Analysing green supply chain management practices in Brazil's electrical/electronics industry using interpretive structural modelling
(International Journal of Environmental Studies, 2013-06-03) [Artigo]
Industries need to adopt the environmental management concepts in the traditional supply chain management. The green supply chain management (GSCM) is an established concept to ensure environment-friendly activities in ...
Typology of companies networks for competitive assessment: an application in higher education institutions
(Business Management Review, 2014) [Artigo]
Taking into account the changes in the market scenario by virtue of globalization, Institutes of Higher Education (IES) as well as other organizations seek their competitive stability. For that reason, it is up to organizations ...
Use of nonlinear asymmetrical shock absorber to improve comfort on passenger vehicles
(Journal of Sound and Vibration, 2014-03-31) [Artigo]
In this study the behaviour of two different types of shock absorbers, symmetrical (linear) and asymmetrical (nonlinear) is compared for use on passenger vehicles. The analyses use different standard road inputs and include ...
An Experimental Study on the Effect of Temperature on Piezoelectric Sensors for Impedance-Based Structural Health Monitoring
(Sensors, 2014-01-01) [Artigo]
The electromechanical impedance (EMI) technique is considered to be one of the most promising methods for developing structural health monitoring (SHM) systems. This technique is simple to implement and uses small and ...
Tool Condition Monitoring of Single-Point Dresser Using Acoustic Emission and Neural Networks Models
(IEEE Transactions on Instrumentation and Measurement, 2014-03-01) [Artigo]
Identification and online monitoring of the dresser wear are necessary to guarantee a desired wheel surface and improve the effectiveness of grinding process to a satisfactory level. However, tool wear is a complex phenomenon ...
Influence of ideal and non-ideal excitation sources on the dynamics of a nonlinear vibro-impact system
(Journal of Theoretical and Applied Mechanics, 2013-01-01) [Artigo]
The objective of the present work is to analyze the dynamics of a vibro-impact system consisting of two blocks of different mass coupled by a spring with two stages. Two different types of excitation sources for the system ...
Defining functional urban regions in Bahia, Brazil, using roadway coverage and population density variables
(Journal Of Transport Geography, 2014-04-01) [Artigo]
The concept of Functional Urban Regions (FURs), also called Metropolitan Regions (MRs), is not simple. It is clear, though, that they are not simply a combination of adjacent municipalities or areas. Different methods can ...
Distributed harmonic compensation in single-phase low-voltage microgrids
(2018-02-27) [Dissertação de mestrado]
O emprego de switching power interfaces em problemas relacionados a qualidade de energia, tem se tornado uma alternativa interessante na busca de aproveitar ao máximo a contribuição de recursos energéticos distribuídos. ...
Enhanced ferroelectric properties of La-substituted BiFeO3 thin films on LaSrCoO3/Pt/TiO2/SiO2/Si (100) substrates prepared by the soft chemical method
(Ceramics International, 2012-07-01) [Artigo]
Bi0.85La0.15FeO3 (BLFO015) thin films were deposited by the polymeric precursor solution on La0.5Sr0.5CoO3 substrates. For comparison, the films were also deposited on Pt bottom electrode. X-ray diffraction data confirmed ...
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 ...
