    Dust exhaustion systems in the aluminum industry – reference data and design methodology definition problems
    (INSTITUTO DE TECNOLOGIA, 2007) TREJO, Antonio Mauricio Martelli; VASCONCELLOS, Mauro Fernandes; MESQUITA, André Luiz Amarante.; MAGALHÃES, Edilson Marques
    The study addresses challenges in designing dust exhaustion systems for the aluminum industry, emphasizing the lack of reference data for specific equipment and process emissions. Methodologies for calculating air flow and pressure drop in exhaust systems are reviewed, with a focus on pneumatic conveying of particulates. The work proposes an improved methodological approach based on hydrodynamic models and presents real-world case studies, such as coke loading/unloading systems and alumina feeding in potlines. Conclusions include recommendations for optimizing system performance.

    Reciclagem do resíduo da estação de tratamento de efluentes da indústria de injeção de plástico na indústria de cerâmica vermelha
    (INSTITUTO DE TECNOLOGIA, 2009) JIMENEZ, I. J.; SOUZA, J. A. S; BRITO, F. S. de.; Eduardo de Magalhães Braga
    The study investigates the feasibility of recycling waste from plastic injection industry effluent treatment stations by incorporating it into red ceramic production. Mixtures with 2%, 5%, and 10% waste relative to clay were evaluated, analyzing properties such as density, porosity, and flexural strength. The results indicate that the waste positively influences solid-state reactions, enhancing some mechanical properties of ceramic products, especially at concentrations up to 5%. The research presents a sustainable alternative for industrial waste disposal, aligned with environmental demands.

    Aspectos Importantes na Utilização de Bombas Centrífugas em Velocidade Variável para a Redução do Consumo de Energia
    (Instituto de Tecnologia, 2006) MESQUITA, André L. Amarante; SILVA, Lázaro J. S. da; ABRAHAM JÚNIOR, Otávio; PEREIRA, José Almir; R. SILVA, Aldo Cezar P.; BATISTA, Clauderino da Silva
    The study examines the use of variable speed centrifugal pumps as a solution to reduce energy consumption in water supply systems. It covers theoretical principles, technological aspects, and economic feasibility, employing frequency inverters to adjust flow according to demand. Two case studies illustrate the method's effectiveness: parallel pump operation and tank level control. Results show significant energy savings with short financial payback, emphasizing the need for technical and economic analysis for implementation.

    Protocolo Híbrido para Autenticação Quântica de Mensagens Clássicas com uso do Gerador de Sequências Pseudo-aleatórias Blum-Blum-Shub
    (Universidade Federal do Pará, 2006) AZEVEDO, Manoel Socorro Santos; ASSIS, Francisco Marcos de; FREIRE, Raimundo Carlos S.
    In the present time, when the search for computational and unconditional security is a reality, studies have been done to solve problems related to messages changes and authentication, in a safe way. Cryptographic systems are studied, valued and tested for real safety, allowing the cryptoanalysis of such systems. The quantum cryptography appears as a powerful allied to provide unconditional security. The quantum authentication of classic messages is a reality that can be put in practice in a relatively short time. A hybrid protocol authentication of classic messages is considered, using the BBS (Blum-Blum-Shub), pseudo-random sequence generator. The protocol´s security against individual attacks is formally evaluated.

    A Importância da Convergência Tecnológica nas Áreas de Telecomunicações como Ferramenta Estratégica ao Desenvolvimento Regional: Uma Visão dos Stakeholders
    (Universidade Federal de Santa Catarina (UFSC), 2001) LEITE, Jandecy Cabral; ROSSETTO, Carlos Ricardo
    The study addresses the importance of technological convergence in the telecommunications area as a strategic tool for the sustainable development of the Amazon State, from the stakeholders' perspective. The research demonstrates that, despite the geographical and communication challenges of the region, technological convergence can contribute to the conservation of natural resources and the well-being of the population. The work explores the relationship between globalization, sustainable development, and technological advancement, highlighting the need for policies and strategies that integrate these areas for regional development.
