1. 31. Living in a predation matrix : Studies on fish and their prey in a Baltic Sea coastal area

   Författare :Ida Ahlbeck; Sture Hansson; Hannu Lehtonen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diet analysis methods; Sander lucioperca; behaviour; rearing environment; diel vertical migration; Acartia spp.; Eurytemora affinis; Perca fluviatilis; stable isotopes; body condition; sedentarity; Marine Ecology; marin ekologi;

   Sammanfattning : This thesis was written within the framework of a biomanipulation project where young-of-the-year (YOY) pikeperch (Sander lucioperca) were stocked to a Baltic Sea bay to improve water quality through a top-down trophic cascade. The aim of my doctorial studies was however focused on a broader ecological question, namely predation (the main driving force in a biomanipulation). LÄS MER

3. 32. Survival of the Tamest : The Domesticated Phenotype in Red Junglefowl Selected for Tameness

   Författare :Rebecca Katajamaa; Per Jensen; Dominic Wright; Ruth C. Newberry; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; domestication; chicken; red junglefowl; tameness; brain size; behaviour; cognition; body size;

   Sammanfattning : Early animal domestication was probably associated with reduced fear of humans. Domestication is a process in which animals adapt to humans and the captive environment provided by humans. Selection on tameness as the only trait has previously been found to generate changes in other phenotypes in different animal species. LÄS MER

4. 33. Energy Consumption and Running Time for Trains : modelling of running resistance and driver behaviour based on full scale testing

   Författare :Piotr Lukaszewicz; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy consumption; Running time; running resistance; driver behaviour; freight; train; energy coasting method; aerodynamic drag; driver model; degree of coasting; slippage; wind; Energy saving; braking ratio; powering ratio; full scale testing; Vehicle engineering; Farkostteknik;

   Sammanfattning : The accuracy in determined energy consumption and runningtime of trains, by means of computer simulation, is dependent upon the various models used. This thesis aims at developing validated models of running resistance, train and of a generaldriver, all based on full scale testing. LÄS MER

5. 34. Driver interaction with vulnerable road users: Modelling driver behaviour in crossing scenarios

   Författare :Christian-Nils Åkerberg Boda; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driver behaviour; Counterfactual analysis; Pedestrian; Driver model; Active Safety; Bicyclist; Euro NCAP;

   Sammanfattning : Every year, more than 5000 pedestrians and 2000 cyclists die on European roads. These vulnerable road users (VRUs) are especially at risk when interacting with cars. Intelligent safety systems (ISSs), designed to mitigate or avoid crashes between cars and VRUs, first entered the market a few years ago, and still need to be improved to be effective. LÄS MER

7. 35. Truck Tyre Vibration Behaviour. Measurements and High Frequency Modelling

   Författare :Penka Dinkova; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration response; mobility measurements; truck tyre; heavy vehicle; tyre-road noise; tyre; driving point mobility; transfer mobility; tire; vibration prediction; model;

   Sammanfattning : To facilitate tyre-road noise prediction, a computationally efficient high frequency tyre model is needed. Such models are always a compromise between the desired accuracy and the need for simplicity. In addition the accuracy of models is often limited by the quality of the input data available. LÄS MER
