Influence of ABS print parameters on a 3D open-source, self-replicable printer
(2020-01-01)
Purpose: The purpose of this paper is to investigate and discuss the influence of printing parameters on the mechanical properties of acrylonitrile butadiene styrene (ABS) print by fused deposition modelling (FDM). The ...
Optimization of the mechanical properties of low-carbon steels by formation of a multiphase microstructure
(2001-12-01)
In this work five methods of heat treatments are investigated in order to obtained convenient volume fractions of ferrite, bainite, martensite and retained austenite, starting with a low carbon steel and seeking the ...

A new computational tool for the follow up of mechanized excavation of tunnels: the case study of the subway line 5-LILAC in São Paulo, Brazil
(Fundação Gorceix, 2018-12-01)
Abstract The management and monitoring of mechanized tunnel excavation parameters are crucial for ensuring the safety, quality and project's time/costs, since these parameters are the only existing elements that enable the ...
Study of Brazilian commercial Oriented Strand Board panels using stress wave
(2013-08-09)
Today lumber industry has shown a clearly evident trend towards wood based panels' production; and, among them, Oriented Strand Board (OSB) has become more and more prominent. Nondestructive Testing (NDT) such as stress ...

About the crossing of the energy levels of a parameter-dependent quantum-mechanical Hamiltonian
(Springer, 2015-09)
The purpose of this letter is to correct the lack of generality of one of the statements put forward in a recent article about the noncrossing rule in quantum mechanics. We illustrate the point by means of an exactly ...
