  1. 21. 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

  3. 22. Acute response in body composition to fed versus fasted high intensity training in young healthy men

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Durim Skenderi; [2020]
    Keywords : ;

    Abstract : Background: High bodyfat is linked to a greater risk of chronic diseases for example diabetestype 2 and cardiovascular diseases. This has led to body composition analysis being a way ofmeasuring overall health. There are different ways to perform the body composition analysis. READ MORE

  4. 23. Automated visual evaluation of an electrode with neural networks

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

    Author : Lovisa Colérus; [2019]
    Keywords : ;

    Abstract : This project was done in cooperation with the company Scibase. Scibase producesa product called Nevisense, which is used to detect skin cancer in a noninvasiveway. The measurements are made with electrical impulses and the electrodethat is in contact with the patients’ skin is only used once. READ MORE

  5. 24. Non-invasive ultrasound measurements of vascular impedance

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Roger Larsson; [2018]
    Keywords : Ultrasound; ultrafast ultrasound imaging; vascular impedance; pulse wave velocity; motion tracking; Technology and Engineering;

    Abstract : Despite its introduction in the early 1950´s, vascular impedance has yet to be applied in clinical use to predict early stages of cardiovascular disease (CVD). It is defined as the ratio between blood pressure and flow and describes the opposition to blood flow within the cardiovascular system. READ MORE

  6. 25. Design of Resonant Filters for AC Current Magnification : Heating of Li-ion Batteries by Using AC Currents

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

    Author : Nikolina Djekanovic; [2018]
    Keywords : Current control; injection of alternating current; internal heat dissipation; LCL filter; Lithium-ion batteries; power efficiency; resonance phenomenon;

    Abstract : Using alternating current in order to heat batteries at sub-zero temperatures is a method,which is investigated in-depth by an increasing number of study groups. The thesis considersthe resonance phenomenon with the intention to use alternating current amplificationand battery’s impedance in order to induce power dissipation inside the battery, and in thisway increase its temperature.
