Abstract:

This thesis discusses the operational coordination of electrical appliances and devices in a smart home. At present, the diminishing volume of fossil fuels and the increasing pressure to use renewable sources of energy necessitate the integration of such volatile sources into electrical grids. This process, however, results in higher energy costs, and the consumers are thus more willing to change their behaviour to either reduce the expenses or maintain them at a reasonable level. One of the relatively few customer-oriented options to optimise energy costs consists in the demand – response pri

Abstract:

L'accesso ininterrotto all'energia elettrica è diventato il bisogno fondamentale del mondo di oggi. Le parti rurali di molti paesi ancora oggi non hanno accesso all'energia elettrica o hanno accesso a reti di distribuzione deboli con infrastrutture del sistema di trasmissione e distribuzione inadeguate. Tuttavia, nei paesi dove c'è un'abbondanza di risorse rinnovabili come la radiazione solare, la risorsa eolica e corsi d’acqua, l'accesso all'elettricità può essere gestito dalla generazione di energia distribuita. Considerando il fatto che le fonti di energia rinnovabile sono intermittenti in

Abstract:

This thesis presents the project for the optimization of the APOLLO3® neutronic calculation scheme applied to the 4th generation fast neutron reactor ASTRID. APOLLO3® is the new multipurpose neutronic platform developed by the CEA. It incorporates many of the previous generation codes used in the French reactor core design supply chain. Like all deterministic codes, APOLLO3® solves the neutron transport equation with a discretization of the variables of interest: multi-group method for the energy, discrete ordinates and spherical harmonics for the angular variable, collision probabilities and

Abstract:

The future fusion power plants that are based on magnetic confinement will deal with plasmas that inevitably contain energetic (non-thermal) particles. These particles come, for instance, from fusion reactions or from external heating of the plasma. Ensembles of energetic ions can excite eigenmodes in the Alfvén frequency range to such an extent that the resulting wave fields redistribute the energetic ions, and potentially eject them from the plasma. The redistribution of ions may cause a substantial reduction of heating efficiency. Understanding the dynamics of such instabilities is necessar

Abstract:

I camici protettivi in piombo, grazie alle elevate proprietà di assorbimento e di attenuazione delle radiazioni da parte del materiale, sono sempre stati i principali dispositivi di protezione personale utilizzati nel campo della diagnostica radiologica e nelle procedure interventistiche. Nella campo della radioprotezione in Medicina Nucleare invece, è molto vivo il dibattito tra coloro i quali ritengono che l’utilizzo dei DPI, come i camici in gomma al Piombo, non sia particolarmente efficace e quelli che, al contrario, ne suggeriscono l’uso. Obiettivo di questo lavoro di tesi, è stata la va

Abstract:

Un aspetto che riveste notevole importanza nelle fluidodinamica computazione è la simulazione di fluidi con corpi solidi in movimento per sistemi caratterizzati da geometrie complesse e interfacce variabili nel tempo. Un interessante approccio a tali problemi è quello di adottare una formulazione Immersed Boundary che fornisce una rappresentazione mista che combina gli aspetti dei metodi euleriani e lagrangiani. La caratteristica distintiva di tale tecnica è quella di simulare la presenza di ostacoli solidi nel dominio fluido senza utilizzare una griglia conforme, ma impiegando strategie diff
