  1. 16. Beam-steered Modulation in Advanced Antenna System

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Smitha Jinnahalli Venugopal; [2023]
    Keywords : 5G-MIMO; Beam-forming; Beam-steering; Advanced antenna systems; Technology and Engineering;

    Abstract : The newer spectral bands in millimeter-wave (mm-Wave) spectrum over the last few years have made higher data rates possible and improved quality of service for the users, but it possesses new challenges to design spectral agile radios. Power Amplifiers (PA) are a crucial analog component connected to Multiple input multiple output (MIMO) antennas which inherits non-linear effects. READ MORE

  3. 17. Coincidence Factor and Battery Energy Storage Systems for Industrial Electrical Power Supply : A Field Study of Building 178 at Scania AB, Södertälje

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Lucas Wallhager; [2023]
    Keywords : Coincidence factor; Industrial electric load diversity; Velander; Normal distribution; Herman-Beta; Battery energy storage system; Sammanlagringsfaktor; Industriell elförbrukning; Velander; Herman-Beta; Batterier för energilagring;

    Abstract : Coincidence factors have been researched since the late 1800s, as they displays the ratio between the maximum coincidencental power usage of a system, and the sum of the maximum individual loads of the system. Accurate estimations of the highest coincidental power usage allow for minimal material usage when constructing substations, transformers, overhead lines, and cables for power transmission.

  4. 18. Lateral Stabilization of CLT Buildings - Modelling approaches

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Lina Holmqvist; Sanna Källman Gleisner; [2022]
    Keywords : Technology and Engineering;

    Abstract : Cross-laminated timber (CLT) is an environmentally positive building material with high stiffness and load-bearing capacity. In combination with a low self-weight, CLT is a beneficial material to use for the load-bearing structure of high-rise buildings. READ MORE

  5. 19. Semi-Automatic calculation of the stability of shear walls in multi-storey buildings

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Erik Bolin; Emil Sjöstedt; [2022]
    Keywords : Horizontal stabilisation; Dynamo; Shear walls; Stability; Conceptual design phase; Visual programming; Openings in shear walls; Load distribution; Relative stiffness; Technology and Engineering;

    Abstract : Performing horizontal stability analysis in the conceptual design phase is time consuming and adjustments in the geometry of the building require new time consuming calculations. Often buildings are modelled in 3D modelling software such as Revit and Tekla but the calculations are often performed in a separate software. READ MORE

  6. 20. Evaluation of Coefficient of Friction in Oblique Helmet Impacts: An Experimental and Numerical Study

    University essay from KTH/Hållfasthetslära

    Author : Philip Singh; [2022]
    Keywords : FE model; friction; helmet impact; LS-DYNA; FE-modell; friktion; hjälmislag; LS-DYNA;

    Abstract : The focus of this thesis was to increase the knowledge in the area of "dynamic friction" during oblique helmet impacts, both experimentally and numerically. Physical experiments have been performed with multiple helmets, different angles of the anvil and different surface materials, with results of impact forces from the anvil and accelerations of the head.
