  1. 1. Methods and Purposes of Aerodynamic Correlation in Formula Student

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Alix Le Bastard; [2023]
    Keywords : Technology and Engineering;

    Abstract : This thesis investigates how methods of aerodynamic validation can assist a formula student team in designing their aerodynamic package. When de- signing their aerodynamic components, formula student team mostly rely on CFD software simulations, but there is no guarantee that the simulations de- pict properly the physical behaviour of the airflow around the car.

  3. 2. Air quality prediction in metropolitan areas using deep learning methods

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Augustin Ionut Ionascu; [2023]
    Keywords : air quality; forecasting; time-series; univariate; multivariate; multi-step; Attention; Transformer;

    Abstract : The rapid growth of the world's urban population shows that people are increasingly moving to cities. In recent decades, the frequent occurrence of smog caused by increasing industrialization has brought environmental pollution to record highs. READ MORE

  4. 3. Simulation and Testing of a MU-MIMO Beamforming System

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

    Author : Nazyar Mehdishishavan; Zonghan Wang; [2023]
    Keywords : Multi-User Multiple-Input Multiple-Output MU-MIMO ; Beamforming; Sounding Reference Signal SRS ; Reciprocity-based; Butler matrix; Advanced Antenna System AAS ; Technology and Engineering;

    Abstract : Multi-User Multiple-Input Multiple-Output (MU-MIMO) technology has become increasingly important in the field of wireless communication due to its ability to highly increase the capacity and efficiency of wireless networks [1]. Beamforming, as a technique used in MU-MIMO systems, improves network performance by improving signal quality and reducing interference. READ MORE

  5. 4. Investigation on Enhancing Fire Threat Perception in Virtual Reality through Subject-Expectancy Effect

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Hsuan-Ting Liu; [2023]
    Keywords : Virtual reality; safe distance; subject-expectancy effect; thermal radiation; placebo effect; fire scenario.; Technology and Engineering;

    Abstract : This thesis examines the use of subject-expectancy effect on enhancing fire threat perception in virtual reality. The study involves a virtual fire scenario design and 33 participants who experience virtual fires of three different scales in the scenario using a head-mounted display as visual and auditory perception and adopting physical movement in real world as their way of locomotion.

  6. 5. Evaluating the performance of cone crushers under various feeding conditions using DEM and coupled DEM-MBS simulations

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : John Larsson; [2023]
    Keywords : Discrete Element Method; DEM; Cone Crusher; Segregation; Co-Simulation; Multi-body Dynamics; MBD;

    Abstract : Cone crushers are used in both the construction and mining industries for the production of aggregates and extraction of ores. Aggregates are used when building for example houses, roads and railways, hence the cone crushers are a vital part of modern society. READ MORE
