The paper describes an application of indexing-the technology currently widely used for processing and comparing textual information-to multi-dimensional entities of knowledge domains. We propose a model for building a frame-based ontology, which contains a domain conceptual model as well as…

A person builds his or her knowledge from different sources of information. In school he learns that Buonarroti was born in Caprese and at home they tell him that the name of the neighbor's dog is Fido. In order to…

Since the invention of magneto-optical trap (MOT), there have been several experimental and theoretical studies of the density distribution in these devices. To the best of our knowledge, only horizontal orbital traps have been observed, perpendicular to the coil axis.…

In this dissertation the GEONTO-MET methodology is presented. It is oriented to formalize the geographic domain conceptualization according to the specifications of the Instituto Nacional de Estadística, Geografía e Informática (INEGI). The main goal is to provide semantic descriptions, which…

Accurate knowledge of adult mortality levels and trends in the developing world is hampered by its widespread lack of complete vital registration systems. Although knowledge of infant and child mortality was once affect by the same problem, survey-based techniques have…

Secure multimedia communication presents new challenges that are difficult to handle using by currently adopted encryption schemes (RSA-Rivest-Shamir-Adelman, AES-Advanced Encryption Standard, and IDEA-International Data Encryption algorithm) (28). It requires the processing of huge amounts of information at speeds ranging from…

The problem of nuclear track overlapping is addressed assuming the stochastic character of charged particle registry and the fact that even monoenergetic beam perpendicularly impacting on detector surface will show a distribution for track radius values. Asymmetric distributions of overlapping…

This original article addresses the sexual and reproductive health needs of young people aged 15 to 24 in Latin America. It introduces five articles from original research projects in three countries: Argentina, Brazil, and Peru. These projects were funded by…

This article explores issues related to the relationship between everyday mathematics and academic mathematics within adult education, through a series of workshops with parents. Participants were encouraged to reflect on their perspective on learning and teaching mathematics through different activities…

Neutron spectra unfolding and dose equivalent calculation are complicated tasks in radiation protection, are highly dependent of the neutron energy, and a precise knowledge on neutron spectrometry is essential for all dosimetry-related studies as well as many nuclear physics experiments.…
