    Abstract : Grid connection of wave energy is one of the crucial remaining areas of development towards the commercialization of this renewable energy technology. One of the major challenges with the grid connection of the wave energy technology is power variability. READ MORE

  4. 23. Changes in physical capacity and body composition from military basic training

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Hannes Fransson; [2020]
    Keywords : ;

    Abstract : Background: Military basic training is important to prepare the recruits for the physical demands that will be put on them during their service. Recruits need to be both strong and have a high aerobic capacity, which requires well-designed exercise plans. READ MORE

  5. 24. Simulating Low Frequency Reverberation in Rooms

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Mattias Svensson; [2020]
    Keywords : Low frequencies; Room acoustics; Finite Difference Time Domain method; FDTD.; Rumsakustik; låga frekvenser; Finite Difference Time Domain metoden; FDTD.;

    Abstract : The aim of this thesis was to make a practical tool for low frequency analysis in room acoustics.The need arises from Acad’s experience that their results from simulations using raytracing software deviate in the lower frequencies when compared to field measurements inrooms.

  6. 25. Identifying Power Quality Issues in LV Distribution Grid by Using Data from Smart Meters : Exploring possibilities of machine learning algorithms

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Samantha Chen; [2020]
    Keywords : ;

    Abstract : Since there is a significant potential to supervise the low voltage network with the assistance of the end-customer smart meters, Vattenfall Eldistribution AB wants to take advantage of such data. Therefore, this project’s overall goal is to investigate how some specific grid disturbances could be detected in certain meter data types. READ MORE
