En este estudio se comparan los respiradores convencionales (mascarillas desechables) de tela no tejida frente a otros tipos de tela tejida como el tafetán, con el fin de determinar la eficacia del tejido en condiciones ...

El presente trabajo explora la influencia de las propiedades electrostáticas, concretamente el potencial zeta, en las capacidades de filtración de diversos materiales. Reconociendo una laguna en la bibliografía existente, ...

El següent projecte consisteix en la gestió i disseny d’un equip filtrador d’oli vegetal, que sigui capaç de filtrar l’oli domèstic varies vegades, fent-lo apte per a un futura utilització. El dispositiu també planteja un ...

Image segmentation is defined as a partition realized to an image into homogeneous regions to modify it into something that is more meaningful and softer to examine. Although several segmentation approaches have been ...

The main objective of this study is to evaluate qualitatively and quantitatively the effect of starvation periods in the biodegradation capacity of microorganisms when the support media is a material with high sorption ...

The least-squares estimation problem with non-minimum-norm constraints on the unknown model parameters is considered. Contrary to the quadratic-constraint least-squares solutions the approach presented does not necessarily ...

Biofiltration has been established as a promising alternative to conventional air pollution control technologies. However, gas biofilters modeling has been less developed than experimental research due to the complexity ...

Cepstral coefficients are widely used in speech recognition. In this paper, we claim that they are not the best way of representing the spectral envelope, at least for some usual speech recognition systems. In fact, cepstrum ...

Data from the regular monitoring of a full-scale biofilter at a municipal solid waste treatment facility for the integral treatment of domestic residues was analyzed in order to assess potential operational problems and ...
