1. Fuzzy Boundary for Beams Vibrations in Vehicles

ABSTRACT This work aims to study the transversal motion of a car’s chassis, modeled by a beam and supported at its ends by two sets of spring-damper elements. A finite differences method is utilized along with Robin boundary conditions to solve the mathematical modeling. The constants of the boundary conditions are modeled by a fuzzy parameter obtained thr

2. FUZZY MODELING OF THE EFFECT OF IRRIGATION DEPTHS ON BEET CULTIVARS

ABSTRACT The objective of this study was to develop a Fuzzy Rule-Based System (FRBS) for the mathematically modeling of the irrigation level effect on beet cultivars ( Beta vulgaris L.). From an agronomic experiment carried out in a protected environment (greenhouse), it was defined as input variables, for each cultivar, the irrigation levels (depths of 25,

The unstructured and unplanned implementation of technological solutions leads to wastage of resources and imposes itself as a barrier to achieving the potential benefits of information technologies and communication. The problem increases when managers who operate these technologies are part of the public administration, as structural issues make this scena

5. Evolving granular systems = : Sistemas granulares evolutivos / Sistemas granulares evolutivos

In recent years there has been increasing interest in computational modeling approaches to deal with real-world data streams. Methods and algorithms have been proposed to uncover meaningful knowledge from very large (often unbounded) data sets in principle with no apparent value. This thesis introduces a framework for evolving granular modeling of uncertain

6. Classification of the severity of diabetic neuropathy: a new approach taking uncertainties into account using fuzzy logic

OBJECTIVE: This study proposes a new approach that considers uncertainty in predicting and quantifying the presence and severity of diabetic peripheral neuropathy. METHODS: A rule-based fuzzy expert system was designed by four experts in diabetic neuropathy. The model variables were used to classify neuropathy in diabetic patients, defining it as mild, moder

7. Avaliação econômica de sistemas extensivos de cria no Pantanal utilizando a teoria dos conjuntos Fuzzy ? processo de validação.

A sustentabilidade dos biomas é alicerçada no tripé ambiental, social e econômico. Para a manutenção do equilíbrio destes três aspectos no Pantanal é importante estabelecer política diferenciada, que auxilie aos produtores a manterem o Pantanal produtivo e conservado. A definição de indicadores de sustentabilidade de sistema de produção pecuár

A Fuzzy rule-based system is a mathematical tool that uses the fuzzy logic to find answers or control a specific type of problem. We will use this tool to classify people as the ability to entrepreneurship, in order to qualify them as suitable or not to open their own company. Furthermore, we show two more applications of this tool: one related to medical di

Fuzzy sets are used in the representation of vague and imprecise knowledge. Neural networks, besides their computational parallelism, also have learning capabilities. The combination of such both paradigms is an attempt to congregate their benefits in an integrated system, such a fuzzy neural network. T-norms are functions that actuate like intersection and
