Development of web-based tools for spectral data analysis and mining

The objective of this research was to build up a model (decision tree) using data mining techniques such as feature selection and data classification, for predicting broiler

A tree model that was consisted of spleen width, portal vein diameter and prothrombin time was developed by classification and regression tree analysis achieved a diagnostic accuracy

A presente dissertação, elaborada no âmbito do Mestrado em Gestão de Recursos Humanos, tem como objetivo estudar o perfil de competências-chave procurado nos voluntários, no

The main objective of this thesis is comprised by the design and development of s-WIM, a scalable data model with an algebra which allows for fast Web mining prototyping, after the

A investigação dos acontecimentos significativos na aprendizagem do violino procurava compreender melhor a perspectiva do aluno relativamente a este processo e,

Therefore, based on the best fit of the observed data to the regression model for the PP variable and yield losses per plant of yellow nutsedge of 0.45 and 0.88% (parameter i),

The parameters were estimated by mixed models, and selection was performed by the harmonic mean of the relative performance of genetic values, using three strategies: selection

Adsorption parameters for the Langmuir, Freundlich and Temkin isotherms were determined and the equilibrium data were best described by the Lang- muir isotherm model, with
