  4. 2. Efficient energy use in different applications

    Author : Lars Johansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Abstract : There is a steadily growing awareness for environmental issues caused by the increased energy use, mainly in the industrial world. The use of fossil fuels has reached the point where it can not be looked at as an endless source, the resources are decreasing at a pace where alternative energy sources will be a necessity for this and future generations.

  5. 3. Energy Absorbing Material Concepts for Automotive Accident Injury Prevention

    Author : Rickard Juntikka; KTH; []
    Keywords : Head impact; energy absorption; cellular materials; automotive; dynamic; pedestrian; interior; compression; shear; finite element analysis; optimisation;

    Abstract : Although automotive safety has experienced a rapiddevelopment during the last decades, traffic related accidentsrank very high in many countries in terms of cause of death.Statistics show that the head is the body region mostfrequently injured in motor vehicle accidents and the primarycause of death is head injuries.

  6. 4. 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.

  7. 5. Towards Optimal Real-Time Automotive Emission Control

    Author : Jonathan Lock; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic programming; optimal control methods; hybrid vehicles; three way catalyst modelling; Automotive emissions control;

    Abstract : The legal bounds on both toxic and carbon dioxide emissions from automotive vehicles are continuously being lowered, forcing manufacturers to rely on increasingly advanced methods to reduce emissions and improve fuel efficiency. Though great strides have been made to date, there is still a large potential for continued improvement. READ MORE
