1. 1. Moderate Nominalism and Moderate Realism

   Författare :Christer Svennerlind; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; analytic ontology; moderate nominalism; moderate realism; particular; universal; abstract; concrete; abstract particular; abstract universal; concrete particular; concrete universal; trope; moment; complex unity; collection; instance; unit attribute; intensional aspect; predicational aspect; continuous composite; articulated composite;

   Sammanfattning : The subject matter of this thesis is analytic ontology. Chapters II and III deal with two versions of trope theory, or moderate nominalism; these are defined as ontologies which recognise properties and relations but no (real) universals. The key notion of both theories, trope, is characterised as an abstract particular. LÄS MER

3. 2. Automatic Instance-based Tailoring of Parameter Settings for Metaheuristics

   Författare :Felix Dobslaw; Theo Kanter; Åke Malmberg; Thomas Bartz-Beielstein; Mittuniversitetet; []
   Nyckelord :Algorithm Configuration; Parameter Tuning; Parameter Control; Metaheuristics;

   Sammanfattning : Many industrial problems in various fields, such as logistics, process management, orproduct design, can be formalized and expressed as optimization problems in order tomake them solvable by optimization algorithms. However, solvers that guarantee thefinding of optimal solutions (complete) can in practice be unacceptably slow. LÄS MER

4. 3. 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

5. 4. Dynamic algorithms: new worst-case and instance-optimal bounds via new connections

   Författare :Thatchaphol Saranurak; Danupon Nanongkai; Piotr Sankowski; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datalogi;

   Sammanfattning : This thesis studies a series of questions about dynamic algorithms which are algorithms for quickly maintaining some information of an input data undergoing a sequence of updates. The first question asks \emph{how small the update time for handling each update can be} for each dynamic problem. LÄS MER

7. 5. Object Instance Detection and Dynamics Modeling in a Long-Term Mobile Robot Context

   Författare :Nils Bore; John Folkesson; Joydeep Biswas; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; long-term; mapping; tracking; unsupervised learning; estimation; object modeling; Computer Science; Datalogi;

   Sammanfattning : In the last years, simple service robots such as autonomous vacuum cleaners and lawn mowers have become commercially available and increasingly common. The next generation of service robots should perform more advanced tasks, such as to clean up objects. LÄS MER
