  1. 1. Multi-year maintenance optimisation for paved public roads - segment based modelling and price-directive decomposition

    Författare :Per-Åke Andersson; Per Olov Lindberg; Torbjörn Larsson; Jonathan Bard; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; road maintenance optimisation; price-directive decomposition; Optimization; systems theory; Optimeringslära; systemteori;

    Sammanfattning : I avhandlingen studeras hur kostnadseffektiva underhålls- (uh-)planer för belagd väg kan genereras, på basis av information om aktuellt vägytetillstånd och funktionella modeller för kostnads- och tillståndsförändringar, delvis utvecklade i samarbete med svenska Vägverket (VV). Tilltänkt användning är på strategisk och programnivå, innan mer detaljerad objektinformation finns att tillgå. LÄS MER

    Sammanfattning : In Kenya, mobile technology is widely used, with more and more people gaining access to the Internet. Mobile technology has the potential to support learning and improve lives, particular those of impoverished people. In this study, 30 Kenyan runners from poor backgrounds and with limited formal education participated. LÄS MER

  3. 3. Efficient Modelling and Synthesis of Data Intensive Reconfigurable Systems

    Författare :Per Andersson; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; kontroll; Systems engineering; numerisk analys; system; control; Datalogi; numerical analysis; systems; Data Flow Graphs; Data Flow Modlling; computer technology; Data- och systemvetenskap; Computer science; Hardware Compilation; Synthesis;

    Sammanfattning : Digital systems are integrated in our environment and have become a natural part of our every day life. As we rely more on these systems our expectations on them increases. We expect them to perform new tasks, communicate and cooperate. The complexity of these systems are increasing. LÄS MER

  4. 4. Modelling and Implementation of a vision system for embedded systems

    Författare :Per Andersson; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Today more and more functionality is included in embedded systems, resulting in an increased system complexity. existing design methodologies and design tools are not adequate to deal with this increase in complexity. To overcome these limitations application specific design solutions are more common. LÄS MER

  5. 5. Theoretical Investigations of Selected Heavy Elements and Metal-hydrogen Systems by Means of Electronic Structure Calculations

    Författare :Per Andersson; Manuel RichterI; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Physics; actinides; metal-hydrogen systems; DFT; band structure; non-commensurate magnetism; Fysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : Using ab initio electronic structure calculations based on density functional theory the crystal, electronic and magnetic structures of selected materials have been investigated. The materials which are the subjects of these investigations can be divided into two groups. LÄS MER
