A universal minimal spinor set of linear differential equations describing anyons and ordinary integer and half-integer spin fields is constructed with the help of deformed Heisenberg algebra with reflection. The construction is generalized to some d = 2 + 1 supersymmetric field systems. Quadratic and linear forms of action functionals are found for the universal minimal as well as for supersym...

Hierarquias de Conceitos para um Ambiente Virtual de Ensino Extraídas de um Corpus de Jornais Populares

In this paper we present conceptual hierarchies automatically obtained from the popular newspaper Diário Gaúcho. The hierarchies were generated by means of ExATOlp tool through the extraction of noun phrases considered concept candidates by applying linguistic and statistic approaches. When accessed in a virtual learning environment, the hierarchies became a differentiated resource for vocabula...

Implementação em Java de um Algoritmo de Árvore de Decisão Acoplado a um SGBD Relacional

Nowadays one of the most researched topics in data mining is its integration with database. The reflexes of these efforts already appear in the major commercial databases, which are supplying integrated solutions of data mining. This work evaluates the coupling of an unusual decision tree algorithm to a relational database management system, and analyzes the performance of the implementation in...

Aplicação de um Checklist de Pré-Teste

The use of checklists is considered a best practice in software industry. An experiment was developed by a software organization to evaluate the impact of using a checklist to inspect and perform basic testing of software. This article presents the methodology and the results achieved.
