Power quality, smart meters and additional information from different power terms

This paper shows how the detailed examination of active and nonactive power components may produce new information for modern smart meters. For this purpose, a prototype of electronic power meter has been implemented and applied to the evaluation of the Conservative Power Theory (CPT). Considering five sorts of loads, under four different operating conditions, the experimental results indicate that the CPT is able to provide a good methodology for load characterization, which could possibly benefits consumers and power utilities in several different ways. The results also show that depending on the situation, the analysis of nonactive power terms may be more important than the observation of traditional power quality indices, such as total harmonic distortion, unbalance factors or the fundamental positive sequence power factor.

All sol-gel electrochromic smart windows: CeO2-TiO 2/Ormolyte/WO3

A solid state system having the configuration WO 3/Ormolyte/CeO2-TiO2 has been assembled. Syntheses routes for tungsten oxide WO3, and cerium-titanium CeO 2-TiO2 oxide sols, were developed. A novel solid electrolyte - Ormolyte is reported, which were obtained by the sol-gel process, they have a chemical stability due to the covalent bonds between the inorganic and organic phase, and were prepared with different [O]/[L] ratios, being the best for [O]/[L]=15. The variation of transmittance of the electrochromic device using the ormolyte [O]/[L]=15 was 35% (colored state) and 77% (bleached state).

Estrutura de conteúdos educativos para TV Digital: um modelo de referência

This paper proposes a model of educative content structuring for interactive digital television programs. Its intent was to provide references for collaborative production processes and content organization in learning networks associated with university and educative television broadcasting services. The model defines terms, actors, events, environments, as well as content categories, classes and attributes, indicating criteria for their synchronic or asynchronic association in a dynamic television schedule. The model is presented in both descriptive and visual formats, with the use of conceptual maps. The results indicate that interactive use of digital television in education requires systematic content models covering communitarian participation in both media production and distribution processes, in order to enhance learning instruments beyond vertical, hierarchical and centralized communication sustained by traditional broadcast channels.

TV digital interativa e Internet: o caso brasileiro

Em 2003, quando da publicação do decreto nº 4.901, que institui o Sistema Brasileiro de Televisão Digital SBTVD , o panorama vislumbrado era imenso e inspirador: o que despontava era a possibilidade de se ter acesso à internet e todas as vantagens decorrentes dela em cada aparelho de TV do país. Com as discussões sobre qual sistema adotar e posteriormente com as indefinições sobre o middleware, houve tempo suficiente para a internet se afirmar como mídia essencialmente interativa, deixando, por hora, para a TV Digital a qualidade de imagem . O que vemos agora é a qualidade da imagem que alcança em banda larga a tela do computador, seduzindo ainda mais os usuários de TV. Com o Plano Nacional de Banda Larga que visa à popularização da internet de alta velocidade no Brasil, prometido pelo Governo Lula, a TV Digital pode de um lado garantir o canal de retorno necessário para a interatividade plena e, de outro lado, perder uma importante batalha para a internet, que se firmará de vez como mídia interativa.

Face paulista da TV digital: reflexão sobre a multiprogramação na TV cultura

The implantation procedure of the multiprogramming for TV Cultura, a station under the responsibility of the Fundação Padre Anchieta,from the regulation of digital television in Brazil, through the Sistema Brasileiro de Televisão Digital Terrestre (SBTVD-T), involves the creation and implantation of multiprogramming channels of the station, the Univesp TV and the Multicultura channels, which are functioning through means of a special authorization in scientific and experimental character. Analyzed from the Communication Politics Economy point of view, this research contributes to the reflexion about the multiprogramming which may create alternatives to new options in this country programming and content.

Rádio e TV Escola: um projeto de capacitação para leitura e produção midiática na comunidade escolar

The extension project "Rádio e TV Escola: capacitação para o uso de canais de comunicação na comunidade escolar" was created in 2006 to enable the introduction of radio and TV stations into two public schools. Supported by Social Communication’s courses of Universidade Sagrado Coração, the project’s goals were: a) collaborate with teachers in developing student’s literacy in writing and interpreting media texts; b) promote a greater awareness among graduate students of the social responsibility of media.

Ambiente virtual de aprendizagem para TV Digital mediado por recursos educomunicativos

Este artigo apresenta um recorte do processo de desenvolvimento de um modelo de Ambiente Virtual de Aprendizagem de um modelo de Ambiente Virtual de Aprendizagem para Educação a Distância através da NTDIC Televisão Digital, cujo intuito é proporcionar inclusão social e educação através dessa mídia que virá alcançar 98% da população brasileira. Caracteriza-se como um projeto de investigação centrado na inovação tecnológica educacional e na transformação social, que tem como um de seus vetores principais a construção de uma metodologia de Design Educacional contextualizado na elaboração de conteúdos e dinâmicas educativas nas formações à distância, por meio da articulação de recursos de natureza educomunicativa - envolvendo, assim, o campo de interface existente entre as ciências da Educação e Comunicação, já há uma década apontado na academia como um fato.

O mercado da TV digital: cultura, tecnologia e política

This article aims to map the development of the market of digital TV in Brazil, under the aspect of the relation among culture, technology and politics. We start with a history of analog TV, since its inception, showing matrices of Brazilian TV. Then we try to show current conditions of the TV market in the country, its ambiguous relation with the internet and the possible ways for survival of open digital TV: respect for cultural diversity, the observation of the habits acquired from other media, the consistent use of digital language and the modifi cation of public policies in favor of the collective and not protectionism of large private communication companies.

Jornalismo audiovisual: da tela da TV para outras telas

This article is based on research which has been developed in partnership with Unesp TV, a university TV broadcast station of the Universidade Estadual Paulista Julio de Mesquita Filho, Bauru campus/SP. The study aims to identify convergent and divergent aspects in the design of audiovisual journalistic content for TV and other media such as the internet and mobile communication systems. The results presented here are the considerations obtained from the first stage of the research. In this phase, the basic steps which should guide the design of the content to feed broadcasting time are outlined, as well as the online audiovisual news broadcast and business management of a TV station, compared to the model which has been followed by internet TV broadcasters.
