Desenvolvimento de uma aplicação de realidade aumentada sobre conceitos de revolução e extrusão de polígonos

As aplicações mais modernas de realidade aumentada estão tendendo a colocar objetos virtuais inteligentes no cenário, de forma a reagirem aos usuários e  às condições do ambiente. Nesse sentido, este artigo trata de uma aplicação, voltada para o ensino matemático de conceitos de revolução e extrusão de polígonos, utilizando a ferramenta de autoria basAR. Isto cria um segmento de aplicações interativas de acesso a conteúdo, que possa ser utilizado como ferramenta educacional. O artigo apresenta a construção da aplicação, os conceitos envolvidos e resultados  de avaliação

The ITA Space Center and Its Role in Space Education in Brazil

This paper presents the ITA Space Center and its mission in the formation of human resources and in the research and development of space products. In 2012 the first aerospace engineers were graduated at ITA, and since then many efforts have been done to improve the engineering education. The first effort was the development of AESP-14 CubeSat project, then the development and launch of ITASAT, a 6U CubeSat. These two projects showed that small satellites projects provide a good learning approach once students were deeply involved in the development process. These two projects opened the opportunity for the creation of the ITA Space Center (CEI -acronym for Centro Espacial ITA in Portuguese). Inside its facilities the ITA Space Center provides capabilities for the development of small space projects such as electronics, software engineering, mechanical design, and simulation with the aid of systems engineering and project management. By means of the graduate and undergraduate programs the ITA Space Center is providing education and integration with the industries and other partner organizations. In developing and delivering space products, and fostering higher education in space, the ITA Space Center is accomplishing of its proposed mission

Natural language requirements boilerplates: an integrative literature review

In the field of Requirements Engineering, natural language is the most widely used form of documenting systems requirements, mainly for its expressiveness power, freedom of words, and easiness of use. On the other hand, written requirements are frequently ambiguous, incomplete, and incorrect, among other defects, impacting into the system lifecycle. To mitigate this issue, researchers have, since 1998, developed dozens of sets of boilerplates, aiding to guide natural language requirements composition. In this integrative literature review, authors searched for these sets in traditional academic databases, grey literature, and professional media, leading to a list of 54 relevant documents. Analysis of these primary works revealed that, even when boilerplate creators wish their artifacts to be used on all kinds of systems, they are generally cataloged under the Computer Science umbrella. It turned out to be evident that ambiguity is the main issue of quality of requirements addressed by boilerplates, followed by completeness and consistency. Authors mapped the requirements boilerplates definition modes, concluding that plain sentences are the foremost choice to describe these creations. It is claimed that systematization on the construction and evaluation of requirements boilerplates is still a problem to render these activities repeatable and reproducible, as the largest part of documents does not report it. Finally, the reported evaluation methods were hierarchically clustered, leading to three typical approaches for this activity
