  1. 1. Rock Wedge Stability Assessment : A Comparative Analysis of Limit Equilibrium and Discrete Element Methods

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Vilma Nordh; [2024]
    Nyckelord :Numerical modelling; wedge stability; 3DEC; UnWedge;

    Sammanfattning : Rock wedge stability is a common concern in underground excavations. Since the wedge stability influences the support design, it is important to use a wedge stability analysis method that can capture factors like excavation geometry, joint parameters and properties, rock mass properties, rock cover, and stress field as accurately as possible.

  3. 2. Vehicle dynamics modelling of electromagnetic suspensions for MAGLEV applications

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Léa Chatelais; [2024]
    Nyckelord :MAGLEV; Dynamics; Requirements; Suspension; Vehicle modeling; MATLAB; MAGLEV; Dynamisk; Fordran; Upphängning; Fordon modell; MATLAB;

    Sammanfattning : MAGnetic LEVitation Guidance System (MAGLEV) technology was commercially introduced relatively recently in the guided transport field. It is based on removing the wheels and rails of classic railway systems and supporting and guiding the train with magnets and magnetic forces instead. LÄS MER

  4. 3. Att ha ett jobb som alla andra. Möjligheter och utmaningar i övergången från gymnasiesärskolan till arbete: en kritisk forskningsöversikt

    Magister-uppsats, Göteborgs universitet/Institutionen för pedagogik och specialpedagogik

    Författare :Jacob Takeuchi; [2023-09-05]

  5. 4. In Pursuit of Legitimacy: A Decade of Non-Financial Reporting in the European Automotive Industry

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Lukas Lidvall; Viktor Rafstedt; [2023-07-04]
    Nyckelord :;

    Sammanfattning : Non-Financial Reporting (NFR) has grown significantly in importance within corporate reporting, particularly in the automotive industry, which is struggling with substantial inherent environmental challenges. However, at the same time, many argue that the NFR in the automotive industry is lackluster and riddled with inconsistencies and information overload. LÄS MER

  7. 5. Method to statistically secure field test results for rock drilling tools

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Frida Olander; [2023]
    Nyckelord :Statistics; Probability; Hypothesis test; Linear regression;

    Sammanfattning : The aim of this project is to find a statistical method that describes survival and outcome of a prototype drilling tool from several references and determine how many references are needed for a statistically secure result. The project also answers which variables that affects the outcome. LÄS MER
