Felix, Jorge Luis Palacios; Balthazar, Jose Manoel [UNESP]; Rocha, Rodrigo Tumolin; Tusset, Angelo Marcelo; Janzen, Frederic ConradMade available in DSpace on 2018-12-11T17:37:47Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-10-01; This paper demonstrates that vibration mitigation and energy harvesting can be achieved simultaneously by using of an electricity-generating from autoparametric vibration absorber system (AVAS) and non-ideal system (NIS). The NIS consists of a simple portal frame excited by a small dc motor with eccentr...
Using saturation phenomenon to improve energy harvesting in a portal frame plat...
Rocha, Rodrigo Tumolin [UNESP]; Balthazar, Jose Manoel [UNESP]; Tusset, Angelo Marcelo; Piccirillo, Vinicius; Felix, Jorge Luis PalaciosMade available in DSpace on 2018-12-11T17:29:46Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-01-01; A new model of energy harvester based on a simple portal frame structure subjected to saturation phenomenon is presented. Energy is collected via a piezoelectric device whose nonlinearities are considered in the mathematical model. The system is a bistable Duffing oscillator presenting chaotic behaviour...

Felix, Jorge Luis Palacios; Balthazar, José Manoel [UNESP]; Tusset, Ângelo Marcelo; Piccirillo, Vinícius; Bueno, Atila Madureira [UNESP]Made available in DSpace on 2018-12-11T17:26:30Z (GMT). No. of bitstreams: 0 Previous issue date: 2015-01-01; In this paper a robotic arm is modelled by a double pendulum excited in its base by a DC motor of limited power via crank mechanism and elastic connector. In the mathematical model, a chaotic motion was identified for a wide range of parameters. Controlling of the chaotic behaviour of the system were im...
The technology application in the teaching learning of Differential Calculus
Scremin, Gisele; Quartieri, Marli Teresinha; Oliveira, Eniz Conceição; Felix, Jorge Luis PalaciosThis paper presents the experience report of the technology used in the teaching-learning of the concepts of differential calculus. The graphic display of the software Desmos was explored in a Calculus I class of fifteen students of the Agronomy Degree in an Institution of Higher Education of Rio Grande do Sul, with the goal to verify the contributions of Desmos to the teaching of derivatives of the first and s...
