A control strategy is described for globally stabilizing ANCBI linear plants subject to input constraints in the presence of persistent arbitrarily large but bounded disturbances. Unlike the disturbance-free case, the presence of persistent disturbances imposes critical structural conditions on the disturbance-to-state map of the system in order to achieve global internal asymptotic and global ...

This paper describes a catalytic theory that grounds cognition in biology, building on the proposals of (a) Gibson and ecological psychologists concerning the role of invariance and (b) Shepard, Gestaltists and neuroscientists concerning the role of ‘resonating’ neural waves. Enzyme catalysis increases the speed of a molecular reaction, perhaps via a type of wave, a soliton, whose formation, pe...

BACKGROUND Studies have demonstrated that perceived health-related quality of life (HRQOL) of patients receiving hemodialysis is significantly impaired. Since HRQOL outcome data are often used to compare groups to determine health care effectiveness it is imperative that measures of HRQOL are valid. However, valid HRQOL comparisons between groups can only be made if instrument invariance is dem...

This paper demonstrates the process of invariance testing in diagnostic classification models presence attribute hierarchies via an extension log-linear cognitive diagnosis model (LCDM). allows researchers to test for measurement (item) as well (structural) simultaneously a single analysis. The structural LCDM was parameterized Bayesian network, which be modeled and tested series latent regress...

An alternative account of human concept learning based on an invariance measure of the categorical stimulus is proposed. The categorical invariance model (CIM) characterizes the degree of structural complexity of a Boolean category as a function of its inherent degree of invariance and its cardinality or size. To do this we introduce a mathematical framework based on the notion of a Boolean dif...

BACKGROUND Factor analysis historically focused on measurement while path analysis employed observed variables as though they were error-free. When factor- and path-analysis merged as structural equation modeling, factor analytic notions dominated measurement discussions - including assessments of measurement invariance across groups. The factor analytic tradition fostered disregard of model te...

BACKGROUND Although the Satisfaction With Life Scale (SWLS) is the most widely used instrument to measure life satisfaction with its validation having been carried out across ages and countries, few studies have analyzed SWLS measurement cross-cultural invariance with adolescents. With respect to Spanish adolescents, measurement invariance across gender has not been found and the one-factor str...
