  1. 1. Skalningseffekter av medelstora pölbränder i syrereducerad miljö

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Tim Hemel; Philip Frenander; [2024]
    Nyckelord :Sökord: syrereducerad atmosfär; medelstora pölbränder; skalningseffekter. Key words: hypoxic air; oxygen reduced atmosphere; medium pool fire; scaling effects; LOC; yields.; Technology and Engineering;

    Sammanfattning : This bachelor's thesis focuses on how scaling the pool diameter affects flammable liquids in an oxygen reduction system (ORS). This topic in the study of pool fire behavior in hypoxic air has been only lightly discussed in previous literature. Therefore, the goal of this thesis work is to further broaden the understanding of hypoxic air. LÄS MER

  3. 2. Stadsträd – i nöd och lust : skillnader i reglerande och stödjande ekosystemtjänster mellan löv- och barrträd i stadsmiljö

    Kandidat-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Jennifer Engelbrekt Tchang; Sara Karlsson; [2023]
    Nyckelord :ekosystemtjänst; lövträd; barrträd; stadsträd; luftrening; dagvattenhantering; vindskydd; temperaturreglering; kolupptagning; kolinlagring; biologisk mångfald;

    Sammanfattning : Träd har en viktig roll i att klimatanpassa städer genom att leverera ekosystemtjänster. I nordiska städer planteras mest lövträd eftersom det historiskt funnits ett kulturellt motstånd mot barrträd. LÄS MER

  4. 3. Environmental factors affecting European spruce bark beetle (Ips typographus) outbreaks in Sweden : Linking AI-detected dead spruce, soil moisture, nature protection and bark beetle outbreak (Ips typographus) in Sweden

    Master-uppsats, Karlstads universitet

    Författare :Petter Hessle; [2023]
    Nyckelord :Ips typographus; Biology; forest; Norway spruce; Picea abies; European spruce bark beetle; Ecology; outbreak; Ai; Sweden; Biologi; ekologi; skog; Granbarkborre; gran; Ai; utbrott; naturvård; Ips typographus; sverige;

    Sammanfattning : Norway spruce (Picea abies) is a vital tree species in Sweden's extensive forested landscape. However, the planting of spruce beyond its natural range has made it vulnerable to pests like the spruce bark beetle (Ips typographus), which has caused substantial damage to Swedish forests.

  5. 4. Evaluation of the DXA radiation environment at Sahlgrenska University Hospital

    Master-uppsats,

    Författare :Saga Söderholm; [2022-05-18]
    Nyckelord :Medical physics; DXA; DEXA; Dual-energy X-ray absorptiometry; Bone mineral density;

    Sammanfattning : Purpose: The aims of this work were to evaluate the radiation environment in the dual-energy X-ray absorptiometry (DXA) rooms at Sahlgrenska University Hospital, estimate personnel doses, determine legal requirements for DXA personnel, examine the operators’ view on radiation safety and develop material with dose information for patients and operators. Theory: DXA is a low dose X-ray modality mainly used in osteoporosis examinations, for which it is considered the reference technique. LÄS MER

  7. 5. Mitigating HTTP Denial-of-Service Attacks on Self-Hosted Web Applications

    Kandidat-uppsats, KTH/Datavetenskap

    Författare :William Berg; Gustav Henningsson; [2022]
    Nyckelord :;

    Sammanfattning : Denial-of-service (DoS) attacks are a common threat to any resource on the internet, making knowledge regarding how to prevent them increasingly valuable. In this paper we have investigated different HTTP DoS attacks, how they affect web servers, and what steps one might take to protect a self-hosted web application from such attacks. LÄS MER
