Arcabouço para aprovisionamento de QoS e QoE em redes sem fio heterogêneas WiMAX/Wi-Fi com garantia de equidade entre vazões

Recently, the society is living amid an agglomerate of mobile devices with multiple wireless interfaces that allow mobile customers home and business solve routine problems in the shortest time and in several locations. On the other hand, the availability of various wireless access technologies such as Wireless Fidelity (Wi-Fi), Worldwide Interoperability for Microwave Access (WiMAX) and Long Term Evolution (LTE), provide a heterogeneous scenario with several connectivity opportunities for the user of devices with multiple interfaces. Some of the current challenges in framing the so called Next Generation Networks (NGN) are the development of frameworks and mechanisms that enable both adequate support for Quality of Service (QoS) and Quality of Experience (QoE) for multimedia applications, and assurance equity among throughputs of different applications in a heterogeneous environment. This dissertation proposes a framework for provisioning of QoS and QoE in heterogeneous wireless networks consisting of WiMAX and Wi-Fi networks. Specifically, our solution provides static mapping of QoS between classes of service WiMAX and access categories Wi-Fi. In addition, our proposal also combines features of equity among throughputs with the mapping solution in order to achieve a good tradeoff for both, for the network operator and for the user, through a new methodology for collection and calculation of aggregate throughput and algorithm for Vertical Handover Decision (VHD). The quantitative evaluation of the proposal was carried out using simulation models in Network Simulator (NS-2). The performance results demonstrate the efficiency of the framework in terms of QoS (throughput, average throughput and delay) and QoE (Peak Signal to Noise Ratio, Structural Similarity Index and Video Quality Metric) metrics.

Artistas indígenas: processos de inclusão no cenário artístico roraimense
(Universidade Federal do Pará, 2015-06) PAIVA, Anderson dos Santos; FAVRETO, Cristiane Bade
This article deals with the promotion of indigenous art and culture in the State of Roraima highlighting the role of the Federal University of Roraima (UFRR) in order to disseminate and raise awareness about the importance of multi-ethnic aspect in the construction of local identity. We present the current situation and confront the main issues regarding the construction of space for indigenous arts as well as barriers and obstacles to the full development of practical artistic representations of the various ethnic groups in Roraima. Therefore, we rediscutimos some concepts about the relationship between art and anthropology and the strengthening process of discursive design of these artists to emphasize the appreciation of cultural diversity of the state.

Da anistia à redemocratização: o processo de esquecimento da 5ª Companhia de Guardas
(Universidade Federal do Pará, 2023-07-10) COSTA, Carolina Silva da; PETIT, Pere; http://lattes.cnpq.br/8376409779394321; https://orcid.org/0000-0002-8970-3073
When talking about the dictatorship of 1964-1985, one goes back to a sensitive past, laden with memories and traumas that persist in power struggles, installed in the democratic process in Brazil since Law nº 314/1967 on National Security, passing through Law 6,683/1979 from Amnesty to the current historic buildings. Understanding and knowing the speeches and characters whose past lived is a study developed by researchers of the history of the present time, as well as problematizing the memory that permeates through subjective and also physical fields - the museums - places of memories brought by Nora (1988). Those spaces whose purpose is to remember, however, when they create a gap of forgetfulness, it becomes paradoxical, making it necessary to provoke historiographical constructions with regard to the dictatorial period. In this way, the methodology with bibliographical analysis was used in articles, books and productions, which cited the 5th Company of Guards as a place of prison, today Museum of Contemporary, Modern Art and photos, or House of Eleven Windows, located in the neighborhood of Cidade Old woman in Belém–PA. Museum that makes up one of the formative spaces of Happy Lusitânia, the set of heritage revitalized and resignified within the project that aims to publicize the first contacts of the European colonizer and the natives. House of Eleven Windows, in its chronological functions, served as the home of Domingos Bacelar, then as a Military Hospital and a space for the collection of testimonies and incarcerations of subversives in the 20th century, the 5th Company of Guards and finally the Museum. However, the point of discussion of this research is that in its current curatorial proposal, its repressive past is not disclosed, leaving the visitor out of tune with the real history contained in general, since not even all passivity passed on actually occurred in this space. Therefore, gathering in this research a historiographical base of names identified as subversive, in their actions within the resistance and that were sent to provide clarifications in the 5th Company of Guards, is the objective of this research, with the intention of provoking the sensitive memory in opposition to the speeches implanted by the silence and oblivion built in the building.
