  1. 16. A study of the effects of winterclimate and atmospheric icing onhigh-speed passenger trains

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Markus Granlöf; [2020]
    Keywords : Survival analysis; continuous Markov model; cumulative delay; highspeed train; weather; atmospheric icing;

    Abstract : Harsh winter climate causes various problems for both the public andprivate sector in Sweden, especially in the northern part and the railway industryis no exception. This master thesis project covers an investigation of the eects ofthe winter climate and a phenomena called atmospheric icing on the performance ofthe train in a region called the Botnia-Atlantica region.

  3. 17. Maglev deployment in winter climate

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Axel Thorstrand; [2020]
    Keywords : ;

    Abstract : As of year 2020, maglev train systems are not in service in areas with harsh winter climate. Compared to conventional railway, the technology is relatively new and untested in conditions of low temperatures, icing and snow. READ MORE

  4. 18. Vägsaltets påverkan på närliggande vegetation, mark samt närliggande slitlager

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

    Author : Jakob Frängsmyr; Stina Nilsson; [2020]
    Keywords : vägsalt; struktur; halkbekämpning; jord; lignoser; påverkan;

    Abstract : Syftet med detta arbete är att göra en litteraturstudie och sammanställa fakta om hur vägsalt (NaCl, natriumklorid) påverkar vår stadsmiljö samt att få en överblick hur vegetation, slitlager och markytor i närheten av saltbehandlade vägar påverkas av den höga saltningsintensiteten. I arbetet ingår också en kartläggning av vilka andra alternativ och metoder till salt som provats för att eventuellt kunna vara likvärdiga eller bättre i sin funktion och inte vara lika skadliga som salt är för miljön.

  5. 19. Defining, analyzing and determining power losses - due to icing on wind turbine blades

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Zandra Canovas Lotthagen; [2020]
    Keywords : Wind Power; De-icing; Defining; Ice losses; Task19; Temperature threshold; Power curve; Big Data;

    Abstract : The wind power industry is one of the fastest-growing renewable energy industries in the world. Since more energy can be extracted from wind when the density is higher, a lot of the investments made in the wind power industry are made in cold climates. But with cold climates come harsh weather conditions such as icing. READ MORE

  6. 20. Effects of Salinization on Lake Metabolism

    University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Author : Emil Nordström; [2020]
    Keywords : Freshwater ecology; carbon flux; mesocosms; diurnal variation;

    Abstract : With rising salinity levels in many freshwaters across the globe caused by for example sealevel rise and de-icing salts, it becomes important to understand what effect it has on freshwater ecosystems, since the lakes and rivers themselves are important parts in the global carbon cycle. In this study I have looked at what effects increased salinity levels have on different lakes metabolism, specifically oxygen concentration and primary production. READ MORE
