Uma arquitetura de nomeação para a internet utilizando redes virtuais
(Universidade Federal de São Carlos, 2007-11-26) Sousa, Joelle Quaini; Guardia, Hélio Crestana; https://lattes.cnpq.br/1780902767520967; https://lattes.cnpq.br/2594257783502353
Regarding new computational and networking requisites such as wireless networks, mutihoming interfaces, load-balancing mechanisms and several other middleboxes [1] present today, these facts, allied to the static and conservative nature of the Internet and its sheer size turn the capability to correct these problems an almost impossible attempt, as it demands structural changes. In the Internet inception, in the late 70th, neither mobility nor multihoming where foreseen in its original intents. In this sense, the proposition of a novel naming architecture for the Internet to identify univocally services and data, irrespective to its node characteristics, would have an acute changing effect and will allow its elements to be precisely represented and authenticated. In order to achieve these purposes, the use of Virtual Networks was considered as it allows the incremental introduction of new technologies, protocols and applications being itself a more viable alternative when compared to several failed attempts to introduce new structural changes to the Internet [2; 3]. A proposal for a taxonomy for Virtual Networks was described here as a result of a site survey that was conducted to function as subject to this architecture proposition. Besides, a literature investigation of related projects followed by a network testbed of several protocols originated the proposition of a Layered Naming Architecture for the Internet using Virtual Networks.
Expansão urbana e formação dos territórios de pobreza em Ribeirão Preto : os bairros surgidos a partir do núcleo colonial Antônio Prado (1887)

This paper is aimed at studying the neighborhoods that originated from the Antônio Prado Colonial Nucleus in the city of Ribeirão Preto in 1887. Meeting the needs of the coffee complex, the colonials occupied the vacant lands still available in the city. The purpose of the colonial nucleus was to supply the population with subsistence goods, attract and set the workforce for the agriculture by means of allotment, but also to modify the profile of the urban inhabitants. Among the demands to acquire a plot of land, the candidate should be a foreigner who had an urban job and also be able to construct his/her won commercial or residential establishment. It was also demanding that the candidate kept an effective cultivation of the land and afforded the maintenance and construction of the improvements in his/her plots of land, under the penalty of losing it in case of breach of the norms established. The two hundred plots that formed the colonial nucleus were immediately occupied and in 1892, after the payment of the debts by most of the previous owners, they were subdivided and got into the market of local lands. At that time, Ribeirão Preto started to testify the development generated by the coffee monoculture, which stimulated the construction of the urban infrastructure, the arrival of the railway, and the installation of a network of services related to the coffee complex. The current urbanism and public health policies, regulated by the "Codes of Conduct", kept away from the population focuses of contamination such as hospitals, cemeteries, industries and slaughterer houses, but it also "protected" the city from "undesirable" people against the maintenance of the new republican elite: poor and sick people, former slaves, immigrants and transgressors. Thus, the area of Antônio Prado Colonial Nucleus corresponded to a deposit of everything that should be "made invisible" regarding human beings and constructions. In face of the segregation imposed by the elites, for whom the immigrants were desirable for work, but not for social relationships, this study showed some of the living strategies of the colonial nucleus inhabitants and the ways by which they modulated an image of themselves and of the city, having the physical space as the definer of the actions. For that, this paper presents the colonials' horticulture production, the development of the jobs, industries, commerce, and the rendering of services, and also religious and associative activities. These were means through which the immigrants could establish more intensely a brotherhood among themselves. After 120 years, as a consequence of the segregation, most of the neighborhoods originated from the former Colonial Nucleus neither grows vertically, nor its plots acquires better prices, although they are located next to downtown.
Análise da percepção das condições da infraestrutura dos pontos de ônibus oferecida aos usuários : um estudo de caso da cidade de São João da Boa Vista, SP
(Universidade Federal de São Carlos, 2007-11-26) Bassi Filho, Raphael; Ferreira, Marcos Antonio Garcia; https://lattes.cnpq.br/2643134259454260; https://lattes.cnpq.br/1957181824022952
This paper is the result from a research which has been done to identify the importance of the expected attributes inside a bus stop design: which are characterized by a system of information and by its framework (furnishings) which may offer to the passengers appropriate conditions during the time that are waiting to board. The variant which distinguish the attributes from the information system and the furnishings elements from the bus stop were selected from a huge amount of variable list through a bibliographic review. The importance of these variants was determined through the information process which has been gotten from the application of a research with the users of this system using the “Professed Priority Technique”. It was noticed that the bus stop features, which were favorite by the users, must offer safe and comfort conditions (seat with shelters), whose furnishings components refer to; and bus stop identification facilities (place identification advertisement) , when it is approached the information system. Subsequently the users prefer that the bus stop environment arranges others facilities (line identification; outline rout, clock, advertising picture and wastebasket). The final result will be able to contribute to a project definition which are bound for a bus stop betterment, giving a better importance to the increase of this kind of transportation demand.
