  1. 1. Computational and spatial analyses of rooftops for urban solar energy planning

    Författare :Mohammad Aslani; Stefan Seipel; S. Anders Brandt; Julia Åhlén; Alison Jane Heppenstall; Högskolan i Gävle; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Machine learning; Classification; Segmentation; Support vector machines; Instance selection; Rooftop plane segmentation; Photovoltaic panels; Utiliz-able rooftop areas; Geoinformatics; maskininlärning; klassificering; segmentering; stödvektormaskiner; urval av träningsdata; segmentering av takytor; solcellspaneler; utnyttjande av takytor; geoinformatik; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : In cities where land availability is limited, rooftop photovoltaic panels (RPVs) offer high potential for satisfying concentrated urban energy demand by using only rooftop areas. However, accurate estimation of RPVs potential in relation to their spatial distribution is indispensable for successful energy planning. LÄS MER

  3. 2. What's in your mind? : Collegial Verbalisation – An ecological approach to knowledge elicitation

    Författare :Mikael Erlandsson; Anders Jansson; Stefan Seipel; Neville Stanton; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot människa-datorinteraktion; Computer Science with specialization in Human-Computer Interaction;

    Sammanfattning : Knowledge elicitation of the work of professional operators, using traditional methods such as concurrent or retrospective verbalization is problematic. Concurrent verbalization distracts the operators from their primary task, and the operators have difficulties in verbalizing about their automated work tasks. LÄS MER

  4. 3. Modelling, mapping and visualisation of flood inundation uncertainties

    Författare :Nancy Joy Lim; Stefan Seipel; S. Anders Brandt; Eva A. U. Sahlin; Matthew Wilson; Högskolan i Gävle; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cartography; flood; hydraulic modelling; GIS; map; uncertainty; visualisation; GIS; hydraulisk modellering; karta; kartografi; osäkerhet; visualisering; översvämning; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : Flood maps showing extents of predicted flooding for a given extreme event have wide usage in all types of spatial planning tasks, as well as serving as information material for the public. However, the production processes that these maps undergo (including the different data, methods, models and decisions from the persons generating them), which include both Geographic Information Systems (GIS) and hydraulic modelling, affect the map’s content, and will be reflected in the final map.

  5. 4. Hand-held Augmented Reality for Facility Maintenance

    Författare :Fei Liu; Stefan Seipel; Julia Åhlén; Ewert Bengtsson; Xiangyu Wang; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Augmented reality; Façade; Image registration; Thermal infrared imaging; Facility management; Third person perspective; Target designation; Precision study; Experiment; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Buildings and public infrastructures are crucial to our societies in that they provide habitations, workplaces, commodities and services indispensible to our daily life. As vital parts of facility management, operations and maintenance (O&M) ensure a facility to continuously function as intended, which take up the longest time in a facility’s life cycle and demand great expense.

  7. 5. Computational and Visual Tools for Geospatial Multi-Criteria Decision-Making

    Författare :Goran Milutinovic; Stefan Seipel; Ulla Ahonen-Jonnarth; S. Anders Brandt; Gennady Andrienko; Högskolan i Gävle; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geographic information systems; multi-criteria decision-making; interactive visualization; even swaps; Hållbar stadsutveckling; Sustainable Urban Development; Intelligent industri; Intelligent Industry;

    Sammanfattning : Geospatial multi-criteria decision-making usually concerns quasi-continuous choice models, with the number of alternatives constrained only by the limits of the used representation model. This sets high demands on the decision-making methods used in the context. LÄS MER
