  1. 21. Heterogeneous catalytic reactions studied with transient gas supply and event-averaged ambient pressure x-ray photoelectron spectroscopy

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for Nanoscience

    Författare :Qianhui Liu; [2022]
    Nyckelord :Ambient pressure x-ray photoelectron spectroscopy; Event-averaging; Pd 100 surface structure oscillation; Physics and Astronomy;

    Sammanfattning : CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially.

  3. 22. Far-field pattern synthesis of transmitarray antennas using convex optimization techniques

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Marie Defives; [2022]
    Nyckelord :Applied physics; Transmitarray antennas; convex optimization; Tillämpad fysik; Transmitarray-antenner; konvex optimering;

    Sammanfattning : Transmitarrays antennas (TAs) can be seen as the planar counterpart of optical lenses. They are composed of thin radiating elements (unit cells) which introduce different local phase shifts on an incident electromagnetic wave, emitted by a primary source, and re-radiate it. LÄS MER

  4. 23. Stress inom svenska medier : En kvantitativ studie om svenska nyhetsreportrars upplevelser av stress

    Kandidat-uppsats, Karlstads universitet/Institutionen för sociala och psykologiska studier (from 2013)

    Författare :Jennie Segerström; [2022]
    Nyckelord :stress in the journalistic force; reflexive modernity; juggernaut; social acceleration; modernity; self-identity; resonance; alienation; stress inom journalistyrket; reflexiv modernitet; juggernaut; social acceleration; modernitet; självidentitet; resonans; alienation;

    Sammanfattning : Bakgrund: Statistik visar på att allt fler i Sveriges befolkning upplever en ökad stress i så väl privat- som yrkesliv. Detta yttrar sig till exempel inom områden där digitaliseringen är avhängig för en fortsatt relevans på arbetsmarknaden och inom yrkesgrupper som redan tidigare haft höga krav på kunskap, effektivitet och hastighet.

  5. 24. Ramp-up of a new production system, organisation, and product : Towards an integrated model

    Master-uppsats, Jönköping University/JTH, Produktionsutveckling

    Författare :Filip Norresjö; Philip Karlsson; [2022]
    Nyckelord :;

    Sammanfattning : In today’s global competition, product lifecycles become shorter and new products are released at the market in a rapid pace. A successful ramp-up is vital to reach the target production capacity on time and create a competitive advantage. The complexity of a ramp-up increases with the number of novel factors. LÄS MER

  7. 25. Path planning algorithm for levitating planar motion system

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Henry Nilsson; Johan Ternerot; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In today’s world of ever increasing competitiveness, solutions that include automation and smart production have become a vital part to consider in overall business strategy, specifically for the industry sector. Whether an automated production process will be beneficial or not is dictated by how sub-processes such as interproduction transportation operates. LÄS MER
