    Second life batteries of electric vehicles : analysis of use and management models 

    Rallo Tolós, Héctor (Data de defensa: 2021-02-09)

    The mobility of the future undoubtedly involves the electrification of vehicles. The increase in social awareness towards a reduction in CO2 emissions, together with the introduction of new laws regulating them, has finally ...

    Solving the nearest rotation matrix problem in three and four dimensions with applications in robotics 

    Sarabandi, Soheil (Data de defensa: 2021-04-27)

    Since the map from quaternions to rotation matrices is a 2-to-1 covering map, this map cannot be smoothly inverted. As a consequence, it is sometimes erroneously assumed that all inversions should necessarily contain ...

    Specific energy consumption of metal cutting with thin abrasive discs 

    Awan, Muhammad Rizwan (Data de defensa: 2021-11-02)

    The aim of this research is to provide an in-depth understanding of energy consumption in abrasive disc cutting processes. The specific energy consumed in cutting is measured,analysed, and then characterised in to three ...

    Study and characterisation of surface integrity modification after ultrasonic vibration-assisted ball burnishing 

    Jerez Mesa, Ramón (Data de defensa: 2018-03-02)

    This dissertation is an experimental research project into the mechanical effects of the ultrasonic vibration-assisted ball burnishing process on the surface integrity of surfaces machined through ball-end milling. Due to ...

    Study and characterization of mechanical properties of wood-PLA composite (Timberfill) material parts built through fused filament fabrication 

    Zandi, Mohammad Damous (Data de defensa: 2020-07-17)

    This research is based upon the additive manufacturing (AM) technology which aims to study the mechanical properties of innovative commercial wood-PLA composite material (Timberfill) and characterize its behavior. Specifically ...

    Study of the beam induced vacuum effects in the cryogenic beam vacuum chamber of the Future Circular Hadron Collider 

    Bellafont Peralta, Ignasi (Data de defensa: 2021-01-25)

    The Future Circular Hadron Collider (FCC-hh) is a proposal for a 100 km long hadron collider conceived as the successor of the Large Hadron Collider (LHC). The FCC-hh is designed to reach 50 TeV of beam energy, greatly ...

    Study of the characterization of the mechanical properties of materials with elastomeric behavior for biomedical applications 

    Adrover Monserrat, Bàrbara (Data de defensa: 2023-02-24)

    (English) The mechanical characterization of new materials used in the Material Extrusion technique (MEX) in 3D printing is essential. The use of this technique is growing and with it the possible applications of printed ...

    Tool-part tribological interaction assessment for continuous deformation processes 

    Torres Chamorro, Lisbeth Alejandra (Data de defensa: 2023-07-03)

    (English This dissertation is an experimental assessment of the tool-part tribological interaction of continuous deformation processes: ball burnishing as a superfinishing process and wire drawing as a bulk deformation ...

    Ús de l'oli vegetal cru com a biocarburant per autoconsum agrícola: avaluacio de la sostenibilitat del sistema a Catalunya 

    Baquero Armans, Grau (Data de defensa: 2011-07-06)

    La introducció de la colza en la rotació de conreus i la producció i ús d’oli vegetal cru (OVC) com a biocarburant per autoconsum agrícola presenten alguns avantatges respecte al sistema tradicional de conreu de la ...

    Viabilitat tècnica i ambiental de biocombustibles: oli de colza i estella forestal 

    Esteban Dalmau, Bernat (Data de defensa: 2011-07-06)

    La dependència actual dels combustibles fòssils en la majoria de sectors industrials i domèstics no és sostenible ni a curt ni a llarg termini. Això està obligant a plantejar alternatives a la majoria de sectors industrials ...
