Detecção e Mitigação de Ataques Usando Aprendizado Supervisionado e Orquestraçã...

A virtualização de funções de rede (Network Function Virtualization - NFV) desacopla as funções de rede dos dispositivos físicos, simplificando a implantação de novos serviços. Ao contrário das middleboxes tradicionais, as Virtual Network Functions (VNFs) podem ser dinamicamente implementadas e reconfiguradas sob demanda, colocando desafios de gerenciamento rigorosos aos sistemas em rede. Selecionar VNFs de um ...

Taper functions to describe the stem profile and total bole volume for Pinus ca...

The aim of this study was to evaluate the accuracy of taper functions for estimating diameters along the stem according to diameter classes and total volume. Studied was Pinus caribaea var. hondurensis in the Triangulo Mineiro region, state of Minas Gerais. The database consisted of 200 trees measured by the method of Hohenadl with ten sections, randomly chosen based on age and diameter distribution. The ages o...

Biomass expansion factor and root-to-shoot ratio for Pinus spp. in southern Brazil

Biomass expansion factor (BEF) and root-to-shoot ratio (R) are variables for quantification of carbon in forests. These are considered as constant values in most studies. 70 sample trees were used to BEF and R, and DBH, tree height and age. Dry total biomass, carbon and CO2 equivalent were simulated by using the IPCC default values of FEB and R, corresponding average calculated from data using in this study and...

Allometric equations for estimating biomass of euterpe precatoria, the most abu...

Allometric models to estimate biomass components such as stem mass Ms, foliage mass Ml, root mass Mr and aboveground mass Ma, were developed for the palm species Euterpe precatoria Mart., which is the most abundant tree species in the Amazon. We harvested twenty palms including above- and below-ground parts in an old growth Amazonian forest in Brazil. The diameter at breast height D ranged from 3.9-12.7 cm, and...

Changes in forest structure and biomass over ten years in a lowland amazonian f...

The topographic effects on biomass and its increment were evaluated for a terra-firme forest near Manaus, Brazil. We established three plots (60 × 60 m) on a plateau and at the bottom of a valley (namely baixio), and measured stem diameter at breast height D (> 10 cm) for tree and palm species in 2002 and 2012. Small trees (10 cm > D > 5 cm) were measured in subplots (20 × 60 m) within each plot. We also estima...

Biomass expansion factor and root-to-shoot ratio for Pinus in Brazil

The Biomass Expansion Factor (BEF) and the Root-to-Shoot Ratio (R) are variables used to quantify carbon stock in forests. They are often considered as constant or species/area specific values in most studies. This study aimed at showing tree size and age dependence upon BEF and R and proposed equations to improve forest biomass and carbon stock. Data from 70 sample Pinus spp. grown in southern Brazil trees in ...

Evaluation of the structure of a forest subjected to different girdling intensi...

In the Brazilian Amazon Area there is no long-term research reporting on the forest structural response to thinning by girdling. This study was conducted in the Tropical Forestry Experimental Station of the National Institute of Amazonian Research. The objective was to evaluate the structure of an upland forest which had a reduction of basal area by annealing by different intensities. The study was conducted 28...

Pre harvesting modeling of the diametric structure in stands of Pinus spp. usin...

The objective was to study the behavior of the distribution curves diamétric of plantations Pinus spp. in the municipality of Palmas - PR. Data are from a stand of 87 ha, with 18 years of age. The probability functions Normal, Log-normal, Gamma, Beta, Johnson SB, Weibull 2P, 3P Weibull and Weber were adjusted to estimate parameters using the Method of Moments, Method of maximum likelihood and least squares meth...

Proposição de um método de tomada de decisão de outsourcing

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia Mecânica, Florianópolis, 2019.; O ambiente globalizado de alta concorrência em que as organizações estão inseridas exigem que as mesmas adotem estratégias para se manterem competitivas. Neste cenário, o outsourcing é uma das estratégias adotadas para obtenção de vantagem competitiva. Em f...
