  1. 1. Resistance of Polygonal Cross Sections of Lattice Wind Tower

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Bicen Jia; [2017]
    Keywords : polygonal cross section; wind tower;

    Abstract : Wind energy is one of the most efficient renewable energies. The most used wind towers are tubularand lattice wind towers. Parts of lattice are easier to transfer, especially in the inland areas. Also, it is easier to build higher lattice tower in order to have more efficient energy conversion in inland areas. READ MORE

  2. 2. Correction of Inhomogeneous Data in the Precipitation Time Series of Sweden Due to the Wind Shield Introduction

    University essay from Uppsala universitet/Luft-, vatten och landskapslära

    Author : Ioannis Sofokleous; [2016]
    Keywords : Precipitation data correction; precipitation time series; homogenization of precipitation data; wind shield; wind screen; aerodynamic wind error; Nederbördsdatakorrektion; nederbörds tidsserier; inhomogena nederbördsdata; vindskydd; vindskärm; aerodynamiska vindfel;

    Abstract : The work of this master thesis is based on analyses of monthly precipitation data from 70 stations of the SMHI (Swedish Meteorological and Hydrological Institute) in Sweden, in the period 1860-2014, using the information for the year of introduction of the wind shield at each station. The primary goal is the calculation of correction factors which will be applied on the precipitation data in the period of measurements before the introduction of the wind shield. READ MORE

  3. 3. The potential for centralized photovoltaicsystems in Sweden

    University essay from KTH/Hållbarhet och industriell dynamik; KTH/Hållbarhet och industriell dynamik

    Keywords : Grid-connected centralized PV systems; profitability PV farms; PV industry; large scale production; PV in Sweden; key factors; main challenges.;

    Abstract : Considering the long term target set by the Swedish government of having an energy system basedexclusively on renewable sources, the potential for different renewable sources need to beinvestigated. When analyzing the sources used for electricity production in Sweden today, solarPV represents a very small share. READ MORE

  4. 4. Methodology for preliminary design of high-rise buildings

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Stefan Svensson; Viktor Castlen Rist; [2016]
    Keywords : Komfortkrav; Göteborg city gate; Design; Egenfrekvens; Acceleration; Eurocode; Höga hus; Preliminär dimensionering; Arbetsmetodik; High-Rise; Building; Wind-induced acceleration; Preliminary Design; Gothenburg City Gate; Comfort Requirements; Methodology; Technology and Engineering;

    Abstract : The construction of high-rise buildings has previously been limited in Sweden. Changes in society in recent years, related to urbanisation, economics and architectural standards have however resulted in a greater interest for the construction of high-rise buildings. READ MORE

  5. 5. Modeling of temperature variations and response in a mining road bridge in Kiruna

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Mikael Fabricius; Henrik Ekman; [2016]

    Abstract : This thesis treats a concrete bridge located in Kiruna, in the north of Sweden, which was used for the mining industry. A finite element model has been created with the finite element software Abaqus to find out if it accurately can describe the variation of the temperature and deformation within the bridge over time.
