In this preliminar work, an oscillatory flow contained in a closed cylinder is investigated by means of spectral methods. The problem is quite related with the Stokes boundary layer and the major phenomena belong to this ...

One of the most difficult problems in the RCS prediction of a complex target is the analysis of the cavities existing at the air inlets and outlets of engines. The geometrical complexity of these structures makes difficult ...

[ANGLÈS] Study of the harmonic spectrum on various pulse width modulation strategies for multilevel converters, and how it affects the distortion on the converters.

This paper analyzes the reflected fields produced by parabolic and hyperbolic surfaces when an electromagnetic field falls into them. Multireflector antennas, which are integrated by such reflecting surfaces, are studied ...

[ANGLÈS] The project goal is to design a platform based on an existing HW/SW embeded Linux system containing a FPGA, within an academic environment. To accomplish that objective, a specific application for signal Adquisition ...

We present an algorithm for the unsupervised learning of latent variable models based on the method of moments. We give efficient estimates of the moments for two models that are well known, e.g., in text mining, the ...

Las energías renovables son el futuro, y el estudio de estas todavía está en investigación y desarrollo. Los reactores de fusión pueden dar paso a un nuevo mundo dentro de la energía nuclear, muy diferente del que conocemos ...

This problem discusses here is the hierarchical representation and processing of the hyperspectral imaging. In this framework, Binary Partition Trees (BPTs) are proposed as new hierarchical region-based representation. ...
