A Reference Architecture based on Reflection for Self-adaptive Software

Self-adaptive Software (SaS) presents specific characteristics compared to traditional ones, as it makes possible adaptations to be incorporated at runtime. These adaptations, when manually performed, normally become an onerous, error-prone activity. In this scenario, automated approaches have been proposed to support such adaptations; however, the development of SaS is not a trivial task. In parallel, reference architectures are reusable artifacts that aggregate the knowledge of architectures of software systems in specific domains. They have facilitated the development, standardization, and evolution of systems of those domains. In spite of their relevance, in the SaS domain, reference architectures that could support a more systematic development of SaS are not found yet. Considering this context, the main contribution of this paper is to present a reference architecture based on reflection for SaS, named RA4SaS (Reference Architecture for SaS). Its main purpose is to support the development of SaS that presents adaptations at runtime. To show the viability of this reference architecture, a case study is presented. As result, it has been observed that RA4SaS has presented good perspective to efficiently contribute to the area of SaS.

Cartas pessoais entre crianças brasileiras, portuguesas e angolanas

This article analyzes the data resultant of the accomplishment, between 2008 and 2009, of an extension and research project on the international exchange of letters between teachers and students from elementary schools in the towns of Garça and Marília, São Paulo State, Brazil, with a school in the city of Azaruja, Portugal and another in the city of Luanda, Angola. It was developed by a team of students and teachers, UNESP, Marília, in order to promote the exchange via personal letters for that students, between 8 and 9 years old, could take possession of the written language, in this case Portuguese, and understand it as an instrument steeped in culture. The choice of this kind in the world of the epistolary genre was made because it promotes the participation of the Other in the configuration of dialogic relations in the elaboration of the statements, taken as a reference in a Bakhtinian conception of language. It aimed to (1) point, in the letters exchanged between teachers and students between the Portuguese, Brazilians and Angolans in the early years, the evidence of authorship linguistic behavior that could signal the beginning of autonomy in the use of the written modality of language, or signs of submissive behavior; (2) reveal the cultural content of language tools used to construct indicators listed on the customs of each people, including those constituting school doings. For the generation of data were used principles of action research, which enabled direct action, along with Brazilian teachers, and indirectly, in the case of the foreign teachers. From the analysis of the corpus of research - letters exchanged between teachers and students - it is clear that the appropriation of language as a speech act realized in human relations makes the old personal correspondence a powerful instrument of development in the area of the written language.

O novíssimo Príncipe: Gramsci e a reconstrução da teoria marxista do Partido

It is only in his Prison Notebooks, through the political formula crystallized in the 'Modern Prince', that gramscian theory of the political party reaches its final configuration. Beyond to direct dialogue with the leninian formulations and those subsequently developed by the Communist International, is also noticeable echoes of critical dialogue with elitist sociology of the political party of Robert Michels. Largely, is thanks to this critical and nonsectarian approach that Gramsci could produce one of the most original reflection on the party organization within the Marxist tradition, facing the issues previously neglected of oligarchyzation and bureaucratization of workers' parties, thus providing a possible theoretical overrun for the inevitability of elitist thesis of split between the party leader's core interests and the interests of their social reference. The objective of this work is to restore some contributions of Gramsci to the reconstruction of theory of the revolutionary party today.

Larval development of indigenous South American freshwater fish species, with particular reference to pacu (Piaractus mesopotamicus): A review

In recent years, a number of South American freshwater fish have gained increasing attention for their potential in aquaculture, not only because of their excellent performance in farming systems but also to meet the high consumer demand for these species due to declining fishery resources. Many South American freshwater species are migratory and produce altricial larvae, with a small amount of yolk reserves. Unlike precocial freshwater species and altricial coldwater marine fish, these freshwater fish investigated have rapid yolk depletion and metamorphosis. Specific studies on the initial development of South American fish are scarce and fragmented. One of the most widely studied species is the pacu (Piaractus mesopotamicus), farmed in warm continental waters. In the present review we compile new and published data on the initial development of pacu, including morphogenesis of the skeletal, muscle, digestive and sensory systems; compare it to other Neotropical species; and discuss the importance of this information to develop larviculture protocols. When pacu larvae exhaust yolk reserves, they initiate a new form of interaction with the environment, becoming exclusively exotrophic. This type of interaction is made possible by the rapid development of sensory, skeletal, locomotor and digestive structures. In addition to understanding fish ontogeny, studies on larval development are necessary to improve farming systems and larviculture techniques aimed at producing high-quality juveniles in aquaculture.

