2. 1. Colour patterns in warning displays

   Author : Marianne Aronsson; Gabriella Gamberale-Stille; Olof Leimar; Candy Rowe; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; aposematism; warning colouration; colour patterns; avoidance learning; generalization behaviour; signal design; signal evolution; conspicuousness; mimicry; etologi; Ethology;

   Abstract : In aposematism a prey species use bright colours, often combined with a black contrasting pattern, to signal unprofitability as prey to potential predators. Although there are several different hypotheses about the presence of these internally contrasting patterns, there is little experimental evidence of any beneficial effects. READ MORE

4. 2. Developing Theoretical and Empirical Definitions of Safety Problems in Driving Suitable for Active Safety Function Evaluation

   Author : Mikael Ljung Aust; Chalmers tekniska högskola; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; avoidance; driver behaviour; pre-crash scenarios; crash causation; adaptation; motivation; conceptual framework; active safety functions;

   Abstract : In passive safety, the requirement specifications used for evaluation of protective functions are both standardised and specified at a high level of detail regarding evaluation scenario definition, performance metrics and pass/fail criteria. For active safety, while several propositions for evaluation scenarios have been made, neither these, nor performance metrics and pass/fail criteria have yet reached a similar level of detail and standardisation.

5. 3. A study of the fatigue behaviour of laser and hybrid laser welds

   Author : Md. Minhaj Alam; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

   Abstract : This licentiate thesis focuses on the fatigue cracking behaviour of laser and hybrid laser-MAG welded structures. Beside the welding process and the resulting weld, several topics related to fatigue of welded structures are treated such as; macro and micro surface geometry, weld defects and their influence on fatigue performance of welded structures, fatigue analysis by the nominal and effective notch stress method, fatigue life prediction using LEFM (Linear Elastic Fracture Mechanics), fatigue testing, metallurgical analysis, elastic and elastic-plastic finite element analysis.

6. 4. Objective quantification and analysis of eating behaviour associated with obesity development : from lab to real-life

   Author : Billy Langlet; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Introduction: The last four decades have seen a marked increase in childhood and adult obesity prevalence, attributed to an “obesogenic” environment. Several genetical, environmental and behavioural factors have been identified that increase the risk of obesity, but treatment outcomes are usually modest and the risk of relapse high. READ MORE

7. 5. Characterizing Piecewise Linear Neural Networks

   Author : Anton Johansson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; automotive applications.; neural network; machine learning; piecewise linear;

   Abstract : Neural networks utilizing piecewise linear transformations between layers have in many regards become the default network type to use across a wide range of applications. Their superior training dynamics and generalization performance irrespective of the nature of the problem has resulted in these networks achieving state of the art results on a diverse set of tasks.
