The intense and extreme rains in southeastern Brazil are spatially temporally dynamic, corroborating their substantial complexity regarding understanding associations. Therefore, the present study aimed at determining threshold values for events of rainfall region São Carlos/SP using a climatic index, as well temporal spatial observations. RClimdex script, Rnn detection outliers were employed order to mark establish thresholds region. Values 10 mm 20 rain considered typical greater...

O aspecto dinâmico da atmosfera promove, por meio das chuvas, significativa heterogeneidade temporal e espacial nos dados pluviométricos. A orografia, como elemento de destaque nesse processo, pode intensificar tal dinâmica. Compreender a influência desse mecanismo espaçotemporal se faz necessário. Para tanto, foram analisados 31 postos pluviométricos diários na região centro-leste do Estado São Paulo, fim identificar essa influência, série histórica 1979-2017. Utilizou-se cálculo índices...

Abstract Nitrogen (N) inputs are recognised to maximise herbage mass (HM) in tropical perennial grasses, whereas less is clear on their impact HM distribution and the effects leaf (LM) area index (LAI) upper stratum. This 2 year study, carried out Pirassununga, Brazil, assessed (>20 cm) lower (<20 strata Urochloa hybrid ‘Mavuno’ grass maintained under similar pre‐ post‐cutting canopy heights with contrasting N fertilisation rates applied after each cutting (no‐nitrogen, 15, 30, 45 kg...

A produção agrícola é influenciada direta e recorrentemente pela sazonalidade dos climas. Dentre os cultivos agrícolas influenciados por esse tipo de conjuntura, destaca-se, no Brasil, a cana-de-açúcar cultivada em terras paulistas, pois, as características genéticas do clima Tropical, manifestam estações sazonais distintas, com base na variabilidade da precipitação temperatura. O presente estudo ocupou-se análise efeitos climáticos microrregião São Carlos. Para tanto, foram selecionadas...

Computer vision systems based on digital image processing have been proposed as alternative tools to traditional methods estimate leaf area, replacing the most time-consuming steps and laboring manual measurements.However, many of available applications are still determination dimensions or require excessive laborious user interventions before providing results.USPLeaf was designed process images containing single multiple leaves, automatically determine area without intervention.The...

The main aims of this paper were to study and demonstrate the benefits plant systems can provide indoors in a critical heat day.This proposed an experimental method try understand thermal response four different systems: prototype called control (no vegetation) three with combinations vegetation (green roofs green facades) installed tropical climate region.The experiments developed test cells dimensions 2.0 m × 2.50 2.71 m.Measurements internal surface temperatures air collected use specific...

Rainfall expresses one of the most complex climate factors in Southeastern Brazil. Understanding dynamics and temporal trends rainfall represents a significant challenge due to regional even global mechanisms, such as FS (Frontal Systems) SACZ (South Atlantic Convergence Zone), interaction with Pacific Oceans. The present study aimed at analyzing pluviometric tendencies S&#227o Carlos/SP, countryside Paulo State. Laplace trend test was used comprehend evolution daily region historical series...

This study is based on the principle that vegetation indexes (VIs), derived from RGB color model obtainedfrom digital images, can be used to characterize spectral signatures and classify Brachiaria brizantha cv. Xaraés according tonitrogen status (N). From colorimetric data obtained leaf blade images acquired in fi eld, three artifi cial neural networks wereevaluated performance classifi cation of N status: Feedforward Backpropagation (FFBP), Cascade ForwardBackpropagation (CFBP) Radial Base...

The article aims to present a methodology determine the positioning of pigs in stall or barn, using value receiver signal strength indicator (RSSI), measured between mobile device carried by pig and three fixed devices. RSSI data were processed neural network artificial multilayer perceptron (PMC), responsible for interpreting signals correlate them with Cartesian coordinates X Y location pig. An experiment was conducted collect at Faculty Animal Science Food Engineering (FZEA / USP) an area...

O desenvolvimento de tecnologias vem trazendo para a agricultura um progresso mudanças eficazes dentro da produção, o que gera produtos e serviços com mais qualidades. Dito isso, as máquinas agrícolas são dos exemplos aplicabilidade avanços tecnológicos fornecendo aumento produtividade no campo, bem-estar do operador melhorias das operações. Em contrapartida, os índices acidentes em atividades nas propriedades rurais consideravelmente maiores outros setores, como construção civil. Para mais,...
