2. 1. Dynamic modelling of the forest ecosystem: Incorporation of the phosphorus cycle

   Author : Lin Yu; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dynamic modeling; forest ecosystem; phosphorus cycle;

   Abstract : The forest ecosystem provides and regulates many important ecosystem services, such as soil and water protection, timber production, and climate regulation. It has been influenced by changes induced by humans, for example, our increasing demand for timber and bioenergy, the increase in nitrogen (N) deposition and CO2 concentrations due to industrialization, and climate change which has caused an increase in global temperature and extreme events such as storms.

4. 2. Direct and indirect pressures of climate change on nutrient and carbon cycling in northern forest ecosystems : Dynamic modelling for policy support

   Author : Klas Lucander; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Forest; boreal ecosystems; Forest biogeochemistry; Forest bioenergy; Boreal coniferous forest; base cations; Biogeochemical cycles; Dynamic Modelling; Carbon cycle; nitrogen cycle; decision support; policy-making; Weathering; Forestry; Land use change;

   Abstract : Northern forest ecosystems play an important role in mitigating climate change by sequestrating carbon (C), while additionally providing and regulating other ecosystem services. A majority of the Swedish environmental quality objects (EQOs) that guide Swedish environmental policy and management are associated with the forest, and they have proven difficult to achieve.

5. 3. Designing dynamic textile patterns

   Author : Linda Worbin; Högskolan i Borås; []
   Keywords : HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; smart textiles; textile design; dynamic textile patterns;

   Abstract : Designing Dynamic Textile Patterns Progress in chemistry, fibres and polymers technology provides textile designers with new expressive materials, making it possible to design dynamic textile patterns, where several different expressions are inherent in the same textile, textiles that, for example, could alternate between a striped and checkered pattern. Textiles are traditionally designed and produced to keep a given, static expression during their life cycle; a striped pattern is supposed to keep its stripes. READ MORE

6. 4. Modeling and Testing of Insulation Degradation due to Dynamic Thermal Loading of Electrical Machines

   Author : Zhe Huang; Industriell elektroteknik och automation; []
   Keywords : thermal degradation; thermal cycle; dynamic temperature; thermal-mechanical; fatigue; electrical insulation system; accelerated testing; condition monitoring; electrical machine; electrified vehicles;

   Abstract : Electrical machines in electrified vehicles are subjected to dynamic loadings at different driving conditions, which results in dynamic temperatures. The aging of the Electrical Insulation System (EIS) in electrical machines is caused by these dynamic temperatures, namely high average temperatures and temperature cycles. READ MORE

7. 5. Operating cycle representations for road vehicles

   Author : Pär Pettersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating cycle; full vehicle simulation; energy usage; transport operation description; road format; CO2 emissions;

   Abstract : This thesis discusses different ways to represent road transport operations mathematically. The intention is to make more realistic predictions of longitudinal performance measures for road vehicles, such as the CO2 emissions. READ MORE
