  1. 1. Utilization of local bioresources for transport fuels - System analysis for decision support

    Författare :Muhammad Arfan; Ola Eriksson; Jonas Ammenberg; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System analysis; local bioresources; transportation fuels; LCA; LCC; geography of transitions; Systemanalys; Lokala resurser; drivmedel; LCA; LCC; geografi och om-ställning;

    Sammanfattning : This thesis presents a comprehensive system analysis of the utilization of biowaste and forest industry residues to produce transportation fuels. It explores various aspects such as the constraints to the production system’s value chain development, the utilization of the geographical proximity of biofuel technology innovation system components, environmental impacts, and economic costs.

  3. 2. Bridging Local Constraints and Global Priorities : The Shaping of Swedish Biogas Markets

    Författare :Nancy Brett; Kristina Trygg; Stefan Andersson; Harald Rohracher; Tomas Moe Skjølsvold; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Biofertiliser; Marketisation; Valuation; Regional studies; Sweden; Biogas; Biogödsel; Marknadisering; Värdering; Regionala studier; Sverige;

    Sammanfattning : Biogas offers a sustainable alternative to fossil fuels, promoting circularity and local economic growth. It is, therefore, increasingly prioritised by decision-makers within Sweden and the EU. Despite its advantages, the Swedish market is perceived as underachieving in terms of scale and penetration.

  4. 3. The influence of multiscale hyporheic flow on solute transport : Implications for stream restoration enhancing nitrogen removal

    Författare :Ida Morén; Anders Wörman; Joakim Riml; Roy Haggerty; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Hyporheic exchange flow; Hydrological modeling; Solute transport; Stream restoration; Nitrogen; Power spectral analysis; Hydraulic and Hydrologic Engineering; Hydraulik och teknisk hydrologi;

    Sammanfattning : Stream water that flows into and out of streambeds is called hyporheic exchange flow (HEF).It continuously interacts with groundwater and thereby affect the water quality of local streamreaches as well as downstream recipients by providing an environment where solutes andenergy can be retained and degraded.

  5. 4. Multi-Scale Surface Water-Groundwater Interaction : Implications for GroundwaterDischarge Patterns

    Författare :Babak Brian Mojarrad; Anders Wörman; Joakim Riml; Jan Fleckenstein; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; groundwater flow; hyporheic zone; multi-scale modeling; spectral analysis; fragmentation of discharge zones; characteristic parameters; Hydraulik och teknisk hydrologi; Hydraulic and Hydrologic Engineering;

    Sammanfattning : Rivers and aquifers are continuously exchanging water, driven by processes that occur on various temporal and spatial scales, ranging from small streambed features to large geological structures. The interaction between these two components occurs in permeable sediments below the stream channel, called the hyporheic zone. LÄS MER

  7. 5. Towards a Scenario-based Spatial Dynamic Modeling for Predicting Urban Land Use Change : Planning Tools and Comparative Analysis

    Författare :Zipan Cai; Vladimir Cvetkovic; Fredrik Gröndahl; Brian Deal; Stan Geertman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; urbanization; planning support system; spatial dynamic model; urban land use change; spatial analysis; human-land interaction; socioeconomics; ecological systems; urban amenities; environmental impact assessment; what-if; decision-making; urbanisering; planeringsstödsystem; rumslig dynamisk modell; förändring av stadsmarkanvändning; rumslig analys; mänsklig-land interaktion; socioekonomi; ekologiska system; urbana bekvämligheter; miljökonsekvensbeskrivning; vad-om; beslutsfattande; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : As global urbanization progresses, cities worldwide are growing in size, which leads to many economic, environmental, and management challenges. Recent advancements in spatial data analysis and algorithmic geography have also led to the development of various urban model-based planning support systems (PSS) for urban planning. LÄS MER
