We have recently shown that the widely known LMS algorithm is an H OO optimal estimator. The H OO criterion has been introduced, initially in the control theory literature, as a means to ensure robust performance in the face of model uncertainties and lack of statistical information on the exogenous signals. We extend here our analysis to the nonlinear setting often encountered in neural networ...

A new compound, dipotassium holmium(III) phosphate(V) tungstate(VI), K(2)Ho(PO(4))(WO(4)), has been obtained during investigation of the K(2)O-P(2)O(5)-WO(3)-HoF(3) phase system using the flux technique. The compound is isotypic with K(2)Bi(PO(4))(WO(4)). Its framework structure consists of flat (∞) (2)[HoPO(4)] layers parallel to (100) that are made up of (∞) (1)[HoO(8)] zigzag chains inter-li...

Previous work on automated error recognition and correction of texts written by learners of English as a Second Language has demonstrated experimentally that training classifiers on error-annotated ESL text generally outperforms training on native text alone and that adaptation of error correction models to the native language (L1) of the writer improves performance. Nevertheless, most extant m...

This paper considers hoo pertinent strands in the contemporary immigrant mental health literature: 1) the distinction made between stressors that are endemic to most immigrant experiences us. those migration stressors that precipitate trauma per se; and 2) clinical guidelines that continue to rejine the assessment of immigran ts’ presenting mental health problems, given the provision of sewices...

An Hoo controller design scheme based on the matrix fraction stability condition is proposed for the vibration control of a flexible manipulator, which has the matrix fraction uncertainty. The proposed controller is then applied to the cantilever beam with a piezoelectric-type servo-damper so that the vibration at the free end of the beam is effectively suppressed, while its effective length sl...
