In this work, studies of two-dimensional transient heat diffusion problems in domains of rectangular and elliptical geometries, submitted to boundary conditions of first kind, were carried out. For the problem formulation, ...

Plant transformation is a widely used procedure for obtaining transgenic plants and to develop plant models to understand gene function. Plant models such as Nicotiana tabacum are widely used for understanding gene responses ...

This work present a study of glulam beams reinforced with FRP. It was developed a theoretical model that calculates strength and stiffness of the beams. The model allows for the calculation of the bending moment, the ...

We present a 3D numerical modeling of an ONAN distribution transformer. We found that the 3D problem of natural convection in this thermohidraulic device can be studied by a numerical model that represents a 3D slice of ...

The Geodesy methods and equipments progress brings with himself the growing need on geodetic surveys. Thereby, it is possible to make compatible any surveys with no extension boundary like from plane models and with no ...
