Land parceling and neighborhood impacts in Brazil
(Journal of Urban and Environmental Engineering, 2009-12-01) [Artigo]
The proposal and implementation of parceling real estate into smaller lots in Brazil is done according to legal and technical formalities. However, these instruments have proved inefficient in reducing the resulting ...
Control of instabilities in non-Newtonian free surface fluid flows
(Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2013-10-01) [Artigo]
Free surface flows in inclined channels can develop periodic instabilities that are propagated downstream as shock waves with well-defined wavelengths and amplitudes. Such disturbances are called roll waves and are common ...
Closure to energy efficiency for standard penetration tests by Edgar Odebrecht, Fernando Schnaid, Marcelo Maia Rocha, and George de Paula Bernardes
(Journal of Geotechnical and Geoenvironmental Engineering, 2007-04-01) [Editorial]
Characteristics of the double-torsion test to determine the R-curve of ceramic materials
(Materials Research, 2006-10-01) [Artigo]
Double-torsion tests were carried out on a commercial ceramic floor tile to verify whether this test is suitable for determining the R-curve of ceramics. The instantaneous crack length was obtained by means of compliance ...
Solid mass falling into the reservoirs shallow water equations validity from the engineering point of view
(Revista de la Facultad de Ingenieria, 1998-12-01) [Artigo]
Water waves generated by a solid mass is a complex phenomenon discussed in this paper by numerical and experimental approaches. A model based on shallow water equations with shocks (Saint Venant) has developed. It can ...

To compare the removal efficiency of solids, turbidity and apparent color between a conventional and a column settling tanks in a recirculating aquaculture system (RAS) for tilapia farming. Materials and methods. Tilapia ...
NUMERICAL SIMULATION of THE BEHAVIOR of THE BEHAVIOR of REINFORCED CONCRETE BEAMS and COLUMNS BY FEM CAASTEM 2000 PROGRAM
(Revista Internacional de Metodos Numericos para Calculo y Diseno en Ingenieria, 2009-01-01) [Artigo]
The objective of this paper is the numerical study of the behavior of reinforced concrete beams and columns by non-linear numerical simulations. The numerical analysis is based on the finite element method implemented in ...
A BEM formulation based on Reissner's theory to perform simple bending analysis of plates reinforced by rectangular beams
(Computational Mechanics, 2008-10-01) [Artigo]
In this work, the plate bending formulation of the boundary element method (BEM), based on the Reissner's hypothesis, is extended to the analysis of plates reinforced by rectangular beams. This composed structure is modelled ...
