This paper presents a direct adaptive control scheme for nonminimum phase systems in which controller parameters are estimated from the recursive least-squares algorithm, and additional auxiliary parameters are obtained from the proposed polynomial identity. A local convergence is guaranteed without any extra condition. Integral action is incorporated into the adaptive controller to eliminate t...

Two hundred and eighteen bi-rooted niaxillar\' premolars were examined radiogra]3hicall\' to determine the length from the apex at which root curvature occurred. The information may serve as a guide in determining ]:)ost preparation length. T h e result.s of the study indicated that the lingual root was slightly straighter than the buecal root. 'I'lie curvature of the root was on the average 6....

The paper demonstrates that product configuration applications fit naturally the framework of answer set programming. It is shown that product configuration knowledge can be represented systematically and compactly using a logic program type rule language such that the answers of a configuration task, the configurations, correspond to the models of the rule representation.. The paper pr.es.~nts...

an analysis of seasonal rainfall over iran for a period of 30 years (1971-2000) shows a significant variability in spatial and temporal distributions of rainfall as well as its frequency and intensity. in this paper, the likely effects of enso on the rainfall anomalies are investigated. the accumulated monthly and seasonal rainfalls from 43 synoptic stations are taken through the islamic republ...

The title of my paper comes from an essay by Václav Havel. In his essay, Havel addressed most evocatively the question of the unique power of words for thinking and to influence, for good or for harm, as well as to inform and to educate. As analysts our medium is the word. I suggest that it is of inestimable importance that we are able to listen deeply to our patients' words and to be aware of ...

In this note we describe the notion of a rectifiable scan and consider some applications [DH1], [DH2] to Plateau-type minimization problems. “Scans” were first introduced in the work [HR1] of Tristan Rivière and the second author to adequately describe certain bubbling phenomena. There, the behavior of certain W 1,3 weakly convergent sequences of smooth maps from 4 dimensional domains into S le...

Conservation attention on charismatic large vertebrates such as dolphins is often supported by the suggestion that these species represent surrogates for wider biodiversity, or act as indicators of ecosystem health. However, their capacity to act as indicators of patterns or trends in regional biodiversity has rarely been tested. An extensive new dataset of >300 last-sighting records for the Ya...

Ross River virus (RRV) infection is a debilitating disease that has a significant impact on population health, economic productivity, and tourism in Australia. This study examined epidemiologic patterns of RRV disease in Queensland, Australia, during January 2001-December 2011 at a statistical local area level. Spatio-temporal analyses were used to identify the patterns of the disease distribut...

A reassortant, TyRh, was isolated after coinfection of MA104 cells with avian Ty-1 and simian RRV rotaviruses. Hybridization and serological studies showed that the reassortant's 4th gene, which encodes Vp4, was derived from the simian RRV rotavirus parent, whereas the remaining 10 genes were derived from the avian Ty-1 rotavirus parent.

Beat-to-beat variability of the QT interval (QTV) is sought to provide an indirect noninvasive measure of sympathetic nerve activity, but a formal quantification of this relationship has not been provided. In this study we used power contribution analysis to study the relationship between QTV and muscle sympathetic nerve activity (MSNA). ECG and MSNA were recorded in 10 healthy subjects in the ...
