  1. 1. The Paradigm Shift for Substations Technology within Wind Power Applications from Onshore to Floating

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

    Author : Ahmad Talaat Hifzy; [2023]
    Keywords : Floating; offshore; substation; transformer; GIS; equipment; high-voltage; fatigue; Flytande; havsbaserad; station; transformator; GIS; utrustning; högspänning; utmattning;

    Abstract : Floating wind turbines are attracting more attention as more than three-quarters of the total offshore technical potential is located in deep water, leading to a growing trend in floating wind farm projects. Consequently, it becomes necessary to develop Floating Offshore Substation (FOSS) to step up voltage and efficiently transmit power to the shore with minimal losses. READ MORE

  2. 2. Gravity water waves over constant vorticity flows: from laminar flows to touching waves

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Author : Francisco Gonçalves Jorge Dias de Carvalho; [2023]
    Keywords : Partial differential equations; Water waves; Euler equations; Free boundary problem; Bifurcation theory; Nonlinear functional analysis; Hilbert transform; Mathematics and Statistics;

    Abstract : In a recent paper, Hur and Wheeler proved the existence of periodic steady water waves over an infinitely deep, two-dimensional and constant vorticity flow and subject to gravity whose profile overhangs, among which, waves whose surface touches at a point, enclosing a bubble of air. We take this further, proving the existence of a continuous curve of water waves from a laminar flow up to a touching wave for fixed non-zero gravity. READ MORE

  3. 3. Neural Network-Based Residential Water End-Use Disaggregation

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

    Author : Cajsa Pierrou; [2023]
    Keywords : Residential water end-use; Flow disaggregation; Time series classification; Artificial neural network; Smart water meter; Slutanvändning av vatten i hushåll; Flödesdisaggregering; Tidsserieklassificering; Artificiella neurala nätverk; Smart vattenmätare;

    Abstract : Sustainable management of finite resources is vital for ensuring livable conditions for both current and future generations. Measuring the total water consumption of residential households at high temporal resolutions and automatically disaggregating the sole signal into classified end usages (e.g. READ MORE

  4. 4. Designing with water : exploring water as a design material for interactive experiences

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

    Author : Hallbjörg Embla Sigtryggsdóttir; [2023]
    Keywords : Water; Design toolkit; Interaction design; WaterHCI; Soma Design; Research Through Design; Vatten; Designverktygslåda; Interaktionsdesign; WaterHCI; Soma Design; Forskning via Design;

    Abstract : This project explores water as a design material for interactive experiences. The project follows a Research Through Design approach, incorporating methods from both material driven design and the soma design methodology. Over a period of two months, I engaged in first person explorations where I engaged deeply with the design material. READ MORE

  5. 5. Geochemical tracing of Arsenic sources in groundwater at the remediated Storliden mine, Skellefte district

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Matilda Edvardsson; [2021]
    Keywords : Arsenic; groundwater; Sulfide oxidation; Arsenopyrite; Storliden; remediation; Arsenik; grundvatten; sulfidoxidation; Arsenikkis; Storliden; efterbehandling;

    Abstract : The Swedish mining industry has changed from the historical situation with several smaller mines to the present situation with a few, bigger mines. This results in presence of abandoned mines around Sweden. Remediation of mines is regulated by legislation and the present demands are considerably higher than it was some decades ago. READ MORE
