Il project management e l'importanza dell'analisi stakeholder nel risk management: il caso del piano di messa in servizio dei contatori smart meter 2g in megareti
Get PDFPresentazione dell'analisi integrata degli stakeholder di progetto e dei rischi attraverso l'applicazione pratica dello strumento Stakeholder Shape
Analisi e ottimizzazione dei flussi dei materiali e delle informazioni nei reparti di montaggio. Il caso Drtech/Enter
Get PDFL'elaborato riporta l'esperienza di tirocinio effettuata nelle ditte Enter Srl e DrTech. Il progetto di tirocinio è stato incentrato sull'ottimizzazione dei flussi dei materiali e delle informazioni all'interno delle due aziende, focalizzandosi sui loro reparti di montaggio. Al fine di perseguire tali obiettivi sono state utilizzate sia tecniche tradizionali di gestione a scorta delle giacenze, sia pratiche lean come kanban, visual management e VSM
CFD Modeling and Analysis of a Boundary Layer Ingesting S-shaped Intake
Get PDFExamination and evaluation of the performance of the boundary layer ingesting S-duct intake in a conventional aircraft fitted with an aft-fan engine through a parametric study conducted with CFD simulation. The analysis concerns the investigation of the design process of a S-duct and the exploration of the main flow features upstream the intake and through it. Different shapes of the lip, throat heights and CR are discussed for several intake designs varying the mass flow ratio
Analisi LCA di una turbina eolica ad asse orizzontale
Get PDFIl lavoro di tesi verte sull'analisi del ciclo di vita della tubina FX EVO 16-20, di proprietà dell'azienda ESPE Srl. L'analisi è stata svolta tramite l'utilizzo del software SimaPro; si sono analizzati due siti, Candela in provincia di Foggia e Monte d'Aria in provincia di Macerata, confrontandone poi i risultati ottenuti
PA 12 composites with Graphite and MWCNT produced by SLS, Injection Moulding and Compression Moulding: Performance analysis
Get PDFThis study focused on the study of the influence of graphite and carbon nanotubes (CNTs) in a polymer matrix composite (PMC), in which polyamide 12 (PA12) was used as a matrix, producing samples with three different technologies, namely SLS, IM and CM. The results of this research showed a real influence of graphite and CNTs on the final properties, although the electrical and thermal conductivity has undergone little improvement, not allowing to obtain sufficiently conductive materials

Get PDFMotion control of water droplets by means of optical patterns imprinted on Fe:LiNbO3 crystals
Get PDFChemical and morphological surface patterning is very common in micro
uidic devices
to control the
ow. In this project, the dynamics of water droplets moving
on a iron-doped lithium niobate (Fe:LiNbO3) crystal which has been exposed to
optical patterns produced by lenses will be studied. This optowetting technique will
exploit the photovoltaic eect of lithium niobate, that creates surface charges upon
illumination and enables the control of droplets without xed electrodes. To reduce
the friction, the crystal surfaces will be covered with a micrometric lubricant lm
(LIS) made of octadecyltrichlorosilane (OTS) impregnated with silicone oil that acts
as hydrophobic dielectric layer. The behaviour of the LIS will be investigated by
droplet sliding on glass and Fe:LiNbO3 substrates and compared with results from
literature. The interaction between charged regions at the Fe:LiNbO3 surface and
water will be proved by analyzing pendant droplets falling on the substrates due
to the dielectrophoretic force. In the nal experiments, the motion of drops with
dierent volumes on straight lines with dierent inclinations imprinted on samples
tilted at dierent angles will be observed by means of video recordings
