Current numerical constraint propagation systems accept as input only problems represented by exact numerical values and correspondingly produce only crisp solutions as output. In order to remove this limitation we have designed and implemented a generalized constraint propagation scheme based on interval arithmetic instead of conventional arithmetic. By using intervals instead of exact values ...

The paper concerns identification of the Wiener system consisting of a linear subsystem followed by a static nonlinearity f (·) with no invertibility and structure assumption. Recursive estimates are given for coefficients of the linear subsystem and for the value f (v) at any fixed v. The main contribution of the paper consists in establishing convergence with probability one of the proposed a...

This study examined the relationship between an athlete's goal perspective (i.e., task or ego orientation) and the perceived purpose of sport among male and female high school athletes. The sport-specific measure of task and ego orientation was found to have a stable factor structure and high internal consistency. Factor analysis of the Purpose of Sport Questionnaire revealed seven factors: spo...

The aim of the study was to develop an instrument for measuring the Parental Behaviors in the Context of Adolescent Disclosure (PBAD) and to examine its dimensionality, internal consistency, predictive and construct validity. The scale has been developed on the basis of a qualitative study of adolescents' views (Tokić & Pećnik, 2011) and consists of 2 subscales: the PBAD-A (antecedents of discl...

background : a multidimensional approach to health which addresses the psychological features of health justifies the necessity of designing or validation of brief instruments for screening in general population. this study aims to evaluate the reliability and validity of the persian version of the who-5-p as a brief scale of well-being. methods : in this study 451 individuals, i.e., over-15-ye...

We present a replication schema, appropriate for distributed environments where connectivity is weak, partial or variant such as in mobile information systems. The schema is based on augmenting the database interface with operations with weaker consistency guarantees. An implementation of the schema based on distinguishing copies into quasi and core is presented and protocols for enforcing it a...

Curricular changes that promote undergraduate persistence in science, technology, engineering, and mathematics (STEM) disciplines are likely associated with particular student psychological outcomes, and tools are needed that effectively assess these developments. Here, we describe the theoretical basis, psychometric properties, and predictive abilities of the Persistence in the Sciences (PITS)...

OBJECTIVE To evaluate the self-esteem of cancer patients undergoing chemotherapy. METHOD Descriptive analytical cross-sectional study with a quantitative approach. Around 156 patients that attended an oncology unit of a mid-sized hospital participated in the study. RESULTS We found a higher frequency of patients with high self-esteem, but some of them showed average or low self-esteem. The ...

The present study presents preliminary evidence regarding the reliability and validity of the Multidimensional Inventory of Black Identity (MIBI). The MIBI consists of 7 subscales representing 3 stable dimensions of African American racial identity (Centrality, Ideology, and Regard). Responses to the MIBI were collected from 474 African American college students from a predominantly African Ame...

With reference to nunierical iterative algorithnis, this paper exemplifies a methodology to design the runtime support uf applications sharing N set of datu structures on a distributed nieniory architectire. According to the methodology, the support is decomposed into two layers: an application independent one, supplying the basic functionalities to access a shared strucfure, and an application...
