  1. 16. Petrography, alteration and structure of the Bronäs Zn-Pb-Ag deposits, Bergslagen, Sweden

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

    Author : Tom Turner; [2020]
    Keywords : Bronäs; Sala;

    Abstract : This report aims to characterize the alteration styles and mineralization of the Zn-Pb-Ag Bronäs deposit, in the Sala area of the Bergslagen mining district, Sweden.  It presents data collected through 237m of lithological logging and subsequent lithogeochemical data, which, coupled with thin section and SEM analysis has led to the first geological descriptions of the rocks in the deposit.

  3. 17. Smoothed Aggregation for Nonsymmetric Linear Systems

    University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematikcentrum

    Author : Siobhan Correnty; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : Smoothed Aggregation (SA) is a technique from algebraic multigrid methods (AMG) which has shown very promising results when solving systems of linear equations with symmetric system matrices, but suboptimal results for nonsymmetric system matrices. The purpose of this thesis is to investigate the method EMIN(r) and a closely related method EMIN proposed by Sala and Tuminaro. READ MORE

  4. 18. Single and multiple step forecasting of solar power production: applying and evaluating potential models

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Hugo Uppling; Adam Eriksson; [2019]
    Keywords : Forecasting; Gaussian process; ARIMA; ARIMAX; Solar power production;

    Abstract : The aim of this thesis is to apply and evaluate potential forecasting models for solar power production, based on data from a photovoltaic facility in Sala, Sweden. The thesis evaluates single step forecasting models as well as multiple step forecasting models, where the three compared models for single step forecasting are persistence, autoregressive integrated moving average (ARIMA) and ARIMAX.

  5. 19. Greenhouse Climate Optimization using Weather Forecasts and Machine Learning

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Victoria Sedig; Evelina Samuelsson; Nils Gumaelius; Andrea Lindgren; [2019]
    Keywords : machinelearning; predictions;

    Abstract : It is difficult for a small scaled local farmer to support him- or herself. In this investigation a program was devloped to help the small scaled farmer Janne from Sala to keep an energy efficient greenhouse. The program applied machine learning to make predictions of future temperatures in the greenhouse. READ MORE

  6. 20. Bredband som katalysator för gemenskap och kollektivt handlande : en studie om bredbandsutbyggnadens sociala påverkan på lokalsamhället

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

    Author : Oscar Kanzler; [2018]
    Keywords : Socialt kapital; tillit; kollektiv handling; lokalsamhälle; byalag; lokal gemenskap; nätverk; bredband;

    Abstract : Där ett kommersiellt eller kommunalt intresse för bredbandsutbyggnad saknas måste invånarna på landsbygden organisera sig om de önskar tillgång till en fiberanslutning. Detta kräver ett samarbete och tillit mellan invånarna för att lyckas driva ett bredbandsprojekt på egen hand. READ MORE
