37. Cibersegurança em sistemas de automação em plantas de tratamento de água. / Cibersecurity in automation systems in water treatment plants.
Currently, information security is a constant concern of the several institutions and countries that use computing resources for communication and service offering purposes. Protection methods and countermeasures for traditional networks such as firewalls and intrusion detectors are known and ordinarily used. The same goes for control systems and data acquis

39. A FAULT TOLERANT MECHANISM FOR WORKFLOW MANAGEMENT SYSTEMS / UM MECANISMO DE TOLERÂNCIA A FALHAS PARA SISTEMA DE GERENCIAMENTO DE WORKFLOW
In this work we propose a mechanism for failure detection, group management and service replication, providing fault tolerance for workflow management systems. Workflow management systems require specific replication features, since such systems deal with non-deterministic operations and update their s internal state without any external calls. As a case stu

44. The Capital Goods Market and the combination of generic strategies / O mercado de bens de capital e a combinação das estratégias genéricas
This study deals about the topic of the generic strategies disseminated by Porter, which has been topic of researches as much in the academic world as used in the business world due to its extension and easiness of comprehension. The generic strategies are cost leadership, leadership in product differentiation and focus. Porter inferred that a company must c

45. Decision support method to apply Additive Manufacturing Technologies for plastic components in the aircraft industry
Additive Manufacturing Technologies (AMT) are a collection of manufacturing processes driven by CAD data to produce physical models and parts by means of additive techniques. They are based on a layer-by-layer material consolidation process instead of the traditional methods. Due to machine and material developments, such processes may be used to produce fin
