13. Controle de vibração de um sistema sob desbalanceamento rotativo utilizando atuador de liga com memória de forma / VIBRATION CONTROL OF A SYSTEM UNDER UNBALANCED ROTATING USING SHAPE MEMORY ALLOY ACTUATOR
The vibration control is an important field of study within mechanical engineering, whose main objective is to reduce and control the vibration of a system. There are various techniques and methods for vibration control, and among them are those using dynamic vibration absorbers In this context, Shape Memory Alloys (SMA) can be used as actuators that help th

14. Integrating mixed-reality remote experiments into virtual learning environments using interchangeable components
This paper presents a proposal to integrate mixedreality remote experiments into virtual learning environments (VLEs) using the concept of interchangeable components, which can represent either real or virtual devices or software in industrial automation systems. Combinations of real and virtual technical plants and automation systems are used in different l

15. SIMOO-RT : an object-oriented framework for the development of real-time industrial automation systems
This paper presents SIMOO-RT, an object-oriented framework designed to support the whole development cycle of real-time industrial automation systems. It is based on the concept of distributed active objects, which are autonomous execution entities that have their own thread of control, and that interact with each other by means of remote methods invocation.

17. Estudo da cinética e do equilíbrio da adsorção da cefamicina C em resina de troca iônica e simulação do processo contínuo
The cephamycin C (CefC) is a beta-lactam antibiotic produced from submerged and aerated cultures of Streptomyces clavuligerus. Acts as inhibitor of cell wall formation of Gram-negative bacteria and is resistant to the hydrolytic action of betalactamases enzymes. The literature presents few scientific results published regarding the purification of CefC, and

19. Avaliação da influência dos parâmetros do processo de soldagem TIG sobre a qualidade de uma peça fabricada em aço elétrico silicioso / Influence of TIG welding process parameters on the quality of a piece fabricated with silicon electrical steel
The TIG welding process (Tungsten Inert Gas), also known as GTAW (Gas Tungsten ArcWelding), is the most commonly used process for welding of thin plates where there is a need for an excellent control of the temperature applied on the piece. This paper presents a study carried out in partnership between the Department of Graduate Studies in Scienceand Materia

20. Estudo experimental da combustão molhada na recuperação de oleo pesado / Experimental study of the wet combustion on heavy oil recovery
One way to improve the performance of the oil recovery method, known as dry forward in situ combustion, is to inject water either simultaneously or intermittently with the air, named as wet forward in situ combustion. The specific heat of the dry air is considerably lower than that of water, such that water may render a better transport of the heat generated

22. Sistema de irrigação por capilaridade na produção de porta-enxertos de mudas citricas na fase de sementeira / Irrigation system by capillary action in the citrus rootstocks production in seedings stage
The water and nutrition management in the production of citrus rootstocks in the seedling phase performed by sprinkler systems, manually operated, presents the environmental outcome of water or residual solution disposal from the fertigation. The generated wastewater is generally discarded directly in the soil with the risk to reach the groundwater and conta

23. Reliability prediction for structures under cyclic loads and recurring inspections
Abstract: This work presents a methodology for determining the reliability of fracture control plans for structures subjected to cyclic loads. It considers the variability of the parameters involved in the problem, such as initial flaw and crack growth curve. The probability of detection (POD) curve of the field non-destructive inspection method and the cond

24. Assembly and evaluation of a cooling tower for use in teaching undergraduate activities / Montagem e avaliação de uma torre de resfriamento para uso em atividades de ensino de graduação
This work describes proposal for complementing Process Systems Engineering (PSE) undergraduate learning. Traditional teaching of PSE is normally restricted to modeling and computer simulations, with very little contact with actual processes. We felt that applying theoretical concepts to practical problems would be very welcome by the students and improve the
