Desenvolvimento de sistemas orientado a modelos

The Software Engineering originated with the motivation to mass produce components for increased productivity in production systems. Since its origins, numerous studies have been proposed on the subject as new features in the creation of systems, like the Object- Oriented Programming and Aspect-Oriented Programming, have been established and methodologies have been developed to control them efficiently. However, years of studies in the area were not sufficient to create a methodology for reusing software artifacts really efficient and easy enough to be widespread. Given this, the Model-Driven Development (MDD) is trying to promote it using the modeling of systems as a reference, becoming part of it and establishing a huge productivity gain. One of his approaches is called Model-Driven Software Development (MDSD), which focuses on improving the practices and systems development using Domain-Specific Languages (DSL) for this purpose. In this Final Paper, Xtext is used as a tool to prove the productivity and efficiency of this approach, and for that bibliographic studies were made on the approach and the tool, and show the methodology and a case study to demonstrate results and conclusions regarding this work

Joint economic design of X̄ and R control charts for processes subject to two independent assignable causes

A model for the joint economic design of X̄ and R control charts is developed. This model assumes that the process is subject to two assignable causes. One assignable cause shifts the process mean; the other shifts the process variance. The occurrence of the assignable cause of one kind does not block the occurrence of the assignable cause of another kind. Consequently, a second process parameter can go out-of-control after the first process parameter has gone out-of-control. A numerical study of the cost surface to the model considered has revealed that it is convex, at least in the interest region.

Planejamento paisagístico do Campus Universitário da Faculdade de Ciências Agronômicas, UNESP, Botucatu, S.P

O Planejamento Paisagístico do Campus da Faculdade de Ciências Agronômicas da Universidade Estadual Paulista (UNESP) em Botucatu - SP, foi elaborado a partir de um Plano Diretor já existente e considerado o comportamento da paisagem, com edificações e circulações já estabelecidas, dando ênfase ao projeto de ajardinamento do entorno da Central de Salas de Aulas. Os objetivos principais do planejamento visam a proteção do solo, arborização adequada e ajardinamento do encontro dos prédios principais. O traçado proposto é simples, com a finalidade de dar uma escala humana ao Campus, considerando a necessidade dos usuários e de favorecer a utilização de máquinas para manutenção e tratos culturais, em face da pequena disponibilidade de mão-de-obra, sendo mais elaborado somente nos entornos dos prédios principais. A estrutura vegetal é formada de árvores, arbustos, gramados e outras forrações que foram selecionadas por sua rusticidade, resistência, aclimatação ao local e disponibilidade nos Viveiros Experimentais da Faculdade de Ciências Agronômicas-UNESP.

Robust control to parametric uncertainties in smart structures using linear matrix inequalities

The study of algorithms for active vibrations control in flexible structures became an area of enormous interest, mainly due to the countless demands of an optimal performance of mechanical systems as aircraft and aerospace structures. Smart structures, formed by a structure base, coupled with piezoelectric actuators and sensor are capable to guarantee the conditions demanded through the application of several types of controllers. This article shows some steps that should be followed in the design of a smart structure. It is discussed: the optimal placement of actuators, the model reduction and the controller design through techniques involving linear matrix inequalities (LMI). It is considered as constraints in LMI: the decay rate, voltage input limitation in the actuators and bounded output peak (output energy). Two controllers robust to parametric variation are designed: the first one considers the actuator in non-optimal location and the second one the actuator is put in an optimal placement. The performance are compared and discussed. The simulations to illustrate the methodology are made with a cantilever beam with bonded piezoelectric actuators.

H ∞ state feedback control of discrete-time Markov jump linear systems through linear matrix inequalities

This paper addresses the H ∞ state-feedback control design problem of discretetime Markov jump linear systems. First, under the assumption that the Markov parameter is measured, the main contribution is on the LMI characterization of all linear feedback controllers such that the closed loop output remains bounded by a given norm level. This results allows the robust controller design to deal with convex bounded parameter uncertainty, probability uncertainty and cluster availability of the Markov mode. For partly unknown transition probabilities, the proposed design problem is proved to be less conservative than one available in the current literature. An example is solved for illustration and comparisons. © 2011 IFAC.