Preparos dentais para coroas totais anteriores cerâmicas

The aim of this study is to describe, illustrate and discuss a simple, effective and rational method for preparing anterior all-ceramic restorations. This procedure uses a reduced number of diamond burs and a few clinical steps. The biological, mechanical, functional and aesthetic principles are obtained in a reasonable manner, regarding the requirements’ supported by the contemporary aesthetic dentistry. At the end of reading, it is expected that the professionals understand the design of the axial and cervical dental walls. Finally, the dental preparations will be made in a rapid and efficient manner. Despite the citation of specific diamond burs, it is expected that the reader use them as a reference. The understanding of their geometric configuration and volume are more important than their manufacturer’s reference number. Other manufacturers have diamond burs with the same geometric configuration of those recommended in this technique. Thus, the clinical professional must select the diamond points according to their manufacturer of choice.

Estimation methods of reference evapotranspiration (ETo) for Uberlândia -MG

One approach to verify the adequacy of estimation methods of reference evapotranspiration is the comparison with the Penman-Monteith method, recommended by the United Nations of Food and Agriculture Organization - FAO, as the standard method for estimating ET0. This study aimed to compare methods for estimating ET0, Makkink (MK), Hargreaves (HG) and Solar Radiation (RS), with Penman-Monteith (PM). For this purpose, we used daily data of global solar radiation, air temperature, relative humidity and wind speed for the year 2010, obtained through the automatic meteorological station, with latitude 18° 91' 66 S, longitude 48° 25' 05 W and altitude of 869m, at the National Institute of Meteorology situated in the Campus of Federal University of Uberlandia - MG, Brazil. Analysis of results for the period were carried out in daily basis, using regression analysis and considering the linear model y = ax, where the dependent variable was the method of Penman-Monteith and the independent, the estimation of ET0 by evaluated methods. Methodology was used to check the influence of standard deviation of daily ET0 in comparison of methods. The evaluation indicated that methods of Solar Radiation and Penman-Monteith cannot be compared, yet the method of Hargreaves indicates the most efficient adjustment to estimate ETo.

Reference evapotranspiration models using different time scales in the Jaboticabal region of Sao Paulo, Brazil

The aim of this paper is to compare 18 reference evapotranspiration models to the standard Penman-Monteith model in the Jaboticabal, Sao Paulo, region for the following time scales: daily, 5-day, 15-day and seasonal. A total of 5 years of daily meteorological data was used for the following analyses: accuracy (mean absolute percentage error, Mape), precision (R-2) and tendency (bias) (systematic error, SE). The results were also compared at the 95% probability level with Tukey's test. The Priestley-Taylor (1972) method was the most accurate for all time scales, the Tanner-Pelton (1960) method was the most accurate in the winter, and the Thornthwaite (1948) method was the most accurate of the methods that only used temperature data in the equations.

The effect of offset implant configuration on bone stress distribution: a systematic review

Purpose: The aim of this systematic review was to compare straight-line and offset implant configurations for three-element implant-retained prostheses. Materials and Methods: Two independent reviewers conducted a review on PubMed/Medline, EMBASE, and Cochrane Library for studies published in English, from January 1, 1995 to January 17, 2014. A systematic review was conducted following the PRISMA statement. All relevant titles were selected according to inclusion/exclusion criteria. From this pool of titles, abstracts and full texts were reviewed. Results: A total of 6080 titles were identified with the initial search. Twenty-one were selected based on title and abstract. Of these, after discussion and complete reading, 12 studies were selected according to the inclusion and exclusion criteria, all of which were in vitro studies. Conclusions: A systematic review of the current literature showed only in vitro evidence that there is no consensus on the advantage of using an offset configuration implant compared to those in straight-line configuration, even though some studies present a slight improvement of bone stress distribution when an offset implant is under oblique loading (PICO).
