2. 6. Improving Fuel Efficiency of Commercial Vehicles through Optimal Control of Energy Buffers

   Author : Mohammad Khodabakhshian; Jan Wikander; Lei Feng; Johan Ölvander; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy buffer; Optimal control; Hybrid electric vehicle; Engine cooling system; Equivalent consumption minimization strategy; Model predictive control; Machine Design; Maskinkonstruktion;

   Abstract : Fuel consumption reduction is one of the main challenges in the automotiveindustry due to its economical and environmental impacts as well as legalregulations. While fuel consumption reduction is important for all vehicles,it has larger benefits for commercial ones due to their long operational timesand much higher fuel consumption. READ MORE

4. 7. Biomass Energy Systems and Resources in Tropical Tanzania

   Author : Lugano Wilson; Weihong Yang; Wlodzimierz Blasiak; Truls Liliedahl; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tanzania; Tropical Biomass Energy; High Temperature Gasification HTAG ; Mechanical energy engineering; Mekanisk energiteknik;

   Abstract : Tanzania has a characteristic developing economy, which is dependent on agricultural productivity.  About 90% of the total primary energy consumption of the country is from biomass.  Since the biomass is mostly consumed at the household level in form of wood fuel, it is marginally contributing to the commercial energy supply.

5. 8. Modelling Wave Power by Equivalent Circuit Theory

   Author : Ling Hai; Mats Leijon; Rafael Waters; Yongliang Zhang; Uppsala universitet; []
   Keywords : Wave energy; hydrodynamics; electric circuit; electrical analogy; energy absorption; force; system modelling; Simulink; engineering science; renewable energy; Teknisk fysik med inriktning mot elektricitetslära; Engineering Science with specialization in Science of Electricity;

   Abstract : The motion of ocean waves can be captured and converted into usable electricity. This indicates that wave power has the potential to supply electricity to grids like wind or solar power. A point absorbing wave energy converter (WEC) system has been developed for power production at Uppsala University. READ MORE

   Abstract : Conventional wastewater treatment plants are designed for treating manmade wastewater (e.g., from households and industries) and to protect the environment (e.g. READ MORE

7. 10. Life cycle assessment and life cycle cost analysis of a single-family house

   Author : Bojana Petrovic; Ola Eriksson; Marita Wallhagen; Xingxing Zhang; Åsa Wahlström; Högskolan i Gävle; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building; carbon-dioxide equivalent emissions; global warming potential; primary energy use; life cycle assessment; life cycle cost; Byggnad; koldioxidekvivalenta utsläpp; global uppvärmningspotential; pri-märenergianvändning; livscykelbedömning; livscykelkostnad; Hållbar stadsutveckling; Sustainable Urban Development;

   Abstract : The building industry is responsible for 35% of final energy use and 38% of CO2 emissions at a global level. The European Union aims to reduce CO2 emissions in the building industry by up to 90% by the year 2050. Therefore, it is important to consider the environmental impacts buildings have. READ MORE
