  1. 21. SARIMAX tillförlitlighet vid prediktion av fjärrvärmeförbrukning : En experimentell studie

    Kandidat-uppsats,

    Författare :Abdullaahi Mohamed; Ajdin Zekan; Alexander Eriksson; [2020]
    Nyckelord :SARIMA; SARIMAX; Prophet; district heating; prediction; time series analysis; SARIMA; SARIMAX; Prophet; fjärrvärme; prediktion; tidsserieanalys;

    Sammanfattning : Huvudsyftet med denna studie är att förstå om ett säsongsmässigt autoregressivt integrerat rörligt genomsnitt (SARIMA) -metod pålitligt kan förutsäga extrem variation i värmelaster för en fjärrvärmestation. Genom extrem variation ser vi på den maximala och minsta värmebelastningen per dag mätt i megawattstimmar. LÄS MER

  3. 22. Crowd evacuation in high-density scenarios

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Ines Cilenti; [2019]
    Nyckelord :Crowd evacuation; high-density; crowd pressure; video analysis; bottleneck; outdoor event; local density.; Technology and Engineering;

    Sammanfattning : Nowadays, is becoming increasingly frequent holding events in outdoor environments, involving a large number of people, even though these spaces were not designed from a safe prospective, in the way that safety is defined today. In such events, high density conditions is an ongoing issue, as the evacuation becomes very complex, due to the space design and the interaction among the pedestrians. LÄS MER

  4. 23. Electrical power demand forecasting

    Kandidat-uppsats,

    Författare :David Weinberg; [2019]
    Nyckelord :;

    Sammanfattning : The electrical load, sampled every hour, at Salagatan 18 in Uppsala was used to form models and for forecasting the load. It was investigated whether Multi Seasonal ARIMA models and Support Vector Regression were suitable. The models were compared to a naive persistence benchmark in periods of high and low volatility.

  5. 24. Multiple Time Series Forecasting of Cellular Network Traffic

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Emma Wallentinsson Wallentinsson; [2019]
    Nyckelord :time series analysis; cellular networks; traffic load; arima; sarima; forecasting; machine learning; statistics; load prediction;

    Sammanfattning : The mobile traffic in cellular networks is increasing in a steady rate as we go intoa future where we are connected to the internet practically all the time in one wayor another. To map the mobile traffic and the volume pressure on the base stationduring different time periods, it is useful to have the ability to predict the trafficvolumes within cellular networks. LÄS MER

  7. 25. Elektrifiering av personbilar på Tomtebo, Umeå : Electrifications of passenger cars at Tomtebo, Umeå

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Victor Andersson; [2019]
    Nyckelord :Elektrifiering; personbilar; Umeå; Tomtebo;

    Sammanfattning : In the future, new fuels will be sought to minimize the carbon footprint on Earth. With electric vehicles becoming a growing trend there is an annual increase in hybrid and electric cars, even electrified buses have become more convenient. LÄS MER
