  1. 21. ELECTRIFICATION OF THE SWEDISH VEHICLE FLEET: CHARGING DEMAND AND THE POWER SYSTEM

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Edward Hsuan-Wei Hsu; [2021]
    Keywords : Electric vehicle; Electrification; Sweden; energy system; energy consumption; power capacity; sustainability; passenger vehicle; truck; bus;

    Abstract : With the transport sector switching to electric energy to reduce greenhouse gas emission, the supply and demand in the energy system are impacted by this transition. Meanwhile, there are not a lot of studies focus on the electrification of the vehicle fleet in Sweden. READ MORE

  3. 22. Impact of different primary particles on Geant4 simulation execution time - study on protons and pions

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Rebecca Jigström Madeira; [2021]
    Keywords : Geant4; Monte Carlo method; Large Hadron Collider; simulation time; collider experiment; Physics and Astronomy;

    Abstract : The High Luminosity Large Hadron Collider (HL-LHC) at CERN, an improvement to the LHC, scheduled to be operating in 2027, will further the potential for scientific breakthroughs in High Energy Physics. The project’s demand in computational resources, however, is predicted to exceed what will be available then. READ MORE

  4. 23. The Causes for Cost Overruns in Infrastructure Projects

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Yuan Tan; [2021]
    Keywords : Cost overrun; Cost estimation; Project management; Case study;

    Abstract : This thesis analyzes the underlying reasons for cost overruns in Trackside signalling projects at Bombardier Transportation focusing specifically on man-hours. Despite the increasing public, political and academic interest in the issue of cost overruns in infrastructure projects during the past decades, limitations related to data access have made it difficult to shed light on the prevalence and causes of cost overruns.

  5. 24. A photodegradation study of conjugated polymers for organic solar cells by absorption spectroscopy and atomic force microscopy

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Johansson André; [2021]
    Keywords : OSC; solar cells; active layer; polymer; degradation;

    Abstract : The effect of light exposure in ambient air on thin films made from an electron acceptor polymer poly{[N,N'-bis(2-octyldodecyl)naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]-alt-5,5'-(2,2'-bithiophene)} (N2200), an electron donor polymer Poly[[2,3-bis(3-octyloxyphenyl)-5,8-quinoxalinediyl]-2,5-thiophenediyl] (TQ1) and their blends, has been studied using UV-vis spectroscopy and Atomic Force Microscopy (AFM). For solutions of TQ1, N2200 and blends, the linearity of the Beer-Lambert law for absorption spectroscopy has been verified. READ MORE

  6. 25. Impact of light quality on leafy green vegetables

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Muhammad Abdul Aziz; [2021]
    Keywords : blue light; controlled light; E. coli; spinach;

    Abstract : Fruits and vegetables are a vital part of the human diet, and their consumption is on the rise because they are considered as a healthy intake. However, ingredients of fruits and vegetables are vulnerable in postharvest handling like moisture loss, wrong handling, physical damage, and microbial contamination. READ MORE
