  2. 1. Upflow anaerobic sludge blanket reactor : modelling

    Author : Raul Rodriguez; Luis Moreno; Olle Wahlberg; Gunno Renman; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; wastewater; anaerobic treatment; modelling; UASB reactor.; Chemistry; Kemi;

    Abstract : Anaerobic treatment is widely used around the world as a biological stage in both domestic and industrial wastewater-treatment plants. The two principal advantages of anaerobic over aerobic treatment are the production of biogas, which can be used as fuel, and the lower rate of biomass production, which results in lower maintenance costs for the plant.

  4. 2. Modelling Sexual Interactions : Sexual behaviour and the spread of sexually transmitted infections on dynamic networks

    Author : Disa Hansson; Tom Britton; Fredrik Liljeros; KaYin Leung; Janneke Heijne; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical modelling; Sexually transmitted infections; Egocentric network analysis; Dynamic networks; Sexual behaviour; HIV; Statistical inference; Mathematical Statistics; matematisk statistik;

    Abstract : In this thesis we develop statistical and mathematical models to study different factors of relevance for the spread of sexually transmitted infections (STIs). Two special interest groups for STI interventions are considered: sexually active youths and men who have sex with men (MSM). READ MORE

  5. 3. Plastic behaviour of steel : experimental investigation and modelling

    Author : Jonas Gozzi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : This thesis deals with the plastic behaviour of steel. It comprises an investigation with focus on biaxial tests and constitutive modelling. Tests were performed on one stainless steel grade in two different strength classes, C700 and C850, as well as one extra high strength structural steel grade. READ MORE

  6. 4. Defects and Surfaces and their Impact on Fatigue Behaviour of Powder Bed Fused Ti-6Al-4V : Characteristics and Modelling

    Author : Viktor Sandell; Marta-Lena Antti; Pia Åkerfeldt; Thomas Hansson; Stefano Beretta; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Defects; Additive Manufacturing; Ti-6Al-4V; Probabilistic Modelling; Fatigue; Extreme Value Statistics; Materialteknik; Engineering Materials;

    Abstract : Additive manufacturing (AM), of metals is gaining popularity as an alternative to conventional manufacturing techniques such as casting and forging. Metal-AM allows for the production of complex part geometries with reduced material waste and shorter lead times. READ MORE

  7. 5. Human Behaviour in Social-Ecological Systems : Insights from economic experiments and agent-based modelling

    Author : Caroline Schill; Therese Lindahl; Anne-Sophie Crépin; Johan Colding; Carl Folke; Juan Camilo Cárdenas; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Human behaviour; Common-pool resources; Ecological complexity; Collective action; Sustainable resource use; Regime shifts; Thresholds; Uncertainty; Communication; Knowledge-sharing; Economic experiments; Laboratory and field experiments; Agent-based modelling; Complex adaptive systems; Social-ecological systems; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : Progress towards sustainability requires changes in our individual and collective behaviour. Yet, our fundamental understanding of behaviour in relation to environmental change remains severely limited. READ MORE
