARIABILITY AND SAMPLING DENSITY OF MAGNETIC SUSCEPTIBILITY AND SOIL PROPERTIES IN ULTISOLS OF THE MANICORE REGION, AM, BRAZIL
(Soc Brasileira De Ciencia Do Solo, 2015-05-01)
The difficulty in finding recent information on the spatial behavior of properties of soils in the Brazilian Amazon region has been a concern of many researchers. Due to the great difficulty and costs in assessing soil ...
Domain-averaged Fermi hole and domain-restricted reduced density matrices: A critical comparison
(John Wiley & Sons Inc, 2011-03)
The knowledge of the properties and the applicability of domain-restricted matrices has provided important advances in the description of molecular electronic distributions. In this work, we perform a critical comparison ...
Influence of bisphosphonates on alveolar bone density: a histomorphometric analysis
(Sociedade Brasileira de Pesquisa Odontológica, 2010)
This study is a histomorphometrical analysis of the influence of the bisphosphonate alendronate on alveolar bone density. Eighteen male Wistar rats were randomly assigned to a control group (n = 9) that received no medication ...
