2. 1. Evolutionary consequences of maternal effects and stress

   Author : Piotr K. Rowiński; Björn Rogell; Karl Gotthard; Katja Räsänen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; parental effects; meta-analysis; development time; bet-hedging; brain size; evolutionary potential; unpredictable environments; zoologisk ekologi; Animal Ecology;

   Abstract : Maternal effects occur when maternal environment or phenotype influence offspring phenotype, in addition to genetic contribution of the mother. As maternal effects often influence phenotypes that are under natural selection, they hence have evolutionary consequences. READ MORE

4. 2. Dynamics of ecological communities in variable environments : local and spatial processes

   Author : Linda Kaneryd; Bo Ebenman; Peter Münger; Michael S. Fowler; Linköpings universitet; []
   Keywords : ;

   Abstract : The ecosystems of the world are currently facing a variety of anthropogenic perturbations, such as climate change, fragmentation and destruction of habitat, overexploitation of natural resources and invasions of alien species. How the ecosystems will be affected is not only dependent on the direct effects of the perturbations on individual species but also on the trophic structure and interaction patterns of the ecological community.

5. 3. A Novel Method for Adaptive Control of Manufacturing Equipment in Cloud Environments

   Author : Göran Adamson; Philip Moore; Lihui Wang; Robert Harrison; Högskolan i Skövde; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Function Block; Adaptive control; Robot-Control-as-a-Service; Cloud Manufacturing; Production and Automation Engineering; Produktion och automatiseringsteknik;

   Abstract : The ability to adaptively control manufacturing equipment, both in local and distributed environments, is becoming increasingly more important for many manufacturing companies.One important reason for this is that manufacturing companies are facing increasing levels of changes, variations and uncertainty, caused by both internal and external factors, which can negatively impact their performance.

6. 4. Mobility and emigration in butterflies

   Author : Karin Enfjäll; Olof Leimar; Michel Baguette; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Keywords: conspecific density; dispersal; evolution; flight-behaviour; information; sexual conflict; social interactions; Ethology and behavioural ecology; Etologi och beteendeekologi; etologi; Ethology;

   Abstract : Because of its implications for the survival of many species, dispersal plays a key role in conservation biology. A good knowledge about the different factors that influence dispersal decisions is crucial for the understanding of inter-population movements. READ MORE

7. 5. On intelligent automation systems

   Author : Endre Erös; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automated planning; Automation; testing and coverability.; modeling; virtual preparation and commissioning; robot operating system;

   Abstract : Developing automation systems that are capable of handling dynamic and unpredictable situations is a challenging task, as it requires adapting to a changing environment and managing potentially unforeseen action outcomes. In contrast to traditional automation, where control code is explicitly pro- grammed, a model-based approach might be a more appropriate solution for automating such systems. READ MORE
