    • Wireless Charging for Small Electric Vessels 

      Omosanya, Hafeez Abolade (Master thesis; Mastergradsoppgave, 2019-06-28)
      With the presence of traditional thick and heavy cables for charging, the risk of humans exposed to high-voltage, and due to mechanical wear and tear in conductive materials, inductive wireless charging was introduced which is the future of charging technology. This project has focused on magnetic-coupled wireless transfer with some key components involved such as a DC voltage source, a full-bridge ...

    • Wireless charging of offshore wind service vessels 

      Nilsen, Henrik Fjeld (Master thesis; Mastergradsoppgave, 2021-05-18)
      This report discusses the possibility for wireless charging solutions for electric vessels, with a focus on offshore wind turbine service. Where the charging time is minimal and safety for crew is important. Different types of wireless technologies have been studied, where the Inductive power transfer (IPT) is shown to be the preferred technology. Inductive power transfer (IPT) grants a safe ...

    • Wireless industrial indoor localization and its application 

      Hu, Junsheng (Master thesis; Mastergradsoppgave, 2017-06-14)
      A complete, structural and comprehensive description of indoor localization technology is pre-sented in this paper. It concluded the basic techniques for distance measurement in indoor locali-zation, the basic localize principles, the topologies and algorithms which are often used in indoor localization area. Then how to perform indoor localization with sensors which are available in modern smartphones ...

    • Working Chair for Physically Disabled Children 

      Larsson, Ludvig (Master thesis; Mastergradsoppgave, 2019-06-28)
      A product development process was initiated with the purpose of designing a saddle seat working chair for physically disabled children on behalf of Fysionord AB. An objectives tree diagram was made using Mindomo.com. Sub-functions in existing solutions were listed, leading to the discovery of four modules, constituting the working chair: footrest, seat, backrest and undercarriage with wheels. The ...

    • Zonal Day-Ahead Energy Market: A Modified Version of the IEEE 39-bus Test System 

      Tricarico, Gioacchino; Wagle, Raju; Dicorato, Maria; Forte, Giuseppe; Gonzalez-Longatt, Francisco; Torres, José Luis Rueda (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-11)
      The increasing penetration of renewable energy resources (RES) in transmission system operating conditions require a suitable test system and a dataset to cope with current issues. RES penetration remarkably affects day-ahead market outcomes regarding zonal prices and dispatched generation levels. For this purpose, zonal day-ahead energy market models in the presence of RES in the generation mix ...

    • Zonal modeling of air distribution impact on the long-range airborne transmission risk of SARS-CoV-2 

      Aganovic, Amar; Cao, Guangyu; Kurnitski, Jarek; Melikov, Arsen; Wargocki, Pawel (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-28)
      A widely used analytical model to quantitatively assess airborne infection risk is the Wells-Riley model which is limited to complete air mixing in a single zone. However, this assumption tends not to be feasible (or reality) for many situations. This study aimed to extend the Wells-Riley model so that the infection risk can be calculated in spaces where complete mixing is not present. Some more ...
