“…Similar results were found by Marques et al (2016) where, when developing a Fuzzy model to predict values of BGHI and RTL in an environment destined to confinement of quails, in the Brazilian semi-arid region, they verified R² values equal to 0.97 and 0.98, respectively. These authors also adopted, for the output variables (BGHI and RLT), intervals represented by triangulated pertinence curves, used by several authors (Ponciano et al, 2012).…”

This study aimed to analyze bioclimatic indexes: black globe temperature and humidity index (BGHI) and radiant thermal load (RTL) in Santa Inês sheep farms, with and without coverage to develop a fuzzy logical computational model to forecast variables analyzed experimentally. Ten Santa Inês sheep were placed in two cover paddocks, and one without cover. Data recorded were: air temperature schedules and black globe (°C), relative humidity (%) and wind speed (m s -1 ), and BGHI and RTL were calculated. Computational models were developed using fuzzy logic which had as input variables, air temperature (°C) relative humidity (%) for the output variables BGHI and RTL. Based on the experimental data, there were also certain relevance curves that conform more to the results for the model generation via Fuzzy logic. The Mandani inference method was used for the preparation of rules and defuzzification of the center of gravity method was applied. The results showed that in the critical periods, 12 to 14 h, coverage was insufficient to differentiate between stress environments. It was also found that the Fuzzy models compared with the experimental data were highly correlated with R² equal to 0.99, proving it is suitable for implementation in practice.

“…Fuzzy logic has been used in many areas of knowledge to assign linear and nonlinear effects of processes to the observer's acquired experience (Marques et al, 2016). He & Dong (2018) using fuzzy and neural networks obtained good predictive performance in the interaction between robot and environment.…”

Fuzzy logic can simulate wheat yield by nitrogen and temperature nonlinearity, validating the use of hydrogel biopolymer. The objective of this study is to adapt the fuzzy logic model to the simulation of nitrogen biomass and wheat grain yield and non-linearity of the maximum air temperature, under the conditions of use of the hydrogel biopolymer, in high and low N-residual release systems. The study was conducted in 2014 and 2015, in Augusto Pestana, RS, Brazil (28 ° 26 ‘30’ latitude S and 54 ° 0 ‘58’ longitude W). The experimental design was a randomized block design with four replications in 5 x 5 factorial, for hydrogel doses (0, 30, 60, 90 and 120 kg ha-1), added in the furrow next to the seed, and N-fertilizer doses. (0, 30, 60, 90 and 120 kg ha-1), applied at the phenological stage V3 (third expanded leaf) as top-dressing, respectively. The pertinence functions together with the quantitative and linguistic values for the input and output variables are suitable for the use of fuzzy logic in the wheat yield simulation. The fuzzy model made it possible to estimate the values of biomass and wheat grain yield by nitrogen and non-linearity of the maximum air temperature under the conditions of use of the hydrogel biopolymer in high and low N-residual release systems.

RESUMO: Tendo em vista a importância do conforto térmico na avicultura de postura no Brasil, o objetivo geral destapesquisa foi avaliar o conforto térmico no galpão (pinteiro), localizado em uma granja comercial no município de Cuité (PB). A avaliação foi realizada com base nos dados de Índice da Temperatura do Globo Negro e Umidade (ITGU), avaliando o desempenho das pintainhas relacionado ao ganho de peso e as coletas de dados foram realizadas diariamente.Foi utilizado um galpão destinado para a fase de cria para aves da linhagem Lohmann LSL no período da terceira semana para desenvolvimento das aves, avaliando os valores de ITGU e comparando àqueles indicados pela literatura. Como resultados, observamos que foi possível manter as faixas de conforto térmicas bem próximas ao recomendado, e o ganho de peso mantiveram-se abaixo do indicado pelo manual da linhagem, os animais submetidos a condições térmicas adversas apresentaram menor ganho de peso. Palavras-chave: ambiência, conforto térmico, ganho de peso. THERMAL COMFORT AND POISER PERFORMANCE IN THE INITIAL PHASE (CRIA) ABSTRACT: Considering the importance of thermal comfort in poultry farming in Brazil. The aim of this research was to evaluate the thermal comfort in the shed (pestle), located in a commercial farm in the municipality of Cuité - PB. The evaluation was performed based on the data of air temperature (ºC), relative humidity of the air (%), the black globe temperature for determination of the Black Globe Temperature and Humidity Index (ITGU). Weight gain on chicks and data collection were performed daily. The shed for the breeding phase of the Lohmann LSL line was used in the third week for bird development, evaluating the ITGU values and comparing to those indicated in the literature, we observed that it was possible to keep the thermal comfort bands very close to the recommended one, and the weight gain remained distant to that indicated by the lineage manual, the animals submitted to adverse thermal conditions showed less weight gain. Keywords: ambience, thermal comfort, weight gain.
