  2. 1. Artefactual Intelligence: The Development and Use of Cognitively Congenial Artefacts

    Author : David de Léon; Kognitionsvetenskap; []
    Keywords : HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; pervasive computing; affective computing; persuasive computing; Psychology; Psykologi; computer-mediated extrospection; precommitment; self-control; situated cognition; distributed motivation; cognitive ethnography; distributed cognition; cognitive biographies; redesign; task–artefact cycle; artefact evolution; artefact design; task structure; cognitive task; cognitive congeniality; artefactual intelligence; cognitive artefacts; task environment; tools; Cognition; artefacts; ubiquitous computing;

    Abstract : How can tools help structure tasks to make them cognitively easier to perform? How do artefacts, and our strategies for using them, develop over time in cognitively beneficial ways? These are two of the main questions that are explored in the five papers collected in this thesis. The first paper details an ethnographic study conducted on people cooking in their homes. READ MORE

  5. 3. Solid Waste Landfills in an Arid Environment : Site Selection and Design

    Author : Ali Chabuk; Jan Laue; Nadhir Al-Ansari; Sven Knutsson; Hussain M. Hussain; Roland Pusch; Rafid Alkhaddar; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Landfill; Arid Environment; Site selection; Design; Babylon; Iraq; Soil Mechanics; Geoteknik;

    Abstract : Selecting landfill sites is considered a complicated task because its whole process is based upon several factors and restrictions. This study shows the present status of solid waste management, sources, collection personnel, machinery and equipment that are involved in the waste collection process, financing and financial management for the major cities of the Babylon Governorate in Iraq (Al-Hillah, Al-Qasim, Al-Mahawil, Al-Hashimiyah and Al-Musayiab).

  6. 4. Dynamic Abstraction for Interleaved Task Planning and Execution

    Author : Per Nyblom; Patrick Doherty; Lars Karlsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Artificial Intelligence; Dynamic Abstraction; Task Planning; Automatic Model Construction; Meta-modelling; Computer science; Datavetenskap;

    Abstract : It is often beneficial for an autonomous agent that operates in a complex environment to make use of different types of mathematical models to keep track of unobservable parts of the world or to perform prediction, planning and other types of reasoning. Since a model is always a simplification of something else, there always exists a tradeoff between the model’s accuracy and feasibility when it is used within a certain application due to the limited available computational resources.

    Abstract : This thesis is concerned with measurements of persistent organic pollutants (POPs) in environmental samples. The POPs consist of several groups of compound with many isomers, hence analysing POPs in a complex environment is a This thesis is concerned with measurements of persistent organic pollutants (POPs) in environmental samples.
