  1. 1. High levels of nickel from sulphide soil in Umeå's raw water : Modeling of groundwater flow and mass transport in Forslunda aquifer

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

    Författare :Merhawi Belai; [2024]
    Nyckelord :nickel; sulfide; sulphide; groundwater; modeling; mass transport; Feflow; Umeå; nickel; sulfid; monosulfid; grundvatten; modellering; masstransport; Feflow; Umeå;

    Sammanfattning : The raw water in some of Umeå's abstraction wells has shown high nickel levels for more than a decade. The cause has not been determined but there is an investigation from 2010 where the results indicate sulphide clay found adjacent to two basins used for artificial infiltration. LÄS MER

    Sammanfattning : I dagens affärsmiljö strävar många organisationer efter att automatisera processen för att hämta information från fakturor. Målet är att göra hanteringen av stora mängder fakturor mer effektiv. Trots detta möter man utmaningar på grund av den varierande strukturen hos fakturor. LÄS MER

  4. 3. Detecting Lithium Brine in Afghanistan Using Spaceborne Hyperspectral Data

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Torpikay Azizi; [2023-08-18]
    Nyckelord :PRISMA Hyperspectral data; lithium mineral deposits; lithium brine-rich deposits; Dashti-e- Nawar; boron deposits; Principal Component Analysis PCA ; supervised and unsupervised classification; spectral matching; spectral profile analysis; visible-near-infrared VNIR ; short-wave infrared SWIR Gypsum; Hectorite; Kaolinite; Lepidolite; lithium carbonate; lithium chloride;

    Sammanfattning : The purpose of this thesis is to utilize hyperspectral remote sensing technology for the identification and evaluation of lithium mineral deposits in Afghanistan. Afghanistan boasts unique geological formations with substantial potential for lithium resources beneath its land crust. LÄS MER

  5. 4. TRANSPARENCY AND THE RESOURCE CURSE IN GHANA: A CASE STUDY Changes since oil discovery

    Kandidat-uppsats, Göteborgs universitet/Statsvetenskapliga institutionen

    Författare :Amanda Alagic; [2023-06-29]
    Nyckelord :Resources curse; Ghana; Transparency; Oil; Corruption;

    Sammanfattning : When a country has high levels of natural resources, they risk falling prey to the resource curse. Studies show a correlation between high levels of natural resources and corruption as well as lower quality institutions and less democracy. Transparency is a key precondition for accountability and mitigating corruption. LÄS MER

  7. 5. Syntax-based Concept Alignment for Machine Translation

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Arianna Masciolini; [2023-03-30]
    Nyckelord :computational linguistic; machine translation; concept alignment; syntax; dependency parsing; Universal Dependencies; Grammatical Framework;

    Sammanfattning : This thesis presents a syntax-based approach to Concept Alignment (CA), the task of finding semantical correspondences between parts of multilingual parallel texts, with a focus on Machine Translation (MT). Two variants of CA are taken into account: Concept Extraction (CE), whose aim is to identify new concepts by means of mere linguistic comparison, and Concept Propagation (CP), which consists in looking for the translation equivalents of a set of known concepts in a new language.
