  2. 1. Assessing future effects on lake ecosystem resilience using data analysis and dynamic modelling : Modelling the effects of extreme weather events and climate warming on lakes

    Author : Jorrit P. Mesman; Bastiaan W Ibelings; Stéphane Goyette; Don C Pierson; Karsten Rinke; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extreme events; Storms; Modelling; Climate change; Thermal structure; Phytoplankton;

    Abstract : Extreme weather events can have short-term and long-term effects on lake thermal structure, nutrient dynamics, and community composition. Moreover, changes in lake variables induced by global climate change may influence the response and recovery of lake ecosystems to extreme weather events. READ MORE

  4. 2. Conceptual Modelling of Tasks : A Design Pattern Approach from E-mail to Robots

    Author : Lars Oestreicher; Kerstin Severinson-Eklundh; Gerrit van der Veer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rehabilitation; therapy; Computer and systems science; Data- och systemvetenskap;

    Abstract : HTML clipboardThe thesis deals with the dual problem of finding out and modelling the needs of users in various situations and constructing models of supportive software. Task analysis has not been a very hot topic for research in the last years, but in my work I have tried to apply task analysis to certain application areas. READ MORE

  5. 3. Similarity-based processes in human multiple-cue judgment : evidence from brain imaging and cognitive modelling

    Author : Sara Stillesjö; Linnea Karlsson Wirebring; Lars Nyberg; Håkan Nilsson; Alan Sanfey; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; multiple-cue judgment; similarity-based; rule-based; exemplar-based model; fMRI; cognitive modelling;

    Abstract : Background: We often make judgments that require the consideration of several sources of information. For example, a teacher that grades a student´s exam question often integrates multiple sources of information (cues: details provided in the answer) into a single criterion dimension (the grade).

  6. 4. Lifetime Performance Assessment of Thermal Systems : Studies on Building, Solar and Disctrict Heating Applications

    Author : Bojan Stojanovic; Christer Sjöström; Per Jostein Hovde; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lifetime performance; degradation; assessment; modelling; field exposure; thermal components and system; Building engineering; Byggnadsteknik; Materials science; Teknisk materialvetenskap;

    Abstract : The main questions today concerning thermal systems are their economical and environmental impacts. These entities are generally, at present, assessed on the basis of operation performances of newly installed/designed systems, during an assumed lifetime period. READ MORE

    Abstract : This thesis addresses the topic of grounding in human-robot interaction, that is, the process by which the human and robot can ensure mutual understanding. To explore this topic, the scenario of a robot holding a presentation to a human audience is used, where the robot has to process multimodal feedback from the human in order to adapt the presentation to the human's level of understanding.
