  1. 11. Quantum chemical studies of the reactivity of gold nanoparticles towards molecular radicals

    Master-uppsats, KTH/Kemi

    Författare :Sofia Larsson; [2022]
    Nyckelord :gold nanoparticles; surface electrostatic potential; average local ionization energy; electron attachment energy; free molecular radicals; guldnanopartiklar; elektrostatisk ytpotential; genomsnittlig lokal joniseringsenergi; fria molekylära radikaler;

    Sammanfattning : Kvantkemiska studier av reaktiviteten hos guldnanopartiklar Au3-Au11 och Au13 mot O- centrerade molekylradikaler OH , OOH , OCH3   och H2O undersöks. Olika molekylära ytegenskaper tas med i beräkningen, elektrostatiska ytpotentialen, den genomsnittliga lokala joniseringsenergin, electron attachment energy och spinndensiteten (VS(r), IS(r), TS(r), ES(r) och S(r)).

  3. 12. Supply chain attacks in open source projects

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Oliver Stussi; David Uhler Brand; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The space of open source supply chain attacks is ever evolving and growing. There is extensive previous work identifying and collecting open source supply chain attacks, as well as identifying patterns in these attacks and proving that machine learning models may be able to detect these patterns.

  4. 13. The self-exciting Hawkes processand dynamic contagion

    Master-uppsats, Uppsala universitet/Sannolikhetsteori och kombinatorik

    Författare :Isak Dahlqvist; [2022]
    Nyckelord :;

    Sammanfattning : We introduce the necessary theory to construct self-exciting processes, particularly random and Poisson measures. Our goal is to show how to work with and analyze self-exciting processes. We consider a Hawkes process with the exponential kernel, a counting process with an intensity that depends on the process itself. LÄS MER

  5. 14. Cluster Initiative Success Management – a single case study on Telematics Valley

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Emma Åström; Saima Shahid; [2021-07-06]
    Nyckelord :Telematics; Telematics Valley; Clusters; Cluster Initiative; Regional Innovation Systems RIS ;

    Sammanfattning : Regional Innovation System (RIS) and clusters have long been argued for having a positive impact on regional growth. Also, the eminence of cluster initiatives and how in turn they support regional growth and development are becoming important questions for scholars and practitioners as well. LÄS MER

  7. 15. Identifying factors that correlate with Enhanced Biological Phosphorus Removal upsets at Lundåkraverket

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Rounak Niranjan; [2021]
    Nyckelord :Enhanced biological phosphorus removal; polyphosphate accumulating organisms; glycogen accumulating organisms; sludge content in aeration basin; nitrates in aeration basin; pH of incoming water; principal component analysis; pairwise correlations; inhibition factors;

    Sammanfattning : The Enhanced Biological Phosphorus Removal (EBPR) process is characterized as the most sustainable process to remove phosphorus from wastewater albeit with high variability in performance efficiency. Thus, unpredictable upsets in the EBPR system is the norm across several wastewater treatment plants throughout Sweden, forcing the hand of the operators to dose higher volume of chemicals to reach the effluent requirements.
