Ferramentas de Apoio à Criação e Edição de Ontologias: Tainacan Ontology e uma Análise Comparativa

With the need to handle large amounts of data on the web, and treat this data as significant knowledge, the Web of Data has migrated to a new paradigm, the Semantic Web. Ontologies composes the core of the semantic web, and to develop it is necessary to use tools called ontologies editors. This article presents a comparative analysis of these tools, focused on providing functionality based on O...

Taking a gender perspective, the current study seeks to evaluate access to a specialized HIV/AIDS service in Salvador, Bahia, identifyin...

Lecture 14 — Thursday , Oct 17 2013

Proof. For the m = d case, first rotate the subspace W to become span(e1, . . . , ed) (via multiplication by an orthogonal matrix), and then project to the first d coordinates. This clearly preserves norms in W exactly. Now, assume there is an ε-subspace embedding Π ∈ Rm×n for m < d. Then, the map Π : W → Rm has a nontrivial kernel, in particular there is some w ∈ W,w 6= 0 such that Πw = 0. On ...

Les invaginations intestinales chez l’adulte: à propos de 17 cas

L'invagination intestinale est une affection rare chez l’adulte. Elle conduit le plus souvent à la découverte d’une cause organique pouvant être tumorale. Le but de notre travail est de dégager les particularités épidémiologiques diagnostiques et thérapeutiques de cette affection; à travers une étude descriptive rétrospective, ayant portée sur 17 cas d'invagination intestinale de l'adulte opéré...
