Utilização do protocolo anycast em ambientes virtuais distribuídos visando à escalabilidade do sistema

Distributed Virtual Environments (DVE) allow multiple users interact with a virtual world by sharing, manipulating objects. Each user has his/her own vision of this world and every changes of state of the environment are distributed among other users. Due to technological constraints, most systems for distributed virtual environments support a limited number of users. The major limitation for development of DVE scale are imposed by the communication system. As the number of users grows, the amount of bandwidth required to exchange information in real time among stations to upgrade the environment and keep it in a consistent state for all connected users. Based on this situation is proposed a framework that uses the protocol anycast in the application layer that provides a load balancing among servers in the region and aims at reducing the latency of message delivery between participants selecting the DVE server best suited for the region participant to connect to the environment

Relações públicas e serviços virtuais: a comunicação entre as corporações da internet e o cibernauta

The objective of this study is to adress the action possibilities of the Public Relations professional in management of communication between the virtual services companies and their customers – the cybernauts. For this purpose, a bibliographical research was made about the cyberspace, Internet environment, as well as the cyberculture and the on-line consumer public. It was also studied the possible areas of Public Relations's action, their work tools and means of communication with the customer, in order to verify the specificities of communication mediated by new technologies. Based on these concepts, it was possible to propose an action of this professional in the organizations called dotcom, in order to contribute to the management of the communication flow between companies and this “invisible” public, which relates virtually to the organization, establishing different modes of interaction in relation to tradicional customers, requiring different strategies of relashionsip

We visited and analyzed the museums: Museum of Energy Rio Claro - Mill Park Corumbataí, Catavento Culture and Education - Social Organization of Culture, Centre for Scientific and Cultural (CDCC) and Studies Center of the Universe - CEU. Point out elements of these museums that benefit the formal teaching of physics in schools, as well as positive elements of schooling that maximize the experience of museum visits

O aprimoramento de um software de estúdio virtual por meio de técnicas de matting digital e registro de objetos virtuais

A virtual studio system can use technologies as augmented reality and digital matting to decrease production costs at the same time it provides the same resources of a conventional studio. With this, it’s possible for the current studios, with low cost and using conventional devices, to create productions with greater image quality and effects. Some difficulties are recurrent in virtual studio applications that use augmented reality and digital matting. The virtual objects registration in augmented reality techniques suffer from problems caused by optical distortions in the camera, errors in the marker tracking system, lack of calibration on the equipments or on the environment (lighting, for example), or even by delays in the virtual objects display. On the other hand, the digital matting’s main problem is the real-time execution to preview the scene, which must have optimized processing speed at the same time while maintain the best image quality possible. Taking the given context into consideration, this work aims to give continuity to a virtual studio system called ARStudio, by enhancing digital matting, virtual objects registration and introducing a segmentation based on depth map, yet adding better control over functionalities previously implemented

Estudo das representações do mundo do trabalho de alunos do meio rural através do uso de mídias virtuais

This paper aims to present the representations of the working world of high school students, the State School Prof. Dr. João Deoclécio da Silva Ramos, Distrito de Talhado, São José do Rio Preto (SP), through the use of virtual media, specifically the Blog de Aula – Mutirão de Sociologia (www.mutiraodesociologia.com.br). Understanding the representations of the world work enables students to think of a profession which identify themselves, and stimulate reflection as future professionals. The virtual media, especially blogs, allow students to express their ways of living and thinking the world of work. In the context of the city of Rio Preto, is especially relevant these representations of the world’s rural work, so this project is to collaborate in the development of research concerned with the description and understanding of processes that involve relationships between work, education and rural.

Formação Reflexiva do Professor em Contextos Virtuais: A Experiência do Projeto Teletandem Brasil

This article chiefly aims at discussing issues concerning reflective teacher education for and in virtual environments for language learning. Given the need for research on reflective practice in new virtual environments, we present the experience of pedagogical supervision through mediation in the virtual context for collaborative learning in teletandem. Some research results in this context, such as in Salomão (2008), Kfouri-Kaneoya (2008), Cândido (2010) and Silva (2010), show how favorable and conducive to the development of reflective pre-service teacher education it seems to be, as it emphasizes the co-construction of knowledge in a dynamic relationship between theory and practice.

Museus ferroviários do Estado de Sao Paulo (Brasil): as políticas de conservação e o estado atual do patrimônio ferroviário brasileiro

This paper is to discuss the expansion and partly dismantlement of Brazilian merchant marine, tracking their legal, administrative and planning. The analysis period extends from the formation of the Comissão da Marinha Mercante, 1941, to the end of the government of Fernando Henrique Cardoso, 2002. In this long duration it is discussed the formation of the national system of economy and the dynamics of contradictory national merchant navy. The text is divided into two parts: 1) Expansion: The centralization, the planning and nationalization with the formation of the shipbuilding industry, highlighting the actions of the Comissão da Marinha Mercante and the Superintendência Nacional da Marinha Mercante, planning and financing the national navigation; 2) Demolition part: the denationalization and privatization of the national navigation, in addition to the deep restructuring of the shipbuilding industry, highlighting the creation of the Agência Nacional de Transporte Aquaviários during the last years of Fernando Henrique Cardoso government.

Design de Relações entre tecnologias amigáveis e sociabilidades virtuais: um novo campo de investigação para o Design

The Digital Age, with its new interactive and converging technologies, stimulates original forms of sociability, which are interconnected, intercommunicating and virtualized through hyperscreens. Another kind of interaction arises from the digitization and new speeds of contemporary communicative process. With the new order of knowledge, it is now possible to transgress the limits of physical space and linear time sequence, through the collective development of content through such telematics networks. Youth gives voice to a new type of user, or a social actor, whose thinking is connected to other communication habits, consolidating singular cultural standards, demanding new languages and skills. Here, we address the nature of this Design of new relations, interactions, behaviors and social systems that emerge in the so called Information Society.

Representatividade das redes sociais no processo educacional: potencialidades dos grupos virtuais como ferramentas de ensino-aprendizagem no Ensino Médio

One tool that has been in evidence, especially among young people, is Facebook. It can be classified as a synchronous communication tool that allows communities of people with similar interests to discuss and exchange experiences in real time, promoting the sharing of information and the creation of collective knowledge, even if they being in different parts of the globe. In this paper we show that Facebook can be used as an educational tool to aid the work done in the classroom and the impact of creating closed groups in online social networking for educational purposes. The survey was conducted with a group of students at a private school in Bauru/SP. We investigated the interaction profile of students with a closed group created on Facebook and through a questionnaire analyzed whether students use virtual environments for personal or educational. The survey reveals students perceptions about relevant aspects and the potential use of this tool as teaching-learning strategy
