  1. 1. Buildings in the Digital Era : An Explorative Study of Digital Twins in the Built Environment

    Master-uppsats, KTH/Industriell ekonomi och organisation (Inst.)

    Författare :Siw Kristine Kästel; Joanna Wallén; [2024]
    Nyckelord :Digital Twin DT ; Arcitecture; Engineering and Construction AEC industry; Digitization; Building Information Modeling BIM ; Facility Management FM ; Operation Management O M ; Digital Tvilling; Fastighetsbranschen; Fastighetsförvaltning; Byggnadsinformationsmodeller BIM ;

    Sammanfattning : In recent years, digital twins (DT) have gained traction in enhancing operation and maintenance procedures across various industrial sectors, such as manufacturing, energy, and aerospace. Yet their utilization remains more limited in the built environment. LÄS MER

  3. 2. En modern porträttering av en levande myt : En tematisk analys av The New York Times från 2017 till 2023 kring UFO-fenomenet

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för medier och journalistik (MJ)

    Författare :Anton Aldén; Magnus Bruhn; [2024]
    Nyckelord :UFO; UAP; Flying Saucers; Myth; Journalism;

    Sammanfattning : Over the last years the UFO-phenomenon has created considerable attraction in US-media. The reasons are twofold: 1) Since the fall of 2017 there has been an increased official acknowledgement of the phenomena 2) Several spectacular revelations have been publicized, both triggering a lager media coverage.

  4. 3. Increasing the diodicity of ceramic Tesla valves by exploiting the design freedom of additive manufacturing : A study in design optimizations of Tesla valves for ceramic 3D printing

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Udit Sharma; [2024]
    Nyckelord :additive; manufacturing; Tesla; valve; ceramic; 3D; printing;

    Sammanfattning : The work presented in this thesis was conducted at Uppsala University and at Fraunhofer IKTS, Dresden. The thesis aims to study design optimizations for increasing the diodicity and thereby performance of a Tesla valve, a type of “no moving parts” (NMP) valve, through design freedoms offered by ceramic additive manufacturing.

  5. 4. Conjugate Heat Transfer Analysis of HPGP Thruster

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Lisa Svensson; [2024]
    Nyckelord :aerospace; HPGP; ECAPS; ANSYS; conjugate heat transfer; thruster; space;

    Sammanfattning : This master's thesis was conducted in collaboration with ECAPS, where a conjugate heat transfer analysis on their High Performance Green Propulsion (HPGP) 22N thruster was done. ECAPS is a Swedish propulsion company specializing in green propulsion. They develop thrusters for spacecraft orbit and attitude control, utilizing the propellant LMP-103S. LÄS MER

  7. 5. Real-Time Navigation for Swarms of Synthetic Aperture Radar (SAR) Satellites

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Antoni Eritja Olivella; [2024]
    Nyckelord :SAR; Real-time orbit determination; Real-time baseline determination; swarms; satellite; formation flying;

    Sammanfattning : The pursuit of precision and flexibility in satellite missions has led to an increased number of formation flying missions being developed. These systems consist of multiple satellites flying at close distances (from a few kilometres to a few meters) to achieve common objectives. LÄS MER
