  1. 1. Modelling the global water cycle – the effect of Mg-sursassite on the amount of globally subducted water

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Nils Benjamin Gies; [2021-07-05]
    Keywords : ;

    Abstract : Subduction of hydrated lithospheric mantle is the most important process regarding the transfer of significant amounts of water to depths exceeding 350 km. Hence, the interplay of the thermal structure within the subducted slab together with the PT-stability fields of hydrous ultra-high pressure phases control the dehydration of the slab and the amount of water transported into the deeper mantle.

  3. 2. Performance of reinforced concrete bridges strengthened with Carbon Fiber Reinforced Polymers : Case study: Essinge Bridge over Pampaslänken

    University essay from KTH/Bro- och stålbyggnad; KTH/Jord- och bergmekanik

    Author : Zeinab Mirzahassanagha; Eva Malo; [2021]
    Keywords : CFRP; External Strengthening Method; RC Bridges; Curved Substrate; Finite Element Modelling; Kolfiberväv; Extern Förstärkningsmetod; Betongarmerade broar; Konkav yta; Finita Elementa Modellering;

    Abstract : This master thesis deals with the performance of existing reinforced concrete bridges strengthened with externally bonded carbon fibre reinforced polymers (CFRP). One of the main aims of this work is to understand the functionality of such an external strengthening method applied to a concave surface in a heavy concrete structure such as a bridge. READ MORE

  4. 3. Interpolation and visualization of sparse GPR data

    University essay from Umeå universitet/Institutionen för fysik

    Author : Rickard Sjödin; [2020]
    Keywords : GPR; Ground Penetrating Radar; Interpolation;

    Abstract : Ground Penetrating Radar is a tool for mapping the subsurface in a noninvasive way. The radar instrument transmits electromagnetic waves and records the resulting scattered field. Unfortunately, the data from a survey can be hard to interpret, and this holds extra true for non-experts in the field. The data are also usually in 2. READ MORE

  5. 4. Understanding Effects of Isothermal Heat Treatments on Microstructure of LMD-w Titanium Alloy (Ti-6242) : On solution heat treated microstructure

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Noomi Linder; [2020]
    Keywords : Heat Treatments Isothermal Titanium Alloy Ti-6242 Ti6242 Ti-6Al-2Sn-4Zr-2Mo GKN;

    Abstract : The use and knowledge of additive manufacturing technologies are rapidly growing. It is crucial to understand the processing-structure-property relationship, which is highly discussed when trying to understand the science of a material. One commonly used material in aerospace applications is titanium alloy, lately Ti-6Al-2Sn-4Zr-2Mo (Ti-6242). READ MORE

  6. 5. Assessment of static performance of LKAB´s welded mesh : Laboratory testing and analysis

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Fredrik Eriksson; [2020]
    Keywords : ;

    Abstract : Surface support is an areal support, which is installed on rock excavation surface to prevent bulking of rock mass and retain loose rock fragments. Welded wire mesh is one type of surface support. Literature study indicates that there is a wide range of testing methods on mesh. READ MORE
