A reference model as automated process for software adaptation at runtime

The development of self-adaptive software (SaS) has specific characteristics compared to traditional one, since it allows that changes to be incorporated at runtime. Automated processes have been used as a feasible solution to conduct the software adaptation at runtime. In parallel, reference model has been used to aggregate knowledge and architectural artifacts, since capture the systems essence of specific domains. However, there is currently no reference model based on reflection for the development of SaS. Thus, the main contribution of this paper is to present a reference model based on reflection for development of SaS that have a need to adapt at runtime. To present the applicability of this model, a case study was conducted and good perspective to efficiently contribute to the area of SaS has been obtained.

A quantum theory for the excitation spectrum of a rectangular Andreev billiard

We consider a N - S box system consisting of a rectangular conductor coupled to a superconductor. The Green functions are constructed by solving the Bogoliubov-de Gennes equations at each side of the interface, with the pairing potential described by a step-like function. Taking into account the mismatch in the Fermi wave number and the effective masses of the normal metal - superconductor and the tunnel barrier at the interface, we use the quantum section method in order to find the exact energy Green function yielding accurate computed eigenvalues and the density of states. Furthermore, this procedure allow us to analyze in detail the nontrivial semiclassical limit and examine the range of applicability of the Bohr-Sommerfeld quantization method.

Origami e kirigami: arte e cultura como recurso lúdico e educativo

We can know a people through their cultural and artistic assets. One of the many aspects of Japanese culture is origami, a fusion of the verb “oru”, which means folding, with the word “kami” meaning paper. In this communication, we describe the course “Origami and Kirigami: art and culture as a recreational and educational resource”. The course aimed to present these two oriental techniques based on paper and its potential as a source of entertainment and education, at the same time seeking to introduce cultural aspects of these arts of folding and/or cutting paper. This practice is more common than we realize, and is present in our day-to-day life when we perform actions such as folding clothes and papers, and making packages, amongst others. However, few are aware of the benefits that this folding brings to the fields of Arts, Mathematics, and Science, besides its recreational characteristics. Kirigami is a mixed technique that in addition to using folds in the paper (as in origami) also uses cuts (“kiru” – meaning, “cut”). It can be performed with heavier paper than origami, and by introducing some cuts, the paper can be folded to form the desired shape. It is a simple technique, with impressive results. We conducted eight weekly meetings, each lasting four hours, totaling 32 hours of coursework. In addition to the classes, a visit was made to the Okinawa Club in Bauru (São Paulo), where it was possible for the students of the course and the elderly group (fujinkai) of origamists of the club to exchange experiences. Finally, an exhibition was organized to display the artifacts produced by the course participants and disseminate the work of the students.

Pano Kente: estrutura e estética africana

The fractal geometry of nature is seen in organizations and has set handcrafted artifacts, among them African Kente cloth traditionally produced by Ewe and Ashanti of West Africa. Incorporating parameters also classify products as carriers of fractal geometry, the Kente fabrics exhibit built from geometric shapes classified as seeds or unique architecture. This article aims to analyze examples of Kente cloths and establish the existence of geometric structures formed from a parent cell, exposing how this cell and how its architecture and formed patterns are maintained throughout the finished product.

Aplicação de métodos ergonômicos na avaliação de ferramentas produzidas e utilizadas por homens na Pré-História

The study of prehistoric artifacts may contribute to understand the development of these artifacts, and also of ergonomics. This study aims to investigate and identify the types of grips of two Brazilian stone tools (scraper / piercer and a slug) approximately 5000 years old through the use of gloves with sensors and contact maps of the hand palm, exploring the best method for research of ergonomics in prehistory. Hence it can contribute to the discussion of a part of the ergonomics’ history that remains underexplored.
