1. NEURO-FUZZY MODELING OF EYEBALL AND CREST TEMPERATURES IN EGG-LAYING HENS
ABSTRACT Considering the challenges faced by poultry farming, this study aimed to develop a neuro-fuzzy model to predict eyeball and crest temperatures of egg-laying hens based on environmental conditions (dry bulb temperature and relative humidity). To develop the models and simulations, Matlab’s Fuzzy Toolbox® (Anfisedit) was used. Different configurati

2. Investigation on Solar PV generation and design of switched reluctance motor for Smart Agriculture actuation system
ABSTRACT This paper presents standalone solar photovoltaic (PV) powered fed actuation system employing a switched reluctance motor (SRM) particularly used in remote and rural areas. The converter efficiency is achieved by changing ON and OFF state of solar PV drive. An electronic commutation drives SRM drive with achieved by position hall sensor and encoder.

3. Local linear model tree and Neuro-Fuzzy system for modelling and control of an experimental pH neutralization process
This paper describes the modelling and control of a pH neutralization process using a Local Linear Model Tree (LOLIMOT) and an adaptive neuro-fuzzy inference system (ANFIS). The Direct and Inverse model building using LOLIMOT and ANFIS structures is described and compared. The direct and inverse models of the pH system are identified based on experimental da

4. Desenvolvimento de modelo multidimensional de predição de peptídeos antimicrobianos utilizando um sistema de inferência neuro-fuzzy adaptativo (ANFIS)
Antimicrobial peptides (AMPs) are defense molecules widely distributed and represent a promising alternative for solving the problem of antibiotic resistance. Nevertheless, the experimental time needed to screen putative AMPs makes computational simulations based on peptide sequence analysis and/or molecular modeling extremely attractive. Artificial intellig

5. Controle preditivo baseado em modelo neuro-fuzzy de sistemas não-lineares aplicado em sistema de refrigeração = : Model predictive control based on neuro-fuzzy nonlinear systems applied to a refrigeration plant / Model predictive control based on neuro-fuzzy nonlinear systems applied to a refrigeration plant
Refrigeration systems can be found in many different branches of industry and are characterized as great energy consumers with considerable non-linear behavior. Several studies have been developed to promote the reduction of energy costs and to minimize the effects of nonlinearities in these systems. The use of automation and process control, particularly th

11. Previsão de carga de curto prazo usando ensembles de previsores selecionados e evoluidos por algoritmos geneticos / Short-term load forecasting using esembles of selected and evolved predictors by genetic algorithms
This work proposes a methodology for short-term electric power load forecasting. This methodology is being widely used under the context of time series prediction and pattern recognition. It was named "ensembles" by the authors who developed it. This name carries the meaning of an assemblage of parts considered as forming a whole. Therefore, this name expres

12. SISTEMA INTELIGENTE DE OTIMIZAÇÃO DE ALTERNATIVAS DE DESENVOLVIMENTO DE CAMPOS PETROLÍFEROS / INTELLIGENT SYSTEM FOR OPTIMIZATION OF ALTERNATIVES FOR PETROLEUM FIELDS DEVELOPMENT
This work investigates the problem of optimization of alternatives for petroleum fields` development. A development alternative refers to the way a well-known and delimited petroleum field is placed in production. This process involves the determination of the number, localization and scheduling of producer and injector wells. Thus, the optimization of alter
