  1. 1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Grigore-Leon Ratiu; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. LÄS MER

  3. 2. Predicting inflow and infiltration to wastewater networks based on temperature measurements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Martin Åsell; [2024]
    Nyckelord :Inflow and Infiltration; I I; CNN; Linear regression;

    Sammanfattning : Sewer pipelines are deteriorating due to aging and sub optimal material selections, leading to the infiltration of clean ground and rainfall water into the pipes. It is estimated that a significant portion (up to 40-50%) of the water entering wastewater treatment plants is actually clean infiltrated water. LÄS MER

  4. 3. Techno-economic analysis and simulation of low temperature district heating networks

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Ilia Iarkov; [2023]
    Nyckelord :Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

    Sammanfattning : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. LÄS MER

  5. 4. Effects of Energy Performance Improving Measures on a 1990's Brick House in Southern Czech Republic : Computer Simulations using IDA-ICE

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Vaclav Panek; [2023]
    Nyckelord :Final energy demand; Primary energy demand; Energy performance; Refurbishment; Single-family house; Space heating;

    Sammanfattning : The residential sector was responsible for 25% of the Final Energy Demand (FED) in the European Union in 2015. Countries in Central and Eastern Europe such as the Czech Republic are particularly concerned with ensuring security of supply at the lowest possible cost in recent years. LÄS MER

  7. 5. Modelling the Water Table in a Bog

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Tobias Bowley; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Over the past five years, an ongoing study at INES, Lund University, have examined the encroachment of trees and vegetation into a bog ecosystem in northern Scania, Sweden. While several factors have been identified as contributing to this ecological transformation, including, nutrient availability, and climate, the hydrological aspect remains a key area of investigation.
