Proton Exchange Membrane, also named Polymer Electrolyte Membrane fuel cells (PEMFC) are interesting devices for energy conversion. Their development is due to the high efficiency, acceptable power density, quick start-up ...

The present dissertation illustrates the complete procedure of developing a model-based diagnosis algorithm and shows its application to a pre-commercial Solid Oxide Fuel Cell (SOFC) system. The main motivations of this ...

The goal of this thesis is the study of the automotive push-type dry clutches used in the Automatic Manual Transmissions (AMTs) and in the Dual Clutch Transmissions (DCTs) in order to improve their performances dur- ing ...

Negli ultimi venti anni il costo dei carburanti ha subito un notevole aumento con un significativo impatto sui costi del trasporto aeronautico. Inoltre, la Comunità Europea ha lanciato una politica di salvaguardia dell’ambiente ...

Lubricant additives have an important influence on the lubrication performances. These additives are active ingredients which can be added during a blending process to base oils in order either to enhance the existing ...

The laminar-turbulent transition is a complex phenomenon involved in several multidisciplinary design issues, such as skin friction drag reduction, anti-icing and de-icing system performance prediction and heat transfer ...

Every year 5 million of boilers for domestic heating are sold in the European Union (EU). Because heating contributes to more than 20% to the whole energy use in the EU strategies for energy saving are of great interest. Currently ...
