  1. 16. Energy Usage in Railway Wayside Object Heating : Modeling of melting of Ice, Estimation of heating power requirement in Switch and Renewable energy feasibility for a Railway system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Sidharth Kapoor; [2022]
    Keywords : Melting of Ice; Numerical modeling; Transient conjugate heat transfer; Transient analysis; CFD; Switch heating; Heat pumps in Railways; Issmältning; Numerisk modellering; Transient värmeöverföring; Transientanalys; CFD; Värmepumpar i järnvägar;

    Abstract : Trafikverket operates about 12000 Switches and crossings (SnCs) of which 6800 are equipped with an electrical heating system of 10−30kW power to keep SnCs functional throughout the winters by keeping them free of Snow/Ice. The energy consumption is approximately 200−130GWh/year costing approximately 10−15 million Euros annually. READ MORE

  3. 17. Real-time Snow Simulator using Iterative-relaxation and Boundary Handling

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Adrian Nordin; Simon Nylén; [2021]
    Keywords : Snow; Real-time Simulation; Iterative Method; Two-way Coupling; Computer Graphics;

    Abstract : Background Physics-based snow simulation in real time is an unexplored area, the reason being the difficulty introduced by the multitude of factors that affect the snow behaviour, such as cohesion, thermodynamics, and compression. Simulating snow in real time when considering these factors can become computationally demanding. READ MORE

  4. 18. Practical evaluation of the viability of sensorsand algorithms to detect falling and burial by avalanche

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Justus Conradi; Patrik Tiainen; [2021]
    Keywords : Mechatronics; Master thesis; fall detection; burial detection; avalanche; skiing; IMU; FSR; Mekatronik; mastersavhandling; fallavkänning; begravningsavkänning; lavin; skidåkning; IMU; FSR;

    Abstract : Avalanches kill on average 250 people per year. Fall detection algorithms have been used to detect many different types of falls. In this work, a robust humanoid test rigwas designed and built to investigate the use of proven threshold based fall detection algorithms during skiing. READ MORE

  5. 19. Slab and Powder-Snow avalanche animation on the GPU

    University essay from Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

    Author : Åleskog Jonthan; Cheh Daniel; [2021]
    Keywords : Avalanche; GPU; DEM; Real-time; Games; Lavin; GPU; DEM; Realtid; Spel;

    Abstract : Background: The video game industry has yet to achieve a physically-based real-time avalanche simulation because of the sheer complexity of modeling the behavior of snow avalanches. An avalanche is made out of snow, meaning it would require a snow simulation which itself already shows to be complex. READ MORE

  6. 20. Gestaltning för friluftsliv året runt : ett gestaltningsförslag på Holmön för att stärka friluftslivet på vintern

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Lisa Johansson; [2021]
    Keywords : friluftsliv; rekreation; vinter; Holmön; klimatanpassad design;

    Abstract : Friluftsliv har länge ansetts om en fördelaktig metod för att öka fysisk aktivitet och skapa naturkontakt resulterande i ökad livskvalitet (Emmelin et al. 2010). Under vinterperioden minskar dock denna utomhusaktivitet drastiskt. READ MORE
