The purpose of this article is to assist Brazilian authorities in directing resources reduce the rate intentional homicide per 100,000 inhabitants federative units Brazil. In sense, linked information made available by National Secretariat for Public Security (Senasp), it was decided apply grouping technique known as k-means group FU’s similar rates. Three clusters were found and, then, a detailed description each belonging three carried out. We noticed that only form cluster 1 have below 16...

ABSTRACT: Assessing sugarcane (Saccharum spp.) stalk growth helps to adequately manage the phenological stages of crop. The aim this study was describe height-growth curve four varieties (RB92579, RB93509, RB931530 and SP79-1011), in irrigated plant-cane ratoon cane plantations, using Logistic Gompertz nonlinear models, while considering all deviations from assumptions. model parameters were estimated based on least squares method Gauss-Newton algorithm. To select most suitable model,...

Abstract: The objective of this work was to evaluate how the parameterization and application different allometric values affect obtention most adequate fit von Bertalanffy’s model, in description growth curve meat-producing mammals (bovine, pigs, rabbits, sheep). Among nonlinear models, has been very often applied several areas, with parameterizations. This model commonly used an value m = 2/3; however, for mammals, it is believed that can be 3/4. analyzed data referring mass according...

Methods 22 male players were evaluated countermovement jump, 10-m sprint, creatine kinase, total quality (TQR), Brunel Mood Scale (fatigue vigor) before immediately 3, 24, 48 h posttraining. Hierarchical cluster analysis allocated to different using area under curve (AUC) percentage differences from baseline. One-way ANOVA compared time course each variable players’...

Pepper (Capsicum sp.) is important for the Brazilian agribusiness, serving as raw material food, pharmaceutical and cosmetic industries. The adequate evaluation of its plants growth may help in understanding causes crops yield variation, with it being able to be studied by regression models, which management different phenological phases. This study aimed compare fit linear Polynomial model Logistic Gompertz nonlinear models description pepper from Doce cultivar. Estimates were obtained...

Brazil is a major producer in the timber sector, mainly with use of wood from species genus Eucalyptus, 26.1% planted forests located Minas Gerais. Researchers and manufacturers have been searching for techniques objective making full these forests, primary focus on greater growth. A modeling growth curves an alternative estimation oral production andan important aid tool researcher's decision making. Growth are commonly studied by nonlinear regression models, which assumptions that if not...

Brazil is the world's largest sugarcane producer (Saccharum spp.), followed by India and China.In 2019, produced 642.7 million tons of sugarcane, having collected 1.44 billion 983.52 dollars from sugar ethanol exports, respectively.For crop management, it important to monitor plant growth, duration growth phases point physiological maturation.The aim this study was evaluate fit nonlinear Logistic, Gompertz, Brody von Bertalanffy models height diameter ratoon cane stalk RB92579 variety,...

It has been increasingly important to control N-fertilizers, seeking high efficiency. This study aims describe, using the von Bertalanffy model, cumulative losses of nitrogen (N) by ammonia volatilization (NH3-N) from conventional and stabilized N-fertilizers applied in coffee orchard. The experiment was performed Lavras municipality, Minas Gerais state, Brazil during 2015/2016 growing season. A randomized block design used, with seven treatments (stabilized N-fertilizers) three fertilizer...


 The growth curves of animals, in general, have an “S” shape, also known as sigmoidal curves. This type curve is well fitted by nonlinear regression models, including von Bertalanffy’s model, which has been widely applied several areas, being presented literature through different parameterizations, practice, can complicate its understanding, affect nonlinearity measures and inferences about parameters. To quantify the present a Bates Watts geometric concept curvature used. aim this...

Um surto contínuo de pneumonia associado a um novo coronavírus (COVID-19) foi relatado na cidade Wuhan China e rapidamente se espalhou para muitos países, inclusive o Brasil. Como trata uma doença muito contagiosa rápido agravamento do quadro clínico paciente, entender como deu desenvolvimento dos casos óbitos nos primeiros dias pode ajudar no planejamento medidas governamentais, até mesmo possíveis pandemias futuras. Com isso, objetivo deste trabalho é apresentar crescimento número...

Abstract The objective of this work was to study the growth curves total dry matter (TDM) accumulation P30F33 and GNZ2004 maize hybrids using nonlinear models. used models were: Brody, Gompertz, logistic, Meloun I, II, Michaelis-Menten, modified Mitscherlich, Richards, Schnute, von Bertalanffy, Weibull. To estimate parameters, least squares method Gauss-Newton convergence algorithm were used. adjusted coefficient determination, residual standard deviation, Akaike information criterion as...

A COVID-19 é uma infecção causada pelo coronavírus SARS-CoV-2, sendo que seus primeiros registros foram na cidade chinesa de Wuhan em dezembro 2019, e foi considerada pela Organização Mundial da Saúde (OMS) pandemia mundial março 2020. No Brasil, a se espalhou atingindo as 27 unidades federativas (UFs). Com isso, tomadas decisões para diminuir velocidade transmissão baseadas nas recomendações OMS, onde principal isolamento social. Entretanto, devido heterogeneidade população cada das UFs,...

ABSTRACT Rabbit farming is an activity with high growth potential due to its easy handling, prolificacy, low polluting impact, and adaptability family systems, producing meat of biological value. Therefore, the aim this work was evaluate, using von Bertalanffy's nonlinear model, curves weight as a function age in ‘Flemish Giant Rabbits’ ‘New Zealand White’ crossbred rabbits. Two different data collections were used: longitudinal method cross-sectional method. The experiment carried out at...

An accurate assessment of frost damage in coffee plantations can help develop effective agronomic practices to cope with extreme weather events. Remotely piloted aircrafts (RPA) have emerged as promising tools evaluate the impacts caused by on production. The objective was impact plants, using vegetation indices, different ages and areas climatic risks. We evaluated two located Brazil, aged one years date occurrence. Multispectral images were collected a remotely aircraft, three days after...

Nonlinear regression models are widespread in the literature, and one of their main applications is study sigmoidal growth curves. There several for this purpose, most used logistic, Gompertz, von Bertalanffy, Brody models. Each them has its own characteristics more suitable a given curve shape. criteria literature selecting appropriate model, but there no consensus on best criteria. Thus, present aims to evaluate accuracy selection via Monte Carlo simulation, considering nonlinear Four...

The COVID-19 pandemic has spread rapidly around the world in a frightening way. In Brazil, third country with highest number of infected and deaths from disease, it is important for government health authorities to identify federation units that stand out cases this disease target resources. circular scan statistic proposed by Martin Kulldorff allows some statistical significance relation Brazil. Such are known as clusters. Once these clusters were identified, we used coefficients incidence...

The dynamics of organic waste decomposition in the soil can be described by nonlinear regression models, however, theory for models is valid sufficiently large samples, and general, small these properties are unknown. One methods data analysis that has been widely used to overcome this problem bayesian inference, as it advantage being able work with addition allowing incorporation information from previous studies, even having a probability distribution parameters, consequently, present...
