Uma estratégia para otimizar a geração de arranjos em subestações virtuais de energia elétrica

The Virtual Reality techniques applied in Electricity Environments provide a new supervisory control paradigm. The fact of existing a virtual environment (VE), geometrically similar to a real substation, reduces the difference of mental models built by field operators compared with those built by system center operation improving the communication. Beside this, those systems can be used as visualization interfaces for electricity system simulators, training systems for professors and undergraduate students, field operators and maintenance professionals. However, the development process of these systems is quite complex, combining several activities such as implementation, 3D modeling, virtual sceneries construction, usability assessment and management project techniques. In this context, this work present a GUI strategy to build field arrangements based on scene graphs, to reduce time in Virtual Electricity Substations Arrangement development. Through this, mistakes during the VE building can be avoided making this process more reliable. As an concept proof, all toolkits developed in this work were applied in the virtualization of the substations from a Brazilian power concessionary named CEMIG.

Luz-personagem: o jogo de manipulação da iluminação cênica em cenas cômicas

This research has as a central point of discussion the relationship between the action and the stage lighting, directed to scenes in which, from the exchange between actor and professional lighting, you can develop comic situations. The particularity of these scenes is the involvement of lighting as presentification feature a character in the scene, made possible by game created with the actor. In order to develop this discussion, the author divides the text into three chapters, the first being a memorial of his artistic career and his creative processes, enabling the reader to situate the paths taken by the author for the study. Then discusses possible relationship between performance and lighting, pointing situations where the two are directly related. Finally, an analysis and comparison of two comic scenes in which the actor play with the lighting suggests a character through presentification lighting on the scene. Leads the discussion to the conclusion, proposing the term light-character to set the lighting feature, suggesting characters in the scene.
