Novas políticas de divisão de nós para a Slim-tree

This paper presents two new node split policies for the Slim-tree. When compared with the previously proposed policies they result in better distribution of elements on the tree nodes. This impacts positively on the performance of similarity queries such as nearest neighbors. The experimental results show that trees built with the proposed policies outperform those built with the above with reg...

We aim, in this paper, to present a formal interacting string solution for the MigdalMakeenko Loop Wave Equation for the colour group (U(Nc)) (Ref. [1] and references therein). Our main tool to solve the Migdal-Makeenko Loop Wave Equation is based on the remark made in the Section 1 of this note, where we address the problem of solving critical string wave equations by string functional integra...

Instituto de Matemática Pura e Aplicada Simplicial

In this paper we will develop a theory for simplicial diffeomorphims, that is, diffeomorphims that preserve the incidence relations of a simplicial complex, and analyze alternative schemes to construct them with different properties. In combining piecewise linear functions on complexes with simplicial diffeomorphisms, we propose a new representation of curves and surfaces (and hypersurfaces, in...

An approach to the use of gigapixel panoramas as raw material to audiovisual narratives is presented. Through the making of the short film “Love Affair” the process is described from capturing the panoramas to the final editing of the film, considering technical and semantic aspects.
