The geological modeling allows, at laboratory scaling, the simulation of the geometric and kinematic evolution of geological structures. The importance of the knowledge of these structures grows when we consider their role in the creation of traps or conduits to oil and water. In the present work we simulated the formation of folds and faults in extensional environment, through physical and numerical modeling, using a sandbox apparatus and MOVE2010 software. The physical modeling of structures developed in the hangingwall of a listric fault, showed the formation of active and inactive axial zones. In consonance with the literature, we verified the formation of a rollover between these two axial zones. The crestal collapse of the anticline formed grabens, limited by secondary faults, perpendicular to the extension, with a curvilinear aspect. Adjacent to these faults we registered the formation of transversal folds, parallel to the extension, characterized by a syncline in the fault hangingwall. We also observed drag folds near the faults surfaces, these faults are parallel to the fault surface and presented an anticline in the footwall and a syncline hangingwall. To observe the influence of geometrical variations (dip and width) in the flat of a flat-ramp fault, we made two experimental series, being the first with the flat varying in dip and width and the second maintaining the flat variation in width but horizontal. These experiments developed secondary faults, perpendicular to the extension, that were grouped in three sets: i) antithetic faults with a curvilinear geometry and synthetic faults, with a more rectilinear geometry, both nucleated in the base of sedimentary pile. The normal antithetic faults can rotate, during the extension, presenting a pseudo-inverse kinematics. ii) Faults nucleated at the top of the sedimentary pile. The propagation of these faults is made through coalescence of segments, originating, sometimes, the formation of relay ramps. iii) Reverse faults, are nucleated in the flat-ramp interface. Comparing the two models we verified that the dip of the flat favors a differentiated nucleation of the faults at the two extremities of the mater fault. V These two flat-ramp models also generated an anticline-syncline pair, drag and transversal folds. The anticline was formed above the flat being sub-parallel to the master fault plane, while the syncline was formed in more distal areas of the fault. Due the geometrical variation of these two folds we can define three structural domains. Using the physical experiments as a template, we also made numerical modeling experiments, with flat-ramp faults presenting variation in the flat. Secondary antithetic, synthetic and reverse faults were generated in both models. The numerical modeling formed two folds, and anticline above the flat and a syncline further away of the master fault. The geometric variation of these two folds allowed the definition of three structural domains parallel to the extension. These data reinforce the physical models. The comparisons between natural data of a flat-ramp fault in the Potiguar basin with the data of physical and numerical simulations, showed that, in both cases, the variation of the geometry of the flat produces, variation in the hangingwall geometry

Não é uma tarefa fácil definir requisitos para os sistemas de software que darão suporte a um negócio, dada a dinâmica de mudanças nos processos. O levantamento de requisitos tem sido feito de forma empírica, sem o apoio de métodos sistematizados que garantam o desenvolvimento baseado nos reais objetivos do negócio. A engenharia de software carece de métodos que tornem mais ordenadas e metódicas as etapas de modelagem de negócios e de levantamento de requisitos de um sistema. Neste artigo é apresentada uma metodologia de desenvolvimento de software resultante da incorporação de atividades propostas para modelagem de negócios e levantamento de requisitos, baseadas em uma arquitetura de modelagem de negócios. Essas atividades tornam o desenvolvimento de software mais sistemático e alinhado aos objetivos da organização, e podem ser incorporadas em qualquer metodologia de desenvolvimento baseada no UP (Unified Process - Processo Unificado).

Os objetivos deste estudo foram desenvolver um sistema computacional que efetue o dimensionamento e a evolução de rebanhos bovinos e criar uma ferramenta que possibilite ao usuário efetuar simulações em um sistema de produção de carne e/ou leite. Foi utilizada a linguagem CA Clipper. As rotinas foram desenvolvidas de forma conversacional, com acesso aos diversos programas, por meio de menus auto-explicativos. O sistema desenvolvido pode auxiliar o técnico e o pecuarista no dimensionamento e na evolução de um rebanho bovino com precisão e considerável rapidez; possibilita ao usuário efetuar inúmeras simulações; e constitui -se em importante ferramenta no auxílio da tomada de decisões.

A routine was developed in C++ for the processing of social and environmental census data acquired by the Brazilian Institute of Geography and Statistics (IBGE). The routine employs a simple graphical environment. The data generated are presented in a tabular format, which facilitates a broad and objective view of the values, and provides a convenient means of querying the database. The source code used to develop the routine permits updates and changes, as required by the user. Statistical and mathematical analysis enables the generation of social and environmental indicators, together with quantitative and qualitative classification of the socio-environmental quality of the region analyzed. As an example, the routine was applied using census data for the city of Sorocaba (São Paulo State, Brazil), including conditions of household occupation, water supply, sanitation, level of education, income, and other factors. It is envisaged that the proposed analytical model will assist professionals from different fields of research and teaching to develop urban planning and management strategies.
