1. 21. Dispersion and Transformation of Traffic Exhaust Particles in the Urban Atmosphere

   Författare :Matthias Ketzel; Kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; condensation; deposition; dilution; particle size distribution; plume model; street canyon; traffic pollution; urban environment; turbulence; aerosol dynamics modelling; coagulation; Physics; Fysik; Fysicumarkivet A:2004:Ketzel;

   Sammanfattning : Ultrafine particles, their sources and fate in the atmosphere are currently key issues in atmospheric research owing to concern about their effects on human health and global climate. Traffic emissions are a dominating source of ultrafine particles, especially in urban areas. LÄS MER

3. 22. Studies of ash transformation processes in thermochemical co-conversion of phosphorus-rich manure and sludge with biomass residues

   Sammanfattning : Efficient use of resources and sustainable recovery of various materials are important to minimize the anthropogenic impact on the climate and environment. One such resource is the phosphorus (P) present in manure and sewage sludge. LÄS MER

4. 23. Sustainable Electromobility : A System Approach to Transformation of Transportation

   Författare :Harrison John Bhatti; Mike Danilovic; Rune Wigblad; Statens väg- och transportforskningsinstitut; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Energy system; Transportation System; System Approach; Symbiotic Business Model; Innovation Ecosystem; Technology Readiness; Political Readiness; Societal Readiness; Economic Readiness;

   Sammanfattning : This thesis aims to explore, analyze, and develop knowledge that leads to an understanding of identifying the key actors and their symbiotic relationships and dependencies in transforming the energy and transportation system from fossil-based to renewable and fossil fuel-powered vehicles to electric. The research was explorative and categorized into two studies.

5. 24. Designing Electricity Distribution Network Charges for an Efficient Integration of Distributed Energy Resources and Customer Response

   Författare :Ibtihal Abdelmotteleb; Tómas Gómez; Javier Reneses; Rafael Cossent Árin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; customer response; distributed energy resources; distribution network charges; local flexibility mechanisms; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : A significant transformation has been gradually taking place within the energy sector, mainly as a result of energy policies targeting environmental objectives. Consequently, the penetration of Distributed Energy Resources (DERs) has been escalating, including self-generation, demand side management, storage, and electrical vehicles. LÄS MER

7. 25. Deformation and martensitic phase transformation in stainless steels

   Författare :Peter Hedström; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

   Sammanfattning : The use of high-energy synchrotron x-rays which has enabled three- dimensional structural characterization from the nano- to the macroscopic scale, and now to the meso-scale, such as individual grains and dislocation structures, is a major scientific advance. This is the first technique with sufficient spatial resolution and penetration power to probe the local structure embedded deep within the material. LÄS MER
