  1. 1. Process parameter optimisation for Waspaloy using Laser-Directed Energy Deposition with Powder

    Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Johannes Lövhall; [2024]
    Nyckelord :Process parameter optimisation; Waspaloy; Laser-Directed Energy Deposition with Powder;

    Sammanfattning : Material utilisation is of importance in the manufacturing industry formaking the most of each material, minimising waste and increasing cost-effectiveness. In this thesis, samples of Waspaloy built with the method of L-DED-P has been analysed in order to investigate how process pa-rameters influence the build quality and geometrical accuracy in as-builtobjects.

  3. 2. Data-driven Discovery of Real-time Road Compaction Parameters

    Master-uppsats, KTH/Matematisk statistik

    Författare :Yuqi Shao; [2022]
    Nyckelord :statistics; machine learning; road compaction; statistik; maskininlärning; vägpackning;

    Sammanfattning : Road compaction is the last and important stage in road construction. Both under-compaction and over-compaction are inappropriate and may lead to road failures. Intelligent compactors has enabled data gathering and edge computing functionalities, which introduces possibilities in data-driven compaction control. LÄS MER

  4. 3. Study of the Resistive Switching Mechanism in Novel Ultra-thin Organic-inorganic Dielectric-based RRAM through Electrical Observations

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Alba Maria Martinez Garcia; [2021]
    Nyckelord :Resistive random-access memory RRAM ; flexible electronics; organic-inorganic hybrid dielectric; dual-mode conducting filament; electrical programming; Resistivt slumpmässigt åtkomstminne RRAM ; flexibel elektronik; organisk-oorganisk hybrid dielektrikum; dubbelt läge ledande glödtråd; elektrisk programmering;

    Sammanfattning : The promising role resistive random-access memory (RRAM) plays in the imminent reality of wearable electronics calls for a new, updated physical model of their operating mechanism. Their high applicability as the next-generation flexible non-volatile memory (NVM) devices has promoted the recent emergence of a novel ultra-thin (< 5nm) organic/inorganic hybrid dielectric RRAM.

  5. 4. Material parameter identification of a thermoplastic using full-field calibration

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Nikhil Prabhu; [2020]
    Nyckelord :DIC; FFC; Thermoplastics; Material parameter identification; multi-point history; Polyamide 6; GISSMO; Response Surface Methodology;

    Sammanfattning : Finite element simulation of thermoplastic components is gaining importance as the companies aim to avoid overdesign of the components. Cost of the component can be minimized by using an adequate amount of material for its application. LÄS MER

  7. 5. Design Parameter Identification and Verification for Thermoplastic Inserts

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Malhar Ozarkar; [2020]
    Nyckelord :Contact modelling; experimental validation; thermoplastic material; metamodel based design optimization.;

    Sammanfattning : Inserts are a crucial part of household and industrial furniture. These small plastic parts which often go unnoticed to the naked eye perform crucial functions like providing a base for the furniture, leveling the furniture, safeguarding the user from edges of the tubes used and providing an aesthetic finish.
