1. 21. Mescape - A probabilistic mesoscopic model for fire evacuation in large gatherings

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Lorenzo Contini; [2022]
   Keywords : Human behaviour; crowd evacuation; mesoscopic modelling; hydraulic model; large gatherings; fire safety; performance-based design; quantitative risk assessment; consequence analysis; uncertainty analysis; probabilistic modelling; Technology and Engineering;

   Abstract : This study presents a mesoscopic model that predicts pedestrian evacuation in large gatherings with probabilistic methods. The model is based on a coarse network representation of buildings, where occupants are treated at a different scale according to their location. READ MORE

3. 22. Groundwater Inflow into Fractured Rock Tunnels

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Mariam Beydoun; [2022]
   Keywords : groundwater inflow; rock tunnel; discrete fracture networks; discrete fracture-matrix; equivalent porous medium; Darcy’s Law; Reynold’s equation; cubic law; grundvatteninflöde; bergtunnel; discrete fracture networks; discrete fracture-matrix; equivalent porous medium; Darcy’s Law; Reynolds equation; cubic law;

   Abstract : Groundwater inflow is a challenge in construction of tunnels in fractured bedrocks since it affects the safety function of tunnels and leads to potential problems in the surrounding environment, such as subsidence, dropdown of the groundwater table. Quantification of groundwater inflow into the tunnel is also important for design of grouting in the construction of the tunnel. READ MORE

4. 23. Happy, risky assets: Uncertainty and (mis)trust in non-fungible token (NFT) conversations on Twitter

   University essay from Linnéuniversitetet/Institutionen för informatik (IK)

   Author : Sarah C.A. Meyns; [2022]
   Keywords : non-fungible token; NFT; concern; blockchain; Twitter; happy object; digital asset; topic modelling;

   Abstract : Background: Non-fungible token (NFT) trade has grown drastically over recent years. While scholarship on the technical aspects and potential applications of NFTs has been steadily increasing, less attention has been directed to the human perception of or attitudes toward this new type of digital asset; in particular, about potential concerns that users may have around the use of NFTs.

5. 24. Technologies and Evaluation Metrics for On-Board Over the Air Control

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Aneysha Datta; [2022]
   Keywords : Wireless; Performance Metrics; WAVE; DMG; Intra-Vehicular Communication; BER; Simulink; Model-Based Design;

   Abstract : This project has been carried out at the Electronic Embedded Systems Architecture Department at Volvo Construction Equipment (VCE), Eskilstuna, Sweden. It forms the baseline for a stepwise systematic research initiative to convert wired technologies used for certain in-vehicle control and communication components to wireless technologies. READ MORE

6. 25. Two-phase CFD Modelling and Validation : SH204X Master Thesis Project Report

   University essay from KTH/Kärnenergiteknik

   Author : Richard Härlin; [2022]
   Keywords : Master Thesis; Simulation; Validation; DEBORA; CFD; OpenFOAM; Boiling; Two-phase Thermal-Hydraulics; Fluid Mechanics; Nuclear Power Safety; Examensarbete; Simulering; Validering; DEBORA; CFD; OpenFOAM; Kokning; Tvåfas Termohydraulik; Kärnkraftssäkerhet;

   Abstract : This project deals with two-phase CFD model validation, a subject which is currently under active research due to its complexity. The goal is to create a model that predicts data profiles to an acceptable degree for a wide array of flow conditions. The applications within the nuclear field would mainly be for safety analysis, e.g. READ MORE
