This paper gives an introduction to recent work on the problem of quantifying errors in the estimation of models for dynamic systems. This is a very large eld. We therefore concentrate on approaches that have been motivated by the need for reliable models for control system design. This will involve a discussion of eeorts which go under the titles of`Estimation in H 1 ', `Worst Case Estimation'...

The paper describes an extension of PROSPEC, a system to represent enterprises model-based to derive from the “deep” knowledge of the business processes requirements for a Quality Management System. Especially, features demanded by the new ISO 9000:2000 for such systems such as continuos improvement and determination of customer requirements are addressed. The development of the enterprise mode...

This study aimed to empirically develop a reliable and valid model specifically for measuring service quality of sport conferences as sport event tourism. To assess the model which has been established based on the survey, data gathered from 136 of attendees in sport conference. Finding of this study showed that participants form their service quality perceptions based on their evaluations of 4...

phytoplankton and zooplankton concentrations in pishin reservoir are predicted employing a three-dimensional numerical model in this paper. modeling is performed using a numerical model based on mass transport equation. advection, diffusion and source/sink processes are considered as separate subroutines for predicting the concentrations of phytoplankton and zooplankton in the reservoir. finit...

This work presents a classification for the management of QoSenabled networks. This classification shows that a solution for an integrated management is required. Thus, a model for integrated QoS management is proposed. Such model is analyzed through the implementation of the QAME (QoS-Aware Management Environment) prototype. Resumo. Este trabalho apresenta uma classificação para as pesquisas r...

Usually efficiency is defined in energetic terms without taking into account the quality of the energy. Another way to analyse and optimise processes and systems is in terms of exergy. The concept of exergy incorporates both qualitative and quantitative properties of energy. Exergy analysis makes the exact determination of the energetic and resource saving potential of industrial processes or s...
