1. Modelagem de fenômenos intempéricos e erosionais em vertentes : uma aproximação de suas componentes não-lineares com base em métodos de mineração de dados / Modeling of soil weathering on hillslopes : coping with nonlinearity and coupled processes using a data-driven approach
This Doctoral thesis aims to explore the relationship between soil physical-chemical properties and relief morphometry, and quantifying these relationships to build conceptual and predictive models. Self-organizing maps and Geographic Information Systems modeling are here used to investigate nonlinear correlations associated with chemical and physical denuda

2. A CONCEITUAL MODEL FOR ESPECIFICATION FOR SECURITY RISK MANAGEMENT OF INFORMATION SYSTEMS / UM MODELO CONCEITUAL PARA ESPECIFICAÇÃO DA GESTÃO DE RISCOS DE SEGURANÇA EM SISTEMAS DE INFORMAÇÃO
The lack of an alignment among concepts that involve security risk management has caused the stalemate in the adoption of security risks management models for organizations. There are several standards and risk management methodologies, having a large set of concepts, defined in many ways. In order to get an alignment of concepts and establish a suitable voc

3. Modelagem temporal de sistemas : uma abordagem fundamentada em redes de petri / Temporal modeling of information systems: a Petri net based approach
Neste trabalho e proposta a abordagem TempER-Tr, uma técnica de modelagem conceitual, fundamentada em rede de Petri, que integra a especificação das propriedades dinâmicas de um sistema a um modelo de dados temporal do tipo entidade relacionamento. Um modelo ou esquema conceitual descreve as propriedades identificadas de um sistema a ser desenvolvido. Es

4. Gerenciamento de serviços e governança de TI. Modelagem de um processo de gerenciamento de configuração
Information technology (IT) is becoming essential for organizations. In this context, IT management has evolved to include service management and IT governance, towards business driven IT management paradigms. Thus, the alignment between IT and business has been regarded as one of the leading factors for the effectiveness of such paradigms. Furthermore, cont

5. MODELOS CONCEITUAIS PARA PROVENIÊNCIA / PROVENANCE CONCEPTUAL MODELS
Information systems, developed for several economic segments, increasingly demand data traceability functionality. To endow information systems with such capacity, we depend on data provenance modeling. Provenance enables legal compliance, experiment validation, and quality control, among others . Provenance also helps identifying participants (determinants

9. Sistemas de información: nuevos escenarios basados en ontologías
While ontology is still a fertile area of research in the field of Philosophy, Ontologies currently stands for research, development, and application fields in disciplines related with computing, information and knowledge. Information Systems (IS) are essentially knowledge artifacts that capture and represent knowledge in certain domains. Considering that on

10. Um modelo de hipertexto para apoio ao ensino mediado pela Web / A hypertext model to support Web-mediated teaching
There is an increasing demand for hypermedia applications based on the WWW (World Wide Web), known as Web Information Systems (WIS). These applications present specific requirements in addition to those of traditional software systems, thus fostering the need for investigating suitable models to support their development. In particular, systems for Distance

12. Architecture for explicit knowledge management on product development processes / Arquitetura para gerenciamento de conhecimentos explícitos sobre o processo de desenvolvimento de produto
The product development is characterized by a continuing design-build-test cycle, marked by experimentation and the intensive use of enterprise knowledge. Part of them is tangible and is stored in the documents created during the product development process, named explicit knowledge. This work analyzes the computational solutions for support the explicit kno
