Weighted Overlay, Fuzzy Logic and Neural Networks for Estimating Vegetation Vulnerability within the Ecological Economical Zoning of Minas Gerais, Brazil

چکیده
This paper describes the research carried out within the framework of the Ecological Economical Zoning of Minas Gerais (ZEE-MG) to model vegetation vulnerability derived by a number of spatial inference methods. Methods based on weighted overlay, fuzzy logic, and neural networks were compared in terms of visual similarity between maps, the degree of restrictiveness concerning vulnerability, and the easiness of implementation. It was concluded that weighted overlay is the best approach to be used within the ZEE-MG. Resumo. Este artigo descreve os estudos realizados durante os trabalhos do Zoneamento Ecológico Econômico de Minas Gerais para modelar a vulnerabilidade da vegetação derivada de vários métodos de inferência espacial. Métodos baseados em sobreposição ponderada, lógica fuzzy e redes neurais foram comparados em função da similaridade visual entre os mapas, do grau de restrição em relação à vulnerabilidade e da facilidade de operacionalização. Foi concluído que o método de sobreposição ponderada é a melhor alternativa para ser usada no ZEE-MG.

Pathogenesis of odontogenic tumors is not well known. It is important to identify genetic deregulations and molecular alterations. This study aimed to investigate, through bioinformatic analysis, the possible genes involved in the pathogenesis of ameloblastoma (AM) and keratocystic odontogenic tumor (KCOT). Genes involved in the pathogenesis of AM and KCOT were identified in GeneCards. Gene lis...
