  1. 21. Experimental Study of Installation Effects on Cooling Fan Noise

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Yu-Yu Lu; [2021]
    Keywords : Electric vehicles; Cooling fan noise; Installation effects; Free-space measurement; Wall-mounted measurement; In-vehicle measurement; Spectral decomposition method; Tonality; Broadband noise level.;

    Abstract : Owing to the ever-changing developments of battery and electric powertrain, vehicle electrification is the trend in the future. Without the presence of a combustion engine, masking effect from it reduces and noises from other components become perceivable. Among all, the cooling fan is one of the major noise sources.

  2. 22. Parametric Studies of Train-Track-Bridge Interaction : An evaluation of the dynamic amplification due to track irregularities for freight transport

    University essay from KTH/Bro- och stålbyggnad

    Author : Rasmus Elm Dahlman; Emil Lundberg; [2021]
    Keywords : Dynamics; dynamic amplification factor; railway bridge; train-track-bridge interaction; vehicle model; track irregularities; PSD; Dynamisk förstoringsfaktor; dynamik; järnvägsbroar; tåg-spår-bro interaktion; fordonsmodell; spårojämnheter; PSD;

    Abstract : In this thesis a train-track-bridge interaction (TTBI) model is developed in order to study the dynamic amplification from track irregularities on railway bridges traversed by freight trains. These simulations are of great importance since rail freight transport is expected to increase in order to meet the climate goals. READ MORE

  3. 23. Embellishment or declaration? A single case study on constructing a responsible image towards stakeholders through sustainability reporting

    University essay from Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

    Author : Qiyue Wang; Qi Qi; [2021]
    Keywords : Sustainability reporting; Rhetorical strategies; Organizational façades; Fast-fashion industry; Stakeholder engagement;

    Abstract : The thesis exams how an international company conveys its business operations through sustainability reporting. Drawing on Brennan & Merkl-Davies (2014)'s rhetorical strategies in social and environmental reporting as well as Cho et al. READ MORE

  4. 24. Towards a high resolution view of infrared line formation

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Martin Schmidt Montelius; [2021]
    Keywords : Spectroscopy; Near infrared; K giants; Galactic archeaology; Galactic chemical evolution; Abundances; Milky Way; Physics and Astronomy;

    Abstract : Observing in the infrared has many benefits, such as seeing through the interstellar dust in the galaxy, easier use of adaptive optics, and better flux ratios for direct observations of exoplanets. Before the infrared spectral range can be utilised for highly accurate stellar spectroscopy there is a need for a better understanding of both stellar modelling and the atomic physics that go into forming spectral lines.

  5. 25. Study of Kinematic Variables in Multi-Lepton Final States in search for an Exotic Higgs Boson

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Axel Gallén; [2021]
    Keywords : LHC; ATLAS; CERN; Standard Model; Higgs boson; Exotic Higgs boson; Kinematic variables; Physics and Astronomy;

    Abstract : The Large Hadron Collider in Geneva was constructed as a discovery machine. So far, the Higgs boson has been the only discovery at the Large Hadron Collider, but physicists keep on pushing the limit in order to discover new particles. READ MORE
