Um método para desenvolvimento de abordagens generativas com composição de linguagens específicas de domínio

The software systems development with domain-specific languages has become increasingly common. Domain-specific languages (DSLs) provide increased of the domain expressiveness, raising the abstraction level by facilitating the generation of models or low-level source code, thus increasing the productivity of systems development. Consequently, methods for the development of software product lines and software system families have also proposed the adoption of domain-specific languages. Recent studies have investigated the limitations of feature model expressiveness and proposing the use of DSLs as a complement or substitute for feature model. However, in complex projects, a single DSL is often insufficient to represent the different views and perspectives of development, being necessary to work with multiple DSLs. In order to address new challenges in this context, such as the management of consistency between DSLs, and the need to methods and tools that support the development with multiple DSLs, over the past years, several approaches have been proposed for the development of generative approaches. However, none of them considers matters relating to the composition of DSLs. Thus, with the aim to address this problem, the main objectives of this dissertation are: (i) to investigate the adoption of the integrated use of feature models and DSLs during the domain and application engineering of the development of generative approaches; (ii) to propose a method for the development of generative approaches with composition DSLs; and (iii) to investigate and evaluate the usage of modern technology based on models driven engineering to implement strategies of integration between feature models and composition of DSLs

Lazer e urbanização: a dinâmica do setor de serviços no litoral de Parnamirim e Nísia Floresta - RN

The research here undertaken analyzes the process of urbanization on the coast of Panamirim - RN and Nísia Floresta - RN, arising from leisure, the main leisure expression was considered the second residence and coastal tourism. The leisure promoted the growth of businesses and public and private services to meet consumer demand in that area, which initially occurred with users of second home, and which also gradually begin to occupy the coastline of these municipalities in 1980 and more recently with the development of tourism in the 1990s until now. To undertake such an analysis, we did the georeferencing about the trade and also public and private services of that coast, characterizing them; evaluated the extent to which services deployed in this area meets the demands of tourists and users of second residence; it was also identified how the centrality of Natal interferes in the expansion of services in these locations. The spatial area of research includes the coastal municipalities of Parnamirim and Nísia Floresta, considering the limits of the census of the Instituto Brasileiro de Geografia e Estatística- IBGE, and about the time frame, it was considered the 1990s to the present day. The methodology consists of: 1. survey and reading of the literature related to the researched topic, serving as the theoretical analysis in the construction of the object studied; 2. collection and organization of secondary data by the IBGE and tourism sectors of the State of Rio Grande do Norte, Natal and main municipalities of the research; 3. Questionnaires and / or interviews with the traders, service providers, tourists, users of second homes, local residents, and government. The analysis of such data collected allowed the preparation of graphs, maps and tables that illustrate the results obtained in the research field, basing so the study. The relevance of the study is shown by the extensive survey data involving agents of the research, including tourists, users of second homes and, above all, the data for the service sector that did not exist in the analyzed area. The study results identified in the area analyzed the emergence of three new centers, arising from the urbanization process from leisure, one of them located in the municipality of Nísia Foresta Beach in Barra de Tabatinga, and two in Parnamirim, more specifically in locality Pium and Beach Pirangi do Norte. It was further observed that, being located in tourist areas, the main feature of these new centers is seasonality

Em busca do estado participativo: os desafios da participação social na gestão ambiental

The existence of several negative indicators such as deforestation, pollution of rivers and urban growth disorderly suggest a scenario of serious environmental degradation in Brazil, allowing that the model of public management of the environment here is not practiced efficiently, despite to be a recognition-of environmental legislation as one of the best and most comprehensive in the world. One of the main causes of this problem is the low social participation in environmental management that often exists only in the formal plan. Thus, although defined as Democratic State, in practice, it is only a Figurative State. Based on the study of the origin of the state and social participation in the Brazilian State, in general scope, and some environment committees and public hearings in Rio Grande do Norte, as instruments of social control, in particular scope, it is possible to build a real Democratic State in environmental management, a Participative State, in which all players are aware of the responsibility and committed to the duty assigned to them by the constitutional text with the present and future generations

Fatores de sucesso ou insucesso do turismo ambientalmente sustentável : percepção das autoridades públicas no pólo costa das dunas do Rio Grande do Norte

This study aims to compare the thermal performance of tiles made from recycled material (waste packaging cardboard with aluminized film) with the tiles of fiber and bitumen, fiber cement and red ceramic with the aim of verifying the suitability of tile to be used in hot and humid climate of low latitude. The samples were selected according to the availability from Natal RN market, as they are sold to the consumers. The methodology was based on studies that used experimental apparatus composed of thermal chambers heated by banks of incandescent bulbs, to analyze the thermal performance of materials. The tiles in the study were submitted to analysis of thermal performance, thermophysical properties and absorptance, using chambers of thermal performance, measuring the thermophysical properties and portable spectrometer, respectively. Comparative analysis of thermal performance between two samples of the recycled material with dimple sizes and different amounts of aluminum were made, in order to verify, if these characteristics had some interference on the thermal performance of them; the results showed no significant performance differences between the samples. The data obtained in chambers of thermal performance and confirmed by statistical analysis, showed, that the tile of recycled material have similar thermal performance to the tile of fiber cement. In addition to these tests was carried out the automatic monitoring of a building covered with tiles of recycled material, to verify its thermal performance in a real situation. The results showed that recycled shingles must be used with technical criteria similar to those used for fiber cement tiles, with regard to the heat gain into the building. Within these criteria should be taken into account local characteristics, especially in regions with hot and humid climate, and its use must be associated, according to the literature, to elements of thermal insulation and use of passive techniques such as vented attics, ceilings and right foot higher

