[EN] Surge is a phenomenon that limits the operating range of the compressor at low engine speeds and high boost pressure in turbocharged powertrains. This article assesses two prototype turbochargers of variable geometry ...

[EN] This paper presents a spreadsheet application for data filtering and energy analysis, which has applications in research and experimental evaluation of the energetic performance of alternative refrigerants. ...

Heterogeneous nuclear reactors require numerical methods to solve the neutron diffusion equation (NDE) to obtain the neutron flux distribution inside them, by discretizing the heterogeneous geometry in a set of homogeneous ...

Variable order affine projection algorithms have been recently presented to be used when not only the convergence speed of the algorithm has to be adjusted but also its computational cost and its final residual error. These ...

[ES] Se elaboró un modelo semiempirico de una celda individual de combustible tipo PEM en estado estacionario. En primer lugar, se construyó un modelo mecanístico de la celda de combustible, con 7 parámetros. El valor ...
