    Sammanfattning : Organic solar cells (OSCs) based on non-fullerene acceptors (NFAs) have attracted a great deal of attention in recent years due to their rapidly increasing efficiency and enormous potential. In this work, the optical and electronic properties of systems containing the very promising non-fullerene acceptor PYT have been thoroughly studied with the use of the density functional theory (DFT) and the time-dependent density functional theory (TDDFT).

  3. 2. "Nu är det skol- och kyrkbråk igen!" : en fallstudie av privatpersoners inlägg i debatten om skolavslutning i kyrkan 2010-2012

    Kandidat-uppsats, Uppsala universitet/Teologiska institutionen

    Författare :Rickard Svensson; [2021]
    Nyckelord :End of year ceremony; Church of Sweden; Vicarious religion; Public debate; Public utility;

    Sammanfattning : Sweden and its relationship with the former state church Church of Sweden and religion, is complicated. The country has been described as one of the most secular countries in the world, and yet one of the longer recurring public debates has been on the topic of whether schools’ end of year ceremonies should take place in local churches or not.

  4. 3. Waste i en orderhanteringsprocess : en fallstudie vid ett grossistföretags webblager

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för ekonomistyrning och logistik (ELO)

    Författare :Max Jakobsson; Rickard Gustavsson; Mattias Svensson; [2018]
    Nyckelord :waste; webblager; grossistföretag; e-handel;

    Sammanfattning : Bakgrund: Konkurrensen om kunder ökar allt mer inom e-handeln. Inom grossistföretag är lagerverksamheten den viktigaste komponenten för en framgångsrik verksamhet och detta blir allt viktigare då e-handeln expanderar. För att driva en effektiv lagerverksamhet bör företag identifiera och eliminera waste. Frågeställningar:1. LÄS MER

  5. 4. Analysis of machine learning for human motion pattern  recognition on embedded devices

    Master-uppsats, KTH/Mekatronik

    Författare :Tomas Fredriksson; Rickard Svensson; [2018]
    Nyckelord :ai; machine learning; embedded systems; internet of things; human motion analysis; support vector machines; decision tree; random forest; features; cortex m-series; ai; maskininlärning; inbyggda system; internet of things; människliga rörelser; support vector machines; decision tree; random forest; features; cortex m-series;

    Sammanfattning : With an increased amount of connected devices and the recent surge of artificial intelligence, the two technologies need more attention to fully bloom as a useful tool for creating new and exciting products. As machine learning traditionally is implemented on computers and online servers this thesis explores the possibility to extend machine learning to an embedded environment. LÄS MER

  7. 5. Methodology for analysis of traffic-induced building vibrations

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Rickard Torndahl; Tobias Svensson; [2017]
    Nyckelord :infinite elements; soil dynamics; structural dynamics; wave propagation; dynamic reduction; traffic-induced vibration; finite element method; building vibration; structural design; Technology and Engineering;

    Sammanfattning : Urban population growth leads to denser cities where buildings are being constructed closer to sources of vibration like motorways, railways and tramways. The risk of disturbing vibrations is thereby increasing which could affect residents and sensitive equipment, for instance equipment used in hospitals. LÄS MER
