Component repositories are commonly indicated as important resources for software reuse. In such repositories, in which independent producers and consumers can share software components, the evaluation of the quality of software components by third-party certifiers offers more security and confidence for consumers. In such a context, this paper introduces the resources supported by the XML-base...

Similar problems have similar solutions' seems a basic tenet of casebased inference. However this is not satisfied for CBR systems where the task is to achieve original solutions ?i.e. solutions that, even for 'old problems', are required to be noticeably different from previously known solutions. This paper analyzes the role of reuse in CBR systems in originality driven tasks (ODT), where a ne...

In this paper, we introducte a family of univariate Birnbaum-Saunders distributions arising from the skew-normal-t  distribution. We obtain several properties of this distribution such as its moments, the maximum likelihood estimation procedure via an EM-algorithm and a method to evaluate standard errors using the EM-algorithm. Finally, we apply these methods to a real data set to demonstr...

OBJECTIVE To investigate medical students' perception of problem based learning (PBL), to compare the acceptance level of new students who were introduced to PBL theoretically with those who had 2 years experience, and to study the effect of PBL on the academic performance. METHODS This cross-sectional study was conducted on medical students at King Abdul-Aziz University (KAU), Jeddah, Saudi ...

Part 1: description of odd nuclei in mean-field theories. Abstract In order to extract informations on pairing correlations in nu-clei from experimental mass differences, the different contributions to odd-even mass differences are investigated within the Skyrme HFB 1 method. In this first paper, the description of odd nuclei within HFB is discussed since it is the key point for the understandi...

Testing multivariate normality is an ever-lasting interest in the goodness-of-fit area since classical Pearson’s chi-squared test. Among numerous approaches construction of tests for normality, normal characterization one common approaches, which can be divided into necessary and sufficient necessary-only characterization. We construct a test by combining idea statistical representative points ...
