  1. 1. Mapping of Dependent Structural Responses on a Prestressed Concrete Bridge using Machine Learning Regression Analysis and Historical Data : A Comparison of Different Non-linear Regression Approaches

    L1-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Vedad Coric; [2023]
    Nyckelord :Prestressed Concrete Bridges; Structural health Monitoring; Machine Learning; Regression analysis; Infrastructure management;

    Sammanfattning : Prestressed concrete bridges are susceptible to deterioration over time which might significantly affect their capacity and overall performance. In previous decades, infrastructure owners have found that continuous monitoring of these assets is a valuable tool for their management as it facilitates the decision-making process regarding the intervention strategies required.

  2. 2. Uppvärmning av växthus med låga vattentemperaturer : Prov med värmevatten mellan två plastfilmer

    Kandidat-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Magnus Ros; Mattias Vik; [2021]
    Nyckelord :Greenhouse; energy efficiency; heating system; waste heat; district heating; growing.; Växthus; energieffektivisering; uppvärmningssystem; spillvärme; fjärrvärme; odling;

    Sammanfattning : Idag produceras en stor del av grönsakerna som konsumeras i Sverige utomlands och transporteras till butiker och konsumenter i Sverige. Anledningen att Sverige idag inte producerar tomater, grönsaker och sallad med mera året runt är för att energianvändningen till att hålla växthusen varma under vinterhalvåret är stor och medför stora kostnader.

  3. 3. A Relation Between Anderson Acceleration and GMRES

    Kandidat-uppsats, Lunds universitet/Matematikcentrum

    Författare :Gustaf Lorentzon; [2020]
    Nyckelord :Numerical analysis; acceleration methods; fixed-point iteration; generalized minimal residual method; GMRES; iterative methods; numerical linear algebra; finite difference method; Mathematics and Statistics;

    Sammanfattning : A very common type of problem within mathematics and numerical analysis are fixed-point problems, which can arise as sub-problems of optimization methods, differential equations solvers and much more. The most basic iterative approach for fixed-point problems is fixed-point iteration, special cases of which actually date back as far as the Babylonians, where it was used to to find the square roots of positive numbers.

  4. 4. Effects of biochar on the water-holding capacity of soils : field experiments in asparagus cultivation capacity of soils on Gotland

    Kandidat-uppsats, SLU/Dept. of Soil and Environment

    Författare :Malin Pettersson Silvén; [2020]
    Nyckelord :Waila AB; water-holding capacity;

    Sammanfattning : Biochar is a residual product that is produced by combustion of organic material at a restricted amount of oxygen, so called pyrolysis. It has been seen that biochar could have positive effects when incorporated in soils, such as increasing the water-holding capacity and decreasing the dry bulk density. LÄS MER

  5. 5. Proximate Determinants of Sustainable Economic Growth in Rwanda : -An empirical investigation

    Magister-uppsats, Umeå universitet/Nationalekonomi

    Författare :Pascal Kamana; [2020]
    Nyckelord :;

    Sammanfattning : This study analyses proximate determinants of sustainable economic growth in Rwanda. The study asks whether growth of agriculture, foreign aid and change in climate conditions are drivers of a sustainable economic growth experience in Rwanda. The Solow growth model is used as theoretical framework and TFPG is derived as the Solow residual. LÄS MER
