Neural approach for automatic identification of induction motor load torque in real-time industrial applications
(2006-12-01)
Induction motors are widely used in several industrial sectors. However, the dimensioning of induction motors is often inaccurate because, in most cases, the load behavior in the shaft is completely unknown. The proposal ...
Using Mininet for emulation and prototyping Software-Defined Networks
(2014-01-01)
Software-Defined Networks (SDNs) represents an innovative approach in the area of computer networks, since they propose a new model to control forwarding and routing data packets that navigate the World Wide Web. Since ...
Development of a filter for phycocyanin bio-optical estimation
(2014-01-01)
Phycocyanin is a unique pigment for cyanobacteria in inland waters which has been identified by remote sensing. Several band ratio algorithms were developed to estimate and identify phycocyanin using its absorption spectral ...
Electrical energy consumption as a function of urban variables
(2008-01-01)
This paper analyzes the electrical energy consumption of households as a function of urban variables, by modelling the urban thermal environment with Artificial Neural Networks (ANN). The study area was a residential ...
Technical and economical analysis of biomass integrated Gasifier/combined heat and power

The actual shortage of fossil fuels has required humanity to employ the rational use of primary energy and as a result new plants in more advanced technological versions have been set up. Technologies of wood gasification ...
Development of platinum-niobium as a CO tolerant catalyst for PEFC operating with CO contaminated hydrogen
(2015-01-01)
This paper presents the results of a bimetallic Pt3Nb/C catalyst prepared by thermal treatment in dilute reductive atmosphere (5% H2 in Ar) to obtain a CO-tolerant catalyst. The thermal treatment leads to the formation of ...
Evaluation of respiratory heat loss by evaporation and convection in ruminants
(2016-01-01)
In order to evaluate heat losses in the respiratory tract through convection and evaporation in livestock the aim of this study was used an equations developed from the tracheal dimensions of ruminants based on the theory ...
Investigating multipath mitigation for kinematic applications using wavelet techniques
(2008-03-20)
Multipath is the phenomenon that occurs when the signal from GNSS satellites reflects on objects surrounding the survey environment and reaches the receiver's antenna through multiple paths. Usually, the receiver collects ...
Recognizing Possibilities of Computational Tinking When Teaching First-degree Equations
