Regression models for the mean quality-adjusted survival time are specified from hazard functions of transitions between two states and the mean quality-adjusted survival time may be a complex function of covariates. We ...

This article describes a model for the evaluation of educational quality using a virtual learning environment. This model describes quantitative and qualitative aspects that are based on a set of quality attributes and ...

This paper presents a methodology for modeling high intensity discharge lamps based on artificial neural networks. The methodology provides a model which is able to represent the device operating in the frequency of ...

This article proposes the use of PSCAD/EMTDC to model and simulate a three-phase x-ray machine. The model is an alternative tool to power quality studies, load connection impact analysis and power factor correction in the ...

The quality requirements that consumers consider in their decision to purchase fresh fruit have garnered a great deal of attention from the actors in the fresh fruit productivity chain. This study seeks to identify attributes ...

Model-Driven Engineering a new software development paradigm concept. The paradigm predicts that software development core artifact ceases to be the code and becomes the models and software architecture. The concept does ...

Context: Software engineering aims to provide software development with high quality in short time and low cost. In this context, product quality assurance goes through all phases of development process, avoiding the ...
