this paper presents fuzzy and conventional performance of model reference adaptive control(mrac) to control a dc drive. the aims of this work are achieving better match of motor speed with reference speed, decrease of noises under load changes and disturbances, and increase of system stability. the operation of nonadaptive control and the model reference of fuzzy and conventional adaptive contr...

The adoption of product lifecycle management (PLM) business approach requires the implementation of PLM systems. Currently there is a wide variety of PLM systems in the market, but the scope differences between existing systems hamper the selection process for manufacturing companies. This paper presents a reference model for PLM systems and discusses a preliminary proposal for the evolution of...

abstract objective: homeostasis model assessment of insulin resistance (homa-ir) is a simple and practical method for estimation of insulin resistance (ir), but a reliable reference interval (ri) of homa-ir is needed to deduce the threshold level to define ir. this ri has been controversial in different populations and even more divergent when considering factors like age, gender and body mass ...

The objective of this study is to design a robust direct model reference adaptive controller (DMRAC) for a nonlinear cardiovascular model over a range of plant parameters representing a variety of physical conditions. The direct adaptive controllers used in thisd study require the plant to be almost strictly positive real (ASPR) that is, for a plant to be controlled there must exist a feedback ...

introduction accurate estimation of the absorbed dose in radiosensitive organs, located away from the target volume during radiotherapy, is one of the main reasons for the development of reference phantoms. the international commission on radiological protection (icrp) reference phantoms can provide a more realistic view of the human anatomy in comparison with the previously used mathematical p...

This report presents the MAIS (Multichannel Adaptive Information Systems) reference model. In particular, it is composed by the following models: the architectural model, to describe device components used to access services, the behavior of each component and how they interact with each other; the functional model, to describe the services and related contents, according to the double perspect...
