Integrating structural and input design of a 2-DOF high-speed parallel manipulator: A flexible model-based approach
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
This paper discusses the integrated design of parallel manipulators, which exhibit varying dynamics. This characteristic affects the machine stability and performance. The design methodology consists of four main steps: ...
Controle não linear de posição e vibração de manipuladores robóticos com juntas e elos flexíveis utilizando materiais inteligentes
(Universidade Tecnológica Federal do ParanáPonta GrossaPrograma de Pós-Graduação em Engenharia Elétrica, 2015-02-26)
This work presents the modeling and control of robotic manipulators with flexible characteristics, both joints as in the links. The mechanical model is obtained by Lagrangian formulation. Control strategy is considered as ...
Shading effects on community composition and food web structure of a deforested pasture stream: Evidences from a field experiment in Brazil
(Elsevier B.V., 2014-03-01)
Experimental manipulations in the field can evidence cause-effect relations from the manipulated variables. In this context, the aim of the present study was to investigate the effects of shading on stream community ...
Motion of a red blood cell in interference field
(ELSEVIER, 2009)
The motion of a red blood cell suspended in blood plasma in a two-beam plane interference Held was studied experimentally. A cw Argon Ion laser was used. A model is proposed to describe the observed motion. The model is ...
