2. 16. Road user charging for heavy goods vehicles - Implementation aspects

   Author : Eva Schelin; Peter Värbrand; Clas Rydergren; Lena Trojer; Eric Sampson; Linköpings universitet; []
   Keywords : road user charging; heavy goods vehicles; distance based; marginal cost principle; implementation model; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Several factors have influenced the recent development in charging of heavy goods vehicles in Europe. European legislation is changed and the political will is strong in many countries. The public awareness and acceptance is large for the need to put a price and a cost on the use of infrastructure. READ MORE

4. 17. Simulation Studies for Improved Efficiency in Road and Rail Freight Transports

   Author : Ingrid Johansson; Markus Bohlin; Oskar Fröidh; Behzad Kordnejad; Carl-William Palmqvist; C. Tyler Dick; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy-duty vehicle platooning; road traffic simulation; intelligent transport systems; optimal control; longitudinal cruise control; fuel economy; railway traffic simulation; microscopic simulation; macroscopic simulation; freight trains; early departures; capacity; railway stations; strategic planning; timetable compression; UIC Code 406; Transportsystem; Transport Systems;

   Abstract : The demand for road and rail freight transport continues to grow with the expanding economy, while the climate crisis requires reduction in greenhouse gas emissions. Therefore, tools and solutions for reducing fossil fuel use and enabling more efficient use of infrastructure are needed. READ MORE

5. 18. Remote Acoustic Characterization of Thin Sheets

   Author : Etienne Mfoumou; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Remote acoustic excitation; material characterization; acoustic NDT; vibration-based technique; sheet material evaluation; fracture toughness.;

   Abstract : There is a need to monitor the existence and effects of damage in structural materials. Aircraft components provide a much publicized example, but the need exists in a variety of other structures, such as layered materials used in food packaging industries. READ MORE

6. 19. The Invisible Landscapes : The Construction of New Subjectivities in the Era of the Mobile Telephone

   Author : Miya Yoshida; Konsthögskolan i Malmö; []
   Keywords : HUMANIORA; HUMANITIES; Subjectivities; Art History; Digital Network; Mobile Telecommunication; Geopolitics; Konstvetenskap;

   Abstract : The interventions of portable digital devices such as mobile telephones, mp3 players, PDAs and many others, have contributed to the formation of contemporary notions of space. The impact of these devices' mobility (informing the users' mobility) could even be paralleled to the shift from the effects of still photography to those of film in the 19th century. READ MORE

7. 20. Evolutionary ecology of arctic char (Salvelinus alpinus (L.)) : Intra- and interspecific interactions in circumpolar populations

   Author : Johan Hammar; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Arctic char; Salvelinus alpinus; biogeography; niche; life history; population ecology; intra- and interspecific interactions; cannibalism; competition; landlocked; marginal populations; species border; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Animal Ecology; zooekologi;

   Abstract : This thesis examines a suite of ecological and genetic mechanisms influencing the fundamental and realized niche borders of European and North American populations of the Arctic char (Salvelinus alpinus (L.)) species complex in allopatry as well as in sympatry with brown trout (Salmo trutta) or brook trout (Salvelinus fontinalis).
