  1. 1. Multi-objective optimization for placing airspace surveillance observers

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Amanda Anderson; [2021-08-13]
    Nyckelord :Facility location; multi-objective optimization; ant colony algorithm; genetic algorithm; pareto optimal; observer placement; 3D viewshed;

    Sammanfattning : Reconnaissance is an important aspect of military planning. Tools that help an alysts monitor and make informed choices are vital for avoiding costly situations. The use of ground-based radar sensors is a common method for monitoring for both land-based and airborne threats. LÄS MER

  3. 2. A concept to evaluate dynamic daylight glare

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Efthymia Eirini Tsianaka; [2018]
    Nyckelord :glare; daylight; zonal; long-term; adaptation possibility; TPG; STG; directional glare; weighting system; dynamic; visual comfort; fenestration system; Arts and Architecture; Technology and Engineering;

    Sammanfattning : A method towards a dynamic daylight glare evaluation in the early stage of design was developed in this thesis, using existing glare metrics under multiple observer positions and gazes. The results pointed out that it is possible for a zonal characterization regarding glare sensation to be achieved with the combination of multiple existing metrics and a weighting system, named the adaptation possibility.
