  2. 11. The Scents of Nature : Identification and Synthesis of Bioactive Compounds Used in Insect Communication

    Author : Erika Wallin; Erik Hedenström; Anna-Karin Borg-Karlson; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Semiochemicals; Sex pheromone; Bicyclus spp; Euglossa spp; Cimex hemipterus; Cimex lectularius; Kladothrips nicolsoni; Kladothrips rugosus; Drosophila melanogaster;

    Abstract : Pest insects cause great financial losses in the forest and food industry every year. To fight these pests industries have used insecticides, which are sometimes harmful to nature and humans. READ MORE

  4. 12. New opportunities provided by the Swedish electricity meter reform

    Author : Fredrik Wallin; Erik Dahlquist; Eva Thorin; Peter Roots; David Natusch; Mälardalens högskola; []
    Keywords : automatic meter reading AMR ; advanced metering infrastructure AMI ; peak load; consumption patterns; visualize; consumption feed-back; added values; demand-based; tariffs; bottom-up modeling; web-based applications; TECHNOLOGY; TEKNIKVETENSKAP; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The reduction of the impact of energy consumption is a priority issue and a major challenge that concerns every country in the world. This is a complex task that needs to be tackled from several angles in the search for areas where optimizations and savings can be made. READ MORE

  5. 13. Molecular Dynamics Simulations of Fluid Lipid Membranes

    Author : Erik G. Brandt; Olle Edholm; Mats Wallin; Markus Deserno; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biological fluid dynamics; biomembranes; hydrodynamics; lipid bilayers; molecular dynamics; neutron spin echo;

    Abstract : Lipid molecules form thin biological membranes that envelop all living cells, and behave as two-dimensional liquid sheets immersed in bulk water. The interactions of such biomembranes with their environment lay the foundation of a plethora of biological processes rooted in the mesoscopic domain - length scales of 1-1000 nm and time scales of 1-1000 ns.

  6. 14. Energy Optimal Operation of Electric Trains : Development of a Driver Advisory System

    Author : Nima Ghaviha; Erik Dahlquist; Markus Bohlin; Fredrik Wallin; Evert Andersson; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The electric traction system used in trains is the most energy efficient traction system in the transportation sector. Moreover, it has the least NOx and CO2 emissions in comparison to other transportation systems (e.g. busses, passenger cars, airplanes, etc. READ MORE

  7. 15. Increasing Energy Efficiency in Electric Trains Operation : Driver Advisory Systems and Energy Storage

    Author : Nima Ghaviha; Erik Dahlquist; Markus Bohlin; Fredrik Wallin; Rob M.P. Goverde; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driver Advisory System; Catenary-free Operation; Electric Train; Electric Multiple Unit; Battery; Energy Efficiency; Energy Storage; Speed Profile Optimization; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Electric traction is the most efficient traction system in the railway transportation. However, due to the expensive infrastructure and high power demand from the grid, the share of electric trains in the railway transportation is still lower than other trains. READ MORE