Fundamentação cinética da estatística não gaussiana : efeitos em politrópicas

Considering a non-relativistic ideal gas, the standard foundations of kinetic theory are investigated in the context of non-gaussian statistical mechanics introduced by Kaniadakis. The new formalism is based on the generalization of the Boltzmann H-theorem and the deduction of Maxwells statistical distribution. The calculated power law distribution is parameterized through a parameter measuring the degree of non-gaussianity. In the limit = 0, the theory of gaussian Maxwell-Boltzmann distribution is recovered. Two physical applications of the non-gaussian effects have been considered. The first one, the -Doppler broadening of spectral lines from an excited gas is obtained from analytical expressions. The second one, a mathematical relationship between the entropic index and the stellar polytropic index is shown by using the thermodynamic formulation for self-gravitational systems

Física estatística aplicada a sistemas sociais através do estudo de redes complexas

In this work a study of social networks based on analysis of family names is presented. A basic approach to the mathematical formalism of graphs is developed and then main theoretical models for complex networks are presented aiming to support the analysis of surnames networks models. These, in turn, are worked so as to be drawn leading quantities, such as aggregation coefficient, minimum average path length and connectivity distribution. Based on these quantities, it can be stated that surnames networks are an example of complex network, showing important features such as preferential attachment and small-world character

Os princípios de universalidade, integralidade e eqüidade do SUS só podem ser viabilizados com a construção de um modelo de financiamento flexível e transparente que permita o controle social e ofereça a agilidade no uso dos recursos. Este artigo analisa as dificuldades e desafios do financiamento da saúde bucal na ótica de gestores e técnicos da área. A coleta de dados ocorreu por meio de entrevistas, queforam gravadas e transcritas para análise qualitativa, preconizada por Bardin. As dificuldades relatadas pelos entrevistados foram expressas em frases como: Procuro cumprir a agenda, porém muita coisa não consegui devido à falta de recursos, não se sabe o quanto pode gastar, escassez de recursos para procedimentos de média e grande complexidades, falta de recurso para troca de equipamento e prioridade para compra de materiais. No que tange aos desafios foi relatada a necessidade de capacitação, formação e organização dos recursos humanos em saúde pública. Observa-se a dificuldade na realização completa do plano previsto de gestão, assim como a necessidade de compromisso por parte dos gestores em acompanhar as etapas de todo processo de repasse financeiro e aplicação do mesmo.

A utilização da estatística na Ortodontia

A estatística exerce um papel fundamental no método científico, a qual se preocupa em organizar, descrever, analisar e interpretar os dados obtidos a partir de uma observação ou de um experimento. Todavia, ela continua sendo pouco acessível na interpretação, seja por parte do leitor ou por parte daquele que a utiliza. Às vezes, a estatística é mal aplicada ou não compreendida devido aos termos, com significado próprio. Além disso, existem poucos artigos científicos da área de Ortodontia relacionados com este assunto. Assim, o presente artigo propõe realizar um levantamento sobre as freqüências do uso da estatística, fazer considerações sobre a seleção dos seus métodos e explanar sobre as possíveis interpretações dos resultados.

Aplicação da abordagem estatística no contexto da gestão da qualidade: um survey b com indústrias de alimentos de São Paulo

Nas últimas duas décadas, o crescimento do interesse pela metodologia Seis Sigma intensificou a aplicação da abordagem estatística e de outras abordagens quantitativas com o intuito de melhorar não apenas a qualidade de produtos, serviços e processos, como também aumentar o desempenho organizacional e o processo de tomada de decisão. Este artigo trata da aplicação da abordagem estatística no contexto da gestão da qualidade em indústrias de alimentos de médio e grande porte do Estado de São Paulo com o propósito de: identificar quais ferramentas e técnicas estatísticas são mais amplamente empregadas por indústrias do setor para garantir e controlar a qualidade; avaliar a interdependência entre o sucesso da implementação de programas de qualidade e segurança alimentar como Boas Práticas de Fabricação (BPF) e sistema de Análise de Perigos e Pontos Críticos de Controle (APPCC) e o uso de estatística; e analisar estimativas do grau de relevância do pensamento estatístico e de seus benefícios como ferramenta de melhoria da qualidade. Um survey exploratório-descritivo foi realizado e os resultados revelaram que a abordagem estatística começa a ser mais valorizada nas indústrias de alimentos pela relevância de seus benefícios assim como já ocorre em outros setores. Há evidências de que a implantação bem sucedida dos programas de segurança alimentar seja uma condição primordial para o uso efetivo de estatística e de outras abordagens quantitativas.
