15 صفحه اولModel-Fitting Approach to Kinetic Analysis of Non-Isothermal Oxidation of Molybdenite
The kinetics of molybdenite oxidation was studied by non-isothermal TGA-DTA with heating rate 5 ºC.min-1.The model-fitting kinetic approach applied to TGA data .The Coats-Redfern method used for model fitting. The popular model-fitting gives excellent fit for non-isothermal data in chemically controlled regime. The apparent activation energy was determined to be about 34.2 kcalmo...
متن کاملComparing Knowledge Tracing and Performance Factor Analysis by Using Multiple Model Fitting
Student modeling is very important for ITS due to its ability to make inferences about latent student attributes. Although knowledge tracing (KT) is a well-established technique, the approach used to fit the model is still a major issue as different model-fitting approaches lead to different parameter estimates. Performance Factor Analysis, a competing approach, predicts student performance bas...

متن کاملModel Fitting and Model Evidence for Multiscale Image Texture Analysis
This paper, begins with an overview of the two levels of Bayesian inference: model fitting and model selection, and shows how they can be used for the image texture analysis. The applied models are the Gauss-Markov and Gibbs auto-binomial Random Fields. In the second part the article introduces a linear model for the image wavelet coefficients able to explain the full description of the spatial...
