  1. 1. Gate driver solutions for high power density SMPS using Silicon Carbide MOSFETs

    Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Farhan Akram; [2021]
    Nyckelord :SiC MOSFETs; Gate drivers; DC-DC converter; High power and efficiency power supplies;

    Sammanfattning : Discrete silicon carbide (SiC) power devices have unique characteristics that outpace those of silicon (Si) counterparts. The improved physical features have provided better faster switching, greater current densities, lower on-resistance, and temperature performances. LÄS MER

  3. 2. A Freundlich-based model for prediction of pH-dependent sulfate adsorption in forest soil.

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Muhammad Akram; [2015]
    Nyckelord :Sulfate; Spodosols; pH Dependent Sulfate Adsorption; Extended Freundlich Model;

    Sammanfattning : The period of industrialization after the second World War in Europe released SO2 and NOx by combustion of fossil fuels and contributed the formation of S and N compounds in the forest ecosystem. The Swedish forest soil systems were influenced by emissions of SO2 followed by H2SO4 deposition, consequently the pool of SO42- had increased in the forest ecosystem. LÄS MER

  4. 3. Inverkan av takabsorbenter och ljudisolering på talavskildheten mellan rum

    Kandidat-uppsats, Lunds universitet/Utbildningar i Helsingborg

    Författare :Akram Abdul Hamid; Irfan Ibrahimovic; [2011]
    Nyckelord :ljud; isolering; absorbenter; undertak; akustik; tal; avskildhet; Technology and Engineering;

    Sammanfattning : We have examined and analyzed the impact of ceiling sound absorbers and sound insulation in a false ceiling, on the speech privacy between two adjacent rooms. We concluded that they had a significant impact on the speech privacy and that the combination of ceiling sound absorbers with sound insulation in the false ceiling was the best option from an acoustic point of view.

  5. 4. Functional Approach towards Approximation Problem

    Master-uppsats, Blekinge Tekniska Högskola/Avdelningen för för interaktion och systemdesign

    Författare :Muhammmad Imran Shafi; Muhammad Akram; [2008]
    Nyckelord :Approximation algorithms; functional languages; imperative languages; bipartite graph; Haskell;

    Sammanfattning : Approximation algorithms are widely used for problems related to computational geometry, complex optimization problems, discrete min-max problems and NP-hard and space hard problems. Due to the complex nature of such problems, imperative languages are perhaps not the best-suited solution when it comes to their actual implementation. LÄS MER
