New approach to four-phase transmission systems: analysis of the transient response and the possible voltage surges

This study describes a technical analysis of a four-phase line as a transmission system alternative. An analysis in the frequency and the time domains is performed to evaluate the electrical characteristics and the transient response of a generic four-phase system compared with those of a conventional three-phase transmission system. The technical features of this non-conventional system are discussed and reviewed based on the current literature. Thus, a new analysis of the four-phase system is presented that emphasises several technical characteristics that have not been discussed in previous studies.

Cidadão em sintonia participativa: uma perspectiva para as Relações Públicas

In contemporary times, to which the media is centralized in the hands of a few, it is necessary to understand and discuss its democratization. In this situation it surges a theory that is still maturing, Communication Public, which reflects the communication by the optic of citizen participation. In this sense, the research has as objective the reflection about democracy, the centrality and conglomeration media in society and what is affecting public broadcast organizations. So has too the intention to defend the performance of professional public relations in this context, due to its humanistic and strategic characteristic. Through literature review, observation of programming of Radio FM UNESP Bauru and interviews with employees, it is perceived that the vehicle radio for its intrinsic characteristics has great potential democratization, when this character in public can promote citizenship. There was also observed the demand for professional public relations, assisting the organization to recognize themselves as a social institution, defining its mission, its goals, its vision and policies, with objective to make two-way symmetrical communication to the public
