  1. 11. Multi-target Tracking Using on-line Viterbi Optimisation and Stochastic Modelling

    Författare :Håkan Ardö; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : To study and compare the safety of intersection, traffic scientists today typically manually monitor the intersection during several days and count how often certain events such as evasive manoeuvres occur. This is a laboursome and costly procedure. LÄS MER

  3. 12. Demand Flexibility for the Simultaneous Provision of Multiple Services : Tapping the Potential of Controllable Electric Loads for Frequency Reserves and Energy Arbitrage

    Författare :Lars Herre; Lennart Söder; Qiuwei Wu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aggregator; chance constrained optimisation; demand response; de-mand response provider; demand side management; frequency reserves; load control; stochastic optimization; aggregator; riskbegränsad optimering; efterfrågestyrning; leverantör av efterfrågesvar; efterfrågeflexibilitet; frekvensreserver; laststyrning; stokastisk optimering.; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Power systems with increasing shares of renewable energy sources require sufficient flexibility sources. One source of flexibility for future power systems is constituted by flexible electric loads. The concept of demand response captures the utilization of demand side flexibility to provide services to the power system. LÄS MER

  4. 13. 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 :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 : The topical issue of climate change has increasingly become important as scenarios indicate an increase of 2.5–7.8°C in the global mean temperature by the end of this century, if no greenhouse gas emissions are reduced. LÄS MER

  7. 15. Towards Precise Localisation : Subsample Methods, Efficient Estimation and Merging of Maps

    Författare :Gabrielle Flood; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; localisation; map merging; subsample; stochastic analysis; time-difference-of-arrival;

    Sammanfattning : Over the last couple of years audio and radio sensors have become cheaper and more common in our everyday life. Such sensors can be used to form a network, from which one can obtain distance measures by correlating the different received signals. LÄS MER
