Item type: Item , Caracterização de funções de realidade aumentada usando computação de borda(Universidade Federal de Goiás, 2025-06-02) Rodrigues, Karlla Bianca Chaves; Cardoso, Kleber Vieira; http://lattes.cnpq.br/0268732896111424; Corrêa, Sand Luz; http://lattes.cnpq.br/3386409577930822; Correa, Sand Luz; http://lattes.cnpq.br/3386409577930822; Both, Cristiano Bonato; http://lattes.cnpq.br/2658002010026792; Berretta, Luciana de Oliveira; http://lattes.cnpq.br/0987947348533817The growing use of immersive applications—such as augmented reality, virtual reality, and mixed reality—has led to increasing demand for more efficient computational resources capable of real-time data processing. While cloud computing can meet these demands, it often introduces high latency, negatively affecting the user experience. Edge computing emerges as a promising alternative by bringing computational resources closer to enduser devices, reducing latency, enhancing immersion, and enabling the deployment of such applications on mobile devices. Understanding the functional components of these applications and their performance profiles is essential for efficient offloading between mobile devices and edge servers. This work aims to characterize two core tasks in mobile augmented reality applications: Simultaneous Localization and Mapping (SLAM) and object detection. To this end, the MR-Leo prototype was used, integrating ORB-SLAM2 and incorporating a new object detection functionality based on the YOLO architecture. The research evaluates the performance of these tasks under different hardware configurations, considering execution on both CPUs and GPUs. The results show that although SLAM is computationally intensive, it performs acceptably on CPU-based architectures. In contrast, object detection requires massive parallelism for satisfactory performance and is heavily dependent on GPU usage. Based on the task characterization, a statistical workload model was developed to support the creation of workload generators capable of emulating the behavior of augmented reality applications under different computational architectures and scenarios.Item type: Item , Desenvolvimento de bebida fermentada de tangerina murcott (citrus reticulata)(Universidade Federal de Goiás, 2025-07-30) Silva Filho, Josinaldo Florêncio da; Asquieri, Eduardo Ramirez; http://lattes.cnpq.br/0488056148950480; Asquieri, Eduardo Ramirez; http://lattes.cnpq.br/0488056148950480; Briceno, Julio Cesar Colivet; Oliveira, Tatianne Ferreira De; http://lattes.cnpq.br/2017895913160804ResumoItem type: Item , Despejos na Pandemia: Estratégias de Resistência das Ocupações na Região Metropolitana de Goiânia(Universidade Federal de Goiás, 2025-09-29) Veiga, Isabela Caixeta; Rezende, Wagner de Souza; http://lattes.cnpq.br/6091908383087318; Hora, Karla Emmanuela Ribeiro; http://lattes.cnpq.br/6451685640638572; Sanches, Débora; http://lattes.cnpq.br/2074241895208327; Rezende, Wagner De Souza; http://lattes.cnpq.br/6091908383087318The COVID-19 pandemic (2020-2022) contributed to the deepening of existing social problems in Brazil, exacerbated primarily by the neoliberal transformations and the mismanagement of coronavirus control policies. In this context, many solidarity initiatives emerged, primarily targeting those most socially vulnerable. These actions were coordinated by entities, institutions, associations, organizations, and social movements that formed support networks. One of these networks gave rise to the Zero Evictions Campaign (CDZ), a national mobilization to end evictions, which intensified during the health crisis. Therefore, this research aims to answer how urban occupations in the Goiânia Metropolitan Region (RMG) organized themselves to overcome or mitigate eviction during the COVID-19 pandemic. The main objective was to identify resistance strategies in the face of imminent evictions and worsening social vulnerability during such a critical period. To this end, this research used a multiple case study methodology for two urban occupations located in the municipality of Aparecida de Goiânia. Multiple methods were used to collect information: bibliographic and documentary research, spatial analysis through photographs and maps, interviews, and participant observation. Grounded theory will be used for analysis. The urban occupations in the RMG resisted through a process of self-organization, which was strengthened by mobilization in the CDZ and organization into a social movement, the Workers' Movement for Rights (MTD). Thus, this research aims to contribute to the discussion on citizenship, insurgency, and the fight for the right to the city, considering that the pandemic situation has driven new forms of mobilization and organization for social struggles.Item type: Item , O ensino de ciências da natureza no contexto da pandemia da covid-19: O que revelam as publicações na área(Universidade Federal de Goiás, 2025-09-25) Veridiano, Thiago dos Santos; Echalar, Jhonny David; http://lattes.cnpq.br/5746522784363534; Echalar, Jhonny David; http://lattes.cnpq.br/5746522784363534; Oliveira, Natalia Carvalhaes De; http://lattes.cnpq.br/7560948180074168; Pinheiro, Regiane Machado De Sousa; http://lattes.cnpq.br/4039400420451350This research addresses the teaching of natural sciences in the context of the COVID-19 pandemic that began in 2020. The suspension of in-person classes and the adoption of Emergency Remote Education (ERE) revealed structural and pedagogical weaknesses in Brazilian education, especially in public schools. The scenario of social isolation, coupled with socioeconomic inequalities, highlighted the limitations of access to digital technologies, the overload of teaching work, and the learning difficulties of students. Given these conditions, it became essential