  1. 1. Multiscale Analysis of Multifunctional Composites

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Ammara Dil; [2019]
    Nyckelord :;

    Sammanfattning : Conventional polymer composites are highly demanding due to their high strength and stiffness, low weight, easy processing and corrosion resistance. However, their weak out of plane properties restricts their use in high performance applications, such as aerospace, military and automotive components. LÄS MER

  2. 2. Multifunctional Wood Polymer Composites Reinforced with Graphene Nanoplatelets : Investigating if multifunctionality can be achieved in wood polymer composites through the addition of graphene nanoplatelets

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Vanessa Meulenberg; [2019]
    Nyckelord :Wood polymer composites; graphene; multifunctional; wood flour;

    Sammanfattning : Graphene nanoplatelets (GNPs) were used to reinforce wood polymer composites (WPCs) in order to achieve multifunctionality. Multifunctionality could be achieved through the GNPs because of their excellent mechanical and electrical properties. The research consists of two parts: HDPE/GNP/WF composites and LLDPE/GNP composites. LÄS MER

  3. 3. Energilager i Luleå Energis elnät

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Johanna Helmvall; [2019]
    Nyckelord :Energilager; batterilager; solceller; förnybar energi; effektbrist;

    Sammanfattning : This thesis will investigate possible energy storages in Luleå Energi’s power grid within a five-year period. The transition to a more sustainable and efficient energy system, in response to climate change, creates new challenges for the power grid. LÄS MER

  4. 4. Diffuse correlation spectroscopy for estimation of coagulation thickness : a phantom study

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Zeyneb Alsadi; [2019]
    Nyckelord :DCS; Diffuse correlation spectroscopy; Biomedical optics; coagulation; phantom study; coagulation depth; coagulation thickness; diffusion; model; two layer model;

    Sammanfattning : The objective of this preliminary study was to determine the potential of diffuse correlation spectroscopy (DCS) for assessment of coagulation depth. Coagulation of tissue can occur due to a number of different reasons such as thermal or electrical burns or radiofrequency ablation. LÄS MER

  5. 5. Applied State of Health Estimation Methods for Lithium-ion Batteries

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Simon Malmberg; [2019]
    Nyckelord :Litium-ion State of health battery batteries Estimation method Alelion;

    Sammanfattning : The ongoing shift towards a sustainable transportation sector is a hot topic. Lithiumion battery technology has become a key element in electrification due to its highenergy density and favourable electrical properties. The non-measurable chargeandhealth states of a battery are desirable to estimate for safety, performanceand economic reasons. LÄS MER
