Reliability studies in the Brazilian pre-salt oil production environment have shown promise, as seen in surveys carried out between 2017 and 2023 on the platforms MaintWorld, Machinery and Equipment MRO, Science Direct, Google Academic and CAPES, mainly for the determination of frequency of occurrence of failure events, obsolescence of data and their behavior over time is one of the concerns in the context of current engineering. This dissertation discusses a survey of equipment rel...
Focus on renewable energy, as well as energy generating systems efficiency, has grown with the increasing planet´s energy demand and the predicted limitation on energy resources over the years. A good viable alternative to more efficient and clean energy production, given the environmental concerns, is utilizing a polygeneration system integrating multiple forms of energy storage and production combined. The studies on polygeneration grow as the years go by and hospital units have p...
Project management understands complex processes that involve a variety of material and human resources and multidisciplinary activities. The research takes place through a case study carried out in a capital-intensive company, aiming to identify deadline deviations, and to understand the relationship between the application of best practices and assertiveness in the implementation. This work proposes the interaction between processes and management methods for project implementatio...
Virtual reality (VR) experiences are frequently developed using game en gines, which are difficult for unskilled professionals who lack programming and 3D modeling skills. Concurrently, there is a knowledge gap in software project design for intuitive VR authoring tools, which were intended to be more user-friendly. Frequently, these authoring tools are inadequate due to a lack of standardized operating procedures. This study contributes to the development of more intuitive VR authoring ...
Transformations on a global scale, driven by technological development, have been demanding a new profile of engineer. In addition to technical knowledge, it is necessary to train professionals with transferable skills such as leadership, teamwork, communication, creativity, among others, to develop sustainable engineering products, processes and systems. In this context, Higher Education Institutions (HEI) must provide the development and assessment of these competencies. Recent re...
With the increasing number of protein sequencing data, the first step in identifying this macromolecule is to compare proteins to identify their similarities with known proteins. This similarity analysis can identify evolutionary relationships between the compared spe cies. Similar sequences imply species that share a recent common ancestor. However, the sequences are not always conserved in evolution, so in this case, a comparison with the more conserved structure can be an alternative t...
In recent years, bacterial cellulose (BC) has been the object of much research due to its high potential for application in areas such as biomedicine or materials, as well as because its biosynthesis is environmentally friendly. The BC is characterized as a homopolymer and is differentiated from vegetable cellulose by its properties, highlighting mainly the biocompatibility and biodegradability of the materials produced. The production of BC composites with various polymers is an effe...
The use of renewable energy sources is a big step for the future of a nation, especially Brazil has been highlighted by the large availability of solar energy throughout its territory. However, the presence of clouds and aerosols in the atmosphere can compromise the use of this type of energy in the electrical system, predicting associated meteorological variables a challenging task. In this sense, in view of a sustainable model of energy generation and recent advances in the area o...
Arising from the combination of tailored chemical composition and thermomechanical processing, advanced high strength steels (AHSS) provide an important balance between mechanical strength and weight reduction desired in automobiles. In this context, 22MnB5 steel stands out for offering mechanical strength levels around 1500 MPa in the hot-stamped condition, after quenching. Joining of components in the automotive industry, usually achieved by the resistance spot welding (RSW) proce...
