Análise dinâmica de rotores em balanço utilizando procedimentos computacionais e experimentais
(Universidade Federal de Minas GeraisUFMG, 2008-04-25)
This work deals with a study of the dynamic behavior of overhung rotors running below the first critical speed, which are supported by roller bearings. A special case of overhung rotor, which consists of an industrial ...
Variable structure controller and observer applied to induction machine
(IEEE, 1998-01-01)
This work will propose the control of an induction machine in field coordinates with imposed stator current based on theory of variable structure control and sliding mode. We describe the model of an induction machine in ...

Cyclo-nonstationary analysis for bearing fault identification based on instantaneous angular speed estimation
(Manizales - Ingeniería y Arquitectura - Doctorado en Ingeniería - AutomáticaDepartamento de Ingeniería Eléctrica y ElectrónicaUniversidad Nacional de Colombia - Sede Manizales, 2019)
Rolling Element Bearings (REB) are present in most of the rotating machines in charge of supporting the shaft's load. For such a reason, REB are prone to fail. REB failures under real conditions such as variable speed/load ...
Evaluación de la afectación de la capacidad vial dado a la implementación de medidas de traffic calming. Caso de estudio: cámaras de detección electrónica de la ciudad de Barranquilla
(Corporación Universidad de la CostaIngeniería Civil, 2020)
Comparative thermal ecophysiology in Pristidactylus scapulatus populations from the Puna region of Argentina
(Elsevier Gmbh, 2021-04)
Reptiles are important models for understanding fundamental aspects of physiological ecology and for assessing how environmental change can impact biodiversity. Abiotic factors (micro-environmental temperatures, operative ...
Diseño e implementación de un estimador de estados híbrido como respaldo para un sistema Scada en una planta de tratamiento de agua residual
(Universidad Santo TomásPregrado Ingeniería ElectrónicaFacultad de Ingeniería Electrónica, 2022-08-08)
In this project, hybrid state space models and finite automaton were used for the design and simulation of a hybrid state estimator, which has been proposed as support for the electronic instrumentation system designed by ...
Acionamento vetorial de motores de indução trifásicos com enfraque-cimento de campo e maximização do conjugado por ampère
(Universidade Federal de UberlândiaBRPrograma de Pós-graduação em Engenharia ElétricaEngenhariasUFU, 2016)
Modelagem da difusão intrapartícula para predição da cinética da esterificação catalítica heterogênea de ácido acético e isopropanol empregando Nb2O5
(Universidade Federal de Santa MariaBrasilEngenharia QuímicaUFSMPrograma de Pós-Graduação em Engenharia QuímicaCentro de Tecnologia, 2020-09-29)
The esterification reaction is one of the most important processes of organic synthesis in liquid phase, since esters have many applications in the chemical industry. Isopropyl acetate, for example, is used as a solvent ...
