A study on the impacts of the 5S program on the productivity of a recycling cooperativeUm estudo sobre os impactos do programa 5S sobre a produtividade de uma cooperativa de reciclagem
(Espacios, 2019-01-01) [Artigo]
Solid waste management is still a challenge for the implementation of the National Solid Waste Policy in Brazil, as it involves setting parameters among stakeholders to feed industries. Waste pickers and recycling cooperatives ...
Influence of grinding on the roundness, residual stresses and microstructure of VC131 steel analysed by varying the type of cutting fluid
(Industrial Diamond Review, 2008-07-16) [Artigo]
This paper by R. E. Catai, E. C. Bianchi, P. R de Águia and M. C. Alves reports on the results of an analysis made of roundness errors, residual stresses, and SEM micrographs of VC131 steel. The analysis involved workpieces ...
Framework for analysis and representation of external systems for online reactive-optimisation studies
(IEE Proceedings: Generation, Transmission and Distribution, 2005-11-01) [Artigo]
The paper proposes a framework for the analysis and representation of external systems for online optimisation studies. The basis for this framework is the equivalent OPF (EOPF), an optimisation model obtained by partitioning ...
Avaliação comparativa de métodos laboratoriais de medição de resistividade elétrica do solo: Uma abordagem teórica
(Solos e Rochas, 2006-09-01) [Nota]
Study on transient ice formation of laminar flow inside externally supercooled rectangular duct
(Applied Thermal Engineering, 2000-12-01) [Artigo]
The transient process of solidification of laminar liquid flow (water) submitted to super-cooling was investigated both theoretically and experimentally. In this study an alternative analytical formulation and numerical ...
Synthesis, structure and magnetic properties of Y3Fe5-xAlxO12 garnets prepared by the soft chemical method
(Processing And Application Of Ceramics, 2014-01-01) [Artigo]
A study was undertaken about the structural, morphological and magnetic properties at room temperature of crystalline aluminium substituted yttrium iron garnet, YIG (Y3Fe5-xAlxO12 with 1.5 < x < 1.7) nanoparticles prepared ...
Unfolding barriers for urban mobility plan in small and medium municipalities – A case study in Brazil
(Transportation Research Part A: Policy and Practice, 2020-02-01) [Artigo]
This paper investigated barriers for the design and implementation of Urban Mobility Plans in small and medium-sized cities in the State of São Paulo, Brazil. To achieve this objective an exploratory survey was carried out ...
An adaptive concurrent two-scale FE model to predicting crack propagation in concrete
(Computational Modelling Of Concrete Structures. Euro-c 2018, 2018-01-01) [Trabalho apresentado em evento]
Finite element analysis including explicitly the details of the heterogeneities (finer-scale) can dramatically increase the numerical effort and memory demand. To minimize these drawbacks, a new concurrent adaptive multiscale ...
Experimental evidence of enhanced ferroelectricity in Ca doped BiFeO3
(Materials Chemistry and Physics, 2014-04-15) [Artigo]
Calcium (Ca)-doped bismuth ferrite (BiFeO3) thin films prepared by using the polymeric precursor method (PPM) were characterized by X-ray diffraction (XRD), field emission gun scanning electron microscopy (FEG-SEM), ...
Hot turning of a difficult-to-machine steel (sae xev-f) aided by infrared radiation
(International Journal Of Advanced Manufacturing Technology, 2014-07-01) [Artigo]
A possible way for increasing the cutting tool life can be achieved by heating the workpiece in order to diminish the shear stress of material and thus decrease the machining forces. In this study, quartz electrical ...
