  1. 16. Petrography and Thermodynamic Modelling of Svecofennian Arsenic-bearing Metasupracrustal Rocks in the Arlanda Area, West-Central Fennoscandian Shield

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Klara Skoog; [2022]
    Keywords : Bergslagen; Svecokarelian orogeny; metamorphism; arsenic; optical microscopy; electron microprobe; thermodynamic modelling; Bergslagen; Svecokarelska orogenesen; metamorfos; arsenik; optisk mikroskopering; elektron mikrosond; termodynamisk modellering;

    Abstract : The Arlanda area is a construction intensive area facing problems with risk of leaching of arsenic (As) from the bedrock to surface- and groundwater. Construction projects in the area have had problems with high levels of As in the bedrock and the risk of leaching increases through processing of aggregates and blasting of the bedrock. READ MORE

  3. 17. Lärdomar från den forntida ökenstaden Petras dagvattenhanteringssystem

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Emelie Jonsson; [2022]
    Keywords : dagvattenhanteringssystem; rörsystem; dagvatten; torka; översvämning; Nabaté; wadi; vattenhanteringsstrategi;

    Abstract : Enligt SMHI kommer Sverige att utsättas för mer extrema perioder av torka och mer frekventa översvämningar på grund av högre, i genomsnitt, årliga temperaturer. Svenska dagvattensystem är redan idag känsliga för dessa väderfenomen (SMHI,2021). READ MORE

  4. 18. Buckling of Short End-Bearing Piles in Clay

    University essay from KTH/Jord- och bergmekanik

    Author : David Ebenhardt; Jonas Stener; [2022]
    Keywords : Short piles; buckling; elastic buckling length; initial deflection; finite element method; Eurocode 3;

    Abstract : Structural design of piles with respect to buckling in Sweden is commonlymade in accordance with the calculation model from the Commission ofPile Research, PKR. A prerequisite for this model is that the elasticbuckling length of the pile is shorter than the physical length. READ MORE

  5. 19. 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

  6. 20. Analysis of Modelling 3D Bedrock Surfaces using Interpolation Methods : A Comparison between Models of 3D Bedrock Surfaces using Different Interpolation Methods

    University essay from KTH/Geodesi och satellitpositionering

    Author : Mario Marrugat Rodríguez; [2022]
    Keywords : GEOBIM; 3D-ytor; Civil 3D; ArcGIS; Berggrund; Osäkerheter;

    Abstract : Geological and geotechnical studies are a critical component of most projects, and it has a significant impact on the economy, project timelines, and subsequent project design. Today, the development of GEOBIM eases this analysis, thus saving costs, speeding up processes and avoiding risks. READ MORE
