(2019-07-08)The research presented in this dissertation treats the subject of efficient gear contact simulation and is applied to the contact analysis of spiral bevel gears. In today’s competitive environment getting better products ... -
<<An>> investigation on the usability of the Kinect by Microsoft in upper limb rehabilitation after stroke
(2016-12-15)L’Ictus rappresenta la seconda causa di disabilità in Europa e la sesta nel mondo. Il danneggiamento del tessuto nervoso, a seguito di Ictus, può portare ad una perdita della mobilità dell’arto superiore, limitando così ... -
Analisi Energetica di sistemi ibridi con celle a combustibile: modello di simulazione numerica di un sistema SOFC/TG alimentato con miscele ricche di idrogeno
(2014-10-28)Nell'ambito della tecnologia a celle a combustibile ad alta temperatura, nel presente lavoro di tesi è stato formalizzato un modello matematico per la simulazione di un Sistema Ibrido SOFC/GT. E' stato delineato uno ... -
Analysis of mechanical properties of cold spray coatings for tribological and vacuum applications
(Università della Calabria, 2020-07-13)Cold Gas Dynamic Spray (CGDS) is a process in which solid particle are accelerated in a de Laval nozzle toward a substrate. At the impact, if the particle velocity exceeds a critical value, i.e. the critical velocity, ... -
