  1. 1. A Solidarity Model of Foreign Aid? : A case study of the Olof Palme International Center’s projects in South Africa

    Kandidat-uppsats, Högskolan Väst/Institutionen för ekonomi och it

    Författare :Malin Stål; [2023]
    Nyckelord :Foreign aid; international solidarity; charity; non-governmental organisation; development aid; South Africa; Sweden; Olof Palme International Center; Utländskt bistånd; internationell solidaritet; välgörenhet; icke-statliga organisationer; bistånd; Sydafrika; Sverige; Olof Palmes internationella center;

    Sammanfattning : This bachelor thesis is a qualitative case study of whether the Olof Palme International Center’s (OPC) model of foreign aid, as a Swedish non-governmental organisation (NGO), is understood by leading figures of the three types of participants involved in the model; the OPC, Swedish member organisations, and, in this case, South African partner organisations, as taking either a solidarity- or charity-approach to foreign aid, in both theory and practise. The theories of Mutual Aid and International Solidarity are used to construct two opposing “solidarity” and “charity” models of foreign aid, against which the OPC model is compared. LÄS MER

  3. 2. Recovery of Dialcohol Cellulose using Micro- and Ultrafiltration Processes

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Lina Näslund; Gabriella Petersson; [2023]
    Nyckelord :Membrane filtration; Ultrafiltration; Microfiltration; Dialcohol cellulose; DAC; Bioplastics; Chemical engineering; Process design; Technology and Engineering;

    Sammanfattning : The waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. LÄS MER

  4. 3. Embedded digital filter design and implementation

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Xiao Su; [2023]
    Nyckelord :;

    Sammanfattning : Digital filters have been widely used in signal processing, to reduce or remove unwanted signals of different types, such as noise, and interference, and to enhance or keep desired signals. They are implemented as algorithms on an embedded system (a microcontroller) or a computer.

  5. 4. Leveraging green hydrogen to decarbonise the aviation industry : A case study on electrofuels in Sweden

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

    Författare :Jakob Bergene; Jonathan Bruchhausen; [2023]
    Nyckelord :Electrofuel; e-fuel; electrokerosene; e-kerosene; SAF; sustainable aviation fuel; sustainable aviation; complementarity formation mechanisms; technology value chains; TVC; Techno-economic analysis; TEA; Elektrobränsle; e-bränsle; elektrofotogen; e-fotogen; SAF; sustainable aviation fuel; sustainable aviation; komplementära formationsmekanismer; technology value chains; TVC; Techno-economic analysis; TEA;

    Sammanfattning : For the EU to reach its 2050 climate targets the aviation industry that is highly dependent on fossil fuels needs to drastically reduce its emissions. In the decarbonisation of the aviation industry drop-in sustainable aviation fuels (SAFs) have been identified as a promising solution to abate the industry’s emissions. LÄS MER

  7. 5. Development of an embedded system platform for signal analysis and processing

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Philip Lind; [2023]
    Nyckelord :Digital signal processing; DSP; digital filter; FIR; IIR; Butterworth; Chebychev; windowed sinc; Digital signalbehandling; DSP; digitalt filter; FIR; IIR; Butterworth; Chebychev; sinc; fönstermetoder;

    Sammanfattning : Information is often stored and transmitted through electrical signals. This information may need refinement, which may be done by processing and altering the electrical signals, in which it is transmitted. When refining a signal, a frequency selective filter is often used. It can be implemented through digital signal processing (DSP). LÄS MER
