13. Uma metodologia para caracterização do tráfego de redes de computadores: uma aplicação em detecção de anomalias / Methodology for traffic characterization of computer networks: an application in anomaly detection
The methods of intrusion detection based on anomalies model the default behavior of network traffic and identify anomalies as deviations from the behavior model mapped. The modeling of traffic behavior requires the analysis of large datasets to extract knowledge about the particularities of each network environment, considering the services provided, number

16. Simulação do escoamento monofásico em um estágio de uma bomba centrífuga utilizando técnicas de fluidodinâmica computacional
Oil production and exploration techniques have evolved in the last decades in order to increase fluid flows and optimize how the required equipment are used. The base functioning of Electric Submersible Pumping (ESP) lift method is the use of an electric downhole motor to move a centrifugal pump and transport the fluids to the surface. The Electric Submersib

22. WARPING-BASED METHODOLOGY TO CORRECT DISTORTION IN ENDOSCOPY SYSTEMS / METODOLOGIA BASEADA EM WARPING PARA CORREÇÃO DE DISTORÇÕES EM SISTEMAS DE ENDOSCOPIA
Images captured in endoscopy examinations show some distortion, the radial is the most visible. The radial distortion appears in images due to lens used in endoscopes. When a doctor or researcher is analyzing a distorted image, he can not see the exact size of an organ, tumor or lesion, due the magnification in the center of the image and a contraction in th
