Traffic demand in wireless communication systems has emerged as a key issue over recent decades. An ever-increasing trend is projected for the next few years, with explosive data traffic expected to materialize and mobile users imposing new quality of service requirements. This growing demand, combined increasingly complex heterogeneous network (HetNet) scenarios, presented ever more challenges operators terms service, coverage, load balancing, service. Considering traditional association...
The fight against corruption in public institutions, particularly universities and federal institutes, requires efficient tools for auditing monitoring administrative processes. This paper presents a tool designed to analyze cases by identifying key elements within these processes, such as classification, damage, motivation, while observing recurring patterns. leverages Natural Language Processing (NLP) techniques Large Models (LLMs) automate the extraction analysis of relevant information....
The Araguaia-Tocantins basin, essential for riverine communities due to its importance in artisanal fishing, faces a substantial lack of information, preventing the formulation effective policies. Although Fishery Statistics System (SIEPE) exists as traditional information system, proposed integration with Artificial Intelligence (AI) platforms allows natural language queries that are converted into Structured Query Language (SQL) commands, thereby increasing accessibility available data....
This study presents an approach based on Reinforcement Learning (RL) to optimize the orchestration of User Association and Resource Allocation (UARA) mechanisms in next-generation heterogeneous networks, focusing maximizing user satisfaction. The proposed strategy aims improve efficiency these networks by overcoming operational challenges through user-centered adaptive algorithms. RL algorithms are utilized rebalance network load distribution radio resources among Equipments (UEs),...
Expanding broadband services represents a significant challenge for operators, especially in light of the requirements related to total cost ownership these technologies. In last few years, this expansion has advanced significantly, but it still that must be overcome since there is need provide low-cost rural communities remote areas. Issues geographical location, low income residents, and lack public infrastructural facilities lead disadvantageous relationship between potential revenue...
The modern society are daily becoming more internet connected. Such connection requires an unprecedented amount of energy to operate each piece equipment that is part the heterogeneous networks (HetNets). network infrastructure highly energy-consuming and producing a considerable CO2. One strategy minimize such consumption making usage renewable energy, as solar wind. This article aims present study technical, economic environmental feasibility for installation photovoltaic harvesting...
The use of renewable sources as an energy matrix has become crucial for the development rural mobile networks both to meet increasing consumption in network segments and improve efficiency grid. Thus, this work aims analyze economic viability photovoltaic system source 5G environments by means models cost installation operation systems. Results indicate that although analysis is characterized a scenario with low population density, where due geographic location access difficulties, great...
Este trabalho apresenta a aplicação de um modelo Monitoramento Adaptativo da Pesca em conjunto com técnicas clusterização dados mistos relativos à registros atividade pesqueira na bacia Araguaia-Tocantins entre 2016 e 2017. Os dos desembarques pesqueiros foram obtidos por meio do Sistema Integrado Estatística Pesqueira (SIEPE), que se como uma proposta ferramenta capaz dinamizar o processo coleta análise das bacias pesqueiras Região Amazônica. Por interface exploração SIEPE diversas...
Após a validação do Decreto Federal nº 10.977, de 23 fevereiro 2022, que define o Serviço Identificação Cidadão (Serviço Cidadão) para alterar Lei nº. 7.116/83 substitui atual Sistema Nacional Registro Civil, no qual os Cartões Geral (RGs) são numerados com base Cadastro Pessoa Física e expedidos critérios emissão uniformes todo território brasileiro, é extrema importância estados adaptem seus sistemas à nova norma até março 2023. Para isso, sistema já implantado deve ser adaptado garantir...
Context: In the current context, digital presence has become essential for businesses, especially micro and small facing challenges in migrating to cyberspace understanding social media data.

Proposed Solution: The paper presents concept of Systemic Avatar SM Analyzer tool, collects real-time data from your networks automatically generates a unique persona representative set people who...
Many organizations are still not fully leveraging internal marketing and gamification strategies, often due to a lack of effective tools for implementation. This can result in significant disengagement among employees decrease productivity. Based on this issue, proposed platform aims act as support tool organizations, providing necessary functionalities effectively implement strategies marketing. It may assist achieving better results their goals objectives.
O estudo sobre a pesca na Média Bacia Araguaia-Tocantins investigou 18 comunidades pesqueiras em 7 municípios do Pará, analisando os rios Tocantins, Araguaia e Itacaiúnas. A pesquisa buscou compreender atividade pesqueira nessas regiões, destacando importância da sustentabilidade gestão participativa. Os dados foram coletados analisados por meio auto monitoramento pesca, revelando diferenças produtivas entre territórios estudados. resultados apontam para necessidade de considerar fatores...

Os resultados obtidos demonstraram que BERTimbau alcançou acurácias entre 88% 90% nos testes...
Due to the limited computing resources of drones, it is difficult handle computation-intensive tasks locally, hence, fog-based computation offloading has been widely adopted. The effectiveness an operation, however, determined by its ability infer where execution code/data represents less computational effort for drone, so that, deciding offload correctly, device benefits. Thus, this paper proposes MonDroneFog, a novel architecture that supports image offloading, as well monitoring and...
Este trabalho apresenta um modelo de Monitoramento Adaptativo da Pesca que foi avaliado pelo método clusterização dados pesca coletados em 2016-2017 na bacia Araguaia-Tocantins.
