Behavior of the PMD coefficient of optical links under influence of mechanical and thermal effects
(2004-12-01)
This papers presents results on the variation of the PMD coefficient of optical links under influence of mechanical tests, such as tensile strength, bending and compression, and also during the application of a thermal ...
Method for estimating railroad track settlements due to dynamic traffic loads
(2005-12-01)
This paper is the result of real-scale physical modeling study designed to simulate the load-deformation characteristics of railroad foundation systems that include the railroad ties, the ballast, and the sub-base layers ...
Straightforward systematic approach for fuel efficiency and emissions assessment in automotive systems
(2011-12-01)
At this time, each major automotive market bares its own standards and test procedures to regulate the vehicle green house gases emissions and, thus, fuel consumption. Hence, much are the ways to evaluate the overall ...
A multiaxial fatigue damage model for isotropic materials
(2020-01-01)
This paper presents a novel damage mechanics based failure model enabling the prediction of low cycle fatigue life and residual strength of isotropic structures under multiaxial loading. The approach herein proposed does ...
Electropolymerization mechanism in aqueous solution of the oxo-manganese complex biomimicking of the enzymatic center present on the photosystem II
(2012-12-01)
The [Mn4 IVO5(terpy)4(H 2O)2]6+ complex, show great potential for electrode modification by electropolymerization using cyclic voltammetry. The electropolymerization mechanism was based on the electronic transfer between ...
Geotechnical and structural behavior of the railroad track in large-scale apparatus
(2009-12-01)
This paper analyses the static and dynamic behavior of the railroad track model in laboratory. Measurements of stresses and strains on a large-scale railroad track apparatus were studied. The model includes: compacted soil, ...
Using multiple abstraction levels to speedup an MPSoC virtual platform simulator
(2011-07-28)
Virtual platforms are of paramount importance for design space exploration and their usage in early software development and verification is crucial. In particular, enabling accurate and fast simulation is specially useful, ...
Compressive fatigue in titanium dental implants submitted to fluoride ions action
(2007-07-01)
The aim of this study was to assess the influence of a fluoridated medium on the mechanical properties of an internal hexagon implant-abutment set, by means of compression, mechanical cycling and metallographic characterization ...
Mechanical Measurements Of Two Exogenous Surfactants Using A Langmuir Film Balance:A Comparative Study
(Philadelphia, 2013)
Rationale: The primary function of surfactant is to reduce the surface tension at air-liquid interface. In this study, the surface tension behavior of two commercial surfactants, poractant alfa (ChiesiFarmaceuticals,ltaly) ...
Economic and technical feasibility study of a combined-cycle cogeneration system associated with cellulose plants
(1992-12-01)
In this paper, is presented an economical and technical feasibility study of a combined cycle cogeneration system proposed to be used in a pulp plant located in Brazil, where around 95% of country's pulp production is done ...
