  1. 1. Comparison of Magnetic-Susceptibility Models From UAV-borne and Ground Measurements in Enåsen Area, Sweden

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Clara Sjödin; [2022]
    Nyckelord :magnetic susceptibility; Enåsen area; UAV survey; magnetic anomalies; Potent; magnetisk susceptibilitet; Enåsen; drönare; magnetiska anomalier; Potent;

    Sammanfattning : Mapping anomalies in the Earth’s magnetic field is one method used in applied geophysics, for exploring buried structures and objects. Magnetic surveys can be ground-based or made airborne, onboard airplanes, helicopters, or unmanned aerial vehicles (UAV), also known as drones. LÄS MER

  3. 2. Integration of geology with geophysics : Case studies from Svalbard

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Sofia Rylander; Anna Sterley; [2022]
    Nyckelord :Gravity Measurements; Magnetic Measurements; Anomalies; Seismic; Fault Zones; Svalbard;

    Sammanfattning : This is a study where new and old geophysical data together with information found in literature has been integrated to get a better understanding of the geological evolution of Svalbard. The purpose of the study is to acquire and integrate different geophysical data over the Central Spitsbergen Basin (CSB) and across the Billefjorden Fault Zone (BFZ). LÄS MER

    Sammanfattning : Synchrotron and Free Electron Laser (FEL) light is becoming an increasingly sought after tool for almost all scientific research aspects. MAX IV Laboratory introduced the first 4th generation light source that provides the brightest synchrotron light in the world. LÄS MER

  5. 4. Automation Pipelines for Efficient and Robust Experimental Research Within Cognitive Neuroscience

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktion

    Författare :Patrik Björklund; Anna Rydin; [2020]
    Nyckelord :Computer Vision; Visual Analog Scale; VAS; Questionnaires; Research Pipeline; Automation; Anomaly Detection;

    Sammanfattning : The current trend towards large-scale research projects with big quantities of data from multiple sources require robust and efficient data handling. This thesis explores techniques for automatizing research data pipelines. Specifically, two tasks related to automation within a long-term research project in cognitive neuroscience are addressed.

  7. 5. Geophysical investigation of the Arvidsjaur volcanics and the Archean-Proterozoic boundary

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

    Författare :Erik Bjänndal; [2019]
    Nyckelord :Laver SimPEG MT Magnetotelluric Magnetic Inversion;

    Sammanfattning : In this work the magnetic and magnetotelluric (MT) geophysical methods have been used to produce two 3D models for the Laver area in southern Norrbotten. A new discovery of a porphyry copper deposit located at the Lill-Laverberget was reported by Boliden in 2012. LÄS MER
