  1. 1. The effect of cross-border mergers & acquisitions as a driver of better corporate sustainability practices - A study on the post-acquisition context of selected target firms from Sri Lanka and Sweden

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Buddhini Erosha Jayasinghe; Farjana Rifat; [2023-07-19]
    Nyckelord :Mergers and acquisitions M A ; cross-border; sustainability; corporate sustainability practices; Corporate Social Responsibility CSR ; Environmental-Social-Governance ESG framework; target firm; stakeholder theory; resource-based view; acquirer; Sri Lanka; Sweden;

    Sammanfattning : Companies typically strive to expand their realms. To do so, they rely on a series of organic and non-organic growth options, the latter including Mergers and Acquisitions (M&As). M&As continue to grow in number and frequency across national and regional borders in search of strategic complementarity. LÄS MER

  3. 2. Real Time Navigation Algorithms for LEO Small Satellites using COTS GNSS

    Master-uppsats, KTH/Lantmäteri – fastighetsvetenskap och geodesi

    Författare :Nathan Groisne; [2023]
    Nyckelord :PNT; Small Satellite; COTS; GNSS; Navigation; ACS; PNT; små satelliter; COTS; GNSS; navigering; ACS;

    Sammanfattning : Many satellites in LEO use a GNSS-based navigation system, taking advantage of the GNSS constellations in MEO to enhance navigation capabilities. The thesis work focused on developing the software enabling GNSS-based navigation for Hemeria's future small satellites operating in LEO. LÄS MER

  4. 3. Design of an Array of Patch-elements With a Band-pass Frequency Selective Surface Hybrid Radome : Analysis and characterisation of a frequency selective surface and a phased array antenna

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Curt-Herman Normark Frisk; [2022]
    Nyckelord :Frequency Selective Surface; Microstrip Patch Element; Circular Polarisation; Phased Array Antenna; Single Feed; Frekvensselektiv Yta; Mikrostrip Patchelement; Cirkulär Polarisering; Fasstyrd Gruppantenn; Single-matad;

    Sammanfattning : A circular polarised phased array antenna and a frequency selective hybrid radome are designed and evaluated. The antenna system is well suited as a part of a communication link between platforms with a 600 MHz bandwidth and a centre frequency of 5 GHz. LÄS MER

  5. 4. Sensor fusion between positioning system and mixed reality

    Master-uppsats, Linköpings universitet/Tekniska fakulteten; Linköpings universitet/Institutionen för datavetenskap

    Författare :Anton Lifwergren; Jonsson Jonatan; [2022]
    Nyckelord :Sensor Fusion; MR; Mixed Reality; AR; Augmented Reality; Positioning; Local Positioning System; Transformation; Mining; Sensorfusion; MR; Mixed Reality; AR; Augmented Reality; Lokalt Positionerings System; Positionering; Transformation; Gruva;

    Sammanfattning : In situations where we want to use mixed reality systems over larger areas, it is necessary for these systems to maintain a correct orientation with respect to the real world. A solution for synchronizing the mixed reality and the real world over time is therefore essential to provide a good user experience. LÄS MER

  7. 5. Low-profile fully-metallic Luneburg lens antenna

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Justine Djounidi; [2022]
    Nyckelord :Beam Scanning; Luneburg Lens Antenna; Fully-metallic; Millimeter Wave; Vinkelskanning; Luneburg Linsantenn; Fullt Metalliskt; Millimetervåg;

    Sammanfattning : Modern communication systems face new technological challenges, such as the narrowness and overload of the conventional frequency bands employed for these applications. Nowadays, communication systems are expected to operate at higher frequencies, such as the mm-wave band. LÄS MER
