Design of an automatic impedance matching system for industrial continuous microwave ovens. Part I: Modeling and off line tuning (Trabalho apresentado em evento)
(2003)The impedance matching is an essential part of a microwave heating system in order to avoid reflections and optimize the operations of the generator. In some applications the load under heating has its impedance variable ... -
Drying of beans in a pulsed fluid bed dryer: Drying kinetics, fluid-dynamic study and comparisons with conventional fluidization (Artigo de Periódico)
(2007)Fresh carioca beans (Phaseolus vulgaris) were submitted to convective drying in a pulsed fluidized bed (PFB) dryer. A full factorial design was developed in order to analyze the effects of the following process variables ... -
An extended instrument variable approach for nonparametric LPV model identification (Trabalho apresentado em evento)
(Elsevier B.V., 2018)Linear parameter varying models (LPV) have proven to be effective to describe non–linearities and time–varying behaviors. In this work, a new non-parametric estimation algorithm for state-space LPV models based on support ... -
Fluidized ASBR treating synthetic wastewater: Effect of recirculation velocity (Artigo de Periódico)
(Elsevier, 2008)An investigation has been performed on the effect of liquid phase recirculation velocity and increasing influent concentration on the stability and efficiency of an anaerobic sequencing batch reactor (ASBR) containing ... -
A grey-box identification approach for a human alertness model (Trabalho apresentado em evento)
(Institute of Electrical and Electronics Engineers Inc., 2019)Many notorious disasters in the last few decades may have been correlated with fatigue or human error. Detecting the level of fatigue from a person, in order to monitor and predict possible risk situations, has become a ... -
Hard turning of tempered DIN 100Cr6 steel with coated and no coated CBN inserts (Artigo de Periódico)