Biodiversity Can Help Prevent Malaria Outbreaks in Tropical Forests

Background: Plasmodium vivax is a widely distributed, neglected parasite that can cause malaria and death in tropical areas. It is associated with an estimated 80-300 million cases of malaria worldwide. Brazilian tropical rain forests encompass host- and vector-rich communities, in which two hypothetical mechanisms could play a role in the dynamics of malaria transmission. The first mechanism is the dilution effect caused by presence of wild warm-blooded animals, which can act as dead-end hosts to Plasmodium parasites. The second is diffuse mosquito vector competition, in which vector and non-vector mosquito species compete for blood feeding upon a defensive host. Considering that the World Health Organization Malaria Eradication Research Agenda calls for novel strategies to eliminate malaria transmission locally, we used mathematical modeling to assess those two mechanisms in a pristine tropical rain forest, where the primary vector is present but malaria is absent. Methodology/Principal Findings: The Ross-Macdonald model and a biodiversity-oriented model were parameterized using newly collected data and data from the literature. The basic reproduction number (R0) estimated employing Ross-Macdonald model indicated that malaria cases occur in the study location. However, no malaria cases have been reported since 1980. In contrast, the biodiversity-oriented model corroborated the absence of malaria transmission. In addition, the diffuse competition mechanism was negatively correlated with the risk of malaria transmission, which suggests a protective effect provided by the forest ecosystem. There is a non-linear, unimodal correlation between the mechanism of dead-end transmission of parasites and the risk of malaria transmission, suggesting a protective effect only under certain circumstances (e.g., a high abundance of wild warm-blooded animals). Conclusions/Significance: To achieve biological conservation and to eliminate Plasmodium parasites in human populations, the World Health Organization Malaria Eradication Research Agenda should take biodiversity issues into consideration. © 2013 Laporta et al.

Evaluating interaction with websites: Case study of a government website of the Brazilian Ministry of labor and employment

30° inclination in handles of plastic boxes can reduce postural and muscular workload during handling

CONTEXTUALIZAÇÃO:O manuseio de materiais está ainda presente nos setores industriais e é associado a lesões na coluna lombar e membros superiores. A inserção de alças em caixas industriais é uma forma de reduzir os riscos relacionados à tarefa, porém a posição e a angulação das alças, que são fatores importantes para o conforto e segurança durante o manuseio, são ainda pouco investigadas objetivamente.OBJETIVOS:Comparar o manuseio de uma caixa comercial e de protótipos com alças e avaliar seus efeitos na postura de membros superiores, atividade elétrica muscular e percepção de agradabilidade em diferentes empunhaduras durante manuseio entre diferentes alturas.MÉTODO:Trinta e sete voluntários saudáveis avaliaram as alças dos protótipos que possibilitavam mudança nas posições (superior e inferior) e angulações (0°, 15° e 30º). Os movimentos dos punhos, cotovelos e ombros foram avaliados por meio da eletrogoniometria e inclinometria. A atividade elétrica muscular dos extensores do punho, bíceps braquial e porção superior do trapézio foi avaliada por um eletromiógrafo portátil. Os registros de movimento e atividade elétrica muscular foram sincronizados. Aspectos subjetivos de agradabilidade foram avaliados por meio de uma escala visual analógica.RESULTADOS E CONCLUSÕES:Os protótipos com alças inclinadas em 30° apresentaram as melhores avaliações de agradabilidade, posturas mais neutras de punho, menores níveis de atividade eletromiográfica do trapézio superior e menores ângulos de elevação dos braços. Os diferentes métodos de medida se mostraram complementares para a avaliação dos membros superiores durante as tarefas de manuseio.
