    Sammanfattning : Cardiovascular diseases are a leading cause of death globally. Early diagnosis and treatment is of prime importance to prevent or mitigate health complications. Electrocardiogram (ECG) is a standard test modality used for early diagnosis of arrhythmias. The standard ECG uses 12 leads (i. LÄS MER

  3. 3. Inversa problem för resistornätverk

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Emma Mattsson; Felicia Eriksson; [2021]
    Nyckelord :;

    Sammanfattning : I alla elektriska apparater finns det elektriska kretsar som behövs för att kunna utnyttja strömmens energi, som i sin tur gör att apparaten kan fungera. Antag att den elektriska kretsen, enbart består av resistorer, har en känd struktur men att resistorernas resistanser är okänd. LÄS MER

  4. 4. Delivering sustainable energy transition : A techno-economic analysis on households, businesses and communities of the Keweenaw Peninsula

    Master-uppsats, KTH/Energiteknik

    Författare :Francesca Longobardi; Filippo Padovani; [2020]
    Nyckelord :;

    Sammanfattning : Energy security understood as the practice by which risks associated with interruptions to the energy supply are low, represents one of the main objectives of energy policies in many countries. In this context, Keweenaw County or Michigan's northernmost County is placed as locked in an unreliable, unsustainable and particularly wasteful energy system. LÄS MER

  5. 5. Performance evaluation and development of contact solutions for flexible organic solar cells

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik
