  1. 1. Experimental validation of PLAC8 in small intestinal neuroendocrine tumors

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Martin Nilsson; [2023]
    Nyckelord :;

    Sammanfattning : Small intestinal neuroendocrine tumors (SI-NETs) are the most common malignant tumor in the small bowel. It is a small-growing cancer with good overall survival 5 years after diagnosis, but no full cure is available when in the metastatic stage. LÄS MER

  3. 2. Mitigating SSCI in a hybrid wind and PV farm utilizing PV-STATCOM : A Swedish case study

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Isabelle Löfgren; [2022]
    Nyckelord :impedance analysis; PV-STATCOM; SSCI; SSO; SSR; sub-synchronous control interaction;

    Sammanfattning : The share of electricity generation in the power system being based on power electronics is increasing, which will impact the system in different ways, such as an increased risk for undesired interactions. An example is doubly fed induction generator (DFIG) based windfarms which have been shown to present negative resistance in (parts of) the sub-synchronous range (i. LÄS MER

  4. 3. Resonant overvoltages caused by transformer energization and saturation : Two EMT case studies conducted using models of the grid in Stockholm and an off-shore wind farm

    Master-uppsats, Uppsala universitet/Elektricitetslära

    Författare :Gustav Sundberg; [2021]
    Nyckelord :Resonant overvoltages; Resonance frequency; Parallel resonance; EMT studies; Transformer saturation; Off-shore wind power; Inrush current; Sympathetic Inrush; Resonanta överspänningar; Resonansfrekvens; Parallellresonans; EMT-studier; Magnetiseringsström; Havsbaserad vindkraft;

    Sammanfattning : This thesis investigates the impact of resonant overvoltages and their origin. Series and parallel resonances are present in any electrical grid. The frequency of which this resonance occurs is called resonance frequency. LÄS MER

  5. 4. Development of EMT components and reference grid in OpenModelica

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Alba Fernandez Horcajuelo; [2021]
    Nyckelord :Power system simulation; EMT simulation; Modelica; OpenModelica; Kraftsystemsimulering; EMT- simulering; Modelica; OpenModelica;

    Sammanfattning : Power systems simulation tools enable to study and evaluate the performance of electrical power systems in different scenarios. This allows the development and implementation of new solutions to the challenges electrical grids face nowadays. LÄS MER

  7. 5. Error Identification in Tourniquet Use : Error analysis of tourniquet use in trained and untrained populations

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Molly Lundberg; [2020]
    Nyckelord :tourniquet; bleeding control; error; task analysis; SHERPA;

    Sammanfattning : The number of prehospital deaths caused by large bleedings could be decreased if civilian people would act in time to help the injured patient. One way to help is to stop the bleeding with a tourniquet application. However, the tourniquet needs to be placed correctly in order to stop the bleeding. LÄS MER
