    Sammanfattning : So-called ancillary services (AS) have always been critically important for the functioning of an electrical grid, and are becoming even more so with the advent of renewable energy sources. Ancillary services are traded on open markets, and trading on these markets is arguably even more difficult to model than on traditional markets. LÄS MER

  3. 2. Trigonometric series with monotone coefficients

    Kandidat-uppsats, Institutionen för ingenjörsvetenskap, fysik och matematik

    Författare :Jona Ekström; [2007]
    Nyckelord :Trigonometric series; Fourier series;

    Sammanfattning : This work is devoted to trigonometric series with monotone coefficients. The main problem is to study conditions under which a given series is the Fourier series of an integrable (or continuous) function. .. LÄS MER
