Prática pedagógica desenvolvida em uma turma de quinto ano do ensino fundamental na perspectiva da matriz de referência de matemática
(Universidade Federal de Santa MariaBrasilUFSMCentro de Ciências Naturais e Exatas, 2013-12-05)
This study describes a pedagogical practice made with students from the fifth year in primary school related to mathematical investigation. It has been proposed due to some descriptors’ approaches presented in the group ...
Line based camera calibration in machine vision dynamic applications
(1999-12-01)
The problem of dynamic camera calibration considering moving objects in close range environments using straight lines as references is addressed. A mathematical model for the correspondence of a straight line in the object ...
Predictive Current Control With Instantaneous Reactive Power Minimization for a Four-Leg Indirect Matrix Converter
(2017)
This paper presents the experimental validation of a predictive current control strategy with minimization of the instantaneous reactive input power for a Four-Leg Indirect Matrix Converter (4Leg-IMC). The topology includes ...
Grapevine tissues and phenology differentially affect soluble carbohydrates determination by capillary electrophoresis
(Elsevier France-editions Scientifiques Medicales Elsevier, 2017-09)
Soluble carbohydrates distribution depends on plant physiology and, among other important factors, determines fruit yield and quality. In plant biology, the analysis of sugars is useful for many purposes, including metabolic ...
A LMI BASED CONTROL OF A THREE PHASE VOLTAGE SOURCE INVERTER CAPABLE TO OPERATE IN ISLANDED AND GRID CONNECTED MODES
(Ieee, 2015-01-01)
This paper introduces a strategy to control a three phase voltage source inverter used in distributed generation in microgrids scenario. In this context, the inverter should operate in grid connected and islanded modes. ...

A Note on the Prior Distributions of Weibull Parameters for the Reliability Function
(Taylor & Francis Inc, 2009-01-01)
In Bayesian Inference it is often desirable to have a posterior density reflecting mainly the information from sample data. To achieve this purpose it is important to employ prior densities which add little information to ...
