Quick Abstract

In the past years, there was a growing interest in teaching computational thinking in elementary and high school institutions. Although the idea is spread and well accepted among academics, it has been rarely put in practice in the classrooms. Currently, when a programming-related activity is offered, with some few exceptions, it is usually presented as an extra-curricular (optional) activity. However, it does not need to be disassociated from the common school curriculum. The present work is based on the idea that programming logic can be used transversally with different subjects, such as history, geography, science, literacy, mathematics, among others. The authors envisage to accomplish this goal by enabling programming as a supporting tool for teachers and students, allowing them to create digital interactive books. The tool, named piBook, has its main focus in the production of interactive storytelling using non-linear narratives. Besides, it is also possible to create textual games (such as role-playing games), interactive activities (such as quizzes), tutorials, chatbots and similar applications.

Quick Abstract

Aiming to facilitate the learning process of the Braille System, we developed an educational application to assist people for learning this system. We developed the application initially in Portuguese, it was named as BrailleApp, and it was designed for mobile devices, which uses the Android Platform. All accessibility standards were implemented to make it as accessible as possible to all people, helping visually impaired people and not visually impaired in the learning process of this language. In this first version, the help to learning Braille is specifically to not blind people, although, with some difficulties, it is possible a blind person use the application. In future versions we hope to improve and facilitate the use of this application by blind people too. It is important to emphasize we do not intend to replace the conventional methods which assist in this task, but to be an application to complement the already existing techniques. In an empirical analysis, the results show that the application was positive in the sense of system requirements, functionalities, and accessibility. We expect BrailleApp will be another option to assist users in the teaching-learning process and contribute to the social integration of visually impaired with technologies.

Quick Abstract

The purpose of this paper is to present a model of an mechanism Carrier Sense Multiple Access - Collision Avoidance unslotted capable of accessing the environment. This mechanism is utilized in the latest IEEE 802.15.4 standard, which defines the wireless Medium Access Control and the Physical layerspecification for Low-RateWireless Personal Area Networks. For the model construction, Hierarchical Coloured Petri Nets will be used. Hierarchical Coloured Petri Nets are extensions of Coloured Petri Nets. Design/CPN tools will be used for simulations, and the model will be verified and validated by means of occurrence graphs generation.

Quick Abstract

In the last years, many research directed for concurrency control mechanism, scheduling policy and query language in real-time database are being done. This paper presents an extensions of standard query language (SQL), called SQL-99. SQL-99 includes oriented-object functionalities. The query language for real-time database (QL-RTDB) to provide support the real-time requirements imposed the both data and transactions. A prototype implementation of the QL-RTDB is also shown.

Quick Abstract

In the last years, the demand of embedded systems has been increased. Also, due to the increasing competition among different kind of companies, such as cellular phone, automobiles and industrial automation, the requirements for such systems are getting more complex. However, the data storage and processing techniques, for these environments, are insufficient for the new requirements. In this paper, we develop a model for the integration of real-time database technology with an embedded sensor network systems, to tackle such deficiencies. Coloured Petri nets are the mathematical framework used for the modelling and analysis.
