  1. 1. Heterogeneous catalytic reactions studied with transient gas supply and event-averaged ambient pressure x-ray photoelectron spectroscopy

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for Nanoscience

    Författare :Qianhui Liu; [2022]
    Nyckelord :Ambient pressure x-ray photoelectron spectroscopy; Event-averaging; Pd 100 surface structure oscillation; Physics and Astronomy;

    Sammanfattning : CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially.

  3. 2. Predicting PV self-consumption in villas with machine learning

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :FABIAN GALLI; [2021]
    Nyckelord :Self-Consumption; photovoltaics; machine learning; solar energy; Random Forest; K-nearest neighbor; multi-layer perceptron; lasso regression; ridge regression; linear regression; prediction; Egenanvändning; photovoltaics; maskininlärning; solenergi; Random Forest; K-nearest neighbors; multi-layer perceptron; lasso regression; ridge regression; linjär regression; data-förutsägelse;

    Sammanfattning : In Sweden, there is a strong and growing interest in solar power. In recent years, photovoltaic (PV) system installations have increased dramatically and a large part are distributed grid connected PV systems i.e. rooftop installations. LÄS MER

  4. 3. Assessing the Potential of Hydroponic Farming to Reduce Food Imports: The Case of Lettuce Production in Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Rouzbeh Taghizadeh; [2021]
    Nyckelord :Sustainable Development; Urban Agriculture; Hydroponics; Food Import; Lettuce Production;

    Sammanfattning : Many studies have investigated the issue of feeding the world’s growing population from different perspectives. Conventional agricultural methods usually have small production yields while requiring large amounts of scarce and unevenly distributed resources such as farmland and water. LÄS MER

  5. 4. Food Security in Swedish Crisis and Contingency Policy : What's the problem represented to be?

    Master-uppsats, Försvarshögskolan

    Författare :Hannah Stewart; [2021]
    Nyckelord :Food Security; crisis and contingency policy; civil preparedness;

    Sammanfattning : Most countries in the Global North have enjoyed relative food security over the past decades, but recent events such as the Covid-19 pandemic have highlighted how global food supply chains are fragile and susceptible to be affected by a range of disturbances. In Sweden, a revived interest for civil defense planning has led to a policy shift with new government instructions to plan for food security in the event of a crisis or war. LÄS MER

  7. 5. China-Africa Relations and Imperialism: Towards an End of the Debate : Testing Imperialism Theory on The Case Of China And Angola

    Kandidat-uppsats, Stockholms universitet/Institutionen för ekonomisk historia och internationella relationer

    Författare :Benjamin Gustavsson; [2021]
    Nyckelord :China-Africa Relations; Imperialism; Colonialism; China; Angola; Africa; Development; Underdevelopment; Capitalism; Kina-Afrika-relationer; Imperialism; Kolonialism; Kina; Angola; Afrika; Utveckling; Underutveckling; Kapitalism;

    Sammanfattning : This study assesses the popular claim that Chinese engagement in Africa is imperialism through a case study of relations between China and Angola. Using Marxist imperialism theory as point of departure, it develops a comprehensive theoretical framework for testing the hypothesis that China is imperialist in its relations with Angola. LÄS MER