to understand: what are the implications of Emergency Remote Education (ERE) on teaching strategies for Natural Sciences during the covid-19 pandemic? Morevoer, it was necessary to highlight the challenge of maintaining pedagogical ties and promoting meaningful learning in the midst of the crisis. The research was conducted using a qualitative, exploratory approach based on a systematic literature review and document analysis. The corpus consisted of 15 articles published between 2020 and 2024 in journals qualified by CAPES (strata A1 to A4) that address the teaching of Natural Sciences during the pandemic. Content analysis based on Bardin (1977) allowed for the construction of “units of analysis” that organized the data around pedagogical strategies, which were analyzed in light of Historical-Critical Pedagogy (HCP). From this perspective, it was found that the teaching of Natural Sciences during the ERE approached the empiricist conception of science more significantly, and in terms of the pedagogical perspective, it was found that most teaching practices did not approach Historical-Critical Pedagogy (HCP). Although this was the theoretical framework of the present research and was debated as a possibility for overcoming decontextualized and technical practices, the data analyzed show the predominance of a technical and transmissive approach, marked by strategies focused on the presentation of content and the application of tasks, often without articulation with the social reality of the students. Few experiences proposed a critical mediation of scientific knowledge, as proposed by HCP. The experience of teaching Natural Sciences during the pandemic revealed both weaknesses and opportunities. While, on the one hand, it deepened educational inequalities and exposed gaps in technological infrastructure, on the other, it opened paths for the more systematic incorporation of digital technologies, for the strengthening of student autonomy, and for the development of more critical and contextualized pedagogical practices. The legacy of this period points to the urgency of public policies that ensure digital inclusion, continuing teacher training, and the effective integration of technologies in teaching, in order to consolidate advances and address the contraditos still present in the educational process.Item type: Item , Análise geoespacial do processo erosivo hídrico linear no estado de Goiás e Distrito Federal(Universidade Federal de Goiás, 2020-04-30) Rodrigues, Hellbia Samara Moreira de Carvalho; Castro, Selma Simões de; http://lattes.cnpq.br/4460827622247417; Luiz, Gislaine Cristina; http://lattes.cnpq.br/4310433384519387; Silva, Elaine Barbosa da; http://lattes.cnpq.br/0056241036193048; Castro, Selma Simões de; http://lattes.cnpq.br/4460827622247417; Silva, Laura Fernanda Simões da; http://lattes.cnpq.br/2235270776321472; Kertzman, Fernando FacciolaThe intense conversion of the Cerrado into agricultural and livestock areas resulting from the expansion of the agricultural frontier, especially since the second half of the last century, led to the incorporation of their lands into the national productive system, based on an agroexport model anchored in commodities, especially associated with the binomial meat and grains. Despite being economically successful, this process caused a reduction of its continuous area by about 50% and several environmental impacts, such as deforestation and occupation of sensitive areas accompanied by the development of water erosion processes. Such processes, in the form of ravines and gullies, especially medium and large, have been extensively studied in the Southwest of Goiás, where factors favorable to their development dominate. However, there was no study of the preferential distribution of the existing erosive foci, nor of the conditions and their susceptibilities on the state scale. The present thesis started from the hypothesis that the linear water erosion process results from favorable conditioning factors related to the physical and biotic environment, which gives them greater susceptibility, and also to the discrepancy in land use and management. The objective of the thesis is to analyze the preferential distribution of linear erosive foci in the state of Goiás and its interrelationships with the components of the physical and biotic environment, in order to identify the critical areas and the respective attributes that indicate the process. The methodological strategy was based on a decreasing geospatial multi-scalar approach accompanied by physical-based geocartography, starting with the inventory and mapping of erosive outbreaks (focus) with the aid of remote sensing and geoprocessing, using Geographic Information System (GIS). It´s proceeded with the elaboration of the isodensity map of the outbreaks that allowed the identification of Critical Areas, with a greater density of outbreaks. Next, two areas of the most critical ones were selected, which were analyzed in detail regarding the morphopedological compartmentalization, the erosive susceptibility and its relationship with the distribution of the erosive outbreaks and the conditioning factors of the physical and biotic environment, in order to identify the main causes of the process. The results revealed 5 Critical Areas in the State, the largest being in the Southwest region, in which the predominance of outbreaks is located in the morphopedological compartments supported by sandy soils with high erodibility, in flat to smooth undulating reliefs, with high water erosion susceptibility and predominant use with pastures, although without discrepancy in use. It is concluded that the management of susceptible areas is not adequate and is the main responsible for the erosive occurrence in the most critical areas.
